Description

Dragon Ball vs. Kingdom Hearts! These two girls have shown that they can be just as powerful and recognizable as their male counterparts! But today, it's time to put up or shut up in this bloodbath of a battle! Will Note rise to the challenge and overcome the embracer of destiny or can Kairi manage to triumph over the Saiyan Heroine?

Interlude

(Cue Music: Wiz and Boomstick)

Wiz: Note, the logistical Saiyan Heroine of the Dragon Ball Heroes.

Boomstick: And Kairi, the original persona of Naminé from Kingdom Hearts.

Wiz: Gender barriers have been broken time and time again by the female population, and these two crusaders are no different. As they've proven to become icons in their own ways, today's battle will put their strength and boundary breaks to the test!

Boomstick: He's Wiz and I'm Boomstick!

Wiz: And it's our job to analyze their weapons, armor, and skills to find out who would win... a Death Battle!

Note Brings The Ultimate DEATH BATTLE!

(Cue Music: Fleeting Peace)

Boomstick: Everyone knows how the world of Dragon Ball works these days. Our childhood heroes Goku, Vegeta, Trunks, and many others have had many adventures spread across legends!

Wiz: A story inspired by the Chinese novel, Journey to the West, it tales of Son Goku and friends' adventures to save the universe from dangerous threats. We've covered a lot of these competitors in previous Death Battles, but what if I told you that these heroes would become something more... preserved to the sands of time?

Boomstick: Yeah, Dragon Ball became so popular since its inception that it led to a ton of marketing! Video games, movies, toys, cosplays, everything you can think of! It was everywhere!

Wiz: The widespread popularity of the Dragon Ball series became too taxing that much of the content that they were mass-producing had to be locked behind regions. One of these pieces of media was a Japan-exclusive arcade game that lets you take control of many well-known characters in an RPG card battle. This was known as Dragon Ball Heroes.

(Cue Music: Dragon Ball Heroes: Galaxy Mission Theme)

Boomstick: The game where you get cards of said characters and put them in a 7-on-7 Yu-Gi-Oh style duel and use all sorts of tactics to defeat the opponent! It even puts you into the world via time travel shenanigans! The game was so popular in Japan that it even has a country-wide competitive scene!

Pop-up Note: While the spinoff's not part of the official canon, Dragon Ball creator, Akira Toriyama, supervised the game's design and settings. He also design the 3 Frieza Clan avatars.

Wiz: Being on top of the rankings was very common for those in similar scenarios, but in the case of Heroes, one person in particular wanted to do what she can to reach the mountaintop. That person's name was Note.

BACKGROUND

• Gender: Female
• Age: Early-to-mid teens
• Hero Class: Saiyan Heroine
• Allegiance: Super Dragon Ball Heroes, Time Patrol
• Mentors: Sora (not the Kingdom Hearts one), Great Saiyaman 3
• In a relationship with Beat
• Expert card player and analyst
• Likely named after the musical unit
• Don't confuse her with Pan!

Boomstick: This girl had played the game for a majority of her life and has gone on to compete in multiple championships to fight the best of the best. In one instance, she even ranked 3rd place in the "Strongest Hero" finals in her hometown, making her one of the most well-known players in the scene.

Wiz: She would also keep tabs of other Dragon Ball Heroes players to make sure what she would get herself into the next time that she faces them. The amount of dedication that she put into being the best Heroes player known to mankind, as well as the thrill of having her avatar join in on the fight, added to what would essentially become something important.

Boomstick: And regardless on which version of Note you're looking at, she's dedicated herself to using what she's got. The Dragon Ball Heroes cards can summon a character of what's on that small paper and use the abilities attributed to them during battle.

Wiz: One of her cards, that of the Grand Minister, can give her and her team more Hero Energy and can increase their strength. Another is that of a Super Saiyan Blue Gogeta card that can cancel out an enemy team's buffs. Sure, it may not be what they actually have in canon, but it's still a card game so these stats are able to help her out when needed.

Boomstick: With her Hero Avatar Card at the ready, she would insert herself into the world of the Z-Fighters and become a Saiyan Heroine, fighting against those stronger than her. Each class has different traits depending on what they choose. From Saiyans, Namekians, or Majins, to even the Supreme Kais, Demon Gods, and God of Destructions!

Wiz: And with these specific arcade machines, these actually act as a method of time travel that allows her to enter specific periods of the Dragon Ball Xenoverse and fight alongside other warriors, like when she was able to travel to the original events of the Tree of Might movie or even witness Goku's godly clash against Beerus the Destroyer.

Boomstick: But it wasn't long before she would suddenly find an equal that would become more close to her. Someone that would actually be on par with her skills. And to her surprise, it was.. a mere rookie.

Pop-Up Note: The multiple timelines of Dragon Ball Heroes also extends to other series, like Dragon Ball Xenoverse and Dragon Ball Online. It should also be noted that Note has shared her adventures with Beat.

Wiz: After an encounter with Beat, the two faced off in a one-on-one SDBH battle which Note surprisingly lost. However, instead of letting this get to her head, she saw this as something new. Someone that could help her become stronger and even become attached to. After they started their new friendship, she would take her skills to the next level.

(Cue Music: Counterattack)

Boomstick: As the Saiyan Heroine, she has the same abilities as any other Saiyan would, such as being able to get a massive boost of power every time she reaches the brink of death, survive in nearly any environment she's put in (regardless of what it is), and can move at surreal speeds!

Wiz: And she's even able to replicate the same martial arts techniques as Goku has, that being Kame-Sennin Ryu, or the Turtle Hermit Style. This is a martial arts inspired by several other real-life fighting styles, one of which derives from that of Bruce Lee, that tests the endurance and strength of a person while also testing that with weighted clothing.

Boomstick: She's even learned to do several techniques that are well-known throughout the series just by remembering and looking!

ABILITIES AND TECHNIQUES

• Flight
• Ki Blasts
  • Energy Flash
• Resistance Skills
• Ki Nullification
• Kiai
• Kamehameha
  • Multiple Kamehameha
  • Friend Kamehameha
  • Super Kamehameha
  • God Kamehameha
  • Big Bang Kamehameha
• Absolute Release Ball
• Galick Gun
• Big Bang Attack
• Gigantic Meteor
• Omega Blaster
• God Slicer
• Revenger Cannon
• Sphere of Destruction
• Spirit Bomb
• Spirit Sword
  • Spirit Excalibur
• Time-Skip
• Power Up
• Dragon Dash
• Portal Creation
• Dimensional Transportation
• The list goes on!

Wiz: It can't be sugarcoated that these avatars are able to learn such techniques, but it's also part of the game itself as part of their kit for them to use.

Boomstick: Sort of like storing up a lot of food in your fridge for a huge party! It may seem like a lot, but you'd still try to get everything you need!

Wiz: Each avatar can learn certain skills, depending if they can actually do so or not. But in a general sense, Note is able to use flight, energy blasts, and weaponized ki. Ki is the Dragon Ball equivalent of one's own life energy, and with it, she can learn moves such as the Kamehameha, the Galick Gun, and even the Absolute Release Ball.

Boomstick: On the battlefield, she's a pretty smart fighter that can recognize what's about to happen and can act on it within a small time frame. This is like the Time-Skip, where time freezes around her so that she can get a massive combo in within half a second.

Pop-Up Note: The Time-Skip also creates a pocket dimension where the user can't be touched and can only be countered by an opposing force's overflowing ki, a faster reaction time, or both.

Wiz: She can also use moves such as the Dragon Fist, which unleashes a dragon-like fist and decimates the opponent to smithereens, the Omega Blaster, which fires a small energy bomb that can be intensely increased as more energy gets fueled into it, and the Spirit Bomb, a sphere that fires a massive blast full of the energy of all surrounding life. Though this move only effects those without a pure heart, it can still be absorbed and use it to their handling.

Boomstick: There are also other stuff that she can learn, such as the Sphere of Destruction, a powerful energy blast that could wipe out planets! A blast like that would have to take at least 60 yottatons of TNT per planet.

Wiz: This is also the same Beerus whose fisticuff clash with Super Saiyan God Goku shook the entirety of Universe 7 in seconds! For the record, our own observable universe is around 93 billion light-years across, and the Dragon Ball universe is about 9 to 13x bigger than that, so he would have to be hitting at a rate of 240 quadrillion times faster than light!

Pop-Up Note: Beat and Note have shown to have similar feats, considering that they've been in many trailers together and have even proven to be on equal footing from time to time.

Boomstick: And you think that by now, these avatars can learn every move in the book, right? Don't count on it! There ARE limits to what can and can't be learned. Kind of sucks since you wanted to have that one thing, but you can't have it because you're not allowed to!

Wiz: Kind of like when you weren't allowed to have DUMMI test out your beer cannon for the sake of "science" because of the new rules that were put into place last month?

Boomstick: Hey, I was trying to test out how far he can shoot out beer from his head! Not my fault that the can in his head had uses for shooting shit!

(Cue Music: Extra Stage)

Wiz: Uh-huh. Tell that to the janitor. Anyways, Note's wide variety of moves are ridiculous to count, but remember: this isn't the only method of fighting that she uses to get the job done. Thanks to her duties in the Time Patrol, she's also weaponized some of the game's various weaponry.

WEAPONS

• Dragon Ball Heroes cards
  • Summon characters and use their abilities
  • Fight alongside them
• Hero Switch
  • Allows entry into Dragon Ball Heroes
  • Able to summon cards
  • Notable supports: Damage Boost Unit, Attack Units, Team Buffs
• Super Hero Robo
  • Allows different modules for battle
• Accessory items
  • Access to Paparapapa Magic
    • Reduces stamina and energy
• Key Sword
  • Full Charge Form awakened by Chronoa
  • Purifies dark magic
  • Can seal people into the Time Labyrinth
  • Nullifies a person's power

Boomstick: As we brought up before, she can use the Dragon Ball Heroes cards to summon characters and have them fight alongside her. It's weaponized gacha at its finest, but they can also grant stat boosts and enemy nerfs so that they could retain their energy.

Wiz: And like other Heroes, she also uses the Super Hero Robo, a moving robot that stores modules that also have stat boosts and enemy nerfs. This can also have its own set of weapons such as rockets and a shield to help the team out, as well as scan an enemy for their data and retrieve their data.

Boomstick: She also carries with her the Hero Switch, a bracelet funded by Xeno Trunks that lets her enter the game and use her avatar both in and out of her own world! She can also use this to summon the card characters faster and time travel more efficiently!

Wiz: With the help of these cards, she can also manage to rip apart time and reality to create portals and summon characters such as Great Ape Goku, Jiren, and even Hirudegarn! Depending on how much energy she has left, she can even send her foes away into other dimensions and fight there.

Boomstick: But sometimes, summons aren't enough to get the job done. The heroes can also use the Key Sword, aka the most demon ex-machina thing you've ever seen in your life! By harnessing its power, it can completely shut down a person's abilities and lock them in place for a time, as well as manipulate and weaponize RNG.

Pop-up Note: Though the avatars themselves haven't used these in the trailers, it's still used in the arcade game during the Charge Impact portion of battles. And even though it's only for costume purposes, they can also hold Trunks's sword and other famous weapons.

Wiz: This is similar to how the Key Sword was the ultimate endgame weapon to finish off Mechikabura, a foe who consumed the infinite multiverse within a black hole known as the Chaos Ball. The power of a normal black hole would be around 100 billion times as much energy as the sun, so by using that logic to calculate the power of the Chaos Ball and its infinite power, it must have yielding a force of at least 20 tenaFOE of force, enough to destroy entire galaxies without even trying!

Boomstick: And the Key Sword was just the ultimate "No U" trump card for Trunks to slice him into dark sashimi! Even Super Saiyan 4 Xeno Vegetto had trouble with the Dark King, but this just killed him in 1 shot! Simple as that!

Wiz: All of these abilities and summons were suited to help Note in battle, but there was one thing that needs to be discussed that had a lot of fans talking. By tapping into her pure rage and Saiyan power, she can be able to assume the golden form of the Super Saiyan!

(Cue Music: Raging Blast)

TRANSFORMATIONS

• Super Saiyan - Unlocked by primal rage
  • x50 multiplier to base form
• Super Saiyan 2 - Unlocked by Class-Up
  • x2 multiplier to Super Saiyan
• Super Saiyan 3 - Unlocked by Super Class-Up
  • x3 multiplier to Super Saiyan 2
• Super Saiyan God - Unlocked by God Class-Up
  • x~200,000 multiplier to Super Saiyan 3
• Super Saiyan Blue - Unlocked by Super God Class-Up
  • x50 multiplier to Super Saiyan God
• Ultra Instinct Sign - Unlocked by Ultimate Class-Up (Sign Style)
  • x60 multiplier to Super Saiyan Blue
• Super Saiyan 4 - Unlocked by Ultimate Class-Up (Full Power Style)
  • x10 multiplier to Super Saiyan 3
    • Also able to use Super Full Power Saiyan 4 Limit Breaker
      • x~20,000 multiplier to Super Saiyan 4

Boomstick: That's right! Note was the first female in Dragon Ball history to ever transform into a Super Saiyan! We have officially entered a new era in Super Saiyan gender equality!

Wiz: In the official Dragon Ball Daizenshuu, each Super Saiyan form is stronger than the previous one with a set multiplier for each form. And to unlock this, Note uses her Class-Ups, which may look like she's only swapping outfits, but it allows her to use these transformations. In the 5th Big Bang Mission trailer, it's shown that the Saiyan avatars can even transform without needing the Class-Ups.

Pop-Up Note: It's implied during that same trailer that she's able to utilize Saiyan beyond God, which lets her use god ki while in her base form. The multiplier for Saiyan beyond is similar to Super Saiyan 4, but also adds at least a x4,000 multiplier to his other forms, making her as powerful as she was as a Super Saiyan God.

Boomstick: And it's not just the normal Super Saiyan transformations that she can access. She can also transform beyond! From 2 to 4 and even the god forms! heck, she even figured out how to access Ultra Instinct! If that hasn't shown how much she's become a history maker to younger fans, then I don't know what does!

Wiz: As both a technique and a transformation, it allows a person's limits to break beyond and fight with their emotions on the drive, mostly. This is how Goku was able to use this while in the Tournament of Power to shake the entire Null Realm and create these entire galaxy-like particles. Assuming that this is similar to the Milky Way without stars or planets and the size of the energy itself, we can determine that Goku's Ultra Instinct must have been exhaling a mass of over 150 kiloFOE of force!

Boomstick: That's enough power to create even the smallest of universe, and it just shook the entire pit of nothingness like it was a huge empty box of crackers!

(Cue Music: Kiseki No Honô Yo Moeagare!!)

Wiz: Tapping into divine ki is pretty hard at first, but using the power of video game logic allows her to do this more efficiently. She even managed to perfect this divine ki mastery with the Universal 7 Angel, Whis, who can move at around 40 quintillion times faster than light.

Boomstick: Yeah, I can only imagine how hoard it would be to even hold such power, even when you're not able to drive yet.

Wiz: And it didn't take until several years later in the Dragon Ball Super anime that a female Super Saiyan would finally be canonized thanks to Caulfila.

Boomstick: But hey! At least Note can say that she got there first anyways!

Wiz: But don't confuse pride over strength, unlike Vegeta. Note has shown to have as much courage as her superiors have. She's even taken hits from some of Dragon Ball's most infamous villains such as Majin Buu, the God of Destruction avatars, and even Fu.

FEATS

• Became a Dragon Ball Heroes master
• Joined the Time Patrol to save the Xenoverse from the shattering of time
• Trained with Whis
• Traveled across Dragon Ball, DBZ, GT & Super
• Became the co-mascot of Super Dragon Ball Heroes
• Took 2 Kamehamehas point blank
• Defeated Nico, Xeno Turles, Kid Buu, Caulifla, Kale, Demigra, Chamel, Sealas

Boomstick: She's gone toe-to-toe with some of the strongest fighters in the competitive Heroes scene, became one of the top leaders of the Dragon Ball Heroes team, and even took not 1, but 2 Kamehamehas to the face!

Wiz: Thanks to her efforts, she and her friends were noticed and even recruited by the Time Patrol, a history-preserving agency that have insane powers in their own rights, such as their version of Goku being able to shake multiple timelines from his base energy and even Xeno Trunks, who can move around the entire Dragon Ball Xenoverse over several septillions of times over!

Boomstick: And even if she prefers being a smartass over barging in like crazy, she can still get some heavy punches in thanks to the help of her friends. Hell, she's even managed to form a relationship with Beat and haven't been separated since!

Wiz: She's proven to take on some of Dragon Ball's biggest villains such as Demigra, Majin Buu, Turles, Demigra, and even a version of the Demon God Hero, Chamel. Chamel's mere existence caused the entire multiverse to collapse and, depending on which avatar is selected, had to put up a fight that had to be taken into space.

Boomstick: But even with all of this power, there also has to be some form of tradeoff for everything, like with all things.

Wiz: Even with her Saiyan biology, she can't exactly breathe in space and she can still be damaged as if she was in the real world and enough of said damage could take her out action.

Boomstick: Even if she's had more years of being the Saiyan Heroine, she's not immune to mistakes. Her overconfidence and competitive nature had lead her losing more matches and she's even taken harsher hits because of it... like, really harsh.

Wiz: And it doesn't help that she's still a young warrior, so she's still got some self-reflection to do, like how she tried to rush in and attack the God of Destruction avatars without figuring out who they were first. One of them was the Destroyer Hero, Shandy, who, as well as Note and other avatars, can use the Super Star Break ability to summon a massive ball of energy with a force of at least 250 exatons of TNT.

Pop-Up Note: The Super Star Break and the Sphere of Destruction have shown to be similar in power, and it could be possible that with enough energy forced in, they could outmatch each other.

Boomstick: Note may be challenging herself way too much, but that's not to say that she's a bad person. She does wish for good things to happen and is willing to do anything she can to see it through.

Wiz: She's even managed to survive a ki blast from Broly which knocked her out and made her switch out of her avatar form to her human form and was still able to get back up just a few moments later. What could have potentially killed her only added fuel to the fire. So it's surprising to see how far these avatars can actually hold themselves in battle. She's even helped Beat and Xeno Gogeta fight off the menace known as Sealas before he could alter and conquer time itself.

Boomstick: She's come a long way of being someone who only wanted to be the best out of anyone, and she's even noticed it herself.

Wiz: Well, that's called character development.

Boomstick: Yeah, Beat was right to have the Saiyan Heroine by his side. No matter the cost, Note will always find a way to bring good and justice to the world around her!

Note: This might not be the most "Time Patroller" thing to say, but I kinda liked this anomaly. It gave us a glimpse into a GOOD future for once.

Kairi Dream Drops Into DEATH BATTLE!

(Cue Music: Kairi's Theme)

Wiz: Once upon a time, there was a kingdom known as the Radiant Garden. A capital of light that connected throughout several worlds and where fairytales come to life.

Boomstick: Ruled by the sage-king, Ansem the Wise, this peaceful land had only known peace and prosperity with its people learning to cooperate and live in harmony.

Wiz: To them, it was heaven. But to the roots of evil, it was to be their new stomping grounds.

Boomstick: So one day, these embodiments of negative emotions called the Unversed rolled into town and wrecked shop on everything around it. Man, talk about a bad day rolling into town.

Wiz: And one of the kingdom's denizens, Kairi, was unlucky enough to be chased down by them. But after a chance encounter with Aqua and King Mickey (don't worry, we'll get to that in a bit), she had her hands on a Keyblade, a mysterious weapon powered by the light to defeat the darkness. And once she was saved, she was gifted a charm that would let the light protect her.

Boomstick: This is kind of heavy stuff for a game series filled with Disney characters, ain't it?

Pop-Up Note: When Kairi touched Aqua's Keyblade, she accidentally performed the Keyblade Inheritance Ceremony, in which a Keyblade Master chooses someone righteous of heart to wield a Keyblade.

Wiz: This isn't even the end of it. A year later, her home would be shrouded with darkness and Kairi was kidnapped and manipulated by Xehanort, under the belief that she was one of the Princesses of Hearts, tricking her into thinking that her kingdom was falling into darkness, with the promise of an experiment to save everyone.

Boomstick: Well, her grandma should have told her about stranger danger during story time because that experiment turned out to have erased her memories of her home and cause the newly-named Hollow Bastion to go full goth mode. Really sensing some red flags right now.

BACKGROUND

• Gender: Female
• Age: 16
• Birthplace: Radiant Garden
• Friends: Sora, Riku
• Wielder of the Destiny's Embrace
• One of the Princesses of Hearts and of the New Seven Hearts
• Bearer of Naminé's persona
• Hair styles are inspired by Utada Hikaru

Wiz: After being adopted by some mayor, almost a whole decade would pass without any sort of hassle. In that time, Kairi would befriend two other people named Sora and Riku. They would spend their time playing together and relaxing on the beach. That was until one day, before setting sail to explore new worlds, their home was attacked by the Heartless.

(Cue Music: Scala Ad Caelum)

Boomstick: The embodiment of a people's dark energy. Kind of like someone's shittier side of a split personality, but humanized.

Wiz: These Heartless destroyed the home that they had preserved, taking Riku into the storm by force and making Sora and Kairi run to shelter.

Boomstick: They tried to hide for as long as they can, but Kairi was swept away anyways and separated from her friends. And if that wasn't enough, her heart chose Sora as a vessel and was left behind when she went missing.

Wiz: It took until her spirit helped Sora unlock her memories and guide both him and his friends to bring her back. Sora had to sacrifice his heart to bring her back, but in return, this separated them once more.

Boomstick: Man, she just can't catch a break, can she? Even when she DID find him again, this weird guy named Ansem drove them apart and their entire worlds began to fall apart. But once Sora saved the day, she was sent back to Destiny Islands in hopes of awaiting for their return. Oh, and this girl named Naminé was selected to fix the problem, but it led to even more complications, especially with Roxas showing up to make things more confusing, like the series itself.

Wiz: But tired of waiting around, Kairi decided to send a bottled letter out to sea and step out of her home to finally find him herself. Thanks to Roxas confusing her with Naminé, this helped restore her memories of Sora and brought about her new flame.

Pop-Up Note: Though Kairi and Roxas have only ever interacted once, simply talking to Roxas was the key to restoring Kairi's memories of Sora.

Boomstick: And being a Keyblade user, she's equipped with some of the biggest magic out there to defend herself.

Wiz: After a trip to The World That Never Was, Riku would bestow this weapon forged from the Real, of Light to Kairi as means of defending herself in battle, like Sora.

Boomstick: And lucky for her, Keyblade isn't just able to combat the darkness with the light. This was a special one that was given to her to weaponize light and keep her safe.

ABILITIES AND TECHNIQUES

• Gliding
• Super strength
• Barrier creation
• Manipulation abilities
• Magic Abilities
  • Firaga (Fire Magic)
  • Blizzaga (Ice Magic)
  • Thundaga (Thunder Magic)
  • Aeroga (Wind Magic)
  • Curaga (Healing Magic)
• Physical Abilities
  • Spiral Bloom
  • Blitz
• Team Abilities
  • One Heart
• Other Abilities
  • Flower Shoot
  • Seven Wishes aura
  • Starcracker
  • Resurrection
  • One Heart

Wiz: She was given the Destiny's Embrace, a Keyblade that allows her to trample past the Darkness with the power of the light. She can create barriers, increase her own abilities, shoot energy spheres, and even slash at opponents at various angles.

Boomstick: She can keep up with other Keyblade users such as Riku and Sora, both of whom can can effortlessly dodge lasers and reflect hundreds of blasts coming at them like bullets.

Wiz: it should be noted that Roxas once used his heart to travel from the Radiant Garden to the Keyblade Graveyard in seconds. The Kingdom Hearts universe is comprised of several star systems, so in order for him to get from Point A to Point B in that amount of time, he'd had to be moving around 170 million times faster than light.

Boomstick: It's also like how guys like Sora and Riku had to parry several magic orbs that were attacking them from every angle, having to move beyond normal reactionary speeds!

Wiz: With her magic, she can shoot fire, freeze people, cast gusts of wind, heal herself from any wounds, and even become immune to corruption. She's even able to use a special aura from the Seven Wishes and can strike with a nonstop barrage.

Pop-Up Note: In the official manga, according to Axel, Kairi is able to travel through the Dark Corridor without any negative effects due to her status as a Princess of Heart.

Boomstick: She can even move past stopped time thanks to the broken powers of being a princess, which was very useful when she went to the Realm of Darkness. It's like being surrounded by a thousand guns, but you have the most broken armor to protect yourself. I would know. I tried that once.

Wiz: You mean the one time where you pissed off those robbers when you were on a road rage while drunk-

Boomstick: SHUSH! We don't tell that story...

(Cue Music: Dark Domination)

Pop-Up Note: As a Princess of Heart, she can also combine her light with the other princesses to open the Final Keyhole, a seal that holds the power of the entire universe.

Wiz: Wellll, she can also manipulate other people's power, either upgrading them to a higher level or even turn it against them. She also wields keen sensing of nearby Darkness so that she can prepare for where they can strike at.

Boomstick: There's also this weird thing that she can do that can restore a person's body and even resurrect them after they were consumed by Darkness, but this might be because of the shared connection that they have together.

Wiz: But she's also got her charm that was bestowed to her by Aqua that allows her to travel to another being of light. It was this exact charm that led Kairi to Destiny Islands in the first place.

Boomstick: It also acts as a last resort for when she's in real danger, she can extract their hearts and give it to another person worthy of the mantle.

Pop-Up Note: The purity of her heart also grants her abilities to keep darkness away or hold it back temporarily, something that comes natural to the Princesses of Hearts merely by being in presence. The greater the number of Princesses gathered, the more effective this skill is.

Wiz: Not that she would need it because she's also efficient with kendo, a fighting style that deals with fighting with a weapon like the Destiny's Embrace. Keyblade users can also summon their Keyblades back to their hands like normally! Either that or just use her hands every once in a while.

Boomstick: Really starting to find some workarounds with that nervous narrative, huh?

Wiz: Well, she is able to keep up with reality benders, so what do you have in mind?

Boomstick: I'm not trying to start anything. Though, I will point out that she's a bit of a fast learner when it comes to using weaponry.

PRINCESS OF HEART

• Darkness nullification
• Power manipulation
• Corruption immunity
• Access to Kingdom Hearts

Wiz: The princess has also used her abilities to pull off unreal abilities, such as being able to gain access to Kingdom Hearts, a heart-shaped moon that holds the power of the entire multiverse.

Boomstick: Xehanort once used this power to shoot multiple lasers and even harness its energy to power the Darkness.

Wiz: By estimating the size of this moon and comparing it to our own, the energy of Kingdom Hearts must have been carrying around 110 yottatons of force, or about 110 petatons of TNT, more than enough for Xehanort to use for the taking!

Boomstick: And other Princesses known throughout the Disney name are able to do these same feats.

Wiz: We do have to specify that despite Kingdom Hearts treating Disney like the important factor throughout its series, the characters from the classic films have shown to be (at most) on par with those warriors... It's weird.

Boomstick: With these awesome powers, Kairi was able to join up with the rest of her friends and formed the Seven Guardians of Light, a ragtag team of Keyblade users to fight off Organization XIII and create the χ-blade before the evil others can!

(Cue Music: Guardians of Light)

Wiz: And one of those members, King Mickey (remember him?), once fought an entire twister of Heartless to form a Demon Twister. Considering the high stack that they were forming, the power that they were condensing, and the exact width of the twister, we can determine it weights in around 75 gigatons of TNT!

Boomstick: Sora was once able to keep up with the Disney counterpart of Hercules, who could throw a whole rock titan worth 1,600 tons into orbit, and his dad, Zeus, could easily move stars! And stars moving in Kingdom Hearts aren't rare either!

Wiz: Though the scale of the Kingdom Hearts universe itself connects through several worlds, Kairi isn't a stranger to this sort of travel.

Boomstick: And she was later trained by Axel so that she could finally be able to stand on her own two feet, right? ... Right?

FEATS

• Joined the Seven Guardians of Light
• Recovered her memories of her time in Radiant Garden
• Take on multiple Heartless on her own
• Trained with Yen Sid, Merlin, Lea, Aqua
• Scales to other Guardians of Light
• Helped with the final battle against Xehanort
• Defeated Terra-Xehanort, Xehanort, her own complex writing

Wiz: She's managed to travel across countless worlds in her times of adventuring, handle some of the toughest Heartless that attack her, and have even trained under the wise words of Yen Sid, who gave her the green light to train under the same heroine who saved her long ago, Aqua.

Boomstick: And after a year-long nap in psychotherapy, she was able to restore her memories of her time in Radiant Garden and even team up with Sora against an Armored Xehanort to help him beat the ACTUAL Xehanort. Yeah, things like that can be really confusing out of context.

Wiz: She's even fast enough to dodge incoming meteors, which, scaling to the models that were used in the fight against Armored Xehanort, were moving at around 10,000 miles per hour. Not only that, but she's also able to dodged lasers, which can move at around 300 times the speed of light.

Boomstick: She can even pull out a special technique that can make Sephiroth seem like a sweetheart in comparison.

Wiz: The One Heart, a technique that allows her to grow angel wings and attack with the feathers of shared memories. With Sora, this effect is doubled and was what helped her overcome these challenges.

Pop-Up Note: In Chinese mythology, a pair of one-eyed birds with only one wing known as Jianjian fly together by acting as one, thus representing husband and wife.

Boomstick: All these feats sound pretty great and all, but there's still one thing that has constantly plagued her: She... has a bit of anxiety when it comes to one-on-one fights.

Wiz: Her magic can't be used so frequently as excessive amounts of magic energy would drain faster, with it being linked to her own energy. And her fear of change has what led her to grow worrisome of what could happen to her friends. In her mind, she only wants to remain on Destiny Islands and be with Sora and Riku once again... But mostly Sora. Why did you think we keep bringing him up so many times?

Boomstick: It also doesn't help that she gets either captured or separated from her friends like... ALL THE DAMN TIME! It's not even funny! Hell, this how Xehanort actually killed her and turned her into crystal fragments, so Sora had to pull out some time travel bullshit and revive her again.

Wiz: Time Travel does have its heavy costs, but for Sora, he needed to restore what he cared for most or else both of them would have ceased to exist.

Boomstick: What a nice guy. Though, Kairi may be a little too attached. Like, WAAAAAAY too attached. In more ways than one.

Wiz: But despite her shortcomings, she's determined to save her friends and bring peace to the realm that she's a part of. Even if it means having to travel to the end of time, she'll always pull through with the light. She's come a long way from giving flowers to being given her own.

Boomstick: But until then, she'll hope that one day, she and Sora will reunite once and for all and return home to finally live out that Happily Ever After ending...

(Music fades.)

Boomstick: Oh, and Riku as well, but we don't have enough time to stretch out the "Kairi's writing is bad" jokes, so we'll just leave it at that.

(Sora and Kairi summon their Keyblades into their battle against Armored Xehanort,)

Kairi: I can do this!

Closing Statements

(Cue Music: Wiz and Boomstick)

Wiz: Alright, the combatants are set, and we've run the data through all possibilities!

Boomstick: It's time for a DEATH BATTLLLLLLLLLLLLLLLLLLLLE!!!

The Fight

(Cue Music: Keyblade Graveyard)

The scene takes its first transition to the Keyblade Graveyard late at night. This was known to be home to the fallen souls of the Keyblade War. But here, there was a wondering living being that was searching everywhere for something, or more specifically, someone.

This is one of the Princesses of Heart, Kairi. She was looking for Sora once again, and she had recently put herself in a deep sleep for a whole year to find some clues. After some complicated stuff, she was able to show up here to figure out if there was something that could help her.

Kairi: Darn it, Sora... Where are you?

That's when she would feel a slight breeze in the barren air. Kairi would look up in the air to see a bunch of lightning would surround a semi-transparent dust tornado forming. The Keyblade user would stand her ground as she prepared for what's about to appear.

The tornado would die out to reveal the Saiyan Heroine, Note, floating in the air and being in a relaxed posture. She was holding her cell phone near her ear and talking her boyfriend, Beat, without looking at Kairi.

Note: Look, I get it. I know that Super's Goku could possibly be more powerful, but hear me out. GT Goku is essentially what-

Kairi: Uhhh... Hello?

Note would overhear Kairi's words and noticed her from below.

Note: Beat, babe. I'm gonna have to call you back. Something just came up. Love ya, bye.

She hung up her phone and put it in her pocket so that she can float down and stand parallel to Kairi.

Kairi: Who are you? And how did you even get here?

Note: Oh, me? The name's Note. The Saiyan Heroine herself. One of the best SDBH players of all time. Yada yada yada...

Kairi: Oh, it's... nice to meet you. I'm Kairi! I was just looking for a friend of mine!

Note: Well, I'm sorry to say this, but that's gonna have to be put on hold for a while cause I'm gonna have to arrest you.

(Record scratch.)

Kairi was taken aback with what Note just said. She hasn't even known her for a minute and she already wants to arrest her?!

Kairi: Wait, what for?!

Note: Well, your constant movement from one world to the next was noticed by the Time Patrol and it was NOT taken very lightly. So save your rescue mission for later because you're coming with me!

Kairi: H-hold on! Can't we just talk about thi-

Note would try to throw a ki blast to Kairi's face, but the Keyblade user would quickly move out of the way to avoid the blast taking her head off. This would then prompt Kairi to summon her Destiny's Embrace Keyblade and defend herself.

(Cue Music: ULTRA Super Gogeta Theme)

Kairi: That was fast! I couldn't even see it coming!

Note: I said you're coming with me. Whether you like it... or not.

Note would take a fighting stance as she prepared to kick this target's ass for unsanctioned world hopping. Whether it be through clean or hurtful tactics, she's not gonna let this person fall from her grip.

F I G H T !

Note would charge her aura and flew towards Kairi, who would swing her Keyblade at Note's face. She would try to get more swings to try and close the gap early. But Note would manage to dodge them all and let out a massive punch to her gut. She would let out several more punches at her and caused the princess to be pushed back.

Note would kick her to a nearby boulder before holding another ki blast and threw it at her, but Kairi would use this to her advantage. She would plant her feet onto the boulder and jumped away from the incoming blast, making the object crumble upon impact.

As Kairi made her sidestep, Note appeared behind her and grabbed her arm to reel her in for a punch to her face. She would then rush her down with several strikes to keep her cornered. She would then finish off the combo by grabbing head and delivering a knee strike to the face before adding in a Kiai wave to push her away. Kairi would collapse on the floor as she was already being taken to her limit.

Note: Is this all you got? Come on, you can do better than that!

Kairi would slowly get back and gripped her Keyblade close to her.

Kairi: You haven't seen anything yet!

The Princess of Heart would step up and let forward several swings of her Keyblade, which took the Saiyan Heroine by surprise as she would try to dodge the swings coming at her back and forth. That's when Kairi spin kicked Note's face around so that she could swing her blade at Note. Each swing made her step back as Kairi would use a Blitz to send her into the sky.

Note would catch herself and fired several ki blasts towards the princess, but she would dodge all of them as they were quickly and run across the rocky field.

(Cue Music: Xehanort Clones)

Kairi: Thunder!

She would shoot out her Thundaga spell to shoot out lightning and tried to hit her opponent for it. Note would try to block it, but the electricity would bring her down to the floor. As she was crashing down, the Keyblade user would catch up and fire a Flower Shoot at her, hitting Note in the back and sending her away.

Kairi would catch up to Note and kneel down towards her.

Kairi: I really don't want to do this, but you were just being rude! Sorry!

As Kairi swung her weapon towards Note's head, she would take notice and open her now-emerald green eyes and burst with a bright yellow aura. To the surprise of Kairi, Note's hair had turned from black to yellow, and her flowing ponytail has proven this.

Note: Don't apologize. That was simply a warmup!

Note would vanish into thin air and reappear to punch Kairi rapidly, as well as adding some elbow strikes to her face. She would then use a Kiai to push her away and deliver a dropkick her to the floor and cause a crater to form.

Kairi: I need to think fast. She's got be cornered at every turn... I've gotta find a way to keep up with her speed. Perhaps-

Looking down on the dust cloud that had formed from the attack, she would see Kairi firing away with more Thundagas towards the Super Saiyan. Note would see this coming and deflected some of them with her bare hands.

The Saiyan Heroine would fly forwards and attempted a massive punch to the face, but Kairi blocked her fist with her Keyblade in time. They would jump away from each other, with Note bringing her Spirit Sword, and lunge back to swing their weapons at one another. The sounds of clanging would be heard throughout the crater as these girls kept on letting their swords to the talking.

Note tried a downwards swing, but Kairi would block it easily and shoved her with a shoulder block. Note would retort with a pump kick before sizing up her Energy Flash to push her away.

Note: Galick Gun!!

Note fired off the Galick Gun to combo off her Energy Flash, but Kairi would form a barrier to quickly block herself from the incoming blast. She was being pushed back by the blasts's force, but she wasn't gonna give up yet. She would sense Note coming her way and decided to fire a light beam to get her away, which managed to work once it was seen.

(Cue Music: The Encounter)

Kairi would then fly upwards and have a massive aura surrounding her. She would begin to harness the power of the Princesses of Heart as she gained a bright aura around her. She would then fire off several explosive orbs via Heart of a Princess at Note's direction.

Note: Oh shit!

Note would take to the skies as well as she would try to avoid every orb that came her way. In the background, several orbs would explode and cause several fallen Keyblades planted onto the ground to disintegrate into ashes. Looking back at this, Note realized what her next plan should be.

Note: If you really want to step things up... Then I'll just pull something of my own!

Note would reach to her pockets and bring out a Dragon Ball Heroes card pack to her hand. Continuing to dodge the orbs, she would unpack the booster pack and see her cards that she pulled, much to her delight.

Note: Perfect. HA!!

The Time Patroller would throw her cards and use her Hero Switch to summon forth her 3 pulled characters. From the bright lights came forth Super Saiyan Bardock, Ultimate Gohan, and Beerus. Her and her team would dash forward and dodged several of the orbs that were coming her way.

Then, they would charge up different ki attacks: Bardock had his Final Riot Javelin, Beerus had his Wrath of the God of Destruction, Gohan had his Masenko, and Note, cupping her hands to form a blue energy sphere, had her...

Note: KAMEHAME... HAAAAAAA!!!

Thrusting their blasts forward, Note led her Super Kamehameha with the others' attacks to fire directly at Kairi. The Keyblade warrior saw their combined energy blast coming towards her, she she decided to form another barrier and block it. But as soon as she managed to get it in time, the barrier was beginning to crack due to the high pressure of the blast affecting it.

Kairi: Not this time! Starcracker!!

Kairi would quickly let her shield break and fired a massive light beam towards her adversaries. This managed to overpower the combined blasts completely and take out the images of the characters Note had summoned in quick succession.

Note, on the other hand, was trying to push the Starcracker back as much as she can. However, she felt her energy becoming more weaker and weaker by the minute. Realizing what she's in right now, she needed to boost into a new level.

Note: TCH!

(Cue Music: Kami's Lookout)

Seemingly letting herself be absorbed into the blast, a bright blue flame would emerge as Note would Dragon Dash as a Super Saiyan Blue and zoom straight towards Kairi. She would give her a massive sucker punch to the face and chase her down to combo her with punches and kicks. She would drag her around the sky as she would cause the princess to fall victim to her fists.

Note: What's wrong? Still trying to keep up?

Note would then return to the ground and fire a massive God Slicer from her hands, which causes Kairi to be sent through a small mountaintop. The Saiyan Heroine watched on as her godly aura waited for her to make the next move.

That's when she sensed Kairi's magic flaring up as the mountaintop would suddenly explode and have a bunch of debris fall to the ground.

Kairi: LET'S RIDE THE WIND!!

Kairi would then use her Aeroga spell to cast a massive wind vortex to spin towards Note. This caused the cerulean Super Saiyan God to be swept off her feat and be taken by the vortex. This didn't get to her, however, as she would let this be used to her advantage to try and get to Kairi.

(Cue Music: Burnin' Up)

The Princess of Heart and the Saiyan Heroine would meet up again to once again clash with several different attacks that would be heard all around the vortex. With the Destiny's Embrace and the now-Spirit Excalibur clashing together, they were just trying to land a good hit in at every angle.

Note would try to swing at her abdomen, but Kairi would retort it with several Blitzes as means of defending herself. Note would soon fly away and hold a massive dark ball of energy.

Note: Eat this! Absolute Release Ball!

Note would throw her Absolute Release Ball towards her opponent, but...

Kairi: Freeze!

Kairi would use her Blizzaga to throw massive shards of ice and cause it to explode. As the explosion took affect, Note teleported above Kairi and double axe handled her to a nearby plateau.

This would cause the wind vortex to disperse away and Note would once again go after the Princess of Heart. She would then see her crashing onto the rocky floor with bruises around her everywhere. She was trying to get back up, but she wasn't feeling anything that could help her case whatsoever. The Saiyan Heroine would land a few feet across her and slowly walked up to her.

Note: You done yet, Kairi? I suggest giving up while you can. You put up a good fight, but you're nowhere near my level...

Kairi would look down on the ground and see that droplets of her blood, sweat, and probably tears were pouring from her face. She was pretty much defeated. She couldn't do it anymore. She was down for the count.

What would Riku do, she thought? What would my friends think...? What would Sora think?

That's when it hit her like a head. Her friends... She can't stop now. She's come this far trying to find Sora and some time traveling warrior wasn't going to be the end of her road. She would then look up towards the Saiyan and gave a determined look.

Kairi: Not yet... I'm not done yet...!

Note: Still going, eh?

(Cue Music: Unbreakable Chains)

With a glowing green aura around her, she would slowly heal herself from her wounds with Curaga and stood up to confront her. The moon was also shining bright behind her. But this wasn't just any moon...

Kairi: I'm a guardian of the light... A Princess of Heart... I will not back down from this battle... All I need... IS THE LIGHT!!

She would raise her Keyblade towards the night sky and let out a mighty cry for her second wing of power.

Kairi: COME! KINGDOM HEARTS!!

Kairi would suddenly have the Kingdom Hearts moon glow and surround her with a bright sphere with the Kingdom Hearts emblem. Embedding her with the light, Kairi would be fully recovered as Note locked on in shock.

Time was wasting, she thought. So she decided that now was a good time to end this quickly and bring out her Key Sword to even the odds. The two girls would soon clash towards one another as they would use their weapons to try and shed some blood.

Wherever Note tried to swing at, Kairi was always there to block it. She would try to go for a swing up in the air, but Kairi would block up and gave her a knee strike to send her backwards.

The princess would then shoot out several fireballs thanks to her Firaga, much of which were aiming towards Note at an alarming rate. Thankfully, she used her sword to block the fire from hitting her, but she wasn't given enough time to be hit by the Keyblade once more. They would soon meet once again as Kairi would go for another Blitz, but...

Note: BIG BANG ATTACK!!

Note would react just in time to use her Big Bang Attack and fire at Kairi with a massive ball of energy. This was enough to get her away and keep a distance for now.

Kairi: She can keep going even after I used this much power... She needs to be stopped!

After being blasted away, Kairi would then use the aura of her Seven Wishes to strike Note at multiple angles and giving her several cuts of blood. She would continue this until she would use another Starcracker to fire a light beam towards Note. This would send her plummeting downwards to the near-edge of a cliff.

The Saiyan Heroine was wounded from head to toe as she would stare upon what the Keyblade girl was gonna do next.

Kairi: Nice try, Note. But I've been through so much my entire life, and I won't let today be the end of my journey! I'll take you down, not just me... but for my friends!

She would then use her One Heart ability to grow a pair of angel wings and charged up the tip of her Destiny's Embrace one more time. Launching forward, she would zoom her way towards Note and held her Keyblade directly towards her opponent and dived headfirst with the feathers of her memories fueling her.

Mere seconds before Kairi would plant her target six feet under, Note would seemingly close her eyes and let the inevitable hit her, but as fate would have it...

Note: Funny... You're not the only one... who fights for their friends...

Note would open her eyes to reveal a silver color in her iris and a bright light would consume the entire cliff, causing it and the surrounding landscape to explode and die away. As it would die down, Kairi would rub her eyes to regain her vision and see if she was able to get the hit. But as she found out, Note managed to catch it with one whole finger. But to make things more weirder, it seems like she was back to her base form, but at the same time... this was something new.

Note had tapped into her trump card transformation: Ultra Instinct. Kairi would try to wiggle her Keyblade free from her grasp, but Note wasn't letting it or her move a single bit.

(Cue Music: Fierce Battle Against A Mighty Foe)

Kairi: W-what is this?!

Note: You may be a Princess of Heart, Kairi, but you're forgetting one thing.

Note would immediately use her Time Skip technique to deliver a stiff elbow to Kairi's face within the half-second space before grabbing her arm.

Note: I'm the Saiyan fucking Heroine.

Note would continue to use her Time Skip technique to rapidly rush Kairi with a barrage of rush attacks that would make her aura begin to wear down by the millisecond. Each strike, she would strike her and her magic was starting to become more drained as it couldn't handle this much of Ultra Instinct's raw power.

Kairi would see Note go for another attack, so she would swing for the fences and swing her Keyblade to Note's face. But the Saiyan Heroine managed to dodge it without even needing to think of a reaction. Bringing back her Key Sword, she would let forth an upward slash and slice the Destiny's Embrace in half.

The princess was in complete shock to see the weapon that was given to her with the power of the light shatter right in front of her eyes. But Note would stop her time to process what had happened by kicking her abdomen and launching her into the air. She would then rush her with several more strikes, but she would use her sword to attack. It was Kairi's turn to bleed once more and Note was not letting up.

As the Saiyan Heroine would appear from above the clouds, she would hold her hands out and exhert a massive blue ball in her hands...

Note: TAKE THIS!! BIG BANG KAMEHAMEHA!!

Note would fire a massive Big Bang Kamehameha and engulf Kairi in its wake. Kairi would try to shield it with her One Heart wings, but the energy pouring out from Note's attack kept on growing and made her magic become more down. Eventually, her wings gave in and shattered, causing Kairi to fall victim and let the screen go white, as with when defeating a boss in the Kingdom Hearts series.

The blast would land onto the ground and erupt with a massive explosion and made the whole environment rumble from their whole fight.

A few seconds to let the smoke die down would pass by, and Note saw that Kairi was on her knees, having managed to somehow survive the Big Bang Kamehameha. The Princess of Heart was trying to hold her body together to continue fighting.

Kairi: I... can still... go on...

Note: Let's test that.

Note would soon summon several more Key Swords to her possession and threw all of them at different parts of Kairi's body. From her arms to hew stomach and to her knees, each one would zoom through her skin and cause several holes to make her bleed buckets. She was yelping in agony as all of them would make her lose consciousness.

Kairi: Agh... agh....

Note: You were quite the fighter, princess. But don't worry a single bit...

The Key Swords would suddenly be brought back to Note's hand, but they would cluster together and begin turning into one. This would make the Awakened Key Sword be chained around her hand as she gave her one last mean look.

(Cue Music: Goku's Anger)

Note: This'll only last for a second... HAAAH!!

The Time Patroller would throw her weapon like a discus as a bloodied Kairi, on her last gasp, would look towards the incoming Awakened Key Sword and stick out her hand, weakened to even move due to her injuries.

Kairi: NO-!

The Sword would impale her hand and mouth and enter through her torso, making her entire body be split into 3 parts. Blood splatter upon impact and her eyes would immediately go blank. A massive burst of energy would shoot from the Key Sword and disbursed Kairi's now-nullified powers into a beam of light, shooting into the sky for a brief few seconds. As it died down, the wind would blow with dust as the Key Sword would disappear.

Note, reverting back to her base form, would fly down next to the blood-heaped princess and tapped the back of her head to get some sort of answer. That's when her body would slowly fall forward and her head would go right through the tipper point of a broken Keyblade stuck in the floor.

With Kairi's body and brains turned into mush, Note would wince at what had just happened and stepped away from the damage, realizing the severity of this battle's ending.

Note: Aaaaaaand there goes that paycheck... Shit, uhh... Sorry about that-

Shrugging nervously, Note would activate her Hero Switch to teleport back to her own world, leaving Kairi's impaled head and bloodied corpse to rot in the Keyblade Graveyard as the Princess of Heart's days of heroism are officially over.

K O !

(Ending A: Returning to her own world and form, Note would be met by Beat. She gave him a hug and a kiss on the lips as they made their way to the arcade to play a few rounds of SDBH, trying to hide what had happened in her recent mission.)

(Ending B: Kairi's powers and Heart would disintegrate into dust out of her body as her heart and soul faded away like pixie dust. Her deceased corpse is what remained within the Keyblade Graveyard.)

Results

(Cue Music: Boogie Back)

Boomstick: Quick! Someone get Yen Sid on the phone! Now the guardians' got 2 search parties to take care of!

Wiz: Armed with the power and might of Destiny's Embrace, Kairi may have handled some heavy experiences dealing with stronger opponents thanks to her magic, combos, and power distribution, but Note basically triumphed over everything else. More specifically, she was more capable of keeping herself in check both in battle and in mentality.

Boomstick: It took a lot of magic for Kairi to try and wear down some of her strategic movements, much of which used her inner abilities to keep her distance away from her, and Note's normal and god-based Super Saiyan forms weren't an immediate win because of this. So it wasn't a total washout per se.

Wiz: Except that hardly even mattered because ki and magic are two different entities, with Note being able to conserve her ki better than Kairi with her magic. She's also proven to take on villains on a grander scale, such as with Sealas and the Time Breakers, a group of villains from the Demon Realm that could distribute dark powers across the entire multiverse with such a single spell. And by proxy, she's even gone face-to-face against Fu, who was said to be possibly greater than the Omni King, Zen-Oh, at his peak power. So it's somewhat questionable if Kairi could really keep up with Note's Super Saiyan abilities.

Boomstick: And while Kairi could basically move through stopped time, other Dragon Ball characters have done this nearly perfectly. Goku once moved around in stopped time when Aeos used her Time Freeze, and other Heroes avatars have shared much of these feats and beyond, like the Super Star Break.

Wiz: And even though Kairi can possibly scale to Roxas, who can move through different star systems within a 170 million times the speed of light in seconds, Note has kept up with Xeno Trunks, who can cross the Dragon Ball universe several septillions of times faster than light. This is more than enough to outpace Roxas and be over several quadrillion times faster. Though Dragon Ball has been notorious for not specifying any specific numerical limits, it can still be said that even lowballing Note would still give her a huge advantage other those in the Kingdom Hearts universe.

Boomstick: Though it's hard to say whether or not there are actually limits to these sorts of feats, Note would still have the upper hand when it comes to multiversal strength. Not to mention her cards and hax getting the leg up in sealing any lowered guard that could have been seen.

Wiz: Kairi has managed to go toe-to-toe with guys like Xehanort, who was able to use the power of Kingdom Hearts with 110 yottatons of force. More than impressive, but Mechikabura had his Chaos Ball consume the times of the infinite multiverse and all of time itself, one that weighed in at an estimated 20 tenaFOE of force.

Pop-up Note: While it's arguable that alternative factors such as the Universe Tree could be on the same level as Kingdom Hearts, it's likely that the moon's maximum output would only be more than the minimum amount for the big tree.

Boomstick: And when the Keyblade was suddenly struck down from her, it forced her to get more of a hand-to-hand scenario, which doesn't come very often for Keyblade users. Note comes from a world where an avatar can basically learn any move they want and practically shatter reality and put it back together again just as easily.

ADVANTAGES AND DISADVANTAGES

• Note
  • (+) Stronger, faster, and smarter
  • (+) Better hax to boot
  • (+) Cards were able to help her out as well
  • (+) Key Sword could lock down Kairi
  • (+) Could easily break the Destiny's Embrace without Darkness
  • (-) Not that proficient in magic
• Kairi
  • (+) More agile and evasive maneuvering
  • (+) Further experience with similarly fast opponents
  • (+) Had a better defense...
  • (-) ... But lacked heavily in offense
  • (-) No proper workaround against Ultra Instinct
  • (-) Unable to affect the Hero Switch or the Key Sword whatsoever

Wiz: So really, Note had everything scouted except for Kairi's defense, though that's also up for debate if one might be asking. Both have shown to have taken much harsher hits from villains like Xehanort and Broly, but Note's been able to survive attacks that would have killed her, unlike Kairi, who has been managed to be killed more easily.

Boomstick: The only viable options left were firstly to try and disable the Hero Switch, which removes any access to the avatar state and turns the user back into a human... Well, good luck with that because a Hero Switch user can't exactly be removed of their compatibility. The second was to manipulate Note's power like other princesses would for increases... assuming that she could even catch her.

Pop-Up Note: Note could also use the Hero Switch to go back in time and redo the fight over and over again. Kairi has shown to have some capabilities with time travel, but this required extra firepower to get it done, as seen in Kingdom Hearts 3.

Wiz: Much like a Keyblade user, the Hero Switch is bonded with the compatible SDBH player, and although it does has its drawback of taking so much pain, it's shown to have a faster cooldown period at times after the right amount of training.

Boomstick: And Note has proven this in World Mission, so even if Kairi DID find a way to disable the Hero Switch, she's also had to tango with her cards and the Key Sword.

Pop-Up Note: It's likely that if Kairi were to be given Aqua's abilities and Keyblades, the result could have been much different, but the scaling would be another issue in itself.

Wiz: Taking this into account, the Key Sword was basically all that was needed as the Saiyan Heroine's last resort to lock down Kairi and her abilities. Kingdom Hearts is no stranger to having characters lose their abilities and even their memories to a lesser scale.

Boomstick: And I'll just say it right here: I'd choose the Key Sword over the Destiny's Embrace any day of the week. One disables the darkness, and the other disables basically everything. Kairi was just stuck in a battle where even trying to hide would be useless.

Wiz: Despite Kairi putting on a great effort holding her own in this fight, Note's wider variety of moves, ruthless fighting style, and more absurd hax was what did the trick for dethroning the Princess of Heart.

Boomstick: Even against the power of the light, Note sure brought Kairi's Destiny to a Key-ller ending!

Wiz: The winner is Note!

Trivia

• The connections between Note and Kairi are that they are teenage heroes that travel across the multiverse (Dragon Ball and Disney/Final Fantasy respectively) and fight off against the forces of evil (ex: the Time Breakers and the Heartless). They're part of a higher group of powerful warriors (Note is part of the Dragon Ball Heroes team and Kairi is one of the Princesses of Heart) and is shown to be the protagonist's love interest (Beat is Note's boyfriend and Kairi cares deeply for Sora). Both are capable of wielding powerful weapons (the Key Sword & the Keyblade, which inspired the Key Sword) and have trained under powerful beings (Whis and Yen Sid).
• The soundtrack for this fight would be "Destined Heroines". This is referencing Note's nickname as the Saiyan Heroine and Kairi being the wielder of the Destiny's Embrace Keyblade. The cover of the soundtrack would have a colored silhouette of Kairi's Destiny Embrace with Note's red hair bow on the handle. The song itself would be a rap rock arrangement sung by a female singer.
• This fight would be animated in 2D sprite animation or 3D Source Filmmaker.
