Finn & Jake vs Seryu & Koro

Finn & Jake vs Seryu & Koro is a What-if Death Battle featuring Finn and Jake from Adventure Time and Seryu Ubiquitous with her Imperial Arm Koro from Akame Ga Kill.

Description
Adventure Time vs Akame Ga Kill! Justice is a powerful thing, but only the truly determined can serve it! Which human dog duo will live to see another day?!

Intro
(Cue: Jim Johnston - Invader)

Wiz: In a world filled to the brim with powerful weapons, monsters that bring nothing but death and chaos, and corrupt societies, many will often try and bring justice to the world. Though, everyone has their own interpretation of how to achieve it. Whether it be through helping those in need, protecting the environment-

'''Boomstick: Boring! Everyone knows the best way to serve justice is to fight and slay evil villains and monsters! And what better companion to help kick ass than man's best friend, the dog!'''

'''Boomstick: And Seryu and Koro, the justice seeking duo of the Jaegers! He's Wiz and I'm Boomstick!'''

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

Finn & Jake
(Cue: Adventure Time 3DS - Dungeon theme)

Wiz: A thousand years ago, a great and terrible war waged. The Mushroom War. This war left the world devastated and forever changed. Humanity was ravaged, and nearly brought to extinction.

'''Boomstick: Yeah, and the humans that did survive the obviously nuclear war were forced to leave the main land and live on tiny islands. On this "Hub Island", some con-artist named Martin hooked up with a lady name Minerva and they eventually had a kid.'''

Wiz: This child is Finn Mertens. However, one day while Martin was taking care of the young infant, he was attacked by a group he had previously tricked. And when he fled, Martin left baby Finn on a raft to stop a giant robot, promising to return. However, he never did. The infant was left drifting on the ocean until eventually washing ashore on the land of Ooo.

'''Boomstick: Damn, that's actually really sad. No wonder the kid was afraid of the ocean for a while. Anyway, eventually a pair of crime solving dogs found the baby human and decided to take him in.'''

(Cue: Adventure Time 3DS - I Am So Determined You Have No Idea)

Boomstick: Speaking of, one day Joshua and Margaret were out hunting a pie thief, when they were ambushed by some shapeshifting alien.

Wiz: This alien, Warren Ampersand, bit Joshua and infected him with a venom that would soon develop into... this.



Boomstick:...Jesus, what the hell were these writers smoking when they made this?

Wiz: Joshua and Margaret decided to raise this... "child" and name him Jake. From then on, Finn and Jake were raised to become crime fighters and defenders of peace. And eventually, they would become some of the best heroes in the land of Ooo.

Boomstick: Yeah, considering what these two have been through, I'd say that's pretty accurate.

(Cue: Adventure Time 3DS - Party In the Clouds)

'''Boomstick: These two are ridiculous. They've fought and killed countless monsters, saved princesses more times than Mario, and have been to literal hell and back!'''

Wiz: And like many heroes, Finn and Jake often use weapons in battle. Though, Finn has had and lost many swords throughout his life. Today, we will only focus on his most recent and most reliable equipment.

'''Boomstick: Like the Night Sword. This beauty of a blade was enchanted with dark magic and can cut through ghosts like butter. Plus it's got a built in compass! And after losing his arm, twice (long story), Finn was outfitted with a new mechanical arm, courtesy of Wiz's secret crush.'''

Wiz: Wha- hey! Ugh... *Ahem* Like my own mechanical arm, Finn's bionic arm has a multitude of different features and abilities. From the mundane fan and massage functions, to a rock drill and weed wacker capable of shredding Fern to pieces. And if Finn were to somehow lose his current sword, he'll always turn to his Root Sword just in case.

'''Boomstick: What can this thing do? Summon vines from the ground? Give him control over all plant life?'''

Wiz: It's... just a sword with a handle made from tree roots.

'''Boomstick: What?! That's lame! (Boomstick sighs) Whatever. Moving on, Finn's also got a crossbow. But he's not very good with it, and he's only got one arrow for the damn thing.'''

Wiz: Finn is also exceptionally gifted in unarmed combat too, able to outmatch people and monsters that should normally be far outside his skill set. And if Finn were to ever find himself in a tough situation, Jake will always be there to back him up.

(Cue: Adventure Time: Explore the Dungeon - Boss theme)

'''Boomstick: Yeah, Jake got the same shapeshifting powers as his alien pappy. And boy let me tell you how awesome they are! Jake can stretch his limbs, shapeshift into just about anything you can imagine, and grow to the size of mountains!'''

Wiz: Jake's body is incredibly malleable and near the point of being fluid. He can morph his body parts into fully functioning weapons, take control of a person from the inside and even have Finn wear him as a form of armor. Eventually, Jake's body began to go through an even greater transformation, in which he began to resemble his extraterrestrial father.

(Cue: Adventure Time 3DS - Boss theme)

'''Boomstick: And together these guys have been through just about everything! They've fought giant monsters, beat the shit out of the Ice King on a weekly bases, traveled across land, sea, space, even alternate universes, and stopped the Lich King from destroying all life on several occasions. They've even survived one of the most horrifying things in the world... love!'''

(Cartoonfan's note: Finn and Jake are also capable of reacting to the Ice King's ice lightning magic, which has shown to be comparable to real lightning.)

Wiz: They've endured being frozen solid, falling into a volcano and being poisoned. Even on their own, Finn and Jake are incredibly impressive. Finn has shown many feats of great strength and pain tolerance. Finn is strong enough to not only lift a tree, but swing it around like a club. He's shrugged off having both of his legs broken at the same time, suffering third degree burns, having his arm ripped off, taking punches from giants, and even took a beating from his best friend when the two got into an argument.

'''Boomstick: Speaking of, Jake's a power house! He's much, MUCH stronger than Finn! He can tear through trees like nothing, smash apart solid stone and can bitchslap giant monsters away with ease! Plus he's tough enough to have an anchor fall on him, falling through several stories of metal floor, being struck by lightning twice in one day, and even having a bunch of arrows struck into his body at once!'''

Wiz: But don't overestimate Finn and Jake's capabilities. Finn, while he's certainly impressive for a human, is still human, and can likely be killed through most traditional means. And while Jake is most certainly more powerful than most his partner, he's very lazy and much less aggressive then Finn, often following Finn's lead in combat.

'''Boomstick: Plus, these guys aren't that bright. Not that they're complete dumbasses, but they don't really rely on strategy. Which, while I can respect them for, doesn't always lead to good decisions. But despite all that, there's a reason why Finn and Jake are considered the heroes of Ooo.'''

Finn: "Do you think I've got the goods, Bubblegum?! Cause I am into this stuff!"

Princess Bubblegum : "Yeah I know! And yes I do!"

''Finn: "Then off I go!" *Finn jumps out of a tower window* "Jaaaake!!!"''

''Jake: "Huh?" (Jake stretches himself to catch Finn)''

Finn: "Thanks pal! Bye princess! You know what time it is, buddy?"

Jake: "Aaadventure time?"

Finn: "Yeah, man!"

*Finn and Jake fist bump and ride off to retrieve the Enchiridion as the Adventure Time logo appears*

Seryu & Koro
(Cue: Akame Ga Kill - Fallen Heroes)

Wiz:  A long time ago, a powerful nation was formed, ruling over most of the known land. This empire was... the Empire.

'''Boomstick: Really? Real creative, guys. Now, this place may seem like a nice place to settle down, maybe start a family, own a business or whatever, it's actually... well an absolute shithole filled with psychotic rich people who'll torture and murder you with no remorse and a corrupt government that let them get away with it!'''

Wiz: The Empire had thrived, unopposed for roughly a thousand years. Until one day a group of revolutionary rebels was formed, set on dethroning the current Emperor and ending their tyranny for good. To fight back this new threat, the Empire needed more than just the regular Imperial Police force. And thus, the Jaegers were formed. The Jaegers are an elite class of warriors trained in various methods of combat.

'''Boomstick: From the mad genius of Dr.Stylish, the zombie commanding Kurome, to the pyrotechnics expert Bols, these guys are pretty fitting for the job. But none of them were nearly as into fighting people and serving justice than Seryu Ubiquitous.'''

(Seryu sees a lost Tatsumi stumbling about.)

Seryu: "Oh my. My justice sensor is acting up! You there! Can I help you with something? I am Seryu of the Capital guard forces. A warrior of justice!"

(Cue: Akame Ga Kill - Esdeath)

'''Boomstick: Aww, how can this chick be a member of an elite task force? She looks so harmless and sweet. She's even got her own puppy, that's adorable!'''

Wiz: Before she would become a member of the Jaegers, Seryu was the daughter of an unnamed Imperial police officer, who was murdered by Night Raid, one of the Revolutionary Army's factions. Swearing vengeance upon the rebel group, Seryu soon began her training to become an Imperial officer herself.

'''Boomstick: Hell yeah, that's my kinda women! She kicks ass to avenge her parents! But before the time came, Seryu volunteered herself to undergo some experimentations by Dr.Stylish to make sure she could kick even more ass. And by that, I mean she had fucking guns implanted under her arms and in her mouth! Oooh, this girl just keeps getting better and better!'''

Wiz: That was also when she met her soon to be Imperial Arms, Hekatonkheires.

Boomstick: Imperi-what now?

Wiz: Imperial Arms, or Teigu in Japan. See, when the Empire was originally founded, the original Emperor feared that his nation would fall. So he hired the greatest scientists from around the world to create 48 Imperial Arms, weapons that vary in both power and types. Hekatonkheires in particular is a biological Imperial Arms, meaning it is a sentient weapon, and is very loyal to its owner.

(Cue: Akame Ga Kill - Rasetsu Yonki)

'''Boomstick: But Hekatons of fun is hard to say, so Seryu just calls him Koro. And boy is this puppy awesome! He may not look like much now, but when he's in combat, you'd better watch out! Cause he becomes a monster! He can grow to be much bigger than a person, and even grow giant man arms to punch the shit out of his enemies!'''

Wiz: What's more is that Koro has three rows of razor sharp teeth, which it uses to tear through people with general ease. And like other biological Imperial Arms, Koro processes a healing factor which is tied to a core inside its head, allowing it to regenerate if it takes damage. Lastly, like all Teigu, Koro has a final trump card which can be activated on command by the user. Koro's in particular is Berserker.

'''Boomstick: When he goes berserk, Koro becomes even more of a beast! He becomes much stronger and faster than before! Plus he can roar so loud, it can stun anyone nearby. At least, anyone but Seryu herself. With her new found weapons and partner, Seryu would set off to fight Night Raid and avenge her father once and for-'''



*Seryu screams in pain*

'''Boomstick: Ohh.... well shit.'''

Wiz: Despite losing her arms in battle, Seryu was still eager to fight and kill the members of Night Raid. And she even succeeded in that regard. From that point on, Seryu became a member of the Jaegers and received quite a few upgrades from Dr.Stylish.

(Cue: Akame Ga Kill - Gekisen) (Skip to 1:32)

'''Boomstick: Now we're talking! Seryu and Koro had their bodies modified by the mad doctor and were outfitted with an arsenal fittingly dubbed the Judgement of the Ten Heavenly Kings!'''

Wiz: While these new weapons aren't Imperial Arms, they're still powerful and incredibly useful in battle. Number 1 is Shinkou's Ball of Justice, an extremely large flail which Seryu can swing around to clear out a large group of enemies. Number 2 is a set of four turrets that can fire off dozens of missiles at once. Number 3 is the Sung Dynasty Blade, a large sword used to cut through a target with ease.

'''Boomstick: Number 4's a hook shot that she can use like Link to close a distance quickly. Number 5, Enma's Spear of Justice, is my personal favorite. It's a giant ass drill that mows down enemies like nothing! And if that's not enough, Seryu can launch that sucker at people like a goddamned rocket! Speaking of, Number 6 is a huge reinforced missile that's even bigger than Koro in his Berserker mode!'''

Wiz: Number 7 is Taizan's Cannon of Justice, an anti-tank rifle. Number 8 appears to be a missile launcher attached to Seryu's left arm. Number 9 is Seryu's City Justice Detector, a radar that, while it doesn't have any combat functions, can be used to detect life forms from long distances, making it the perfect counter against potential ambushes.

'''Boomstick: And if Seryu needs a little extra firepower, she'll combine Numbers 2, 7, and 8 in a special technique called Justice Volley Fire! Now, while all of that is awesome, I have one question: How the hell does Koro fit all of that in his tiny body?!'''

Wiz: Likely through some sort of magic that was used when the Imperial Arms were made in the first place.

(Cue: Akame Ga Kill - Yami O Kiru)

Wiz: Lastly, if Seryu were to find herself in an unwinnable situation, she will activate the final Number; Chakravartin Furnace of Five Hells. This is an ultimate last resort bomb literally implanted inside of her head with enough power to destroy everything in the surrounding area.

'''Boomstick: Including Seryu and Koro themselves. *Cough* Well regardless, Seryu and Koro are a kick ass duo! Seryu's strong enough to beat the shit out of Mine with her bare hands and even punch her several feet into the air, and Koro's so strong, he can rip people in half like nothing and nearly crushed the same pink haired girl in his hand.'''

Wiz: Mine was shown to be capable of dodging lightning, and since Seryu and Koro can keep up, and even overwhelm her at points, both should be able to do the same. Plus Koro's healing factor has allowed it to survive having holes blasted in its body, having part of its head cut off, and even being nearly incinerated by Mine's Imperial Arms, Pumpkin.

'''Boomstick: Plus Seryu's got some crazy pain tolerance. When she had both of her off chopped off, she was too focused on winning the fight to give a shit! Hell, the two were even cut in half, and neither of them died! ...Until Seryu's suicide bomb went off.'''

Wiz: But don't mistake pain tolerance with durability. Seryu and Koro were still cut in half. Plus Seryu and Koro are incredibly reliant on one another in battle. Without Koro, Seryu would lose access to all of her weapons save for her arm and mouth guns. And without Seryu to give orders and commands, Koro would be become a wild and unfocused animal.But Seryu's most glaring weakness is her blatant insanity and hubris.

Boomstick: Wait what?

*Koro in Berserker form grabs Mine*



Seryu: "CRUSH HER TO DEATH!!!"

Boomstick: Ohhh...

Wiz: Seryu is incredibly bloodlusted and believes that the world is black and white, that she is the hero who can do no wrong and that anyone against her or the empire is completely evil, when in reality she's no better than the people she claims to fight. Should someone attempt to question her twisted viewpoint, Seryu will become much more violent and psychotic.

'''Boomstick: Meh, I've seen worse. But don't forget that Koro's got a limit to how much damage he can take, and eventually he won't be able to heal anymore. But regardless, you had better stay out of their way, or else you'll feel the true power of justice!'''

*Seryu is seen laying next to Koro, who is eating Sheele's corpse.*

Seryu: *Giggles psychotically* "I did it! Even though she abandoned her evil comrade, I fought well... What a half hearted person."

*Seryu raises her amputated arms into the air and looks into the sky*

Seryu: "Papa, I defeated the evil villain on my own! The light of justice shines upon the world!"

*Seryu's giggles soon devolves into an echoing psychotic cackle as everything fades to black*

Intermission
Wiz: Alright, the combatants are set! Let's end this debate once and for all!

'''Boomstick: Hey Wiz. You know what time it is?'''

Wiz: Huh?...It's time for a Death Battle?

'''Boomstick: What? No I was gonna say 'IT'S ADVENTURE TIME!' ...But that works too I guess.'''

Battle
(Cue: Akame Ga Kill - Jaegers)

The setting is the Candy Kingdom, a place filled to the brim with color, life, and of course, sweets. The sun sets and the stars begin to shine as the sky turns into an incredibly dark blue. On top of the large candy wall, two figures could be seen.

One was a small, white, bipedal dog with a collar around its neck. The other was a young adult woman with orange hair who wore a green uniform. She also had two mechanical arms instead of regular human arms. It was Seryu Ubiquitous and her Imperial Arms, Koro.

Seryu held a pair of binoculars over her eyes with one hand, observing the top floor of the candy castle, as if looking for a target. Until she saw said target: Princess Bubblegum. A psychotic smile rises on the cyborg girl’s face.

''Seryu: “Perfect! All is going according to plan. This special mission the General assigned me will be over in an instant. And once that evil tyrant is delivered the justice she deserves, this kingdom will be freed and the capital will bring this civilization to a new found order!”''

The justice hungry Jaeger lowers her binoculars and holds out her free right arm.

''Seryu: “Koro! Number 7!”''

Then, the small dog’s mouth suddenly grows to extreme proportions before biting down on it’s owner’s arm. However, instead of tearing it off, the Imperial Arms opens its maw, replacing Seryu’s arm with a long anti tank rifle. Seryu’s smile only grows as she aims her weapon arm at the tower.

Seryu: “Say goodbye, evil-doer!”

Before her rifle could even fire, a loud battle cry is heard. The girl’s eyes widen with shock and she looks downward just enough to see the source: which was a teenager wearing a white bear hat, a blue shirt and pants, a green backpack and a mechanical limb in the place of his right arm riding a yellow orange dog.

(Cue: Adventure Time 3DS - Ice King)

Before the Jaeger could even proces this, the young adventurer jumps off of his canine partner and punches Seryu in the face hard enough to knock her off balance.

She stumbles backward until she trips and falls off backward off the wall. Koro yelps and jumps after her. While in the air, the small dog’s entire body grows to become many times larger than before. It grabs its master and spins around, using its own body as a cushion for Seryu. The two slam into the ground hard enough to create a small crater underneath them.

The duo quickly get back onto their feet before looking up to see their assaulters, who land a few meters away from them. Jake stretches his legs enough to where he can land on the ground safely while Finn rides on his back. When the adventurers land, Finn hops off of Jake’s back and they turn to the Jaeger and Imperial Arms.

''Finn: “What the heck is wrong with you, lady?! You just tried to kill a princess!”''

Seryu grits her teeth and points at the young human.

''Seryu: “Her position of power doesn’t matter! She is an evil tyrant that must be punished for her crimes! And if you wish to stand in my way, then I’ll have to bring you both to justice too! Koro! Arms!”''

(Cue: Shantae and the Pirate’s Curse - Darkest Night (Remix))

The Imperial Arms’ nub arms then stretch and morph, becoming much similar to that of muscular human arms. Finn and Jake’s eyes widen at the sight. The young human quickly draws the Night Sword from his backpack and takes a fighting stance. The magic dog jumps into Finn’s backpack and pokes his head out from it.

Jake: “Man, that lady’s nuts!”

Finn: “No kidding… Well we’ll just have to take these creeps down!”

''Seryu: “Tch. Such corrupt evil at such a young age… Koro! Crush them!”''



FIGHT!!!

Koro rushes at the adventurers, punching at such a pace that its arms could only be seen as blurs. The young human barely has enough time to hold out his blade to block the monstrous dog’s attacks. Finn strains to keep up with the ferocious beast. Jake’s left hand stretches and grows before slugging Koro in the face hard enough to make the Imperial Arms stumble backward.

But as it does this, Seryu leaps into the air and aims her anti tank rifle at the defenders of Ooo, her psychotic smile returning. She fires a round at the heroic duo, barely giving them enough time to jump out of the way. The resulting explosion sent all four combatants flying in opposite directions. Koro’s feet skid across the ground before stopping. The Imperial Arms catches its master and sets her on her feet.

''Seryu: “Koro! Number 1!”''

Koro’s jaw opens and once again bites down on Seryu’s right arm. When it opens, the rifle is replaced with a large green flail that was about the size of Seryu’s body. Meanwhile Finn lands on his feet before seeing Seryu switching her weapons. Acting quickly, Finn charged at the Jaeger, aiming to slash her with his sword.

The red headed Jaeger swings the flail with little effort at the heroes. Finn ducks under the giant iron ball before he jumps into the air. He brings his sword down, aiming for Seryu. But before he could get close, Koro lunges at the young human and punches him square in the stomach, sending the two flying into the Candy Kingdom’s wall.

When the defenders of Ooo fall to the ground, Finn holds his head. He looks up to see the Jaeger and Imperial Arms charging at them, with Seryu swinging her flail downward at the heroes, aiming to crush them. Jake quickly forms into a large dome around his partner, blocking Seryu and Koro’s assault.

A segment of the Jake dome opens and the young human leaps out and slashes at Seryu, who could barely react in time to block the attack with her left arm. She jumps backward and swings her flail once at Finn, who slides underneath it. Koro turns to aid its master when it feels a sharp pain in its back. Jake had morphed his hand into an axe and planted it into the Imperial Arms’ back. The magic dog retracks his hand.

''Jake: “Hey ugly! Come and get me!”''

Jake turns and smacks his backside in a taunting fashion, causing Koro to growl and stomp over to the shapeshifting dog. Koro throws a series of fast punches, which Jake barely dodges. One punch finally lands and hits the magic dog in the face, which leads to more punches connecting with Jake’s body.

''Jake: “Ow ow ow! Okay, okay! You called my bluff!”''

The magic dog stretches his body and wraps it around one of Koro’s arm before enlarging his hand, which he uses to punch the Imperial Arms in the mouth three times. Before Jake could get a fourth hit in, Koro grabs him by the waist and rips the dog off of its arm. It then lifts Jake into the air before slamming him into the ground hard enough to make a divot.

Back with the humans, Finn and Seryu are seen attempting to attack one another, but when the young adventurer gets in close, the Jaeger blocks his attacks and maneuvers her way around him, avoiding his attacks. Then the two heard a loud slam coming from a ways away. Finn looks away in the direction of the dogs.

''Finn: “Jake! I’m coming buddy!”''

But before the human could even make a move, Seryu finally hits Finn with her flail. The force from the attack sends him flying into a nearby patch of woods.

''Seryu: “Good job Koro! Now help me end this corrupt defender of evil!”''

Seryu’s Imperial Arms returns to her side and the two head off in the direction Finn was sent in. Meanwhile, Jake sits up and holds his head, groaning in pain. The scene cuts back to Finn, who had landed in a tree, laying atop of a large branch. He sits up and looks around, taking in his new surroundings.

Before he could do anything else, Koro smashes through several trees, knocking them over. Seryu follows close behind, her flail replaced with her regular mechanical arm. Though it had a large radar strapped to it. The young adventurer reaches for his sword, only to realize that it was nowhere in sight.

''Finn: “Wha? You’ve gotta be flipping kidding! Ugh, fine, let’s see…”''

The young adventurer digs into his backpack before finding his crossbow. He smiles and pumps his fist into the air. He quickly rummages through his pack again before finding his one arrow for the weapon. He loads it and aims it at Seryu.

''Finn: “One shot, Finn. Make it count.”''

Seryu’s city justice detector began to blink. She looks at it and sees an orange dot, which she quickly gathered to be Finn. She smirks and turns in the direction of her target.

Seryu: “Koro!”

Koro growls before turning toward the tree that Finn was in. The young hero fires the arrow, which flies through the air, swishing past the imperial Arms. The Jaeger’s eyes widen and she quickly side steps to her right, avoiding the oncoming projectile. The arrow jams into the root of a tree.

''Seryu: “Of course. I should have expected a lowly villain like you to try a sneak attack! But justice is always prepared! Koro, prey!”''

(Cue: Castlevania: The Arcade - Black Knight)

The Imperial Arms growls before it punches the tree that Finn was in. It shakes before it soon falls over. Finn jumps off the falling tree and rolls on the ground before he stops and stands up again. The Jaeger charges at the human and goes for a punch. Finn blocks the attack before throwing a punch himself, hitting Seryu in her right cheek and making her stagger backward.

Finn tries to punch Seryu again, but she quickly blocks the attack and headbutts the young adventurer. She smirks and unleashes a flurry of punches onto him.



She continued this for several seconds before uppercutting Finn into the air.

Seryu: "Koro! Devour him!"

Koro roars and opens its maw, exposing its many rows of fangs, ready to eat the defender of Ooo. Then, two giant, yellow hands stretch from beyond the treetops and grab the Imperial Arms' jaws. Jake stretches himself onto the scene and catches Finn in the air.

Jake: "Finn! You okay, pal?"

''Finn: "(Groans) Yeah, I'm fine."

K.O.!!!
