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.

Knuckles the Echidna[]

Wiz: 4000 years ago, the Knuckles Clan wanted the power of the Master Emerald for themselves.

Boomstick: But the Knuckles Clan wanted the power of the Master Emerald so badly, they didn’t realised it was protected by a water monster named Chaos. Where it killed all the echidna clan. Wiz: Fortunately, a young echidna girl survived and managed to seal Chaos into the Master Emerald. The remaining energy ripped the echidnas home and formed Angel Island.

Boomstick: Centuries later there is only one last echidna standing in the, his name is Knuckles the Echidna.

Wiz: Knuckles the Echidna was born on Angel Island and had lived his life alone protecting the Master Emerald. Sadly, Knuckles had no knowledge or memory about his clan and has always believed to be the last one of his kind.

Boomstick: But he only knew that he lives on Angel Island alone to guard the Master Emerald from being stolen.

Wiz: With the Master Emerald removed, Angel Island will no longer float and plummet to the ground. Even if Knuckles did guard the Master Emerald, those who try to steal it, do. Especially from Dr. Eggman.

Boomstick: Knuckles got tricked by Eggman thinking Sonic would steal the Master Emerald. But it turns out, the evil genius tricked him and stole the Master Emerald for himself.

Wiz: As Sonic knocks some sense into Knuckles, they work together to take the Master Emerald back. Afterwards, the two form a friendly rivalry.

Boomstick: With the Master Emerald being stolen very often, Knuckles is a skilled treasure hunter and has the ability to sense where the Master Emerald's location is.

Wiz: A loner by nature, Knuckles is independent, headstrong and serious. His signature ability is his immense superhuman strength, so strong that he can smash massive boulders, punch through solid steel, and lift objects several times his size and weight with ease.

Boomstick: Using this strength with his Shovel Claws can make extremely deadly blows. Whenever he sees something, he punches it, see a solid wall, he just punches it again. He can destroy things without even suffering recoil to his arms.

Wiz: Knuckles’ brute strength and mastery of martial arts can have him to perform limited Pyrokinesis and Geokinesis. By punching the ground, he can create fissures, tremors, and even small volcanic eruptions. Such a feat requires over 3.9 megatons of force.

Boomstick: Dang, that’s gotta be tough. There’s still more to his punches.

Wiz: By spliting the air molecules and igniting the hydrogen in the air by friction, Knuckles can launch such powerful punches with great force that they cause air molecules to split and create explosions of enormous power.

Boomstick: Outside of his immense superhuman strength, Knuckles can perform other kinds of abilities such as speed, reflexes and durability to add to his super strength. He can react to Sonic and Shadow’s speed attacks, even reacted to Super Mecha Sonic’s speed as well.

Wiz: He can apparently breath in space and Knuckles can run at speeds comparable to Sonic but not at the latter's fastest. He can outrun machine gun fire, putting his speed around 1,700 mph. He can also run so fast that the ground crumbled beneath him.

Boomstick: Knuckles is also durable enough to survive a bomb exploding through his sheer toughness, able to going through atmospheric re-entry, survived digging into hot furnaces like a volcano and survived from that explosion that destroy part of Sky Sanctuary. In fact, he has enough stamina to hold out against an army of enemies without breaking a sweat.

Wiz: By taking account into all these durability feats, Knuckles can survive temperatures over 3,000 degrees farenheit (1649 degrees celsius) and survive about 5 kilotons of force. By trapping the air under his dreadlocks, Knuckles can glide through the air at very long distances. With the spikes on his fist, Knuckles can climb on walls.

Boomstick: He has many different techniques such as Digging, Punch Attack, Spiral Upper, Drill Claw, Hammer Punch, Thunder Arrow and the Maximum Heat Knuckles Attack. But that’s not the last of his abilities.

Wiz: By powering himself with the 7 Chaos Emeralds, Knuckles can enter a form so powerful, Super Knuckles. This form drastically increases and far surpasses his normal physical abilities. This additionally, gives him the ability to fly at speeds that is nearly as fast as light, regenerate himself and is virtually invulnerable to any form of attacks.

Boomstick: He is so strong and powerful that he can destroy giant battleships and throw punches so powerful to shoot fireballs that explode on impact. But that’s not his strongest form.

Wiz: After the chaos emeralds were powered by the Master Emerald, Knuckles can achieved a form that surpasses Super Knuckles, Hyper Knuckles.

Boomstick: Hyper Knuckles gains all of Super Knuckles’ abilities, giving him total invincibility, can hit surfaces with a shockwave that can destroy his enemies around him and he’s definitely faster than light. Though not as fast as Hyper Sonic, but still very impressive.

Wiz: However, without a steady amount of rings, this form last for only a certain amount of time before reverting back into his normal form. Knuckles does have some drawbacks, though a skilled treasure hunter, he is not the smartest of the team.

Boomstick: He tends to oftenly fall for Eggman's tricks, oftenly jumps into fights without a form of strategy and possesses a huge ego. But still, Knuckles is still living his life alone on Angel Island, trying to protect his home island.

Knuckles: I'll probably be on this floating island forever, guarding the Master Emerald again. I may not know the whole story behind this, but perhaps it's better that way.

Erza Scarlet[]

Wiz: Erza Scarlet, an S-class wizard of Fairy Tail. She happens to be born by a lady named Irene Belserion, the enchantment wizard and creator of Dragon Slayer Magic.

Boomstick: With Irene being pregnant with Erza while possessing Dragon Slayer Magic, she starts to form Dragon Scales and was abused by her own village.

Wiz: She eventually, turns full dragon and withheld her pregnancy for 400 years. With Zeref's help, Irene was able to change back to her human body but can no longer have the traits to being a human again.

Boomstick: With having the idea to enchant herself into Erza's body, she then just well... saw the baby's smile, surrendered her plan and dropped the baby at Rosemary Village.

Wiz: While Erza being remained at the Village, a bunch of Zeref followers take everyone at the village as slaves including Erza. While being treated as a slave, she meets a boy named Jellal. Who calls her name, Erza Scarlet because of her scarlet hair.

Boomstick: However, Jellal became possessed by an evil spirit and became an evil being himself. As Erza attempts to escape the Zeref followers, she had lost her right and had discovered the use of her own magic defeated some guards and was eventually freed. After her freedom, she joined the Fairy Tail guild.

Wiz: Erza's primary magic is Requip Magic, a type of magic to store items into a pocket dimension so that it can be summoned anytime.

Boomstick: The type of items she uses are armor and weapons, each armor carries out different physical and magical abilities such as the Heart Kreuz Armor, Heaven's Wheel Armor, Black Wing Armor, Flame Empress Armor, Armadura Fairy, Nakagami Armor, Ataraxia Armor and... Seduction Armor? I don't even know why she carries that to be honest.

Wiz: She says she uses it for “private uses” but hasn’t shown to use the seduction armor in battle yet. But if I had to guess Boomstick, it probably be to seduce her male opponents. However, she has other types of skills and abilities. Proficient at sword fighting, hand-to-hand combat, immense durability and endurance and an artificial eye to be unaffected by illusion abilities.

Boomstick: Her physical and magical abilities depend on what kind of armor she uses. For example, the Flight armor was able to move at super speeds. Her Piercing Armor gives great strength that it can pierce through several stone walls.

Wiz: Her mostly used armor in her arsenal is the Clear Heart Clothing, not a particular type of armor but it just sheds all her defense for mobility and offense. But some of her greatest feats are having to defeat 100 monsters, survive a 2 kiloton island blast and destroyed a falling meteorite.

Boomstick: Look at the size of that meteorite compared to her.

Wiz: By measuring the size of Erza compared to the metorite, we can determine her sword must have applied about 900 kilotons of force.

Boomstick: And she did it when her bones were broken. That’s gotta take a lot of endurance and willpower to do so.

Wiz: Unfortunately, even Erza has her own weaknesses. Her supply of magic is limited and swapping armor requires her use of magic. If she is not careful, she could run out of magic power and cannot continue fighting. But her main weakness would be overexerting herself into harms way such as the time she continued fighting a bunch of baby dragons despite her injury.

Boomstick: But this badass armor woman is always standing guard for her guild and her friends.

Erza: I will withstand any physical pain, to protect the ones that I love.

Death Battle[]

At Angel Island, Erza is seen walking around the forest holding a job request to search for a giant gem while a figure appears behind the bushes spotting her.

Erza: A giant powerful gem in a floating island? Seems very unusual.

Erza then sees the shrine containing the Master Emerald.

Erza: A shrine? It's the gem, I must take this gem back to my guild.

Erza approaches the master emerald but then sees a figure charging at her and dodges it.

Erza: What? Who are you?

Knuckles: I'm the guardian of the Master Emerald, Knuckles the Echidna. I won't let you take it!

Erza: Stand down, I have to take this gem as part of my job.

Knuckles: Yeah, well talking to you is a waste of time. I will protect the Master Emerald and this island!

Erza: Then we'll have to do this the hard way!

Both take on battle stance


Knuckles starts charging in a starts punching Erza while the latter uses her swords to defend and attack.

Erza backs off.

Erza: He's too tough! REQUIP!!!

Erza changes into Black Wing Armor.

Knuckles: Whoa! What? How'd she do that?


Knuckles dodges the slashes and strikes back with his equipped shovel claws. Clashing with Erza's sword.

Erza: Claws, huh?

Knuckles then pushes Erza back with great force.

Erza changes into Heaven's Wheel Armor.

Knuckles: Again?

Erza prepares her swords.

Knuckles: Lots of swords, huh?


Knuckles charges in and dodges every single sword coming at him. Knuckles uses the Punch Attack combo.

Knuckles: TAKE THIS!!!

As Knuckles punches Erza, breaks her armor and knocks her heavily to the ground.

Erza changes into Flight Armor and charges into Knuckles at high speed.

As Knuckles strikes back he eventually gets hit by Erza's attack, but not as much. Knuckles then punches the ground creating a Volcanic Eruption knocking Erza back.

Knuckles: Try taking this then!

Knuckles carries a boulder and throws it at Erza. Erza changes to Armadura Fairy Armor and slices the boulder and then charges at Knuckles. Knuckles then uses the Maximum Heat Knuckles Attack. Both clash that creates a huge explosion. Knuckles and Erza still stand.

Erza: REQUIP: Ataraxia Armor!!!

Erza summons Blade Wings when Knuckles deflects all of them with his Shovel Claws.

Erza: My blade…

Knuckles: What now?

Erza: Attacks without you noticing.

Knuckles: What? OH NO!

Knuckles feels the slashes.

Knuckles: OWWW!!! That’s cheap woman.

With Knuckles on the ground and Erza barely standing.

Erza: Never underestimate the Fairy Tail Guild, hand over the gem.

Knuckles gets up.

Knuckles: I ain't done yet! I'm just warming up!

Erza: This is your last mistake, echidna!

Knuckles: No, this is YOUR last mistake!

The 7 Super Emeralds float around Knuckles.

Erza: More gems? What's he doing?

Knuckles becomes empowered and transforms into Hyper Knuckles.

Erza: No way, he powered up? All his wounds are healed.

Knuckles: That’s right. Time for a Knuckles sandwich!

Erza: If you insist!

Erza changes into Nakagami Armor.


Erza's attack hits Knuckles but to no avail.

Knuckles: Heh! Like that will work on me!

Knuckles then throws rapid punches, shooting fireballs.

Erza: REQUIP!!!

Erza then changes into Adamantine Armor and blocks the fireballs.

Knuckles: TAKE THIS!!!

Hyper Knuckles’ strikes Erza’s defenses and easily breaks Erza’s armor with a powerful shockwave knocking her back.

Erza: REQUIP!!!

Erza is in her clear heart clothing and then proceeds to attack Knuckles, but Knuckles suddenly appears in front of Erza.

Erza: What!?

Knuckles brutally punches Erza breaking her bones.

Erza: OWWW!!!

Erza slowly gets up.

Erza: No, I can still do this!


Erza uses her hand to jump back up preparing her attack from below while Knuckles continues charging from above performing the Drill Claw. The two clash but Erza is easily overwhelmed and is smashed on the ground into mush. Super Knuckles lands on the ground safely and then reverts back.

Knuckles: Stone Fists!


Knuckles sees Rouge taking the Master Emerald, he chases after her and attempts to fight her. Team Natsu arrives at Angel Island angered about Erza's death.


Boomstick: Holy Crap, that is one hell of a murderous rage.

Wiz: Yep, this battle was something we had to look into carefully. Knuckles had the advantage in speed, strength and power and Erza had the advantage in a wider arsenal and defenses.

Boomstick: Still, with Knuckles’ overwhelming strength and can strike with a 3.9 megaton punch. It’s more than enough to strike Erza’s in one go.

Wiz: But even then, it is still quite unpredictable for Knuckles to know what armor Erza uses. As there are some magical techniques that Knuckles may not know about.

Boomstick: But with Erza’s fighting skill, she doesn’t usually rely on her speed very often and usually attacks until if she can bring down her opponent.

Wiz: But with Erza surviving a blast that is 2 kilotons, Knuckles can deal 3.9 megatons of force. But Erza’s 900 kiloton strike could deal serious damage to Knuckles who survived about 5 kilotons.

Boomstick: So who can deal the killing blow first?

Wiz: Either way, even if Knuckles did or did not get strike, he can always go into his invincible forms, making Erza’s previous strikes futile.

Boomstick: Damn, not even all of Erza’s armors can take the power to destroy a huge battleship or create so many fissures on the ground.

Wiz: It’s very likely that thanks to all the power Knuckles has that outclasses Erza, it is likely that Knuckles can kill Erza before reverting back to normal. But not only that, neither of Erza’s known offensive magical spells could deal damage to Hyper Knuckles.

Boomstick: Erza just couldn’t take the Knuckles Sandwich.

Wiz: The winner is Knuckles the Echidna.

Winner is Knuckles the Echidna

Just Remastered this as well.
