Jin Saotome vs. Gambit
- Battle Strip: He uses it as an attack!
- Eye Pop: After being thrown into the wall, he does this as Gambit comes toward him.
- Humongous Mecha: His mecha Blodia. Or rather, his arm. Which he uses to Punch Gambit into orbit.
- Katanas Are Just Better: He shows it off as a threat to Gambit, but he doesn't use it in the fight.
- Palette Swap: He's wearing a black and yellow outfit instead of his usual white one.
- Playing with Fire: Many of his attacks are powered up with fire.
- Super Speed: After falling into a well, uses this.
- Tornado Move: Spins around in a fire tornado as an attack.
- Death Dealer: Throws cards for special attacks.
Terry Bogard vs. Burai Yamamoto
- Playing with Fire: His special moves use flames.
- Good Old Fisticuffs: His preferred fighting style.
- The Unexpected: He's from a fairly obscure fighting game series.
Akuma / Oni vs. Kenpachi Zaraki
- An Arm and a Leg: In Round 3, Zaraki's bankai slices off his right arm at the shoulder.
- Barehanded Blade Block: Does this to Kenpachi's sword, disarming him in the process. He somehow has it again in time for Round 2.
- Blood Knight: Picks a fight with Kenpachi over being told to move out of his way.
- Cyborg: He cameos at the end of M. Bison vs God Rugal as Cyber-Akuma.
- Gets an arm cut off and his chest slashed open by Kenpachi's sword, but continues fighting nonetheless.
- He also wins Round 3 while missing a limb and bleeding out from a major injury, though he collapses soon after.
- Finishing Move: Demon Armageddon, which he uses to send Kenpachi flying over the horizon after launching him into the air, Misogi to knock Kenpachi out again as Oni, and his trademark Shun Goku Satsu to finish Kenpachi off for good.
- Ground Punch: The Kongou Kokuretsuzan.
- Mutual Kill: In Round 3, Oni hits Kenpachi with his Shun Goku Satsu before kicking him into a tree, but collapses into unconsciousness immediately afterwards due to his injuries. He even falls off the podium during the victory screen.
- One-Winged Angel: Transforms into Oni in response to Kenpachi powering up for Round 2.
- The Berserker: His bankai turns him into an insane oni only capable of unrelentingly attacking his opponent.
- BFS: His Zanpakuto, Nozarashi, is a nodachi as long as he is tall. Its shikai form is a massive cleaver with insane cutting power.
- Blood Knight: Is clearly enjoying his bouts with Akuma.
- Catch and Return: Casually tosses a Hadoken back at Oni.
- Defiant to the End: Even when he's about to get hit by the Shun Goku Satsu, Kenpachi still puts in the effort to throw one last punch.
- Flash Step: Unlike most Soul Reapers, Zaraki doesn't know how to use shunpo. He's fast enough that he doesn't have to.
- I Am Not Left-Handed: Ken gets serious for Round 2. It's still not enough to beat Oni.
- Protected by a Child: Yachiru picks him up after the end of Round 2.
- Super Mode: He uses his bankai (incorrectly depicted with his Zanpakuto's shikai form) in Round 3, turning him into a crimson-skinned oni with insane strength.
- A Twinkle in the Sky: How he gets launched out of the battlefield, courtesy of Akuma.
- Throw the Dog a Bone: Kenpachi lost all three rounds to Akuma and died in the final round, but his opponent won't be getting up anytime soon thanks to Ken severing his arm and slicing him at the shoulder.
- Badass Adorable: She looks like a young girl, but she is the Squad 11 Lieutenant and Zaraki's Zanpakuto Spirit.
- Heroic Fire Rescue: She rescues Kenpachi from a lava flow.
Captain Falcon vs. Captain Commando
- Badass Driver: Naturally for a character coming from a racing game series.
- Bring It: "Show me your moves!"
- Cool Car: The Blue Falcon, which Captain Falcon uses to take out Mack, Ginzu and Baby Head, along with helping to land the finishing blow on Captain Commando.
- Elemental Punch: Falcon Punch, Raptor Boost and Falcon Dive. Technically, the Falcon Kick as well.
- Playing with Fire: As a result of his pyrokinetic attacks.
- Super Speed: At the very end, he outruns the Blue Falcon to land one last Falcon Punch which defeats his opponent.
- Would Hurt a Child: Falcon throws a chunk of rock at Baby Head's... er, head, after being launched back into a boulder by him and the rest of the team's Captain Sword.
Captain Commando (With Mack the Knife, Ginzu the Ninja, and Baby Head)
- Assist Character: Mack, Ginzu, and Baby Head help out Commando in the fight.
- Child Prodigy: Baby Head's only a baby, and yet he designed his own robot.
- Ninja: Ginzu is one.
- Playing with Fire: Captain Fire.
- Spin Attack: Mack spins in the air with his knives to attack.
Batman vs. Albert Wesker
- Badass Cape: Batman wears a black scalloped cape as part of his costume, which he can use to glide.
- Deadly Disc: Uses motorised sawblade-like Batarangs later on that can be thrown or wielded as melee weapons.
- Gory Discretion Shot: Wesker kills him after the screen turns black, hinted by blood splattering on the screen. By extension, this makes him the first One Minute Melee combatant to undeniably die after losing.
- One-Man Army: Takes out all of Wesker's armed goons by himself.
- Pre-Asskicking One-Liner: "The gloves are off!"
- Time Bomb: Uses an Explosive Batarang to take out the last of Wesker's armed henchmen. He tries them again against Wesker, but Wesker proves to be too fast to hit with them.
- Bond One-Liner: "I told you: I was the only worthy one."
- Bring It: "I'll play with you."
- Bullet Time: Dodges Batman's Batarangs this way in the climactic brawl.
- Cool Shades: They get knocked off about half-way through, but he puts on another pair shortly afterwards.
- Finishing Move: Defeats Batman with the Phantom Dance—starting with a combination of fast teleporting kicks, before launching him upward, teleporting above him and stomping him through a stone floor.
- I Shall Taunt You: In contrast to Batman's stoic, no-nonsense attitude.
- Neck Lift: Does this to Batman after incapacitating him, before killing him off-screen.
- Pre-Asskicking One-Liner: "You mortals are so weak!"
Kim Kaphwan vs. Juri Han
- Extremity Extremist: Uses mostly kicks.
- Megaton Punch: Punts Juri so hard, she collapses an enormous temple.
- Would Hit a Girl: In his defense, she was a psycho.
- Blood Knight: Picks on Kim because he looked like she'd give him a good fight.
- Kick Chick: Also uses mostly kicks.
Meta Knight vs. Zero
- Adaptational Wimp: Limited only to his most basic abilities despite being capable of much stronger attacks and techniques, Screams Like a Little Girl upon nearly being hit by the Rekkoha despite normally being very calm and collected, and puts up little resistance as Zero effortlessly knocks him around and eventually kills him.
- Blade Lock: Engages in this with Zero.
- Blade Spam: Of the "Simultaneous Blade Spam" variety.
- Bring It: "Fight me!"
- Cape Wings: He can transform his cape into wings for flight, but does not use them to any major extent- only using them to jump multiple times in mid-air, and then once to steady himself after falling.
- Character Death: He is the first One Minute Melee combatant to die on-screen, and the second overall to perish after Batman in Batman vs. Albert Wesker.
- Cool Sword: His iconic Galaxia Sword.
- Cruel and Unusual Death: He's stabbed through the face with what is essentially a lightsaber, before being slashed upwards and cut in half down the middle- made even worse by the amount of blood splattering on the ground from each of the two halves.
- Death of a Thousand Cuts: He's so quick, his fighting style is basically this.
- Forgot About His Powers: Whilst he does briefly use his wings and cape to jump multiple times in mid-air and teleport to avoid attacks respectively, he does not use his other abilities, such as the Sword Beam and Mach Tornado, despite official sprites for these techniques definitely existing.
- Half the Man He Used to Be: Zero stabs him through the visor of his mask and bisects him vertically.
- Nerf: Barely allowed to use any of his standard abilities beyond his basic swordplay- not even his Super Smash Bros. moves come into play despite using the same voice and appearance as from there.
- Not So Stoic: Freaks out when Zero tries to attack him with his Rekkoha attack, complete with derpy facial expression.
- Out of Character: The above happens despite him normally being very calm and collected, and never reacting to anything in such a way in his own series.
- Teleport Cloak: Uses his Dimensional Cape to warp and dodge attacks.
- Adaptational Villainy: The real Zero would never kill a fellow hero without good reason, nor would he be so outright gleeful at doing so in such a brutal manner.
- Arm Cannon: His Z-Buster.
- Blade Lock: Engages in this with Meta Knight.
- Bond One-Liner: "Just like a training program."
- Cerebus Retcon: Zero later makes a cameo appearance in Mbison vs. God Rugal in Season 4, where he's seen floating in a statis tube in the laboratories of Shadaloo. This adds a lot of credence to the theory that this is either not the real Zero, or that he has otherwise been corrupted.
- Dissonant Serenity: The aforementioned Bond One-Liner above, complete with an unsettlingly cheery "^_^" expression- despite being a robot that has just brutally murdered a living being. Given he called Meta Knight a 'soulless copy', he may not have even realized he had killed anything other than another Maverick.
- Do Not Run with a Gun: Stands still to fire his Z-Buster at Meta Knight.
- Half the Man He Used to Be: Does this to Meta Knight after catching him off-guard with the Rekkoha.
- Laser Blade: His iconic Z-Saber.
- Out of Character: One of the most blatant examples in the series. Although he did win the fight granted, the canon Zero would not have been so outright gleeful about brutally murdering someone, especially not a living being and fellow hero. In many ways, he comes off as outright evil, or at the very least delusional— given that he may not have even realised he's just killed a living being.
- Ridiculously Human Robot: Or Reploid, to be precise.
- Robotic Psychopath: His sociopathic behaviour throughout the fight is eerily similar to his original Maverick self as seen in Mega Man X4 and Mega Man X5, to the point where he gleefully murders Meta Knight.
- Shock and Awe: Rekkoha.
- Sword and Gun: Wields both the Z-Buster and Z-Saber here, along with the Rekkoha.
Bowser vs. Dr. Eggman
- Acrofatic: Proves to be surprisingly fast and agile despite his size.
- Badass Boast: Has one before the fight, punctuated by him crushing a Koopa Shell in his hand."If anyone's gonna pummel that plumber, it's gonna be me. And if you think you're going to turn my future kingdom into a Carnival, you'd better screw that loose bolt in your head back into place! Because this is my turf, bub."
- Breath Weapon: Uses his trademark Fire Breath as an attack at various points, notably using it on the Drill he had broken off from Eggman's Mech to heat it up and launch it back at him.
- The Cameo: Princess Peach can be seen tied up in his throne room in the Prologue.
- Much like Eggman reappearing in Knuckles vs. Wario, he reappears at the end of Bowser Jr. vs. Metal Sonic to rescue Bowser Jr. after he'd received a vicious beating from Mecha Sonic, moving him safely away from the fight before turning on the monstrous mecha himself for attacking his son.
- Catch and Return: Pulls this off twice. First he breaks off the Drill Arm from Eggman's mecha and launches it back at him with his Fire Breath, and later on, he latches onto Eggman's missiles in midair, rides them into Eggman's Mecha and jumps off just before they hit, blowing up the Mech and leading to his victory.
- Dark Horse Victory: Whilst it's not in a DEATH BATTLE!, Bowser's victory over Eggman is the first time a Mario character has beaten a Sonic character in a ScrewAttack video.
- Evil Versus Evil: Against Dr. Eggman, another villain.
- Finishing Move: Launches both Eggman and his Mech off the screen with a Super Smash Bros.-style drop-kick.
- Ground Pound: The Bowser Bomb.
- Large and in Charge: Zig-zagged. Undisputed King of the Koopas, and whilst he's larger than Eggman on his own, he's about half the height of the Battle Egg Mech V1 that Eggman uses to fight him. This doesn't stop him from defeating it, however.
- The Only One Allowed to Defeat You: Claims that only he can destroy Mario, and no else can.
- Spin to Deflect Stuff: Uses the Whirling Fortress to deflect several homing missiles fired by Eggman early on.
- Pre-Asskicking One-Liner: When redirecting the missiles back to Eggman."SHOW TIME!"
- Villain Team-Up: Had one with Eggman before the events of the battle before being betrayed by him, which sets off the fight.
- Acrofatic: Not quite to Bowser's level, but he is a surprisingly fast runner despite being overweight- as shown when escaping from Bowser.
- A Handful for an Eye: After being pulled out of his Mecha by Bowser, he throws dirt in Bowser's eyes; allowing him enough time to run away and quickly get back into it.
- Badass Boast: Also has one before the fight."We'll see who's the "bub" when I make Turtle Soup out of you!"
- The Cameo: He later reappears in Knuckles vs Wario, flying by in his Eggmobile to steal the Master Emerald from Knuckles after he's done fending Wario off from it.
- Combat Pragmatist: Throws dirt into Bowser's eyes to escape from him after being forcibly removed from his Mecha at one point.
- Chronic Backstabbing Disorder: Was working with Bowser before the events of the battle, but betrayed him after completing his new mech, intending to defeat him, along with both Mario and Sonic, to take over his kingdom.
- Evil Laugh: Gets to do his trademark "OH HO HO HO" laugh upon explaining his plans to defeat Bowser, Mario and Sonic and turn Bowser's Kingdom into Eggmanland in the Prologue.
- Evil Versus Evil: Against Bowser, another villain
- Hoist by His Own Petard: Bowser uses his own missiles to blow the arms off his Mecha, incapacitating it.
- Improbable Weapon User: Uses an Egg Walker-style Spring hidden in his Mech's chassis to knock Bowser back at one point.
- Mini-Mecha: The Battle-Egg Mech V1, which he uses to fight Bowser.
- Pre-Asskicking One-Liner: When firing missiles at Bowser—even if it does ultimately backfire on him, but kudos to him for at least trying."Bombs away!"
- Shock and Awe: The electrified drill is capable of firing bolts of lightning.
- This Is a Drill: The Mech he pilots is armed with an electrified one.
- Villain Team-Up: Had one with Bowser before the events of the battle, but as it turns out, he secretly developed his Battle Egg Mech V1 to defeat not only Mario and Sonic, but Bowser as well to take over his Kingdom and make it part of Eggmanland.
Deadpool vs. Deathstoke
- Badass Boast: "Oh, I'm gonna have fun tearing you apart!"
- Guns Akimbo: BUUUUUUUUUUULLEEEEEEEEEEEEEETS!
- Improbable Weapon User: Weren't expecting me to go all Chun-Li and use my couch as a weapon, were ya?
- Ludicrous Gibs: I got blasted by Stroke's Sniper Rifle, this forced me to forfeit the match and give ol' one-eyed Bart the victory. Ah, well, at least I killed him in the main show. All he did was knock me out of commission for a bit.
- Losing Your Head: The good thing about healing factors is, they let you survive even when said Rifles have blown you to bits!
- Badass Boast: "That's what I came here for. And you and I know damn well that I'm not leaving without it."
- Catch and Return: Throws one of Deadpool's Grenades back at him before before kicking him away just as it explodes.
- Dynamic Entry: Drops into the building via helicopter, before exploding open the door to Deadpool's lair.
- Guns Akimbo: Much like in their actual Death Battle, uses this to stop Deadpool's bullets in mid-air.
- Ludicrous Gibs: Blasts Deadpool to pieces with his Sniper Rifle to take the win. Deadpool's head survives, but for added insult to injury, he kicks it away like a football.
- Pistol-Whipping: Clubs Deadpool several times with his Sniper Rifle in between shooting him.
- Stone Wall: His armor helps him to tank barrages of bullets.
- Sniper Rifle: Is able to shoot Deadpool with it multiple times whilst throwing it, and is eventually able to use it to blow the Merc With the Mouth to pieces for the win.
- Telescoping Staff: One of his signature weapons. In the fight itself, he throws it like a boomerang, hitting Deadpool multiple times.
Dante vs. Ragna the Bloodedge
- Forgot About His Powers: You'd think he'd try to use his devil powers at some point during the battle to even the odds.
- Guns Akimbo: Ebony and Ivory, of course.
- Opening a Can of Clones: The skill-set this Ragna has seems to indicate it's not the original Ragna. He's found by Dante surrounded by three defeated Hakumens, presumably clones as well. Judging from the green, red, and blue lights he absorbed from the defeated Hakumens, he got the copies by beating them.
- Palette Swap: This Ragna has light-blond hair and white clothes, possibly to help distinguish Ragna from Dante, since they both have white hair and wear red.
- Single-Stroke Battle: How he ends the fight after using the Azure Grimoire.
Mewtwo vs. Frieza
- Ambiguous Gender: Like most legendary Pokémon, it has no actual gender- although there have been both masculine and feminine depictions of the character.
- Barrier Warrior: Barrier/Protect. It does do a good job of stopping Frieza's Death Bullets, but Frieza warps around it and attacks Mewtwo directly instead.
- Blood Knight: Due to being engineered to be the ultimate Pokémon, it enjoys fighting and shows little restraint against opponents.
- Casting a Shadow: Shadow Ball.
- Catch and Return: Mewtwo stops one of Frieza's Ki Blasts and fires it back at him- although this mostly serves just to anger him enough to use the Death Ball on it.
- The Cameo: It later makes an appearance in Mbison vs. God Rugal, where it's seen clad in its Team Rocket armor from Pokémon: The First Movie and floating in a stasis tube in the laboratories of Shadaloo. Given the circumstances, it's very likely that Shadaloo captured and modified it after it was defeated by Frieza.
- Kill It with Fire: Is charred by Frieza's Death Ball- although because it does remain in one piece afterwards with no blood or anything, it's not made explicitly clear whether or not it actually died or simply fainted like in its own series.
- Overshadowed by Awesome: Mewtwo is one of the strongest Pokemon in existence, but even with this, every Pokémon is weak compared to Frieza's planet-destroying power. It still puts up a fight, though.
- Mind over Matter: One of the most powerful Psychic Pokémon around, and makes use of its power by ripping up a series of large boulders from the ground and hurling them at Frieza.
- Psychic Powers: Psychic-type.
- Spanner in the Works: Mewtwo comes out of nowhere just as Frieza's got all the Dragon Balls. Too bad he couldn't do much against him.
- Ultimate Life Form: Designed by scientists on Cinnabar Island to be the most powerful Pokémon in the World.
- The Bad Guy Wins: Unless somebody stole the Dragon Balls while Frieza was distracted with Mewtwo.
- Beam Spam: Briefly loses his temper at Mewtwo's shield. He then teleports around it and just kicks him in the face.
- Kill It with Fire: How he finishes off Mewtwo, though it's unclear whether or not he actually killed Mewtwo or simply knocked it out.
- Pre Ass Kicking One Liner: "You will be killed by me!"
Sakuya Izayoi vs. Dio Brando
- Awesomeness by Analysis: Most people are incapable of seeing Stands, Sakuya included. This doesn't stop her from blocking The World's Rapid-Fire Fisticuffs with a barrier and then cutting off its arm after reading the next attack.
- Flechette Storm: Her specialty is throwing knives. Lots of knives at the same time, in fact.
- Ninja Maid: She is a maid, and is quite capable of kicking ass.
- Pinball Projectile: Her knives can bounce off the ground. Most notably used in the finale, where a single knife rapidly bounces around to constantly hit Dio before it pierces right through him.
- Pummel Duel: Happens right in the beginning, with Sakuya using Blade Spam to counter Dio's Rapid-Fire Fisticuffs.
- Red Eyes, Take Warning: After Dio tries to crush her with a bus, her eyes turn red for a short while and she gets serious.
- Time Stands Still: Can freeze time for extended amount of time. This, combined with Dio's time-freezing powers, allowed the battle to drag pass the minute mark.
- Wrestler in All of Us: At one point, she does a German Suplex at Dio, followed up with a dropkick.
- An Arm and a Leg: Both he and The World gets their left arm chopped off at one point. He attaches it back, though not before bashing Sakuya with it.
- Back for the Dead: Returns in "Jotaro Kujo vs. Kenshiro", only to be defeated by Kenshiro before the actual fight starts.
- Car Fu: Attempts to kill Sakuya with a bus before the fight begins and later attempts finish her off by crushing her with his iconic steamroller. While it looks like it worked at first, she managed to get out from under it before it did.
- Fighting Spirit: His Stand, The World.
- Hoist by His Own Petard: Dio's infamous steamroller attack actually pushed the Luna Dial clock towards the time-frozen Sakuya, which allowed her to get the upper hand.
- Not Quite Dead: He's revealed to have survived in "Jotaro Kujo Vs Kenshiro".
- Pummel Duel: Happens right in the beginning, with Dio using The World's Rapid-Fire Fisticuffs to counter Sakuya's Blade Spam.
- Rapid-Fire Fisticuffs: Mainly from The World, but he also does it, mainly to pummel a bus and a steamroller until they explode.
- Small Role, Big Impact: He gets quickly offed before Jotaro and Kenshiro fought, but he's the reason why the two started fighting.
- Time Stands Still: The World allows him to freeze time. This, combined with Sakuya's time-freezing powers, allowed the battle to drag pass the minute mark.
- Worthy Opponent: Gives Sakuya "a little credit" when he thinks he's killed her. Unfortunately for him, she wasn't done just yet.
- Wounded Gazelle Gambit: Pretended to be dead until he could find someone to suck dry and heal his wounds. He would've succeeded, if not for the fact that he ran into Kenshiro, of all people.
Dan Hibiki vs. Hercule Satan
- Adaptational Badass: Thanks to the "No research" part of One Minute Melee, Dan, despite losing, ends up doing far better against Hercule here than in his Death Battle match. Dan is able to pull off a Haoh Gadoken that doesn't dissipate and is able to blow up a car and even pulls off legitimate Ansatsuken moves like the Hadouken and Tatsumaki Senpukyaku. Towards the end of the battle, he is able to grab Hercule's arm and was prepared to deliver the finishing blow. It's Hercule tricking him into accepting an explosive as a gift and then clumsily tripping over it when he tries to get away that does him in.
- Kamehame Hadoken: Blows up a car with Haoh Gadoken.
- Paper Tiger: Tries to bluff his way out of the fight by intimidating Hercule, who's doing the same thing. Their escalating bluffs eventually lead to them fighting.
- Pink Is for Sissies: Hercule calls Dan a "pink pajama-wearing monkey".
- Pyrrhic Victory: Lost the fight, but his unconscious body falls on and knocks Hercule out afterwards.
- Afro Asskicker: Completely outclassed in his home series, but he does pretty good against a dude who can shoot lasers from his fists here.
- Jet Pack: Uses it to travel quickly and give his stronger attacks a needed boost.
- Paper Tiger: Dan tries to bluff his way out of the fight by intimidating Hercule, who's doing the same thing. Their escalating bluffs eventually lead to them fighting.
- Pyrrhic Victory: Beats Dan, but suffers a head injury from his falling body. Still gives the fans a thumbs up at the end.
- Throw Down the Bomblet: Uses stink bombs and explosives disguised as handheld game consoles.
- Worth It: Given his track record against opponents with Ki abilities, his win, Pyrrhic or otherwise, is still something to cheer about.
Lucario vs. Renamon
- Aura Vision: Can see the Aura of others, which he uses to sense Renamon's location.
- Berserk Button: Attacks Renamon for disturbing his deceased owner's resting place.
- Cross Counter: Gets into one with Renamon at the very end. It results in a Double KO.
- Didn't See That Coming: His reaction to the Double KO.
- Improbable Weapon User: Uses bones as clubs as part of his Bone Rush attack.
- Insistent Terminology: Corrects Renamon calling him a dog. He's actually a Jackal.
- Ki Manipulation: Wields the power of the Aura.
- Status Buff: Uses Sword Dance to power himself up during a lull in the fight.
- Asian Fox Spirit: She's a bipedal fox with supernatural powers, though she doesn't have multiple tails outside her Champion form.
- Blood Knight: Came to Sir Aaron's grave specifically to fight the "powerful spirit" she sensed there, Lucario.
- Catch and Return: Catches one of Lucario's bones and sends it back at him.
- Cross Counter: See Lucario's profile above.
- Flechette Storm: Her main attack, Diamond Storm, launches a barrage of glowing white razor-sharp leaves.
- Kick Chick: She has a feminine voice and persona, despite Digimon technically being agender. And she uses a lot of kicks.
- The Empath: Could sense Lucario's spirit, leading her to him, and could tell he was 'troubled'.
Samus Aran vs. Mega Man
- Adaptational Villainy: In canon, Samus would never normally attack fellow heroes without good reason to. Subverted when it turns out that it's not actually her, but the SA-X impersonating her. The real Samus shows up in the climax to rescue Mega Man and help him put it down for good.
- Big Damn Heroes: The real Samus Aran shows up to rescue Mega Man from SA-X at the climax- strafing it with cannon fire from the Gunship, and then leaping down from it to help him finish it off.
- Buried Alive: The skyscraper the two were fighting in collapses on top of SA-X Samus after her initial defeat, due to the Black Hole Bomb she was knocked into detonating and destroying its foundations. It's not there long, however.
- Cool Ship: The Gunship. The real Samus Aran uses it to rescue Mega Man from the SA-X at the climax by blasting it with its cannons when it has him down, before flying off in it after the fight is over.
- Evil Counterpart: The Samus that Mega Man defeats is actually SA-X. The real Samus shows up to help him finish the job.
- Grappling-Hook Pistol: The Grapple Beam, which Samus uses to capture Mega Man and throw him around. This is eventually turned against her when Mega Man sees it coming and catches the beam.
- Leitmotif: A metal remix of the Ridley boss theme from Super Metroid. When the real Samus shows up to rescue Mega Man from SA-X, it changes to Theme of Samus Aran: Space Warrior from Super Smash Bros. Brawl.
- Macross Missile Massacre: Uses a more low-key missile barrage assisted by an extended beatdown- firing off several as she uses the Speed Boost to first outrun them, and then forces Mega Man into him as she's comboing him.
- No-Holds-Barred Beatdown: Extremely vicious towards Mega Man in the fight. Turns out it's actually SA-X who's been fighting him the whole time.
- One-Winged Angel: SA-X reveals its true monstrous nature after its "defeat".
- Out-of-Character Moment: As stated under Adaptational Villainy, Samus would never normally attack fellow heroes such as Mega Man. Subverted however, as the one trying to destroy Mega Man turns out to be the SA-X. The real Samus shows up after the initial battle to lend a hand in putting it down for good.
- Power of the Void: The SA-X Samus is "defeated" by being sucked towards an activated Black Hole Bomb before being blasted fully into it by a Charged Shot, causing it (And the building the two were fighting in) to explode with her in it. Then the One-Winged Angel shows up.
- Super Speed: Shoulder-tackles Mega Man very hard early on using the Speed Boost, as well as using it to outrun her own missiles so she can knock Mega Man into them.
- Spin Attack: The Screw Attack.
- Sprint Shoes: The Speed Boost- which she uses early on to shoulder-tackle Mega Man and outrun her own missiles to kick him into their path.
- Un Sound Effect: After the SA-X's final form is blown to pieces by Samus and Mega Man's combined Zero Laser and Mega Legends. What's its dying noise? "Ech".
- Wave-Motion Gun: Zero Laser. Uses this with Mega Man's Mega Legends to kill the SA-X at the end.
- Attack Reflector: The Skull Barrier, which he uses to send a charged shot back to the SA-X Samus.
- Awesomeness by Analysis: Samus hits him with a massive combo that makes use of almost her full arsenal right off the bat, but after he heals up, Mega Man is able to analyze each type and perfectly counter them the second time around. He might not have lasted long enough to put it into practice if an E-Tank hadn't fallen on his head, though.
- Badass Adorable: Looks and behaves like a 10-year old boy, but still able to kick ass like nobody's business.
- Big Damn Heroes: Rush saves him from being sucked into the same Black Hole Bomb that initially defeated the SA-X version of Samus.
- Catch and Return: After initially being slammed around by it, Mega Man catches Samus's Grapple Beam in mid-shot and uses it to pull her towards him and land a Mega Upper. Later on, he also kicks a Missile back at her in free-fall.
- Evil-Detecting Dog: Rush lets Mega Man know that Samus, or rather, SA-X, isn't down for the count just yet.
- Leitmotif: Mega Man 2 Medley, from Super Smash Bros. 4.
- Mid-Battle Tea Break: Uses an E-Tank partway through the fight to recover some of his health after being repeatedly slammed into the ground and thrown through a building by Samus's Grapple Beam.
- Pint-Sized Powerhouse: Only 132 cm (4'4") tall and has the appearance and AI age of a 10-year old boy, yet he's still able to fight on equal terms with one of the most feared bounty hunters in the Galaxy.
- Power Copying: One of his standard abilities, and whilst he does not use the ability itself against Samus, it does allow him to use the various Special Weapons of the Robot Masters he has previously beaten.
- Power of the Void: Initially defeats the SA-X version of Samus by blasting her into an activated Black Hole Bomb with the Charge Shot, causing it (Along with the building the two were fighting in) to explode with her in it as he escapes via Rush Jet.
- Primary-Color Champion: There's a reason they call him the Blue Bomber.
- Ridiculously Human Robot: One of the original Robot Masters made by Doctor Light.
- Reference Overdosed: As shown below (See Walking Armory.), the Blue Bomber uses at least one Robot Master weapon from each of the first nine Mega Man games, including Mega Man & Bass (and possibly Marvel vs. Capcom, if the uppercut he used is supposed to be the Mega Upper).
- Robot Dog: Rush initially accompanies him into battle and not only rescues him from being sucked into the Black Hole Bomb that Mega Man had already knocked Samus into, but also gives him a warning that the SA-X Samus isn't quite defeated yet.
- Shoryuken: The Mega Upper.
- Super Strength: Provided by Guts Man's Super Arm.
- Unrealistic Black Hole: The Black Hole Bomb. He is able to use it right at the end of the initial battle to defeat SA-X Samus, although it does cause the building they're fighting in to collapse and almost sucks Mega Man in himself, although he is saved by Rush in his Rush Jet form.
- Walking Armory: Much like in Super Smash Bros. 4, Mega Man uses a whole bunch of weapons in this fight, including a few (Knight Crusher, Thunder Bolt and Spread Drill) that he to date, hasn't used in the fighting games he has appeared in. Among these are:
- His standard Mega Buster and Charge Shot.
- Super Arm (Guts Man)
- Metal Blade (Metal Man)
- Air Shooter (Air Man)
- Crash Bomber (Crash Man)
- Hard Knuckle (Hard Man)

Sonic the Hedgehog vs. The Flash
Sonic The Hedgehog
- Adaptational Villainy: Much like with Zero killing Meta Knight earlier on in the series, Sonic comes off as massively out-of-character to the point where he almost seems evil- with not only how he ends up straight-up murdering the Flash, but also with how eerily OK he is with it afterward.
- Big Brother Instinct: As soon as he saw Flash "bullying" his friends, there was hell to pay.
- Bond One-Liner: "You deserve that for hurting my friends".
- Disproportionate Retribution: Straight-up murders a fellow hero and quips that he "deserved it" for fighting his friends, who are heavily implied to have attacked him first, no less.
- Kung-Fu Sonic Boom: The end result of his Super-Sonic-outer-space dropkick when he snaps The Flash's neck.
- Out of Character: Intentionally and brutally murdering someone for fighting his friends and saying they deserved it afterwards makes Sonic come off as unusually sociopathic- more along the lines of Shadow or Omega than himself.
- Rolling Attack: The classic Spin Dash.
- Speed Blitz: This was inevitable against someone like The Flash.
- Super Mode: Super Sonic. It's what clinched the match.
- Super Speed: Fastest thing alive. And still is after killing The Flash.
- Took a Level in Jerkass: As impulsive and arrogant as Sonic is supposed to be in his own series, he comes off as outright evil here, with regards to how he straight-up murders the Flash (A fellow hero) and says that he "deserved it" afterwards.
- A Tragedy of Impulsiveness: He got into a fight against Sonic because Tails and Knuckles attacked him first and he defended himself. This gets him killed.
- Fragile Speedster: Even Sonic has trouble landing a solid hit on him, but each one leaves him reeling.
- Neck Snap: On the receiving end thanks to Super Sonic.
- Rapid-Fire Fisticuffs: His main method of attack throughout the fight.
- Speed Blitz: Again, inevitable against someone like Sonic.
- Super Speed: One of the fastest beings in the DC Universe and capable of keeping up with Sonic with ease until he goes Super Sonic.
Catwoman vs. Black Widow
- Classy Cat-Burglar: The fight begins when Black Widow interrupts a typical job for her.
- Dodge the Bullet: Barely avoids Black Widow's sniper fire.
- Grappling-Hook Pistol: Used to move their fight to the top of the roof.
- Kick Chick: Kicking is her favorite way of combat.
- No-Holds-Barred Beatdown: Once she dodges Widow's sniper shot, the remaining time is spent watching Catwoman wail on her with punches, kicks, claws and whip.
- Supermodel Strut: Her walking animation before the fight has her doing a deliberately sexy strut while swinging her arms and hips.
- Whip of Dominance: Her weapon of choice is a bullwhip, and her costume has the dominatrix motif that she's known for.
- Combat Pragmatist: Has no qualms using a sniper rifle or a smoke grenade to even the odds with Catwoman. She even uses the briefcase Catwoman stole to pummel her!
- Grappling-Hook Pistol: Used to move their fight to the top of the roof.
- The Gunslinger: Uses two pistols and a sniper rifle.
- Made of Iron: In an apparent Shout-Out to Mortal Kombat's X-Ray Attacks, Catwoman fractures her skull and spine, but not even that keeps her down.
- Navel-Deep Neckline: It goes all the way down to the bottom of her sternum.
- Throw Down the Bomblet: Uses a gas grenade to get in some hits on Catwoman.
- Wrestler in All of Us: Performs a German Suplex on Catwoman.
Ben Singer vs. Craig Skistimas
- Mean Character, Nice Actor: While OMM's depiction of Ben is a total jerk, the real Ben Singer is a pretty nice guy. He's appreciative of all his fans, and even if someone disagrees with him, he's still respectful to them.
- Small Name, Big Ego: Is parodied as this. If you disagree with him, too bad.
- Audience Surrogate: for fans pissed off with the outcome of the Goku Vs. Superman Death Battles.
- Back from the Dead: Ben finished him off Mortal Kombat X-Ray style. Lucky for Craig, a bunch of health packs were near by, reviving him.
- Bad Boss: In the episode, he goes to talk to Ben about Death Battle because of upset fans. If you piss him off...
- No-Holds-Barred Beatdown: He delivers one on Singer just before the fight is Cut Short.
- Screaming Warrior: He screams a lot during the actual fight.
