Main Fighters

  • Alien Hair: All female fighters (except Mechanica and Dr. Coyle), as well as Misango, have hair that matches the material their ARMS are made of.
  • Ensemble Cast: Even though by means of marketing, the game's leads are fairly obviousnote , Mr. Yabuki is on the record of considering there to be no main character — or rather, in his words, "everyone's the protagonist".
  • Exotic Eye Designs: Each human fighter has a spiral pattern to their pupils. Likely a side effect of whatever it is that gave them their ARMS, as Mechanica, the only human without the ARMS power, has normal eyes.
  • Home Stage: Every fighter in the game has their own stadium, explained below.
  • Just Woke Up That Way: Similarly, all human fighters simply had ARMS one day when they didn't the day before, excluding Mechanica. Dr. Coyle is another exception, though, in that she gave herself ARMS, their unique nature as coils around a solid arm a visual indicator.
  • Kayfabe: As can be expected from a professional combat sport, even in a fantastical setting, most of the cast are playing up a persona, albeit for many informed by genuine personal motivations. Even though the likes of Master Mummy and Kid Cobra play up the Heel angle, they're all actually very affable people.note 
  • Mask of Power: All the fighters part of the ARMS phenomena wear masks. This accessory puts the wearer's ARMS into the battle-ready coiled form. When the masks are off, then the arms, hair, etc. of focus behave normally.
    • As shown in the FCBD comic, they also acts as power regulators since ARMS tend to randomly manifest even without the masks, putting the masks on gives back control.
  • Multi National Team: Min Min seems to be Chinese, Ninjara Japanese, Twintelle French and Lola Pop Italian. By virtue of being a Mummy, Master Mummy may be Egyptian. Spring Man's home stage bears an uncanny resemblance to New York. Along with Max Brass, he's one of the few with an American accent (Max's trailer also makes use of red, white, and blue rings to introduce him). Ribbon Girl and Mechanica both mostly speak in English phrases with heavy Japanese accents, Misango speaks Japanese with a Latin American accent and Dr. Coyle seems to have a mild Australian accent, despite speaking American English.
  • Palette Swap: Each character has 4 color schemes they can go with. Their fans will match their outfit accordingly.
  • Personality Powers: The form that a person's ARMS take tie into something most significant towards them, and may change accordingly. For example, Word of God states that Max Brass' ARMS became a championship belt motif as a result of being champion for so long.
  • Pokémon Speak: Spring Man, Ribbon Girl, Mechanica, Min Min, Twintelle, Byte, and Kid Cobra have a habit of saying their full name or a part of it on the character select screen, within matches and on their Win screens.
  • Puberty Superpower: ARMS usually manifest in teenagers at night or upon waking. Considering Mechanica is still in her mid teens, she may actually still have a chance at natural ARMS someday. Kid Cobra averts this by being born with the ARMS ability, which is apparently extremely rare.
  • Rapid-Fire Fisticuffs: All fighters possess the ability to do a Rush, which turns their ARMS' recoil into a hail of punches. Mind, this varies in capability depending on the ARM and the fighter.note 
  • Super Strength: Everyone, even scrawny characters like Kid Cobra and Byte, can lift heavyweight fighters like Master Mummy and Max Brass.
  • Weapon of Choice: Each fighter has three signature ARMS associated with them, though they are able to use the ARMS of fellow combatants if unlocked.

    Spring Man 

Spring Man
The Bouncer
Voiced by: Peter Von Gomm

A balanced fighter whose ARMS take the shape of springs. He's hot-blooded and has a strong determination to win. His unique traits are that he can repel punches while charging with a shockwave, and that once he hits critical health, his ARMS will stay charged.

  • The Ace: Coyle's notes on Spring Man reveal that many consider him to be the best in the league, and she seemed to concur with the notion.note  When the world's authority on all things ARMS shares the notion, you know it has grounding.
  • All-American Face: His physical body closely evokes shades of Little Mac, a native New Yorker, his home stage of Spring Stadium is in what closely resembles a downtown of that very city, and his color scheme is red, white and blue.
  • Attack Reflector: Downplayed with his mini-shockwaves.
  • Battle Boomerang: His Boomerang ARMS, naturally.
  • Big Eater: His bio says he can eat 12 pizzas in one sitting.
  • Big "WHAT?!": It is one of his reactions when his shield breaks. This is also his reaction to Dr. Coyle delivering Max Brass a Curb-Stomp Battle in Grand Prix mode at level 6 or 7.
  • Blow You Away: His secondary Boomerang ARMS are Wind-elemental.
  • Color-Coded Characters: Blue and magenta-ish red.
  • Comeback Mechanic: When he's low on health, his sheer determination causes his punches to be permanently charged. He ain't called "The Comeback King of Spring" for no reason.
  • Critical Status Buff: When his health gets low, all of his attacks become charged attacks.
  • Crouching Moron, Hidden Badass: Described in his bio as a goofy guy off the ring, but a force to be reckoned with in the ring.
  • Delinquent Hair: While he himself isn't a delinquent, his spring-like hair is reminiscent of a typical pompadour worn by Japanese Delinquents.
  • Eagleland: Type 1. He's the ideal American to the core—well meaning, hard working, able to rise to the top, and a hearty eater.
  • Face: While all the fighters have a fair share of fans he is likely this to Master Mummy's and/or Kid Cobra's Heel.
  • Friend to All Children: The 5/17 Directs mentions he's popular with kids. One piece of production art even shows him keeping a young fan out of harm's way when he fails to Look Both Ways before getting his hat back.
  • The Hero: More or less the main character of the game, with a Stock Shōnen Hero personality to boot.
  • Home Stage: Spring Stadium is his home arena.
  • Improbable Hairstyle: It might be possible to replicate the major portions of his pompadour if one had the hairstyling skills, but probably not the spring-shaped sideburns he also sports.
  • Jack-of-All-Stats: He's said to have more balanced abilities than the other fighters.
  • Legacy Character: He's the third person to hold the name of Spring Man.
  • Leitmotif: A more intense arrangement of the main ARMS theme, fitting for the Series Mascot.
  • Mascot: The Free Comic Book Day preview of his story reveals that "Spring Man" is the mascot of Spring Gym, and a widely respected title. Our Spring Man had to test as one of 600 applicants to apply for the role.
  • Mundane Utility: One piece of official artwork shows him extending an arm in order to reach and change the TV channel.
  • Pink Girl, Blue Boy: Downplayed example with Ribbon Girl, as he also wears a magenta-ish red color.
  • Playing with Fire: His default and picturesque ARMS are the Toasters, gloves that engulf his punches in flame when charged. Oddly fitting for a Hot-Blooded guy like him.
  • Power Fist: His primary Toaster ARMS are glove-type weapons.
  • Primary-Color Champion: More or less the main character of the game, he's primarily colored blue and red.
  • Saying Sound Effects Out Loud: He will often shout out some of the violence-related words, regardless if he finishes off the opponent or not. Whatever if he says "Pow!" when throwing his opponents or "Boi-oi-oing!" when jumping off of the Mausoleum trampolines can be at least random when he says something.
  • Screams Like a Little Girl: In the yelping sense. This sometimes happens when he's grabbed and/or thrown in the air.
  • Series Mascot: A spot he seems to share with Ribbon Girl, as they were the first two characters revealed and they've both been heavily featured in all of the game's promotional material so far.
  • Shoryuken: His grab attack involves setting up the victim with an uppercut, then following with a dragon punch with his opposite hand. Coincidentally, this makes it similar to Ryu's Shin Shoryuken.
  • Spirited Competitor: As his bio indicates. He was literally drooling at the idea of fighting in Smash Bros.
  • Spread Shot: His tertiary Tribolt ARMS are a horizontal-type multi-shot weapon.
  • Spring Coil: Has this as a motif, from his swirly pompadour to his spring-like arms.
  • Stock Shōnen Hero: His bio says that he's a bit of a goofball, but trains incredibly hard to reach the champion's belt. He can even make a comeback through sheer determination alone! And like many characters of this type, he's quite the Big Eater; able to eat 12 pizzas in one go!
  • To Be a Master: Like your typical Stock Shōnen Hero, he wants to be the very best, like no one ever was.
  • Too Many Belts: The visual in his ending shows a bunch of belts being worn around his arms- likely in motivation of wearing the Champion's Belt.
  • Totally Radical: He considers his arms to be "rad".
  • Trademark Favorite Food: Pizza according to his official profile. He can eat 12 pies in one go even! A piece of official artwork even shows him enjoying a slice.
  • Up to Eleven: His love of pizza. Take a look at his profile; it's listed as a hobby. No, not "eating pizza", just straight-up "pizza". Even Min Min doesn't take it that far.note 
  • Unusually Uninteresting Sight: Subverted, as Spring Man was by his own volition fairly freaked out at his mutation, but he took to it pretty quickly.
  • Visual Pun: He's a Stock Shōnen Hero who, when defeated, springs back into action.
  • You Gotta Have Blue Hair: Spring Man has his hair in a light blue swirl.

    Ribbon Girl 

Ribbon Girl
The Airess
Voiced by: Momoka Kawasaki

An agile fighter with ribbon ARMS who's also an Idol Singer. Her unique traits are that she can jump four times consecutively, air dash twice in a row, and that she can fast-fall to the ground which charges her ARMS instantly.

  • Alien Hair: It's hard to tell unless you're looking closely, but Ribbon Girl's hair is also made of ribbons.
  • Blow You Away: Her secondary Popper ARMS have the Wind element.
  • The Cheerleader: The inspiration for her clothes.
  • The Chick: The female foil to The Hero, and the most feminine and spirited fighter as a cheerleader.
  • Color-Coded Characters: Pink and bright yellow.
  • Combat Stilettos: Wears heeled boots while fighting as seen in this official art.
  • Distaff Counterpart: Downplayed when it comes to Spring Man. While she is the female lead of the game opposite Spring Man, her abilities are completely different from his.
  • Double Jump: She can jump in the air four times.
  • Girly Girl with a Tomboy Streak: Pretty girly but into martial arts. She also got a Not-So-Tomboyish Ponytail.
  • Hair of Gold, Heart of Gold: Her blonde "hair" resembles a single ribbon.
  • Home Stage: Ribbon Ring is her home arena.
  • Human Hammer-Throw: Her grab attack has her spin around with the opponent once before throwing them.
  • Idol Singer: She likes to sing, and is described as "the pop star of the ring." Her home stage, Ribbon Ring, visibly takes place on a concert stage.
  • Improbable Hairstyle: Her hair is as ribbon-like as her ARMS.
  • Leitmotif: A techno-pop song with Ribbon Girl singing along to the music.
  • Magic Music: She can be heard singing a note, surrounding herself with a ring of musical notes, when using her extra jumps.
  • Modesty Shorts: Wears these to avoid having a Magic Skirt.
  • Not the Fall That Kills You…: Ribbon Girl's grab attack damages opponents when they're knocked to the ground, since she throws them to the side after grabbing them instead of hitting them.
  • Pink Is Feminine: She's decked out near-completely in pink and looks girly.
  • Playing with Fire: Her tertiary Slapamander ARMS are fire-elemental.
  • Power Fist: Her primary Sparky ARMS are glove-type weapons.
  • Pungeon Master: Makes a lot of puns out of her name, such as "Ribbonado!" when she executes a throw, or "Ribboh-no!" when she's knocked off her feet.
  • Regal Ringlet: Her ponytail.
  • The Rival: In virtually every piece of advertisement they're featured in, she's throwing down with Spring Man.
  • Series Mascot: She was revealed alongside Spring Man, and has been featured just as heavily in most videos about the game.
  • Shock and Awe: Her default ARMS, Sparky, give her punches an electrical current when charged.
  • Weight Woe: Her weight is listed as "No comment".
  • Whip It Good: Her Slapamander ARMS work as a whip.
  • Why Did It Have To Be Lightning?: If you have Springtron to pit against Ribbon Girl in the Grand Prix, it is revealed that she is ironically afraid of lightning. Biff even questioned why she is carrying Sparky, her primary ARM in the first place.
  • You Gotta Have Blue Hair: Ribbon Girl looks like a downplayed example, having blonde hair with a green stripe through it, until you realize her hair is made out of ribbons.
    • One of her alt colors does count though, which is colored blue.


The Student of Stealth
Voiced by: Kenji Takahashi

A student ninja who fights with chain ARMS. His unique traits are that he can warp short distances while air-dashing and he can teleport to the side while blocking attacks.

    Master Mummy 

Master Mummy
The Grim Creeper
Voiced by: Kouji Takeda

A massive mummy who can extend his punches with his bandages. He does not flinch from weak ARMS punches, and his unique trait is that he can regain a bit of health when he guards.

  • Alliterative Name: Master Mummy.
  • Amazing Technicolor Population: His skintone is uniquely purple.
  • Back from the Dead: Biff mentions he woke up in a mausoleum which is later revealed to have been the fault of Coyle's experiments somehow.
  • Battle Boomerang: His Phoenix ARMS, despite being bird-shaped, essentially act like one.
  • The Big Guy: The largest, strongest, and meanest looking of them all, but has a soft spot for his family.
  • Big Ol' Eyebrows: Has two bandages above his eyes that resemble this.
  • Chummy Mummy: Sure, he's big, scary looking, and fights just as hard as the other fighters, but he cares for his family, is cool with his fans, and is a sensitive guy overall. Not so much when he gets in the ring; this is a fighting game, after all.
  • Color-Coded Characters: Mainly purple and white.
  • Conlang: If you look closely the bandages that make up his ARMS are covered with this style of writing. With his status of being some thousands of years old they're probably this game's take on hieroglyphics (Or simply the game's unique written language in general).
  • Earn Your Happy Ending: His post-credits visual shows him with his family as they get interviewed by Biff.
  • Family Man: According to his profile, he loves his family, but their location is unknown. He's been searching for them ever since he woke up.
  • Gatling Good: His Retorcher ARMS act as a slow-firing machine-gun.
  • Gentle Giant: He loves his family and has shown below he also cares about his fans given the fact he has at least rescued a young boy's balloon from floating away (which makes a bit of sense given when we see his family in the ending it consists of just himself, his wife, and their child). Biff also refers to him as being rather sensitive when he's Coyle's opponent.
  • The Giant: Is the tallest fighter of a consistent height at 7'6". (Helix can occasionally beat him due to the fact that the tallest he can stretch is 8'2".)
  • Guttural Growler: Fitting for his undead status and large size, the noises he tends to make fall into this nature.
  • Heel: He's pretty big and scary in the ring, so one would assume him as a villain, but it turns out he's a friendly guy otherwise. His favorite thing is his family, and he also cares about his fans.
  • Home Stage: Mausoleum is his home arena.
  • Huge Guy, Tiny Girl: As seen in his ending, he utterly dwarfs his wife in size.
  • Immune to Flinching: He doesn't flinch from weaker attacks.
  • Leitmotif: Ominous and creepy rock for the ominous and creepy mummy.
  • Meteor Move: His grab attack has him slam the opponent into the ground with his outstretched ARMS.
  • Mighty Glacier: He is the largest and heaviest character in the starting cast of the game, and by that token, one of the slowest. While his large size and low mobility doesn't do him much favors in avoiding punches, he makes up for it with his powerful punches, the strongest grab attack of the fighters, and the ability to regain health while defending, giving him both offensive and defensive strengths.
  • Mummy: Master Mummy is well, a mummy, complete with bandages for ARMS.
  • Non-Elemental: His signature Megaton ARMS do not have any special attributes, unlike the other two starting ARMS available to him (Retorcher and Phoenix) which use fire.
  • Playing with Fire: His secondary Retorcher and tertiary Phoenix are both fire-elemental.
  • Purple Is Powerful: Has dark purple skin, his small bit of clothing, the writing on his ARMS, and even some of his main equipment choices belong to the color family. Definitely is on the strong side.
  • Red Eyes, Take Warning: A muscular mummy who can pack a punch.
  • Regenerating Health: He regains health when blocking.
  • Rule of Three: His family is him, his wife, and their child which totals to this number.
  • Spike Balls of Doom: Downplayed with his signature Megaton ARMS, which appear to have blunted spikes all over them.
  • Ugly Guy, Hot Wife: He's not exactly ugly, but he's not that much of a looker. His wife, by contrast, is beautiful despite also being a mummy.
  • Vague Age: Master Mummy's age is unknown. Given that he's a mummy, it's likely in the millennia.

    Min Min 

Min Min
The Ramen Bomber
Voiced by: Haruna Takatsu

A martial artist with noodle ARMS who serves as the poster girl for her family's ramen shop. Her unique trait is that she can deflect attacks while dashing with her kicks, even in mid-air. Her left arm can turn into a dragon after a long charge or successful throw and can stay charged until knocked down.

  • Alien Hair: Her hair may look like a blonde bob cut at first glance, but it's actually made of noodles!
  • Animal Motifs: While Min Min's arms are noodles by default, one of them can take the form of a dragon. Elements of this dragon theme can also be spotted in her shorts and shoes through texture and design.
  • Anime Chinese Girl: She's Chinese-inspired, loves noodles, and incorporates kung fu into her fighting.
  • Bilingual Bonus:
    • Her Chest Insignia is a stylized version of "麺", the Japanese kanji (and traditional Chinese character) for noodles.
    • While her given name in English is "Min Min", the Japanese pronunciation takes care to add a separate sound to her name, making it sound more like "miàn miàn", the Chinese word for noodles that would evolve into "ramen".
    • Her attack call-outs and victory lines are in Chinese as well:
      • "好吃!" (Hǎo chī!) - "Yum!"
      • "我愛拉麵!" (Wǒ ài lāmiàn!) - "I love ramen!"
      • "谢谢!" (Xièxiè) - "Thanks!"
  • Blush Sticker: More noticeable in close-ups, like during character selection menu and in her victory poses.
  • Breakout Character: If winning the Party Crash Bash tournament didn't solidify her as this, then becoming the playable ARMS representative for Super Smash Bros. Ultimate certainly did. Even ARMS producer Kosuke Yabuki loves her, and personally recommended Min Min to join Smash.
  • Color-Coded Characters: Orange, with a bit of green.
  • Edible Bludgeon: The fact her arms are made of ramen brings a literal take to being a noodle person.
  • Energy Weapon: If equipped with the Dragon ARM, she can blast laser beams.
  • Hartman Hips: Her hips are very wide, maybe even wider than Twintelle’s hips given her looser clothing. Probably from all the ramen.
  • Home Stage: Ramen Bowl is her home arena. note 
  • Improbable Weapon User: Min Min's arms and hair are made out of ramen noodles.
  • Kick Chick: She's the first character shown to have the ability to kick, which she uses to deflect her opponent's attacks.
  • Leitmotif: Classical Chinese instruments mixed with a strong techno beat.
  • Mukokuseki: Despite being Chinese-influenced in appearance and her costume's design, she looks like a blonde thanks to her noodle hair.
  • Meaningful Name: Min Min seems to have a Theme Naming for her love of ramen in general. In the Japanese sense, her Japanese name is actually a transcription of "Miàn Miàn", which means "Noodle Noodle" in Chinese.
  • My Nayme Is: Her name is pronounced Men Men by the Japanese announcer even though text says Min Min in the Japanese trailer as well. It may be the actual pronunciation, as Min Min herself says her own name "Men Men" when chosen.
  • Nice Hat: Min Min wears one that resembles a ramen bowl.
  • Our Dragons Are Different: Twice over. Not only does she have dragon-themed ARMS that fire lasers, but she can overcharge her left arm into a dragon that permanently charges and enlarges its equipped ARM until she takes a huge hit, regardless of which ARM is equipped to it.
  • Palette Swap: Min Min's dragon arm will change colors along with her clothes.
  • Perpetual Frowner: Always has either a determined scowl or an ambivalent grimace, even in her victory animations. The only few times we see her smiling is a nervous smile in one of her character arts where she's surrounded by younger fans, and a particularly big smile in another one after winning the Party Crash Bash. In another art, while the other girls seem excited at the presence of Lola Pop, she's scowling. However she's seen smiling in both her trailer and her official render for Super Smash Bros. Ultimate.
  • Playing with Fire: Her Dragon and Ramram ARMS are capable of burning opponents.
  • Punny Name: The bearer of the Ramram ARMS is named Min Min.
  • Repetitive Name: Min Min. Also her chakram ARMS Ramram.
  • The Resenter: Is said to be somewhat jealous of Ribbon Girl becoming successful in such a short amount of time.
  • Shock and Awe: Accompanying Min Min's signature Dragon ARM on official art is the "Shock" attributed Megawatt.
  • Shout-Out: The name of her family's noodle place is Mintendo Noodle House, playing on her own name and her creator's name. Similarly, its Japanese name (麺天飯食堂, or "heavenly noodle eatery") is a play on the kanji for Nintendo (任天堂, which is generally interpreted as "leave luck to heaven").
  • Spike Balls of Doom: Downplayed; like Master Mummy's Megatons, her Megawatts have blunted spikes all over them.
  • Stealth Pun: Her name is derived from the word, "ramen," given that her arms are literally made of ramen noodles.
  • Tights Under Shorts: She wears a pair black capris under her shorts.
  • Trademark Favorite Food: Appropriately, her favorite food is her mother's ramen. This goes to the point where one of her victory phrases is "I like ramen" in Chinese.
  • Weight Woe: Though her English bio lists her weight as "unimportant", in Japanese she's said to be dieting.
  • You Gotta Have Blue Hair: Min Min has green eyebrows hidden under her ramen hair. This can be seen more clearly in certain close-up shots, most notably her victory pose showing off her dragon ARM.


The Scrapyard Scrapper
Voiced by: Ayumi Fujimura

A teenage girl not born with the power of ARMS but pilots a Mini-Mecha in battle to keep up. The mech allows her to armor through weaker attacks much like Master Mummy and her unique trait is the mech's jetpack, which gives her more agility for dashing and hovering in the air.

  • Ascended Fangirl: She's a fan of her fellow boxers who now gets the chance to fight against them.
  • Badass Normal: She's the only member of the cast who lacks the Arms ability. She uses a robot as a substitute. Along with the artificial fighters Helix and Byte & Barq, she is classified as a "second generation" fighter.
  • Bookworm: She really enjoys reading, and sometimes uses her mech as a portable library.
  • Brainy Brunette: Her profile mentions she's fifteen, which currently makes her the youngest human member of the cast. Despite this, she's able to competently pilot a flying mecha and operate its weapons in the heat of battle.
  • Color-Coded Characters: Yellow.
  • Expy: A teenage mechanical genius who fights among superhumans in a self-designed Mini-Mecha equipped with hoverjets and assorted weapons immediately brings to mind both D.Va and Tron Bonne.
  • Drop the Hammer: Her secondary Whammer ARMS take the shape of a hammer and come with the Stun element.
  • Fangirl: According to her profile, she's a big fan of the other ARMS fighters, especially Ribbon Girl. She also seems to be a fan of Max Brass, considering she "grew up watching him dominate the ARMS League" and even met him in person when she was younger.
  • Fingerless Gloves: Wears these on her real hands.
  • Future Spandex: Out of practicality, she wears one inside her Mini Mecha.
  • Gatling Good: Her primary Revolver ARMS act as a slow-firing rotary gun.
  • Genius Sweet Tooth: Implied by Biff when she goes up against Lola Pop.
  • Home Stage: Scrapyard is her home arena.
  • Homing Projectile: Her tertiary Homie ARMS take the form of missiles that lack manual control but home in greatly on the opponent.
  • Idiot Hair: Despite being a Brainy Brunette.
  • Immune to Flinching: Justified; since she pilots a mecha, weaker attacks won't make her flinch. In one of his explanations of the fighters Biff refers to her as "The Rocket Girl Who Never Flinches".
  • Instant Awesome: Just Add Mecha!: Mechanica fights by piloting a Mini-Mecha.
  • Leitmotif: Mechanica gets a spacey techno song, with what sounds like a distorted version of her voice in parts.
  • Little Miss Badass: Little? Check. Miss? Check. Badass? Check!
  • Nonstandard Character Design: The only human fighter without ARMS, and as a result, she also lacks the neon colored eyes with swirl patterns in the pupils that the other human fighters possess.
  • Sci-Fi Bob Haircut: Has her hair in a bob and has a science theme.
  • Shock and Awe: Her Revolver ARMS have the Electric element.
  • Shorter Means Smarter: Outside her mecha, Mechanica is at least 5'1" according to her bio. This makes her the smallest of the human fighters.
  • The Smart Guy: Too weak to fight on her own, but smart enough to make a mech suit to do it for her. In the 5/17 Direct Biff mentions that she must be a genius. Confirmed for certain thanks to how one of the highest stats on her profile's graph is IQ.
  • Smart People Wear Glasses: Or goggles, in her case.
  • Stuff Blowing Up: Her tertiary Homie ARMS have the Explosion element.
  • The Team Normal: Unlike the other human fighters, she was not Randomly Gifted with ARMS powers. Instead, she's just a regular girl fighting in a robotic suit she built herself, that has similar capabilities to ARMS.
  • Teens Are Short: Is fifteen and 5'1" when outside her suit.
  • Teen Genius: Considering her very high IQ, that she designed, built and maintains her Mini-Mecha herself, and pilots it in direct combat at the age of just fifteen? This goes without saying! According to the gallery, she's even hired to repair the other fighters' ARMS weapons.
  • Wrench Wench: She built the mech unit she uses herself and knows how to operate it.

The Silver Screen Queen
Voiced by: Adeyto

A famous movie star whose ARMS are in her hair (leaving her with regular arms where they should be). Her unique trait is her Actress Aura, which can slow down time to allow her to dodge punches, float, and charge her attacks even in midair.

    Byte and Barq
The Clockwork Cops

A tag team of fighters consisting of a clockwork robotic cop and his similarly mechanized canine companion. Their unique trait is that they fight as a team, with Barq being an AI-controlled assist. Barq attacks on his own and can take hits for Byte, and Byte can use Barq as a springboard to parry punches and get a high jump.

  • Assist Character: Barq isn't directly controlled by the player, but he's useful in keeping up the pressure on the opponent.
  • Big Friendly Dog: Barq might be all head but he still is rather large and gets along well with Byte.
  • Blue Is Heroic: They work for the police and wear a shiny, official-looking blue.
  • Canine Companion: Barq helps out Byte by acting as a footstool/springboard and getting in extra attacks.
  • Color-Coded Characters: Metallic blue and gold
  • Combining Mecha: When they hit their Limit Break, they combine into one robot. They actually abused this feature to get into the ARMS Grand Prix in the first place by signing up while combined.
  • Clockwork Creature: Were introduced as the "Clockwork Cops" and have visible Windup Keys.
  • Cool Shades: Barq wears a pair of sunglasses.
  • Double Meaning: One of their win quotes has Byte call the team the "long arms of the law".
    • The Long Arm of the Law is also what they are referred to as in the German and Dutch versions of the game instead of the Clockwork Cops.
  • Equippable Ally: Barq can double as Byte's head.
  • Face of the Band: invoked Barq appears to be this for the duo. Fans of them wear helmets like Barq's rather than hats like Byte's.
  • Fusion Dance: Barq has the ability to become Byte's head in order to perform an attack together.
  • Hand Wave: Biff comments that the sea breeze is what keeps the duo's keys wound up and their gears constantly moving.
  • Heroes Love Dogs: Byte is a cop who seems to appreciate his robot dog's work.
  • Heroic Dog: Barq is a police dog so it's only natural.
  • Home Stage: Buster Beach is their home arena.
  • Homing Projectile: Like Mechanica's Homie, Byte's primary Seekie ARMS take the form of missiles with no manual control but high homing properties.
  • Leitmotif: A tropical conga beat with steel drums for the beach police.
  • Loophole Abuse: Despite being a pair (and thus, normally illegal), they were allowed into the ARMS Grand Prix by signing up while combined. Even after the fact that they were two robots was public knowledge, their popularity even with Max Brass kept them from getting disqualified.
  • Mechanically Unusual Fighter: The other fighters fight solo. Byte fights with Barq as an Assist Character.
  • Machine Monotone: Byte speaks this way. Averted with Barq, who sounds like an organic dog.
  • Nice Hat: Byte wears a custodian helmet to show off his police nature.
  • Non-Elemental: His Bubbs have no element, but can enlarge when charged for more damage.
  • Noodle Incident: Kid Cobra has had a run-in with Byte & Barq, according to Biff. No explanation about what happened, whether it was a chance encounter or if Kid Cobra was breaking rules.
  • Not So Above It All: Even though Byte and Barq are law-enforcement robots, they technically cheated to get into the ARMS Grand Prix.
  • Not the Fall That Kills You…: Byte's grab attack damages opponents when they're knocked to the ground, since he launches them after grabbing them instead of hitting them.
  • No Waterproofing in the Future: Their bio mentions one of their hobbies is avoiding salt water, and their weakest stat is "water resistance". You'd think they wouldn't have been assigned to beach patrol. Coyle's notes on the duo have her suggest she could give them waterproof bodies but she probably won't.
  • Playing with Fire: Byte's secondary Cracker ARMS have the Fire element. Additionally, Barq is equipped with one of Spring Man's Toasters in his mouth.
  • Power Fist: Similar to Ninjara's Buffs, his tertiary Bubb ARMS are basic gloves with no element.
  • Punny Name: This works two ways.
    • One being the classic phrase of "Their bark is worse than their bite."
    • The other doubles as a Meaningful Name for Byte due to his robotic nature.
  • Ridiculously Human Robots: Byte, though less in terms of appearance and more in the way he moves and acts.
  • Robot Athlete: Both of them are robot boxers.
  • Robot Buddy: Barq is this to Byte even if they are both robots. Basically a robot buddy with a robot buddy.
  • Robot Dog: Barq is a robotic police dog head.
  • Shock and Awe: Byte's primary Seekie ARMS carry the Electric element. Uniquely, it seems to have the Explosion element secondarily, as unlike other Electric ARMS, the Seekies explode on contact.
  • Token Non-Human: Shares this role with Helix due to the fact they are robotic police.
  • Undying Loyalty: Implied. If Byte is being controlled by Hedlok, Barq won't be there to help the skeletal menace.
  • Visual Pun: Byte has a literal handlebar mustache.
  • Video Game Cruelty Potential: As PBG puts it, "in order to win you have to punch the dog in the face and that makes me really sad".
  • Waddling Head: Or Wheeling Head in this case, since Barq is just a robotic dog head on a single rolling wheel.
  • Windup Key: The duo has these due to being cops based on clockwork-styled robotics. Byte's are more noticeable as they appear on his shoulders while Barq has a single one on his back that might as well be his equivalent of a tail.
  • Xtreme Kool Letterz:
    • Byte's name is Justified since a byte is a real unit of digital information, something a robot like Byte would use frequently.
    • Barq's name is just "Bark" with a "q."

    Kid Cobra
The Speed Demon
Voiced by: Ryouta Takeuchi

A professional snakeboarder who fights with snake ARMS and his motivation is to increase views for his livestreams. His unique trait is both his ground and air dash go faster and further while his arms are charged. Also when charged, his forward dash allows him to duck under punches.

  • Ambiguously Human: He's odd-eyed, his face is hidden under a helmet/mask, he was born with the ARMS ability, and the shape of his body is a bit too snakelike even for someone who calls himself "Cobra". In the end it is likely to just be part of his persona as a famous snakeboarder.
  • An Ice Person: His Coolerang ARMS, if the name didn't give it away.
  • Animal Motifs: If his name and hobby did not tip you off it is obviously snakes, particularly cobras. When viewed from behind the cobra shape can be seen from his helmet which extends down to the shirt graphic. Not to mention despite their name being inspired by salamanders, the set of ARMS he has mainly been viewed to have on combined with his movements do look rather snakey (Complete with scales when viewed up close similar to when Min Min's dragon is active).
  • Battle Boomerang: His tertiary Coolerang ARMS.
  • Blow You Away: His signature Slamamander Arms produce wind and tornadoes during Rush.
  • Calvinball: The Snakeboard sport he does.
  • Chick Magnet: He's got a lot of female fans, as seen in his ending.
  • Color-Coded Characters: A rather poisonous purple with a touch of bright green.
  • Cool Helmet: He wears a white helmet-mask combination that's shaped like a cobra.
  • Evil Sounds Deep: As mentioned below he probably is not necessarily evil, but the way he slowly says "Cobra..." at the end of his trailer does have a sinister element to it.
  • The Faceless: His face is hidden under a Cool Mask that doubles as his names(n)ake.
  • Flash Step: Kid Cobra's unique ability is to sacrifice his charged punches to dash twice whether on the ground or in the air, effectively giving him the fastest dash in the game. Without it, he otherwise has the slowest dash in the game.
  • Fragile Speedster: Because of his ability to dash up to five times, he's effectively the fastest character in the cast. However, this ability requires him to sacrifice the raw power and elemental effects that would come with his charged punches.
  • Fashion Dissonance: His outfit kind of gives the desire to shout "The 1990s called, they want their clothes back."
  • Good Colors, Evil Colors: Wears purple and green in contrast to the more heroic characters. Leans more towards Heel than an actual bad guy though.
  • Home Stage: Snake Park is his home arena.
  • Instant Web Hit: What he must expect from his fights due to the fact he's livestreaming them.
  • Lean and Mean: The build of his body is a bit on the skinny side making him almost look like a snake with legs.
  • Leitmotif: A fast-paced rock mix of the main ARMS theme which perfectly catches the feeling of extreme sports.
  • Mismatched Eyes: His right eye's green, his left purple.
  • Noodle Incident: Kid Cobra has had a run-in with Byte & Barq, according to Biff. No explanation about what happened, whether it was a chance encounter or if Kid Cobra was breaking rules.
  • Playing with Fire: The Hydra ARMS are fire-attributed.
  • Spread Shot: His secondary Hydra ARMS, like Spring Man's Tribolts, are a multi-shot weapon, but fire vertically instead of horizontally.
  • Totally Radical: He's a snaker (skater) dude.
  • Whip It Good: His primary Slamamander ARMS acts a whip similar to Ribbon Girl's Slapamander, but with the wind element.
  • Why Did It Have To Be Mongoose?: It is implied on Springtron's Grand Prix battle against Kid Cobra that the ladder is afraid of mongoose, which fits the King Cobra motif very well.

The "Man" of Mystery

A green blob creature with ARMS designed after DNA double helices who was accidentally created by scientists researching the ARMS phenomena. His unique trait is his unusual body, which allows him to move in weird ways for added defense and to confuse the opponent.

  • Abusive Parents: Dr. Coyle was the head of the scientists who created Helix and according to her journal when Biff read it, sees him as kind of a disappointment. Biff in return tells the blob not to worry about it and instead see making your parents ashamed of you as a rite of passage.
  • An Ice Person: His secondary ARMS are the self-explanatory Ice Dragons.
  • The Baby of the Bunch: Can possibly be interpreted this way due to only being two years old- combined with juvenile-sounding voices. Then again, he is a scientific creation so it probably does not matter.
  • Blob Monster: He's made of a green substance that can stretch and collapse into liquid.
  • Color-Coded Characters: A slightly translucent deep green.
  • Confusion Fu: His ability to contort his body and move in strange ways is his main mechanic in order to frustrate his opponents.
  • Covered in Gunge: His signature Blorbs splatter his opponents with blue slime on contact, obstructing their vision.
  • Difficult, but Awesome: His below mentioned mechanical quirks gives playing him a bit of a learning curve, reducing his potential tier ranking, but still leave him formidable
  • Dub Name Change: In Japan, he's known as "DNA Man".
  • Eye Scream: Averted with his blinding Blorb ARMS. Biff says they're pretty sure the goo from them is non-toxic.
  • Fighting Clown: Silly and unorthodox movements and sounds, but no less effective for it.
  • Home Stage: DNA Lab is his home arena.
  • Interface Screw: His default ARMS, Blorb, are the first ones with the Blind element. If a charged Blorb hits an opponent, their view is blocked by blue goo, similar to a Blooper in Mario Kart.
  • Leitmotif: A bizarre techno remix of the main ARMS theme, fitting the man(?) made for ARMS fighting.
  • Luckily, My Shield Will Protect Me: His tertiary Guardian ARMS, which expand out into electrical shields to deflect attacks.
  • Mechanically Unusual Fighter: Helix's scientific nature allows him to stretch and move to inhuman lengths and shapes. His dash and jump respectively double as a squash and stretch to duck under or flex above attacks. His ARMS weapons have slightly unusual timing; the Guardian is a shield that can block a few hits as it drifts towards the opponent that needs to be pumped a second time to speed up after closing the gap. His Ice Dragon has the typical delay between punch and firing and the Blorb bounces on the way towards the opponent.
  • Nightmare Fuel Station Attendant: The most unnatural looking and sounding character in the entire cast, but at the same time he's amusing and childish.
  • One-Way Visor: He wears one that doubles as his "eyes".
  • Our Dragons Are Different: Similar to Min Min, one of Helix's main ARMS choices are dragon heads. A major difference is that his dragons specialize in blasting ice breath.
  • Palette Swap: The enemies in "1-On-100" mode seem to be black, possibly non-sentient versions of Helix, probably created by the same scientists who made him.
  • People Jars: One piece of his official artwork shows him breaking out of one, and the stage his trailer introduces him in is full of them.
  • Plucky Comic Relief: His bizarre design, and equally bizarre movements, make him serve this role on the roster.
  • Precocious Crush: Their pre-fight line indicates the two year old Helix has a crush on Twintelle.
  • Readings Are Off the Scale: His bio on the official website has a joke "Grossness" stat that not only extends off the chart, but also off the edge of the screen (It even wiggles).
  • Rubber Man: According to his bio, Helix can stretch anywhere from between thirty to two hundred and fifty centimeters (Approximately 0'10"-8'2").
  • Shock and Awe: His Guardians have the Electric attribute, and shock any opponent that they touch.
  • The Unfavorite: Coyle's first work, but despite that connection, her journal dismissing him as flawed seems to indicate there's no love lost for poor Helix.
  • Technicolor Science: He is a creation by ARMS Laboratories and his palette is a slimy green with pink and blue highlights.
  • Token Non-Human: Shares this role with Barq and Byte, being one of the only current fighters that do not consist of flesh and blood (or implied formerly, in the case of Master Mummy). He is instead a substance that is reminiscent to Flubber.
  • "Well Done, Son!" Guy: According to his bio Helix's reason for fighting in the ARMS tournament is to prove the merit of the ARMS Laboratory's work. Dr. Coyle, who was the head of scientists who created him to begin with is also in the competition.

Update Fighters

    Max Brass
The Commish
Voiced by: Dominic Allen

The head of the ARMS league, and the Champion of the Grand Prix. Fitting his status, his ARMS look like belts. Originally the Final Boss of Grand Prix mode, he is the first post-release fighter introduced to the game, made playable in the first update. His unique trait is that charging his ARMS or completing a throw will buff his body mass to give him armor from weak attacks. Like Spring Man, he can charge to repel punches and his ARMS stay permanently charged at critical health and he will also stay buffed.

  • Big Good: He's not just the Champion, he's actually the head of the ARMS league, and the guy who made the tournament in the first place!
    • He also appears to allow non-ARMS users to enter the ARMS league such as Mechanica, as well as robots and experimental fighters. As long as they can provide a fair and thrilling match he doesn't seem to care who enters.
  • Color-Coded Characters: Light metallic teal with brown/gold and red accents.
  • Cool Helmet: Shiny gold with a mohawk/pompador on top.
  • Cool Old Guy: He's the only middle-aged fighter in the game at 52 years old, but the fans love him for his hamminess and influence in the ARMS world, and he encourages anyone to show him their all.
  • Difficult, but Awesome: Max Brass has a great set of abilities and useful starting ARMS, but unlike all other fighters, his punches have zero guidance behind them, meaning if curved the wrong way, your punch will miss the enemy by a mile. Using Max Brass effectively requires you to have complete control over where you're sending your punches so you don't constantly whiff, but having such control gives you a juggernaut with a Fire-Explosive combo of elements and the ability to laugh at weaker hits. In other words, to effectively use the champ, you'll need to play like a champ.
  • Drop the Hammer: His Kablammer ARMS are giant, explosive mallet-like weapons.
  • Domino Mask: Built into his helmet, no less.
  • Eagleland: A minor example is in his introduction trailer as he is presented through the use of red, white, and blue rings.
  • Final Boss: Of the Grand Prix mode on level 3 and lower difficulty.
  • Graceful Loser: He's seen clapping for Spring Man in the latter's ending image, smiling at the new Champion.
  • Having a Blast: His signature Nade and Kablammer ARMS explode upon impact. The Nade even resembles a grenade.
  • Hell-Bent for Leather: His belt ARMS look like they're made out of leather.
  • Hoist by His Own Petard: Max's Brass critical permacharge means that his two signature Explosion-type ARMS make him a bigger target. Fortunately, his buffed state means he takes half damage from it as well as not flinching.
  • Home Stage: Sky Arena is his home arena.
  • Hot Paint Job: Has a flame motif on his boots and outfit.
  • Irisless Eye Mask Of Mystery: His mask makes his eyes look like this rather than show off the swirly Exotic Eye Designs other fighters with ARMS have.
  • Large and in Charge: At 6'4" he's the the second tallest fighter at a consistent height (Master Mummy is first at 7'6"), and he's both the reigning Champ and the head of the sport outright.
  • Large Ham: This guy's every bit as boisterous as he is big. He's also the only character (besides Hedlok) that laughs as he's being introduced by the announcer in Grand Prix.
  • Leitmotif: The theme for his stage, the Sky Arena, is a dramatic orchestra rock song with chanting in the background; it's a climactic song fitting for the head of the ARMS League.
  • Masked Luchador: Given the belt, flame motifs on his clothes, mask, and Mayincatec design of his stage (from what we can see), he may be based off this.
  • Mirror Boss: If you play as Max Brass in Grand Prix, the final boss is... another Max Brass, with a different color scheme. Biff lampshades this, as shown under Tomato Surprise.
  • Multi-Armed and Dangerous: When Hedlok steals his body for the True Final Boss.
  • Nigh-Invulnerability: When he reaches critical health, he buffs up and becomes an absolute damage sponge, not just taking less damage, but no-selling every attack save for grabs you throw at him. That said, he loses the bulk temporarily if he takes a hit from ARMS with Electric or Ice attributes, but it comes back after the effect wears off, so you'd best make it count if you land one.
  • Older Than They Look: The guy's actually 52 years old, but between his appearance, voice, skill, and enthusiasm, you'd be forgiven for thinking he was in his 30s or even late 20s.
  • Pec Flex: Makes this in one of his victory poses, alongside a few other poses.
  • Picky Eater: If you have Springtron pit against Max Brass in Grand Prix mode (Which is the finale), according to Biff, the latter is a picky eater. Apparently his weakness is bell peppers.
  • Playing with Fire: His signature Roaster arms are similar to Spring Man's Toaster arms, only with higher damage output at the cost of the guidance system, and also purple fire.
  • Power Fist: His primary Roaster ARMS are a boxing-glove like weapon. The Nades also count, with the knuckles resembling the pineapple-like shell of a grenade.
  • Promoted to Playable: He's the Final Boss of Grand Prix, and the first post-release character.
  • Red Baron: His title is "The Commish", as in the Commissioner of the entire ARMS League.
  • Smug Super: For as nice of a guy as he is, he does have a big ego that is entirely justified by his power and skill.
    "Who's the champ? Me!"
    "I'm the best!!"
  • Spirited Competitor: He's not some corrupt champion trying to cling to his belt, he just wants to set up a great tourney and put his title up there for the winning.
  • Superheroes Wear Tights: He's wearing a spandex suit that looks like either a superhero or a luchador outfit.
  • Technicolor Fire: The fires of his Roaster gloves are purple.
  • Temporary Bulk Change: He can increase the size of his muscles for a brief period of time to prevent flinching.
  • Tomato Surprise: Subverted. During his final Grand Prix battle, he faces another Max Brass, and Biff believes that the Max Brass you're playing as is an imposter. However, defeat the other Max Brass (and Hedlok if your difficulty is high enough), and Biff will remark during the victory ceremony that he "always knew you were the real deal", implying the one you fought (and saved) was the real imposter.
  • Too Many Belts: Not in his design, but his Arms are belts and his arena is themed around the championship belt.
    • This is taken to another level in his ending visual as it involves him admiring all the belts he's won in the past framed up on a wall as his newest part to the collection lays on a desk likely to soon get the same treatment.
  • We Used to Be Friends: With Dr. Coyle, as her ending screen is a picture of them seemingly as friends. It's been torn in two, yet taped back together.
  • World's Strongest Man: You don't become the absolute, uncontested peak in the world where twenty percent of the population consists of extendo-arm superhumans without being this.

    Lola Pop
The Sucker Puncher
Voiced by: Soness Stevens

A traveling fighting clown with gummy candy ARMS introduced in the third update of the game. Lola Pop has traveled the world doing street performances and hopes to one day open a circus of her own. Her unique trait is the ability to quickly inflate her whole body; which allows her to move while blocking, bounce on the ground and air-block.

  • Acrofatic: In her inflated blocking form, she's agile enough to not only move, but bounce and flip through the air unpredictably.
  • Alien Hair: As with other female characters with the ARMS power. Her hair is made of hard candy and the bun on her head has the shape of a lollipop.
  • Art Attacker: One of Lola's default ARMS, the Biffler, covers the screen with stamps of Biff's face to temporarily hide her opponent's view.
  • Attack Reflector: The Clapback ARMS, part of Lola's default selection, reflect enemy punches back at them when charged, making them a great defensive option.
  • Badass Adorable: No doubt the cutest clown you'd ever meet. Just don't underestimate her. One wrong move in a match and this cutie will send you flying.
  • Cloudcuckoolander: Some of her mannerisms and movement patterns are pretty wacky.
  • Color-Coded Characters: Orange and teal.
  • Confusion Fu: One of the key aspects to Lola's fighting style is her unpredictability; having plenty of unusual movement patterns and a selection of ARMS that have all sorts of wacky effects to keep opponents guessing.
  • Earn Your Happy Ending: After many years as a Street Performer and dreaming of starting one, she uses the money and press from winning the Grand Prix to open up the circus of her dreams.
  • Expy: Her clownish demeanor (complete with red nose), extendable ARMS and ability to inflate herself just like a balloon makes her highly reminiscent of Lanky Kong.
  • Fashionable Asymmetry: Subtly so. Half of her baggy pants are striped and the other half polka dotted. The pattern changes based on her Palette Swaps, but they're always asymmetrical.
  • Fighting Clown: Literally. If the red nose, puffy pants, and fact you can play as her in a fighting game did not tip you off she is definitely one of these. Furthermore, she isn't meant to be a Joke Character.
  • Fighting with Chucks: One of her default arms are called the Funchuks. They work by having her swinging around a large pair of nunchakus that can also stun opponents.
  • Genki Girl: Befitting for a lady who happens to be a colourful Non-Ironic Clown, she has a very sweet, energetic personality, and clearly enjoys putting on a show as she battles.
  • Home Stage: Via Dolce is her home arena.
  • Inflating Body Gag: Her way of blocking and parrying attacks is by inflating her whole body.
  • Interface Screw: Her Biffler ARMS resembles Kid Cobra's Hydra, but with blue stamps depicting Biff's face on them in place of rockets. When the opponent is hit by one of the stamps when charged, their screen is stamped, obstructing their view.
  • Leitmotif: Her home stage, Via Dolce, has an upbeat song featuring traditional European renaissance instruments such as violin, guitar, and accordion with a strong rhythm section.
  • Non-Ironic Clown: For the most part, she looks and behaves the way one can expect of a silly clown.
  • Punny Name: If "Lola Pop" isn't just a stage name, then it's rather fitting that a silly lady with candy ARMS would have a name that sounds like "lollipop".
  • Sweet Tooth: As expected for someone with hard candy and lollipops for her hair and colourful gummy candies for her ARMS, one of her hobbies is eating candy. As seen in her gallery pictures, Lola is also very skilled at making patisserie sweets.
  • Temporary Bulk Change: Her main ability is puffing up her whole body to block attacks.
  • Woman of a Thousand Voices: As seen in several of Lola's victory poses, she's surprisingly good at doing convincing animal impressions.

The Spirited Fighter
Voiced by: Toru Sakurai

A proud, spiritual warrior with woven bracelet ARMS introduced in the fourth update. Misango is devoted to defending his homeland and people, the Misangans. He enters the ARMS tournament in order to prove that the Misangan fighting technique is superior above all others. His unique trait is that he fights with a "mysterious entity" mask that can imbue him with randomly generated buffs as well as shield him during a charge.

The Mean Machine
Voiced by: Peter Von Gomm

A strange robotic fighter resembling Spring Man. He shows up to challenge you in Grand Prix if you're doing TOO well. Originally an NPC Bonus Boss, he became playable with the fourth update. His unique trait is that charging his ARMS will release a energy pulse that disables any ARMS that comes in contact with it. Like Spring Man, he can also parry punches after charging but unlike Spring Man, he doesn't stay charged at low health.

  • The Baby of the Bunch: Similar to fellow ARMS Laboratory creation, the two-year-old blob creature known as Helix, this robot is the youngest fighter in the league at zero. It might not truly matter though as he is a creation of metal made in the likeness of another battler.
  • Bonus Boss: Added in the 3.2 update to challenge the player right before Max Brass if they've had a perfect run so far.
  • Chest Insignia: Doesn't use Spring Man's symbol, instead having one that resembles a "T".
  • Do Well, But Not Perfect: He shows up to challenge you if you get to Max Brass without losing a single round on Difficulties 4 or higher, so those that wish to avoid him must follow this trope.
  • EMP: Every so often, or, when playable, once his ARMS are fully charged, he sends out a pulse which disables your ARMS. The only way to avoid it is to get out of its range.
  • Evil Knockoff: Of Spring Man. It's not known if he's actually evil, but he is very aggressive and interrupts your Grand Prix challenges.
  • Evil Counterpart: To Helix, although downplayed in that Springtron hasn't proven itself to be anything more than a delinquent.
  • From Bad to Worse: There's a very good chance you'll encounter a double Springtron in Co-Op mode if you do well enough.
  • Home Stage: Sparring Ring is his home arena.
  • Jerk with a Heart of Gold: He's the intimidating mascot of an incredibly dubious corporation; despite this, his Grand Prix ending shows him having a touching moment with a young fan.
  • Moveset Clone: Of Spring Man, down to having the same starting ARMS and abilities. He even gains the ARMS Spring Man gains from the ARM getter minigame.
  • NameTron: Spring Man with "Tron" instead of man.
  • Robot Athlete: He's a robotic duplicate of a boxer.
  • Robot Me: He's a robotic duplicate of Spring Man created to advertise ARMS labs and discover the other fighters' weaknesses.
    • Apparently his creator sees him as superior to the fighter he was based on:
    Dr. Coyle: "Yes... better than the original."
  • Smug Super: His hobby is "flawless victories".
  • SNK Boss: As to be expected of a Bonus Boss in a fighting game. He's slow and weak under normal circumstances but his signature ability is a shockwave that, in order, disables your arms, charges his arms, and makes him really fast. Good Luck.
  • Token Non-Human: Shares this quality with Helix, Byte, and Barq. He's also something of a combination of the three as he's a robot and a creation of ARMS Laboratories.

    Dr. Coyle
The Rad Scientist
Voiced by: Donna Burke

A brilliant scientist who's the head of ARMS Laboratories. She's obsessed with ARMS research and Springtron, Hedlok, and Helix are the results of her experiments. She has even experimented on herself, which gave her a set of ARMS of her own in the form of Tesla coils. Dr. Coyle was hinted at in the game previously and made her debut for the fifth update of the game. Her unique traits are that she can turn invisible during a block, levitate and air-guard, and gain a third ARM when charging her punches.

  • Ambition Is Evil: Her aim is to be the peak, both the Head of ARMS Labs and the Champion of the ARMS League, putting her at the fore of both sides of the old ministry — and she doesn't care what she has to do to get herself there.
  • Awesome Aussie: Though subtle at times, she does have a mild Australian accent and she is pretty smart. What hinders her however is her obvious villainy. To be fair however Mr. Yabuki stated everyone's a protagonist, making her technically a Villain Protagonist.
  • Combat Stilettos: Wears high-heeled boots with spikes on the soles near the toes. Unlike Ribbon Girl and Twintelle, their lack of any impracticality is justified because Coyle never actually touches the ground.
  • The Computer Is a Cheating Bastard: In the Grand Prix boss fight, Coyle gets a fourth ARM when charging up, in addition to the third. She also does 200 grab damage as opposed to her 150 baseline.
  • Curtains Match the Windows: Has green hair and eyes.
  • Deadpan Snarker: Her win quotes against some of the fighters can come off as rather sarcastic and sometimes savage, yet cheesy. The most notable examples include:
    • Spring Man: Spring's over!
    • Ribbon Girl: Now that's a [stressing the I to sound musical] hiiiiiiit!
    • Ninjara: Sayonara, Ninjara!
    • Master Mummy: Go back to sleep.
    • Min Min: Ramen ARMS, really?
    • Twintelle: Time for a haircut!
    • Byte and Barq: All bark, no bite.
    • Lola Pop: Clowns don't scare me!
    • Helix: Aww, that's my baby.
    • Springtron: Yeah, better than the original.
    • Max Brass: Who's number one now?!
  • Empowered Badass Normal: Coyle's not a natural ARMS wielder, having been well into adulthood without ever gaining what is defined as a puberty-acquired power — however, through sheer determined study and continuous self-experimentation, she gave herself ARMS powerful enough to send Max Brass skyward and out of his own arena. For good measure, when Hedlok fails to secure victory even with her power, she demolishes it with virtually no effort,
  • Evil Genius: Like Mechanica, one of her stats is a high IQ.
  • Evil Is Hammy: Not that it matters much, since she's living in a World of Ham.
  • Fighting with Chucks: One of her default ARMS are ice type nunchuks.
  • Foil: To Mechanica, as instead of making an external suit, she experimented on herself, and instead of being a fan of Ribbon Girl and Max Brass, Coyle is a fan only to herself.
  • Foreshadowing: A "Doctor C." was referred to on the ARMS Twitter every so often. She was also foreshadowed in Springtron's ending, wherein her hand was seen holding his victory photo.
  • Genius Bruiser: Coyle's as smart as they come and, by her own designs, as strong as they get.
  • The Glasses Gotta Go: Her ending visual shows her wearing a pair of circular-framed glasses.
  • Godzilla Threshold: After being bested in the Grand Prix, she calls down Hedlok to take her body for a chance at the victory.
  • Greater-Scope Villain: The creator of Hedlok and the first openly villainous fighter, she outright usurps Max Brass's position as the final boss in Grand Prix mode at Level 6 or 7. Hedlok will still jack her body for the final fight (though it's heavily implied that not only does she deliberately summon him, she's at least partially in control), but if he loses, Dr. Coyle will outright destroy him, cementing her as the bigger threat.
  • Green and Mean: One of her main colors is green and she is Obviously Evil complete with skulls as her icon.
  • Green-Eyed Monster: She tries to pass it off as mere scientific interest when discussing Twintelle but isn't fooling anyone. She drops the pretense when talking to Misango, whose even more versatile than she is.
  • Home Field Advantage: Thanks to her passive hovering, she is immune to the conveyor belt in [NAME REDACTED], making it easier for her to handle the stage's layout.
  • Home Stage: [NAME REDACTED] is her home arena.
  • I Lied: The ARMS Lab research notes of Hedlok's development states that, after it escaped, they went to Dr. Coyle for aid in subjugating it, but she had "lost interest". This was all a ruse, as she had much bigger aspirations for the experiment gone rogue.
  • "It" Is Dehumanizing: Coyle seems unable to view her fighting peers are people, but as subjects to subjugate for the sake of her growing power, or to experiment on at her leisure. As Biff reveals she's been behind the Party Crashes among the other disrupting events, the Freudian Slip calling the Party Crash an "experiment" and the fighters her "test subjects" before awkward corrections are solidly her own.
  • It's All About Me: Turns out, every pursuit she's made under the ARMS Research Labs was in the goal to make herself the most powerful ARMS wielder of all.
  • Invisibility: She can turn invisible to her opponent when blocking, as well as standing up after getting knocked down.
  • Jet Pack: Her weapon acts as one, making it so she constantly floats during the battle. Granted, it seems to use air, gravity or something else less visible than jets.
  • Kubrick Stare: It seems to be habit to glare at her opponent from beneath her eyebrows.
  • Large Ham: Some of her lines and actions can come off as overly dramatic.
  • Leitmotif: Ominous electronic rock with orchestral elements and a One-Woman Wail added, which sounds like a twisted version of Max Brass' theme. It also notably includes the melody and other elements of Hedlok's theme, cementing that he is her creation.
  • Mad Scientist: Her main motif.
  • Meaningful Name: The woman with Tesla coils for ARMS is named "Coyle."
  • Mechanically Unusual Fighter
    • The device on her back makes it so that she doesn't touch the ground. As such, she doesn't jump. Instead, pressing the jump button will make her float up to the normal jump height and just... stay there. As long as you're holding the jump button. She can still dash, block, punch, and everything. She's just up there now. In addition, the fact that she's not touching the ground makes it so that she is unaffected by things like moving ground or springs, for better or for worse.
    • Oh, and on top of that, she drifts a bit in the direction she was moving in when you stop telling her to move. Since, you know, not touching the ground makes friction a bit harder to come by.
    • Furthermore, while most fighters with a special ability (Min Min's Dragon arm, for example) lose it on being knocked down, Dr. Coyle activates her invisibility when knocked down. This way, she can mask what she decides to do upon rising.
  • Meganekko: She is or at least used to be one according to her ending visual.
  • Morally Ambiguous Doctorate: She certainly seems smart enough to have earned a PhD, having found a way to artificially replicate the ARMS condition. It's just that what she does with her advanced knowledge is morally questionable.
  • Multi-Armed and Dangerous: She can gain a third ARM when charging left or right, and her "boss" version can gain two. Then Hedlok steals her body for the True Final Boss if playing on Level 6 or 7.
  • Noble Demon: Zigzagged. Coyle will abuse and outright skirt the League regulations liberally to usurp Max as the champion... However, she still respects that she actually has to win within the conditions of the Grand Prix to do this. Even as she flagrantly cheats, she intends to win by the letter of the law, if not the spirit.
  • No Social Skills: Where brain intelligence is her highest point emotional intelligence is noted to be her lowest.
  • Not Evil, Just Misunderstood: Her bio states her standards are not exactly nefarious, she simply just uses whatever means she can in order to become the greatest ARMS fighter. Unfortunately, while her standards aren't evil by intent, her methods absolve her of nothing.
  • Older Than They Look: At first glance would you believe she's forty-eight?
  • One World Order: The ARMS Ministry, which was a leading global power, divided into two factions upon the sport being formed: the ARMS League, which ordains combat, and ARMS Labs, which handle research and development. And Dr. Coyle, the head of ARMS Labs, is looking to consolidate both those powers for herself in becoming the champion.
  • Peek-a-Bangs: Her thumbs down-shaped hair covers her right eye.
  • Powered Armor: She fights using her wearable weapons that enable her, among other things, to fly.
  • Power Floats: Her feet pretty much never touch the ground. Advantages include immunity to things like trampolines and conveyor belts. Disadvantages include the inability to use said gimmicks for your own benefit, and not being able to dodge or charge punches via jumping.
  • Punny Name: Her name is Coyle which sounds quite similar to "coil". Her ending shows signs of her personality originally making it seem her last name is actually a Portmanteau on the word "coy" and "coil".
  • Purple Is Powerful: Has a black and dark purple mask and wears matching lipstick.
  • Promoted to Playable: After being mentioned in vagueries in game and on official social media channels she finally reveals herself as a DLC character.
  • Psychotic Smirk: When she's not grinning like a madwoman, she tends to smirk.
  • Secondary Color Nemesis: Her main motif is green, and she also has a bit of purple on her mask.
  • Slasher Smile: It's practically her catchphrase to flash a demented grin.
  • SNK Boss: Replacing Max Brass as the final opponent on Difficulty 6/7, her defensive capabilities as well as her ARMS loadout having more debilitating elemental variety (her default arms have Explosive, Electric, and Freeze effects) and the homing capability that Max Brass lacks make her even more of a challenge. Then she combines with Hedlok.
  • Sore Loser: Throws a tantrum when she loses, destroying Hedlok (with a loud "USELESS!", no less), ranting "Gah... I could've won!", and teleporting out in a huff.
  • Spikes of Villainy: Exaggerated cleats, pointy shoulder pads, her mask even has spiky "eyelashes".
  • Statuesque Stunner: At 5'9" she is an inch behind Twintelle from being the tallest female fighter but the spikes on her boots might be playing a big part in this.
  • Totally Radical: Her official title is "The Rad Scientist".
  • True Final Boss: Based on the update notes, she will appear at the end of the Grand Prix mode at level 6/7 when playing as someone who isn't Dr. Coyle.
  • Villainous Breakdown: See Sore Loser above.
  • Visible Invisibility: When she turns invisible, when her opponent can't see her, her outline appears for the player.
  • Weaksauce Weakness: In a sense, certain ARMS attributes function this way against her; Poison, Electric, and Freeze will prevent her from activating her invisibility on knockdown.
  • We Can Rule Together: She call's Mechanica's work amateurish, but Dr. Coyle's victory quote has her inviting the young girl to become her student.
  • We Used to Be Friends: Her ending screen is a torn in two, yet taped back together picture of her and Max Brass in happier times. Apparently he said something to her that she simply couldn't forgive, according to her pre-fight dialogue against him when playing as her in the Grand Prix.
  • With Great Power Comes Great Insanity: Coyle is said, since she was a young girl, to have been obsessed with ARMS. Then, she found out how to give herself that power. Since then, as her reveal, well, reveals, everything she's done under the umbrella of the ARMS Research Lab —from Hedlok, to Springtron, to Helix— everything was for the sake of making herself the most powerful in the world.
  • Why Did It Have to Be Snakes?: Might have a dislike to serpents given her win quote against Kid Cobra is "Snakes?!" followed by a sound of disgust. Averted with clowns however, as she tells Lola Pop that clowns don't scare her.
  • You Gotta Have Blue Hair: She has green hair that's implied to have been the result of the experiments she's performed on herself.
    • Keep that in mind, one of her alturnative colors has red hair in place of her usual green hair.
  • You Have Failed Me: When even Hedlok taking over her body can't defeat the player in Grind Prix mode at Level 6 or 7, she calls him useless and destroys him in anger.
  • Youthful Freckles: Is seen with these in her ending visual.


Voiced by: Yuu Kobayashi (Japanese)

The announcer of the ARMS League. He's usually quiet, but always game to talk about the ARMS game.

  • American Kirby Is Hardcore: In the Japanese version, he sounds like a young boy, while in the English version, he sounds like an adult announcer. However in the final game, his voice is limited to sound effects in all versions.
  • Acronym Confusion: Biff doesn't know what DNA stands for.
    Biff: "Do Not Attack?" Don't fall for it, Mechanica!
  • Ambiguously Bi: Biff has a canon Celeb Crush on Ribbon Girl, but his commentary on Max Brass' Grand Prix makes it seem like the little mascot also has a crush on him. He also describes Master Mummy's one-shoulder wrestling singlet as "sexy" in a tweet focusing on a clothing brand "Achom," which Master Mummy and Spring Man share with.
  • The Cameo: Makes an appearance in each fighter's Grand Prix ending with some being more easier to notice than others:
    • For Spring Man and Ribbon Girl he's right on stage with them, but more in the background for the latter.
    • For Ninjara he's up on the roof of the ninja's school wearing his very own Scarf of Asskicking.
    • With Master Mummy he seems to be interviewing said Grim Creeper alongside his reunited family.
    • He's one of the several backs of heads seen during Mechanica's explanation about her suit.
    • With Min Min he's eating a bowl of ramen with a group of her fans.
    • He pokes his head in the background of the dark laboratory which is Helix's home.
    • He's in a photo with Byte and Barq as well as being a grass skirt-wearing, hula-dancing bobblehead.
    • He's in the back row of Kid Cobra's group selfie.
    • He watches Twintelle's movie while staring in the player's direction.
    • His face is on Max's drink carton.
    • A balloon shaped like him is seen on the poster for the opening of Lola's circus.
    • He's simply hanging out in the shrine with Misango.
    • He's in the crowd running towards the child fan touching Springtron's hand.
    • He's in the corner watching Max and Coyle in the doctor's ending.
  • Cartoon Creature: Basically a small, yellow "person" with a fist on his head. He greatly resembles a robot of some sort.
  • Celeb Crush: Has one on Ribbon Girl.
  • Character Blog: He has a Japanese-only Twitter feed where he shares information, animations, and production art regarding the game.
  • Check, Please!: If you have Min Min in the Grand Prix, on match 9, Biff will say "Check, please!" as a reference for when customers would need a receipt.
  • Dub Name Change: Several countries have changed his name.
    • In Japan, he's known as "Cobushii".
    • In German and Dutch he is Armadeus.
    • In French he is Globule.
    • His Italian name is Armando.
    • Depending on the Spanish region he is either Manuelucho (NTSC) or Puñejandro (PAL).
  • Face on a Milk Carton: How he makes a cameo in Max's ending.
  • Fanboy: He seems to be a big fan of Ribbon Girl. When talking about her in the Directs, he calls her his idol (complete with heart eyes!) and wonders aloud if he can get her autograph. And he does!
  • Meaningful Name: His name can be seen in Western comic books as one of the many sound effects for when a fist meets a face. Likewise, his Japanese name, “Cobushii”, literally means “fist” in Japanese.
  • Mr. Exposition: It's only natural with the fact he's the announcer that he has to explain who every fighter is and their abilities.
  • Non-Dubbed Grunts: Which is pretty jarring considering how different his English voice is compared to his Japanese one.
  • Pungeon Master: Basically every line after saying which match it is will be a pun related to the character.
  • Punny Name: Some of his names mentioned above fit this style.
    • Armadeus is a combination of "Arm" and "Amadeus".
    • Manuelucho is a combination of the name "Manuel" and the word "luchar", which means to fight.
    • Puñejandro is a combination of "puñar", which means to fight and the name "Alejandro".
  • Series Mascot:
    • While Spring Man and Ribbon Girl serve this role in terms of player characters, Biff, being a smaller, cuter character, also counts as such.
    • In-universe, Biff is the mascot for the ARMS Tournaments.
  • Trademark Favorite Food: Like Min Min, he likes noodles. He's jealous that he can't have noodle arms too, to quote a line of his that was in the 5/17 Direct:
    "Oh, Ramen Gods, why must you forsake me?!"

The Secret Weapon
A floating skull-shaped robot that was originally being developed in a research facility by Dr. Coyle before running amok. It fights by latching itself onto the bodies of other fighters to battle.

He becomes semi-playable in Version 2 in the special "Hedlok Scramble" mode, where combatants fight for Hedlok's body to temporarily assume control of him.

  • A.I. Is a Crapshoot: Hedlok was originally designed to be an advanced sparring partner, but as of now, Hedlok answers to no one and will use ARMS fighters as puppets simply to beat the tar out of anyone who crosses his path.
  • Big Bad: He emerges from nowhere to steal the body of the strongest ARMS fighter in the world, Max Brass, forcing the player to save him from the machine running amok. On higher difficulties, he is instead summoned to steal Dr. Coyle's body (or be forced into symbiosis with her) in a last-ditch effort to defeat the player.
  • Blood Knight: Hedlok only seems to exist to fight, and beat up, the player, and it doesn't seem to mind this. The constant evil laughter it gives off, especially when it wins a fight, indicates that it really enjoys beating the everloving shit out of you.
  • Chest Insignia: He doesn't have a chest, but he does still have an insignia: A circle with six appendages and what appears to be this universe's version of the letter A (as in ARMS)... upside-down.
  • Damage-Sponge Boss: Hedlok Levels 6 and 7 in multiplayer have lots of health, meaning even a skilled group of players that stay alive and healthy the entire time may not be able to down Hedlok in time within the 99-second time limit.
  • Dem Bones: Hedlok's "head" is based on the design of a skull.
  • The Dragon: Turns out, he's Dr. Coyle's personal masterpiece. As Biff clues the player in during her Grand Prix mode, the "incident" at ARMS Research Lab that led to Hedlok breaking free appears to have just been her way of letting him off the leash to run amok.
  • The Dreaded: For ARMS Labs, once they realized precisely what they created all too late once it had escaped. With Dr. Coyle suddenly losing all interest, ultimately the only plan they could formulate was to let it roam and hope the League fighters could bring it down.
  • Drunk with Power: When Hedlok escaped, all that the Lab technicians could glean from its movements was that it was "in search of something". It turned out that "something" was an ideal body — in the form of the World's Strongest Man, Max Brass.
  • Evil Laugh: A metallic, hollow, raspy one. And boy, does he use it. His laugh even replaces the announcement of his own name before the battle against him in Grand Prix.
    • When attached to Dr. Coyle, her laugh is mixed in, implying that she's at least partially in control.
  • Evil Mask: Hedlok wears itself on the heads of the normal combatants. The prototype was originally planned to be worn like body armor until Dr. Coyle decided it was too difficult for ordinary humans to handle.
  • Final Boss: Along with being the True Final Boss of Grand Prix, Hedlok also serves as the 100th enemy in 1-on-100 mode, where he takes over the last Cell and fights as usual.
  • Glowing Eyes of Doom: Glowing spiraled eyes nonetheless.
  • It Can Think: The problem of Hedlok all comes back to this. ARMS Labs believed that it'd be possible for a fighter to control six ARMS if they made the apparatus instead worn on the head to increase motor cognitive activity. And then Hedlock developed independent thought...
  • Killed Off for Real: If defeated on Level 6 or 7, his host and creator Dr. Coyle destroys Hedlok in rage.
  • Leitmotif: A foreboding rock song with various vocal soundbytes (most prominently a metallic groan) that, unlike other songs in the game, does not remix the game's main theme. Elements of this song are mixed with Max Brass's theme to make a new song for his battle in Grand Prix, but the dark guitar riff and metallic groan do show up before the battle starts.
  • Meaningful Name: It's a head that locks itself onto the bodies of other fighters.
  • Multi-Armed and Dangerous: Has two pairs of spring arms which combine with the two arms of whoever wears it to give six arms total.
  • Oh, Crap!: After being thwarted in the Grand Prix and having its ARMS blown off, Hedlok launches itself off the champion and into the horizon, presumably to get the heck out of there ASAP. On Levels 6 and 7, he simply deactivates, leading to Dr. Coyle removing him directly from her head and taking out her frustration, destroying Hedlok for good.
  • Power Copying: Hedlok itself has four spring-type ARMS, but by itself they serve no purpose. When it's chosen a body, however, its ARMS absorb the attributes of those whomever it's taken, giving itself either six of the same type or three ARMS apiece.
  • Psycho Prototype: It was being developed by the same enigmatic ARMS Research Lab that was responsible for Helix and the DNA Man line to be used as a sparring machine...and then it got out.
  • Rapid-Fire Fisticuffs: While this trope applies to all fighters in terms of their Rush, Hedlok is unique in that this is its grab, dragging opponents in for a furious beatdown.
  • Red Eyes, Take Warning: Hedlok has glowing red eyes.
  • Roar Before Beating: Hedlok begins every match giving a shockwave-producing roar, before the immediately-ensuing six-ARM beatdown. His Level 8 battle theme after the 5.0.0 update also starts off with an angry roar from Hedlok.
  • Robot Athlete: He's a robot boxer with four arms.
  • SNK Boss: Hedlok fights with six arms, has lots of health, and uses the secondary abilities of whichever fighter it combines itself with. Its Limit Break is also far, far stronger than the Limit Breaks of any of the playable fighters. Downplayed in multiplayer due to the fact that Hedlok is fought 3-on-1, evening the odds, but played very straight in the Grand Prix if you're playing solo.
  • Time-Limit Boss: Averted. In Grand Prix mode, the time limit is set to infinite (unlike every other battle, including Max Brass), meaning reducing his HP to 0 is the only way to beat him. Justified as Hedlok clearly isn't interested in playing by the League's rules, and only wants to beat the crap out of you.
  • Timed Mission: When engaging Hedlok in online multiplayer lobbies. If the timer runs out, it's considered a loss for the team of three challenging Hedlok no matter how much health it has left.
  • Training Dummy: The predecessor device to Hedlok was designed for sparring partners to bring out the full potential of fighters and be worn over the torso like armor. However, Dr. Coyle deemed it too difficult for humans to control all of its ARMS and decided to make a followup that would be worn like a helmet, had AI and fought for the fighter wearing it. And then it went downhill from there.
  • True Final Boss: On levels 1-3 in Grand Prix, you beat Max and take home the title. Play on level 4 and higher, and Hedlok pulls an Akuma, taking Max's or Coyle's body and giving you one final super-challenging opponent. And what makes him so challenging? The fact that he is the only fight in the Grand Prix where there is no timer; it's KO or be KO'd.
  • Wave-Motion Gun: Hedlok's Rush is a giant orb that it shoots from it's mouth, dealing huge damage.note 
  • Your Head Asplode: After beating it down to save Max Brass, Hedlok's internal mechanisms give off an intense violet light before resulting in an explosion that destroys its four ARMS. Hedlok then bursts off of Max's head into the horizon. On Levels 6 and 7, Dr. Coyle removes and destroys Hedlok out of frustration.

    The Cell 
Prototypes of Helix made by ARMS Laboratories. They are the enemies fought in 1-on-100 mode.
  • Blob Monster: They're made of a fragile black substance which is similar to Helix.
  • I Am Legion: Every known quote from The Cell is from 1-on-100 mode in the DNA Lab, and is exclusively in this form. It is made more alien by the fact that it's also in all caps.
  • Hive Mind: Implied by their legion speak and pitying the player for being "lonely".
  • Multi-Mook Melee: In 1-on-100. They start out practically inert and get more aggressive as you continue.
  • One-Hit-Point Wonder: Just one punch or grab is enough to defeat each of them individually. Until you get to number 100.
  • Training Dummy: Played with. In Warm-Up in Party Match, they're not invincible but they come in an endless stream and won't attack you: they don't even have weapons. If you're lucky a golden target will show up worth 1 currency.



How well does it match the trope?
