    "Gearless" Joe/Junk Dog 

"Gearless" Joe/Junk Dog

Voiced by: Yoshimasa Hosoya (Japanese), Kaiji Tang (English), Arturo Cataño (Latin American Spanish)
They don't make tombstones for stray dogs.

A man with no real name past his ring name, he scraped off a living by throwing fights in the underground Megalo Box matches... a fact which frustrated him to no end, which he expressed in destructive behavior.

  • Adaptational Nice Guy: Junk Dog is a Yabuki Joe analog from Champion Joe, but needless to say, while he shares many of his attributes, he lacks the original's sexism and general nasty attitude. This is also exemplified in their respective Animal Motifs: Joe was associated with bulls due to his anger issues, while Junk Dog is associated with stray dogs.
  • Animal Motifs: He embodies the toughness, ferocity, and freedom of a stray dog: he's an amazing boxer, but he also tends to disobey Nanbu's orders to throw a fight.
  • Badass Biker: Joe drives (recklessly) a sweet motorcycle at extremely high speeds to get around. He often crashes said bike.
  • Badass Normal: His "Gearless" gimmick on the way to Megalonia. He has to contend with boxers with vastly enhanced strength and speed with nothing but his own power, durability, and determination. In Megalonia, he tries fighting with Gear on, but it breaks down during the fight. He still manages to defeat Glen Burroughs without it, proving that he's really that tough.
  • Berserk Button: He absolutely hates fixed fights and taking dives.
  • Blood Knight: His defining trait is his love for a good fight. In fact, his drive to fight Yuri boils down to him wanting to see if he'd survive the challenge.
  • Charles Atlas Superpower: Joe withstands punches from boxers A) above his weight B) having their punches immensely enhanced by machinery with zero protection and somehow still stands.
  • Color Motif: Associated with the colour red, both in his red boxing gloves, red after-trails on his eyes and fists, and his tendency to bleed all over the place.
  • Counter Attack: Joe's trademark is to get in one good shot while the opponent is attacking him, which is what wins him most of his matches.
  • Covered with Scars: Has several scars on his whole body.
  • Determinator: As Nanbu points out, Junk Dog will not give up.
  • Distinguishing Mark: While he's Covered with Scars, the one most featured is the J-shaped one on his left cheek that he received from Yuri.
  • Drives Like Crazy: Puts himself in real danger through reckless driving to cool off from fixed matches. Once he fights Yuri for real, he finds that doesn't do it for him any more.
  • Dub Name Change: In the Latin American Spanish dub, he is named as "Perro Callejero" (literally, "Street/Stray Dog"). Likewise, "Gearless" Joe is translated as "Joe el Limpio" (Joe The Clean One) as in the sense he is clean of any kind of Gear.
  • Freak Out!: During his fight with Shark Samejima. After a single blow from his opponent lays him out flat, he succumbs to fear for the first time and ends up on the ropes for the majority of the fight.
  • From Nobody to Nightmare: He was almost literally a nobody (no social security number and apparently not even a name) in the world of underground boxing before blazing through the Megalonia championship to earn himself a spot as one of the most promising fighters of the championship.
  • A Hero to His Hometown: The people from the ghetto he lived in are shown to absolutely worship him (getting tattoos and making rap songs based on him) once he makes a name for himself in Megalo Boxing.
  • Homeless Hero: He appears to just crash by in the houses of friends and supporters. Notably, when Megalonia starts he sleeps in Nanbu's trailer.
  • Hot-Blooded: Very enthusiastic where boxing is concerned and is very open about his emotions.
  • I Shall Taunt You: Good at bluffs and button-pressing, as he demonstrates against Aragaki and Mikio.
  • Jobber: Before deciding to rebel and fight for himself, his role was to provide convincing but rigged matches that he'd always lose.
  • Leitmotif: A kickass synthetic beat that also serves as the show's main theme. This is also his entrance music as a professional boxer (as shown here), making it a In-Universe case as well.
  • Lightning Bruiser: His boxing style consists on a combination of using his lightning speed to dodge and counter with extremely powerful punches, though he's also extremely resilient.
  • Made of Iron: Joe regularly suffers wounds brutal enough to cripple most real life boxers but keeps on going by sheer force of will.
  • Memetic Badass: In-Universe, Joe quickly gains traction as being the only Gearless boxer. This combined with his Working-Class Hero image due to coming from the slums makes him into something of a living legend with others from the ghetto.
  • Not Afraid to Die: Similarly to a certain famous anime character with the same hairdo, Junk Dog is defined by his complete nonchalance towards death and being hurt. His entrance video on Megalonia calls him "Fearless!".
  • Rebellious Spirit: Part of his main animal motif of a stray dog is that he rejects all norms placed on him by simply being frustrated from being quiet and doing what he's told. Which causes him to go on his journey to fight Yuri.
  • Shout-Out: His name, "Gearless" Joe, is more than likely a direct allusion to "Shoeless" Joe Jackson, a legendary baseball player.
  • Spared by the Adaptation: He doesn't get his original counterpart iconic death, living after his fight with Yuri.
  • Underestimating Badassery: Back in the underground boxing, everyone thought he was just a regular Jobber until he flipped the script and decided to start winning. When he's in Megalonia, most opponents tend to underestimate him because he doesn't use Gear.
  • Weak, but Skilled: As a Megalo Boxer, "Gearless" Joe being... well, Gearless, means he can't rely on a Power Fist to aid his strength and makes him dependent on heavy slugging blows to deal damage. On the plus side, he has incredible stamina from drawing out (fixed) boxing matches and doesn't have to wait on the Gear's response time when attacking or blocking.
  • Working-Class Hero: In contrast to most other Boxers we meet in the series, Joe comes from the absolute gutter (to the point he doesn't even have a social security number). His ring entrance video even refers to him as "The Man from Wilderness".
  • Work Off the Debt: Joe is indebted to the Mob (much like Nanbu) in a vicious cycle (i.e the only way to pay off previous debt is by getting more in-debt).
  • Worthy Opponent: Considers Yuri one almost from the get-go and spends the entire show trying to earn the same distinction from him. He also expresses similar thoughts against Aragaki and considers it a shame he didn't get to legitimately KO him.


Gansaku Nanbu

Voiced by: Shirou Saitou (Japanese), Jason Marnocha (English), Humberto Vélez (Latin American Spanish)
I'll show you exactly what we frauds can do!

Junk Dog's trainer, fixer and longtime partner, who arranges the fights Junk Dog fights in and takes marching orders concerning their outcome.

  • Accent Adaptation: In the Latin American Spanish dub, he speaks with a very thick Mexico City accent, in a way to depct his lower-class origins.
  • Adaptational Nice Guy: He's essentially Danpei from Ashita no Joe, but without the rep of alcoholism and abusiveness towards his charges in the boxing league. The ease with which he's able to enter Joe into the official rankings suggests he still has rep in the boxing world and the only person with ill will towards him is Aragaki.
  • Adaptational Villainy: On the flip side he's also a more selfish and morally grey person who uses Junk Dog/Joe for his own ends and has to be forced into taking their game to the pro level. He ultimately redeems himself, but at the cost of his remaining eye.
  • Animal Motifs: Fujimaki likens him to a scorpion and even tells him the story in episode 10.
  • Character Development: His arc involves regaining faith in boxing (and subsequently, in himself and in Joe) after having hit rock bottom.
  • Despair Event Horizon: When we first meet him, he's a drunk fraud who rigs fights. But we later see he used to be a fairly prosperous coach, before his prized pupil seemingly died in a battle. It's strongly implied one thing led to the other. Luckily, Joe snaps him out of it over the course of the show.
  • Eyepatch of Power: Like Danpei, he is missing an eye, but he's still a good boxing coach and able to give Joe practice in the ring.
  • Eye Scream: Lost an eye to settle a debt to Fukimaki. He ends up gouging out the other one himself in order to allow Joe to fight for real instead of throwing the match.
  • Handicapped Badass: It's actually very surprising that he still manages to be highly effective boxing coach with an eye missing, given that this would take away his depth of perception (a crucial factor in boxing). Even going completely blind doesn't stop him from hearing Joe isn't distributing his weight properly and calling him out on it.
  • Heroic Sacrifice: It's a running point of discussion if Nanbu would sacrifice himself for Joe or if he's just in it for himself. Ultimately, he rips out his own eye (becoming completely blind) just to save Joe.
  • Failed a Spot Check: Apparently never noticed that his former star pupil was currently sitting in the top 20 boxing rankings. Sachio calls him out on it in episode 5.
  • Fatal Flaw: His carefulness and tendency to give up. He ends up butting heads with Joe repeatedly over when to fold them, considering the latter's Determinator attitude. This leads him to punch out Joe in episode 7, causing him to forfeit his match rather than risk having Joe's forged ID found out.
  • Guile Hero: Nanbu is highly cunning and perceptive when both when it comes to boxing strategy and when it comes to actual PR and social relations.
  • Heel Realization: Much of Nanbu's character growth comes through realizing he's wronged people and trying to make what amends he can for it. He manages to somewhat mend fences with Aragaki, and ultimately sacrifices himself to let Joe off the hook.
  • Jerk with a Heart of Gold: He may act grumpy and overbearing towards his charges, but he's also shown to care genuinely about them.
  • The Mentor: To Joe, obviously, and previously to Aragaki.
  • My Greatest Failure: When he believed Aragaki had died in the war, Nanbu fell into a deep depression and closed his gym. Realizing that Aragaki was alive all this time and he never tried to find out makes Nanbu feel deeply guilty about it.
  • Retired Badass: it's strongly implied Nanbu used to be a boxer just like his Ashita no Joe counterpart, and he clearly still has enough athleticity to be one Hell of a trainer. Best shown when he is able to fight and take down several of Fujimaki's bodyguards (who are far younger and fitter than him).
  • Sir Swearsalot: He is especially more foul-mouthed in the Latin American Spanish dub, when he swears at any chance he had.
  • The Social Expert: He has shown a ability to read everyone around him like a book, being able to masterfully play the PR game to get Joe to the top rankings and also easily play on Yukio's emotions when the time comes.
  • The Strategist: As Joe's cornerman, he is often analyzing the fight strategically and suggests tactical choices to Joe.
  • Team Dad: For Team Nowhere.



Voiced by: Michiyo Murase (Japanese), Erica Mendez (English), Leslie Gil (Latin American Spanish)
I'm not some kid who can't pull his own weight...

A street kid and leader of a small gang of orphans, who is also a Megalo Boxing fan. He is hired by Joe and Nanbu as assistant coach for the team.

  • Ascended Extra: In a way. In Champion Joe, Sachi and the street kids served the purpose of showing Jerkass Joe's nicer side as his Morality Pet, but were still secondary characters, filler episodes notwithstanding. Sachio, on the other hand, is the third member of Team Nowhere, making him also a Composite Character, taking Nishi's role.
  • The Artful Dodger: Seems to have no problems being a street rat.
  • Because You Were Nice to Me: Starts hanging around Team Nowhere after Joe steps in to save him from a drug dealer.
  • Berserk Button: Stay away from his hat.
  • Composite Character: Sachio is Sachi, the most relevant of the street kids who follow Joe around, combined with Nishi, the third member of Joe's group in Champion Joe.
  • Gender Flip: To Sachi.
  • The Heart: His main skill is in getting Nanbu and Joe to cooperate by not being afraid to call both of them out on their crap.
  • Mouthy Kid: Just like Nanbu, Sachio is also especially foul-mouthed in the Latin American Spanish, which is especially unusual there.note 
  • Nice Hat: Wears Joe Yabuki's iconic hat, which is implied to be a gift from his (deceased) parents.
  • Not So Different: Has a minor breakdown over the fact that he's just been using Joe for revenge much as Nanbu has been using him to clear his debts. He gets over it in time to tell Joe to stop trying to match-fix.
  • Revenge: The Shirato corporation stole his father's designs and killed him. He sees helping Joe win Megalonia and humiliate the corporation as a way of getting revenge.
  • Tagalong Kid: To Team Nowhere, though he turns out to be a skilled motivator and surprisingly knowledgeable about Megalo Boxing.

Shirato Corporation



Voiced by: Hiroki Yasumoto (Japanese), Lex Lang (English), Jose Arenas (Latin American Spanish)
I'll grant that request of yours... And show you real Megalo Boxing.

The Shirato Group's champion Megalo boxer. Currently rated first in the ranking system, and therefore the favourite to win the four-man Megalonia tournament.

  • The Ace: Lays out Junk Dog in less than three minutes in their first match, and is repeatedly touted as the finest boxer in the tournament.
  • Animal Motifs: While Joe is likened to stray dogs, Yuri is likened to a pure-breed silver dog he owns. Much like a purebred, he's been groomed to be the best Megalo Boxer ever, and he's also obedient to the will of the Shirato corporation just like a well-trained dog. Yet, as his dog shows in the second episode in a subtle bit of Foreshadowing, even a trained dog can want the freedom to exert themselves, which Yuri proves when he fights Junk Dog without his Gear on his personal terms.
  • Awesomeness by Analysis: He's able to read Junk Dog instantly, basically letting him see through all of the latter's moves. He's able to tell Joe is in a fixed match in episode 11 just from seeing the first round.
  • Badass Baritone: Yuri has an extremely deep voice that adds to his sinister-ness.
  • Blood Knight: Like Joe, in the end what he wants the most is a good fight. When Pepe Iglesias actually managed to land a punch on him, Yuri's reaction is to smile.
  • Body Horror: After having his Gear removed, his arms and shoulders are covered in raw pink tissue where his Gear interfaced with his body.
  • Boring, but Practical: One of his nicknames is "Mr. Classic", and his fighting style is considered orthodox by Megalonia's commentators. Considering he's undefeated, this doesn't lessen his effectiveness any.
  • Brought Down to Badass: After using Shirato's integrated Gear for most of the series, he elects to have it surgically removed so he can fight Joe on equal footing. He is no less skilled a boxer without his Gear, and his final fight with Joe is a match for the ages.
  • Color Motif: Purple. It's the color of his eyes, his boxing gloves and his prosthetics glow purple.
  • The Champion: Yuri (aside from being an actual undisputed champion is boxing terms) stands as the champion for Yukiko, dedicated himself entirely to her and her objectives.
  • Cyborg: Uses a Shirato top-of-the-line integrated gear built into his arms and shoulders. Part of his job seems to be as display dummy for their products.
  • Expy: Out of all the characters, he is the most similar to his inspiration, being a clear analog of Toru Rikishii from Champion Joe, with the only differences being him being foreign instead of Japanese, and never considered a criminal (As Rikishii and Joe met in jail). He shares the character acting too, and exactly like Rikishii he handicaps himself before his fight against Joe.
  • Foil: Despite his cold and aloof demeanor in contrast to Joe's more scrappy behavior, they're ultimately very similar.
  • Grin of Audacity: It's very rare, but he cracks a almost imperceptible grin in moments of some semblance of tension to him, usually when facing Joe.
  • Honor Before Reason: He becomes so obsessed with finally fighting a worthy opponent that he sacrifices his career, his physical comfort, and his mobility.
  • Kubrick Stare: Does this when he gets serious, complete with camera close-up.
  • I Owe You My Life: It hasn't been explained in-depth what he means by it, but he tells Joe his loyalty to Yukiko stems from her "saving his life" when he needed it most. While recuperating, Yuri admits to Yukiko that she gave him a reason to live.
  • Leitmotif: A In-Universe and out of universe one. He has a bone-chilling a heavily synthetic song that is used for dramatic scenes featuring him and in his entrance video during boxing matches.
  • Let's Get Dangerous!: Both with Joe and Pepe Iglesias, he at first plays the fight more calmly. When his opponent lands a solid hit or comes close to, Yuri suddenly switches in high-gear and proceeds to unleash Hell.
  • Lightning Bruiser: He has no real 'gimmick' to his boxing besides being just plain good in every category. He's able to win matches with the first blow that lands, blocks blows from both Joe and Pepe with little reaction, and that's on the off-chance someone gets through his guard in the first place.
  • Macho Masochism: After having his Gear removed, Yuri is in excruciating pain for days. He refuses the painkiller that Mikio offers because, by his logic, if he can't handle his post-surgery pain, he won't be able to handle the pain of fighting Joe.
  • Made of Iron: Even de-Geared and suffering from an autoimmune reaction to his surgery, he goes 13 rounds with Joe and survives.
    • Subverted in that the ordeal leaves him physically disabled.
  • No Celebrities Were Harmed: He was likely based partly on boxing heavyweight legend Wladimir Klitshiko. Besides a remarkable physical resemblance, both are cold, cerebral boxers noted for their more stoic behavior and ability to deliver sudden K.Os who reign as undisputed champions.
  • Not So Different: He's equated to a dog, just like Joe, but a well-trained champion dog with an owner (Shirato) instead of a stray dog who has to fight for scraps. Ultimately, neither men are able to fight for their own sake.
  • Purple Is Powerful: Yuri's Color Motif is purple, from his boxing gloves to his eyes, as befitting of his Red Baron "King of Kings" as boxing royalty.
  • The Quiet One: While he does talk (usually with Joe or Yukiko), he's still rather terse and laconic.
  • Reality Ensues: In real life, physically punishing sports such as boxing can leave athletes with lifelong physical health problems. His second fight with Joe leaves him physically disabled and confined to a wheelchair.
  • The Red Baron: His ring name is "King of Kings", though it's never used outside of official announcements.
  • The Rival: To Junk Dog, though somewhat one-sided at first as Yuri starts out at number one and Junk Dog can't even enter the Megalobox rankings due to a lack of citizenship, but Yuri starts to respect him once he sees him in action. He's also a rival to "Ace" Murata, who seeks to prove his type of Gear is better than Yuri's.
  • Signature Move: His right hook, which is lampshaded in the flashback he meets Yukiko. It scores him a victory by KO against Junk Dog and Pepe, but Joe survives it in their final match.
  • Spared by the Adaptation: Unlike Rikishii, he lives after his fight with Joe, but is left crippled.
  • The Stoic: He's never shown to lose his temper or even get upset during the show, much like Yukiko. At best, you'll see him smirk in particularly dramatic moments.
  • Undying Loyalty: He is loyal to a fault to his master Yukiko. Subverted in the end when he chooses to de-Gear after Yukiko has fulfilled her contract, seeing a proper match against Joe as more important.
  • Worthy Opponent: Despite calling Junk Dog a "stray" in their first encounter he seems genuinely happy that Joe went to all that effort for a proper rematch.
    Yuri: The man who taught me Megalo Boxing told me something. "If you're lucky enough to run into a fighter in your generation whom you want to win against, from the bottom of your heart, consider yourself blessed. If you ever find someone like that, never let him out of your sight." I've finally met the opponent he was talking about.


Yukiko Shirato

Voiced by: Nanako Mori (Japanese), Erika Harlacher (English), Claudia Contreras (Latin American Spanish)
Who is the true champion? That will be revealed in the ring of Megalonia.

CEO of the Shirato Group, who runs the Megalobox system and organized the Megalonia tournament, and also manufactures the Gears used by many of its boxers.

  • Affectionate Nickname: Yuri calls her "owner", which she doesn't seem to mind.
  • And the Adventure Continues: The Stinger reveals she re-starts Megalonia in search of a new champion after Joe and Yuri's retirements.
  • Corporate Samurai: Brutal in her CEO dealings, but still has a integrity of her own.
  • Friend to All Children: Despite her cold CEO persona she's shown to be very open and friendly to children, including Sachio.
  • Honest Corporate Executive: Yukiko is ruthless in her business, but she seems to abhor foul play of any kind. She also sees Gear as the way to the future and wants to be a part of making a better tomorrow.
  • Ice Queen: Very cold and very aloof towards anyone who isn't Yuri.
  • I Have No Son!: Disowns both Yuri and Mikio in episode 12 by telling them they're no longer part of Shirato.
  • Iron Lady: She runs a tight ship in her company, letting no one stand in her way.
  • Non-Idle Rich: Yukiko is a very active businesswoman and inventor.
  • Pet the Dog: She comforts Yuri while he is in excruciating pain after having his Gear removed. She touches his head and hand and offers to take him back "home" to Shirato to have his Gear reattached.
  • The Proud Elite: Extremely proud of her company, and her main drive is to enhance that company's status.
  • Rich Bitch: Downplayed but still present. While Yukiko is not a bad person, she is still very classicist and sneering towards the poor.
  • Screw the Rules, I Make Them!: Quotes the trope name more or less verbatim (if more politely) in episode 8 when she decides on the fly to let Joe have a shot at fighting Mikio.
  • Secret Keeper: She discovers Joe's ID is faked in the penultimate episode, but decides not to do anything about it.
  • The Stoic: She is cold and hardly emotes, having the attitude of a proper businesswoman.
  • The Spock: She views Megalonia as a PR stunt for Shirato Gear and genuinely can't understand Joe and Yuri's Blood Knight natures. Thus, Yuri removing his Gear or Joe fighting his way to the finals with a forged ID with no financial motive are actions that make no sense to her.
  • You Have Failed Me: In something of a Pet the Dog moment, when Yukiko discovers the 'irregularities' behind Sachio's father and his subsequent death she orders everyone associated with the project 'dealt with'.
  • You Have Outlived Your Usefulness: A relatively non-malicious example but Yukiko decides to cut off ties with Yuri after he has his gear removed. The entire reason Yukiko held the Megalonia tournament in the first place was to market the utility of the gears and since she was still able to successfully sell them, she decided not to pull the plug on the now gearless final match.


Mikio Shirato

Voiced by: Tatsuhisa Suzuki (Japanese), Robbie Daymond (English), Carlos Luyando (Latin American Spanish)
Megalonia is no place for stray dogs.

Yukiko's brother and current rival for the leadership of the Shirato Group. Also a professional boxer in the Megalobox system, where he is ranked eighth.

  • Ace Custom: Boxes using a custom-built Gear with an experimental AI called "Ace" inside, which he improves on after every match.
  • Achilles' Heel: Mikio relies on "Ace" to the degree that he's practically one with his AI. Joe exploits this by refusing to take a stance during round 4, leaving "Ace" with no input and forcing Mikio to take over.
  • Animal Motifs: Notable as the main aversion, being the only boxer in the story who is not associated with an animal. After all, he's not a real boxer at all, but an Engineer.
  • Awesomeness by Analysis: The crux of his boxing style: "Ace" predicts the opposition's moves and lets him respond a millisecond faster than other Gear-using boxers could.
  • Badass Bookworm: He's a brilliant engineer first and a professional boxer second.
  • Cain and Abel: While both him and his sister are very ruthless, Mikio is by the most malevolent.
  • Determinator: All qualities aside, he is extremely driven in his goals, which is where he finds common ground with Joe.
  • Evil Counterpart: If his sister is a brilliant, ruthless and aloof businesswoman with a moral backbone, Mikio is all that except almost completely amoral.
  • The Engineer: Developed his own Gear and constantly improves on it.
  • Fatal Flaw: His overconfidence and over-reliance in his own technology is his central problem. When he finally realizes that he has to make his own decision with his final attack, Joe sees through it.
  • Foil: He's shown to be one to Yuri: Mikio emphasises the 'Gear' in 'Gear-equipped boxer', while Yuri emphasises the 'boxer'. To Yuri, the Gear is a tool to aid the boxer and what counts is that the one wearing is 'the real deal', while to Mikio the Gear is a part of the boxer, including in decision-making. This makes Joe, who has no Gear at all, his natural antithesis.
  • Fragile Speedster: Due his A.I predicting the movements of his opponents, he's effectively untouchable and hits flurries of punches with impunity as a result, but he doesn't pack a particularly strong punch or show any particular resilience. Indeed, all it takes is one well-placed uppercut by Joe and he's down for good.
  • Graceful Loser: For all of his Smug Snake demeanor, he actually takes his loss to Joe really gracefully.
  • Heel–Face Turn: Returns in episode 12, where he helps Yuri and even establishes something of a rapport with him. In his own words, he's 'slowly rebuilding'.
  • Hidden Depths: While we first see his character as a cold-hearted and ruthless man, we eventually learn more about what makes him tick and his own sense of morality like a legitimate desire to win.
  • Powers Do the Fighting: His gear does the fighting for him. Of course, his high-end gear and its AI are the product of his own genius, so the point can be argued.
  • The Proud Elite: Wealthy, haughty, cold and dismissive of others.
  • The Red Baron: His ring name is "The Fighting Engineer". He's often called "Ace" as well (the name of his AI).
  • The Resenter: Is driven almost entirely by resentment over his sister's success in Shirato outweighing his.
  • The Rival: To Yukiko. His AI-equipped Gear was proposed as an alternative to Yukiko's integrated model, and he was the other main candidate to become CEO of the Shirato Group. By proxy, he also rivals Yuri since both of them are boxers claiming to have "the perfect Gear".
  • Smug Snake: Smug and dismissive of those who oppose him, and not below using methods like blackmail to climb the rankings.
  • The Unfavorite: He was passed over for the leadership of Shirato (which instead went to his sister), causing his resentment.
  • The Unfettered: Mikio wants to succeed, and he doesn't care if he has to stoop very low or even go against his own sister if he has to.
  • Weaksauce Weakness: How do you defeat an AI that can learn and counter all of your moves? By doing absolutely nothing for several rounds, giving it no input to analyze and effectively turning the extremely advanced Gear into a hunk of metal weighing Mikio down.

Megalo City Veterans' Association


Tatsumi Leonard Aragaki

Voiced by: Makoto Tamura (Japanese), Greg Chun (English), Arturo Mercado Jr. (Latin American Spanish)
It's time for you to pay your portion of the debt for the things I've lost.

Former war veteran and Nanbu's star student when he was running a gym. After losing both his legs to an IED, Aragaki returned to Megalo city and began boxing for a veteran's association, using prosthetics instead of legs. He is ranked seventeenth in the Megaloboxing ranking.

  • Achilles' Heel: His issues with Nanbu leaves him very conflicted and open to psychological attack by Joe. Also, his legs are about to give out on him, meaning he can't keep boxing for much longer.
  • Artificial Limbs: Wears metal prosthetics below his knees to replace his lost legs.
  • Animal Motifs: Butterflies, as seen below. His boxing style involves a lot of the 'float like a butterfly' aspect of boxing.
  • Butterfly of Death and Rebirth: Hallucinated one as he lay dying from the IED, and later had one tattooed on his chest as a reminder.
  • Composite Character: Of two Ashita no Joe characters, combining Danpei's former student (and source of My Greatest Failure) with one of Joe's opponents. Ultimately he's more a foil to both, however.
  • Defeat Means Friendship: Holds no ill will towards Joe or Nanbu after forfeiting, and is seen cheering Joe's victory over Mikio with the rest of his team.
  • Good Scars, Evil Scars: Half his face is scar tissue, and he's presented as a conflicted person.
  • Handicapped Badass: Ranked seventeenth despite his handicap, and considered a good shot for the fourth slot of Megalonia.
  • Foil: Serves as one to Kim Yong-bi from Ashita no Joe. Both are skilled boxers and former Shell Shocked Veterans whose lives were ruined by war, but Kim is a Jerkass The Stoic who looks down at boxing as a game after his wartime experiences, while Aragaki is a decent man consumed by revenge whose life was literally saved by being able to box again. Kim gets a karmic defeat courtesy of his Joe, while Aragaki manages to let go of his grudges and willingly forfeits.
  • Game-Breaking Injury: His legs give in halfway through round 4, which would have made him unable to continue even if he hadn't willingly forfeited. When Nanbu meets him after the match, the rims of his prosthetics are covered in blood.
  • Graceful Loser: Forfeits the match after the fourth round, because he's been able to work out his issues and his legs were giving out anyway.
  • Lightning Bruiser: Faster than Joe and almost as good at taking hits, with incredible reach and footwork. His main weakness is that the prosthetics limit the weight and power of his Gear, making him only about as strong as a non-geared boxer. And also that his knees are about to give out on him because of the strain boxing puts on his legs.
  • Pocket Protector: A somewhat dark example. Nanbu gave him a (losing) gambling ticket before he shipped out (Nanbu had hoped to win money for a farewell dinner with it), joking that maybe it would stop a bullet. The ticket fell out of Aragaki's jacket as he was about to kill himself, causing him to break down and be unable to go through with it.
  • The Red Baron: His ring name is "Stayin' Alive", which like Yuri's is only used in In-Universe promotional material.
  • Revenge by Proxy: Tries to get revenge on Nanbu by pulverizing his student in the ring. Joe has to point out to him that he's actually fighting him, not Nanbu.
  • Shell-Shocked Veteran: Still suffers nightmares. Being able to box seems to be his main way of coping.



Voiced by: Youhei Tadano (Japanese), Jake Eberle (English), Armando Rendiz (Latin American Spanish)
You need to leave the past in the past.

A former war veteran and the main trainer of the Association, and thus by extention Aragaki's.

  • Artificial Limbs: His right hand is robotic, with the implication he lost it in a war.
  • Cool Old Guy: Genuinely cares about his student and is not afraid to call him on his outbursts. It's implied he helps train war veterans as boxers as a way of lowering suicide rates.
  • Foil: Like Aragaki is a foil to Kim-Jong Bi, Miyagi is a foil to the Colonel who trains Kim. Instead of pushing Kim over the edge by focusing on winning, Miyagi guides Aragaki into retiring with grace.
  • No Celebrities Were Harmed: Has an uncanny resemblance to Jacques Costeau of all people, complete with a woollen hat.
  • What the Hell, Hero?: Gives a very subdued one to Nanbu when he tells him a single phone call to confirm Aragaki's death could have avoided all the sorrow the two have been through since.




Glen "Bloody Lion" Burroughs

Voiced by: Enrique Cervantes (Latin American Spanish)note 

An American Megaloboxer, third in the rankings and the third boxer picked to fight in Megalonia.

  • Animal Motifs: Obviously, lions. Fitting the association, he has the ferocious power of a lion and the pride associated with "the kings of the jungle".
  • Arrogant Kung-Fu Guy: He's a highly talented boxer, but also very cocky and treats everyone with some disdain.
  • Badass Boast: "I will smash you into junk, together with your sleazy gear." True to his word, his punches quickly start shattering Joe's gear.
  • The Berserker: Burroughs batters his opponents with neverending violence but relatively little strategy (which makes him prey for Joe's counter-punching).
  • The Brute: You don't get a nickname like "Bloody Lion" for being soft. Burroughs honors his cognomen by being brute strength personified in and out of the ring.
  • Color Motif: Most of his character is associated with yellow or gold, resembling a lion's mane.
  • Eagleland: He enters the ring on the back of a monster truck, for Pete's sake.
  • Hot-Blooded: Burroughs is quite aggressive both in fighting style and personality.
  • Hot Blooded Sideburns: Has a distinctive pair of sideburns and is by far the most aggressive fighter in Megalonia.
  • Gratuitous English: Speaks in Surprisingly Good English.
  • Leitmotif: His theme (as shown in his ring entrance video) is a brutal guitar riff alongside bestial howls and roars, suiting his violent nature.
  • Mighty Glacier: He's a heavyweight, which is considered a handicap in Megalo boxing because Power Fists lets lighter, faster boxers punch way above their weight class. In his bout against Joe, he seems to No-Sell most punches Joe throw his way, while he clobbers him strongly enough to shatter steel, but Joe is clearly far quicker and more agile.
  • Muscles Are Meaningful: Burroughs is clearly muscled enough to be a heavyweight fighter and has the strength to match.
  • Overshadowed by Awesome: The announcement of his entry into Megalonia gets overshadowed by Joe's latest victory, and the story treats him mostly as a side character at best. He's also never shown as a serious danger to Joe, with Fujimaki's desire to fix the match being treated as the real obstacle of their fight.
  • Phenotype Stereotype: Blond, blue-eyed and towers over the other boxers.
  • The Red Baron: His ring name is "Bloody Lion" for his offensive fighting style.
  • Smug Super: Big, almost absurdly strong, and also quite arrogant.


Pepe "Spider" Iglesias

Voiced by: Alejandro Saab (English), Beto Castillo (Latin American Spanish)

A Mexican Megaloboxer, second in the rankings and the second dead-lock for the Megalonia after Yuri. He's matched against Yuri in the semi-finals.

  • Animal Motifs: Spiders, evidently. The commentators explain (just as he's showing us) that Pepe fights with flexible movements and using unexpected angles to trap his opponents, thus being likened to a "spider's web".
  • Badass Boast: "¡Te voy a matar, campeón!" ("I'm gonna kill you, champion!"), to Yuri. Yuri proves him very wrong.
  • Badass Mustache: While Bloody Lion Burroughs has sideburns, Pepe is rocking a pencil mustache.
  • Calacas: Uses Mexican sugar skulls/Calacas prominently in the shoulder pads of his Gear. He uses them even more extensively in his entrance, in which he walks to the ring with a Calaca mask followed by a Calaca parade.
  • Cheshire Cat Grin: Pepe smirks like he knows something you don't.
  • Curb Stomp Cushion: He's defeated early in the second round of his bout with Yuri after a powerful hook. However, beforehand, he did manage to put Yuri on the ropes and land a solid punch on him.
  • Dance Battler: Uses long reach and a high-energy fighting style to leave his opponents guessing.
  • Dashing Hispanic: He's very suave and witty.
  • Deadpan Snarker: Has a bit of fun and snark at Joe and Yuri.
  • Dreadlock Warrior: Wears his dreadlocks in a bun, and is quite a fearsome boxer.
  • Fragile Speedster: Relies on not being hit in the first place, as Yuri demonstrates.
  • Gratuitous Spanish: Speaks entirely in (surprisingly accurate) Spanish.
  • Latino Is Brown: Notably the only dark-skinned character of the main cast and the only Latino.
  • Leitmotif: Like all other fighters, he has his own theme (shown in his entrance music video) in the form of a snazzy trumpet number that perfectly represents him.
  • Masked Luchador: He's a boxer, not a luchador, but he pays homage to the Mexican luchador by wearing a luchador-like outfit (namely a mask) in his entrance to the ring (he removes it for the fight).
  • Misplaced Accent: Despite being evidently Mexican, he has a Spanish accent. For obvious reasons, this was fixed in the Latin American Spanish dub, as it was done in Mexico.
  • No Celebrities Were Harmed: Pepe is probably inspired by MMA legend Anderson "Spider" Silva. Besides sharing a nickname, both are dark-skinned Latino (Silva is Brazilian while Pepe is Mexican) fighters known for a Dance Battler style to dodge everything and then destroy their opponents with unpredictable attacks from odd angles.
  • Perpetual Smiler: Always sporting a cocky grin. The only moment he's not smiling is when Yuri knocks him out cold.
  • The Red Baron: His ring name is "Spider" for his flexibility and tendency to attack from unexpected angles.
  • Rapid-Fire Fisticuffs: His fighting style relies on lightning-fast jabs and punches.
  • Sharp-Dressed Man: Outside of the ring Pepe is shown wearing a very dapper suit. He also wears a very nice coat in his ring entrance.
  • The Trickster: His fighting style relies on tricking and misleading his opponents, and his showboating personality lends itself nicely to that.
  • The Worf Effect: Despite being the second-ranked boxer he's defeated by KO in the second round just to show off how badass Yuri is, and his defeat is little more than a subplot of the episode he appears in.


Shark "Maneater" Samejima

Voiced by: Shinnosuke Ogami (Japanese), Tommy Modano (English), Ismael Verástegui (Latin American Spanish)

A professional Megaloboxer ranked 186th in the Megalobox rankings, way below his actual skill level due to fighting dirty. Joe's first opponent in the Megaloboxing rankings.

  • Animal Motifs: Sharks, in case it wasn't obvious from his name.
    • On a less (internationally) obvious note, Samejima (鮫島) is also an actual Japanese surname, literally meaning "shark island".
  • Dick Dastardly Stops to Cheat: The reason for his low ranking is that he constantly uses illegal blows even when he could win fairly, causing him to often be forced to forfeit matches. He even gets one unsportsmanlike shot in at Joe during their match.
  • Glass Cannon: Spends three rounds pounding on Joe before the latter manages to get over his fear, at which point Samejima goes down to a single counter.
  • Hair-Trigger Temper: Extremely short-tempered and spends the entire match on the offensive. Joe's usage of lighthearted footwork in the third round triggers this hard enough for him to attack recklessly and leave him wide open.
  • Starter Villain: He's essentially a way for Joe to cut his teeth on fighting gearless in a professional setting.




Voiced by: Hiroyuki Kinoshita (Japanese), Jamieson Price (English), Humberto Solorzano (Latin American Spanish)
A stray dog remains a stray dog, and a scorpion remains a scorpion.

A mob boss that runs the fixed matches Junk Dog fights in. He becomes the unofficial 'sponsor' of Joe and Nanbu's shot at Megalonia by providing them the fake ID needed to enter the tournament in return for their winnings.

  • Adaptational Villainy: He is Goromaki Gondo analog from Champion Joe. While Gondo was a NeighbourhoodFriendlyGangster, Fujimaki lacks the "friendly" part, being a firm manipulator.
  • Awesomeness by Analysis: Like his inspiration, he's very good at reading fights without being a fighter. He's able to tell that Joe is intentionally tanking hits from Burroughs to spite Nanbu's advice.
  • Evil Tastes Good: He's fond of cooking and discusses fine dining as an analogy for what he's really talking about.
  • Fatal Flaw: He doesn't believe in Character Development, believing that people essentially never change. This causes him to ignore Joe's drive to actually win and Nanbu's Hidden Heart of Gold.
  • I'm a Humanitarian: He implies not-so-very-subtly that he has people who failed him boiled down and used for soup stock.
  • It Amused Me: Combined with Evil Has a Bad Sense of Humor. He lets Joe and Nanbu off the hook at the price of an eyeball because he finds the irony of Nanbu blinding himself because he wanted to see Joe reach his full potential hilarious.
  • Nice Job Fixing It, Villain!: Might have pulled off his gambit in episode 11 if he hadn't constantly belittled Nanbu and Joe with Evil Gloating.
  • The Mob Boss Is Scarier: Nanbu is terrified of him, to the degree that he'll do almost anything to avoid getting on his bad side.
  • The Stoic: Always very calm and collected and never gets openly angry about anything.
  • Wicked Cultured: Enjoys cooking and fine clothing.
  • Villain Respect: He toasts Nanbu while watching the final match between Joe and Yuri, addressing him as 'Coach Nanbu' without his usual derisive tone and admitting that Nanbu managed to turn a fraud into the real deal.


Higachi Potemkin

Voiced by: Hisao Egawa (Japanese), Chris Tergliafera (English), Dan Osorio (Latin American Spanish)

A former Megalo Boxer turned security guard for a seedy pawn shop.

  • Decomposite Character: He is Nishi without the Character Development, as his role as the third member of the group is taken by Sachio.
  • Expy: Of Nishi from Ashita No Joe, taking a similar appereance. However, his role as the third member of the group is taken by Sachio, avoiding a change of heart in his character.
  • Mighty Glacier: His gear packs a devastating punch, especially due to not being subject to official Megalo Box regulations allowing it to have metal gloves. The downside is that the engine takes time to wind up for each punch, allowing Joe to notice which side is spinning up and easily dodge and counter.
  • Unskilled, but Strong: His Gear isn't limited by regulation standards and hits harder than anything in a ring, but his technique and footwork are practically non-existent.
  • Would Hurt a Child: Applies the Jack Bauer Interrogation Technique to Sachio after he steals the Shirato prototype Gear.

How well does it match the trope?
