The short answer, because you came here for it: Untitled Boxing Game is based on Hajime no Ippo — the boxing manga and anime formally known as Fighting Spirit in the West. Every fighting style in the game with a confirmed inspiration comes from that one series, the game's own Roblox page carries the anime tag, and the community wikis document the mappings character by character. The long answer — which this page exists for — is a trail of references that runs far deeper than the base roster: ultimate animations that homage Chainsaw Man, upcoming shinies pulled from JoJo and Yakuza and Street Fighter, and glove sets named after Devil May Cry weapons. Everything below is sorted into what's verified and what's still just community talk, because half the fun of a reference guide is knowing which half to believe.
The Core: Hajime no Ippo
Six styles in Untitled Boxing Game have documented, wiki-confirmed character inspirations — and all six come from Hajime no Ippo, George Morikawa's long-running manga about a shy high schooler who becomes a professional boxer. That's not a coincidence; it's the design thesis. The manga is beloved precisely for turning real boxing technique into character identity — every rival fights like a distinct school of boxing — and the game lifts that grammar directly:
| Style | Based on | Who they are |
|---|---|---|
| Ippo | Makunouchi Ippo | The protagonist — peek-a-boo guard, infighting, the Dempsey Roll |
| Hawk | Bryan Hawk | The wild, arrogant champion — unorthodox, vicious counter machine |
| Wolf | Alexander Volg Zangief | The technical outboxer — White Fang precision from range |
| Bullet | Sawamura Ryuhei | The dirty-talented rival — flicker jabs and rule-breaking instinct |
| Freedom | Wally | The natural genius — wild footwork, three modes of unlearnable chaos |
| Surgeon | Kazuki Sanada | The tactician-doctor — clinical, target-precise pressure |
What makes the mappings worth knowing — rather than trivia — is how literally the game translates each character's identity into mechanics:
Ippo is the manga's earnest student, and his style plays like it: peek-a-boo guard swaying side to side, damage built through patient infighting, the Dempsey Roll as the payoff. Hawk carries the character's contempt for the sport into the kit — the documented 1.6x counter multiplier rewards the arrogance of punching into someone else's attack, and Swayback (a perfect dodge performed standing still) is pure Bryan Hawk showmanship. Wolf translates Volg's precision: heavy punches that always come from the same documented side, the White Fang as a signature from range, an ultimate that restages his max finishing blow.
Bullet keeps Sawamura's rule-breaking streak — the style's ultimate literally opens with a headbutt, illegal in the sport both the manga and the game otherwise imitate. Freedom is Wally's wildness made mechanical: three fighting modes swapped on the fly, fragile at 80 HP but impossible to pin down, exactly the natural-talent chaos Wally brought to the ring. Surgeon is Sanada's clinical mind: Pinpoint damage driven into specific body regions, debuffs stacking like a chart at the foot of a hospital bed, an ultimate called Medical Malpractice that injects a vision-dulling sedative. Read the styles index with this table open and the pattern is obvious: choosing a style in Untitled Boxing Game is choosing a character archetype from the manga. Ippo mains and Hawk mains are playing out the same personality clash Ippo and Bryan Hawk fought out on the page, one copied ultimate at a time.
The Ultimate Homages Go Beyond Ippo
The style inspirations stay inside Hajime no Ippo, but the ultimate animations — the game's biggest stage — branch out:
- Ippo's Tiger Crusher restages the Ippo vs. Sendo featherweight title ending: feint jab, Gazelle Punch, Dempsey Roll, heavy finisher. It's a faithful reproduction of a specific fight, not a generic flurry.
- Wolf's True White Fang is Volg's max finishing blow, down to the reversed, slower windup that old Wolf players learn to read.
- Hawk's Pure Violence is the outlier: its theme is the Chainsaw Man Volume 12 PV — six head shots and a low-stance driving right that belongs to a completely different manga's energy. Hawk the character is from Ippo; Hawk's ultimate cinematography is Fujimoto.
One boxing-history footnote the wiki preserves: the Dempsey Roll isn't a Hajime no Ippo invention even in the manga — the technique is named for Jack Dempsey, the historical heavyweight who created it. The game's references stack: an anime referencing boxing history, referenced by a Roblox game.
A note for Western readers hunting the source material: Hajime no Ippo was released in English as Fighting Spirit, and its anime adaptation runs over a hundred episodes covering the early arcs — the Ippo vs. Sendo fight that Tiger Crusher restages is among its most famous sequences. If a move in Untitled Boxing Game feels like it carries weight beyond its damage number, the manga panel it came from is usually the reason.
The Shiny Universe: Anime Without Borders
If the base roster is a Hajime no Ippo tribute, the shiny styles — reskinned fighters with outfits and animations mimicking other characters — are where Untitled Boxing Game lets its taste run across all of anime and gaming. The community wiki's roadmap of confirmed and teased shinies reads like a crossover episode:
- Star Platinum (JoJo's Bizarre Adventure) — confirmed as the Shotgun shiny
- Gon Freecss (Hunter x Hunter) — confirmed by community poll, with an ultimate animated after Gon vs. Pitou
- Reigen Arataka (Mob Psycho 100) — the Conman shiny, teased by the developer
- Kiryu Kazuma (Yakuza) — triple-teased, strongly implied for Freedom
- Akuma (Street Fighter) and Alucard (Castlevania or Hellsing — even the wiki hedges) — confirmed by poll, roles unknown
- Plus Doctor House — yes, the American medical drama itself, cane idle animation and all
A honest caveat the wiki itself attaches: these are upcoming or teased, several on records more than a year old, and some (Gon's tie to Ranked V2) are community inference rather than developer announcements. The current shiny roster is smaller — five live shinies at the community wiki's last count, with each new addition raising the drop rates for everything below it — and the full mapping lives in the game itself. But as a statement of what the game wants to be, the roadmap is unambiguous: a boxing museum with exhibits from everywhere, and the front desk doesn't check passports.
The Gloves: Devil May Cry and Ultrakill
The cosmetics carry their own references. The three most storied glove families — Beowulf, Balrog, and Gilgamesh — are all named and designed after Devil May Cry weapons (Gilgamesh from DMC4, Balrog from DMC5, Beowulf from the series at large). The rarest trophy gloves in the game are, functionally, a Devil May Cry tribute wall.
Going deeper still: the upcoming style-gloves system — rewards for mastering every title within one style — has already showcased two designs based on V1's arms from Ultrakill, the indie shooter. A boxing game wearing a boomer-shooter's prosthetics is exactly the reference stacking this page keeps finding.
What's NOT Verified (The Honest Column)
A reference guide that only lists confirmations teaches you to trust everything you hear. So, the other column:
- Ghost's inspiration: no credible source. The community loves to guess — the game is clearly Ippo-adjacent, so the guesses run Ippo-ward — but no wiki documents which character, if any, Ghost is based on. Any page that tells you confidently who Ghost is "from" is making it up.
- Chronos: no public record at all. Both community wiki pages for Chronos are empty. Its prototype, name, and inspiration are simply undocumented.
- Takamura, Miyata, Aoki, Volg-as-style-name and similar community terms circulate as nicknames or hoped-for future styles — the names players reach for when guessing what comes next, because they're the manga's beloved bench. They are not verified mappings to anything in the game today. Hajime no Ippo has dozens of memorable fighters; Untitled Boxing Game has so far imported six of them, with receipts, and this page will say so until the seventh arrives with one.
FAQ
What anime is Untitled Boxing Game based on?Hajime no Ippo (released in the West as Fighting Spirit). All six styles with documented inspirations map to characters from that series, and the game's official Roblox page carries the anime tag.
What anime is Hawk from?Bryan Hawk, the wild champion from Hajime no Ippo. One wrinkle: his ultimate's animation theme is Chainsaw Man's Volume 12 PV, so the character is Ippo-universe but the ult's cinematography isn't.
Is Ghost from an anime?No verified source says so. Community speculation connects Ghost to the Ippo universe, but no wiki documents an inspiration for the style — treat any confident claim about Ghost's origin as unverified until a source appears.
Are the shiny styles from anime?Partly, and increasingly so: confirmed and teased shinies reference JoJo, Hunter x Hunter, Mob Psycho 100, Yakuza, Street Fighter, and even House M.D. Several are upcoming rather than live — check the shiny roadmap's own timestamps before treating any one as current.
Why does the game reference boxing history too?Because its source material does. The Dempsey Roll used by the Ippo style is named for Jack Dempsey, the real historical champion who created the technique — the manga cites him, and the game inherits the citation.
Where do the shiny and glove references come from?Everywhere: JoJo, Hunter x Hunter, Mob Psycho 100, Yakuza, Street Fighter, House M.D., Devil May Cry, Ultrakill. The base roster is strictly Hajime no Ippo, but the cosmetics and shinies treat the whole of anime and gaming as fair game — the sections above carry the full verified list.
Every verified mapping above is documented on the community wikis (style pages, shiny roadmap, gloves catalog), cross-checked against the official Roblox game page, August 2026. New styles and shinies keep arriving — re-verified monthly.
