Design your own One Punch Man hero or villain in seconds with AI. Free, fast, and unlimited.

New heroes, villains, and Dragon-level threats hit the feed every day.







A One Punch Man OC is your own original hero, villain, or monster for the One Punch Man universe — a world of professional heroes, absurd threats, and one bald man who ends every fight in a single hit. Describe your character and the One Punch Man OC Maker generates them in about two seconds.
Both. Saitama, Genos, Tatsumaki, King, Mumen Rider, and Garou show up in the feed constantly. But the Hero Association is always recruiting — an original C-Class underdog or S-Class powerhouse is where the fun is.
Either works. Heroes slot into the Association's C, B, A, and S ranks — decide where yours sits and let the design show it. Monsters scale by threat level, from Wolf and Tiger up to Demon and Dragon. A great gag OC is a terrifying design with a C-Class rank, or the reverse.
Prompt for clean modern anime linework, and spend the detail where the series does: hyper-detailed monsters, machines, and destruction against simpler hero designs. A plain, almost boring costume on an obviously overpowered character is the most One Punch Man design there is.
Yes. Every generation is free — no credits, no watermarks, no daily caps. Fill out the whole hero registry if you want.
Yes. Every creation can be shared to the feed, and anything on the feed can be remixed — a rank-up, a battle-damaged version, a monster form. Remixing is the heart of GenTube.
One gimmick, pushed to an extreme. The series' best characters are a single idea taken completely seriously — a cyborg, a bicyclist, an esper in a black dress. Make the power readable from the costume alone.
Of course. It's your original character — use it as a profile picture, in your fan stories, or anywhere else. You can also roleplay with your characters in GenChat.
