Frequently asked questions

An MHA quirk generator is a fan-made tool that creates original superpowers — quirks — in the style of My Hero Academia. Each result gives you a quirk name, its type (Emitter, Transformation or Mutant), how it works, a drawback, an ultimate move, power stats and a hero name idea for your original character (OC).

No. Every quirk in our bank is an original fan creation written for this site. They follow the rules of the series — the three quirk types and the golden rule that every power has a real cost — but none of them are copied from the manga or anime.

Emitter quirks project substances or energy from the body, or affect the world around the user. Transformation quirks temporarily change the user's body when activated. Mutant quirks are permanent physical traits the user is born with and cannot switch off. Some rare quirks also need to stockpile energy before they can be used.

A believable power with a real cost. That is the golden rule of My Hero Academia: every strong quirk carries a drawback — overheating, recoil, stamina drain, sensory overload — plus clear activation rules and limits a rival can play against. Balance is what makes a quirk interesting to write and fair to roleplay, so every quirk in our bank ships with a drawback and stats you can compare at a glance.

Yes. Anything you generate here is free to use for your original characters, fanfiction, roleplay and art. Rename it, tune the stats, evolve it — make it yours. Credit is appreciated but never required.

No. This is an unofficial fan project made by fans, for fans. It is not affiliated with or endorsed by Kohei Horikoshi, Shueisha, Bones or Toho. My Hero Academia and all related names are trademarks of their respective owners.

Yes — completely free, with no sign-up and no limits. The generator runs entirely in your browser, and the full quirk bank is published on the Quirk Ideas page so you can browse every quirk without generating at all.

It rolls from a hand-written bank of original quirks — no AI text generated on the fly. Your filters (type, alignment and role) narrow the bank first, then one quirk is picked at random from what matches, avoiding an immediate repeat of your last roll.

Every quirk's four stats — Power, Speed, Range and Control — add up to a total out of 40. We rate that total as a class: S (30+), A (25–29), B (20–24), C (15–19) or D (under 15). A high class means a stronger overall quirk, but class D quirks with clever drawbacks are often the most fun to write.

Each quirk in the bank is tagged with the hero work it suits: Combat, Rescue, Support, Stealth or Defense. Pick a role when you already know your character's job — a Rescue roll, for example, will only return quirks built for saving people rather than fighting.

Yes. Use the 'Roll 3 & pick' button: you get three different quirks side by side, with their type, class and a short description, and you click the one you want to load in full. Your recent rolls also stay under the generator, so you can go back to one you skipped.

We love reader quirks. Send your idea through the contact page with a name, type, how it works and — most important — its drawback. If it follows the rules of the series, it may join the bank in a future update with credit to you.
