MHA Quirk Generator — A Quirk, a Drawback, a Student
Most generators stop at a word. This one gives you a sheet and the student who has to carry it.
Play the U.S.J. scene.
Four minutes before the drill, a second-year transfer student is flat on his back under a vending machine. Three answers, one drawback, and it fires at T–01:16.
A quirk is a character, or it is nothing.
Neta Studio is an AI world builder. The sheet, the portrait and the scene come out of the same brief, so the student in the dialogue box is the one on the sheet — same quirk, same limit, same very bad day.
- The sheet, not a word — Name, type, one sentence of effect, the range, the limit, the drawback, and a rating out of 5 with the reason printed next to it.
- A student with a face — Hero name, year, one line of personality and a portrait in the world's own style, kept consistent when they walk into the scene.
- A scene that tests it — Three choices in a dialogue box, and one branch where the quirk fails at exactly the wrong moment. That is where a drawback stops being flavour text.
Questions? Answered.
Is this the official My Hero Academia quirk generator?
No. It is a fan tool built on Neta Studio, not affiliated with Kohei Horikoshi or Shueisha. The quirks it writes are original.
Do I need to know MHA to use it?
No. Say what the person is like and what you want the power to do, and the sheet handles the rest. Fans get the canon vocabulary — Emitter, Transformation, Mutant, hero names, U.A. years.
What do the three quirk types mean?
Emitter sends something out or bends the world at range. Transformation changes the user's body while it is active. Mutant is a body permanently built differently. The sheet picks one and stays with it.
Why does every quirk need a drawback?
A power with no cost cannot lose, and a character who cannot lose has no scene. The drawback is the thing the scene tests.
Can I choose the quirk instead of rolling one?
Yes. Describe it in the box — "a quirk that turns noise into weight" — and the sheet is written around your idea, drawback included.
Can I use the quirk for an OC, a fic or a roleplay?
That is what it is for. The student is added to the world as a character, so you can keep playing them, drop them into other scenes, or write them out.
Does it work outside MHA?
The same brief has been run in a Hunter x Hunter world and a One Piece world — a nen ability with a condition, a Devil Fruit with the sea as its bill. The vocabulary changes; the sheet does not.
Can I play the scene after it is built?
Yes. The scene publishes as a link that opens in a browser, and the playable proof on this page is a real one.
Roll a quirk someone has to survive.
One line in. A sheet, a student and a playable scene out.
