Build a fighter the legends have never faced
Free for every WhoWinsAI member. Your character, your rules, the same engine that decides every battle on the site.
The Creator Studio lets you design an original fighter from scratch: a name, a look, a power level, the powers that make them dangerous and the weaknesses that keep them honest. Then you send them into a test fight against any of the 780+ characters on WhoWinsAI — Batman, Goku, Superman, Thanos, Sukuna — and the battle engine tells you exactly who wins and why.
There are no dice and no votes. The same rules that settle every matchup on the site settle yours, so a clever build beats a big number. Every result comes with the reasons: which power landed, which defence held, and who could actually end the fight.
Four divisions, Street to Cosmic
Each division has its own points budget, set by testing builds against the real characters at that level.
Street
Fighters, vigilantes, monsters of the alley. Bullets and fists.
90 pointsCity
Buildings fall. Cars get thrown. A city block is the arena.
140 pointsPlanet
Continents crack. A world is what is at stake.
170 pointsCosmic
Stars and galaxies. The top of the scale is kept for canon.
220 pointsFrom idea to verdict
It takes a few minutes. Tweaking it can take all night.
- Assemble. Pick a division and spend your points: power level, durability, intellect and up to ten abilities, from energy blasts and regeneration to sealing and time stops. Take on a weakness to win points back.
- Test. Choose any canon opponent and a setting — a random encounter, morals off, or time to prepare — and run the fight. Test fights are private and never touch the rankings.
- Compete. Share your fighter in the gallery and enter the Creators’ League, where it fights every other entry in its division and climbs an Elo table.
Why you cannot just max everything
The budget is the game.
Every power has been played through the engine to measure what it really adds, and none costs less than the wins it buys. The very top powers — erasing concepts, destruction that ignores durability, rewriting reality, near-unkillable anchors — are signature powers: one per character, never two. Weaknesses only pay points back when fighters in your division can actually exploit them.
We tested the budgets by hunting for the strongest build possible in each division. The best one we could find ranks around third against the canon characters of its level — strong, but never the best. Read all the rules.
Your first fighter is a few minutes away
Joining is free. You can build up to ten characters and test them as often as you like.
