When a fighter is born, it is at Level 1, with three starting random SuperPowers. By battling in matches and participating in other active activities, fighters earn EXP and level up. Fighters unlock their hidden potential as they level up: additional SuperPowers are revealed at levels 5,10,15 and 20. In between of these significant levels, fighters may also unlock mystery boxes or some specific items, like $ZENY or a cosmetic item, exclusive to fighter's race. This is very similar to the concept of battle passes, popularized by Dota2. Maximum level cap is 40, but after level 20, no more rewards are given for levelling up and no more superpowers are unlocked.
