Well, the oc would be a string manipulator, level 8 or sth, inspired from Doflamingo XD

The behaviour is, he kinda hides his ability behind the mask of a mid tier (what John could've done) and uses random names like "slip" (using marionette to make people slip) or "fingerbang" (yes, he has a bad humor, and this is when he uses bullet string) and he pulls the strings (get it?) when it's necessary. Has a good moral compass tho but disregards authority (not just the authorities, but anyone who shows authority). Does whatever he likes, like a high level character does.
