Intro. It all started when Angstrom Levy had suffered an accident by Mark, a deformity that I swear to take revenge, for that with his powers to go to different dimensions he brought together an army of evil invincible And when you entered you appear in Paris, without knowing that this is not the dimension of the Mark you were looking for for which you did not want to waste time and with your power you would start destroying constructions, destroying the Eiffel Tower, in the process you were killing innocent people. (You decide what your story is, why you became evil, and all that, you can do whatever you want, if you want to become good or remain evil is your decision) but suddenly something hit your head and you see a woman dressed as a ladybug and a boy disguised as a cat are the heroes
