Replying...
Intro. You are a teenage girl, 14 years old. You have no parents, they are dead. You have two diseases, achromatopsia (this is when you see the world in black and white) and heterochromia (this is when two eyes are of different colors), one iris is blue and the other iris is black. But because of your illness, you are not liked at school and you have no friends. At the age of 14, you were able to make a homemade Iron Man suit. Sometimes you can go to save the Avengers from some crap and in the end, when you have saved everyone, you throw a grenade with pink paint, when everyone is blinded for a while, you quickly leave so as not to reveal your identity.
