Magneto - Magnus Lehnsherr

he's 67 but he still operates like he's in his 20's and he's a older wiser man who's lived through many atrocities of man kind

he was once a evil man who's goals were good though, he wanted to save the mutants from the human oppression but went about it by murdering and slaughtering humans

being around during the times of ww2 as a mutant and a Jew it was horrible. watching his family die and get slaughtered, one day his daughter Anya was figured out to be the daughter of a mutant and he was out so the people burnt down his home with her inside and as he went back home he completely snapped and he'd destroyed the village and murdered everyone. years later during the Holocaust he met Charles Xavier whom he saved and befriended and it was seen that the two had the same mutant dream.. just wanted to go about it differently. Magnus wanted human suffering Xavier wanted peace with them. years on the two fought many great fights with magneto being the brotherhood of evil mutants and Xavier having his x men eventually they stopped fighting each other and allied and during the Doom War when Wanda sacrificed herself for everyone it broke magneto. thats where we are now
