Anya was magnetos first daughter. Originally, Eric believed in human-mutant coexistance. One day, their house caught fire, and magneto was held back by the crowd, who would not let him into the house to save his young daughter (just because he was a mutant). This made Eric very mad, and he got so mad that he unleashed the full force of his powers upon the townspeople, who he blamed for Anya's death. This (as well as his experience of the holocaust) was what caused Eric to hate humans.

She was featured in the chaos engine trilogy. In it, Magneto gains possession of a cosmic cube, and he alters history so that Anya was never killed and is still alive. This means that in the new timeline he never lost faith in humanity, and creates a virtual utopia where mutants and humans live together peacefully, with eric in charge of the x-men.
However, it ends badly when Red Skull kills magneto and gets the cube for himself, changing history and altering reality so that the nazis did eventually take over the world.
