History
Dia was a young mutant who approached Jessica Jones for help. Her boyfriend was intensely jealous of her mutant abilities and so she had granted them to him. He used them on himself to split himself into two, one was charming whilst the other was a monster.
The dark twin went on a murder spree forcing Dia to reverse all of his actions and merging the two back together again. He was then arrested, without his granted powers, by the police.
Powers
Dia is an exceptionally powerful reality-warping mutant with the ability to shape-shift, fly, and craft buildings out of thin air. She rarely demonstrates this in the Prime Universe, but in alternative universes, she’s a terror.
