History
Witch joined the inter-dimensional superhero team (The Exiles) while trying to resurrect her brother but was killed by Emma Frost in action, and was replaced - without the knowledge of her teammates - by yet another alternate version of herself.[1]
Trivia
When she met the Wanda Maximoff from Earth-90631 she commented how that Wanda needed to lose some weight and questioned why her costume was so "slutty". This however was pretty ironic considering that she seemed to be wearing exactly the same outfit as her counterpart only with cape.
