Given the bad luck powers, Ilyana would be a *perfect* Himewari in the X-men version of Tsubasa/XXX (I haven't figured out who she'd be in the Avengers version, though like I said, if Wanda was the Dimension Witch, Billy and Teddy would be a cute Watanuki and Doumeki).

edit: And Kurogane would be Wolverine.
