Mystiq

Mystiq is a male counterpart of Mystique from Earth-797, here named Raphael-Raven Darkholme. He and Destiny were married, and had a child. Both Destiny and the child were killed.

Sabretooth of the Exiles accidentally ended up in this reality, and saved him from an assault, and after that Mystiq apparently joined the Exiles.

In a mission to Earth-6706, alongside his fellow Exiles (Sabretooth, Psylocke and Rogue), assumed the form of that earth's Susan Storm, whom was the wife of Namor, in order to save her life. When the Black Panther(rather T'Challa's evil cousin who killed him and siezed the throne) takes Susan, who is really Mystiq, hostage she shredds his throat. Following the insueing battle which lasted only a few minutes, Mystiq is found to have recovered from his fatal injury without the help of anyone else. He reveals that he is "very hard to kill". Which suggest that he may have an enhanced healing factor having recovered from a injury that fatal so quickly. He is also seen taking care of an injuried Susan Storm and Psylocke which hints to some medical knowlege.
