Ev Teel Urizen is a fictional character in the Marvel Universe. It was created by writer Mike Carey. Ev Teel Urizen first appeared in X-Men #197 (May 2007).
Ev Teel Urizen is a mummudrai, a mental parasite constructed of energy latices that exists on the astral plane. Mummudrai are "born" with every living being in the womb. In Shi'ar legend, they are described as the a living being's first contact with the idea of "the other". While many die in the womb, some choose to remain in the host's mind, harmless and dormant. This was the case with Urizen, who stayed harmlessly with its host Ul'var Urizen.
Urizen fled from the edge of Shi'ar space following a trail of psychic energy to the X-Men's Mansion, seeking help from the X-Men's powerful psychics to stop Hecatomb before "he" (as Urizen refers to it) consumed everything.
Like all mummudrai, Ev Teel Urizen possesses the powers of telekinesis and telepathy and can inhabit and possess nearly anyone by performing jumps on the astral plane.
