Real Name- Madelyen Pryor-Summers
Relatives- Alex Summers(Husband), Scott Charles Summers(Son).
History- Not much is known about the mutant known as Marvel Woman. She first surfaced several years ago, approximatley 14 months before the Inferno event. Her remarkable resemblence to the deceased X-Man, Jean Grey(Ariel), has lead to some speculation that she is Grey's twin sister, or some other blood relation. However, investigations into the Grey family have produced no evidence to confirm this. There has been some conjecture that Pryor-Summers is a clone of Jean Grey, but this, too, is nothing more than a theory.
What is known is that Alex Summers encountered Madelyne Pryor on a trip to Alaska, where he was inspecting the house he had recently inherited from his late grandmother. Struck by the uncanny physical similarity between Pryor and his late teammate (and girlfriend)the two struck a friendship, which grew into a romance when she returned with him to X-Factor. Although she had no real powers at the time, Pryor was quickly accepted into their "family". She and Havok were soon married, and she gave birth to their son, Scott.
The Inferno Event, however, changed the course of the Summers' lives when Scott was abducted by the demons S'ym and N'Astirh. X-Factor, now called The Six, fought alongside Magneto's X-Men to defeat the demons, but it appears that Madelyne was key to the mutants' success. There is evidence to indicate that she struck a deal with the demons that not only saved her son--and the planet--but brought forth her previously unseen mutant power of telekinesis(yet another similarity to Grey).
Now, calling herself Marvel Woman, Madelyne Pryor-Summers acts as a co-leader of The Six.
POWERS- Marvel Woman has the power to telekinetically lift, move and-- to some extent--reshape objects through sheer force of will. The limits of her powers have yet to be tested, and it remains to be seen what, if any, further changes have occured in her abilities or personality in the wake of the Inferno Event.
