“A woman whose touch steals — unable to hold anyone close, she turned loneliness into strength and became the heart of the X-Men.”
Drains powers, memories, and personality through skin contact. Longer contact means longer-lasting effects. She cannot turn it off.
In a key comics arc, she absorbed Ms. Marvel's abilities so long they became semi-permanent — giving her flight and super-strength.
A solitary warrior carrying fragments of other people's memories in her head. The inability to touch anyone has become her defining identity — channeled alternately into anger and into deep empathy. Her pivot from villain to hero came when the X-Men were the first to accept her as she was, and since then she's been the team's emotional compass.
