Illyana Rasputin (Earth-2326)

"I know a demon when I see one. Sooner or later every man shows himself."

- Magik

Illyana Rasputin was a young Russian farm girl whose mutation allowed her to channel energy from Mephisto's Realm (otherwise known as Limbo) to perform sorcery. This caught the attention of Weapon X, who sent Wolverine after her. Although her older brother, Piotr, defended her, she ultimately lost the fight as Wolverine chopped off her arm and took her to Weapon X, where they gave her an Adamantium replacement and used her powers to conduct dealings with Mephisto. She was eventually rescued by the X-Men, who she would come to consider her family.

Trivia

 * Limbo is the realm that Nightcrawler subconsciously travels through when he teleports, due to his father, Azazel's connection to Mephisto.
 * Although the two are very close friends, Illyana has a crush on Kitty Pryde.
 * Illyana claimed the Soulsword at the age of 10 when she defeated one of Mephisto's champions who had previously wielded it.
