SPECIAL ABILITIES: Rapidly re-grow the protruding bone spurs that protrude from her body, and which she uses as weapons. She also possesses two hearts and enhanced durability, making her difficult to kill.
BACKGROUND: She was a young mutant who left her normal life behind to journey into the sewers controlled by the Morlocks. Marrow survived the Mutant Massacre, which killed nearly all of them. After a number of encounters with the X-Men, Marrow joined with the group. However, her fiery personality and natural savageness meant that she never fit in at Charles Xavier’s school, and she left under mysterious conditions. More recently, she was recruited by the newly formed Weapon X program, who have boosted her mutant powers so she has control over her appearance.
