Marrow

Marrow, whose real name is known only as Sarah, is an X-Men villain who was once an X-Man for a time. She can pull extra bones from her body to be used mostly as melee weapons.

This mini, formerly an Old Republic Recruit from the LotF set, depicts her time when she was an agent of Weapon X, under Director Malcolm Colcord. He helped her control the bone growths that gave her a disfiguring appearance. Marrow became an attractive young woman from this, but her meanstreak remained unchanged.
