Marrow (character)

Marrow (Sarah) is a character appearing in American comic books published by Marvel Comics. Created by writer Jeph Loeb and artist David Brewer, the character first appeared in Cable #15 (September 1994). Marrow belongs to the subspecies of humans called mutants who are born with superhuman abilities. Marrow is able to rapidly grow and protrude her bones, which she can use as armor and weapons. As a child, Sarah was taken in by the Morlocks, a band of grotesque-looking mutants who hid in tunnels beneath New York City. As a young adult, she formed the violent splinter cell Gene Nation until, under the orders of Morlock leader Callisto, she joined the X-Men to redeem herself. She made progress controlling her powers and learning a moral code, but eventually fell in with the paramilitary group Weapon X.
