Sarah Knuckey is a fictional 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).[3] Knuckey belongs to the subspecies of humans called mutants who are born with superhuman abilities.[4] She is known under the codename Marrow.[5] She is able to make her bones grow out of her skin.[6] These can be removed from her body, providing her with potential knives, clubs, and body armor.[7]
As a child, Knuckey 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.
