First Appearance: Cable #15 - 1994 Like most good heroines, mutant women tend to be pretty hot. They don't get much more freaky than white hair and zero percent body fat. The horror. So you could imagine how crazy the addition of a chick with bones popping out of her body was. And she had pink hair! Only known as Sarah, Marrow was a homeless member of the sewer-dwelling Morlocks; mutants too physically mutated to live with humanity. In her case, the physical mutation was inhuman bone growth which she could use for various weapons and armour. Depending on the artist, her passive bone protrusions could be anything from attractive and shapely armour to just random femurs jutting out everywhere. Despite this disfigurement, Marrow's bone-powers had the utility of allowing her to create anything from clubs, projectiles, and even knuckle claws like that Canadian guy. To top that off, her powers logically gave her a nigh-unbreakable skeleton and accelerated healing. This is best illustrated when Storm gutted her - long story - and it turns out that she has TWO HEARTS for just such an occasion. As you could imagine, Marrow's homelessness and horrific powers made her a bit unstable. Despite her badass-ness, she was never a consistent X-Man. One of her only claims to fame was her "BONE-MERANG" shouting portrayal in Marvel Vs Capcom 2.
