Marrow

Hideously deformed by her mutant ability of accelerated bone growth, Marrow was one of the underground-dwelling Morlocks. When the mutant-hunting Sentinels led by Bastion activated Opeartion: Zero Tolerance, Marrow found herself aligned with the Uncanny X-Men, whose ranks she joined. While with the X-Men, Marrow learned how to better control her powers, preventing bones from growing out of her face, giving her a more conventional appearance.

Marrow was amongst the 99.9% of mutants who were de-powered by the Scarlet Witch after the events of M-Day.
