Marrow (Yost Universe)

Marrow is a member of the in the future.

History
Marrow developed mutant powers. She was captured by the and taken prisoner as a result. There, she met after he awoke from a twenty year coma. He used his abilities to stop some interference from a official, which baffled Marrow and caused her to bombard him with questions. They ranged from where he was hiding, what his powers were and even how he knew her name after she questioned him initially. She heard of his plans to reach the X-Men in the past, which she did not look on as a faithful course of action. She also dismissed that he was the real Charles, though this was proven false once he used his powers to talk to her telepathically. The Sentinels had taken from him and could use it to locate every single mutant and prevent them from hiding ever again. Learning of this, Marrow chastised Charles for brining a "mutant tracker" into their already bad predicament and questioned why he did not just destroy the device when he had the chance.

Though Charles tried to justify not destroying it by explaining it was his only link to the past, Marrow gave little admiration for his words. She angrily told him to stop worrying about the past, and focus on the present and also claimed he had made everything worse before storming off.
