History
This Raze Darkhölme's life followed the same path of his Earth-13729 counterpart's, up to the point he convinced his half-brother Charles Xavier II that the Brotherhood should go back in time, and defeat the X-Men before they had mastered magic and tech. Prior to departing from their timeline, however, the Brotherhood received a letter from Earth-13729's Raze, who had already traveled to the past alongside his team. It contained instructions in how to try again and win.[2]
Raze was one of the Brotherhood members who were sent back in time to replace their lost counterparts among the team's ranks in the past,[1] as his counterpart had been removed from reality by a Phoenix variant sometime after writing and sending the letter.[3][2] He impersonated X-23 in order to infiltrate the New Charles Xavier School and get rid of the X-Men's healer, Triage.[1] In the confusion that ensued, the Brotherhood attempted to eliminate the time-displaced Jean Grey, but they failed and Xavier lost control over the mind-controlled members of the team. Raze and his brother were subsequently left under the care of S.H.I.E.L.D. while the rest of the Brotherhood was sent back to the future.[4]
