Scrambler

The mutant sociopath Scrambler is a member of the Marauders, a band of assassins who were gathered together by the mutant thief Gambit at the request of the enigmatic mastermind known as Mister Sinister.

Sinister first sent the Marauders to murder the entire population of the underground mutant community known as the Morlocks. In the course of this mutant massacre, the Marauders clashed with the mutant adventurers known as the X-Men and the original X-Factor team. Subsequently, the X-Men thwarted the Marauders' attempt to assassinate Sinister's former pawn, Madelyne Pryor, in San Francisco.

Later, Sinister sent the Marauders to battle the X-Men during the time of the demonic invasion of New York City known as the Inferno. The Marauders were all killed, but Sinister possesses samples of their DNA with which to clone them.

The Marauders later clashed with the dimensionally-displaced young mutant known as Nate Grey after they attempted to assassinate Sinister's former servant, Threnody; Scrambler was killed in Nate Grey's power burst.

Scrambler retained his mutant powers after the M-Day and returned once again as a member of the New Marauders, alongside old-time members such as Scalphunter and newer members Sunfire and Exodus.

Scrambler was killed by X-23 in an attempt to free the new-born mutant messiah from the Marauders.
