X-Man
In the alternate reality called "Age of Apocalypse," the native version of Sinister uses DNA from Jean Grey and Scott Summers to create a powerful mutant called Nate Grey. After Nate transports to the mainstream Marvel reality and makes a home there, Sinister's agent Threnody befriends him. When she refuses to work for Sinister further, he sends the Marauders and they battle Nate Grey. Using his telepathy, Nate causes Arclight to kill Blockbuster, then manipulates Riptide to kill Arclight. It is soon after this that Gambit discovers Sinister keeps clones of all the Marauders, ready in the event of their deaths. He rarely attempts to clone Sabretooth, whose healing abilities and feral nature make even his clones resistant to mental control.
