However, a clandestine faction of XSE agents called the Xavier's Underground Enforcers (XUE) uncovered his true power: the ability to travel through time.

The XUE recruited Shard and orchestrated Fitzroy's release, intending to exploit his temporal abilities to alter the past and create a better future.

The prisoners attacked the X-Men but stopped when three figures stepped through the portal: Bishop and XSE agents Randall and Malcolm.

When the Gamesmaster declared that the new target for the Upstart competition would be former members of the New Mutants and Hellions, Fitzroy attacked X-Force, demanding they turn over Rictor and Warpath.

How he survived is left unknown, but Fitzroy eventually reappeared under the thrall of Selene as the White Rook of the Hellfire Club.

After Cortex kills him during a fight, Layla Miller resurrects him physically but is unable to revive him with a soul, establishing the point at which he becomes a villain.

He helped kill the Nasty Boys in order to lure out Cyclops and his ragtag team of X-Men to Washington Heights.

Fitzroy can also use the converted life force he drains to infuse on the dead, which essentially resurrects them; however, due to his nature, this is an ability he rarely uses.

[5] In his early appearances, Fitzroy wears a futuristic battle armor that increases his strength and protects him from opponents.

[6] Trevor Fitzroy appears in the X-Men: The Animated Series two-part episode "One Man's Worth", voiced by an uncredited actor.

Toy Biz produced an action figure of Trevor Fitzroy in 1994 as part of the fourth X-Men wave.
