The future Trevor Fitzroy is the illegitimate son of Anthony Shaw, the future Black King of the
Hellfire Club, in a dystopian future. He joins the Academy for
Xavier's Security Enforcers (XSE) and has a romantic relationship with
Shard. However, Fitzroy's criminal tendencies surface, resulting in his expulsion from the academy. Initially, his influential father attempts to shield him, but when Fitzroy is apprehended for murder, his father could no longer protect him.
Bishop (Shard's brother and an XSE officer) captures Fitzroy. Initially, Fitzroy believed that he possessed the ability to teleport. However, a clandestine faction of XSE agents called the Xavier's Underground Enforcers (XUE) uncover his true power of time travel. The XUE recruit Shard and orchestrate Fitzroy's release, intending to exploit his temporal abilities to alter the past and create a better future. Shard, recognizing Fitzroy's inherent danger, intervened and thwarted their plan, resulting in Fitzroy's return to prison.
The Upstarts From prison, Fitzroy escaped to the present time with his mutant minion
Bantam. There, he became involved with a group known as the
Upstarts, a competition set up by
Selene to eliminate her rivals in the Hellfire Club. Fitzroy attacks
X-Force, demanding they turn over
Rictor and
Warpath. In the ensuing confrontation,
Cable tricks Fitzroy by disguising his techno-organic arm as wholly organic. When Fitzroy attempts to absorb Cable's energy through the arm, his powers backfire and cause him to use his own life energy to open a portal, seemingly killing him.
After the Upstarts Fitzroy eventually reappears under the thrall of Selene as the White Rook of the Hellfire Club. During this time, he cooperates with Pierce and Shaw, despite his previous attempts to kill them. He leaves the club and travels back to an alternate future (Earth-9910), now calling himself the
Chronomancer. He takes control of the new timeline, but Bishop arrives and fights Fitzroy, eventually killing him.
X-Factor A younger, benevolent version of Fitzroy appears as a participant in the Summers Rebellion. After Cortex kills Fitzroy during a fight,
Layla Miller resurrects him. She is unable to restore Fitzroy's soul, establishing the point at which he becomes a villain. ==Powers and abilities==
