Mickey Tork was originally the San Franciscan vigilante known as Rainbow before his mutant powers evolved, granting him the chameleon-like ability to blend in with his surroundings. Bloke came to the attention of the Coach, manager of the new media savvy X-Force team, after a successful mission against a Balkan terrorist group, and he was recruited into the team following the death of several members in the botched rescue attempt of popular musical group Boyz R Us.
An openly homosexual hero, Bloke was killed during his first mission with X-Force in the Republic of Bastrona as he tried to shield the team's Bastronan informant from missiles fired by gunships of the Bastronan Army.
