The mutant known only as Bishop was born in the 21st Century A.D. of alternate timeline Earth-1191 in which the mutant-hunting robots called the Sentinels had taken control of North America. In this timeline, Professor Charles Xavier and most of the members of the mutant team he founded, the X-Men, were killed by the Sentinels. Mutants were killed or were imprisoned within "mutant relocation camps."

Bishop and his sister Shard were both born in one of the "mutant relocation camps." Like other mutants they were branded with "M" tattoos over their right eyes for identification. Fitzroy eventually turned criminal and was imprisoned. He broke free and escaped with other mutant criminals back through a time portal to the X-Men's own time. Bishop, Malcolm, and Randall followed, even though they were aware they had no means to return to their own time. The three eventually found and killed the criminals known as the 'Lifers', but Malcolm and Randall were killed and Bishop himself was severely wounded. He was taken to the Institute to recover. During the fight that followed, Bishop defeated Fitzroy moments before he could complete his quest.

While his methods initially caused conflict with Storm, not to mention his accusations towards Gambit, Bishop joined the X-Men. He tended to act brashly, such as shooting through walls rather than using the door when an intruder alarm sounded.
