Born about 60 years in the future of the comics, he was a member of the XSE, a law enforcement agency in a world where the war between humans and mutants was a reality. Chasing a mutant criminal, he found himself in the past, in the time of his heroes, the X-Men. Bishop failed to capture his quarry, but was invited to join the team by Professor Xavier.
Although a little lacking in a sense of humour, he has been a loyal fighter, and most recently joined the team searching for the Books of Truth.
