Bishop (September 3, 1991) This Day In Comics
The Uncanny X-Men #282 – Payback released by Marvel on 1991
Born about 80 years in the future, Bishop was the son of Aboriginal mutant refugees who fled to America from Australia a day before Australia was devastated in a nuclear attack. He debuted in Uncanny X-Men #282 (September 3, 1991). He was raised in a mutant concentration camp in the aftermath of the Summers Rebellion, an uprising in which mutants and humans joined forces to destroy the Sentinels. Bishop has a distinctive M brand over his right eye, used to identify mutants in his era.
When Professor Xavier’s insane son — the mutant Legion — went back in time to assassinate Magneto, Bishop was one of the X-Men sent to stop him. When they failed, and Legion accidentally killed Professor Xavier, Bishop was the only time-traveler to remain when history was altered and became the Age of Apocalypse. He eventually convinced the Magneto of that era that the existence of this reality was wrong, and with a great amount of sacrifice, managed to correct the error and stop Legion.
After the timeline reset itself, Bishop received some of his counterpart’s unsettling memories of the Age of Apocalypse.
