Bishop's History
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.
Eventually, "normal" human beings and mutants joined forces and overthrew the Sentinels in the "Summers Rebellion." However, "normal" humans still resisted coexistence with mutants, and radical terrorist groups of mutants, such as the Exhumes, made war on "normal" humans.
One of the veterans of the Summers Rebellion, a mutant named Hecat'e, stated that it was unacceptable for humans to hunt down criminal mutants. Therefore, she said mutants should police themselves. Hence, Hecat'e and other mutant veterans of the Summers Rebellion formed the Xavier Security Enforcers. The X.S.E was named after Charles Xavier in honor of his dream of peaceful coexistence between mutants and "normal" humans. Hecat'e became the X.S.E's commanding officer.
Since their parents had apparently died, Bishop and Shard lived with their grandmother, who was herself a mutant, until she died. Their grandmother told them stories about the heroism of the X-Men and instructed them to follow Xavier's dream of peace between mutants and the rest of humanity.
One day, when Bishop and Shard were both still children, two X.S.E members were pursuing Virago, a member of the Exhumes, a radical group of mutants who hated "normal" humans. When Virago took Shard as a hostage, Bishop leapt onto Virago's back, making her release his sister. Infuriated, Virago was about to murder Bishop when Sureshot shot her dead. Until then, Bishop had regarded the X.S.E as his enemies and the Exhumes as heroes, but from then onward he wanted to join the X.S.E.
Bishop, Shard, and their grandmother's friend Hancock were attacked by criminal mutants called Billboy and Halftrack. The two criminals killed Hancock and were about to murder Shard. Bishop tried to save Shard, but it was two members of the X.S.E, Amazon and Recoil, who stopped Billboy and Halftrack.
Impressed by Bishop, Amazon and Recoil offered Bishop a position in the X.S.E. Bishop accepted on the condition that Shard be accepted in the X.S.E as well. By now Bishop's own superhuman power had manifested itself. Thus Bishop and Shard became cadets at the X.S.E Academy under Hecat'e's supervision. Among the other members of their class was Bishop's future enemy, Trevor Fitzroy.
Eventually, Bishop and Shard became officers of the X.S.E. Shard, however, became Bishop's commanding officer. Bishop contented himself with a lower rank so that he could work the streets alongside his friends and fellow X.S.E officers, Malcolm and Randall.
Some time after taking command of her own squad in the X.S.E., Shard fell victim to an ambush - set up by her criminal boyfriend Trevor Fitzroy - by the creatures known as Emplates. Turned into one of them, Shard was forced to kill mutants to sup their energy to survive. In a subsequent encounter with the X.S.E., Bishop was forced to kill his own sister rather than let her live as the monster she had become. Shard's essence was transferred into a holographic matrix projector that Bishop wore on his wrist.
Around this time Bishop discovered remnants of the X-Men: A garbled message from Jean Grey warning about a traitor. Bishop confronted the only known survivor who called himself the Witness. Bishop did not trust him and wondered if he was the traitor.
Fitzroy Makes a Run For It
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.
During the quest to stop Legion from altering history, Bishop acted as a chronal anchor with Psylocke using her psychic knife to link them all. They were unsuccessful, triggering the Age of Apocalypse.
Age of Apocalypse
During the Age of Apocalypse, Bishop aged and saw the world change, retaining memories of the incident and beforehand. These memories of the 'real' timeline compelled Magneto and his X-Men to set things right. Using the M'Kraan Crystal, Destiny and Illyana Rasputin sent the elder Bishop to stop Legion. He briefly confronted his younger self, imploring him to 'remember this day.' The elder Bishop stopped Legion and both appeared to be destroyed by Legion's psionic energy. Bishop retained some of his elder self's memories.
Back in the present
Bishop managed to prevent the X-Men's death by Onslaught, absorbing an incredible amount of psionic energy. In light of Gambit not being the 'traitor', the two made peace and learned to work together if not always agreeing on each other's methods.
While in space, Bishop was separated from the other X-Men and ended up with Deathbird. She apparently was to bring him to Apocalypse as part of the Twelve. However, Bishop has no memories of being part of the Twelve.
He remembered being ripped through time by a version of Fitzroy calling himself the Chronomancer. He also met the Witness again, who explained that he was not a future self of Gambit. Chronomancer also found Shard and reverted her to her normal form. The price of victory was high: Shard sacrificed her life for the ultimate good and Bishop found himself filled with chronal energy and hurled through time.
Spiraling through time, Bishop emerged in the present, deep in space. Bishop crashed into a Shi'ar space station, where Professor Charles Xavier and his "Cadre K" of mutant Skrull students were searching for Deathbird - the Shi'ar criminal who appeared to be Bishop's chronal anchor in the present day. A pan-galactic committee had transformed Earth into a prison planet, and Deathbird held a key to penetrate the panel's maximum-security energy barrier. Bishop almost killed Deathbird before she opened an airlock and was blown into space. He allowed himself to be captured and sent to Earth on a mission, where he reunited with the X-Men.
Bishop joined Storm's X-Men team to search for Destiny's diaries. Along the way he revealed his first name, Lucas. Bishop agreed to stay on with Storm's new X.S.E team, whose goal is similar to those of the X.S.E of Bishop's own future.
Bishop also became a consultant in mutant-related matters in the area known as District X, working with Officer Izzy Ortega.
Bishop was one of the few mutants to retain their powers following M-Day. In light of O*N*E's occupying the mansion, Bishop talked extensively with Val Cooper.
Bishop attempted to kill Cable and the Messiah Baby, but he was unsuccessful, and ended up shooting Xavier in the head instead. Bishop escaped from the X-Men, attacked Forge in his Dallas headquarters, and stole time travel technology in the form of a cybernetic arm.
Chasing the Mutant Messiah
Now using a bionic arm, he eventually tracked Cable and the newborn mutant. Upon finding them, he shot Cable twice before being hindered by a local gang. With Cable severely weakened by severe blood loss, he made a risky attack before the gang could find heavier weapons. He later managed to track down Cable, slaying several mutated beasts in the process, and shot the Mutant Messiah. He also found that in the future generated by his choice, Cable would always be revered as a Messianic figure who tried his best to protect the Child, and saved humanity from the very beasts Bishop unwillingly saved Cable from. In his efforts to kill the child Bishop has laid out several traps for Cable throughout the timestream, killing millions in the process, though he doesn't see them as people who actually exist, but as people who wouldn't exist or come back to life if he were to kill Hope.
Messiah War
After multiple failings at killing Hope, Bishop located and enlisted the aid of Stryfe, promising him that he would aid him in killing Apocalypse and Cable. Stryfe and Bishop traveled to a point in the future where Apocalypse was at his weakest and managed to defeat him. Stryfe built an empire using Celestial technology and Bishop became his right hand man, waiting for Cable and Hope to re-emerge. When they did appear along with X-Force, Hope was kidnapped. Bishop betrayed Stryfe and his plot to kill Hope was foiled by Stryfe, who wanted to make her his heir. Both attempts were foiled by Apocalypse, X-Force, and Cable. Cable managed to rescue Hope and escaped yet again. Bishop escaped into the "near future" of the 21st century, with one eye less, reconstructing his arm, vowing to find Hope once again.
