History
Quicksilver seemingly had a similar history as his Earth-616 counterpart.
He and the rest of the Avengers Unity Division were investigating a series of superhero murders when it was revealed by M.O.D.O.K. that Deadpool was the killer.
Deadpool then killed the team, believing them to be A.I.M.'s Anti Uncanny Avengers, and believing Quicksilver himself to be Snarky Raptor-Cheetah.[1]
