Agent X (2002-04)
Agent X (Nijo Minamiyori, alias Alex Hayden) is a fictional mercenary whose adventures have been published by Marvel Comics. He first appeared in Agent X #1 (Sept 2002), by Gail Simone and UDON.The series, a pseudo-spin-off of Deadpool, continued the cynical, slapstick, and highly polished action which had characterized its parent series. Indeed, a central feature of Agent X was the question of the title character's identity, sometimes implied to be Deadpool himself. Deadpool refers to Agent X as his "Earth-2 Counterpart", a reference to DC Comics' designation of different Earths for different iterations of identical and similar characters.
