In a collaboration between the CIA and CSIS, Team X was a black ops unit of highly trained operatives acting on behalf of America and Canada. They also became test subjects for the Weapon X Program, and those without a natural healing factor were given an age-suppression factor derived from the abilities of agents Logan and Creed.
Although active for some significant length of time, the exact details of Team X's formation and disbanding remain unclear, particularly because this period in their lives was heavily twisted by Weapon X's memory implant program.
