The program was designed to create super-soldiers that the military could use. The name began as Weapon I, then II, and so on. After many attempts and multiple incarnations, Weapon Plus was up to Weapon X. The professor decided to use a team, named Team X, to begin the program. The team included Wolverine, Sabretooth, Mastodon, Maverick, Silver Fox and Wraith. They had false memories implanted in their minds to create the members as "sleepers", able to get behind enemy lines and then be "activated" when needed.
