Forearm was one of the founding members of the terrorist organization known as the Mutant Liberation Front (or MLF). One of their first missions under the leadership of Stryfe was to liberate the incarcerated New Mutants members Rusty and Skids. They broke them out of prison and the pair joined the MLF out of confusion (and, as later evidence showed, neural implants kept them there). Forearm continued to be a mainstay in the team's ventures, including fighting Wolverine, Sunfire, and X-Factor.
