As a member of the Mutant Liberation Front, Forearm has always been a mainstay on the terrorist group's roster, even staying through leader changes and incarceration.

One of their first missions under the leadership of Stryfe was to liberate the incarcerated New Mutants members Rusty Collins and Skids.

[volume & issue needed] Later, Garrison Kane encountered Forearm, Wildside, and Sumo in the Canadian mountains and, after a brief scuffle, follows them through their teleportation portal, where he is tortured.

[volume & issue needed] After a series of supposedly unconnected art thefts (all of which are related to Apocalypse), Forearm is one of the few members of the MLF to approach Mister Sinister and propose a trade.

In exchange for a genetic matrix (none other than the Legacy Virus which Stryfe owned), Sinister would hand over the captive Cyclops and Jean Grey.

He breaks Forearm, Reaper, Wildside, and Tempo out of prison,[volume & issue needed] and gives them their first mission: capture Henry Peter Gyrich.

During this time Forearm and Moonstar begin to form a close friendship, as she sees something in him that is different from the other members of the terrorist outfit.

[volume & issue needed] Next the MLF travel to Muir Island where they mean to steal the Legacy Virus data from Moira MacTaggert.

[volume & issue needed] In their last appearance, the MLF once again is trying to steal data on the Legacy Virus, this time from a government institution who is trying to manufacture their own strain of the disease.

Again, through the sabotaging efforts of Moonstar, members of X-Force manage to enter the building in an attempt to stop them.
