The Scarlet Juggernaut is the leader of the Jamboree of Invincible Super Mutant Girls, better known by their initials as: the J.I.S.M. Girls. Through the use of a high tech ring, her arch nemesis Dr. Steele turns her against the other members of the group. Her first victim is her faithful sidekick, the Rump Ranger.

J-girl Arachnia has the powers of a spider. So Dr. Steele sends over the X-terminator, who quickly subdues her with an industrial strength bug spray. It puts her under his power, and she becomes his moll, fulfilling his every command, starting with a crime spree and ending with hot sex back at the lair.
