The Empire and the Rebublic are working a new type of Storm Sworder, the triple S. Stealth Storm Sworders. Major Ralph (the one from the Isenbec unit, with the Redlers) steals the new models and attacks a military base with them. Van manages to take out one of them by launching off a launch ramp, but the other one knocks out everyone in a zoid but Moonbay. Just before Moonbay's Pteras is destroyed, Rosso and Viola show up. Viola is defeated by the triple S, but Rosso destroys it with his older model Storm Sworder.
