Body: Sigma 6 Tunnel Rat
Hands and weapons: Sigma 6 Sky Bat

During a simple sabotage mission Tunnel Rat came to an unfortunate end. While placing the charges he was cornered by Cobra's new weapon, The Rat Catcher Automiton. During the ensuign battle he was unable to escape and was caught in his own blast. The RCA carried his corpse back to Mindbender's lab, who decided that an example needed to be set. The Joe's could not attack Cobra without impunity. No longer with a mind or heartbeat of his own Tunnelrat is no more, there is only the Tunnel Viper.
