Gladiator-X: Professor Geoffrey de Sade was a world-class historian and taught at some of the finest institutions of higher learning around the world. That was, until Cobra kidnapped a group of geniuses and forced them to do their bidding on yet another failed attempt to defeat the Joe team. Even though all the captives were set free in the end, Geoffrey had somehow already tapped into the brutality of gladiatorial combat. He appropriated various armor and gear to outfit himself for his new life...as a bloodthirsty gladiator! Cobra wants him on their side, and the Joes want to help heal his fractured psyche. Gladiator-X, as he calls himself, just wants to spill more blood. Apparently others have joined his lust for plasma as well.
Gas-X: His body odor is so pungent that he himself has to wear a gas mask...yeah, it's that bad. It is not known how Gladiator-X and the X-Ecutionerz tolerate being around him, but it could have something to do with the ability to clear a crowded bar QUICK.
X-Ecutionerz: The nameless and semi-faceless heavy gunners of the Shadow Squad. Once under the tutelage of Snake Eyes; they traded in their samurai swords for M56 smart-guns, a pair of forearm daggers, and a 9mm.
Their current assignment is to track down Red Cent and turn him into swiss cheese...but he is being protected by the Copper Corps. Difficult, this job is going to be, hmmpphh.
