Stalker recruited Gladiator from the 75th Ranger Regiment, the same unit he and Barnes came through. Gladiator is a hulking brute of a man. He is the only member of the Joe Team able to state that he bested an Iron Grenadier Heavy in one-on-one combat. He wears the armor of his fallen foe as a tribute to the man under the mask.
His specialty is heavy weapons, including his custom mace, which he uses to bash the skulls of the undead.
