Overkill is a Crossbones with the head and armor of one of the deluxe Captain Americas. I put a Trek knee in for the neck joint, and filled in the seam of the Cap mask a bit with FixIt. The triple-gatling is from the Motion Revive KosMos while the single one is from the mini Revoltech Evangelion set.

Overkill became the poster boy for SAW-Viper recruitment after surviving COBRA's attempt at recreating the Super-Soldier Serum. Once upgraded, his combat performance became legendary in the COBRA mess halls, and he's rumored to have killed at least 50 Joes in one firefight, although the true number is much lower.

As a member of the Plague Squad, Guillotine counts him as a valued tool and uses him in nearly every mission.
