Head: Mercer v2
Torso: Grunt v2
Arms: Grunt v2
Waist & Legs: Sgt. Slaughter

Ok, this really isn't one of my favorite customs but this LBC was made because: (1) I had several extra unused parts lying around; (2) I just wanted someone to use the extra Barricade accessories that I had, and also probably be Barricade's buddy; and (3) I wanted to use the name Bulldozer on a character (though I first intended it as a Dreadnok).

Anyway, since he's not really that good a custom for me, I decided he'll just be there until I'd need its parts, but time has passed, and I never did break him apart, so I guess I decided to just leave him as is.
