Badass Thugs are heavily muscled prisoners in The Secret Armory of General Knoxx armed with shotguns, or on rare occasions rocket launchers. They wear unique face masks and have heavily scarred torsos.
The Badass Thug's fighting style is a ponderous walk, ignoring cover while enduring punishment as they fire or reload. Due to their slow walk, their enlarged heads make good targets for critical hit. Like all prisoners, they are vulnerable to incendiary attacks.
- The naming convention of a Badass Thug deviates considerably from common Borderlands naming conventions, in that rather than being a badass version of a Bandit Thug it is simply a Bruiser with a shotgun.
- The Badass Thug uses the same model as a bruiser but textured with a heavily scratched torso and striped pants.
