Mr Sinister had a bunch of teams. Nasty Boys were, I'm pretty sure, the most short lived of them. After their initial two part appearance, they've only shown up a few times here and there. Usually one offs. Much better remembered for showing up in the X-Men cartoon. Also, this guy was annoying to make. Too much hair.

Feet were from a Thor movie Frost Giant. Head was from a BossFight male blank. Ponytail was from Loki. Sculpted on the gloves, arm bands, leg bands, belt, collar, and all the fur. Full repaint, and all done!
