Here's Scumbug from the vintage Teenage Mutant Ninja Turtles action figure line. I always thought he was neat... although, after spending so much time looking at him for this, he's actually somewhat disturbing.
I think they may all be smiling... at least on the inside. The most disturbing thing about the toy is the way his skin is ripping off and, I didn't draw this, but how roaches are crawling through his skin from inside him.
D: There were a lot of somewhat disturbing things about the old villians, who I love none the less for it. The younger generations these days have it too soft in some ways, and too hardcore in others. No happy balance.

Ten seconds of looking at this, and the disturbance definitely comes across. XD
