Here is Braggadoom, a one-issue villain that appeared in The Thing Two in One, in the team-up with Power Man. He is a monster created in laboratory that gets loose (when you're experimenting with genetics, when you create a monster is inevitable that he gets loose and starts to break havoc) and was finally stopped by the two heroes.

I've made him with a wrestling figure of 12 inches, which I've had to resculpt completely the head, add some epoxi to his hands and reuse some Hulk feet, then painted with different shadows of green.
