Here's another well-known recipe: take 1st appearance Hulk and turn him into Awesome Android. I carved down the ragged pants and re-sculpted them. It's kind of a cross between his Awesome Andy look from She-Hulk and his original outfit... which was some weird V-shaped brown pair of panties.

The head is made from two art-gum erasers that I cut down and sculpted over. I gave him a bit of a smiley face on one side, and a small indent line on the back to represent his classic look, so the head can be turned around to switch "faces".
