David is a stick figure that is poorly drawn. His outline and facial details are gray, and his face is white. He turns red and has yellow zig-zagged lines that resemble lightning bolts surrounding him when he gets angry. He appears to have a blank stare most of the time.

In "Four Goes Too Far", although we do not see it actually happening, he became orange, due to him being safe from elimination and he kept this color since. He retains this character change in TPOT as well.
