Twayne Boneraper is a major character in the TV Series Ugly Americans, and is often portrayed as one of the shows main villains.
He is a muscular, powerful, sadistic, cruel, douchey and stubborn tool of a demon. He is quite hot-tempered, freaking out and inflicting severe violence if someone doesn't laugh about his terrible jokes or even if someone doesn't share his opinions on something as trivial as mustard.
Twayne always relies for things to work out in the end because the times when things start getting bad, Callie, his right hand, or sometimes Mark Lilly come in and help him out of the mess by doing his job.
- He was voiced by Michael-Leon Wooley.
