Whiplash's is similar to the stereotypical western outlaw: Poor hygiene, gruff voice, sadistic streak, overall rough, tough and thuggish personality with few redeeming qualities.
After Otis and his friends opened a wild west theme park, Whiplash attempted to rob them. When he was unwittingly beaten by Otis, he swore revenge. He returned at high noon to challenge Otis to a showdown, but just as Otis was about to lose and be shot, Pig arrived on unicorns knocking Whiplash out of the park. It is unknown if Whiplash will ever return.
