Wild Wyatt is a Caucasian male with brown hair wearing a brown cowboy suit, blue jeans, and a cowboy hat. In Serious Sam HD and Serious Sam 3: BFE, his outfit is a bit more colorful, as it has some yellow in it.
Wild Wyatt was born into a wealthy family. He graduated from a nice college and got a job as a Wall Street broker. However, he grew tired of this life, so he sold his stocks and moved to a ranch to be a cowboy. Things didn't end for him there, as he met the wife of a famous movie producer, who offered him a starring role in the “Ways of our Wives” soap opera to play as a sheriff. He accepted and played the role for several years, but eventually grew tired of that as well. Eventually, he left the TV industry and joined Serious Sam in his fight against Mental.
