Hotshot, AKA, Lou Stewart, is a Marvel Comics villain and an enemy of the Hulk.
Lou Stewart was once a resident of Middletown, which was an isolated town in the middle of a desert. It was the kind of town that no one would miss, which is probably why the the Leader decided to expose it to gamma radiation. He hoped some of it’s inhabitants would survive and join him in his new kingdom of Freehold. Lou was one of only five people to survive a gamma explosion and develop superhuman powers. When Lou acquired his new powers, he went under the alias of Hotshot. He, along with the five survivors also became part of Leader's team known as The Riot Squad.
