Uncle Hoyt is Brewster's uncle. Hoyt is a very angry man who is unhappy having to take custody of his two nephews after leaving his own wife and children. However, Hoyt knows that Brewster can take his pain and his injuries. This causes Hoyt to hold on tight to Brewster, never allowing him out of the house except for school, so that no one else will ever learn of what he can do and try to take him away. Somehow Hoyt manages to hold on to his anger around Brewster and he often uses it to lash out at Brewster by injuring Cody. In the end, Brewster stops caring for his uncle, leaving his uncle to die of a stroke.
