Trevor "Doom" Buck Huntley (Trevor or Doom for short) is a fictional, anthropomorphic black and brown dog, and the little brother of Rex. He was made to be the most annoying character ever in the actual canon.
However Trevor has appeared in a joke RP, called "Sweet and Spicy Love", based on a fictional television series. The show revolves around Trevor and his partner Upsilon cooking "romantic" recipes for an audience. In the roleplay, Trevor does not appear to be as obnoxious; he mainly just acts weird like all the other characters.
