Trevor's background is uncertain and often suspect, given that all players ever hear of it is from Trevor himself - hardly a reliable source. He was voiced by Steven Ogg, who also played Professor Venomous and Shadowy Figure in OK K.O.! Let's be Heroes, and Simon in The Walking Dead.
He is also the archenemy of Steve Haines and Wei Cheng. Additionally, he is Michael De Santa's best friend as well as Franklin Clinton. He is a criminally insane and psychotic crime lord and the titular founder of his weapons company "Trevor Philips Enterprises". Trevor Philips (born 1965) is one of the three main protagonists of Grand Theft Auto V, as well as a main character in Grand Theft Auto Online. I feel like taking you out, Devo, so that's what I'm doing. There are people who are useful to you, and people who ain't, and the people who ain't got to go. ~ Trevor explaining his life's work to Tao Chang and his translator. Y'know, I've always wanted to be an international drug dealer and.weapons trader. I mean, since I was a little kid I-I dreamt big.
