Dr. Gonzo is Duke's insane attorney, who is a surrogate of Oscar Zeta Acosta, and is the main character in the film, alongside Raoul Duke. He is usually seen behaving on a level slightly above that of a wild animal, constantly on drugs, and looking for trouble.
What is interesting is that he seems to have a lack of ability to care about what's going on around him most of the time and if it does indeed effect him, it is profoundly negative.
Physical appearance[]
Dr. Gonzo is noticably bigger than Raoul, at 6 feet 2 inches. He is also overweight and most likely obese. In the book he is described as a “300 pound Samoan”.
