Craig is stoic, cynical, apathetic, deadpan, and monotone. He is also logical, mature, pragmatic, and sarcastic. He prefers to be left alone, and has a compulsive tendency to flip people off, usually for no discernible reason. He only loves his guinea pig, "Stripe".

Craig goes to South Park High School, he is generally disliked as he is seen as the biggest asshole at school. He's an Astronomy nerd, and openly homosexual, and autistic. He hardly cares what others think of him.
