Alex Glick is voiced by himself. Alex Glick had won a contest which allowed him to be in South Park for a guest appearance in Season Seven episode, "Red Man's Greed", for being the highest bidder at charity auction to benefit AIDS research.
Alex Glick has only been in one episode, making his first and only appearance in the episode "Red Man's Greed". It is unknown whether his character is modeled after his real appearance.
Alex Glick wears a red hoody with "ALEX" written on it. He has a noticeable chin which makes his head look different from most of the other characters.
Alex Glick rarely ever makes a large contribution to any situation. He usually appears in a conversation with the main characters and makes a motivational statement. He has also made a statement on how South Park is more than just a town at the end, taking the role to tell the 'moral' of the episode.
