Security Guard

The security guard is an unnamed character who has been seen on a few occasions working as security.

Personality
The security guard has a tendency to pepper spray people and tell them to "move along, sir/ma'am."

He is first seen in "Something You Can Do with Your Finger" teaching the ropes to a rookie at the South Park Mall, despite obliviously letting a terrorist proceed with his plan to unleash anthrax upon all of North America. At the end, he seems to be the only person who enjoys Fingerbang's music.

He is later hired by Cartman in "Cartmanland" to prevent unwanted guests into his theme park, especially Stan and Kyle. He tells Cartman that he needs to let more people into the park in order to cover his salary and hire other employees to keep the theme park running.

Trivia

 * He is referred to as "Old Mall Security" and "Older Mall Cop" in the script for "Something You Can Do with Your Finger", "Security Guy" in the script for "Cartmanland", and "Security Guard" in South Park: The Stick of Truth.

South Park: The Stick of Truth
The security guard is seen working as security for the gated community the Black Residence is in and fought by the New Kid in a mandatory quest. The player must first acquire a gas mask from Jimbo's Guns to become immune to the security guard's pepper spray, thus forcing a battle. After he is defeated, he tells the New Kid that he can't look at him without feelings of deep personal shame and plays no further role in the story.
