Harvey Brown was the president and co-founder of Wall-Mart in "Something Wall-Mart This Way Comes". The Boys found him brooding in a bar near the Wall-Mart headquarters in Bentonville, Arkansas. He told the boys that the only way to kill a Wall-Mart was to destroy its heart (a glass mirror near the television department). His guilt got the best of him, and he then committed suicide, asking the boys to tell the world that he was sorry. Thanks to his help, Randy, Kyle and Stan were able to destroy the Wall-Mart in South Park.
He has graying brown hair, and bags under his eyes, presumably from the guilt of opening Wall-Mart. He wore a white, button-up undershirt, brown coat, a messily put on brown tie, and brown pants.
In "Something Wall-Mart This Way Comes", he was incredibly remorseful and guilty over establishing a one-stop super store like Wall-Mart in 1987, only for it to go out of control and form a mind of its own in four years, becoming extremely depressed and eventually shooting himself.
