An old angry man who claims to have had a disease that started when he was a baby turning his skin color from white to black, he disassociates himself from other African Americans as much as possible as a result of this excuse, and is outspoken in his support of what Huey calls the "white supremacist power structure." He is voiced by Gary Anthony Williams.
