Elvin Cartman is Eric Cartman's cousin as well as Aunt Lisa and Uncle Stinky's son. Throughout his appearances he is referred to as "Cousin Elvin". He has made two appearances, one being in "Merry Christmas Charlie Manson!" and the other in "Cartmanland". In "Le Petit Tourette " Eric inadvertently tells Butters that he and his cousin have already touched wieners, it is not known if he was referring to Elvin or Fred.
Elvin wears red shoes and has curly dark brown hair. He is almost always seen holding or eating a fudgesicle, with chocolate smeared across his face. Like most of the other Cartmans, he is completely fat. When he got smacked by Cartman, one of his eyes went white and started twitching.
Elvin uses catch phrases similar to Eric Cartman, such as "Sweet!" and "Kickass!", but in different context and usually blurted out.
In the episode, "Merry Christmas Charlie Manson!", when he finally finished his fudgesicle, he began to throw a fit, suggesting he wants another, annoying Cartman; Cartman hits him in the back of the head, causing him to go into a sort of vegetative state and his right eye to dilate. However by the end of the episode he is back to normal.
