Debut Episode/Fic "An Elephant Makes Love to a Pig"

Terrance Mephesto is a member of the fourth grade class of South Park Elementary in South Park. He is Bill Allen and Fosse McDonald's closest friend, and was the son of Dr. Alphonse Mephesto. He appeared most prominently in "An Elephant Makes Love to a Pig".

Please visit his article on the South Park Archives for more information.


Terrance wears a purple jacket, with a black neck tie, and yellow suspenders going down to orange pants. His hair and eyebrows are dark brown and he has prominent chin.


Terrance was the top student in the class, rivaled only by Kyle Broflovski, and known for his strong interest in science and genetics. He usually hung around with Bill Allen and Fosse McDonald, despite the obvious intelligence difference.


Although he has not had a second speaking appearance in the series, Terrance remained an active background character for over twenty years after his debut episode, occasionally being involved with foreground action, such as in the film and in "Raisins", much like his friends Bill and Fosse, and did not appear to be discarded entirely from the show.

Contradicting this, however, the game South Park: The Fractured But Whole features the first dialogue reference to Terrance since his debut episode, where Dr. Mephesto refers to him as my "dead son" and displays mutant genetic clones of Terrance to the main boys, explaining that Terrance died shortly after the episode's events during the Season 1 episode "Mecha-Streisand".

Despite this, he continued to appear in the background of episodes produced after the game's release including "SUPER HARD PCness" in Season 21, and was included as a playable character in South Park: Phone Destroyer, a mobile game also published by Ubisoft.

His exact fate is therefore a point of controversy among fans, though the fan-run South Park Archives considers him deceased.
