Dr. Alphonse Mephesto is an eccentric geneticist and stereotypical mad scientist, as he lives and works at South Park Genetic Engineering Ranch. Whenever the people of South Park need something beyond the natural, they turn to him. He is the leader of the North American Marlon Brando Look-Alikes (the "other" NAMBLA). He tends to put more than one ass on different animals.
Genetic ExperimentsDr. Mephesto made many genetic animals such like, the four (later five) -assed monkey, a four-assed ostrich, a four-assed mongoose, a mouse/duck, a gorilla/mosquito, a rabbit/fish (this is fake because Cartman said the ears are tied on them), a four-assed frog, a seven-assed Galapagos Turtle, loads of pissed off turkeys and a mutant clone of Stan.
The character is an extended reference to Marlon Brando's portrayal of Dr. Moreau in the 1996 film version of The Island of Dr. Moreau. Like Dr. Moreau, Dr. Mephesto creates strange creatures with his talents- however his creations are things like animals with multiple sets of buttocks. Mephesto believes it is for the good of the Earth, and that one-assed animals are useless and must be destroyed. He even goes as far as presenting a "seven-assed Galapagos Turtle" in an attempt to win a Nobel Prize, but loses to Randy Marsh's "Unified Theory of Fart Thing." He also performs experiments ranging from simple DNA tests to creating a genetic clone of Stan Marsh for his son's project and later a clone of the Muslim prophet Muhammad.
In addition to Brando as Moreau, Mephesto is based at least partially on former UCLA molecular biology professor, Roger Bohman. Both Trey Parker and Matt Stone visited his class based on a recommendation of a friend, and they have admitted to Roger Bohman's more than passing resemblance to Mephesto.
AppearanceHe wears brown trousers and a yellow flowered Hawaiian shirt with an open collar, revealing chest hair. His face is winkled and he wears a brown hat over a bandana that covers his hair. He is usually seen walking with a cane, whose handle is shaped like a pair of buttocks. Mephesto's appearance was tweaked and cleaned up slightly in his most recent appearance in "201", including an updated collar, hat, and gray hair.
Dr. Mephesto has two children, Terrance, who is in the third grade class with the main characters, and Kevin. Although Mephesto is shown to be Terrance's father, they are never seen together save for one episode and he is never shown with the other parents.
- For other uses, see Kevin (disambiguation).
Kevin is Dr. Mephesto's assistant and adoptive "son". He wears similar clothing to Mephesto. He is usually described by others as "That little monkey guy". He seems on first glance to be mute, but he is rumored to have a very sweet, golden voice. He mostly follows Mephesto around. His name is revealed in "Starvin' Marvin" when Chef asks Mephesto "What the hell is that thing supposed to be?"
Kevin's story is told in the song "Mephisto and Kevin" by Primus from Chef Aid: The South Park Album; he was apparently a failed attempt to create a perfect pop singer, a test tube baby created from Michael Jackson's sperm and the egg of an unspecified, musically talented female donor, brought to term inside the womb of a llama. It is also revealed Kevin is legally Dr. Mephesto's son.
He is seen in a crowd in "Freak Strike". Kevin is never heard speaking until the episode "201", in which he yelps in surprise when Cartman/Mitch Conner trick their way into Mephesto's lab. He can also be heard singing at the end of "Mephisto and Kevin".
His brother has never been seen, but it was first said in the episode "Cartman's Mom is Still a Dirty Slut" that he attempts to shoot Mephesto every month on routine. Later in "201" it is revealed the real reason that he shot Mephesto is that he was a Broncos fan, and revealing that Cartman's biological father played for the Broncos may distract the team, which was having a good year.
- Dr. Mephesto is likely a Buddhist as in "An Elephant Makes Love to a Pig" he says "Oh, thank Buddha I found you boys!"
- "Cartman Joins NAMBLA" (Season 4) was Dr. Mephesto's last speaking role until Season 14, in the episode "201". He was downgraded to an occasional background character until "201". Trey Parker later commented that by this point he and Matt Stone simply didn't find the character funny any more, and that they should have made him a member of the real NAMBLA to write him out permanently.
- Dr. Mephesto likely has an ass fetish, due to his experiments constantly having at least four asses.
- In 201 it is revealed that Dr. Mephesto surgically alters his test subjects rather than genetically.
- Dr. Mephesto walks with a cane, indicating he has some sort of limp. He may just carry it however as a fashion. The handle of the cane also seems to be shaped like a hairy ass, which is synonymous with his apparent fetish for asses.
- Dr. Mephesto ways of surgery transformation on animals is the same as Dr Monroe from the book of his island
- Dr. Mephesto is possibly not a fan of The Broncos as he was going to tell Cartman the truth about his father, which would have distracted the team.
- Comedy Central has consistently spelled his name as 'Mephisto' in press materials, however Trey Parker's scripts including those for "An Elephant Makes Love to a Pig", "Cartman Joins NAMBLA" and "201" all spell the name as Mephesto, and the name is pronounced as such.
