For other uses, see Kevin (disambiguation).

Kevin Mephesto is Dr. Alphonse Mephesto's adopted son and lab assistant. He first appeared in the Season One episode, "An Elephant Makes Love to a Pig".


Kevin is often seen as Dr. Mephesto's silent, but faithful lab assistant. In "An Elephant Makes Love to a Pig", he helps Mephesto breed a pot-belly pig and an elephant. In "Starvin' Marvin", Chef is inspiring the town to help solve the turkey crisis, when he asks Mephesto what Kevin is, who replies by saying that it wasn't an important matter.

During "Cartman's Mom is a Dirty Slut" and "Cartman's Mom is Still a Dirty Slut", Kevin's name is revealed, and he assists Dr. Mephesto in finding out who Cartman's real father is. In "Cartman's Mom is a Dirty Slut", when announcing the potential candidates for Cartman's father, the cliffhanger narrator refers to him as "that little monkey guy who follows Dr. Mephesto around".

He later reappears in subsequent episodes, usually alongside Dr. Mephesto. Until "201", where he screams in distress, Kevin was entirely silent.

Chef Aid: The South Park Album

Kevin's story is told in the song "Mephesto 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.
