Editing Terrance Mephesto (section)

==Video Games==
===[[South Park: The Stick of Truth]]===
An icon for him (labeled '''Terrence''') is included in the game's files, but he was cut from the final game. His possible role is unknown.

===[[South Park: The Fractured But Whole]]===
During a tour of the main characters through the heavily revised [[South Park Genetic Engineering Ranch]], the elder Dr. Mephesto displays on the third floor of his residence a variety of horrifying mutations of his "dead son" on display, using them to illustrate that his technology could someday help human beings as well. He remarks that "most people don't remember that [he] once had a young child named Terrance" and explains that Terrance was killed tragically by [[Mecha-Streisand]] when some children in town were playing with a relic that belonged to [[Barbra Streisand]]. It seems suggested his efforts to refurbish the lab are related to bringing him back, but Mephesto insists that he has no intentions of this, only to give his son additional asses so he could rest in peace.

As Mephesto's ranch looks wildly different from the show, his assistant Kevin is not present, and Terrance has continued to appear in the background of episodes after its release, such as "[[Sons a Witches]]", as well as several episodes after his death is suggested to have taken place, these scenes are presumably non-canon. (see 'Death' below)

===[[South Park: Phone Destroyer]]===
Terrance can be seen in his father's laboratory, as can his brother Kevin, during the Create-a-Kid process at the beginning of the game. He is also a playable character, where he uses a device with spinning blades and large engines to perform as "an aerial bomber who deals heavy damage". His card is 'neutral', not tied to any specific theme, and considered 'rare' though it can still be unlocked from relatively early in the game.
*Matt Stone recorded new dialogue for the character in this game, but his voice is pitched down, sounding similar to [[Bill Allen]].
