The Lord of Darkness
The shop manager for the Kingdom of Kupa Keep, the Lord of Darkness was once a simple shopkeep for the Grand Wizard King named Clyde, and was often abused by his king, but he remained loyal until the arrival of the New Kid. After being beaten up by both the newcomer and invading elves who subsequently took the Stick of Truth, the Kingdom's most-prized artifact, Clyde was banished from space and time by the Wizard King. Within hours, he was plotting his comeback - and his revenge. Using the combined forces of his dad, er, slave, the Vampire Kids, the Girl Bullies, Sixth Graders and his ability to create Nazi Zombies with Taco Bell Green Sauce, the Lord of Darkness and Feldspar the Thief sought to rule the world.
He was later banished from space and time again and went back to normal as Clyde Donovan.
The player (Douchebag) first speaks with Clyde to purchase their weapon and get his friend request before beating him up in the tutorial level. Clyde blames his abuse on the new kid and disappears when banished from space and time, withdrawing his friend request. At the end of the second day in gameplay, a video of him as the Lord of Darkness is played at the school, forcing the Humans and Elves to team up in hopes of defeating him, and the game's final levels take place in his huge evil tower, built by his dad. The player faces all of his minions until Clyde who uses Nazi Zombie Chef as a last resort. Throughout the battle, he insists Chef obey, even when he may break his trance, and finally lights him on fire when he snaps out of it for good, leading to Douchebag farting on him and killing Chef once and for all.
A deleted sequence in one of the game's original trailers showed a massive Clyde destroying City Hall as the main boys run from him. The final game contains no 'final showdown' with Clyde, who is defeated in a cutscene by the Wizard King.
- His character arc in the Black Friday trilogy as Clyde and in the game somewhat mirror Butters' character arc in the first few seasons after his debut: being forced to do small, menial tasks and getting beat up before eventually rebelling with an new "evil" identity.
- After the release of "South Park: The Stick of Truth" in March 2014, many fans worried Clyde had died falling from the tower as the Lord of Darkness, but he reappeared without incident in "Gluten Free Ebola" with no reference to the game's events.
