Clyde Donovan is one of the main antagonists in South Park: The Stick of Truth. He is a merchant at Kupa Keep, and sells weapons and armor, until he is banished for not protecting the stick. 
Players lay siege on his fortress to recover the stick. He re-animated Chef using the toxic waste, but fails to win and Cartman banishes him from space and time again, kicking him off of the tower. He's shown to fall onto the ground from his tower afterwords, and is never seen in the game again.
