Freddy Krueger is the serial killer and antagonist of the A Nightmare on Elm Street franchise, making three appearances in South Park. He first appears in Imaginationland Episodes II and III within the imagination realm, and again in Insheeption as a real character with a different design, refusing to help the government again, not like "that time [he] killed those High School kids to stop the Russians!" (referring to the many High Schoolers he killed in the films) but after they explain innocent lives are at stake he agrees to help, killing Woodsy the Owl to rescue Stan Marsh and Mr. Mackey.
- He Killed Morpheus in Imaginationland.
- since he apears in imaginationland it was assumed he was a fictional character in the south park universe , but the episode insheeption he is depicted as a real person . a likely theroy is that since freddy lives in the dream world and dreams revolve around imagination its likely thats how he apeared in the episode
