A single-episode villain, Adrena Lynn was a TV teen action star who specialized in "extreme" death-defying stunts. In reality, she faked all of her stunts, and was exposed by Kim and Ron when Kim tried to save Lynn from a failed bungee jump stunt only to discover Lynn didn't do the stunt at all and was using a stuffed stunt-double dummy. She also seems to like using the word "freaky" in sentences (she puts emphasis on the eaky, but not the fr). Her name is a play on the word adrenaline.
Fun Fact: Adrena Lynn is featured in the Nintendo DS videogame: Global Gemini.
