Adrena Lynn was a TV teen action star who specialized in "extreme" death-defying stunts. She also seems to like using the word "freaky" in sentences (she puts emphasis on the eaky, but not the fr). However, it is possible that the experience was a key element in Dr. Possible being distrustful of "show folk" and celebrities, particularly after Kim's brothers, Jim and Tim, were both injured in an hamfisted attempt to replicate one of her 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. It was really Ron, who exposed her to the press as being a "FAKE", resulting in her show being cancelled. Adrena Lynn attempted to get revenge on Kim. Lynn learns about Kim dating a football player named Brick Flagg (actually, a fake story Ron made up to get himself on the papers for Middleton High) and kidnaps him, taking him to the abandoned Middleton Fairgrounds and tying him on a coaster. Even after Ron confessed that he was the one responsible for exposing her as fake and her show getting cancelled, and he made the whole Brick thing up, Lynn just shrugs it off.
Lynn was eventually was defeated and sent off to jail after a death-defying battle at an abandoned circus that ended with Adrena Lynn being exposed once again as a coward.
Adrena Lynn has a hard character, an extreme form of a bad and powerful girl. She adores the danger and tries to take it to extremes. In reality, she's a very cowardly person, having faked every extreme stunt in her career.
