This article is about the adrenaline parasites. For the season 8 character, see Rudy Jones.

The Kawatche Caves contained alien parasites. Analysis at Cadmus Labs showed that their physiology is completely unique and their DNA is not from Earth; along with the history of the Kawatche Caves, this suggests that the parasites may be Kryptonian in origin.

Powers and Abilities

The parasites secrete a substance that enlarges the adrenal glands of its host, inducing excessive adrenaline production that makes the host behaving more and more impulsively the longer the parasite is in them, and act on any latent desires or aspirations. In all but two cases, the final result was death by suicide due to utterly irresponsible behavior (and even in those cases, it was only due to pure luck). [1]

Vulnerabilities

The parasites are seemingly susceptible to normal harm. Dr. Frederick Walden and his staff were able to destroy an entire nest using liquid nitrogen.[1]

Appearances

Exposure to the parasites made Pete Ross and Chloe Sullivan do outrageous things. [1]

Lex Luthor then ordered these remaining specimens to be sent to Cadmus Labs in Metropolis. [1]

Sometime after, Lex's scientist Dr. Brody extracts enzymes from the parasites in hopes of making a profitable discovery with them. Desperate to continue his research, he injects a serum (containing the enzymes) into the lab monkey Lester. [2]

Lester broke free to and is encountered by Chloe (who he injects with the serum). Soon after, she injects the serum into Lana, resulting on them causing trouble throughout town. Eventually the serum wears off, and they are left with no memory of what happened. [2]
