Menace Of The Ancient Vials! While chasing the criminal known as Karnak, the Challengers and their prey end up flying into a strong lightning storm, forcing both parties to land.

Karnak and his companion steal the vials and use them to battle the Challengers.
The Challengers are able to fight off all the effects of the differn vials, from fighting Karnak as a giant, a giant fire creature, a giant octopus, and an army of Karnak duplicates.
