Jayna was a member of the Super Enemies, which were counterparts of the Super Friends from a parallel universe. When this earth's Superman came to the Universe of Good, and saw the Wonder Twins, he mistook Jayna for his version of Jayna.
The evil Zan and Jayna don't have any dialogue in this episode; they only appear in shadow, in the darkened Hall of Evil.
