Cis is an android created by Rotwang whose system has information on all currently active heroes.

While in transport, the vehicle carrying her was struck by lightning and she escaped. Keith met her in a park and, though she seemed only be able to say a set number of phrases ("I don't know", "Yes", "No" and "I'm sorry"), his conversations with her boosted his confidence after having lost his title as King of Heroes, eventually leading him to fall in love with her.
