Jiel is a young woman whose tribe of villagers were enslaved by the wizard, Skullus during Wizard Wars. Skullus used them as foot soldiers in his continuing war against his arch-enemy, the cyborg wizard, Octagon. Thundarr, Ariel and Ookla rescued Jiel when they arrived on the scene to battle Skullus, who retreated and destroyed her village in the process. In return, she aided them bringing about the defeat of both wizards. Afterwards, Jiel's people were freed from Skullus' control.
