    Under the Scarlet Jungle of Krypton lies a condemned device, with which scientist Mal-Va planned to send his assistant Zol-Mar into the past and then return him after 10 minutes. However, Zol-Mar had ambitions of his own and sabotaged the machine, intending to stay in the past and be acclaimed for his mastery of the technologically advanced devices he carried with him. But the experiment, and Zol-Mar's plans, went horribly wrong when the time travel machine sent Zol-Mar in the wrong direction.
