Zol-Mar is the young apprentice of Kryptonian scientist Mal-Va. Zol idolizes Dar-Nx, a military leader from Krypton's distant past. Using betrayal and trickery, Zol steals devices from fellow inventors, then sabotages his own master's latest creation, the Tempor device. The invention is used to send men back in time and return them to the present. Due to Zol's sabotage however, he will stay in the past and use the stolen inventions to make himself the ruler of Krypton. During the transport, Mal-Va realizes the machine is malfunctioning and attempts to bring Zol back to the present. However, the sabotaged machine fails. Instead of returning Zol to the present, he is sent fifty years into the future. Unbeknownst to Mal, Zol arrives in the future on the day after the destruction of Krypton. he materializes in dead space and is instantly killed.
