Tempus is an enemy of Space Ghost in Hannah-Barbera's Space Stars. A Time Satellite fires beams on the planet Glax-3 that turns back time on Glax-3.
Space Ghost discovers that Tempus the Time Master is behind this in a plot to harvest Luxor in order to use it to build a Time Shredder. He is about to succeed in dropping Space Ghost and his friends into the Pompeii eruption, but the monkey presses a "recall and dissolve" button which stops it. Space Ghost then defeats Tempus and presumbably imprisons him.
