A new batch of aliens led by Konar use an atmosphere asborber on Quasar while the Herculoids look on. When Zandar and the rest go to investigate the aliens open fire. The Herculoids drive them back but the aliens respond with a gun capable of turning rock to magma. Zandor ""surrenders"" and then they sneak out and shut down the absorber, then fight and defeat the alien zorbots - Konar runs like a bunny.
