The Mutoids

A ship crash-lands on Amzot with a sole occupant on board. Zandor offers assistance and the passenger turns out to be a Mutoid, a race who can change their appearance to anything. The Mutoids plan to use Amzot as a launching site for their missiles to fool their enemies. Can Zandor and the Herculoids stop them in time?

The Crystalites

A meteor crash lands on Quasar and transforms into a giant crystaline object. Zandor investigates and is attacked by the Crystalites while Tara and Dorno are captured in crystal cells. Zandor, Gloop, and Gleep steal uniforms and sneak into the fortress and free Dorno and Tara. Gloop and Zok destroy Kryton's ship and he is defeated.
