- Zok, (voiced by Mike Road), a flying dragon. He emits laser beams from his eyes and tail. His eyes also produced a
"nega-beam" that could neutralize certain energy attacks. Zok could survive in space unaided, was capable of interstellar travel, and could breathe fire.
- Igoo, (voiced by Mike Road), a rock ape. An extremely large and powerful simian, he had extremely
dense skin and was nearly invulnerable to harm. Igoo has a great fondness and devotion for Tarra, and will do anything for
her. He will go to any lengths to defend Tara.
- Tundro, (voiced by Mike Road), a ten-legged rhino-triceratops. He shoots explosive energy rocks from his cannon-horn (Zandor, Tarra, and Dorno also occasionally
shot similar rocks with slingshots). His natural armor-plating was exceptionally strong, similar to Igoo's rock skin. His
legs had the ability to extend to a remarkable length, somewhat like stilts. He could also spin his head at blinding speed, allowing
him to drill through solid rock. He also had the ability to make magnificent leaps.
- Gloop & Gleep, (both voiced by Don Messick), two protoplastic creatures. They could assume any
shape or form that they chose; for instance, if they spot an allied human falling, they can leap towards them to make physical
contact and spread out their mass to become a crude parachute to allow the human to land safely. They could also
subdivide themselves into multiple smaller units (each having eyes), which moved more or less in unison. Gloop was the larger
of the two, while Gleep seemed to be a juvenile and was often paired off with young Dorno. Their unique physical makeup apparently
provided even more protection from physical or energy-based attacks than Igoo's stony hide. They seemed to be able to absorb
energy blasts and laser beams that are directed towards them.
