Return of Sta-Lak

Sta-Lak returns to Quasar seeking vengeance and equipped with robot duplicates of Igoo, Zok, and Tundro. He captures Dorno and Tara and Zandor and the others are forced to go into his volcano lair. The robot duplicates prove no match to the originals even though the robot Igoo can spin at high speeds and has multiple arms, and the mecho-Tundro can fly. Sta-Lak enters a bubble and flees into a volcanic lavahole.
