The Myzarian Cyborg is a gigantic creature part alien part machine from the planet Myzar 3. He becomes trapped in the Land of the Lost after colliding with Simon Cardenas, another time traveler, while traveling through the time/space corridor, damaging his time device. Shortly after his arrival, he confronts Scarface and manages to beat him. Later, he attacks Simon, Annie Porter and Tasha, but Annie blinds him with camera flashes and he falls off a cliff.
However, the Cyborg survives the fall. He currently lives in a cave in the mountains that he has made into a base of operations and attacks anyone who comes near.
- He looks very similar to the Rancor.
