Spylar resembles a heavily altered theropod dinosaur. He has long, bulky legs which are covered in bulbous scales and bumps, and he also has orange-brown circles on the front of his torso. His head and neck are bright orange, and he has luminescent blue eyes with what appear to be bolts underneath them. His back is covered in tuberous spines, and he has two antenna and a bent spike emerging from his forehead. Spylar has large claws for hands, and two-toed feet.
Spylar transformed from one of the Garogas during Zone Fighter's fight with Wagilar. The two monsters were able to outmatch Zone Fighter until Godzilla arrives to his aid, and the two were able to defeat Wagilar and Spylar.
