Prehistoric flying reptiles which were summoned by the Pastmaster through a time vortex to serve as his enforcers and bodyguards after his Megasaurus Rex got stuck in the tar pits. They proved effective against the Enforcers, but were defeated by the SWAT Kats. One was fried by the Turbokat’s backwash. Two others flew out of control attempting to follow the jet into a dive and crashed into one another, falling out of the sky. A fourth was knocked through the open time portal along with the Pastmaster after he was defeated.
