Usurper and aerial combatant; his beast form is a red pteranodon. As well as his aerial prowess, Terrorsaur's offensive weaponry included laser cannons in his optics, similar to that of Dinobot, but his preferred weapons were his shoulder-mounted cannons, forearm mounted double barreled cannon and hand-held pistol. He often attempted to overthrow Megatron for leadership of the Predacons (reminiscent of his Decepticon Air Commander predecessor: Starscream) but was never successful in the end. Like Scorponok, he also was destroyed by lava during the Quantum Surge. His beast mode was a Pteranodon.
