|Season:||Bakuryuu Sentai Abaranger|
Burstosaur Tyrannosaurus (爆竜ティラノサウルス Bakuryū Tiranosaurusu?): Nicknamed "Tyranno" (ティラノ Tirano?), the strongest of the three Burstosaurs. His jaws, strength and sharp claws make him a tough opponent, but his tail is his greatest weapon, able to drill through anything. Although wise, he has a short fuse when it comes to Ryouga. He shows sympathy towards Mai since he understands the feelings of a father because he lost his wife and only child on Dino Earth to the Evolien, so he constantly pushes Ryouga up to be a good father figure for Mai. In fact, in the finale, Tyranno jokingly said to Ryouga that if he and Mai are not happy, he'd come back and get him. Forms the majority of AbarenOh: the head, legs, body, and left arm, and the blade of the Double-Tail Sword. Detaches and donates his tail to another robo combination to add "Drill" suffix to the name, or with the Carnoryūtus's tail, the "Twin Drill" suffix. He ends his sentences with the word "Tera".
