Thundersaurus Megazord
The primary Megazord of Dino Thunder, the Thundersaurus Megazord's main mode is created by combining the Tyranno, Ptera, and Tricerazords. However, several combinations exist that incorporate the Cephalo, Dimetro, Parasaur, Ankylo, and Stegozords. It can also be formed in an "incomplete" form with only the Tyranno and Tricerazords.
The Thundersaurus Megazord had a variety attacks at its disposal. It had a sucker-punch attack that Ethan dubbed the Tricera Fist and another attack where the Megazord uses the Pterazord as a boomerang, which Kira calls the Pterarang. The Megazord could also unleash a fire attack from the Tyrannozord's mouth called the Fire Breath and the Tyrannozord still seems to function by biting (as demonstrated in "Diva in Distress" when it bit Donkeyvac's nose), but the Thundersaurus Megazord's most powerful attack is the Tyranno Drill/Dino Drill where the Tyrannozord's tail (forming the left arm) activates as a giant drill and impales enemies. It is usually used as the finishing blow. The Thundersaurus Megazord also can detach part of the Tyrannozord's tail and the Tricerazord's head to reveal arms and can use the Tricerazord's head as a shield with its left arm and the Tyrannozord and Tricerazord's tails with its right arm as a satellite which is called Satellite Mode. In this mode it could use the Tyranno Tail attack in which it throws the sword like a spear. It was self-destructed to destroy the Zelzord.
