The Zords of Power Rangers Dino Thunder are fictional dinosaur-like robots known as Biozords that prior to the series were created by Tommy Oliver and Anton Mercer during their collaboration. They are mostly maintained by Tommy's friend Hayley. The first set is composed of the Tyrannozord, Tricerazord, and Pterazord, which when combined become the Thundersaurus Megazord. The Black Ranger has the Brachiozord, which acts as a carrier for the other Biozords, including the additional Cephalozord, Dimetrozord, Parasaurzord, Ankylozord, and Stegazord, each of which can combine with the Thundersaurus Megazord to give it a new weapon. The White Ranger has his own Dragozord as well as control over the Stegazord, which when combined become the Dino Stegazord. The Triassic Ranger also has control over the Mezodon Rover and Triassic Megarover, which when combined become the Mezodon Megazord. The Mezodon Megazord also can combine with the Cephalozord, Dimetrozord, Parasaurzord, and Ankylozord to become the Triceramax Megazord. The Thundersaurus Megazord, Dino Stegazord, and some parts of the Mezodon Megazord, are also used to become the Valkasaurus Megazord. The Blizzard Megazord is also seen, made up of an evil Carnotaurzord and Chasmozord.
