Dinozaurs

Dino Knights

When the Dragozaurs first attack Earth, the planet chooses a select number of prehistoric animals to fight them, converting them into the Dino Knights (ダイノソルジャー, Dinosoldiers). Normally fossilized, a Dino Knight assumes a more metallic form when re-animated. The command to power up the Dino Knights with the Dino Daggers is "Dino Power, Energize!". The Dino Knights' fossil forms reside in the Dinotarium. The Dino Knights are:
