Aurorus is a huge dinosaur-like Pokémon bearing resemblance to the Amargosaurus, with light blue colored skin, a teal stomach, and blue eyes.

When it emits a cry, the thin blue-tipped membrane on its head ripples with a light green color, while it attacks, the membrane turns orange. With the icy crystals that line its sides,Aurorus can freeze the surrounding air and trap its foes in ice.
Aurorus is an evolved form of Amaura, by leveling up to 39 or above at night.
