What about Pokémon?: Aurorus

Aurorus is a Rock/Ice-type Pokémon introduced in Generation VI. It is also known as the Tundra Pokémon. It is a Fossil Pokémon.

Aurorus' name comes from "aurora" and the suffix "saurus".

Aurorus is a huge dinosaur-like Pokémon with light blue colored skin, a teal stomach, and blue eyes. It has many icy gems on the sides of its body and a long, curled tail. 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.

The diamond-shaped crystals on its body expel air as cold as -240 degrees Fahrenheit, surrounding its enemies and encasing them in ice. Using its diamond-shaped crystals, it can instantly create a wall of ice to block an opponent's attack.

Aurorus evolves from Amaura at level 39 only at night. Both Pokémon have the same types.
