Avalugg is a massive Pokémon covered almost entirely in semi-transparent ice. Through the ice on its head, diamond-shaped, yellow eyes with purple sclerae are visible. Its head is wedge-shaped with a white diamond-shaped ice chunk on each side in place of ears, a dark chink in the ice over each eye, a crack just before the tip of its snout, and a beard of short icicles. The top of Avalugg's body is flat with three horizontal cracks along the surface and there is a collection of icicles along its belly. Its legs are cylindrical with cracks just before its foot and in-between its toes; underneath each toe is a spiked claw.
Avalugg's massive body is hard as steel. This allows it to crush anything in its way. It has been known to allow Bergmite to huddle on top of its back, which causes it to resemble an aircraft carrier. Avalugg's bulk makes it the heaviestIce-type.
Avalugg, the Iceberg Pokémon and the evolved form of Bergmite. Avalugg's ice covered body is hard as steel. It uses its body to demolish any obstacle that gets in its way.
Avalugg appears to be based on a tabular iceberg or a stalactite. It may be a representation of the submerged part of the iceberg, which is immense in comparison with the tip. Its body also resembles an aetosaur, or possibly a tortoise.
Avalugg's Ice type and being likened to an aircraft carrier may be a reference to Project Habakkuk, a plan conceived by the Allies in World War II to build an aircraft carrier from pykrete, a combination of ice and wood pulp. The cracks in its body deepen in daytime heat and heal throughout the night, which is likely a reference to the polar ice caps shrinking in the summer and expanding in the winter.
