Avalugg is a massive Pokémon seemingly formed entirely out of reflective ice. Its top half is flat, with three cracks, one before its stubby tail and two in between its four legs. These legs are cylindrical, and also sport purple cracks at its joints and in between its icy toes. Underneath each toe is a spike, similar to cleats. Large icicles hang from its underside, which nearly touch the ground. Avalugg's head is similar to its body, a cracked wedge of ice with a flattened upper surface. Its mouth has a large underbite, which opens up to reveal four small teeth and purple gums. The head has two white diamond-shaped "ears," and from its chin hangs three bulging spikes, resembling a beard.
Bergmite are known to huddle on top of Avalugg's back, causing it to resemble an aircraft carrier made out of ice. Its cumbersome frame is as hard as steel, able to crush anything that stands in its way.
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.
Wulfric uses an Avalugg in the X & Y arc, it was used to help the Gym Leaders and Y's group get to Geosenge Town to and helped in the attempt to stop the Ultimate weapon from activating.
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. Avalugg's Ice typing 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. Its body also somewhat resembles a tortoise, or perhaps a rhinoceros, ceratopsian, or ankylosaur.
