In Hisui, Avalugg has a dual-type Ice/Rockregional form. It evolves from Bergmite starting at level 37. All Bergmite in Hisui will evolve into this form regardless of their origin.
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.
Hisuian Avalugg is noticeably smaller than its Kalosian counterpart, weighing only half as much. Its entire body is made of stone, whilst its top, along with its head, are covered in a layer of solid ice. The head of Hisuian Avalugg is larger compared to Kalosian Avalugg, and has two large tusk-like plates on its lower jaw. These armored plates are stronger than steel, and allow Hisuian Avalugg to break through boulders easily and shovel through deep snow. Hisuian Avalugg are known to be rather docile.
A special Hisuian Avalugg is worshiped by the Hisui people due to it being one of the 10 ancient Pokémon who received a blessing from Arceus. It is one of the Noble Pokémon who resides in Alabaster Icelands watched by a Warden. This Hisuian Avalugg is much larger than others of its species, being similar to Dynamaxed Pokémon in size.
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.
The armor of ice covering its lower jaw puts steel to shame and can shatter rocks with ease. This Pokémon barrels along steep mountain paths, cleaving through the deep snow.
Game locations
This Pokémon was unavailable prior to Generation VI.
By floating on top of the lake, Avalugg can pass itself off as an ice floe. It doesn’t seem to mind if other Pokémon hitch a ride on top of it to cross the water.
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.
Hisuian Avalugg may be based on a mountain covered with glacier, or the glacier itself. The ice plates covering its jaws have the same appearance and function as the blades of a snowplow, which are used to clear snow from a path. Its ability to break through rocks easily may be inspired by the process of plucking, which is how glaciers erode bedrock as they move.
Name origin
Avalugg may be a combination of avalanche and lug (to carry or drag heavy objects, or a big/clumsy person).
