Hisuian Avalugg

Avalugg is the Ice-type Iceberg Pokémon introduced in Generation VI, evolving from Bergmite. Its body resembles a glacial slab, and it is often depicted with smaller Bergmite riding atop its broad, flat back as it slowly traverses snowy mountains. The ice armor covering its lower jaw is said to be harder than steel, capable of shattering rock as it barrels through deep snow. A regional Hisuian form, Ice/Rock-type, was later introduced with a more rugged, mountainous appearance.

The Japanese name クレベース (Kurebēsu) likely combines 'crevasse' (a deep crack in glacial ice) with 'base,' evoking a massive, immovable foundation of ice. The English name 'Avalugg' fuses 'avalanche' with 'lug' (or 'glug'/'iceberg'), suggesting a heavy, hulking mass of moving ice. Both names emphasize its identity as a slow but unstoppable iceberg-like creature.
