The Galarian Weezing is entirely brownish‑tan in color, with notably large incisors. Its body is covered in numerous curved hairs, primarily concentrated on its chin and tail. It moves by standing upright on all fours, with four seemingly tiny feet. Male Galarian Weezings tend to curl their tails more prominently.

Galarian Weezings have a rather expressionless demeanor, remaining calm and composed no matter what they encounter. They never panic or become flustered; they’re remarkably laid‑back creatures—yet they can execute surprisingly agile movements that belie their appearance. They live in groups, building nests near water sources. Once they find a suitable waterside location, they construct dams to hold back the water and create their nests. Although this temporarily disrupts the flow of water, it actually benefits the local ecosystem. To keep their strong incisors sharp, they constantly gnaw on trees and rocks, gradually wearing away layers of stone and bark around their nests. Comparisons have shown that the growth rate of Galarian Weezing’s incisors is comparable to that of Larvitar. In the past, there have even been bizarre incidents in the Hisui region where Galarian Weezings brazenly wandered into villages and openly chewed through houses.
