Snibunna

Diamond +2: They live in cold regions, forming groups of four or five that hunt prey with impressive coordination.

Pearl: It sends signals to others by carving odd patterns in frost- covered trees and ice.

Platinum +2: Evolution made it even more devious. It communicates by clawing signs in boulders.

HeartGold +3: It lives in snowy regions. It carves patterns in trees with its claws as a signal to others.

Black 2 / White 2: They communicate by clawing signs in boulders and work together to surround enemies.

Sun: They travel in groups of four or five, leaving signs for one another on trees and rocks. They bring down their prey with coordinated attacks.

Moon: They dwell in cold places. This Pokémon’s main food source in Alola is Vulpix and Sandshrew, which they carefully divide among their group.

Ultra Sun: One Weavile will trip a Sandshrew and flip it over, and then another Weavile will deal the finishing blow with its sharp claws.

Ultra Moon: Thanks to its increased intelligence, scrapping over food is a thing of the past. A scratch from its claws will give you a case of frostbite!

Sword: They attack their quarry in packs. Prey as large as Mamoswine easily fall to the teamwork of a group of Weavile.

Shield: With its claws, it leaves behind signs for its friends to find. The number of distinct signs is said to be over 500.

Legends: Arceus: This species corners prey as a pack, under the guidance of a leader. Weavile displays increased cunning, leading me to speculate that its evolution caused further brain development.
