>Sneasler's evolution was the result of Hisuian Sneasel adapting to live on cliffsides in the frozen highlands of Hisui. Due to its severe poison and deadly physical power, no other Pokémon species could defeat Sneasler in its habitat. Using its claws, Sneasler is capable of climbing up walls and cliffs with ease. Unlike its counterpart, Weavile, it prefers to be alone and not live in packs. Sneasler is worshiped in Hisui due to it being one of the 10 ancient Pokémon who received a blessing from Arceus. In particular, it is one of the Ride Pokémon who resides in Coronet Highlands and assist humans.
>Like its pre-evolution, Sneasler may be based on weasels and the kamaitachi, weasel yōkai with sickles on their front legs. However, its humanoid appearance and Poison-type may be based on another yōkai, the ōnyūdō (lit. "big monk"), who take on the appearance of monks and who are said to afflict illness to anyone who sees it. There are stories of animals that can shapeshift into ōnyūdō, one of which being the weasel.
Also should point out it evolves by Razor Claw but in the day, so maybe it evolve in an environment that made it opposite in nature to it's Johtonian counterpart?
