>>54784842>RattataBecame invasive in Alola, predators made it become noctural and thus gain Dark type
>RaichuIn-game explanation is it ate too many sweets. Has always had a connection to surfing anyway. Retains Electric-type so who cares
>SandshrewOld dex entries mention it storing moisture in its shell, which can explain the igloo. Goes from burrowing in sand to burrowing in snow
>VulpixHad to adapt to icy mountains. Ultimately just swapping one element for another
>DiglettBurrowing in volcanic soil gave it ferrous and magnetic "hair"
>MeowthBeing a pampered and specially bred little shit made it into a Dark-type. Being bred by vikings made it into a Steel-type (for some reason?)
>GrowlitheAlternate past breed from Hisui. Still part Fire so who cares
>GeodudeThe rocks in Alola have more magnetic minerals
>PonytaThe mystical energies of the Galarian forests caused it to change types from Fire to Psychic
>SlowpokeIts diet changed its typing and where the Shellder bites down
>Farfetch'dThey use bigger, badder leeks in Galar
>GrimerEats a different kind of trash, giving it Dark type
>VoltorbAn alternate past form that more closely resembles tree seeds, meaning it has Grass type
>ExeggutorBetter sunlight = taller tree. Dragon type is both a pun on its inspiration and also because it unlocked latent powers
>WeezingEats different pollution
>Mr. MimeThis is honestly a weird one and I can't figure it out. It mimics tap dancing so its Ice-type? This one is definitely contrived as fuck, no way around it
>TaurosDifferent breeds for bullfighting
>Galarian BirdsNot actually the Kanto birds at all, just lookalikes
>PLA StartersInfluenced by the climate/spiritual energy/battling techniques of Hisui
>WooperOutcompeted and forced to live further from Water. Old dex entries mention it had poisonous skin.
>QwilfishTougher Hisuian only variety
>SneaselForced to adapt to mountain life and chilled out, losing Dark. Poison type comes out of nowhere though honestly
