>>50888598Also it's somewhat implied that the Hisui starters (Oshawott, Rowlet, and Cyndaquil) were introduced via spacetime rifts and began nesting in the region, but eventually were wiped out, either due to competition (like the Cyndaquil line living in a biome full of ground, rock, and water types), or improper habitats, (Rowlet in a cold mountainous area, which the dex states it is not used living to, and Oshawott being in a frozen tundra when the evolution line is based on oceanic animals). Of course you could argue Rowlet had a better chance than the other two due to adapting according to the dex, and the evolution being fully acclimated, but even then wild final evos are rare and Rowlet were likely wiped out by Johtonian Sneasel eventually, if not by other factors
I wonder if there are any other cases like this.
