Here's a little guy I've wanted to draw for the longest time - Aarei from the beta versions of Ruby and Sapphire, which I've decided to localize as Eeriel and heavily headcanon. Nothing is truly known about it other than the fact that it was cut due to being too 'serious/dramatic' for a Pokémon concept. The common consensus is that it's based on a selkie, a mermaid and perhaps a dog? From the moment I saw it I fell in love, it's got such a sad look on its face and I feel so sorry for it.
One of Corphish's Pokédex entries says that they're not native to Hoenn and were imported as pets, with theories that it evolves into Crawdaunt to phisically mimic Sharpedo and protect itself from predators. For that reason, I created a chain wherein Eeriel are preyed upon by Sharpedo, Eeriel hunt Corphish inspired by the real life crab-eater seal (which doesn't actually eat crabs, but it's a reference) and, in turn, Corphish evolves into Crawdaunt and adopts the Dark type to defend itself against Eeriel by mimicking its natural predator.
Its a very sad, skittish Pokémon, probably most commonly found around the Abandoned Ship.
