Welcome back!
Before we begin, I would like to thank u/DarkBlueAnt for the Lickitung art in the Thumbnail. I have no connection to them, but googled "unsettling Pokémon" and their beautiful work came up.
Also, I should get in front of this. I am aware this is weird, ranking Pokémon by their physical appearance but it's the only thing getting me through the workday.
Okay, let's begin.
