And here is a reference for Zaron. Again, his backstory is that he's a Raichu whose evolution went a bit off thanks to a defective thunderstone, leaving his belly Pikachu-coloured. This, in turn, has filled him with a superiority complex wherein he believes all Pikachu belong in his belly. This is based on his latest design, which features his unique tail and tail-storage areas~ The sack at the end of his tail emits a sweet scent no one can resist, so any unlucky Pikachu rushes on in to smell the smell. Whereupon they're pumped down the tail, all the way into the inner-storage pouch within Zaron, beneath his stomach, where they're kept until Zaron feels hungry~
