so you just got out of the world's best cave, and kicked the (surprisingly toned) ass of the local gym leader, now it's time to explore that mysterious tower thing.
which is apparently haunted by aliens, or something. With Christmas lights for hands.
No, it's not making any sense to me, either. Nor is the name. Just try even saying it - Elgyem. Your mouth gets all contorted and shit, twisting around like a Mario Kart track. Not even once, Eglyem. not even once.
He's one of those weird cases where the design looks unlike anything earthly at all, but it's supposed to be strange and bizarre. Hell, Elgyem would make a decent stand (probably an Act 1 version). But if they were trying to create an "alien" Pokemon, then why'd they use basically NOTHING of accepted generic-alien stereotypes? He's got a big head, but he isn't green, and his eyes aren't black, nor nearly large enough. He's got a tail, and again a freaking nativity scene shining from each hand. He's not even like Japan's idea of aliens, which is pretty much just squids, but with more tentacles. Like the invaders from Metal Slug.
It doesn't help that Elgyem is of the same mold as every other Psychic-type in this game - slow, with high Sp. Attack. Except without any sort of good defensive ability. Go back to space, dipshit. We don't want your kind here.
