Even though I'm on Team Lunatea, you can't argue with me that Phantomile didn't have creepier stuff. I mean, there were the eclipse monsters, Joka's eclipsed form, NAHATOMB EATING YOU ALIVE AND FORCING YOU TO FIGHT OFF A SERIOUSLY CREEPY FACE THAT LOOKED WAY TOO MUCH LIKE SPIRITOMB, EXCEPT IT WAS BEFORE SINNOH WAS EVER A THING, SO IT'S MORE LIKE SPIRITOMB COPIED NAHATOMB'S CREEPINESS AND OH MY GOD THEY EVEN HAVE SIMILAIR NAMES PLEASE HOLD ME
I have to say that Cursed Leorina is pretty creepy. I mean, it's all demonic-looking and malformed, ya know? Also, it's like a spider, and spiders are kinda creepy. Except for Pikmin's Man-at-legs, which is instead awesome, but that's a discussion for another day.
