Almost any Humanoid pokemon (Lopunny *shudder*). Most poison-types (muk, Quilfish *Human was poisoned-Human died*). Anything that has a super high body temperature (slugma *Ouch that burns*). Almost all ghost types (Shedninja, Ghastly *Get away from my soul you demon! O_O*). Girafarig (That evil tail...). Large bug types (Ariados, *Creepy crawlies make me uncomfortable*). Meancing snakes (Arbok, Seviper *Mind the fangs*).
I think that cover most of them... '_'
