When I say "worst," I don't mean "monsters that could kick the most ass" or anything like that. I mean, "Who the fuck came up with this stupid motherfucking thing?"
Take the creature posted as the pic of this thread. It is a shirime, otherwise known as the anus eye.
Long ago, a samurai was walking at night down the road to KyÅto, when he heard someone calling out for him to wait. "Who's there?!" he asked nervously, only to turn around and find a man stripping off his clothes and pointing his bare buttocks at the flabbergasted traveler. As if this weren't traumatizing enough, a huge glittering eye then opened up where the strange man's anus should have been.
The samurai ran away screaming, and this obscene apparition was never seen again.
The haiku poet and artist Buson liked this naughty creature enough to include it among his many paintings of yÅkai.

A guy's anus has been replaced with an eye? Why? Why would you think of that shit? How is that even scary? If I saw a shirime, I'd run away, but out of disgust, not fear. That thing's sick.
Please, share the creatures you have heard of that made you think, "¿Por qué?"
