It's no secret that bats are often used for Creepy Awesome effect. They're tiny, rat-like and can fly—it's no wonder the Bat Out of Hell sends shivers down many a spine. But there's one more way to exaggerate the grotesque features of a bat.
They're already associated with blood-sucking and the undead, so why not go the extra mile and add a singular eye? Due to their body shape, this often gives off the illusion that you're being stared at by an eye with wings, and in some cases, the detached eye could be used for good potion-making. Expect animals like these to often be associated with villains or form Mooks, and in some cases, being literal Goddamned Bats.
These can become an Oculothorax when their body mass is more "eye" than "bat", but the line can be pretty unclear. Also a sub-trope of Cyclops.
If the character can summon/use more than one bat and they have dark powers, then it could be added to Barrage of Bats.
Compare Bloodsucking Bats for another inaccurate way of portraying bats. Contrast Blind Bats.
Don't be surprised if fans consider this an Ugly Cute.

- Played with with the Pokémon Woobat. It has a fluffy, circular body with a giant round circle in the middle of its face, which has a black, pupil-like center.
