Incubus

Incubi were followers of the White Witch. They are described to show the appearance of man or woman, and the appearance of a bat, mostly half-human, half-bat. Similar to vampires, Incubi enjoy to prey at night, instead of the day. They get blinded from the sun to easily, and sleep during the day. It's unknown where they live in Narnia, but its possible that these creatures live in dark caves, like the bats. They are able to fly very fast with their large bat-wings.

The Incubi first appeared in The Lion, the Witch, and the Wardrobe where they gathered as loyal followers to the White Witch. They were present in the sacrifice where they gather with all the dark creatures to watch Aslan die. Incubi were never present in the battle since they never go out in the daytime.
