|Universe||Miss Peregrine's Home for Peculiar Kids|
Hollowgasts are creatures from the Miss Peregrine's Home for Peculiar Children series.
They were originally normal humans, but transformed after they underwent a botched experiment attempting to render the subjects immortal. As a result, they are monstrous hideous beasts who must prey on eyeballs of peculiars in an attempt to turn back into humans.
Hollowgasts possessed the peculiarity of being invisible. Only certain individuals could see them, including Abe and Jake. They were required to feast on eyeballs of people who were also 'strange' to regain visibility and their regular human features.
- Despite the belief that they only prey on peculiar individuals, they are also seen to demonstrate extreme aggression, for they also devour the eyeballs from sheep.
