Stinger

The Stinger is a creature featured in Made in Abyss: Binary Star Falling into Darkness.

Description
Stingers appear to be a cross between a bird and a bug.

They flap their wings so fast they can't be seen as these creatures glide and they will fly at an uncanny speed in pursuit of prey.

The part that looks like a beak is actually a very sharp horn which can pierce as well as cut flesh.

They are unable to change directions while rushing at their prey, which may cause them to crash into trees or rocks.

They often get eaten by other creatures while stuck in this way.
