Flukefey

"Youngest of its species. Its body is composed of teeth, wings and stomach. Seems to want to latch onto any living thing that comes by with its sharp little teeth. It will leave its cousins alone though, so it isn't completely mindless."

Flukefeys are enemies in Hollow Knight. The youngest of the Flukes, these flying creatures use their sharp teeth to latch onto any living thing.

Behaviour and Tactics
Floats passively until disturbed. When engaged, it reveals its fangs and dives at the Knight in a parabolic arcing motion, dealing damage on contact. They are extremely fast and frantic, making them hard to fend off despite their low health. Because of this, it is advised to stand still and let them come closer themselves, as their seemingly unpredictable movement makes it hard to pursue them.

The Longnail, Mark of Pride, and Quick Slash Charms can be quite useful against them. After two Nail upgrades, they can be killed in one hit, making it significantly easier to deal with them.

Location
Flukefeys can be found only in the central-west part of the Royal Waterways. They can also be spawned by Flukemarm.
