Hybyhy

Hybyhy is a Dark-type Pokémon introduced in Generation Neo-I.

It is not known to evolve into or from any other Pokémon.

Biology
Hybyhy is a tall, bipedal feline Pokémon. Its body is covered head to toe with dark black fur, with only its curious eyes peeking out. Hybyhy's most notable feature is its tendency to hide behind any object that can conceal it, whether this be trees, buildings, rocks, etc., which is evident in its Ability.

Triva
Hybyhy may be based off of the North American legendary critter The Hidebehind. It also takes inspiration from hyenas and their laughter.

Hybyhy may be a corruption of hidebehind as well as stylistically reminiscent of a hyena's laugh (hehehe).
