Grypheldis

Black: It makes a nest out of bones it finds. It grabs weakened prey in its talons and hauls it to its nest of bones.

White +2: Watching from the sky, they swoop to strike weakened Pokémon on the ground. They decorate themselves with bones.

Black 2 +3: They fly in circles around the sky. When they spot prey, they attack and carry it back to their nest with ease.

Sun: They adorn themselves beautifully with bones. This is supposedly an effort to attract males, but no male Mandibuzz have ever been found.

Moon: It circles in the sky, keeping a keen eye out for Pokémon in a weakened state. Its choicest food is Cubone.

Ultra Sun: It skillfully arranges the bones of its prey to construct its nest. Most of the bones are Cubone.

Ultra Moon: It’s always searching for food for Vullaby. When it finds a weak Pokémon, Mandibuzz swoops it right off to its nest.

Sword: Although it’s a bit of a ruffian, this Pokémon will take lost Vullaby under its wing and care for them till they’re ready to leave the nest.

Shield: They adorn themselves with bones. There seem to be fashion trends among them, as different bones come into and fall out of popularity.
