Crobat

Crobat is a large, bat-like Pokemon discovered in Generation II. It is revealed to be the evolved form of Golbat. This can be done when a trainer maximizes its friendship with their Golbat. Crobat is a dual Poison/Flying type Pokemon. It is the true final evolutionary form of Zubat.

If this Pokémon is flying by fluttering only a pair of wings on either the forelegs or hind legs, it's proof that Crobat has been flying a long distance. It switches the wings it uses if it is tired.

Crobat sneaks up on its intended prey using wings that barely make a sound. This Pokémon rests by hanging on a tree branch with its rear legs that serve as wings.

Ultimate Story

Falco owns a Crobat.

Zelda also owns a Crobat. Like most of her Pokemon, it is a female.

Phase 4

Lydia owns one as part of her Johto Team, which she captured early on her Johto region toruney as a Zubat. Seeing potential in just a hated pokemon she took in Zubat as her 2nd pokemon at Dark Cave which payed off due to it's loyalty and determination to please it's trainer.
