Crobat

Crobat (クロバット Kurobatto) is a /-Type Bat like Pokémon which has gained vastly enhanced flying performance by having a new pair of wings. A common misconception is that Golbat's legs turns into wings when evolves, but it actually isn't, as shown by Crobat's Back Sprite in R/S/E. It is the final evolution of Zubat and is notable for it's very high speed stat. Evolution from Golbat requires it to be very happy when it gains a level.
