Crobat

Crobat is the final evolution of Zubat, evolving from Golbat when it reaches a high level of friendship—making it notable as one of the early friendship-based evolutions introduced in the Generation II games. Its defining trait is that its hind legs have developed into a second pair of wings, granting it four wings total and exceptional, silent flight that lets it dart through cramped caves without slowing down. A Poison/Flying-type known for its high speed, Crobat preys on the blood of other creatures while in flight and is associated with caves and nocturnal habitats throughout the Pokemon world.

The Japanese name クロバット (Kurobatto) is a blend of クロ (kuro, meaning 'black') and the English word 'bat,' alluding to its dark coloration and bat-like form. The English name 'Crobat' is essentially a near-direct adaptation of the Japanese, combining a 'Cr-' element (often interpreted as evoking 'cross' for its crossed wing-limbs, or simply carrying over the 'kuro' sound) with 'bat.' Both names ultimately center on the bat motif that defines the species.
