绿宝石Over the course of evolution, its hind legs turned into wings. By alternately resting its front and rear wings, it can fly all day without having to stop.
蓝宝石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.
红宝石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.
水晶As a result of its pursuit of faster, yet more silent flight, a new set of wings grew on its hind legs.
