Vibrava

“To make prey faint, VIBRAVA generates ultrasonic waves by vigorously making its two wings vibrate. This POKéMON’s ultrasonic waves are so powerful, they can bring on headaches in people.”

— Pokémon Ruby

“VIBRAVA’s wings have not yet completed the process of growing. Rather than flying long distances, they are more useful for generating ultrasonic waves by vibrating.”

— Pokémon Sapphire

“It looses ultrasonic waves by rubbing its wings together. Since a VIBRAVA’s wings are still in the process of growing, it can only fly short distances.”

— Pokémon Emerald
