Sonído

is a technique mainly used by Arrancar which allows them to move at extreme speeds, making it equivalent to the Hohō (or Flash Steps as they are called in the English Dub) that Shinigami use and the Hirenkyaku that Quincy use. While somewhat similar to Hohō, Sonído appears to be more instinctual than Hohō, requiring no previous knowledge to perform. It also makes a different sound; rather than the swishing or sometimes silent Flash Step of the Shinigami, Sonído makes a booming or static sound.
