Sonído

is a high-speed movement technique of the Arrancar. It is equivalent to the Shinigami's Shunpo and the Quincy's Hirenkyaku, which are roughly equal in terms of speed.

Description
While somewhat similar to Hohō in regards to function and speed, Sonído appears to be more instinctual, seemingly requiring no previous knowledge to perform. It produces a different sound; rather than the swishing or sometimes silent Shunpo of the Shinigami, Sonído makes a booming or static noise. Though the technique is exhibited by most Arrancar, the proficiency with which it can be performed is limited only by the individual, with Zommari Rureaux possessing the self-proclaimed fastest Sonído among the Espada. However, it is unknown if such claims are true, given that Zommari was outranked by six Espada of higher power, with Coyote Starrk in particular being able to cover tremendous distances at such speed that his Sonído seemed akin to teleportation. Starrk's use is notable for the fact that he simply appears solidly instead of shimmering momentarily like other Sonído users.
