Name: Hierro
Type: Racial
Description: The user's Reiryoku condenses, creating a steel-hard skin strong enough to block a Zanpakutō. This allows users to confront some of the sword-wielding Shinigami barehanded. While this technique is exhibited by all Arrancar to some degree, the strength of an individual's Hierro is entirely proportional to the potency of their Reiryoku.
Name: Cero
Power Rank: MP
Description: Cero (虚閃 (セロ), Sero; Spanish for "Zero", Japanese for "Hollow Flash", Doom Blast in the Viz translation, literally "Empty Disaster") is an attack used by Menos, Arrancar, and Visored. The practitioner fires a powerful blast of concentrated spiritual energy at the target. While in most cases it is fired from the mouth, some Arrancar and Visored can fire Cero from their hands, fingers, and other parts of their bodies. This often requires the user to take on a specific pose, with Coyote Starrk being the only exception. The power, force, speed, and blast area of the Cero is dependent on the strength, spiritual power, and sometimes skill of the user (i.e., the stronger the user, the stronger the attack), and there are some Arrancar who have come up with their own variation of Cero. The charging and firing time for Cero varies greatly, from charging relatively fast to firing it to instantaneously firing one without much charging. Despite the damage it can cause at long range distances, Love Aikawa states the damage which a Cero causes as an explosion is more dangerous when used at close range.
Name: Bala
Power Rank: RM
Description: Bala (虚弾 (バラ), bara; Spanish for "Bullet", Japanese for "Hollow Bullet") is an Arrancar-exclusive offensive technique. While similar in function to a Cero, a Bala is not nearly as powerful, but, thanks to its composition, its speed is 20 times faster, allowing it to be fired in quick succession.
Name: Vagido
Power Rank: MP
Description: Vagido (ヴァヒード, vahīdo; Spanish for "Child's Wail") is a technique used by the Arrancar, Wonderweiss Margela. After a short intake of breath, Wonderweiss unleashes a deafening, banshee-like cry, creating a powerful shock wave. The power of the shock wave is tied to Wonderweiss emotional state at the moment of usage; the stronger he feels, the stronger the attack, to a point.
Name: Imperfect Sonido
Power Rank: MP
Description: Sonído (響転 (ソニード), Sonīdo; Spanish for "Sound", Japanese for "Sound Ceremony") is a high-speed movement technique of the Arrancar. It is equivalent to the Shinigami's Shunpo, which is roughly equal in terms of speed, and the Quincy's Hirenkyaku. 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. Using Sonido, Wonderweiss is able to cover large areas very quickly; however his range is limited by his age and overall power. He can only cover roughly 300 yards with each use of Sonido, and must wait for a period of time between each usage tied to the distance he travels; with 100 yards of travel equaling 1 post of wait time.
