Other Skills Of Hueco Mundo

Bala (虚弾 (バラ), bara; Spanish for "Bullet", Japanese for "Hollow Bullet") is an Arrancar-exclusive technique that hardens the user's Reiatsu and releases it like a swift blast of spiritual energy. While the technique is not nearly as powerful as a Cero, its speed is 20 times faster and allows for it to be fired in quick repetition. A Bala's speed and power varies with the Arrancar using it; while the power of Yammy's Bala is equated with a powerful punch, Ulquiorra's Bala is capable of blasting large holes in enemies.

Sonído (響転 (ソニード), Sonīdo; Spanish for "Sound", Japanese for "Sound Ceremony") is a technique used by Arrancar which allows them to move at extreme speeds, making it highly similar to the Hohō (or Flash Steps as they are called in the English Dub) that Shinigami 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.

Variations Gemelos Sonído (双児響転 (ヘメロス・ソニード), Hemerosu Sonīdo; Spanish for "Sound Twins", Japanese for "Sweeping Sound Ceremony"): Zommari Leroux is the only Arrancar shown to have been able to use this technique and it allows him to create clone-like afterimages of himself. Up to five clones can be created using this technique. Because of this, Zommari claims that he is the fastest


Hierro (鋼皮 (イエロ), iero; Spanish for "Iron," Japanese for "Steel Skin") is an Arrancar technique in which the user's reiryoku condenses, creating a steel-hard skin strong enough to block a Zanpakutō. This also allows them to fight some of the sword-wielding Shinigami barehanded.

The strength of Arrancars' Hierro depends on their spiritual power; While Hierro can block even released Zanpakutō, Kenpachi Zaraki discovered that he could cut Nnoitra's by adapting to the latter's Reiatsu.

The technique is exclusive to Arrancar, and it has yet to be seen if the Vizard are capable of using Hierro during their Hollowfication. Shinigami have been shown using reiatsu to block or lessen the blows of Zanpakutō, such as when Ichigo Kurosaki used his reiatsu to momentarily stun Shūsuke Amagai during their battle. Also, when Ichigo and Kenpachi Zaraki first fought, Ichigo failed to injure Kenpachi even after he offered Ichigo an opportunity to cut him. However, this ability cannot be done to the same extent as this Arrancar technique.

Ichigo, in his half-transformed Hollow state, exhibited a variation of this technique where, after enduring several injuries inflicted upon him by the Vizard, displayed an ability to regenerate his wounds with a bone-like carapaces that appears to be just as resistant as the standard Hierro, if not more so.

Negación (反膜 (ネガシオン), Negashion; Spanish for "Negation," Japanese for "Counter-Membrane") is the term used for the fields used by Hollows to rescue fellow Hollows. Only the Gillian-class Menos have shown the ability to use it. Negación fields surround a target in a square beam of light that isolates the target from the dimension they are currently in, making it impossible to harm them. The field then pulls the target towards the Menos that created the field.


**Menos Gillian
Kaname and Gin saved by Negación All Gillian-class Menos can use Negación, but only if the target is outside of Hueco Mundo (such as Living World, Soul Society, etc.) They only use the technique to aid their comrades or fellow Hollow, which during Aizen's escape, were Kaname Tōsen, Gin Ichimaru and Sōsuke Aizen. General Yamamoto stated that once that beam of light surrounded them, it was over, because there was no way to reach them as the Negación field is impenetrable.

Espada Caja Negación
Caja Negación binding Ulquiorra Espada have a special cube-shaped device called Caja Negación (反膜の匪 (カハ・ネガシオン), kaha negashion; Spanish for "Negation Box," Japanese for "Anti-Membrane of Negation") (Caja de Negación in the English dub) meant to simulate Negación fields, which are used to punish their Fracción, if necessary. The cube, when used on a subject, traps them in an alternate dimension from which there is no escape; however, this assumes it's being used as intended. More powerful Arrancar, namely the Espada themselves, can escape, given enough time. The only occurrence of this Negación field being used was when Grimmjow Jaegerjaquez trapped Ulquiorra Cifer with it.

Apparently, the small cube device must be placed in the Arrancar's Hollow hole, as during their battle, Grimmjow waited to use it until he could place it in Ulquiorra's chest.

Pesquisa (探査回路 (ペスキス), pesukisa; Spanish for "Inquiry," Japanese for "Probe Circuit") is the Arrancar equivalent of the Shinigami ability to sense Spiritual Pressure. It functions very similarly to sonar.

Resurrección (帰刃 (レスレクシオン), resurekushion; Spanish for "Resurrection," Japanese for "Returning Blade") Most Arrancar have the ability to seal their power within a Zanpakutō. Upon releasing their Zanpakutō, they gain all of their former unique Hollow abilities back, essentially 'resurrecting' their old selves. When using this ability, they essentially combine their human form and their Hollow form, incidentally increasing their power considerably. As another note, when an Arrancar uses his or her Resurrección, it heals all minor wounds.
