Powers & Abilities Like Shinigami, Arrancar have a multitude of combat skills and abilities, some of which are similar to those of the former, and some of which are variations on ordinary Hollow powers.
Bala (虚弾 (バラ), bara; Spanish for "Bullet," Japanese for "Hollow Bullet") Bala is an Arrancar alternative to Cero. The technique hardens the user's Spiritual Pressure and fires it like a bullet. Although it is weaker than a normal Cero, it moves about twenty times faster and can be fired at a much higher rate, but the damage is much the same. Stronger Arrancar can also fire a more powerful Bala, while retaining its twenty-fold speed.
Cero (虚閃 (セロ), sero; Spanish for "Zero," Japanese for "Hollow Flash," "Doom Blast" in the Viz translation) are high-powered energy blasts that can be fired from various body parts, such as mouth, tongue, hand or fingers. Only Gillians, Adjuchas, Arrancar, and the Vizard have so far been shown to use Cero attacks, and it appears that stronger entities can use it more efficiently. Various Arrancar and Hollow characters display variants of the technique, such as the Espada-exclusive Gran Rey Cero, the Cero Oscuras that Ulquiorra Cifer can use only in his released form, as well as the Cero Sincrético performed by Pesche Guatiche and Dondochakka Bilstin.
Garganta (黒腔 (ガルガンタ), garuganta; Spanish for "Throat," Japanese for "Black Cavity") is how Arrancar and Menos-class Hollows move to and from Hueco Mundo. Kaname Tōsen, Kisuke Urahara and Mayuri Kurotsuchi have also demonstrated the ability to use the technique. It literally tears open the dimensional fabric separating the worlds, revealing a tunnel of whirling, torrential energy that must be focused and solidified to create a discernible pathway.
Hierro (鋼皮 (イエロ), iero; Spanish for "Iron," Japanese for "Steel Skin") refers to the hardened skin of the Arrancar, which is a result of their compressed spiritual power. While their skin is strong enough to block even released Zanpakutō bare-handed, it is by no means impenetrable. Stronger Arrancar generally have proportionally stronger skin than usual.
Negación (反膜 (ネガシオン), negashion; Spanish for "Negation," Japanese for "Anti-Membrane") are energy fields are used 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. 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") meant to simulate Negación fields, which are used to punish their subordinates 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 is being used as intended. More powerful Arrancar, namely the Espada themselves, can escape given enough time.
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.
Sonído (響転 (ソニード), sonīdo; Spanish for "Sound," Japanese for "Sound Ceremony") is the Arrancar equivalent of the Shinigami Flash Steps and the Quincy Hirenkyaku; it allows the user to travel at incredibly high speeds for short distances. Use of Sonído is punctuated by a brief static sound, in contrast to the "swish" sound caused by Flash Steps.
