First Mission, Hollow Extermination

Gillian Class Hollow

Adjuchas Class Hollow

A vasto lorde will not be making an appearance.

There abilities:
* Soul-Body Separation: Two middle class hollow, Shrieker and Acidwire, have been shown using this ability, though presumably all Hollows have the ability. This technique allows a Hollow to forcibly extract a living spirit from his/her body. It is usually not used because Hollows tend to go after Pluses, who have no physical or living body to speak of. Acidwire used this on his younger sister, Orihime, so she could see and converse with him. Shrieker used it for more sinister means, causing the young boy Yūichi Shibata to be trapped within the body of a parakeet for three months while the Hollow chases him. The soul is still attached by the Chain of Fate and can be saved, but if it is broken (in Yūichi's case) then the soul can prevent the Encroachment so long as he/she is placed inside a soulless body or animal. It seems as though Shinigami have reverse engineered this ability, as shown with the Skull Symbol. It may or may not be possible that this ability could also extract a Shinigami from their Gigai, but this would obviously prove harmful to a Hollow.

* Acidic Touch: Many Hollows, like Shrieker and Acidwire, have displayed this ability, although Rukia implies that all Hollows possess this power. When a Hollow grabs a Human with their hands, the spot where the person was grabbed is shown to get burned as if acid were poured onto it. This was shown when Orihime was grabbed in the leg, and on the wound on Chad's back. These wounds seem to allow the Hollow's reiatsu to seep into the person, causing great pain to the victim. The wounds can heal if given enough time though, and it is unknown if this ability works on Shinigami or other spiritually powerful beings.

* Cero (虚閃 (セロ), sero; Spanish for "Zero", Japanese for "Hollow Flash", 'Doom Blast' in the Viz translation) is a highly-powerful and relatively-swift energy blast that can be fired from various body parts, such as mouth, tongue, hand or fingers. Only Menos, Arrancar, and Vizard have so far been shown to use Cero attacks, and it appears that stronger entities can use it more efficiently and forcefully. Cero also requires some time to be used effectively, so the enemy must be either not moving or busy with something else, or too badly wounded to even simply dodge it, with the exception of a few Cero techniques and users. Additionally, there exists quite a number of variations of Cero, which are usually unique to the Arrancar using it.

* Garganta (黒腔 (ガルガンタ), garuganta; Spanish for "Throat", Japanese for "Black Cavity") is how Hollows and Arrancar move to and from Hueco Mundo. Kaname Tōsen and Kisuke Urahara 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.

* Negación (反膜 (ネガシオン), negashion; Spanish for "Negation", Japanese for "Counter-Membrane") fields are used to rescue fellow Hollows. Only the Gillian-class Menos have shown the ability to use it. 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.

* High-Speed Regeneration is the ability that allows a Hollow to heal most injuries very quickly, with the exception of the destruction of the head or vital organs. Only Menos-class Hollows have demonstrated this ability. Ulquiorra states that most Arrancar gave up Regeneration for far greater strength.
