Yammy
Bleach creator Tite Kubo uses many Spanish motifs for hollows and their variants.
Overview
Each Bleach human character consists of a body animated by a spirit identical in appearance. In the unusual event that a spirit is separated from his or her living body, it is possible to see a connective structure known as the chain of fate (因果の鎖 ,inga no kusari?), which attaches the spirit to its body and allows it to return to it.
When a human dies or the chain of fate is broken by force, the spirit cannot come back and becomes known as a plus (whole in the English translation). If the plus has many regrets, or strong emotional connections to a location, object, person, etc.
After some time, his/her emotions will eventually corrupt and gain control over the soul, which transforms into a hollow. Additionally, a broken chain of fate can eventually corrode completely, which also leads to the transformation into a hollow.
It is also possible for a spirit to use his/her abilities as a Soul Reaper to avoid turning into a hollow, instead becoming a visored.
Once a plus becomes a hollow, it gains a monster-like appearance, a skull-like mask, a large hole somewhere through its body, and an animalistic level of intelligence. Hollows crave other human souls, living or dead, to eat in an attempt to fill the void left in their hearts, starting with the souls of the people that they had loved the most in their past lives. Additionally, some hollows consume other hollows, eventually evolving into menos.
The hollows reside in the desert world of Hueco Mundo when not scouring the human world for souls to consume.
As hollows evolve, they gain access to unique skills and abilities, fueled by the souls they have consumed. The most common of these abilities is cero (虚閃（セロ） ,sero?, Japanese for "hollow flash," Spanish for "zero," called "doom blast" in the Viz manga), a high-powered energy blast that can be fired from various body parts, such as the mouth or hand.
If a hollow has its mask removed, it becomes an arrancar, and gains additional abilities and a more humanoid appearance.
There are two main duties of the Soul Reapers when dealing with hollows: to perform a ritual known as a soul burial (魂葬 (こんそう) ,konsō?) on pluses before they become hollows, and to slay hollows to purify their souls of all sins committed while in that form, so that they become pluses once again. When either of these duties are fulfilled, the plus goes to Soul Society.
Menos
Menos (メノス ,menosu?, Spanish for "minus" or "less") hollows have an unusually strong thirst for souls, which leads them to consume other hollows and evolve into a stronger state of being. Within the menos, there are three levels of evolution, each with superior strength, speed, and intelligence compared to its previous form.
The first of these is the gillian (最下大虚（ギリアン） ,girian?, Japanese for "least of the great hollows"), which is large and powerful, but possesses very little intelligence and no individuality as result of the merging of hundreds of hollows. From the adjuchas state, some have the potential to evolve into vasto lorde (最上大虚（ヴァストローデ） ,vasuto rōde?, Japanese for "great king of the hollows", Spanish for "vast", pseudo-Spanish "lord").
Vasto lorde are more humanoid in size and appearance and possess battle strength comparable or superior to a Soul Reaper captain, to the point where captain Tōshirō Hitsugaya speculates that Soul Society would be doomed if Sōsuke Aizen managed to get ten vasto lorde under his command.
Arrancar
Arrancar (破面（アランカル） ,arankaru?, Japanese for "broken mask", Spanish for "to tear off") are hollows that have had their masks almost completely removed and--through this process--gained the powers of a Soul Reaper, a more humanoid appearance, as well as strength, speed, and intelligence beyond the level of a normal hollow.
In addition to those improvements, arrancar also gain hierro (鋼皮 (イエロ) ,iero?, Japanese for "steel skin", Spanish for "iron"), skin so hard that it allows them to fight against sword-wielding opponents bare-handed, but is by no means impenetrable. In order to travel at extremely high speeds across short distances, arrancar use a technique known as sonido (響転（ソニード） ,sonīdo?, Japanese for "transfer effects", Spanish for "sound").
Unlike Soul Reapers, whose zanpakutō are manifestations of their owner's soul, arrancar's zanpakutō are manifestations of their former hollow selves. With occasional exceptions, an arrancar's zanpakutō resembles a regular sword in its sealed state.
When released through a process called resurrección (帰刃（レスレクシオン） ,resurekushion?, Japanese for "returning blade," Spanish for "resurrection"), part of their original hollow form is restored, changing their appearance, giving them greater strength, and granting them access to their original abilities.
Arrancar become major antagonists during the second part of the series as they start being led by Sōsuke Aizen, who uses the Hōgyoku to create and perfect the arrancar. They are ranked in order of their strength and have their respective number tattooed somewhere on their body as proof of their superiority.
What remains of his hollow mask is the jawbone, which rests on his chin. Yammy relies primarily on his brute strength and cero blasts in battle, taking little interest in using his sword until he is overpowered.
It affects a wide area, but any individual with even slight spiritual power is able to resist it to some degree. When he releases, his size increases dramatically, and the "1" on his ranking tattoo flakes away, leaving his rank to be 0.
Yammy is one of the first Arrancar introduced, appearing alongside Ulquiorra when they come to the physical world looking for Ichigo Kurosaki.
He reappears while Ichigo is battling Ulquiorra in the throne room of Las Noches. Lilinette (リリネット ,Ririnetto?), his young female fracción, typically shows the concern that Stark does not. When he is shown to be serious, however, his personality changes completely; he comes off as reluctant but nonetheless willing to do what needs to be done to complete the task at hand.
He also appears to be uninterested in fighting, going as far as to suggest that he and Shunsui Kyōraku pretend to fight until everyone else is finished. He is a stout, older and grumpy arrancar, and the remnant of his mask takes the form of a five-pointed crown.
Despite being the second Espada he exploits Stark's indifference by assuming leadership over the arrancar once Aizen is trapped, giving orders from a skull-adorned throne, even instructing Halibel to "not underestimate him". Only after all his fracción are dead does he engage in battle against Soi Fon personally.
Barragan has six male fracción; Charlotte Cuuhlhourne (シャルロッテ・クールホーン ,Sharurotte Kūruhōn?), Abirama Redder (アビラマ・レッダー ,Abirama Reddā?), Findore Carias (フィンドール・キャリアス ,Findōru Kyariasu?), Choe Neng Poww (チーノン・ポウ ,Chīnon Pō?), Ggio Vega (ジオ·ヴェガ ,Jio Vega?), and Nirgge Parduoc (ニルゲ・パルドゥック ,Niruge Parudukku?).
Halibel
Voiced by: Megumi Ogata
Halibel (ハリベル ,Hariberu?) is the Tercera Espada, signified by the "3" tattooed on the inside of her right breast, she is also the only current female Espada. She is very calm and rarely speaks, and when she does it's fairly serious, such as when she tells her three female fracción Apache (アパッチ ,Apacchi?), Mila Rose (ミラ・ローズ ,Mira Rōzu?), and Sun-Sun (スンスン ,Sunsun?) that being afraid of an Espada's released form is a natural reaction.
She carries her zanpakutō horizontally behind her shoulders; the sword itself is notably broad and short compared to those of other Espada, and the inner portion has been removed, leaving only the "outline" of the sword. The sword can create 'ribbons' of energy from the empty inner portion to be used in combat.
In the manga, her breasts are partially shown; however in the anime they are completely covered.
Neliel Tu Oderschvank
Nel in her child and adult forms.
Voiced by: Tomoko Kaneda
Neliel Tu Oderschvank (ネリエル・トゥ・オーデルシュヴァンク ,Nerieru Tu Ōderushuvanku?), commonly known as Nel Tu (ネル・トゥ ,Neru Tu?), is a good-natured, child-like arrancar when first introduced. Nel's true form is that of a fully-grown woman, her mask appearing less cartoonish with a pair of curved horns.
When Nel runs into Nnoitra years later as he begins to torture Ichigo, she turns into her adult form with her memories restored. The lance moves at high speed and rotates extremely fast, drilling through anything it hits.
Ulquiorra Cifer
Voiced by: Daisuke Namikawa
Ulquiorra Cifer (ウルキオラ・シファー ,Urukiora Shifā?) is the Cuarta Espada, signified by the "4" tattooed to his chest.
He will attack his comrades to get them to pay attention to him, and deems anyone he does not find of particular interest to be "trash" and therefore expendable. The remainder of Ulquiorra's hollow mask forms a broken helmet with a curved horn and covers the left half of his head. His hollow hole has moved since his first appearance; when first introduced it is at the base of his neck, but in later appearances it has been moved onto his chest.
In battle, Grimmjow Jeagerjaques notes that Ulquiorra tends to stab opponents in the chest, the same location as his hollow hole, whenever he is particularly interested in a battle, though it is unclear if Ulquiorra is conscious of this habit. He is very analytical; he almost accurately theorizes the means behind Orihime Inoue's abilities, and recognizes that Ichigo Kurosaki's power constantly fluctuates between comparatively very weak and stronger than his own. He also seems to refrain from killing a person unless necessary, twice sparing Ichigo and proclaiming he would not harm Orihime because he had not been ordered to.
His hollow helmet centers atop his head, sporting two large horns, and his arrancar uniform appears more form fitting at the top, becoming robe-like towards the bottom. Additionally, Ulquiorra is apparently unique among the Espada in that he has a second release; Resurrección Segunda Etapa (Spanish for "resurrection second stage"). He becomes more muscular with clawed hands and feet, the whites of his eyes turn green, and his helmet is replaced with elongated horns, effectively removing his mask. Ulquiorra's arms and legs from the hip down are covered in black fur, and he gains a long thin prehensile tail. In both forms he can create long "lances" of energy called Lanza del Relámpago (雷霆の 槍(ラソサ・デル・レランパーゴ) ,ransa deru reranpāgo?, Japanese and Spanish for ”lance of the lightning”), and when thrown can cause an explosion. Ulquiorra seems unfamiliar with the technique when he uses it in his second release state, unexpectedly missing Ichigo with his first one, however, to compensate, he can produce more should his first miss the target.
He wears a large eye-patch that covers most of the left side of his face, as well as the remnants of his hollow mask (a small set of jawbones and teeth) and his hollow hole, both located around his left eye socket. Grimmjow has an overly violent lust for battle, always seeking out the strongest opponent in a given area and he is very confident in his abilities, believing himself to be equal to, or even stronger than the fourth Espada, Ulquiorra Cifer. Though he shows little regard for his allies or anyone who would get in his way, Grimmjow has some sense of honor; he rescues Orihime from two arrancar torturing her in return for healing his arm, and first has Ichigo's wounds healed before their final rematch. Grimmjow hates being looked down on, becoming infuriated beyond consolation when he feels that someone does so and has stated that he will readily crush anyone who looks down on him, be it friend or foe.
These hollows later became his fracción: Shawlong Qufang (シャウロン・クーファン ,Shauron Kūfan?), Edorad Leones (エドラド・リオネス ,Edorado Rionesu?), Ilfort Grantz (イールフォルト・グランツ ,Īruforuto Gurantsu?), D-Roy Linker (ディ・ロイ・リンカー ,Di Roi Rinkā?) and Nakim Greendina (ナキーム・グリンディーナ ,Nakīmu Gurindīna?).
When his zanpakutō, Pantera (豹王（パンテラ） ?, Spanish for "panther," Japanese for "panther king") is released he regains some of his former feline characteristics such as jagged teeth, feline ears, clawed hands and feet, and a tail that can be used as a powerful whip. This state augments his speed drastically and gives him animal-like agility and movements to match. Luppi's zanpakutō is Trepadora (蔦嬢（トレパドーラ） ,Torepadōra?, Spanish for "climber," Japanese for "ivy girl"), and in his released state eight tendrils sprout from a carapace mounted on his back, which he can control independently to combat a group. The tentacles can also grow spikes to cause additional damage.
His zanpakutō is Brujería (呪眼僧伽（ブルヘリア） ,Buruheria?, Spanish for "witchcraft," Japanese for "sangha of bewitching eyes") and in his released state he gains a total of fifty eyes, each of which can be used to gain complete control of whatever or whoever they look upon; this technique is called Amor (愛（アモール） ,Amōru?, Spanish and Japanese for "Love"). He thinks poorly of non-hollows, and hopes that Sōsuke Aizen will someday eliminate all entities that aren't hollows.
Szayel has a variety of methods for analyzing an opponent's abilities, such as studying the damage done to their former opponents. The remains of his hollow mask take the form of rectangular-framed glasses.
Szayel's zanpakutō is called Fornicarás (邪淫妃（フォルニカラス） ,Forunikarasu?, Japanese for "lewd concubine," Spanish for "You will fornicate"), and, in his released state, he grows two pairs of thin wings, and his lower body transforms into a flock of long tentacles. He can shoot a stream of blood-like liquid from his body and if even one droplet comes into contact with an opponent a doppelganger of them is created that Szayel can control to use their abilities against them.
Any damage done to the dolls' internal organs is done to the original, debilitating them from the inside. The last of his many abilities, known as Gabriel (受胎告知（ガブリエール） ,Gaburiēru?, Japanese for "the Annunciation"), allows him to be reborn if he is injured beyond repair by impregnating an enemy and absorbing their spirit particles, turning them into his own and killing the victim in the process.
Szayel engages Renji Abarai and Uryū Ishida in a battle, during the course of which he nullifies each of their abilities and damages them enough to be in a non-combative state.
After Mayuri kills him Szayel reconstitutes himself inside of Nemu Kurotsuchi, ingesting a large dosage of an experimental drug stored in Nemu's body in the process. He has an unusual glass capsule filled with red liquid and two floating masks in place of a head, which he usually covers with a tall white mask.
In addition, two beak-like extensions jut out from these cyclones, which are used to execute long-range strikes, though Dordonii is also capable of manifesting many more if the need arises.
Cirucci Thunderwitch
Voiced by: Hōko Kuwashima
Cirucci Thunderwitch (チルッチ・サンダーウィッチ ,Chiruchi Sandāwicchi?) has an appearance similar to a gothic lolita; her outfit consists of a frilly dress, large poofy sleeves that cut off at her shoulder, short purple-colored hair, teardrop markings on each cheek, and knee-high boots. Retsu Unohana intervenes before they can be killed, and heals Chad and the Arrancar's wounds after Rudobone decides to leave and not attack any of them.

The following are those arrancar that have never received a position as an Espada.
Grand Fisher
Voiced by: Chafūrin (Japanese), Paul St.
After Ichigo is able to defeat Grand Fisher in battle he is converted into an imperfect arrancar, giving his hollow-form a more humanoid appearance. He shows some hostility during this instance, firing a retaliatory bala energy blast toward Kisuke Urahara at one point, but quickly reverts back to his regular state after doing so.
