List of Hollows in Bleach

Following Aizen's defeat, the arrancar survivors attempted to become their society before they conquered by the Quincy extremists known as the Wandenreich, with those captured either drafted as expandable foot soldiers or executed as monsters.

Hollows become stronger by eating other souls with the most successful who avoid being slain able to eventually evolve into formidable foes known as Menos (メノス, Menosu, Spanish for "minus") which are classified and divided into three succeeding stages.

After Ichigo's return from Soul Society, the hollow-based characters known as arrancar are introduced, with the basic hollows having lesser roles and rarely used as villains except in the anime side-story episodes.

In this form, Yammy can easily crush Soul Reapers with one of his huge hands, create extremely massive ceros, and boasts being stronger than Ulqiuorra, Nnoitra, and Grimmjow combined.

In contrast to the majority of her fellow Espada, Halibel prefers not to engage in combat, much less commit acts of unnecessary slaughter; she is content with silently observing the battle between Soul Reapers and Arrancars until it reaches its conclusion and refuses to fight unless she or her Fracciones are challenged or ordered by her superiors.

After saving the three Adjuchas named Emilou Apacci, Franceska Mila Rose, and Cyan Sung-Sun, who joined her campaign, Halibel becomes at odds with Baraggan for defying him and made an enemy out of a Hammerhead hollow who attacked her group once becoming an arrancar.

[24] Compared to the other Espadas, having empathy for the least fortunate hollows that remain as feral monsters, Nelliel has a sense of honor and respect for her opponents who she sees as warriors and only kills with good reason.

This ideology results with her being attacked by Nnoitra Gilga from behind as part of the Espada's revenge scheme with the help of Szayelaporro's device, managing to crack her mask and tossing her unconscious body out of Las Noches before enough of her spirit energy leaked out to shrink her into current form.

But as the resulting amnesia freed her of the sorrow that plagued her, Nel was able to live a carefree life with her two Fracciones bent on protecting her from the dangers of Hueco Mundo while making sure she does not remember.

By the time she is introduced in the series, Nel and her companions encounter Ichigo Kurosaki's group and help them as their guides in Hueco Mundo, though were originally afraid of Soul Reapers as they saw them to be the bad guys.

[27] As an Espada member who represents the aspect of death of Emptiness, Ulquiorra is emotionless with an inability to comprehend the meaning of "heart" and supports his firm belief that what his eye cannot see does not exist.

[34] When released, his zanpakutō, Murciélago (黒翼大魔, Murushierago, Spanish for "Bat," kanji translates as "Giant Black-winged Demon") creates two large black bat-like wings on his back.

[36] He becomes demonic and black-furred with clawed hands and feet, his espada number completely disappears from his skin, his sclera turn green, he grows a long thin prehensile tail, and gains markings similar to blood flowing freely from his hollow hole where his heart would be.

[37] In this new form, his reiatsu lances develop flame-like tips, these are dubbed as Lanza del Relámpago (雷霆の槍, Ransa deru Reranpāgo, Spanish for "Spear of Lightning"), and when thrown, explode upon impact; these detonations are immense enough to dwarf even the massive Las Noches, which is apparently bigger and much taller than a large city; this technique is the most destructive out of all the Espadas.

His zanpakutō is Brujería (呪眼僧伽, Buruheria, Spanish for "Witchcraft," kanji translates as "Sangha of Bewitching Eyes"), which replaces his legs with a hardened lotus-like structure that he can hide within as a defensive measure.

Szayelaporro eventually nullifies Uryū's abilities from studying Cirucci's corpse, playing with his opponents before deciding to personally kill them after his domain is destroyed in the fight despite Pesche and Dondochakka's attempted surprise attack.

In place of a head, Aaroniero has a pair of infantile skull-like creatures which float inside a glass capsule filled with red liquid, which is usually covered with a tall white mask.

Arrancar 105 Cirucci Sanderwicci (チルッチ・サンダーウィッチ, Chirutchi Sandāwitchi) has an appearance similar to a gothic lolita; her outfit consists of a frilly dress, large, round sleeves that cut off at her shoulder, short purple-colored hair, teardrop markings on each cheek, and knee-high boots.

His Zanpakutō is Tijereta (五鋏蟲, Tihereta, Spanish for "Earwig", Japanese for "Five-Pincered Insect") which looks like a standard katana with a guard shaped like to oval with a gap going down the middle and hollow corners.

Before Choe Neng Poww can finish off Ikkaku, Sajin Komamura takes over the fight while Tetsuzaemon places some poles on the ground to keep the real Karakura Town from materializing.

First summoned to the Fake Karakura Town, Ayon easily takes out Rangiku Matsumoto, Momo Hinamori, Tetsuzaemon Iba, and Shūhei Hisagi single handed, until Captain Yamamoto joins the fray to use his Shikai to destroy the beast.

They are listed in order of their number ranks: Iceringer Wernarl (アイスリンガー・ウェルナール, Aisuringā Werunāru, romanized as Aisslinger Wernarr in the Japanese media) is the 17th Arrancar in Sōsuke Aizen's army and one of the gatekeepers of Las Noches.

Loly, who hates Orihime out of both envy and later fearful prejudice, appears as an arrogant young woman with black hair tied in pigtails, a short schoolgirl-themed skirt, and the remains of her mask surround her left eye socket.

Loly's Zanpakutō is Escolopendra (百刺毒娼, Esukoropendora, Spanish for "Centipede," kanji translates as "Hundred Poisonous Stings") which takes the form of a small dagger with a curved guard.

Arrancar 61 Rudbornn Chelute (ルドボーン, Rudobōn) is the leader of the Exequias (葬討部隊, Ekusekiasu, Spanish for "Funeral Rites", kanji translates as "Funerary Attacking Force"), a group responsible for dealing with rebels and intruders in Las Noches.

Despite overwhelming her with his Calaveras, Rudbornn is subsequently defeated when the distraction by Yasutora Sado and Renji Abarai allowed Rukia to use her shikai to encase him in ice before being punched by an enraged Yammy.

[65] Modified by Aizen using the Hōgyoku as a weapon to render Yamamoto's Zanpakutō completely useless, the process removed all forms of Wonderweiss' rationality, his memory retention, speech, and intelligence.

He later appears during Aizen's assault on Karakura Town leading a massive hollow called Hooler, impaling Jushiro Ukitake with his bare hands, and then freeing Halibel from Tōshirō Hitsugaya's ice prison with a sonic scream.

He was created by an Arrancar medic named Roka Paramia as a clone of Szayelaporro Granz prior to him purging Ilfort Grantz's essence from his body, making Cien more violent in personality.

Anime News Network praised Kubo's "grasp of character and storytelling" in his creation of hollows who are not "the average monster of the week", but have "strong emotional ties" to their victims.
