Ulquiorra Cifer

is the cuarta (4th) Espada in Aizen's recently-acquired army of hollow-shinigami hybrids, and is one of the chief antagonists of the Arrancar, Hueco Mundo, and Fake Karakura arcs, being responsible for much of the conflict that transpires within all three story arcs, and is one of Ichigo's primary arrancar rivals, the other differentially being Grimmjow Jeagerjaques.

Appearance
Ulquiorra is a relatively short and slender, yet fairly muscular male arrancar with a melancholic appearance, short, messy black hair, silver skin, and green eyes with slit pupils. He has cyan lines that descend from his eyes, making it appear as if he is crying. His facial expression rarely changes, and he is near-constantly frowning. He also appears to be the youngest member of the Espada, next to Szayel, Grimmjow, Neliel, and Cirucci. He wears typical Arrancar clothes: a white jacket, black sash, and a white hakama. They are somewhat similar to what Ichigo's inner hollow wears. However, his jacket seems to have longer coat-tails than others. Like most other arrancar, he possesses remnants of his former life as a Hollow in his appearance. His Hollow hole has moved; it is at the base of his throat as opposed to his chest. The remainder of his hollow mask lies on top of his head, forming a broken helmet, much like that of the example silhouette of a Vasto Lorde. He is the fourth-ranked Espada, signified by the tattoo on the left side of his chest. It should also be noted that Ulquiorra's hollow hole seems to have moved since his first appearance, as it is now located somewhere near his sternum. This movement occurs in both the manga and anime.

Personality
Ulquiorra is a very cold, callous figure, hitting his comrade Yammy in the stomach with his arm on one occasion in an effort to get his attention. He's also rather dispassionate and rarely shows any sign of emotion, often appears depressed, and is rather aloof, brooding, and indifferent, willing to harm both his comrades and enemies should they ever disrupt his plans. He tends to call anyone he does not find interesting "trash", and therefore expendable. Despite this, he is not particularly violent, unlike most of his Espada comrades, and will only fight whenever provoked or ordered to by Aizen. As noted by Grimmjow Jeagerjaques, Ulquiorra has a habit of stabbing people in the same location as his hollow hole whenever he's particularly interested in a battle. Whether he is consciously aware of this habit or not is unknown. However, his speech to Orihime indicates that he is, as he speaks of never seeing the "human heart (emotions)" that living humans possess and understand, and reasons that if his eye cannot see them, then they are not real. These words, and much of Ulquorra's overall behavior, can safely lead one to assume that he is a firm believer in the concept of materialism. It would appear that as a result of his isolated life as a hollow, Ulquiorra does not understand feelings and emotions as well as empathetic characters like Orihime tend to. His overall behavior towards his allies and enemies, as well as his apparently self-inflicted habit of stabbing people in the chest, may symbolize that fact.

Ulquiorra is perceptive, cunning, and analytical; during his and Yammy's first visit to the human world, he makes several remarks on the humans who confront them. He theorizes that Orihime Inoue's healing power is a temporal-spatial ability, which Aizen describes as the rejection of fate and comments on how Ichigo Kurosaki's Bankai can easily get through Yammy's defenses. He also notes Ichigo's power fluctuation, which varies between very weak and stronger than his own.

It would appear that Ulquiorra and Grimmjow, the 6th Espada, are not on good terms. While Ulquiorra allows Yammy to kill anyone he deemed as "trash", which includes Ichigo, Ulquiorra allows him to live based on his belief that Ichigo's power is so turbulent that eventually he will destroy himself. Grimmjow's conflicting viewpoint is that Ichigo should be destroyed outright, as he can overcome his weakness and grow even stronger. Despite Grimmjow's argument, Aizen trusts Ulquiorra's judgment. This disagreement leads to Grimmjow's unauthorized assault on the real world. Though Ulquiorra is of a higher rank than Grimmjow, Grimmjow is confident that Ulquiorra is afraid to fight him, for fear of them destroying one another.

Ulquiorra seems to be demanding as well, such as when he came to Orihime's chamber and ordered her to eat a meal a servant Arrancar brought in, claiming it was her "duty" to stay alive for Aizen's benefit. When Orihime hesitated, he threatened to force the food down her throat, or strap her to a table and feed her via an IV. This also implies that, while he prefers not to dirty his hands, Ulquiorra is fully capable of committing truly abhorred and inhumane actions, even more so than Aizen and the other Espada.

Arrancar arc
Ulquiorra first appears alongside Yammy when they arrive in Karakura Town to gain information on Ichigo Kurosaki. Ulquiorra retreats with Yammy once he finishes examining Ichigo's abilities, also taking note of Orihime Inoue's fate-manipulation powers. A month later, Ulquiorra sends a second group of Arrancar (not counting Grimmjow's rogue actions) consisting of several Espada, meant to distract the Shinigami while he captures Orihime. By threatening her friends lives, he convinces her to come peacefully, allowing her to say goodbye to one person beforehand.

Hueco Mundo arc
Upon returning to Las Noches, Ulquiorra claims that he has trapped Orihime in a psychological prison from which her loyalty to Aizen is guaranteed, though this proves to be false when Orihime resolves to ruin Aizen's plans. Ulquiorra reappears to fight Ichigo, which ends in a sound victory for Ulquiorra. He leaves Ichigo alive but badly injured, suggesting to him that he should retreat if able. After discovering that Grimmjow has taken Orihime, Ulquiorra tracks them down and engages in a short battle with Grimmjow, ending with Grimmjow using a portable Negación field to temporarily trap Ulquiorra. He then escapes and is left in charge of Las Noches and is currently awaiting the arrival of Ichigo Kurosaki. While waiting, he questions Orihime if she feels any fear in knowing that she will die alone. She boldly answers no, and states she has confidence in her friends and Ichigo, and that she is not fearful because her heart is with them. Ulquiorra, unable to understand how she can harbor such feelings, presses her further. He asks her what a heart is, and reaches out to touch the area above her heart, asking where he can find it. But just as he is about to further interrogate her, Ichigo breaks in and is ready to battle. Ulquiorra then unsheathes his sword to eradicate Ichigo in order to protect Las Noches. They appear to be on even ground as of yet, with neither doing any major damage to the other.

Fake Karakura Town arc
As their battle continues Ulquiorra shoots his Cero at Ichigo, although he manages to withstand it. Ulquiorra then notes that Ichigo has gotten stronger, and asks him if it is because he has defeated Grimmjow, because he is trying to save Orihime, or because his friends are fighting down below them. Ulquiorra states that it doesn't matter either way because Orihime is already one of "us" and nothing can change that. Ichigo replies that isn't up for Ulquiorra to decide. After saying that, Ulquiorra finishes with saying that was Aizen's decision. As the two continued to fight, Ichigo gained the ability to to read Ulquiorra's movements, stating that either he was becoming more human in Ichigo's eyes or he himself (Ichigo) was becoming more Hollow. In response, Ulquiorra stepped up his tactics but he was stopped by Orihime's shield. He then questions her why she did not protect Ichigo when he started fighting him to begin with. Then he is able to get the hang of Ichigo's Bankai as they continue fighting. When Ichigo was about to attack Loly and Menoly who have grabbed Orihime while she stood back from the fight and threaten to pluck out her left eye if he advances on them Ulquiorra intercepts Ichigo and misdirects his Getsuga Tenshō. However, he tells Loly not to get the wrong idea about his actions and that he isn't helping her. He then continues blocking Ichigo's way to Orihime while monitoring the situation behind him and tells Ichigo that he will have to kill him in order to fight anyone else. Then he notices Yammy coming through the doors that Loly and Menoly entered from. During the lull in the fighting his entrance creates Yammy states that he's there to help him to which Ulquiorra replies he didn't ask for his help though he notices Yammy has recovered fully. Ulquiorra tells him his job elsewhere then suggests he should go back to sleep or fight the other Captains that are nearby but Yammy refuses. When questioned by Yammy about why the females are there Ulquiorra simply tells him to ask them, turning around to engage Ichigo once more and block his path to Orihime.

After Yammy defeats Menoly and Loly, he asks Ulquiorra if he is allowed to kill Orihime next, but Uryū Ishida arrives and uses a special landmine to critically injure him. After Yammy falls to the bottom of Las Noches, Ichigo finally dons his Hollow mask and he proves to be completely resistant to Ulquiorra's attacks, even managing to begin cracking his blade. Ulquiorra heads to the top of the dome of Las Noches and Ichigo follows him. As Ichigo notices their location, Ulquiorra explains to him that there are two things forbidden withen Las Noches: the first that the Espada's Gran Rey Cero should not be used, and that the top 4 Espada are forbidden to release their zanpakutō within Las Noches, as either has the potential power to destroy the city. He then subsequently proceeds to release his own zanpakutō with the command "Bind", followed by "Murciélago".

After going into his released state, Ulquiorra warns Ichigo to stay focused and alert before using sonido and attacking him with a spiked weapon. Ichigo defends the attack with a Getsuga Tenshō that he reflexively releases, but still has the upper-right portion of his mask ripped away in the attack. Ulquiorra notices the reflex and says that if Ichigo had not done so, then his head would be lying at his feet.

Powers & Abilities
Ulquiorrra is the Cuarta Espada in Aizen's army, meaning Ulquiorra's abilities are fourth amongst all of the arrancar and hollow under Aizen's command. His might is great enough that he can fight on even grounds with a full strength Ichigo while in bankai form and withstand most of the impact from a black Getsuga Tenshō.

Keen Intellect: In addition to his remarkable combat prowess, Ulquiorra is also gifted with great insight and understanding to situations at hand. His intelligence is such that even Aizen, a man arguably best-known for his intellect, has respect for as he sent Ulquiorra to investigate Ichigo's power and threat level. With his calm and collected nature, Ulquiorra has can be highly perceptive and analytical, allowing him to easily deduce the basic idea of his opponent's skills to figure out its strengths and weakness.

Cero: Ulquiorra has been shown using Cero from his fingers with very destructive power. His Cero is a green color instead of red, which is more common among Arrancar and Hollows.

Black cero:While ichigo is fighting Ulquiorra he tells ichigo that his getsuga looks like a cero from a released espada and than fires from his finger a black cero.

Bala: The technique hardens the user's spiritual pressure and fires it like a bullet from their fist.

Hierro (鋼皮（イエロ）, Hiero; Spanish for "iron"): refers to the hardened skin of the arrancar, which is a result of their compressed spiritual power. He can deflect attacks of similar power barehanded. He is able to fight Ichigo in his Hollow form without unsheathing his sword, rendering Ichigo defenseless with two attacks and not sustaining injuries of any kind. He could also take a direct hit from Ichigo's Tensa Zangetsu with only a minor cut on his chest.

Enhanced Strength: Ulquiorra has proven to be deceptively strong for his built. He has shown able to physically discipline Yammy, an Espada arrancar known primarily for his strength, with no visible effort in an elbow strike. He has also shown the ability to kick Ichigo Kurosaki a tremendous distance with one kick.

Garganta (黒腔（ガルガンタ）, Garuganta; Spanish for "throat"): is how Arrancar move to and from Hueco Mundo. Ulquiorrra has 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. In the games, Ulquiorra uses this technique to generate make-shift vortices to draw opponents in, as well as teleport from place to place.

Sonído Expert: One of Ulquiorra's more noticeable traits is his tremendously skillful speed. He has demonstrated the ability to catch up with Ichigo Kurosaki after kicking him from a tower in a few moments. He has also shown the ability to skillfully keep up with Ichigo's bankai speed. In addition, his superior experience allows him to push Ichigo's reflexes to the limit.

Instant Replay: Ulquiorra has the unusual ability to replay events he has seen to others by removing and crushing an eye, which then turns into dust and flows around those Ulquiorra intends to use it on. The dust shows images of what Ulquiorra has seen during his missions.

Regeneration: Ulquiorra appears to have regenerative powers as after he removed and crush one of his eyes, he is seen with two eyes again in his next appearance, and Yammy comments on it to that effect.

Expert Hand-to-Hand Combatant: Though he hasn't shown the extent of his abilities in this field as of yet, Ulquiorra has shown to rely mostly on hand-to-hand combat, rarely drawing his sword at all. Ichigo speculates that he only draws his sword against opponents he considers "worthy". Ulquiorra also seems to prefer applying an 'off-the-ground' method of combat, often being seen attacking opponents from aerial standpoints, such as when he attempted to use his Cero on an offending Grimmjow Jeagerjaques by attacking him from the air above his head, or when he jumped upwards with a Sonido, in an attempt to catch Ichigo Kurosaki off guard during their most recent confrontation.

Vast Spiritual Power: His spiritual power is very high, comparing his own spiritual power to the likes of Ichigo. As on of the top 4 Espada, he is forbidden to release his zanpakutō within Las Noches. That is because they are too powerful and such a release would cause great damage. During his first meeting with Ichigo he comments that the shinigami's energy fluctuates from being "trash", to stronger than his own.

Master Swordsmanship Specialist: He appears to be very efficient in swordsmanship, being able to fight on-par with Ichigo Kurosaki and even slice through his Getsuga Tenshō. Ulquiorra prefers to wield his sword with his right hand, leaving the other hand free though it usually remains in his pocket. He is quite adept at blocking while his offense is capable of great precision. He was able to fend off Ichigo using his hollow mask-enhanced bankai long enough to reach the top of Las Noches, although his zanpakutō was nearly broken.

Zanpakutō
. The handle is green and the guard has two curved extensions from its shorter sides, giving it an eye-like appearance.


 * Resurrección: Its release command is . Murciélago unleashes with a burst of spiritual energy that falls around Ulquiorra as black rain. In his released state Ulquiorra becomes bat-like. He gains giant wings on his back, his hair becomes longer and wilder on the left side of his head, his hollow helmet centers atop his head, with two large horns extending outward to the sides towards the front. The lines on his face become broader and more triangular. His arrancar attire becomes more form fitting and closed at the top becoming more like a robe towards the bottom. In this form he uses a spike-like weapon instead of a sword that can easily destroy a small part of Las Noches, along with part of Ichigo's mask.


 * Resurrección Special Ability: He is also shown to have the ability to create elongated spikes. It would also seem that his speed is greatly enhanced to the point that Ichigo's hollow mask-enhanced Bankai has difficulty keeping up.He also have the ability to fire a black cero "Cero Oscurus" and tells ichigo that his getsuga looks like a cero from a released espada.

Appearances in other media
Ulquiorra is the first Arrancar to be featured in a Bleach video game, appearing in the Bleach: Heat the Soul 3 and Bleach: Heat the Soul 4 installments of the 'Bleach: Heat the Soul' series for the PlayStation Portable. He also appears in the Wii fighting game Bleach: Shattered Blade. He has a cameo and artwork in "Bleach: Dark Souls". He is also playable in the recent Bleach: Versus Crusade which he remains unchanged from the prequel.

Ulquiorra has his own character album as part of the Bleach Beat Collection 3rd Session. The two vocal tracks are entitled CRUSH the "WORLD" DowN and Our World.

Relationships

 * Sōsuke Aizen: He is quite loyal and obedient to Aizen. He fulfills all of Aizen's orders without question. However, it may be noted that he has occasionally been seen disobeying Aizen's orders in favor of his own, personal curiosities, such as when he purposely seeks Orihime Inoue out in order to question her about human emotions.


 * Ichigo Kurosaki: Initially, he referred to Ichigo as "trash" and not worthy of being killed, mostly because he believed that his unstable spiritual pressure would eventually destroy him in the long run, anyway. The next time they face in Hueco Mundo, Ulquiorra was able to provoke and in turn defeat him at full power without even unsheathing his blade; He also stabbed his hand through Ichigos chest leaving a hole resembling his own hollow hole. Grimmjow stated he only does such to prey he finds particularly interesting. In their most recent encounter, he acknowledged Ichigo as an opponent worthy of killing, at the very least that is. Later when Yammy interrupts their fight Ulquiorra repeatedly reminds Ichigo that if he wants to fight anyone else, he'll have to kill him first. Being the analyst he is, Ulquiorra is presumably attempting to draw out all of Ichigo's power.


 * Grimmjow Jeagerjaques: It would seem that he is not on good terms with Grimmjow, because he prevents Grimmjow from carrying out his ideals. Grimmjow believes that he is stronger than him and is eager to prove this to him. He and Grimmjow have conflicting personalities and this may be the main reason of their bad relationship.


 * Orihime Inoue: He was placed in charge of abducting Orihime, and subsequently, taking care of her well-being until she was needed by Aizen for her powers. His relationship with her appears to be limited to the task of bringing her food and occasionally informing her of her friends' struggles throughout Las Noches. He refers to Orihime as "woman" ((女) onna), both in thought and conversation. It can be noted that Ulquiorra seems rather intrigued by the concept of the 'human heart', questioning her about how she is so easily able to wear her emotions on her sleeves. During their most recent fight, Ichigo mentions Ulquiorra may have 'become more human'. This could signify Orihime's empathic personality affecting Ulquiorra's own emotional capacity; this could also however just be a false inference on Ichigo's part as he was only recently strong enough to truly face Ulquiorra in combat.

Trivia

 * He was recently voted the 10th most popular character in Bleach after receiving 3751 votes.
 * His first name comes from Patricia Urquiola, an architect, and his last from Father Hubert Schiffer, a survivor from the atomic bombing of Hiroshima, which is Tite Kubo's home town.
 * His name is possibly a reference to "El Que Llora" in Spanish, meaning "he who cries."
 * "Schiffer" means "boatman/sailor" in German.
 * Some fans speculate that Loly and Menoly are Ulquiorra's Fracción, since he is the only Espada seen giving them orders (and Grimmjow notes that they attacked Orihime when he wasn't around). However, in recent manga chapters, this doesn't seem to be the case, since Ulquiorra claims he isn't defending them from Ichigo, and he shows no concern when Yammy attacks both of them, likely due to his generally cold demeanor. Additionally, while Loly was trying to fight Yammy, she shouted that she would kill both Yammy and Ulquiorra, which leads one to assume that any supposed 'master/subordinate' bond would be nonexistent.
 * It is possible that Ulquiorra has been an Espada during Nel Tu's time as the third Espada, due to the fact that she seemed to remember his name.
 * In his released state, his helmet-like mask fragment becomes reminiscent of the silhouette of a Vasto Lorde's head.
 * It is heavily impilied that the the top four espada are Vasto Lordes because of the rule implied by Sōsuke Aizen for the top four Espada are forbidden to release thier Zanpakutō within the Las Noches.
