Skills:

-Master Swordmanship Specialist:He appears to be very efficient in swordsmanship, being able to fight on-par with Ichigo 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, though his Zanpakutō was nearly broken.

-Master 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 by attacking him from the air above his head, or when he jumped upwards with a Sonído in an attempt to catch Ichigo off guard during their most recent confrontation.

-Sonido Master-One of Ulquiorra's more noticeable traits is his tremendously skillful speed. He has demonstrated the ability to catch up with Ichigo after kicking him from a tower in a few moments.[2] 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.

-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.

-Bala: The technique hardens the user's spiritual pressure and fires it like a bullet from their fist. Ulquiorra has a red Bala, as seen in the kidnapping of Orihime.

-Enhanced 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 not openly stated, it has been seen repeatedly that Ulquiorra's skin is highly durable even by Arrancar standards. 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. The best example of his hierro's might was shown from his ability to take a direct slash from Ichigo's Tensa Zangetsu with only a minor cut on his chest, while his fellow Espada Yammy lost an arm from the said opponent. Also, in his released form, Ulquiorra's hierro appears to be even stronger, as Ichigo's strongest attacks seem to have no effect on him.

Enhanced Strength: Ulquiorra has proven to be deceptively mighty for his build. He has shown the ability to physically discipline Yammy, an Espada known primarily for his strength, with no visible effort. He has also shown the ability to kick Ichigo a tremendous distance with one kick.[3]

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

-Garganta Broadcast: Garganta Broadcast: Ulquiorra has been shown able to create a visual broadcast , similar to a television screen, using individual Garganta portals. He does this in order to show the current predicament of Orihime's friends (Ichigo, Hitsugaya and Matsumoto) fighting their respective battles, stating he could kill them if she says anything other than "yes".[4] It is unknown if he could create as many as desired, or if three broadcasts are his limit.

Enhanced Vision: Accoring to Ulquiorra, his eyes have the power to see through any illusion or deception, to basically see and understand anything in its sight. He even goes as far as saying he can only not see what doesn't exist.

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.

High-Speed Regeneration: Perhaps Ulquiorra's greatest strength is his regenerative power. It is first witnessed after he removed and crushed one of his eyes, then he is seen with two eyes again in his next appearance, and Yammy comments on it to that effect. This is displayed once more in his battle against Ichigo's evolved Hollow form where he regenerates the arm that was torn off. Ulquiorra states that it is his greatest power, one which most Arrancar give up in return for greater strength. He explains that he can quickly regenerate any part of his body except for his brain and internal organs. However, this power also requires that he had sufficient spiritual energy.

Zanpakuto: Murciélago (黒翼大魔 (ムルシエラゴ), Murushierago; Spanish for "Bat", Japanese for "Black-Winged Great Demon"). Ulquiorra's Zanpakutō takes the form of a standard sized katana with a green handle and sheath. The guard has two curved extensions from its long sides, with a line going through both sides to give it an eye-like appearance.

Resurrección: - Its release command is "Bind" (鎖せ, tozase).[5] Murciélago unleashes with a burst of spiritual energy that falls around Ulquiorra as black rain. In his released state, Ulquiorra becomes bat-like in appearance. He gains giant wings on his back, his hair becomes longer and wilder on the left side of his head, and the remains of his Hollow mask 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 and his fingernails lengthen. 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 an energy spear instead of a sword.

Cero Oscuras (黒虚閃, (セロ・オスキュラス), sero osukyurasu; Spanish for "Dark Zero", Japanese for "black hollow flash"): It is a black Cero, which Ulquiorra states to be similar to Ichigo's black Getsuga Tenshō. Like many other Espada related techniques, this technique can only be used by Espadas in their released states. Ulquiorra's Cero Oscuras is powerful enough to blast Ichigo's mask away and destroy a large part of the city-sized Las Noches' dome. Since there is no rule that forbids an Espada to use Cero Oscuras in Las Noches, the Gran Rey Cero may be stronger than it, since it has a restriction. Yet while Ichigo was in his Hollowification state he countered Grimmjow's Gran Rey Cero, the technique may differ in power between the Espada. It is also possible that it is only usable in the Espada's released state, meaning it is only forbidden to be used by Espada of at least Cuarta (4, 3, 2, and 1). This however, would not include the Espada lower than Cuatra from simultaneously releasing their Zanpakutō and performing Cero Oscuras. Ulquiorra also refers to it as "my Cero",[6] so it may be exclusive to him. It is also possible that the Cero Oscuras is just a vastly powerful version of the Cero. Since the color of the Cero changes depending on who uses it, the "Oscuras" in its name may simply refer to the fact that his version is black.

Resurrección: Segunda Etapa (刀剣解放第二階層 (レスレクシオン・セグンダ・エターパ), resurekushion segunda etāpa; Spanish for "Resurrection Second Stage", Japanese for "swords release: second level") Ulquiorra boasts that among the Espada, only he possesses a second release form which even Aizen hasn't seen. However, this may just be an assumption, for the three higher-level Espada might be capable of similar transformations. Ulquiorra refers to his second state as "True Despair", both before and after its release, likely because its immense power instills despair upon the opponent. Segunda Etapa can be presumed as the Arrancar equivalent of a Shinigami's Bankai. While he retains his black wings, his long white coat is gone, revealing a more defined musculature with his chest appearing as blood-like liquid is dripping from his Hollow hole, which becomes larger. His waist is covered in something similar to black fur, his arms turn completely black, from the mid-biceps to the finger tips, and his fingers grow claw-like extensions; his feet become like talons, his eyes turn yellow while his sclera turns green and the thin "crying" marks under his eyes are displaced towards the outside of his cheeks by similar triangular lines that taper off towards his chin. Ulquiorra's mask remains turn into horns, and the #4 Espada tattoo is no longer visible on his chest. He grows a very long and thin but powerful tail which is capable of being used as a weapon or to lift and strangle a victim.

Overwhelming Spiritual Power: Ulquiorra is known to have vast spiritual power, and it increases quite a lot after releasing Murciélago, but it's not until his Second Stage that his power becomes unbelievably great. Uryū Ishida, a Quincy who is an expert at sensing reiatsu, noted that the density of Ulquiorra's spiritual power was so vast that it could hardly be identified as reiatsu. "It's like no spiritual energy I've ever felt before...It's not just bigger or stronger. It's too dense and heavy to even be called spiritual energy. It feels like there's an ocean above the sky..." [7] His second form's reiatsu was able to easily overpower Ichigo Kurosaki's when the latter was using both his hollow mask and bankai.

Instantaneous Cero Oscuras: In his second state, Ulquiorra can use a fully powered Cero Oscuras without having to charge it. In addition, the blast travels very swiftly, with speed comparable to that of a Bala. The Cero retained its enormous power from Ulquiorra's previous form, being so powerful that it was able to blow a large hole through Ichigo's chest.

Lanza del Relámpago (雷霆の槍 (ランサ・デル・レランパーゴ), ransa deru reranpāgo; Spanish for "Lance of the Lightning", Japanese for "lance of thunder and lightning"): Ulquiorra creates a javelin-like weapon using his spiritual power, which can be used offensively or turned into a projectile. Upon impact, it produces an incredibly destructive explosion so big it dwarfs the fortress of Las Noches in height. Ulquiorra prefers to not use the attack at a close range, likely because the resulting blast could possibly damage himself as well as Las Noches. Whilst he can use these spears in quick succession, he has difficulty controlling them. He also seems to be able to use this attack as a physical weapon like a blade, as seen when he used it to sever one of Hollow Ichigo's horns to prevent him from using a cero on Ishida.
