Master Swordsmanship: Though he rarely uses his sword during combat, He is a highly skilled swordsman.

He possesses various abiliities, including : This means that he is the fourth strongest. Ulquiorra is the Cuarta Espada in Aizen's Arrancar force, which literally means 'Fourth Espada'. Ulquiorra realizes what 'The Heart' that Orihime mentions finally is. Ulquiorra realizes at the instant, he says, 'If you don't kill me now'.

The final blow in fact, was dealt by Ulquiorra who impacted Ichigo with a Lancero Verde. But as quick as a flash Ichigo's hollow side takes over and cuts Ulquiorra to ribbons as it may seem. But in fact, because he is weaker up to a certain point in the story, Ulquiorra refers to him as trash. Ichigo Kurosaki is seen as Ulquiorra's main rival. Other than Aizen, Ulquiorra is shown to only have a respectful relationship with Tosen and Aizen, he seems to get along with his partner Yammy well enough, though this seems to half be a relationship based on his power over Yammy than anything else. Grimmjow believes that Ulquiorra is afraid of fighting him, as he believes that the conflict would destroy them both. It was due to this argument that Grimmjow launched an attack on the real world that led to his own disgrace. In particular it gets Grimmjow the wrong way, and the two often argue. Ulquiorra considers all those weaker than him trash, and this attitude does not earn him much support. When confronted by a opponent he deems unworthy, he even refuses to draw his sword to fight them, preferring to use his hand to hand combat skills and invulnerability to beat them down, though this style is not limited to Ulquiorra: all the Arrancar tend to fight in this way, as they consider using their blades on an unworthy opponent disgraceful. It is perhaps due to this eye technique that he is deeply analytical of any situation or individual he comes across, and in combat he prefers to stand back and let Yammy do the combat merely remarking on the opponents abilities and advising Yammy of their abilities, his own potentials (and failings) etc. He professes that since he cannot see emotions with his enhanced vision, that they are a lie and cannot exist, as his eye is capable of seeing through anything. He has a particularly difficult time understanding human emotions, such as love. He deems anyone below him 'trash', pawns to be played, used and discarded: expendable assets under Aizen. In fact, he has shown himself capable of non-lethal violence towards Yammy in return, hitting him to get his attention. He has not shown any care or respect to any who are weaker than him, even watching his partner Yammy kill other Arrancar with no care. Ulquiorra has been shown to be very aloof and callous, looking down on all those whom he judges as beneath him. His Espada number is tattooed on his chest. His hollow hole was initially located at the base of his throat, but was later changed to his sternum.

This has lead to speculations that he is a Vasto Lorde, as the silhouette of the Vasto Lorde is similar to the silhouette of Ulquiorra. The remains of his hollow mask appear as a broken horned helmet on his head. Ulquiorra is almost always seen with a melancholic/emotionless expression on his face. He wears the typical Arrancar uniform, but his jacket has a longer coattails and a higher collar. He has green lines that descend from his eyes that make him look like he's crying.

He has shaggy black hair and green eyes with pupils similar to a cat. Ulquiorra is a thin but muscular Arrancar.
