Ulquiorra's Zanpakuto

Well, I'll try posting his non-Zanpakuto abilities and powers. They're so many that's why I just post about the Zanpakuto. Here is Ulquiorra-kun's Zanpakuto abilities.




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

 Release Command: "Enclose" (鎖せ, tozase). 

Murciélago unleashes a black (with green outline) burst of spiritual energy that falls around Ulquiorra as green rain. 

Appearance: Ulquiorra becomes bat-like in appearance. While in this form he gains large black bat wings on his back, his hair becomes longer and wilder, 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 black, 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 can use his wings in flying.

Special Abilities: 

Luz de la Luna : He is shown to have the ability to generate green energy javelins. He uses them as ranged weapons throwing them at an opponent and as a melee weapon.

Enhanced Speed : His speed is greatly enhanced, able to move great distances in an instant as if to displace himself, and able to push Ichigo to the point that even his Hollow mask-enhanced Bankai has difficulty keeping up.

Enhanced Hierro: His Hierro has also vastly increased in strength to the point where a Getsuga Tenshō with Ichigo's mask activated has no effect at all.

Enhanced Spiritual Power : Though already possessing immense spiritual power once released his black, green outlined spiritual energy permeates the area, it is intense enough to create a profound effect on others as well as to cause what appears as green rain to fall in the surrounding area when he releases.

Cero Oscuras : It is a black Cero with a green outline to it, which Ulquiorra states to be similar to Ichigo's black Getsuga Tenshō. This Cero presumably can only be used while he is in his release state. 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. Ulquiorra refers to it as "our Cero". It can also be used in the Segunda Etapa form.

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 "Sword's Release: Second Level") 

Upon his transformation, Ulquiorra boasts that he is the only Arrancar among the Espada who is able to reach a second Resurrección form, and that even Aizen has not seen him in this form. Ulquiorra refers to his second state as "True Despair", both before and after its release, because the immensely dense spiritual pressure it releases instills despair upon those around him. While he retains his black wings, his long white coat is gone, revealing a more defined musculature with his chest bare and Hollow hole (which has become larger) dripping black, blood-like liquid. His waist becomes covered in something similar to black fur, which also covers his arms and legs. His fingers grow claw-like extensions and his feet become like talons. The irises of his eyes turn yellow while the sclera becomes green. The tear-like marks under his eyes increase in size and turn black. Ulquiorra's mask is now completely gone, as he has taken on the fuller appearance of a bat. He now has two large bat- ears, and the #4 Espada tattoo is no longer visible on his chest.

Latigo : He grows a very long and thin but powerful tail which is capable of being used as a whip or to lift and strangle a victim.

Overwhelming Reiatsu : Ulquiorra's already-immense spiritual power significantly changes its Reiatsu's nature upon entering his second stage. Even being within the vicinity of his release instills despair on those who can sense it. 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..." (It should be noted that Ishida was describing its nature not its level of power).

Lanza del Relámpago : Ulquiorra creates a javelin-like weapon using his spiritual power. It is quite like his original energy javelins, with the only, if quite noticeable, difference being the energies flowing off of each end in a fashion similar to flames, making it look more arrow-shaped. He can use this weapon as a projectile or as a physical weapon. When thrown, it produces an incredibly-destructive explosion on impact, which dwarfs the fortress of Las Noches in height. Ulquiorra prefers to not use the attack at close range, most likely because the resulting blast would damage himself as well as Las Noches. While he can use these spears in rapid succession, he has difficulty controlling their trajectory. Ulquiorra is also able to use this attack as a blade, and he can use it to either disintegrate material upon impact, as seen when he struck away his own amputated arm that Hollow Ichigo had just thrown at him; or to cut, as seen when he used it to sever one of Hollow Ichigo's horns to prevent him from using a Cero on Uryū.
