When he releases the sword, he gains giant bat wings.
Animal Motifs: "Murcielago", the name of his zanpakuto, means "bat" in Spanish. All he could do was see the world, which is why he only trusts what he can see as an Espada. And I Must Scream: As a Hollow, Ulquiorra was unable to feel, hear, smell, or eat anything. All There in the Manual: His backstory is not addressed in the manga or anime, but is instead revealed in the Unmasked datebook which furthermore reveals what exactly his unique Segunda Etapa form is. They tried to devour him for his different appearance, and Ulquiorra was forced to kill them in self-defense. All the Other Reindeer: In his backstory in Unmasked, Ulquiorra had a white body except for his wings and no mouth, while his brethren were jet black and had mouths. She says no and he finally starts to understand what being human is. As he dies, he asks Orihime if she's afraid of him. Despite not showing any sign of repentance, Ulquiorra's final scene is played for sympathy on his part. Alas, Poor Villain: Ulquiorra's character arc is about trying to understand the meaning of human emotions. He received a short comic made by Tite Kubo about his back story in the third data book, Unmasked, which shows his origins.
He has a hidden second transformation named Segunda Etapa that transforms him into a demon with vastly enhanced destructive and regenerative abilities. His Zanpakuto, Murcielago, transforms him into a bat-like demon that gives him incomprehensible speed and allows him to create energy javelins. His number tattoo is on the left side of his chest and his Hollow hole is in his sternum - though in his debut it was in the base of his throat. He defines the death aspect of 'Emptiness'. He considers Ichigo, and all others either weaker than him or human, little more than "trash". However, all traits put him in direct conflict with Grimmjow, to the point where though he acted as Ichigo's main rival, Ulquiorra has far more enmity for the Sixth Espada. The Fourth Espada, Ulquiorra is cold, rational, reserved, and absolutely loyal to Aizen, which more or less netted him the position of The Dragon despite not being his most powerful subordinate.
