Ulquiorra

Biodata

Power Progression

• Next threshold: Five stars are required for Second Stage Resurrección. The stated upgrade costs are 30,000 Negative Points from three to four stars and another 50,000 from four to five; no five-star upgrade is documented in the supplied chapters 23.

Background

Ulquiorra originates from Bleach, where he is the fourth-ranked Espada of Las Noches and is identified as the only Arrancar capable of Second Stage Resurrección. His summoned incarnation does not immediately have access to that full power because the Forbidden Magic Book restricts his unlocked strength 22 23.

Ye Yang unlocks him as his second character and chooses to summon him rather than merge with his power. Already possessing Madara Uchiha’s abilities, Ye Yang needs an independent ally to share his workload. Ulquiorra emerges from a black curtain of light and immediately pledges himself to Ye Yang 22.

Ye Yang subsequently appoints him Fourth Forbidden Blade and personal guard. Although Ulquiorra kneels to accept the appointment, Ye Yang helps him up and tells him that kneeling is no longer necessary 23.

Appearance

• Base form: Short, choppy black hair, deathly pale skin, green eyes, and two dark green tear-like markings running down his face. He wears a white Arrancar uniform and a horned helmet covering the left side of his head 22.
• Forbidden mark: A black character meaning “forbidden” appears on the uncovered side of his head. It identifies him as a summoned character and serves as the medium through which Ye Yang can possess his body 22.
• Black-Winged Demon form: Enormous black wings, a full-length white robe, two horns, elongated claws, and deeper-looking tear markings. His expression remains emotionless despite his more oppressive presence 27.

Personality

Ulquiorra is reserved, formal, and sparing with words. He usually stands silently beside Ye Yang, addresses him as “Lord Ye Yang,” and responds to commands without argument. His repeated kneeling reflects his deferential conduct toward his summoner 22 23.

His unfamiliarity with the new world does not prevent him from asking questions. When his Cero fails to injure Kizaru, he looks to Ye Yang for an explanation. Later, he questions why Ye Yang leaves dangerous enemies alive and begins to understand the value of preserving them as sources of Negative Points 25 38.

His taunting behavior during the later battle with Kizaru occurs while Ye Yang is controlling his body; those remarks should not be treated as straightforward evidence of Ulquiorra’s independent personality 28 33.

Abilities & Skills

High-Speed Regeneration

Ulquiorra retained and strengthened a regenerative ability that other Arrancar did not retain 22.

• Rapidly restores damaged body parts, including severed arms and legs 22.
• Cannot regenerate the brain or internal organs 22.
• Ye Yang extracts this skill after summoning him and demonstrates it by healing a cut wrist almost instantly, without a scar 22 23.

Cero and Cero Oscuras

Ulquiorra concentrates spiritual energy at his fingertip and fires destructive dark green blasts 24 26.

• Cero: Creates a harbor crater over one hundred meters wide and deep, counters Akainu’s Great Eruption, and kills an attacking Sea King 24 26 38.
• Cero Oscuras: Uses a different concentration of spiritual power to swallow Kizaru’s Yasakani no Magatama barrage and blast away his upper body 26.
• Logia limitation: His ordinary energy attacks initially fail to inflict lasting injury on Kizaru, who disperses into light and reforms. Ye Yang explains that Armament Haki is needed to strike him effectively 25.
• While Ye Yang controls his body, Cero Oscuras is also used in the finishing assault against Kizaru 31 33.

Sonído and Close-Quarters Combat

Ulquiorra combines rapid movement with swordplay and physical attacks 24 25 26.

• Uses Sonído to intercept Akainu’s attack before it reaches Ye Yang 26.
• Evades a point-blank laser and appears behind Kizaru before the Admiral can track him with Observation Haki 25.
• Blocks Kizaru’s Light-Speed Kick with his Zanpakuto and clashes with Ama no Murakumo using a spiritually formed Moonlight Sword 24 25.
• His possessed body later moves too quickly for Kizaru’s Observation Haki to follow, even when the Admiral is watching closely 28 31.

Resurrección: Black-Winged Demon

His first-stage release is activated with the command “Enclose, Black-Winged Demon” 26.

• The release produces heatless dark green flames and a brief drizzle formed from spiritual pressure 27.
• Its transformation and increased power cause both Admirals to reconsider their chances of capturing him 27.
• Second Stage Resurrección is part of his original capabilities, but remains inaccessible below five stars 22 23.

Spiritual Pressure and Barriers

Ulquiorra can release oppressive spiritual pressure and shape spiritual power defensively 24 39.

• His released pressure is nearly tangible; Kizaru mistakes it for Conqueror’s Haki. This is not confirmation that Ulquiorra possesses Conqueror’s Haki 24 25.
• Creates a protective spiritual-power sphere for the descent toward Fish-Man Island 39.

Possession-Assisted Learning

The Forbidden Magic Book allows Ye Yang to possess Ulquiorra through his forbidden mark 22.

• Ye Yang supplies his own Armament Haki while controlling Ulquiorra, allowing the body to injure Kizaru 28 29.
• Ulquiorra’s consciousness remains sealed inside his mind but can still feel what his body experiences 33.
• Afterward, he remembers the sensation of Haki and believes he can learn it within a few attempts 33.
• Independent mastery is not yet confirmed: His immediate attempt after possession ends is unsuccessful 33.

Equipment / Weapons / Items

• Zanpakuto — Carried at his waist; used to block Kizaru’s opening attack and initiate Black-Winged Demon 24 26.
• Moonlight Sword — A weapon condensed from spiritual particles, capable of clashing with Kizaru’s light sword and cutting apart incoming lasers. Ye Yang coats it in Armament Haki while possessing Ulquiorra 24 25 27 29.
• Lanza del Relámpago — Listed among the skills Ye Yang could extract at summoning; no use is documented in the supplied battles 22.

Story Role / Major Arcs

Battle at the Sabaody Harbor

Ulquiorra’s first duty as Ye Yang’s guard is to intercept Kizaru’s Light-Speed Kick. He then engages the Admiral directly, demonstrating destructive power that Kizaru judges to be Admiral-level, though his lack of Armament Haki initially prevents him from overcoming Kizaru’s elemental body 24 25.

After Akainu arrives, Ulquiorra protects Ye Yang from a magma attack, counters Kizaru’s aerial barrage, and releases Black-Winged Demon. The Admirals attempt to separate guard and master: Kizaru draws Ulquiorra upward while Akainu targets Ye Yang 26 27.

Ye Yang secretly possesses Ulquiorra and uses Armament Haki to turn the aerial encounter against Kizaru. Through Ulquiorra’s body, he falsely claims that Kizaru had deliberately been kept alive as bait for Akainu and reveals that Ye Yang is the Dark Forbidden Legion’s king, not merely an accomplice 28.

The possessed Ulquiorra prevents Kizaru from pursuing the departing Marine warships and ultimately defeats him. Ye Yang orders both Admirals spared, then uses their captivity to negotiate a ransom of six Devil Fruits and 1.5 billion Beli 31 33 35.

Upgrade and Undersea Departure

After the battle, Ulquiorra reports that possession left him without discomfort and gave him a bodily memory of Armament Haki. Ye Yang then upgrades him to four stars, substantially increasing his strength 33 35.

Before leaving Sabaody, Ulquiorra questions Ye Yang’s decision to spare the Marine leadership. Ye Yang explains that living enemies can continue generating Negative Points. Ulquiorra begins to grasp the strategy after killing a Sea King and watching its blood attract others 38.

He accompanies Ye Yang toward Fish-Man Island, protecting himself from the deep-sea currents with a sphere of spiritual power 39.

Relationships

• Ye Yang — Summoner, commander, and the person he guards. Ye Yang grants him his Legion rank, upgrades his power, and temporarily possesses him during the battle with Kizaru 22 23 28 35.
• Kizaru / Borsalino — Principal opponent at Sabaody. Kizaru initially survives through Logia intangibility, but is defeated after Ye Yang supplies Armament Haki through possession 25 28 33.
• Akainu / Sakazuki — Enemy Admiral whose attack on Ye Yang Ulquiorra intercepts. Ulquiorra continues fighting Kizaru while Ye Yang handles Akainu 26 29.
