Hollow Ichigo

Hollow Ichigo (虚 ホロウ 一護), sometimes called Zangetsu (斬月, Slaying Moon) is the manifested spirit of Ichigo Kurosaki's Zanpakuto spirit as well as his inner Hollow. He has been variously called The Hollow within Ichigo's conscience (一護の内面 (ないめん) の虚 ホロウ) or White Ichigo (白一護). Inherited from his mother, Masaki Kurosaki, Hollow Ichigo represents the dark side of Ichigo's soul. He has stated himself to represent Ichigo's purest instincts. Therefore he represents Ichigo's dark personality.

Background
He was born when Ichigo Kurosaki went under training to awaken his Shinigami powers, and quincy powers.

Personality
Hollow Ichigo's most distinguishing features are his maniacal laughter and psychotic grins. He is brutal, arrogant, disrespectful, and sadistic. He has no name, and his only reason for existence is to take over Ichigo's power and body and use it to kill everything and anything he sees, as opposed to Ichigo's desire to protect. Though he taunts Ichigo as being a weak and unsuitable counterpart of himself, he relishes the idea of taking Ichigo's powers for himself. Unlike Ichigo, he battles like a berserker, ignoring injuries and overpowering his enemies with brute strength and force. He protects Ichigo's body when he is about to die because if Ichigo dies, he will die as well. He seems to respect the manifestation of Ichigo's Quincy powers to a certain extent.

Hollow Ichigo has declared Ichigo is the "king" of the inner world, and he is the "horse". He wishes to "take the crown" from Ichigo so he can have control over his body and become the dominant personality. After his loss, he states he is willing to allow Ichigo to keep the crown for now, but once Ichigo "screws up again", he will make his move once more.

Appearance
Hollow Ichigo appears to be identical to Ichigo, except inverted in color. He is a fairly tall and lean-built being with white skin and hair. His eyes consist of black pupils, white irises, and black sclera. He has black nails. While Ichigo wears a standard black Shinigami shihakusho, his Zapakuto spirit wears a white shihakusho with a black cloth belt. When he is later pulled out of Ichigo by the manifestation of Ichigo's Quincy powers, he wears the Bankai version of Ichigo's shihakushō, except white. In addition, he dons the horned mask Ichigo possessed in his fully Hollowfied form.

When he is merged with Ichigo's Quincy powers, much of the manifestation's personality seems to be in effect, making the merged spirit much calmer, though he is prone to occasional outbursts similar to Zangetsu. He states he wishes to protect Ichigo, contrary to his frequent earlier statements of wanting Ichigo's body and power for himself.

Master Swordsman
Hollow Ichigo's skill in swordsmanship has developed alongside Ichigo Kurosaki's. His ingenuity in it is much greater than Ichigo's, for he can use his Zanpakuto in more versatile and effective maneuvers, such as using his Shikai as a flail, with which he has demonstrated tremendous aim and control of where and how it strikes. While Ichigo fights in a deductive and logical manner, Hollow Ichigo fights in a style more akin to a berserker, relying on instinct with little to no regard towards his own well-being.

Deadly Darts
(デッドリー・ダーツ, deddorī dātsu): Hollow Ichigo uses the cloth on his blade to swing his Zanpakuto and toss it at opponents for mid-range combat. The blade moves very fast when thrown, and its impact can damage a building. If the person dodges the attack, Hollow Ichigo can use the cloth to manage the sword's direction and try to hit the target once more. By gripping the cloth, he withdraws the blade and swings it to attack again.

Expert Hand-to-Hand Combatant: Drawing from Ichigo's experience, Hollow Ichigo is a highly capable unarmed fighter. While mostly relying on his Zanpakuto in battle, he will occasionally use unarmed attacks to surprise and incapacitate his opponents.

Highly Perceptive Combatant
Despite his arrogant and insane demeanor, Hollow Ichigo is a very insightful and crafty fighter. While regularly mocking Ichigo, his mocking also has deep rational knowledge behind it which ultimately helps Ichigo come to better understand himself and his powers.

Hollow Ichigo's intellect has also been useful in battle. He quickly realizes mistakes in Ichigo's battle tactics and corrects them, and almost instantly adapts to his opponent's battle tactics to perfectly counter them.

Vast Spiritual Power
Hollow Ichigo can emit a large amount of uncontrollable red-colored Reiatsu, which can pulverize the area around him. When Hollow Ichigo began taking over Ichigo's body, Ulquiorra Cifer, the 4th Espada, stated Ichigo's Reiatsu fluctuated from weak to higher than his own. His Reiatsu is great enough to visibly intimidate the Hollowfied Hiyori Sarugaki and the rest of the Visored.

Enhanced Strength
Hollow Ichigo is much more powerful than Ichigo, allowing him to overpower Ichigo very easily. His physical strength is much greater than Ichigo's. He thrust his Zanpakuto into Go Koga's doll Dalk, while she was in her spider form, and effortlessly pushed her back with it. After taking over Ichigo's body, he grabbed Hiyori's throat, breaking most of her mask, and would have choked her to death if the other Visored had not interfered. He can thrust his Zanpakuto into or throw an opponent through a wall.

Enhanced Speed
In addition to having greater raw strength, Hollow Ichigo is noticeably craftier and more agile in his movements than Ichigo. He can catch his blade in midair and perform a salto before landing. He can easily dodge a tentacle attack from Dalk or a surprise attack, and strike back as soon as possible. He grabbed Hiyori's throat before she could defend herself. His attack patterns are generally harder to read and keep up with, allowing him to strike down his opponent easier.

Enhanced Durability
When the manifestation of Ichigo's Quincy powers fired a second Getsuga Tensho at Ichigo, Hollow Ichigo took control and emerged from the destroyed wall with no visible damage.

Advanced Growth Rate
Like Ichigo, Hollow Ichigo has an astounding growth rate. He gains any power Ichigo does, evidenced by his use of Bankai. He could use the black Getsuga Tensho before Ichigo, despite both learning Bankai around the same time. His own Getsuga Tensho is incomparably stronger than Ichigo's.

Mask Shielding
Because Ichigo's body is necessary for his very existence, Hollow Ichigo protects it with his mask. During Ichigo's more difficult battles, he manifested the mask to block attacks on Ichigo's body from within his shihakushō, serving as a shield to stop or lessen attacks on him, sometimes saving his life. The mask blocked several hits from Renji Abarai's Zanpakuto, which could have been fatal. Although the mask was thrown away afterwards, it reappeared while Ichigo was fighting Kenpachi Zaraki, preventing his torso from being cut in two.

Possession
Hollow Ichigo can take over Ichigo's body and powers when Ichigo falls unconscious in a fight. When this occurs, Ichigo's sclera blacken, and his irises glow golden-yellow in combination with a Hollow mask forming on the left side of his face. If the mask is broken or torn off, Ichigo will regain control over his body. During his time as the dominant spirit inside Ichigo's mind, Hollow Ichigo could call out to Ichigo, eventually interrupting his thought process, and try to take over in the middle of a fight. If Ichigo manages to drive him back, only his eyes will change for a moment, and the mask will not begin to form. Hollow Ichigo's influence is great enough to force Ichigo's eye to blacken while Ichigo is in his Human body.

Hollow Form
When Hollow Ichigo takes full possession of Ichigo's body, the body undergoes a full transformation into a Hollow creature. His mask resembles a Human skull, complete with a jaw joint and rounded forehead, and has dark red stripes on the left side. This full Hollow is a white humanoid lizard with three-toed feet and a tail, with black marks all over its noticeably more muscular body. It possesses long orange hair and reptilian eyes seen through the eyeholes on its full mask. Unlike normal Hollows, this form used an actual weapon, using Ichigo's Zanpakuto. When Ichigo's powers are somewhat restored by Kageroza Inaba's Kaizo Konpaku equipment, the mask takes the design of his second Hollow form. Additionally, the fur around the wrists is red instead of grey.

High-Speed Regeneration
Like some Hollows, Hollow Ichigo possesses the ability to instantly regenerate any wound and even a missing limb.

Enhanced Getsuga Tensho
Hollow Ichigo's Getsuga Tensho completely surrounds his blade. The extent of its power is currently unknown, for it has never been utilized in this form.

Enhanced Spiritual Power
Even when only partially transformed, Hollow Ichigo's Reiatsu greatly increases. Upon awakening, the Hollow form broke free from a full-powered '''Bakudo #75. Gochutekkan'''.

Cero
Hollow Ichigo can fire a potent Cero from either his fingertips or his entire hand. This Cero is crimson and tri-focused. The blast is strong enough to overpower a Getsuga Tensho from the manifestation of Ichigo's Quincy powers, throwing him into a nearby building with great force, and force Love Aikawa to summon his Hollow mask.

Enhanced Strength
Hollow Ichigo pushed back Kensei Muguruma with little effort and put all of the Visored on the defensive with brute force. It headbutted the manifestation and sent him flying.

Enhanced Speed
While in this state, Hollow Ichigo's speed increases greatly. After breaking free from a Kidō spell, he appeared behind Oko Yushima to attack him.

Extra Appendage
In his full Hollow form, Hollow Ichigo can grow a large, worm-like appendage from various locations on his body (during his Visored training it emerged from his arm, and during his fight against the manifestation it emerged from his chest). This appendage will try to consume Zangetsu's current target.

Enhanced Durability
In addition to advanced recovery powers, Hollow Ichigo is equally difficult to injure. After being elbowed and pushed back by Kensei, he got up and continued his assault. He can take multiple direct and close-range Hadō spells of at least mid-level completely unfazed.

New Hollow Form
Ichigo later has his body taken over by Hollow Ichigo once again. This time, the full transformation is very physically different in appearance, and far more powerful than the previous one. In this form, Ichigo has long straight hair, reaching down to his waist, and a Hollow hole, smaller than his previous one, decorated with markings stretching from the hole across his chest and shoulders. He has retractable claws on his fingertips and toes, small, furry red tufts, two starting from his collarbone and stretching around his neck and one each on his wrists and ankles, and white skin.

In this new form, he has a different Hollow mask. It covers Ichigo's entire head, and its markings are different, for it has four spike-shaped marks, two of them stopping by the forehead and the other two stretching past the eyes and teeth, going past his chin and joining with the marks on his chest. There are small marks resembling a heart, but with the top and bottom open, extending from the inner corners of his eyes. The mask features two long forward-pointing horns, with black strips extending from their center towards the tips. Hollow Ichigo has his own version of this form, with the opposite colors alternating black with white and vice versa.

Chain
(チェイン, chein): After transforming, Hollow Ichigo called his Zanpakuto to his hand with a simple gesture.

Immense Strength
In this form, Hollow Ichigo can destroy a large portion of Las Noches' roof with the wake of a single slash of his sword. He easily tore off Ulquiorra's left arm without much resistance from his Hierro. He crushed Ulquiorra's strongest attack, Lanza del Relámpago, and forced it to collapse before Ulquiorra even got a chance to throw it. He easily slashed Ulquiorra from his left shoulder to his lower right hip through his Hierro. He can effortlessly throw a large portion of rock with a single hand.

Immense Durability
Hollow Ichigo's durability has greatly increased, allowing him to withstand several large explosions in his battle with Ulquiorra at close range with no visible damage. His skin and hands are strong enough to catch and hold onto Ulquiorra's strongest attack, Lanza del Relámpago, without any damage inflicted on him.

Sonído
Hollow Ichigo moves at exceedingly fast speeds, appearing behind Ulquiorra and throwing hissevered arm at him before the former could even turn to face him. Ulquiorra states his speed is not reached by the use of Shunpo; he actually uses Sonído.

Enhanced Spiritual Power
Hollow Ichigo's already vast Reiryoku increases drastically, easily overwhelming the power of Ulquiorra's second Resurrección. The sheer strength of his Reiatsu terrified Rukia Kuchiki, Renji Abarai, and Yasutora "Chad" Sado at the bottom of Las Noches.

High-Speed Regeneration
After Ulquiorra shatters Ichigo's mask, the energy from his Hollow transformation went above him and came down as some sort of energy, which regrew the lost flesh which made his Hollow hole (as a result of Ulquiorra's Cero Oscuras) and fully healed him of his injuries from Ulquiorra, who commented on it to this effect.

Zangetsu
(斬月, Slaying Moon) Since the inner Hollow Ichigo inherited from his mother fused with his original Shinigami powers, Ichigo's inner Hollow is also his Zanpakuto spirit. Hollow Ichigo and the manifestation of Ichigo's Quincy powers are both the source of Ichigo's power and share the same spiritual body in Ichigo's inner world, the stronger presence retaining more control (and overall appearance) of their body. Hollow Ichigo takes the form of an all-white (clothes and being), somewhat deranged version of Ichigo's Shinigami form with a strong desire to take control of Ichigo's body and power for himself. Zangetsu originally used a black Zangetsu obtained from the manifestation. However, after he becomes the dominant spirit inside Ichigo's mind, Hollow Ichigo carries his own white version of Ichigo's Zanpakuto.

Shikai
The Shikai form of Hollow Ichigo resembles an oversized khyber knife. It has no tsuba and no proper hilt; what Hollow Ichigo holds is the cloth-wrapped tang. The sword is as long as Hollow Ichigo is tall (1.75 meters), and has a silver blade with a black edge. The cloth wrapping on the tang seems to react to Hollow Ichigo's will, changing length at a thought or twining about the blade in an impromptu sheath. When in combat, the cloth falls away when necessary, shrinking back to a manageable size. The cloth can be used to swing the weapon like a flail and toss it at opponents for mid-range combat, and can wrap up wounds.

The wide blade can be used as a shield from incoming attacks. Unlike most Zanpakuto, which can be sealed into their original form, the blade is always in its Shikai form. Yoruichi Shihoin states this Zanpakuto is a full-time released form type because of Ichigo's vast but uncontrollable Reiryoku upon generation of it.

Shikai Special Ability
While primarily used for melee combat, the blade possesses a special ability.

Getsuga Tensho
(月牙天衝, Moon Fang Heaven-Piercer; "Piercer of Heaven" in the English version): At the instant of the slash, the blade absorbs Hollow Ichigo's Reiryoku and releases highly condensed Reiatsu at the tip of the blade, which magnifies the slash attack and flies forward. This slash takes the form of a crescent moon or the shape of a wave. When Hollow Ichigo uses this technique, it is red in color, while in the physical world, it is black in color with a red outline.

Bankai
Tensa Zangetsu (天鎖斬月, Heaven Chain Slaying Moon): It is considered completely out of the ordinary for any Zanpakuto. Unlike most Bankai, which usually create some sort of massive creature or effect, Hollow Ichigo's Bankai actually shrinks his sword down to a daitō (Japanese long sword) with a white blade, crossguard, and handle instead. The crossguard has four prongs bent out to form the shape of the manji (which is the kanji for "ban," meaning "full", as in "full release"). The blade itself is durable enough to withstand even the strongest of attacks, making it quite effective in blocking and deflecting incoming attacks.

It can withstand getting crushed by force. Instead of the cloth Hollow Ichigo's Shikai had, a short length of chain with a broken link at the end dangles from the base of the hilt. The chain can be used to spin the sword with one finger. In addition to his sword, Hollow Ichigo's robe is replaced with a long-sleeved, ankle-length white coat (or shihakusho) with black lining which is closed at his chest and left to flare out into ragged ends, much like the manifestation's, except the manifestation's shihakushō is black in color. Zangetsu wore a black shihakushō after Ichigo stabbed him, causing his white shihakushō to turn black.

Bankai Special Ability
Tensa Zangetsu, much like its Shikai form, is used heavily for melee combat, but possesses a certain special ability.

Enhanced Getsuga Tensho
Tensa Zangetsu retains the use of Getsuga Tensho, which can be used in the same manner, but in an enhanced form. When used in Bankai, these potent blasts, white with a red outline, can have their path controlled, and possess explosively augmented power and speed. When Hollow Ichigo uses this technique in the physical world, it is black in color. During Byakuya Kuchiki's fight with Ichigo, Byakuya refers to this attack as a "Kuroi Getsuga" (黒月牙, Black Moon Fang), referring to the attack's darkened color. Both Ichigo and Hollow Ichigo have stated the Kuroi Getsuga was originally the latter's technique.

Hyper-Speed Combat
Hollow Ichigo takes all the power of his Bankai and compresses it into a small, condensed form, which allows him to perform high-speed combat. His new speed allows him to move behind a Shunpo master like Byakuya and attack him. He can appear in front of a Shunpo expert like Ichigo, leaving no time to react.

Enhanced Strength
His physical strength increases greatly, shattering Byakuya's Senkei sword with his bare hand, and throwing Ichigo into a building, giving him a serious wound to his forehead as a result.

Enhanced Durability
Unlike Ichigo, Hollow Ichigo took a short time to recover and did not get wounded after being thrown into a building. He can deflect Ichigo's Bankai-enhanced Getsuga Tensho with a single unarmed hand.

Enhanced Spiritual Power
His Reiatsu is so intense and rough, as well as thick and heavy, it can suffocate Humans just by being in the general vicinity of his released Bankai, and easily surpass Byakuya's Reiatsu. His Reiatsu is solid in his Bankai, despite him only recently acquiring it. While in Bankai, Zangetsu's Reiatsu turns white, with a red outline.

Enhanced Bankai Duration
Since all of his energy is compressed, usage of his Bankai does not expel as much Reiatsu as other Bankai from the point of activation, allowing him to use Tensa Zangetsu for a much longer duration than any other Bankai users of his level.

Merged Form
After the manifestation of Ichigo's Quincy powers pulls Zangetsu out of Ichigo during the latter's Dangai training, the two spirits merged into one form, which combined aspects from both spirit's appearances; Zangetsu's white Bankai coat, black horn mask remnant, white-colored hair, and left Hollowfied eye alongside the manifestation's appearance, right blue eye, and black Bankai sword, though the sword's tsuba is white like Zangetsu's. In this form, the manifestation explains he and Zangetsu were technically two parts of the same being, with both of them together representing all of Ichigo's spiritual powers. Ichigo claims if this merged spirit really wanted to, he could have defeated him from the start of their battle, further stating they were this far apart in power.

Enhanced Strength
The merged spirit is strong enough to break Ichigo's Bankai sword completely in two.

Agent of Shinigami arc
While Ichigo Kurosaki underwent training to gain his own Shinigami powers, Kisuke Urahara puts Ichigo's soul through a process called Encroachment, where if Ichigo does not gain Shinigami powers on his own, he will become a Hollow. Tessai Tsukabishi severs Ichigo's Chain of Fate. Tessai uses Bakudo #99, Part 1. Kin to prevent Ichigo from using his arms to scale the sides of the shaft.

After three days in the shaft, Ichigo begins to transform into a Hollow. When the Bakudo restraining Ichigo begins to break, Tessai uses a more advanced version of it. When Jinta Hanakari says it will kill Ichigo, Tessai states he must restrain him before he completes the transformation into a Hollow. Before the final part of the spell strikes him, Ichigo escapes in the large explosion created by the awakening of his Shinigami and Hollow powers. Although he succeeds in gaining his power, he emerges from the pit with Shinigami robes and a Hollow mask, the latter of which he later discards.

Soul Society arc
During Ichigo's more difficult battles, the mask he thought he discarded kept reappearing on his body in places where there would normally have been fatal wounds.

As Ichigo fights Renji Abarai, Renji uses Zabimaru to hit Ichigo near his heart, but the sword is stopped for some reason. After the fight, as Hanataro Yamada heals Ichigo, he discovers the Hollow mask Ichigo thought he threw away was what blocked Zabimaru. Thinking of the mask as a good luck charm, Ichigo wants to keep the mask, but Hanataro, fearing it, takes it and throws it into the sewers.

Later, Ichigo runs into 11th Division Captain Kenpachi Zaraki, who stabs him in the chest. Seemingly dying, Ichigo is pulled into his inner world by the manifestation of his Quincy powers, where he meets Zangetsu for the first time. Explaining it is time to see if Ichigo is worthy of using him, the manifestation tells Ichigo if he wants to wield him again, he must take him back with his hands, for his opponent will be himself. Ichigo is forced into a fight with Zangetsu with a nameless katana while the latter has Zangetsu. Gaining an advantage, Zangetsu exerts his Reiatsu and begins to spin Zangetsu by its cloth. As the two fight, Zangetsu asks Ichigo if he thought it would be so simple to fully control his Zanpakutō and notes Ichigo only thinks about himself and never considered drawing out the power of Zangetsu. Zangetsu further explains there is more to the power of Zangetsu, and if he can open up and lend it his power, it will become even stronger. Stating Ichigo does not do this or rely on his Zanpakutō and only worries about making himself stronger, Zangetsu says it is time to end this. Deciding to show Ichigo the right way to use Zangetsu, he moves to attack. As they cross swords, Zangetsu is surprised to find the nameless katana in his hands and Ichigo holding Zangetsu. Seeing the manifestation has decided Ichigo is worthy of using him, Ichigo awakens back in the real world.

As Zangetsu stands there with a broken katana, still somewhat confused, he asks the manifestation if Ichigo is gone before asking him if that was all. Telling him it is, the manifestation says he is sorry to have bothered him. Zangetsu tells him it was no problem, for it would be problematic if Ichigo, the owner of the inner world, did not win; even though he was unwilling, he had to help. Asking for the manifestation to send him back, Zangetsu begins to fade away and tells the manifestation to train Ichigo well, for one day, this power will be his.

In the real world, as Kenpachi and Ichigo prepare for their last strike, Kenpachi's Reiatsu takes the form of a skull, while Ichigo's takes the form of his Hollow mask, showing how Zangetsu is supporting him.

After the battle, Yoruichi Shinoin takes Ichigo to heal him. As he awakens, she comments on how a Hollow mask saved Ichigo's life. Surprised, Ichigo mentions how Hanatarō threw it away, prompting Yoruichi, with a concerned look of fear, to get rid of the mask, much to Ichigo's dismay.

During the battle with 6th Division captain Byakuya Kuchiki at the execution grounds, Ichigo is pushed into a corner, and as Byakuya prepares to deliver the final blow, Ichigo is possessed by Zangetsu. As Byakuya swings his sword down, Ichigo catches it with his bare hand and starts speaking to himself. When Ichigo looks up, a mask is forming over the upper left half of his face, much to Byakuya's surprise. When Byakuya asks how this is possible and who he is, Zangetsu states he is nobody and slashes Byakuya down his torso.

As Byakuya puts some distance between them, Zangetsu comments on how weak Ichigo is and states his inexperience with the Reiatsu and speed of his own Bankai made his bones shake like crazy. Crushing the sword he grabbed from Byakuya, he states he will show Ichigo how to use a Bankai correctly. As Byakuya calls another sword to his hand and prepares for another attack, Zangetsu fires a Getsuga Tenshō. Using Shunpo to move behind Byakuya, Zangetsu fires another one before appearing directly behind the Shinigami captain before the two attacks meet. As they both survive the explosion, Byakuya notes the Reiatsu and the mask are akin to a Hollow's and asks what he is. As Zangetsu tells him not to worry about it because he will soon disappear, before he can finish his sentence, Ichigo regains control and rips the mask off. Telling Ichigo he cannot win without him, Zangetsu is pulled into Ichigo's inner consciousness as the fight nears its conclusion.

Bounts arc
Zangetsu keeps quiet for a time, only manifesting himself to fight Gō Koga and his doll, Dalk, before being forced back. Ichigo felt Zangetsu's influence growing over him. He slightly manifested himself for an instant (only Ichigo's eyes turned yellow; the mask itself never began to form, and the sclera of his eyes did not turn black) during Ichigo's fight with Jin Kariya, scarring him with a black Getsuga Tenshō, but Ichigo regains his senses shortly afterward.

Arrangcar arc
Ever since the fight against Byakuya, the mask does not come back, and eventually disappears. From that point on, Ichigo can hear Zangetsu calling out to him, and around the time of Arrancar invasion, he feels Zangetsu's influence dangerously growing over him. During Ichigo's fight with Yammy Llargo, Zangetsu interrupts Ichigo's thought process and tells him to call upon him for help, for he can make quick work of the two Arrancar, including Ulquiorra Cifer. This interruption costs Ichigo the fight, and most of his friends are seriously injured.

Later, when Ichigo confronts a Hollow to regain his fighting confidence, he feels Zangetsu trying to take over for an instant, which leads him to be punched by the Hollow. During another Arrancar invasion, Ichigo ends up fighting Grimmjow, and is subsequently forced to use a black Getsuga Tensho, which is one of Zangetsu's moves, making it easier for him to take over. Though he turns one of Ichigo's eyes black, Zangetsu is overcome by Ichigo.

Ichigo finds the Visored, and as he fights Hiyori Sarugaki, Zangetsu starts to take control again and almost kills Hiyori before her fellow Visored subdue him. Seeing the uncontrollable power of Zangetsu, the Visored agree to train Ichigo to control him. As Shinji Hirako knocks Ichigo unconscious and has Hachigen Ushōda place a barrier around the building, Ichigo confronts Zangetsu in his inner world.

When Ichigo asks where the manifestation is and takes out his sword, Zangetsu asks him if he is already carrying Zangetsu. Revealing he has his own white Zangetsu, he claims he is Zangetsu. The Visored take Ichigo's body down to an underground training area and take turns battling Ichigo's body, which is possessed by Zangetsu.

In the inner world, as Ichigo persists in asking Zangetsu where the manifestation is, Zangetsu explains he is Zangetsu; he and the manifestation were originally one being, for both are the source of Ichigo's power, and Zangetsu was part of the manifestation. Stating even though they both share one physical body, the form changes if the master and servant exchange roles, Zangetsu reveals control was transferred to him as his power grew, and the manifestation became a part of him, so the more Ichigo tries to draw out Zangetsu, the easier it becomes for Zangetsu to take over Ichigo's soul. Realizing the manifestation will be put back into control if Zangetsu is defeated, Ichigo activates his Bankai and is surprised to see Zangetsu possesses the ability to use Bankai.[46] Gaining a white Tensa Zangetsu, Zangetsu explains he obtained it when Ichigo did. As the two battle, Ichigo fires a Getsuga Tenshō. Batting it away as if it were nothing, Zangetsu unleashes his own highly powerful white Getsuga Tensho.

In the real world, Lisa Yadomaru fights the possessed body of Ichigo and switches places with Kensei Muguruma. Battling him, Kensei stabs him with his Shikai. When Kensei uses his Shikai's special ability, Ichigo's body begins to undergo serious Hollowfication and becomes a reptilian-looking Hollow.

In the inner world, Ichigo has been heavily injured, and Zangetsu explains how he is the first user of the Bankai version of Getsuga Tenshō and taunts Ichigo about his lack of skill. Moving close to Ichigo, he grabs his Tensa Zangetsu and turns the blade white while telling him he cannot use Bankai, destroying his sword.[50] Attacking the now defenseless Ichigo, Zangetsu explains his reasoning for his ascendancy to power and what true power between two beings really is. Stabbing Ichigo in the stomach with Tensa Zangetsu, he tells him he will no longer be the servant of someone weaker than him, and now he will be in control. Gaining his will, Ichigo grabs the sword in his stomach and transforms it into his black version. Pulling out the sword, Ichigo attack the now defenseless Zangetsu by impaling him through the stomach. As Zangetsu's clothes become black like Ichigo's, he begins to disintegrate into the wind. Before Zangetsu totally disappears, he reminds Ichigo he concedes to his control only for now, and one day, given the smallest opening, he will take control and destroy Ichigo. He tells Ichigo if he truly wants to master his power, he must stay alive.

As Love Aikawa begins to fight the fully Hollowfied Ichigo, he realizes the battle is going to be tough. Zangetsu charges up a Cero, but before he can unleash it, his body begins to break apart, resulting in an explosion of Reiatsu. When the smoke clears, Ichigo, wearing his Hollow mask, comes out of the husk of what is left of the full Hollow form. As the husk falls to the ground and shatters, Shinji has Hachigen bring down the barrier, and Ichigo falls as his Hollow mask falls off.

The New Captain Shunsuke Amagi arc
Zangetsu appears during Ichigo's final fight with Shusuke Amagai, but most of the time, he only manifests as Ichigo's power source for his Visored mask. During the battle, he grins in Ichigo's mind.

Zanpakuto Unknown Tales arc
Upon battling Ichigo, the rogue Zanpakutō spirit Muramasa draws out the manifestation from Ichigo's being. Without the manifestation in the way, Zangetsu easily gains control of Ichigo's body. When he takes over the fight, the manifestation is quickly brought to his fighting limit. Although the manifestation manages to injure him, his High-Speed Regeneration heals the wounds, and he assumes his full Hollow form. Fearing this new development, Muramasa begins to attack Zangetsu, but is effortlessly driven back. Ichigo manages to regain control of his body and removes his Hollow mask, returning his normal self, before passing out in exhaustion.[56]

Determined to find out the truth behind Ichigo's unique powers, Muramasa enters Ichigo's inner world to try to forcibly draw out Zangetsu. Upon finding him, Muramasa asks what he is, and Zangetsu states he is Ichigo's purest instincts. When Muramasa attempts to take control of Zangetsu by "freeing" his true desires, a smirking Zangetsu attacks him.[2]

Caught by surprise, Muramasa is quickly forced into an all-out fight. Zangetsu proves to be superior in both speed and strength, forcing Muramasa to instead rely on his invisible binding powers to restrain him like he restrained Ichigo. Breaking free from his bonds, Ichigo saves Zangetsu and states Zangetsu is a part of him too. As both Muramasa and Zangetsu express shock at Ichigo's actions, Ichigo states while he would be happy for Zangetsu to leave him, he is still a part of Ichigo. Forcing Muramasa out of his mind, Ichigo continues the fight in the outside world.[57]

When Ichigo is forced to fight Zangetsu using his Bankai, Zangetsu offers his assistance, for he is free of the manifestation's influence, so Ichigo cannot draw on his power at all without Zangetsu's consent, meaning Ichigo would have to fight without his Hollow mask to suppress Zangetsu. As a battle of the manifestation's Getsuga Tenshō and Ichigo's Getsuga Tenshō ensues, Ichigo accepts Zangetsu's help. Ichigo overwhelms the manifestation with the combined power of his Getsuga Tenshō and Zangetsu's Getsuga Tenshō, defeating Muramasa and freeing the manifestation from Muramasa's control.[58]

Fake Karakura Town arc
During Ichigo's final battle with Ulquiorra Cifer, the latter seemingly kills him with a point-blank Cero Oscuras through his chest. As Orihime Inoue tries to heal Ichigo while Uryu Ishida holds Ulquiorra off, there seems to be no change in Ichigo's state. After Ulquiorra defeats Uryu, Orihime begins to panic and frantically begs for Ichigo to help her. She fails to notice Ichigo's hair growing longer and beginning to resemble a mane. As Ichigo tells his body to stand up, Zangetsu takes over and transforms Ichigo's body once more.

Shocked at his enemy's unexpected revival and believing Ichigo to be dead, Ulquiorra demands to know who he is. Summoning his sword to his hand without touching it, Zangetsu answers with a roar. Believing words are useless, Ulquiorra fires a Cero Oscuras, but to his surprise, Zangetsu fires a Cero powerful enough to counter it. As Ulquiorra refuses to believe a Human could release a Cero, especially one capable of blowing away his own, Zangetsu appears behind him and effortlessly rips off Ulquiorra's left arm.

Quickly regenerating the arm, Ulquiorra reveals his true power is not his offensive abilities, but his ability to instantly regenerate any non-vital body part. Resorting to using Lanza del Relámpago, Ulquiorra tells Zangetsu to stay right where he is because he does not want to risk using it at close range. When the attack misses, creating a massive explosion in the desert, Ulquiorra states to himself it is a difficult technique to control. As he prepares a second spear, Zangetsu appears next to him, startling Ulquiorra because he used Sonído instead of Shunpo. When Zangetsu throws the detached arm at him, Ulquiorra slashes it away and thrusts the spear. Catching it with a single hand, Zangetsu crushes it. Ulquiorra is left dumbfounded, allowing Zangetsu to slice him down the torso and slam him to the ground. As Ulquiorra states he cannot believe he was defeated by a Human turned Hollow, Zangetsu steps on Ulquiorra's head and begins charging a Cero. Commenting on how Zangetsu shows no mercy, something very Hollow-like, Ulquiorra states because Zangetsu has beaten him, he has no reason to live, and tells him to do it. Zangetsu releases the Cero, creating a vast and powerful explosion on the dome of Las Noches.

Ulquiorra survives, but his left arm, both legs, and lower torso are blown away in the blast. Tossing his tattered body aside, Zangetsu prepares to impale his throat with his sword. Attempting to stop Zangetsu from carving up the apparently dead body of Ulquiorra, Uryū states he will no longer be Human if he goes through with such a merciless act, which prompts Zangetsu to throw Tensa Zangetsu at him, stabbing Uryū through his stomach and sending him flying a distance away. Just as Zangetsu is about to attack Uryū with a point-blank Cero, Ulquiorra, having partially regenerated, severs one of Zangetsu's horns, causing his Cero to disperse skyward.

The explosion shatters Ichigo's mask, and he falls to the ground. As his body and leg begins to regenerate, Ulquiorra thinks to himself it is merely a front, for his internal organs were decimated from Zangetsu's Cero and cannot regenerate. Though he believes Ichigo is finally dead, the hole in Ichigo's chest completely repairs itself, and Ichigo gets up, shocking Ulquiorra with his ability to use High-Speed Regeneration.

Later, when Ichigo is fighting the manifestation in his inner world, the manifestation makes his way to Ichigo and rips Zangetsu out of Ichigo's body. When Ichigo sees Zangetsu, he is in his Bankai state as well, but he is now wearing a black mask with horns and white lines stretching vertically across the eyes. Greeting Ichigo, who is shocked by his sudden appearance, Zangetsu removes his mask and asks if he recognizes him.

Wondering how Zangetsu is standing before him, Ichigo states he should have disappeared when Ichigo defeated him while training with the Visored. Zangetsu reminds Ichigo how he said that if he wanted to control his power, he should not die before his return. When Ichigo states he was trying to crush him out back during his training, Zangetsu says it is unfortunate, since he is still around. When Ichigo asks him why his appearance changed, the manifestation informs him he took this form when he killed Ulquiorra and states Ichigo fears this form, for the destructive power overwhelms his heart to the point where he cannot even Hollowfy properly. When Ichigo concludes he has to fight Zangetsu and win, the manifestation tells him this is incorrect, for Ichigo is going to fight both of them in a one-on-one fight. They begin to fuse together, much to Ichigo's confusion, and take on a new form. Upon fusing, they take on a hybrid appearance: Zangetsu's white Bankai coat, black horn mask remnant, white-colored hair, and left Hollowfied eye, alongside Tensa Zangetsu's appearance and black Bankai sword. Stating they are two parts of a single being, the source of Ichigo's power, they begin fighting him.

Cutting Ichigo's own Tensa Zangetsu in half, the merged spirit throws Ichigo into a building and notes Ichigo still will not fall. When Ichigo says he will not fall until he learns Saigo no Getsuga Tenshō, the merged spirit states he does not intend to teach it to Ichigo and charges at him. Much to the merged spirit's surprise, Ichigo lets go of his blade and allows himself to be stabbed. The spirit states it was smart of Ichigo, but Saigo no Getsuga Tensho is not a technique which can merely be acquired by accepting his blade. Beginning to shed tears, he asks Ichigo if he remembers earlier in the battle when he said what Ichigo wanted to protect was not what he wanted to protect. Stating what he wants to protect is Ichigo, he reveals the meaning will come along with the essentials of Saigo no Getsuga Tensho. Telling Ichigo he will lose his Shinigami powers if he uses Saigo no Getsuga Tensho, the merged spirit bids Ichigo farewell.

The 10 Thosand Year Blood War arc
Upon returning to Ōetsu Nimaiya's palace, the Asauchi which Ichigo chooses takes on the form of Zangetsu. Later, during the forging of Ichigo's new Zanpakuto, Nimaiya reveals this happened because Zangetsu is Ichigo's real Zanpakutō, for the inner Hollow inherited from his mother fused with his Shinigami powers and became his Zanpakutō.

When Ichigo confronts the manifestation in his inner world, the manifestation reveals he always used the powers of Zangetsu to teach Ichigo how to use his Zanpakutō, and Zangetsu was always the one to save Ichigo's life, but the manifestation did not want Ichigo to become a Shinigami, so he suppressed Zangetsu and became Ichigo's primary source of power. After gaining access to the full power of his Zanpakutō, Ichigo states he believes both Zangetsu and the manifestation are Zangetsu. Upon gaining his new Zanpakutō, Ichigo realizes the larger blade represents Zangetsu, while the shorter blade represents the manifestation.

Quotes

 * (To Ichigo Kurosaki) "What are you doing, partner? If you just stand there... I'll kill you!"
 * (To the manifestation of Ichigo's Quincy powers) "He's strong... Zangetsu... train him well... because one day, that power will become all mine."
 * (To Byakuya Kuchiki) "Who am I? I have no name!"
 * (To Go Koga) "Who am I? How can you ask such a stupid question? I am who I am!"
 * (To Ichigo Kurosaki) "I'm going to keep getting closer and closer to you. And not just day after day, oh no. It's going to happen much faster than that! See I'm already closer to you than I was a moment ago. And I'll keep getting closer and closer to you, until I swallow you up and then, you'll disappear. Things are not turning out well for you at all, are they? (laughs) See you around."
 * (To Ichigo Kurosaki) "That "Zangetsu" thing you're talking about... aren't you holding it right there? Or maybe... could it possibly be the one... that I have here?"
 * (To Ichigo Kurosaki) "I am... Zangetsu!"
 * (To Ichigo Kurosaki) "Ichigo, I don't know if you understand or not,...but, Zangetsu and I have always been one and the same. Both Zangetsu and I are a part of your spiritual power, and I was apart of Zangetsu! We all share the same body, and whenever the 'dominant' person changes, the outer appearance also changes. When one is dominated by 'life', one is flesh. When one is dominated by 'death', one becomes bones. It's the same reasoning. My power expanded, and so the ruling power went to me. And this way, Zangetsu became a part of me instead. The more you try to use Zangetsu's power, the easier it is for me to control your soul!"
 * (To Ichigo Kurosaki) "Ichigo, what's the difference between a king and his horse? I don't mean kiddy shit like "One's a person and one's an animal" or "One has two legs and one has four." If their form, ability and power were exactly the same, why is it that one becomes the king and controls the battle, while the other becomes the horse and carries the king?! There's only one answer. Instinct! In order for identical beings to get stronger and gain the power they need to become king, they must search for more battles and power! They thirst for battle, and live to mercilessly, crush, shred, and slice their enemies! Deep, deep within our body lies the honed instinct to kill, and slaughter our enemies! But you don't have that! You don't have those pure, base instincts! You fight with your brain. You try to defeat your enemies with logic! And it doesn't work! You're trying to cut them with a sheathed sword! That's why you're weaker than me, Ichigo!"
 * (To Ichigo Kurosaki) "I'm not gonna have it, Ichigo. I don't know about Zangetsu, but I refuse to carry a king who's weaker than me and get cut to ribbons with him. If you're weaker than me, then I'll destroy you, and take your crown for myself."
 * (To Ichigo Kurosaki) "Shit. Looks like your instincts, and your desire to fight, aren't completely gone. Guess there's no way around it. You got me. I have to recognize you as the king, for now. But don't you ever forget! Don't forget that either one of us can become the king or the horse. If you ever give me the chance. I'll drag you down and crush your skull! And one last warning. If you really want to control my power, make sure you don't get yourself killed before I come back!"
 * (To Muramasa) "What am I? I'm his true form. I guess you could say I'm his instincts."
 * (To Muramasa) "I'm gonna devour Ichigo and take over his body for good. That's my instinct."
 * (Before helping Ichigo defeat Zangetsu) "Well, there's no point if my landlord's gonna croak."
