Allen Walker
(アレン・ウォーカー) Seiyū: Sanae Kobayashi
Allen Walker is an Exorcist of British origin and the main protagonist of the series. He is polite and gets along well with everyone he meets, the exception being Yu Kanda.(He seems to fight with Kanda everytime he sees him) He is apparently cheerful, smiling quite often. He is also quite empathetic, caring about the souls of the akuma he sees with his cursed left eye, as well as becoming an Exorcist for his foster father, Mana Walker. His true surname is unknown. It is shown that he once only cared about the akuma, and that they were the only thing precious to him, but that he changed and truly cared about the people he met in the Black Order. In the flashback revealed in Chapter 166, Allen was once very rude, talking bitterly against adults, and worked at a circus doing odd jobs, he stated that he didn't want friends, but still cried when Mana's dog died.
Allen is an orphan who was abandoned by his biological parents because of the supposed deformity of his left arm. He was eventually found and adopted by Mana Walker on Christmas Day. Though the circumstances were never revealed (though the anime supplies one possible cause with a scene of an overturned carriage), Mana died, and Allen, tormented with grief, turned Mana into an Akuma, hoping that his beloved surrogate father would be fully resurrected. But the Mana Akuma cursed Allen and sliced through his left eye, leaving the "Pentacle" -- the mark of the Akuma -- which scars the left side of his face and turns his hair white from his original brown hair. This enabled his left eye to see the souls trapped within the Akuma from then on. It was at this same moment that Allen's left arm first invoked as an anti-Akuma weapon, which instinctively destroyed the Mana Akuma.
Allen eventually met Cross Marian, a general of the Black Order, who explained to Allen the ways of the Akuma and the trapped souls within them: Once a soul becomes trapped inside an Akuma, they are trapped forever; and that the only way to save one is to exorcise them from their Akuma vessel. Allen subsequently became Cross' disciple and spent the next three years with him before being sent to the Black Order to become an official exorcist.
In chapter 160, the infected Matron bit his left arm. However, the effect of the bite, which would have turned him into a zombie-type creature, was slowed. This is possibly due to his Innocence. Despite this, Allen states he's "feeling a little weird" and is showing obvious physical signs of the zombie state, typically veins around black eyes. Even so, it appears he's consciously trying to suppress the virus due to his pride as an English gentlemen.
In Chapter 162, Allen, Lavi, Kanda, Komuirin EX and Johnny are hiding in a storage room and Krory knocks on the storage's door and try to get in, though they don't think he can be trusted. Allen, Kanda, and Lavi think that Komuirin X should have to do it, though he refuses. Allen then in a "girlish way", succeeds in provoking Komuirin EX into doing it. They then found out that Krory was the origin of the infection and now have a chance of getting a vaccine.
Unlike other characters of the series Allen's skills and powers are not just one thing which are as followed:
Crown Clown: The Innocence of Exorcism Allen's anti-Akuma weapon, initially unnamed, is a rare, parasite-type Innocence that shares a symbiotic relationship with Allen's body. It appears as a cross-shaped shard embedded in the back of his left hand, which causes his entire left arm to appear red, scaly, and deformed. As a parasite-type, it is capable of both invoking and acting of its own accord, such as when it destroyed Mana's Akuma or regenerated the portion of Allen's heart that was hollowed out by Tyki Mikk's Tease.
Due To the unique nature of parasite-type Innocence, Allen's Innocence has undergone a series of "evolutions" based on Allen's synchronization ratio. The first and most basic form of Allen's Innocence augments his left arm into a monstrous adamantine claw with a supernatural glow at Allen's shoulder. At this phase, his Innocence is capable of manipulating its size and shape. Despite the magnitude of size it can achieve, it retains a phenomenal degree of speed and reaction, making it an extremely versatile anti-Akuma weapon when engaging Lv 1 Akuma. The next evolution of his Innocence occurred during Allen investigation of "The Ghost of Mateel". This evolution takes a more offensive approach, in the form of a massive arm-cannon. This form is capable of ranged and melee combat; a contrast to the defensive nature of his Innocence's first form. This second phase can switch between two modes, a cannon mode and a rod mode. Below is a listing of abilities Allen is capable of invoking between these two phases:
• Cross Grave (十字架ノ墓（クロス・グレイヴ） Kurosu Gureibu): At the first level of invocation, the Innocence's power can be channeled into one powerful stream, capable of crucifying and destroying multiple Lv 1 Akuma simultaneously.
• Cross Paling (十字架ノ杭（クロス・バリング） Kurosu Baringu): At its second phase of invocation, Allen's Innocence is capable of firing volleys of rod-shaped energy palings; these laser stakes are made of hard-light Innocence energy, which enables them to picket the ground and fence in the adversary, or to pile upon them; Allen may also stand atop the palings. This ability is often translated as "Cross Beam".
• Cross Spear (十字架ノ槍（クロス・スピアー） Kurosu Supiā): Also in its second phase of invocation, Allen is capable of focusing the barrel of his Innocence-cannon to generate a spear-like energy paling, which can then be used like a sword. This ability is often mistranslated as "Cross Blade".
Allen's synchronization ratio reached a maximum of 84% before having his Innocence destroyed by Tyki Mikk. Yet unbeknownst to Allen, the Innocence lingered around as a hazy fog of particles; at the time, a direct reflection of his shattered state of mind. It wasn't until he came to an epiphany that he was able to seize control of his anti-Akuma weapon once again and achieving his Innocence's fully-invoked form. When not activated, his arm is black with a tattoo near his shoulder and a red cross on the back of his hand. It was given its official name of Crown Clown (神ノ道化（クラウン・クラウン） Kuraun Kuraun), due largely to the jester-like cowl and mask that appears when invoked. The kanji used in the name literally translates to God's Clown (神ノ道化 Kami no Douke)
In chapter 152, Komui calls Crown Clown a body-armour innocence, able to use Allen's body as a marionette to destroy akuma even when Allen's body is no longer fully operational. Crown Clown is also able to take control of Allen's body even if Allen is capable of fighting, though the latter happens if Allen is in the way of a dangerous attack. Both forms of control are symbolized by the mask on Allen's cowl fitting itself over Allen's face. When Crown Clown is in control, it seems to be more powerful than Allen, as it easily decimated Tyki Mikk's Tease with a flick of its cape. Allen's innocence also showed this ability during the Krory arc, but at that point all Crown Clown could do was invocate and attack. Crown Clown apparently shows some degrees of sentience during these times.
When invoked, Crown Clown drapes Allen in a long, white, ectoplasmic cowl, fitted with a masquerade-style mask that is silver, black [and gold, but only in the manga]. His left arm transforms into a slender, black arm fitted with silver, crown-shaped braces and rings, as well as razor-sharp talons, while his right arm and hand are encased in a sleeve and glove of the same ectoplasmic material as the cowl. The innocence can also use Allen's strength to repair itself as seen when it was severely damaged by Tyki Mikk, but managed to reform. It also becomes stronger when Allen's feelings merge with its own. This is observed when, after seeing it regenerate, Tyki Mikk feels his body beginning to die from being crushed by the Innocence's "spirit". When Allen forced his synchronization to a critical state, exceeding 100% synchronization, Crown Clown undergoes another evolution: Allen's entire left arm is transmuted into a massive zweihänder with a large cross emblazoned on the blade, with his left shoulder being capped with a cross emblem. Allen wields the sword with his free right hand and the Innocence cowl becomes a high-collared cape which covers his missing left arm, with the mask acting as a clasp across the chest. Below is a listing of Allen's abilities in between these phases of Innocence:
• Cross Grave (十字架ノ墓（クロス・グレイヴ） Kurosu Gureibu): Much more powerful than its previous incarnation, Allen crucifies and annihilates his targets by etching a cross onto them with his left hand, capable of destroying even Lv 3 Akuma with only a single talon. It can now also be used defensively, generating a shield by drawing a cross in the air.
• Clown Belt (道化ノ帯（クラウン・ベルト） Kuraun Beruto): The cape of Allen's cowl is released as a webbing of Innocence-energy that can be used to grasp objects, immobilize opponents, or form hardened spikes to impale enemies. It can also be released from the sleeve and glove on Allen's right arm. The webbing can also become ribbons to grasp onto railng or banisters. the ribbons were once used by Crown Clown itself to wrap around Allen's limbs and control him like a puppet when Allen was too injured to move himself.
• Crown Edge (爪ノ王輪（クラウン・エッジ）): A projectile attack which unleashes a barrage of crown-shaped rings from the clawed fingers on Allen's left hand. The kanji used in the name of this attack literally translates to "Claw of King-rings" (爪ノ王輪 Tsume no Ōwa).
• Edge End (破滅ノ爪（エッジ・エンド） Ejji Endo): A swipe of raw destructive power dealt with Allen's fully-invoked claw. The kanji used in the name of this attack literally translates to "Destruction Claw" (破滅ノ爪 Hametsu no Tsume).
• Sword of Exorcism (退魔の剣 Taima no Ken): The giant broadsword Allen's left arm transmutes into after he found out the true reason of his existent, left arm to save the akuma and the right arm help humans. Essentially, the Sword of Exorcism is an inversion of the Millennium Earl's sword, in both ability and appearance. The sword can be wielded like any other, though once invoked, the blade can exorcise evil from any vessel it strikes without any harm coming to the vessel itself if Allen chooses. Use against Akuma vanquishes them in the same effect as the Cross Grave attack, leaving a residual glowing cross crest in the awake of the defeated Akuma. However, in the case of level 4 Akuma the sword carries a diminished effect. Peculiarly enough, in the case of Noah, the Sword of Exorcism seems to unleash their powers in full rather than exorcise them.
The Cursed Eye of the Pentacle In addition to his Innocence, the Pentacle that scars his left eye curses Allen with the power to see the souls trapped inside an Akuma. The first incarnation of the curse is a black and red ringed eye which is automatically activated whenever Allen is near Akuma. Allen refers to his eye as "Mana" when it heals, evolves and a spirit is seen entering his eye.
However, during the vampire incident involving the Eliade-Akuma and Arystar Krory, Allen's curse had grown stronger, resulting in his eye undergoing some dramatic changes. Resembling a sort of cogwheel monocle, this new cursed eye enables Allen to pinpoint an Akuma's position even when they are not visible to the naked eye, regardless of obstacles, from a distance of up to 300
