Allen Walker

"With my right hand I will save humans, and with my left hand I will save the Akuma."

- Allen's eternal quest

Allen Walker is the main protagonist and member of the religious organization known as the Black Order, in the anime and manga series D.Gray-man, by Katsura Hoshino. He is the apprentice to Cross Marian.

Appearance
Allen is a short boy with white hair (from his earlier encounter with an Akuma). He has a scar running down his left eye and at the top is an inverted pentacle (also received from this encounter). Because of his Innocence, which is a cross embedded into the back of his left hand, his entire left arm is red and somewhat deformed. Allen wears the standard Exorcist uniform with a hood and gloves covering his hands.

Personality
Allen Walker is a polite, friendly and well-mannered teenager who does not back down from a challenge. The most obvious example of this is his confrontations with Yu Kanda, fellow Exorcist and polar opposite in personality. He is selfless, willing to sacrifice himself for someone he does not know very well or even like. He is also very loyal to those he loves, doing anything to save them, and is devoted to his cause almost to the point of self-harm. He treasures all life, vowing to save both humans and Akuma, but this often puts him at odds with other Exorcists.

His parasitic Innocence causes him to need vast amounts of food, to the point where it's more comical than anything else. This necessity often leads him to thinking about it even in serious situations, such as being trapped in the Noah's Ark, and the one thing he looks forward to upon getting out is eating. Another comical trait he has is his extreme dislike of being called short. Lavi and Kanda, but especially Kanda, call him "bean sprout" and he always reacts in an over the top agitated manner to it. This has sometimes even helped him out of life or death situations by giving him an extra boost of energy to retaliate, going so far as to give him a killing intent

The way he views the world is different from the other characters. Instead of letting the bad things get him down, he remains optimistic in any situation, largely due to his vow to Mana Walker to keep moving forward. No matter what obstacles he encounters, he will never give up.

What he experienced in his training with General Cross is largely a blank, but the result is quite clear. It has given him a 'black' side, the complete opposite of his normal personality, and only appears when he runs into something that he learnt from Cross (such as poker, gambling, or the debts left by Cross). He has once used this to discover the difference between two Arystar Krorys when Lulu Bell was impersonating one of them, causing the real one to cry.

History
Allen was abandoned by his biological parents because of the supposed "deformity" of his left arm (which was later revealed to be caused by his Innocence). He was eventually found and adopted by a traveling performer named Mana Walker on Christmas Day. Some time later Mana died, and Allen, tormented with grief and manipulated by the Millennium Earl, 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. 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. During the course of this traumatic event, Allen's hair turned from brown into a stark white.

Allen eventually meets 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 is brought back inside an Akuma, they are trapped forever; 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. During this time, Allen was tormented by his master's constant irresponsible behavior and forced into various odd jobs to pay off the debts that General Cross accumulated. This, coupled with Marian's womanizing ways and harsh treatment towards Allen, led to Walker fearing more than respecting his master whom he never speaks fondly of. In fact, when Jasdevi claims that Cross is like a demon, Allen denies this and instead insists that Cross is a real demon. In addition, when Jasdevi reveal that the debts Cross left them total about 2 million yen, Allen grows demon horns, laughs at them, and calls their debts small change in comparison to his own, leaving Lavi to wonder just how much money Allen's been made to pay.

In addition to being physically fit and skilled at combat (as evident by his ability to fight and dodge Fou without the use of his Innocence), Allen has a few odd talents and skills. Because of the many debts Allen was forced into paying by Cross, he learned to play cards and gamble at a very young age, though his initial purpose was to practice his paralyzed and deformed left hand. He also learned how to cheat and win through deception and doesn't hesitate to use these tactics whenever necessary. In fact, he is quite proud of his talents. This is a stark contrast to his polite and courteous nature and often surprises his friends, who wouldn't expect such a dark side to Allen, and has caused them to wonder just what Cross has done to him. Walker also possesses circus abilities such as juggling and acrobatics, which he learned from traveling with Mana who was himself a circus clown by trade.

Inspector Levrier and Cross have both referred to a "player" (as in one who plays a musical instrument), and Cross has hinted that there may be more than one.

Intro arc
Allen first appears in London and as soon as he arrives, a cat eats Timcampy. Chasing it, he arrives at a "haunted" church and saves a police woman, named Moore from an Akuma. He is soon suspected for her partner's death. However, as the investigation continued, Allen discovered that Moore's brother-in-law was the Akuma. After a brief fight, Allen kills the Akuma and leaves to the Exorcist HQ.

When Allen arrived at the order, the Gatekeeper mistook him for an Akuma because of the Pentacle mark on his eye and Kanda is dispatched to kill him. This miscommunication is straightened out after his letter of recommendation from General Cross was finally found on Komui Lee's cluttered desk. Upon his arrival, he met with Hevlaska and was predicted to be the "Destroyer of Time". The meaning of this is never really explained, but Bookman theorizes that "time" referred specifically to the "millennium" or even more specifically, the Millennium Earl. In essence, it is believed that this prophecy means Allen will be the one to someday destroy the Millennium Earl.

Lenalee Lee takes this opportunity to show Allen around as Allen meets many of the Order's members. He quickly became friends with the chef, Jerry, due to his huge appetite, and the Finders, because he stood up for them against Kanda.

Ghost of Mateel arc
Komui gives Allen his first assignment: find an Innocence in the town of Mateel. He is partnered with Kanda and a Finder named Toma. As they arrive, they find the Finders stationed there have been killed by three Akuma. Allen and Kanda quickly dispatch two of them; however, the last one evolves into a Lvl 2 Akuma. Allen gets beat up by the Akuma's ability to copy anything. The Akuma soon throws him into a building which knocks him out.

Later, Allen arrives just in time to stop Kanda from killing Toma. Later, he escapes with the others and finds the Ghost of Mateel, initially thought be Lala, with an old man (actually the Ghost). As he hears her plea to stay alive long enough to be with her dying friend Guzol, Allen agrees to wait for her friend to die before taking her heart. Kanda disagrees with such a "foolish" act. It is eventually revealed that Lala is a doll with an Innocence inside her that allows her to be "alive". As the Lvl 2 Akuma arrives, it takes Lala's Innocence heart and Guzol is gravely wounded. Allen becomes so enraged that he activates his Anti-Akuma arm into its evolved form, which becomes a cannon. With Kanda's help, the two kill the Level 2 Akuma. Allen then returns the heart to Lala and allows her to fulfill her promise to her friend before he dies. With this, Allen is allowed to take the Innocence back to HQ.

As Allen and Toma head back to HQ, Allen runs into the son of one of the Order scientists, John, who wants to kill Akuma. Allen and Toma try desperately to convince John to stop hunting Akuma to no avail. Allen then tries to get John's father Jake Russell to convince him, but he found that Jake was more interested in work than his family. Allen then gets a bad feeling and he goes back to John just as Lenalee is about to throw a Welcome Party for Allen. Allen finds that the Earl had turned John's friend Leo into an Akuma and as the two exchange ideals, the Earl remembers Allen was someone he had made an Akuma for as he summons several Akuma to take him out.

Not to be outdone, Allen and Lenalee attack the Earl and the several Akuma he summoned in a huge battle. Allen defeats them all but the Earl escapes and curses how he didn't kill Allen when he was younger. Afterwards, he goes back to HQ and gets attacked by Komui's newest robot, only to in the end be saved by Lenalee. Later, Lenalee takes Allen to his Welcome Party.

Rewinding Town arc
Allen and Lenalee are dispatched to a town in Germany that has been stuck on "October 28" for thirty days. Allen manages to save Miranda Lotto from an Akuma and soon the three meet three more Lvl 2 Akuma who leave under mysterious orders. Soon, Allen and Lenalee figure out that Miranda's clock holds an Innocence and that Miranda is the clock's accommodator.

After they've tried to help Miranda, Road Kamelot captures them and explains to Allen about the The Noah Family and their connection to the Millennium Earl. His injuries are temporarily healed by Miranda, who activates her Innocence. Allen and Lenalee then work together to defeat Road and her Akuma, but Road forces an Akuma to self-destruct, causing the trapped soul to be destroyed. Horrified, Allen tries to save the soul by killing the Akuma before it detonates but Lenalee stopped him from the possible death, forcing Allen to witness the soul's destruction. Enraged, he shouts as he asks why she stopped him, which leads her to slap him and exclaim that she is his friend so she couldn't watch him die. Road gets bored and is about to leave when Allen tries to kill her in angry anguish. In the end, he cannot do it. Allen and Lenalee then convince a distraught Miranda to stop her activation and let them regain their wounds.

While healing, Allen meets Lavi and the two become fast friends as he learns from Lavi how to live as an Exorcist without his pentacle, and is also reminded of the significance of the Exorcist's coat as once told to him by his master.

The Vampire from the Old Castle arc
Allen joins Lenalee, Lavi, and Bookman to find General Cross, much to his dismay. Allen was soon separated from the group as he publicly apologized to Lenalee about the exploding Akuma incident. Villagers, believing him to be a priest, kidnapped him to help them with a "vampire" problem. Lavi soon appeared with the others and went to help him as Lenalee warned Allen not to get bit by the vampire. He becomes shocked as he finds the vampire Baron Arystar Krory III. As Allen gets bit by him, Lavi keeps a stake and some garlic with him while chanting that Lenalee will never speak to him again.

As they enter the castle and run into Krory's man-eating flowers, Lavi spots Eliade and he instantly becomes smitten with her. Allen stopped him from trying to become her "lover" and the two fought Krory again. Before the fight however, Allen and Lavi discovered Krory has been killing Akuma instead of people. Allen battled Eliade as Lavi tried to convince Krory to join their side. As he fought her, Allen was knocked out and as he was about to be killed, Allen's pentacle evolved and saved him. Allen then figured out that Eliade was an Akuma. Krory was uninterested in joining them and after seeing Allen try to hurt Eliade, he threw both him and Lavi into the man-eating flowers. Realizing they only eat people with negative attitudes from Lavi, Allen helped proclaim feelings of love to the flowers like him so they could escape.

Finally freed, Allen converted Krory to the Black Order so he could have friends. He watched alongside Lavi as Krory burned down his castle to find a new life with his first friends. Sometime after traveling with them, Allen learns about Lenalee's recurring nightmare about the end of the world and him. After hearing this, Allen comforted her and promised to protect her and that he wouldn't die. On the train, Allen found that Krory lost everything he had in a poker game (he didn't know how to play) so Allen played to retrieve Krory's stuff. Allen, of course, cheated in poker as he explained that Cross taught him how to which makes Lavi and Krory worry about what Cross had done to him.

Edo arc
As his team moved to China to locate Cross, Allen learns from Cross's recent lover, Anita that he went to Japan. Allen and his team with Anita and the supporters of Black Order abroad Anita's ship to Japan. Allen soon discovered a huge wave of Akuma coming towards them and as he fought them both he and Lenalee discovered the Akuma's target wasn't them. They find that the Akuma are hunting Suman Dark, who has turned into a Fallen One, for his Innocence.

After hearing about Fallen Ones from Lenalee, Allen promised her that he would save Suman. As they tried to contact him, to no avail, Allen ended up getting absorbed into him as he saved a little girl. Inside Suman, his memories going into Allen's head and realized that Suman betrayed the Black Order to see his family. Desperately, Allen tried to reason with Suman as he travelled to a village in hopes of destroying it. Allen activated his Innocence to its maximum, his left arm stopped activating and broke, causing him to have intense pain. After saving Suman and his Innocence, Allen found out Suman's body is alive but his mind is dead.

Allen became devastated as Tyki Mikk destroys Suman body with his "Tease"s. After explaining his abilities to Allen, Tyki destroyed Allen's Innocence to see if it was the heart. Seeing that he supposedly didn't, Tyki had Tease eaten a piece of Allen's heart, making a hole and apparently killed him. However, before "dying", Allen had Timcampy take Suman's Innocence to Lenalee.

Surprisingly, Allen survived Tyki's attack because his Parasite Innocence's particles formed the hole in his heart and closed the wound. His Innocence wasn't destroyed but reduced into particles. Allen began training with the Black Order's Asian branch to restore his Innocence. During training, Allen found out that Bak is a stalker for Lenalee as he has numerous pictures of her. Allen and Fou began to engage in real battle training. Allen unable to reactivate his innocence, became frustrated and try harder as he desperately wants to return to his friends. Fou disguises herself as Lou Fa and talks with Allen, reminding him that he fights not for the sake of fighting, but for something precious to him. As he trains, a Level 3 Akuma attacks the Asian branch and as Fou was about to be killed by it, Allen revived his Innocence as "Crown Clown". With it, he defeated the Akuma and learned of the battle in Edo.

Allen then uses the Noah's Ark to reach Edo in time to save Lenalee from the Earl. With his new Anti-Akuma weapon, Allen easily defeats most of the Akuma. However, Kanda thought he was Tyki(who Kanda is fighting with) and tried to attack him.

Noah's Ark arc
As Allen caught up with the others, Lenalee and his emotional reunion is disrupted as Lero teleports Lenalee away. Allen, Lavi, Krory, and Kanda, are teleport together with her into the Noah's Ark. While searching inside, Tyki appears and gives him a key to Road's dimensional doors so he can escape the collapsing Ark. When his team used the key to open a door, Allen ran into Skin Boric. Kanda forced Allen to lead the others ahead.

The next door was opened. Allen found Jasdevi, in their split form. Allen, Lavi and Krory fight violently against Jasdevi but The Twins reveal that they were forced to pay a bill that Cross left for them that was worth 2 million yen. Allen decides to berate the twins as they want him to pay the bill by claiming that was nothing compared to what he has paid in the name of Cross before.

Feeling angry, the twins steal the key and force Allen's team to search for it amongst illusional keys. Allen gives Lavi time to find the key as he and Krory fight off Jasdevi. Allen becomes angry as Jasdevi attacks Lenalee and Chaoji so with Krory's Noah sensing abilities, they were able to stop the twins until Lavi found the key. With this, the twins merge into a single body, after being called kids. And Krory forces Allen to lead the others out of the Ark.

As Allen helps Lenalee up the stairs, suffering from Lavi's jokes, Allen reassures everyone will be fine. With this, Allen's team runs into Road and Tyki at the top of the tower and a fight later ensues between Allen and Tyki.

Allen and Tyki's battle reaches a point where Allen is able to hit the critical point(exceed 100%) of synchronizing with his Innocence resulting in Crowned Clown- Sword of Exorcism, which makes him capable of becoming a General. Allen unsheathes his new Sword of Exorcism and with it, he is able to exorcise the Noah from Tyki. With this, Road uses Lavi to attack Allen but Lavi is able to overcome Road and as they defeat her and she escapes, Allen tries to save Lero and Tyki. However, after Allen's failed attempt of exorcise the Noah inside him, Tyki is fully awaken as a Noah, turns into a demonic knight and easily beats both Allen and Lavi until General Cross arrives to rescue/ridicule them.

Cross orders Allen to control the Ark, and sends him and Timcampy into the secret room of The 14th Noah, where Allen faces a dark apparition in the mirror who calls Timcampy "My Timcampy. Timcampy projected a mysterious set of music scores, Allen begins to play on the white piano, at the same time thinking of his wish(give back friends), controlling and restoring the Ark. With the Ark, they take the Akuma Egg to the Black Order Headquarter.

Headquarters Invasion Arc
As a result of Allen having the powers of the Musician in order to control the Ark, he is able to save his friends. Controlling the Ark, thus stopping the download of Akuma's egg, so it does not funtion which causes a large amount of damage to the Earl's plans. Later, Allen ponders on how the symbols he and Mana created years ago were the song to move the Ark. Allen tried to confront his master about it, but he never gets a chance to. After Allen and his friend's return to headquarters, he is put under suspicion by Malcolm C. Levrier, who wants to put Allen on trial for treason. In order to ensure Allen's loyalties, Levrier has his subordinate, Howard Link to put Allen under 24-hour supervision. This causes many members of the Order to suspect Allen while close friends, including Komui, Lenalee, Lavi, Bak, Reever, and Johnny, believe that Allen wouldn't betray them.

The Noah, Lulu Bell brought her army of akuma and Skulls attack the Headquarters' Lab 5, where the akuma "Egg" is being studied. The army injures the entire science department and intending to turn the smart ones into Skulls. Allen and Bookman arrive through the Ark, struggle with the endless army of level 3 akuma. Lulubell has already secured the akuma "Egg" and opened a gate to the Millennium Earl. Allen was knocked out and kidnapped but was rescued by the Generals, taking back the Egg. The Egg was destroyed when Lulu Bell attempted to take back the Egg again. The victory is short lived as a level 4 akuma appears and easily pummels Allen and destroys part of HQ to the point where it drilled straight to the mantle of the earth itself. When Allen saw the Level 4's soul he started to vomit and stated it was too grotesque to look at. Lenalee with her new form of Dark Boots together with Allen overpowered the akuma. Eventually, the generals joined in and pour their full power in their attacks, and defeated the level 4.

Allen recently received word that he is to become the 14th Noah after receiving the memories of the Noah from the original 14th who was the brother of his adoptive father, Mana Walker. This also came with the grim news that he would someday lose his very soul for the 14th to be reborn in his body and that he was doomed to kill the "ningen" or " human(s)" he loved when that happened. Allen is probably very worried, but he has recovered a cheerful front and is trying to keep his mind on his duties. He later appears at the Black Order headquarters in North America preparing to battle the Earl and prevent him from killing the personnel.

Timothy Arc
He is on a mission now with Kanda and Marie to investigate a strange rash of thefts that has lead him to a boy named Timothy whose Innocence can allow him to control other people's bodies. Currently, he is engaged in battle with a second Level 4 Akuma and three other Akuma who are attempting to take the boy.

In chapter 182, the fight with the Level 4 was still ongoing, but it was going for the better. As Kanda managed to injure the Level 4, Allen lost his sword, when the Akuma grabbed it and threw it away. After running from the attacks, he managed to use his powers to call Crown Clown back to him, making it fly straight through the Akuma and through himself, pinning them to the wall. As the Akuma comments on him skewering himself and Allen explains the effect of the Sword of Exorcism, he is suddenly racked by great pains, as the Sword seems to be affecting himself as well. As the Akuma prepares to fire on him, the 14th Noah inside him surfaces. He touches the Akuma's cheek, causing it to stop, saying only "Good Morning". As the Level 4 is about to answer to Allen as Noah, it is skewered by Kanda before the Level 4 could pronounce the "h". Allen, who seemed under the 14th's control, looks at Kanda with a hostile expression. Kanda then provokes Allen by calling him "Idiot Bean Sprout". Allen's conscious immediately surfaces and the two slice the Level 4 to pieces.

Upon his return to Headquarters, Allen has a dream in which he is impaled on the Sword of Exorcism and a voice is telling him he is not without sin and that it is he who is in need of salvation. Mana appears in the dream and invites Allen to come with him - though he never calls Allen by name. He uses another name that Allen can't quite make out, symbolized by ***, three unknown characters. Allen asks Mana to call him by his name and then wakes up. His hair turns wavy and bares a hostile expression. This startles Lenalee, who has fallen asleep on the bed next to that of Allen's. Allen seemed not himself -highly likely he was under the 14th control- until Lenalee calls his name. Before the two could start a conversation though, they are interrupted by Link who has been unable to perform his duties because of Lenalee's "immodest state". Allen tries to lock him out for a moment, while Lenalee asks him whether or not he is feeling alright. Link threatens to tell Komui that Allen is alone in a sealed room with Lenalee. Allen immediately relents and opens the door. Later, Lenalee is shown thinking that Allen looked like a different person when he woke up.

Mystery of Kanda arc
In Jordan, Allen and a few Third Exorcists began fighting an army of Akuma. There, Allen sees what happens to Akuma souls when Third Exorcists absorb them, and his eye bleeds from it. After that, Tyki appears with some other Noah and began to attack, while taking shelter in a cave, Allen learns the fate of any Third Exorcist but Tyki reappears to battle them.

Allen manages to defeat all the Akuma and disappears and reappears to where the Noahs are keeping the order hostage. Allen comes from an ark gate beneath a black coffin ready to attack the Noahs but the Earl is waiting for him. As they meet, Allen and Tyki both manage to land on the Earl without seeing him. The Earl grabs Allen and tells him that he'll never go back to the Order, as he'll be leaving it by choice soon. As the Earl questions how he called him by saying "Good Morning" the Level 4 Akuma in the Timothy arc, Allen denies trying to contact the Earl. The 14th, however, appears, and makes a death threat, saying that he'll take over the Earl's place. During this, Allen goes through great pain, as if he were about to transform into the Noah.

After managing to recover, Allen informs the Noah, the Earl, and the 14th, he is Allen the Exorcist and nothing will change that. Wisely then hints at Alma's existence to Allen, and after Alma is brought out, he draws Allen and Road into Kanda's memories. He sees the younger Alma, who says "Raise your hand if you understand me." and does so, only to be stomped across. He realizes that Alma doesn't appear to notice him, and sees a hand rising from a circle of water. That hand then turns out to belong to a naked boy that gets pulled out by Alma. As he's finally pulled out Allen realizes that the child is Kanda. After that Allen watches Kanda's memories as he was involved in the "Second Exorcist Project". The Second Exorcists seem to be killed exorcists whose brains were transferred to artificial bodies. The scientists tried to transfer Innocence to those artificial bodies. Allen witnesses those painful memories and is almost consumed by Kanda's emotions, until Road explains to him that he's seeing Kanda's memories. In those memories Allen learns about the relationship of Alma and Kanda who were both part of the painful experiments and cruel researches of the Asian Branch and always fighting (and after that always regenerating and healing their wounds due to their modified bodies). Allen also witnesses Alma as he was eavesdropping on the scientists who intended to kill Kanda, because he seemed to have dreams of his real memories as an exorcist, and then tried to save his only friend and almost got killed by the CROW in the process. In the end Kanda thinks Alma is dead and survived himself.

After watching Kanda strike Alma down and having endured Kanda's memories long enough, Allen blows his top and punches Kanda in the forehead with his Crown Clown for allowing Wisely to "spy on his memories" for so long and forgetting his quick temper. Road notes that it's cruel of Allen to strike someone in the head with Innocence but he's also too late. Johnny and Bak begin to call to Allen telling him to stop Alma Karma before he wakes up and turns into an Akuma. Allen stares shocked at the demonic coccoon containing Alma but before he can react, the Earl tells Alma to "kill them" and Alma's awakening causes a huge explosion that blows up the entire North American Branch.

Allen survives, noticing Kanda is confronting Alma, but is shocked that Tokusa used his seals to protect him from most of the blast, despite his injuries. Allen begins to feel guilty that he couldn't save anyone at the time, a thought to which Tokusa knees him on the head, saying that being an Exorcist does not mean he can save everyone. Allen is then relieved that everyone is probably safe when Johnny contacts him. As Alma begins to turn into an Akuma, Allen witnesses Tokusa mutating. Allen attempts to help Tokusa, but is blown away into a wall. Then Allen's Crown Clown activates by itself and forces Allen to use Edge End on Tokusa. Allen begs for the Innocence stop threatening to kill himself with it if the Innocence didn't obey him, but Tokusa approaches Allen. Allen then watches Kanda fight Alma, and asks why Kanda is fighting so seriously to use Four Illusion Style. Tokusa then sneaks up behind him and attacks him, while claiming that he is not an enemy of Exorcists to stop himself, but is struggling. Then the Millennium Earl requests Allen to come along with the Noah Family as the Fourteenth if he wants the Earl to "put an end to this little show."

Cross
Allen's Anti-Akuma weapon, initially lacking an official designation but referred to as Cross (十字架（クロス）, Kurosu), 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. The name is sometimes incorrectly translated as Cross of God (十字架, Jūjika), a more literal translation of the kanji used.

Cross α (alpha): 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 scapula-joint. At this phase, his Innocence is capable of manipulating its size and shape even to extreme ends, such as when it grew enough to grab the entire body of the mountan-sized fallen one, Suman Dark.
 * 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 Lvl 1 Akuma simultaneously.

Cross β (beta): The next evolution of his Innocence occurred during Allen's investigation of "The Ghost of Matel". 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.


 * 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 of the palings. This ability is occaisionally mistranslated 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.

Crowned Clown
Allen's synchronization ratio reached a maximum of 83% before having his Innocence destroyed by Tyki. Yet unknown 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 true, fully-invoked form. When not activated, his arm is black and meets with his shoulder in a spiraling pattern that ends with tattoo-like emblem. Following this, the Order gave it the official designation of Crowned Clown (神ノ道化（クラウン・クラウン）, Kuraun Kuraun), due to its jester-like appearance when invoked. The kanji used in the name literally translates to God's Clown (神ノ道化, Kami no Douke).

When invoked, Crowned Clown acts as a body-armored Innocence, forming a white-hooded cowl and sleeve of Innocence energy which covers his shoulders and right arm, while his left arm and hand become slender and black, clad in armor and razor sharp claws. A masquerade-style mask is always affixed to the cowl, which takes on various configurations and appearances. This transformation also changes Allen's usual hairstyle from flat to a spiky rear. As before, his Innocence possesses a certain degree of sentience, but as Crowned Crown is able to manipulate Allen's entire body like a marionette when incapacitated, or simply assisting in evasive tactics.


 * Cross Grave (十字架ノ墓（クロス・グレイヴ）, Kurosu Gureibu): Much more powerful than its previous incarnation, Allen can crucify targets simply by etching a cross upon them with his left hand, effectively annihilating even LV3 Akuma with a single talon. It can now also be used defensively, generating a shield by drawing a cross on the air.


 * Crown 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 ribbons of energy 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 by himself.


 * Crown Edge (爪ノ王輪（クラウン・エッジ）, Kuraun Ejji): 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 Excorsism
The Sword of Exorsism (a.k.a Sword of Salvation) (退魔の剣, Taima no Ken):When Allen's synchronization ratio exceeds 100%, he is able to transmute his entire left arm into an exquisite broadsword with a large cross emblazoned on the face of the blade. In doing so, his left shoulder is capped with a cross-shaped emblem, and his cowl usually forms a cloak to cover the missing arm. Once invoked, the blade can exorcise evil from any vessel it strikes without any harm coming to the vessel itself if Allen chooses. If used against LV1 to LV3 Akuma, it vanquishes them in the same effect as the Cross Grave attack, leaving a residual glowing cross crest in the wake of the defeated Akuma. However, in the case of a LV4 Akuma the sword carries a diminished effect. Allen is shown with the ability to telepathically recall the Sword to himself, should it be separated from his body.


 * Death Ball (いちた たま, Sendo no Mari) When using the Sword of Exorcism, Allen can create explosion which he names, Death Ball.


 * Energy Arc When using the Sword of Exorcism, Allen can release an arc of energy at his target.

The Cursed Pentacle Eye
In addition to his Innocence, the reverse pentacle that scars his left eye curses Allen with the power to see the souls trapped inside Akuma. He received it after Mana died. The Earl appeared to Allen, offering to revive Mana for him. When Mana came back as an Akuma, he was angry at Allen and scratched him on the left eye, after which Allen's Innocence activated and exorcised Mana. Allen refers to his eye as "Mana" when it heals, evolves and a spirit is seen entering his eye. He comments, saying that it's "just like an Akuma" in the way that it evolves. The Earl has noticed Allen's eye and has made changes to stop the eye's power.

Pentacle Eye: The first incarnation of the curse is a black and red ringed eye which is automatically activated whenever Allen is near Akuma. It allows him the power to see the souls trapped inside Akuma. When Allen witnessed the self-destruction (under Road's orders) of the Level 2 Akuma and the disintegration of the soul powering it, his cursed eye bled in pain.

Evolved Pentacle Eye: 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 meters away. But the most astounding change is that others close to Allen are able to see the lost souls trapped within Akuma as well. After witnessing Allen's 'world of black and white', Lavi comments that the way Allen sees the world 'is like hell on earth'. However, the cursed eye appears to lust for the destruction of Akuma, often causing pain to Allen in the middle of the night by self-activating, as though "it is a sin to be sleeping instead of destroying Akuma". The eye also seems to activate itself even when no Akuma are nearby as long as dark matter is being used, such as when Allen is caught in the Noah Tyki Mikk's vacuum.

The Musician
It is revealed that Allen is the host chosen for the 14th Noah's revival, and was implanted with his memories at some point in his childhood while living with Mana, the 14th's older brother. The memories of the 14th Noah are said to gradually eat away at him until, eventually, nothing will remain of Allens personality and he will be reborn as the 14th Noah. As a direct result, he has begun to see the shadowy silhouette of the 14th looming over his own reflection.

Included among these memories is the power of the Musician, which allowed Allen to enter the 14th Noah's room and assume control of the Ark by playing the white piano within. In doing so, he halted the download of the Akuma egg plant, reconstructed the destroyed Ark and returned those who had previously been lost in its collapse, ultimately claiming it to be used as a tool for the Black Order. This power also lets any wish he wants to be granted, explaining how Kanda, Krory, Lavi and Chaoji come back from a lost dimension--despite Cross saying they were dead.

Cross states that the 14th chose Allen as he was running away with Mana and did not want to let this chance slip by. He also states that he knew both the 14th and Mana, and that the 14th told Cross to take care of Mana and if he died, the 14th would one day return to him (Mana). Another thing he states is that, Mana sort of lost it after the 14th died, leaving Allen to believe he may have not loved him at all - but simply the memories of his brother. Cross also told Allen he would have to kill someone he loved when he became the 14th. Cross ends his meeting with Allen by telling him to listen to the 14th and that there is "another side to this war".

Despite the prediction of his fate, Allen has vows to keep fighting no matter what, that he will not simply give in to the 14th's personality. The Order allows him to continue his duties under scrutiny, but puts restrictions on his Musician abilities. In addition, he is closely shadowed by Howard Link of the Order's special operations unit, CROW who is investigating and reporting his every move.

However, in later chapters Earl reveals that Allen isn't the player or the host of the memories that the 14th left behind, but he is the 14th himself. It is revealed after 14th connected to Earl during Allen's fight with the Lv 4 Akuma during the Timothy Arc. It hasn't been revealed how the 14th is Allen, since it was disrupted by 14th reappearing and declaring that he will kill the Earl and take his title.

Trivia

 * Allen is technically capable of becoming a general due to hitting critical synchronisation with his innocence.
 * The Earl refers to Allen as a "White-faced Clown" when he first sees him as the Crowned Clown (he also indirectly compared himself to an Auguste clown). An Auguste clown is really not a clown, but usually some noble who tries to get something done but is always pranked by the white-faced clown, the star of the show. This reflects Allen's constant battle against the Earl.
 * It is known that Allen can get lost very easily as seen when he was in Mateel. Some people also constantly remind him to not get lost.
 * The main protagonist was originally planned to be female.
 * In the D.Gray-Man Popularity polls Allen placed 1st in the initial poll and 2nd in the subsequent poll losing out to Yu Kanda.
