Angra Mainyu (Avenger)

, Class Name , is the Avenger-class Servant of the Einzbern Master‎‎ in the Third Holy Grail War. He is an abnormal Servant that is not part of the regular seven classes.

He is one of the Servants summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.
==Profile==
===Identity===
Originally believed to be the Persian god of darkness himself, in reality, he was no more than an ordinary villager. A human that was freed from the confines of Order by having his name expelled from the Avesta, The Universal Revelation of Inscribed Creation. One day, he was randomly chosen as the "source of all evil in the world" by his village and was tortured and sacrificed in the ensuing rituals. The villagers, who were suffering from various disasters, eventually came to need a scapegoat for blaming their troubles onto. This scapegoat would be designated to be a demon and be chosen to be the reason for all the calamities afflicting the village. Simultaneously, he would be chosen to be the source of all the world's evil and by his existence, the villagers would have to be good by nature.
So they continuously tortured him until he went insane. They captured him, beat him, carved every word that cursed mankind onto his body, forced every sin imaginable upon him, took out bits and pieces of him slowly, defiled his mind with absolute evil, and held him responsible for all of it in the world. They would not allow him to die until he succumbed to old age. He had a curse put on him as a result, one made of the great evil that he was to represent. He was shocked at first at the senselessness of it at all. Eventually he started wondering who it was he should hate. However, Avenger himself only felt anger and hatred towards the world and the people that mercilessly executed him. His forced sacrifice eased the confused minds of his people, which despite being unintentional, qualified him to become a Heroic Spirit.
He only despised mankind of his own accord during the first few years, but after that, the hate became a natural function for him rather than an emotion; hate was the state he was always in, so it was only natural for him to continue hating everything without any other reason. By that time, he forgave and tolerated humanity for whatever sins they may cause while hating them. The world is worth hating. The imbalances were evened out by his hatred, so the people could be absolved of all guilt and live freely. But that kind of "forgiveness" is also the same type that validates any good or evil that humans may perform.
Yet as the time passed by and he saw many rises and fall of generations, he realized that while he still hated humans for what they did, he still loved the world. Of course, the people that put him up there, his family, his loved ones, the people he hated, died long before he did. The village changed over the generations, expanding, declining; people reviled him, people feared him, people scorned him, and yet they revered him as the sign of their salvation. But he could do nothing but hate, since that was the only thing he could communicate to the world. In the end, he accepted his role for humanity, even if it meant to be the blame for their wrongdoings.
As he watched the world for millennia, his name, his body, and his soul eroded away, leaving only his raw emotion of hatred behind. This hatred still remains watching the human world and will do so until its very end.
A helpless sacrifice—an ordinary person without any special talent—that transformed into exactly what they wanted, that was determined to be and came to represent All the World's Evil. And thus, hated by everyone and losing his self, a hero was born.
===Background===
He was summoned in the Third Grail war by the Einzbern family. The only Avenger Class Servant summoned was during the Third Holy Grail War, and rather than a true Heroic Spirit, an Anti-Hero was summoned. The Angra Mainyu that was summoned was a nameless figure merely crowned with the name of the King of Daemons who bore the six billion curses of the world. Angra Mainyu was to be a living calamity that would be able to win the Holy Grail War by brute force, as opposed to if the Einzberns summoned a Servant of the Ruler Class. Replacing the Berserker class for the War, the class was a special container created only for him, but he was extremely weak instead of something capable of slaughtering all other Masters and Servants.
He was quickly killed in four days and was trapped in the wish-granting spiritual Holy Grail. The power of the Grail as a wish granter received the wishes that humanity had placed on Angra Mainyu and turned him into a real daemon who would be the source of All the World's Evil.
Angra Mainyu was to be born, with the Greater Grail as a uterus, as an embodiment of the Third Magic. His influence tainted the Grail system.
 Originally the Grail system can summon only "good" Heroic Spirits, however due to his corruption caused the fourth and fifth Wars to summon irregular spirits.
Avenger himself is "a Heroic Spirit born into existence according to people's wishes". Other Heroic Spirits are recognized as true heroes, but Avenger represents the belief that "heroes" are lies and fabrications. The enshrinement of humanity's selfish desires turned Avenger into a Heroic Spirit, creating a direct connection to the wish-granting function of the Holy Grail. The Greater Grail, "activated 3 times without granting anyone's wishes", turned into its present state as there was still a chance to grant somebody's wish. 
As a result, Avenger was born into this world in order to grant everybody's desire for an existence like "All the World's Evil (Angra Mainyu)".
 Despite having been a normal, powerless being prior, the wish engraved in his soul by those who desired him to represent all the evils in the world was granted. Thus, the purpose of the 4th War was simply to gather vast amounts of mana to grant the wish.

Avenger does not have a "true" appearance since he is nothingness itself. In his original state, he possesses no personality and no appearance. It is only by possessing others as his shell that he is able to acquire an appearance and a personality based on his host. As he begins to return to his original state of nothingness, he begins to lose his physical features and look like a shadow.
In Fate/Zero, he used the form of Irisviel von Einzbern to communicate with Kiritsugu Emiya. His scorching mud had dyed her elegant skirt black.
In Fate/hollow ataraxia, Avenger takes on the form of Shirou Emiya. As Avenger, his overall appearance is based on Shirou but with darker skin, black hair, and glyphs tattooed all over his body. His clothing consists of a tattered red waist cloth, a bandana of same color, and black bandages on his forearms and shins. Furthermore, Caren and Bazett use oil paints to paint Shirou as Avenger in the Bonus epilogue, they both claim that they look identical. According to character toys and Chibichuki, he wears a red fundoshi under his waist cloth.
===Personality===
Originally he was a good-natured young man before he was randomly chosen to be the "source" of his village's evil and tortured until death. His hatred for the world became his very nature but he forgave humanity and accepted it, both good and evil. As nothingness, he no longer has any personality unless he possesses a host body.
In hollow ataraxia, Avenger usually has a lazy and laid-back attitude, lacking any sense of justice. This is best shown when he decides to kill innocent people in order to attract the attention of a Master and their Servant (since he believed it was the easiest way). He is also known to be sarcastic, cynical and mercilessly mocking towards the people he interacts with.
====Relationships====
;Edmond Dantès
:"Since we're both Avengers, the jealousy can not be suppressed. With things like black flames sprouting from his hands and wearing a coat, it's not like I feel inexcusable as the Senpai who's pretty much stark naked or anything. Setting that aside, he's flying around in the air too much."
;Gorgon
:"I knew that big sis had that kind of character too. To be specific, I knew since 2005. Even so, what's this...didn't she become far more atrocious than I imagined? Won't that swallow you whole if you try to tease her?"
;Darius III
:"In terms of mythological background, I'm extremely familiar with him, but, it's just too bad. Since I'm a free nameless Heroic Spirit right now, I can not respond to that wish."
==Role==
===Fate/Zero===
Angra Mainyu, in his Grail-altered form as All the World's Evil, reacts to Kiritsugu Emiya's statement "For that, even if I am to carry 'all the evils of this world' – it won't matter. If that can save the world, then I'd gladly accept it." while he is arguing with Saber after the deaths of Lancer, Kayneth Archibald El-Melloi and Sola-Ui Nuada-Re Sophia-Ri. Hearing that it has been called by someone, it wishes to answer him as soon as possible. While waiting for the "birth canal", the Holy Grail, to open, it dreams of the cries that will dye the world crimson red.
After Irisviel von Einzbern's death, Avenger records her personality at the time that the soul and conscience of Irisviel merged with the Greater Grail in order to use it as a shell to communicate with Kiritsugu. Avenger, now as Irisviel, claims that the record is unmistakably genuine, as the last thing that she touched before her demise was All the World's Evil. It inherited Irisviel's last desire by personifying her wish to "remain this way."
During the final battle between Kiritsugu and Kirei Kotomine, the Grail gushes out black mud which engulfed both of them. Though both of them entered in a dream like state, the Grail recognizes Kiritsugu as the victor. Avenger uses Irisviel to confront Kiritsugu in his mind and asks his wish, however it comes with a heavy price. In his mind, he was forced to confront the fact that his methods who practiced in all his life will eventually lead to him becoming the ultimate enemy of all humanity, equal to Angra Mainyu itself - and, 'Irisviel' proclaimed, this path is correct.
Kiritsugu, now realizing that the Grail is corrupted, shoots down all his loved ones including the illusions of his wife and daughter. As he rejected and strangled 'Irisviel', Avenger placed a curse on him - to never be free of regret until his painful death.
Kirei, having went through the same experience, questioned Kiritsugu why he rejected the Grail; Kiritsugu's answer was that it sacrifices too many things for what it gives. Kirei says that he wanted it even so and Kiritsugu, admitting that he did not understand Kirei, shot him in the heart.
In Kirei's last moments, the Holy Grail appeared to him in his mind. Filled with hatred and envy for Kiritsugu, Kirei reached out and touched the cursed artifact. He prayed for an end to humanity before his death and his wish was granted in the form of fire. Meanwhile, Avenger's emergence was prevented by Kiritsugu, who commanded his servant, Saber, to destroy the Grail upon recognizing the evil presence emanating from it. However, she destroyed only the vessel and not the contents - the 'black mud' - which spilled out from its core onto the streets below and caused a fire that eventually destroyed a large part of Shinto. The black ichor managed to soak Kirei's lifeless body, resurrecting him with an artificial, black heart. Gilgamesh was covered and absorbed into the black mud that poured out when Saber destroyed the Grail's vessel.
In the original novel, there was a scene where Gilgamesh contacted Avenger inside of the black mud that came out of the Grail. Avenger reveals the ugliness and hatred of the world, but to his surprise Gilgamesh accepts this and acknowledges his role in carrying the burden of the world. Gilgamesh's strong ego helps him fight off Avenger's influence and the black mud ejects Gilgamesh.
Kirei wakes up and finds Gilgamesh near him. He seemed to have gained a flesh body from something that flowed to his body through the Master and Servant connection.
====Einzbern Consultation Room====
Avenger appears briefly in the Einzbern Consultation Room, a segment not part of the actual timeline of Fate/Zero. Zecchan somehow entered the Grail. The Shades that Avenger manifested were chasing after Zecchan, but were stopped by his void-like figure. Avenger would order the Shades to attack Zecchan, but Irisviel would appear and save her from the Shades by cutting them down with her Naginata.
Zecchan tried to escape with Irisviel, she encouraged Irisviel to leave the Holy Grail by telling her she believes her to be a champion of justice. While running away Zecchan encounters Avenger. His body turned out to be an exit and Irisviel finally understood that Zecchan is from a different time period.
===Fate/stay night===
===Fate/hollow ataraxia===
The physical vessel for the Grail was destroyed by Shirou Emiya and Saber, along with the contents to prevent the disaster to be brought by the presence of Avenger in form of "All World's Evils". However, the soul of Avenger had become a real daemon due to the wishes placed upon him being granted by the Greater Grail. Wanting to grant the wishes of mankind as per his own nature as a daemon, he was reborn and transformed into a Heroic Spirit capable of fulfilling desires through the power of the Grail. After finally being able to grant a wish though and his soul disconnected from the Greater Grail with the destruction of its physical vessel, Avenger was left to expire without accomplishing his role.
Having become a weak Grail with the destruction of its physical vessel and his soul seperated of Greater Grail in process, Avenger being only in his spiritual form began searching for someone whose wish he could grant in order to do what it was born to do. In the process, he found Bazett, who after being left to die for Kirei days ago, wished hard that she did not want to die. Therefore, they made a contract: Avenger, to continue to exist and accomplish its new role of granting a wish, and Bazett, to stay alive even in a vegetative state. To keep Bazett alive after entering into her soul and mind to fulfill her desire to continue to live, Avenger created a dream world in her mind using the memories of Fuyuki and his inhabitants that he obtained through Shirou when Kirei Kotomine tried to use his curse to tried destroy and kill him in his final fight. As a result, Bazett's body went into a coma.
However, 6 months after the 5th war in real world, Caren came to Fuyuki city, found and nursed the dying Bazett in mansion. Unlike before, when Avenger just had to keep her physical signs alive, now he had to keep both Bazett's now awake consciousness and body alive. In order to accomplish that, he created the four-day temporal loop.
To keep Bazett thinking that she was still participating in Holy Grail War, Avenger recreated the 5th Grail War. The problem, however, was that he never personally experienced the 5th war. He only knew of the 3rd war. So he just took the participants of the 5th war and used them to create the characters in the 3rd war to play the 5th war's events.
While he was Bazett's Servant Avenger by night, he took on the form of Shirou by day. As Shirou, he comes to care for other people, especially the mysterious Caren Hortensia. In this form, he has no idea of his own identity and thinks and acts like Shirou. He later explains that this is because Avenger himself is 0, and no matter how much you add 0 to 1, it is still 1.
The problem starts when (1) Shirou, in truth Avenger, realizes the temporal loop and tries to solve the anomaly, and (2) Avenger himself begins to keep "filling up" the Grail to see more and more new events. Since Shirou is someone who cannot let the wrong stay wrong, he had to fix the abnormal temporal loop. Also, even though he knew that by seeking new events he would complete the Grail thus ending the loop, which would ultimately mean his return to void, Avenger could not stop enjoying the happy daily life as Shirou.
Later Bazett realizes the false reality of the temporal loop, but refuses to finish it. She thinks that she would die once the loop is over, but she also knew that would permanently take Avenger to nothingness. In her hope to stay alive, and her wish to keep Avenger from his ultimate fate, she tries to continue the loop, even if it means going against Avenger himself. During one of last loops, Bazett uses a Command Spell to make Avenger 'become her left arm' in order to keep him from contacting Shirou directly.
With help from Caren, the only one whom Shirou has never met and thus Avenger reveals his true self, Shirou/Avenger finally realizes that he himself is the cause of all the problem, and decides to put the end to it. He finally reaches the Grail as the other Servants and Masters prevent the monsters (which are actually leftover parts of Avenger) from stopping him. In the end, Avenger frees Bazett from the loop and returns to the void. In the process, it is revealed that while the reproduced Holy Grail War itself was due to the wish of Bazett, the daily life that Shirou experienced was due to Avenger's own wish to live a normal life.
After Bazett awaken from her coma in the real world with the end of the world loop in his mind and obtaining an artificial arm to replace her missing one, both she and Caren speak of the arm as if it is still Avenger.
===Fate/Grand Order===
====Fate/Accel Zero Order====
After Ritsuka and Mash return to Chaldea with Irisviel following Black Iri,'s demise, EMIYA tells Angra Mainyu to come out. Angra Mainyu does so and asks EMIYA why he didn't warn the others about him since they only destroyed the container, and not him, the contents. EMIYA answers he didn't want to rely on others intervening from another world. He also finds it logical to deal with Angra Mainyu alone since the latter's curse solely belongs to this world. Angra Mainyu criticizes him for continuing to be a Hero of Justice even after death. EMIYA has no regrets for his chosen path, though, saying he and Angra Mainyu will save and curse the world, respectively. Angra Mainyu asks for EMIYA's name. EMIYA uncovers his face and says his name is Kiritsugu Emiya. He declares he'll save the world like always. Angra Mainyu responds that there isn't a world that can be saved by humans, and wonders how long EMIYA will try to disprove that. The two then begin their fight.Fate/Grand Order - Fate/Accel Zero Order, ACT-18: The Fallen Grail
However, Chaldea failed to destroy the Grail completely, resulting in Irisivel being split into four elemental versions. Angra Mainyu tried to calm them down, only for the quartet to attack him. Ritsuka and Mash find him on the ground, defeated upon returning to the Grail's chamber. A fight ensues, though, when Angra Mainyu gropes Mash. Afterward, he confesses he saw them destroy the Grail with EMIYA's help. He then blames them for why he was on the ground. Irisviel arrives and explains the situation. She and Angra Mainyu wish Ritsuka and Mash luck in defeating the Four Elemental Iri.Fate/Grand Order - Fate/Accel Zero Order, ACT-EX: Retrieving the Holy Grail
==== Christmas Event: Merry Christmas from the Underworld ====
Angra Mainyu guards the second gate, and he immediately demands a present from Altera when she and Ritsuka arrive. He calls himself Shadow Santa, but unlike regular Santa, his presents are all garbage. According to him, though, it doesn't matter who delivers the presents, and says the genuine worth of presents is secondary at best. However, he understands Ritsuka and Altera are in a hurry and that the gate won't open while he remains. So to move things along, he eggs Altera into a fight by saying he enjoys killing. Altera defeats Angra Mainyu, only for him to take two presents from her sack. he scolds him for his greed, but he says children waiting for Santa's presents are greedy. Santa himself is also greedy for delivering presents to those who don't even believe him. The gate then opens, and Angra Mainyu hints Quetzalcoatl is the next gatekeeper before ascending.
==== Interlude ====
=====Unlimited Raise/Dead=====
His Interlude reveals that Angra Mainyu contracted to Ritsuka "without [them] knowing or wanting me to" and is so rarely available that Ritsuka is only barely able to remember them. This is despite the Interlude requiring the player to reach Max Bond with Angra Mainyu to unlock, indicating just how extremely haughty he is.
===Fate/tiger colosseum Upper===
AvengerTCending.jpg|Avenger's Ending
MagicalCarenTCending.jpg|Magical Caren's Ending
In Irisviel's story, Archer and Avenger are seen in the Emiya residence. Irisviel (which is an Irisviel of a parallel world that was brought by accident by Avenger and Neco-Arc for letting the Zelretch chest that they took from the Tohsaka residence at the beginning of Irisviel's story stay open) identifies Avenger as someone she once knew. With Archer, Avenger and Shirou arguing, Magical Caren tells Irisviel that they are all Kiritsugu's sons. Irisviel, shocked with this revelation, decides to take action as a mother. She lectures them about how brothers should take care of each other. She greets Avenger and calls him Angra Mainyu. Avenger replies that "It's been a while", although they haven't met in his current state. Irisviel was surprised to see Angra Mainyu as her son in this world and she is glad to see Avenger finally happy. Avenger claims that his body is of a hopeless ordinary man, but he is grateful to him.
===Capsule Servant===
Avenger is encountered in Bazett's story in Rin's route. After Rin picks up Lancer, Avenger calls out to her for help. Rin was surprised when Avenger spoke. Avenger almost introduces himself as Angra Mainyu, and tells Rin that he is able to talk because he is a lucky one. Bazett appears and orders Avenger to return to her capsule. In actuality, she wants Avenger back because Avenger is her only friend, but instead she claims that lucky talking Servants are illegal. These Servants are designated to be sealed, and the Mage's Association dispatched her to recover that Servant. Avenger yells out to Bazett, calling her a liar and a terrible person who abuses her Capsule Servant. He says that Bazett makes him go shopping, clean, and take her phone calls. He also complains about Bazett constantly feeding him beef bowl for breakfast, lunch and dinner which drove him to the height of insanity. His complaints make Bazett appear to be a lonely woman whose only friend is a Servant. Bazett tries to prove she has friends by showing the contact list on her phone. However, Avenger points out the that those on the list are all business contacts and Bazett, angered by this, challenges Rin.
After Bazett's defeat, she reveals she doesn't have a single friend and Avenger is her only friend. Both Rin and Avenger feel guilty, and Rin asks Avenger to return to Bazett. Avenger agrees, saying that they both bullied Bazett a bit too hard and it leaves a bad aftertaste. Bazett asks Avenger to return as friends. Rin questions why Bazett wants Avenger so badly, Bazett replies that she would rather have Lancer because she keeps getting doubles of Avenger. Rin decides to give Lancer to Bazett, and to her surprise, Lancer is a lucky talking Servant. Lancer tries to convince Rin that she can't trade him away and they are compatible like a dream team, to no avail. Bazett was happy to trade Avenger for Lancer as she claims Avenger to be rude and super weak. As both Lancer and Avenger try to convince their Masters not to trade, Avenger remarks that he expected the story to be a heartwarming story.Capsule Servant - Rin Route translation by Wakame Paradise
===Chibichuki!===
Avenger is a school "prankster". Due to the similar appearance with Shirou, Taiga Fujimura mistakes him for Shirou and he ends up getting educational guidance lectures.
===Other appearances===

Avenger cp.png|Avenger eyecatcher in the Carnival Phantasm - EX season.
Avenger makes a brief cameo appearance in the last episode of Carnival Phantasm, he also appears in a glimpse in the EX season episode.
In the Fate/Apocrypha universe, the Einzbern during in the Third Holy Grail War had two options to pick their Servant. The first option was to alter the system of the Greater Grail itself and summon Angra Mainyu to a unique Avenger-class Servant. The second option was to abuse one of the systems installed in the Greater Grail by summoning Amakusa Shirou Tokisada as the ultimate Ruler-class Servant, meant to be an impartial authority whom regulated the progress of the War. They would then make use of the great privilege possessed by Ruler: its Command Spells for the other Servants. They were in conflict between choosing brawn or brains. After much contemplation, the Einzberns chose Ruler. One could say that they picked the safer option; perhaps their previous defeat had robbed them of their confidence in powers higher than they. Unlike Avenger, Ruler was the last servant to survive in the Third Holy Grail War and he survived for the next sixty years. Ruler wished for humanity salvation and wished the happiness of all mankind, for innate goodness to be found in the heart of all humanity and the annihilation of Angra Mainyu: All the Evils of the World.
In the Fate/EXTRA universe, Angra Mainyu/CCC is the anti-planetary Noble Phantasm of the demon-transformed Kiara Sessyoin. Her existence is similar to Avenger who had once been demonized and celebrated as a sacrifice to prove the evil of mankind.

Avenger Beast Form.png|Avenger during his fight with Saber
Avenger was a regular human worshipped as a Heroic Spirit in life and considered to be Angra Mainyu, but he became a "mere human" again after his death. Despite such religious faith being placed upon him, he did not gain any unique abilities as a Heroic Spirit other than becoming free from the laws of order due to having his name stricken from Avesta, but that quality is not enough to be able to truly label him a Heroic Spirit. He is considered to have been garbage during the Third Holy Grail War, completely powerless and without any Noble Phantasms. He is only able to become the Heroic Spirit others wished for upon entering the Holy Grail, fulfilling the wishes piled upon him and truly becoming All the World's Evils. Within the recreation of the Fifth Holy Grail War, he has changed somewhat from the Servant serving the Einzbern Master, displaying a Noble Phantasm and having some use to Bazett despite his weakness.Fate/hollow ataraxia - Heaven's Feel - 5/ Void He declares himself to be the weakest of all legends in the world, boasting that he is "number one" in that regard, says that his Servant skill is "nothing", and believes even Bazett outstrips him in fighting ability.
He wields and , a pair of reverse grip weapons fashioned in the shape of a mix between a beast's fangs and claws. They were likely worshipped as real daemon's fangs and used in rituals during the era they were made. Brutish weapons varying greatly in size and shape, they are similar in form to throwing daggers originally crafted by the or tribes of Africa. As often with short swords, they are meant to be used as to stop an opponent's blade rather than rend flesh; one is able to catch a blade, while the other is used to attack. As they are not Noble Phantasms, it is possible to break them in the case of Saber easily doing so using Mana Burst to smash both with one swing. When acting as Shirou and properly meeting Caren for the first time, he projects a large number of them due to his compatibility with them, using them with great efficiency and shooting them as spinning projectiles.Fate/hollow ataraxia - ConfrontationFate/hollow ataraxia - 10/11 - Temple - A night at KageyamaFate/hollow ataraxia - EMA 6
He cannot keep up with other Servants with his low-ranking abilities, and a fight of pure ability with one will only lead to his exhaustion before losing. While he says that his combat ability amounts to nothing, he still believes he can buy time against a Servant. He uses a fighting style that will not allow him to win, but not cause him to lose even while surrounded by enemies. Bazett believes the reason that he can fight defensively extremely well while retaining his composure is due to being "unkillable" from the four day loop.Fate/hollow ataraxia - Heaven's Feel - 2/ Heaven's Feels Backnight II
Upon becoming Angra Mainyu, he was instilled with an instinctual knowledge related to the "rules" in his role as All the World's Evils.Fate/hollow ataraxia - Heaven's Feel - 3/ Dialogue Mobiuslink Despite being the weakest of Heroic Spirits, he, as All the World's Evil, can defeat even the most powerful human being. He is the strongest at "dealing with humans", not in the least scared of even a fictitious "strongest ultra humanoid in all of human history who has powers that surpass a Heroic Spirit." While almost useless in battle against Servants, his "natural inclinations" make him the second or third in ability to kill humans en masse. While he would normally be number one in that regard, he says the dog and the spider are better at murdering than him. While having never met them or competed with them, his innate knowledge lets him know that he can keep up in quality but pales in comparison to the speed with which they are able to kill.
===Unlimited Raise Dead===
 is the four day loop caused by his abilities. He initially lets Bazett believe that it is his Noble Phantasm. She believes the reason for his lack of strength in battle is due it being a weakness for having a Noble Phantasm that alters and interferes with destiny. He tells her that it has no cost due to emptiness being his nature, allowing him to resurrect in the evening as long as there is nothingness.
With the death of Bazett or the end of the fourth night at midnight, the "abnormal returns to normal" as the curtains close on the battle. What should not have been possible returns to the void from which it came, obliterating the four days without a trace and erasing the past as the new day begins.Fate/hollow ataraxia - Final night
===Shade===
 is the form that the remains of Avenger take in the looped world of Fate/hollow ataraxia after he is defeated: a shadowy void that is barely shaped like a wolf-man.
Similar to daemons, though much weaker in power. Still strong enough to slaughter any normal human, while someone with 10 years-worth of martial arts training might be able to last a few seconds in a one-on-one fight. The real problem is that it appears in massive numbers, having been born from a spiritual disruption meant to "create the same kind of monster".
===Skills===
====Class Skills====
*Avenger (A Rank): Resentment and hatred are easy to accumulate.
*Oblivion Correction (A Rank): (One that attacks even when the other party already forgot about it.)
*Self-Replenishment (Mana) (E Rank): Mana continues to endlessly surge forth until vengeance is achieved.
====Personal Skills====
*Zarich (C Rank): A weapon bestowed with the name of an evil god. Receives the attack of the enemy before intertwining it.
*Tawrich (C Rank): A weapon bestowed with the name of an evil god. Destroys the entangled weapon of the enemy.
*The End of the Four Nights (EX Rank): 「The Boundary of the Looping World」 which announces the end. A powerful debuff is put on every enemy. The conditions of his own party are also returned to their default state. (Not implemented in FGO.)
*Annihilation Wish (A Rank): The action of an existence that doesn't balk at death. In combat, it works by ignoring the limits of the flesh and increasing the speed ad infinitum. Of course, what is at the end of that is a loss of self, but, a moment before burning out, for the last few seconds, Angra Mainyu is able to become a top-class Servant.
==Development==
===Creation and Conception===
Despite hollow ataraxia not having been completely worked out at the time of Fate/Zero's development period, Gen Urobuchi was able to get the mechanics behind Avenger's method of "possession" by chance.

Angra Mainyu was implemented in Fate/Grand Order on April 27, 2016, however this wasn't acknowledged in the official websitehttps://news.fate-go.jp/2016/krhyob/ nor the Servant release trajectory released in 2023.https://www.fate-go.jp/trajectory/servant/
