Wolfgang Amadeus Mozart! I am the one who kills you. Your reputation, your songs, your vestiges, I shall kill them all. Should you ever manifest in this world, this time for sure, I shall kill you with my own hands. O' man loved by God, Gottlieb.
~ Sallieri declaring his intent to kill his rival


Avenger is an Avenger-class Servant able to be summoned by Ritsuka Fujimaru in the Lostbelts of Fate/Grand Order.

His true name is Antonio Salieri, though he initially poses as "Amadeus Alter". In life, Antonio was a peer and friend of the illustrious composer Wolfgang Amadeus Mozart, and was also a respectable musician that took on many young musicians as his pupils in the world of music; few of whom that were among his teachings being Mozart's own protégé Süssmayr, Mozart's youngest son Wolfgang Mozart Jr., and the legendary musician Ludwig van Beethoven.

However, the last years of his life changed when rumors started to spread in 1820 that he had assassinated Mozart out of jealousy of the genius loved by God. Salieri furiously denied the many baseless rumors that he had committed the act of taking Mozart's life. But as these rumors seeped into the public perception to the point that they had become synonymous with the truth up to his death, his existence has been irrevocably mixed with them along with the "grey messenger" that supposedly ended Mozart's life, turning an innocent man into a monster even after he ascended to the Throne of Heroes.

Though he should still be comparable to even the weakest Servants of this range).

However, due to having his existence twisted into an innocent monster by the legends of his assassination of Mozart, and his fusion with the "grey messenger", Salieri's personality has become cracked, and will become berserk at the sight of Mozart.

Weaknesses: Cannot fight in Spirit Form. He is obsessed with killing Mozart. Is very weak outside of his Wailing Facade form and must don it in order to fight.

Notable Attacks/Techniques:

Noble Phantasms

Dio Santissimo Misericordia de mi: To The Great One Up In The Heavens, Please Take Pity On Me

I am Death!
The murderer of the one loved by God!
Dio Santissimo Misericordia de mi!

~ Sallieri using his Noble Phantasm

Dio Santissimo Misericordia de mi: To The Great One Up In The Heavens, Please Take Pity On Me: A special move that Salieri would never have been able to acquire during life. It’s a musical Noble Phantasm that he can only possess as the Avenger Salieri. It’s his crowning musical accomplishment that rivals the music of Mozart. By condensing and coagulating enormous amounts of killing intent into the piece while infusing it with magical energy, it becomes a ruinous composition that attacks the mind and body of the target.

Class Skills

Avenger: The signature class skill of Avengers, representing the existence of one who gathers the grudges and hate of others and takes it onto themselves. Avenger converts damage and malice turned on him into magical energy.

Oblivion Correction: An Avenger never forgets, attacking from beyond oblivion with greater strength than other Servants. Thus the power of their blows increases whenever they strike an opponent's weak points.

Self-Replenishment (Mana): A skill that allows Avenger to replenish his magical energy over time.

Personal Skills

Innocent Monster: An attribute possessed by Servants' whose true lives have been distorted by their monstrous reputations, deserved or not. While alive, Salieri did not kill anyone. However, as the legend of him assassinating Mozart spread throughout the world in his later years and after his passing, Antonio Salieri was turned into an Innocent Monster because of it. For him, he has been given a rank of EX as a result. By fusing with the originally separate skill, "Self Denial", it turned into a composite skill.

Wailing Facade: An ability that was acquired after mixing together with the "Grey Messenger", an existence akin to the Reaper, who often appears in records related to Mozart and was said to have commissioned the composition, Requiem in D minor. In combat, Salieri's body is automatically wrapped in the shell/armor of an anti-hero, operating as a fighting machine of slaughter.

Flames of Slashing and Burning: The hateful rumor of Mozart's assassination by the hands of Salieri that spread like wildfire. This skill strengthens Salieri by the same ill will, slander, false rumors, demagogy and repulsing whispering that created him and turned him into what he is. It instantly weakens the enemies' collective morale and also functions as a strong mental attack. Should the enemy not possess any means of magical defense against this, it is possible to cause them to commit suicide.
