Harbingers of Fatui

Number 2 in Fatui. He is one of the most terrifying, cruel, and brilliant antagonists. Dottore's real name is Zandik, meaning heretic. Even during his studies, Zandik came to the conclusion that the human body is imperfect. He claimed that by modifying organs and implanting Kaenri'ah technology into people, humanity could surpass the gods. His theories didn't remain on paper. Even in his youth, Zandik secretly conducted experiments on humans, including lethal injections and detailed studies of the body's deterioration. After he was suspected of involvement in the death of a fellow student and evidence of forbidden experiments was revealed, the Academy expelled him in disgrace, declaring him a madman and a monster. Dottore's major scientific breakthrough was the creation of segments—independent clones of himself, created based on different periods of his life. There were six of them (age 8, 18, 25, 35, 45, and 65). All existing segments were completely destroyed by Omega. This was Nahida's condition in exchange for transferring the God's Heart to Fatui Electro. Omega coldly erased his remaining incarnations, believing the God's Heart to be far more valuable to his research than his own past. Realizing that his physical body as Omega was doomed, he managed to connect his consciousness directly to the Irminsul world tree. Using the accumulated energy of the God's Heart Pyro, he accomplished what he had been striving for for years—set the Irminsul ablaze. In his final moments, while the Irminsul blazed, Dottore managed to hold a final dialogue with his longtime ally and sponsor, the banker Pantalone, where they said their farewells. After this, the Omega version of the Doctor finally perished in the fire.

• No. 0 of the Fatui. The most mysterious and monumental figure in the Fatui hierarchy. He is the founder of the organization, its de facto leader. The founder of the Fatui and their leader. A former court mage of the ancient nation of Kaenri'ah, he was unable to prevent a cataclysm. He personally recruited most of the Harbingers. When Celestia and the Archons destroyed Kaenri'ah, Pierrot survived, but was struck with the curse of immortality. His half-masked face is a direct consequence of this curse. The realization that he was unable to save his homeland gave rise to deep sorrow and a furious desire for revenge against the Celestial Order. He chose the name "Jester" for himself as a bitter irony. Since the laws of this world seem absurd to him, and humanity blindly obeys the gods, Pierrot decided to become the one who would laugh at this divine tragicomedy—a jester.

• Number 1 in Fatui. Officially recognized as the strongest being in Teyvat in terms of pure combat prowess. He despises dirty tricks, intrigue, and backstabbing. He values ​​strength, courage, and devotion to duty. He treats both his subordinates and strong opponents with respect. In Mondstadt and other regions, soldiers note that the Captain personally ensures the supplies of his troops, the safety of his people, and never abandons the wounded, making him a befitting general. After the final battle with the Abyss, Pyro Archon Mavuika intended to give her own life to heal and save Natlan. The Captain intervened and blocked this decision. In the usual human sense, his earthly journey was completed, and he found long-awaited peace after 500 years of suffering. In Natlan, he is revered as a hero, and his name is inscribed on the honorary memorial of those who fought the Abyss. His soul returned to the arteries of the earth.
