Yaldabaoth observes the protagonist's process, which he calls the protagonist's "rehabilitation" as the protagonist forms the Phantom Thieves and takes down the rulers of each Palace, steadily providing the protagonist with more services of the Velvet Room. Yaldabaoth disguises himself as Igor, claiming to be Igor himself, which he does for most of the game. The protagonist first meets Yaldabaoth when sleeping his first night in Tokyo. Yaldabaoth installed the Metaverse Navigator on the protagonist and Akechi's phones so they could navigate through Palaces. If he won, then humanity would be saved, but Yaldabaoth rigged the outcome by influencing the public's cognition into following his preferred outcome regardless of how much the protagonist was able to succeed, ensuring that he would rule no matter who ended up outsmarting the other. The second was the protagonist, who would become a Trickster and rise up against the corruption of society. Simply put, if Akechi won, then humanity would be met with ruin. This would ensure that Japan and then the world would be placed under brutal, authoritarian control of their own will, which Yaldabaoth would in turn rule over himself. The first was Goro Akechi, meant to incite panic and chaos within the public with Shido's conspiracy ordering mental shutdowns and psychotic breakdowns of their opponents so Shido could become prime minister. He put two people against each other in a game. Yaldabaoth then decided to conduct an experiment to decide if humanity should be ruled over by him or allowed to live without him. From there, he imprisoned Igor and split Igor's assistant, Lavenza, into two twin wardens known as Caroline and Justine, who were taught that humanity should be punished. Too prideful to allow himself to be proven wrong, Yaldabaoth absorbed the Velvet Room into Mementos, a large portion of another realm known as the Metaverse that is maintained by his presence and the public's cognition. Igor, the proprietor of the Velvet Room, disagreed, believing that humanity could be saved. Yaldabaoth saw the corruption of humanity through the deadly sins and decided that humanity should be met with ruin. The public's cognition turned Yaldabaoth into a god. Yaldabaoth was created as the Treasure of Mementos, a manifestation of humanity's wishes to be ruled over. He is voiced by Masane Tsukayama (who also voiced Zouken Matou) in the Japanese version, and by David Lodge in the English version. Whatever the outcome is, humanity would eventually fall under his control. He manipulated the Phantom Thieves of Hearts and Shido to make them go against each other, while he himself would either destroy the world (if the conspiracy ensued) or enslave humanity (if the Phantom Thieves won) dependent on the outcome. Residing in the center of Mementos while pretending to be Igor, Yaldabaoth is the one behind the Metaverse's origin, the conspiracy of Masayoshi Shido and his minions, as well as all the turns of events by granting the protagonist and Goro Akechi their Persona power. He is also the posthumous overarching antagonist of the third semester during Royal although unintentionally, as it was him who caused Takuto Maruki's persona, Azathoth, to not only awaken but also go berserk and control him after Yaldabaoth merged Mementos with reality. He is the manifestation of humanity's wish for order and control, considers himself to be a god, and represents all of the deadly sins. Yaldabaoth, also known as the God of Control, Holy Grail, Malevolent God, Prison Master, and Warden, is the overarching antagonist of Persona 5. ~ Yaldabaoth's villainous breakdown before getting shot by Satanael's Sinful Shell. Was the human world worthy of salvation? Or destruction and rebirth?.
