Igor is a recurring important figure in the Persona series. His role is crucial in every Persona protagonist's journey.
Igor has the appearance of a bizarre old man with a long nose, pointed ears and bulging, bloodshot eyes. He wears a black suit with white gloves
Megami Ibunroku Persona
Igor is the mysterious proprietor of the Velvet Room. In Persona, Igor calls himself "a servant of Philemon". He is always found in The Velvet Room between consciousness and unconsciousness, alongside Nameless and Belladona. He uses a phone made of bone to call up Personas from the depths of the soul.
Igor remains mostly unchanged. He is still a servant of Philemon and he handles Persona summoning in much the same way. Nameless and Belladona return, only this time they are joined by the Demon Painter. Outside of Persona summoning and dismissal, Igor tends for a brief while to Ulala Serizawa following her bout of Joker insanity, warning her to be careful with her emotions lest the Joker power return.
Igor is no longer seen with the phone but he still handles Persona fusion through the use of cards. Additionally, Nameless, Belladona and the Demon Painter are absent; instead, Igor is accompanied by an assistant named Elizabeth. Only the protagonist can enter the Velvet Room, and he does so for the first time in a dream. None of the other Persona users can see the entrance to the Velvet Room. The protagonist signs a contract with Pharso and Igor at the start of the game agreeing to take responsibility for his actions. Philemon is never mentioned.
Igor gives a key to Aigis and allows her access to his and Elizabeth's services.
He displays a small amount of kindness towards Aigis, commenting that they are both similar beings, referencing his origins as a doll given life by Philemon.
A Certain Day of Summer
Igor decides to reward the protagonist by reviewing memories of past events. The first event is something that happened after the trip to Yakushima.
Igor is seen with a new assistant named Margaret. Igor has the same role in this game as in Persona 3 guiding the protagonist. In Persona 4: Golden, the two are also joined by Marie, who serves as an apprentice.
Persona Q: Shadow of the Labyrinth
Igor is mentioned by Elizabeth, who states he has left the Velvet Room on the day the protagonist enters. His disappearance results in the room being unstable, and has Theodore tasked with aiding his sister while he is away.
During a Stroll after entering Inaba Pride Exhibit Night 2, Elizabeth mentions that she feels like she's growing weaker by the moment while Igor is absent from the Velvet Room.
During the final dungeon of the game, it is revealed that the Igor the protagonist had been interacting with the entire story is actually an almighty being named Yaldabaoth.
Yaldabaoth imprisoned Igor in Mementos and took up the appearance of Igor to test humanity to see if they were worthy of being able to live their lives of their own volition or be ruled by a being of order. To further conceal his identity, he also split Lavenza into the twin wardens, causing both to lose memories of his masquerade.
After Yaldabaoth leaves to complete his plan, the real Igor reappears back in the Velvet Room and formally greets the protagonist for the first time. Despite the fact that the masses' cognition denies the Phantom Thieves' existence, Igor reveals that the Phantom Thieves were merely held in special cells within the Velvet Room.The protagonist talks to his fellow thieves and spur them back into action. The last thief, Morgana, is nowhere to be found, whereupon Igor reveals that Morgana is a special existence that he created as a last ditch effort to guide the protagonist through his journey before he is captured. Igor tasks the Phantom Thieves with one final heist, steal the heart of Yaldabaoth. Overseeing their final battle, Yaldabaoth ruefully admits that Igor was right about humanity before returning to his original form of the Holy Grail.
In the victory of their battle, Igor congratulates the protagonist for overcoming a perilous ordeal and calls him an exceptional guest before the Velvet Room vanishes having fulfilled its duty on the protagonist's journey.
While presenting himself as a mere servant of Philemon, Igor seems to be far more than this. He was originally a doll handmade by a mysterious person, who became alive thanks to a magic ritual. Because of that, Igor ponders upon the question of whether he is merely a doll or perhaps even human. Thus, he shows an interest in human beings. Further on, he creates assistants such as Margaret, Elizabeth, Theodore, and Lavenza, who pursue similar questions in life to assist him in the Velvet Room.
In every Persona game to date, Igor has played the role of Proprietor of the Velvet Room, a space which transcends both dream and reality. As the proprietor, Igor provides insight to the protagonists regarding their powers, emotional bonds, and possible dangers that await them in their journey. Igor also provides the vital services of Persona fusion, which allows the creation of vastly more powerful Personas from preexisting ones; and the use of the Persona Compendium, which allows previously created and/or acquired Personas to be recalled at a later time.
Despite his rather striking appearance, Igor bears a calm and courteous demeanor while speaking with the protagonists. Though the well-being of the protagonists is important to him, he reserves the disclosure of certain information for more "timely" points in the story. During conversations concerning the protagonists’ actions, Igor opts for rather cryptic comments that tend to foreshadow coming events and possibly the outcome of the story as a whole, regardless of whether or not those comments are at the time understood (which may be his intent). This suggests that Igor may have near-omniscience, though by his own admission, there are things that even he can't foresee.
He looks carefully and closes his eyelids, slowly as he starts to pout the pieces together for what those cards really mean of what lies ahead of him. "I get it now....it's starting to become clear right now. I know what I must do to surpass this."
"What kind of card is it, that is suppose to be something that I am reaching to?" He was now focusing on the Tarot card that had read on it. If it is something important for him to see what it is, than he really must know really hard. If his hunch is correct, it could mean the Death might have something to do with it.
