Master and host of the Velvet Room in all games in the Persona series. Most recognizable for his creepy stare and outlandishly long nose.
In Persona 1 and Persona 2, he is a servant of Philemon. In subsequent games, he makes no reference to his master, and only the main protagonists can perceive him. In all games, he serves to aid the protagonists in managing their Personas and in the latter games sets the heroes on the road to developing their Social Links.
In Persona 5, Igor is imprisoned by Yaldabaoth, who disguises himself as Igor for the majority of the game.
