Teodor, also known by the nickname Teo, is a non-player character from Persona 3 Portable. He can be chosen by the player to serve as Igor's assistant in the Velvet Room if the female protagonist is chosen. Teo can be found when the player pursues the female protagonist path when the appropriate choice is made. Aside from his usual requests, Teo will also tell the protagonist when there is a person who is stranded in Tartarus within a set range of floors. He serves as one of the ultimate bosses for the female protagonist path, the other being Margaret. Some of his requests will require the female protagonist to take him to specific locations in the real world, considered dates. It is unknown whether or not this can be considered canon. Throughout his dates, he proves that he is very proud and modest, pretending to know everything there is to know about everything. He can determine the secret ingrediant in takoyaki just by the smell of it, and can tell the temperature of water just by feeling it. He is not as humorous as Elizabeth, and most of his humor stems from his seriousness about his knowledge. He repeatedly asks Igor to install crane games and escalators, et cetera, into the Velvet Room, but always fails. He is the younger brother of Elizabeth and Margaret.
