Being a comic relief character, Teddie is seen flirting at the girls of the Investigation Team on numerous occasions, but fails every time. Other than that, he is bubbly and cute and is known to lighten the mood when investigating the case, much like Chie. He idolizes and respects Yu, to the point of calling him 'Sensei.' In the Japanese version, he has a verbal tick, adding "-kuma" after every sentence, while in the English version his speech is filled with dozens of bear puns, like saying "Bear-sona" while summoning his Persona. He seems to care a lot about Nanako and calls her "Nana-Chan," even when she's in a near-death state after being kidnapped by Taro Namatame. In the beginning of Persona 4 The Animation, he acts much like a coward when Shadows are near, but changes his ways as the story progresses.
His biggest insecurity is his own identity. Throughout the story, similar to Rise Kujikawa, Teddie struggles to find out his own self and his place in both the TV world and the real world, as he has lost his own memories. As the story progress, Teddie begins to develop a fear that he perhaps has no "true self" and that he has no memories to recover, but continues to search for them regardless. After the "death" of Nanako Dojima, realizing that he couldn't keep his promise to play with her, and with his memories returned, Teddie griefs over the fact that he was an ordinary shadow who grew human emotions and wanted to be accepted by others. By the end of the game, following Nanako's recovery, Teddie comes to accept his true self and realizes that if he is an unknown being, then the way he could change was unknown as well, and vows to protect the TV world while living with the Investigation Team in the real world.
