Teddie is a mysterious character living inside the TV world, but after Persona 4 he starts living in the real world together with the other Investigation Team members. 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 Yuu, 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.
