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.' His speech is filled with dozens of bear puns, like saying "Bear-sona" while summoning his Persona. In the beginning 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 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.
