One of the first characters you meet in Shadows of Valentia. The rest is a quote from the Fire Emblem Wiki.

"While Tobin possesses a stubborn, serious, and direct personality, he is rather dense, being plagued with social obliviousness, and is poor at reading other people's emotions. Being the eldest of his family, Tobin maintains an air of brotherly warmth, playfulness, and kindness which inevitably transfers to his friends, those of whom he is extremely supportive of."

Tobin's english voice is Robbie Daymond. https://youtu.be/4tr3F08iwv0?t=123
