The Bruin is a big kid - he's curious, adventurous and often finds himself with a ferocious hunger. That being said, few are happier or more mild natured than the Bruin when his belly is full. Although the Bruin gives off a blue collar vibe, he is one of the well-educated Guardians. This fact is attributable to the Boston area being home to over 100 institutions of higher learning including the oldest University in the United States. The Bruin is incredibly fast, has an uncanny sense of smell and is able to track things from miles away.
He is the resident early alarm system for the Guardians as he can literally smell trouble coming. He's an excellent interrogator because he can tell if someone is lying just by smelling them and he has a roar that can freeze his opponents with fear.
