Despite his tough childhood on the street, Bolin is still a laid-back, and fun-loving person, in contrast to his older brother Mako. He has a good sense of humor, but is still a very capable earthbender. He is also expressive, naive, high-spirited, enthusiastic, and quite comfortable in his own skin. According to Mako, he has a "knack" for getting himself into trouble. He is typically an optimist and enjoys the attention he gets from his fangirls, though he is a novice in the world of dating. Bolin says that he is strong, fun, and gorgeous.
