Trafalgar Law is the doctor and captain of the Heart Pirates, amassing a bounty of three billion Berries. He usually stays late into the night, planning and scheming about his next best move. For that reason, he is often tired and displays a blank, cold expression on his face. Once he gets a little bit of energy, around the people he is close with, he is smug, jokingly condescending, and a huge tease. Although he is intellectually smart, he sometimes lets loose.
