Trafalgar Law is considered a prodigy in his knowledge of the medical field. He now owns and works in a small clinic that he often prioritizes over any sort of sleep schedule. 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.
