Known as the "Surgeon of Death" Trafalgar Law is one of the pirates called "Rookies", those which reached the half of the Grand Line with an over the one hundred million reward. He has an uncanny ability to create energy circles around him, with which, making use of a sword, divided his enemies into many parts, without actually killing them. Law is famous for his bad manners, despite he treated Luffy with respect, and violence. Note that Law has earned his nickname, since he claims to be a surgeon, proved when he saved Luffy after the battle of Marineford, healing a severe wound maded by the Admiral Akainu.
