One Piece enjoys no shortage of iconic characters, but even among its crowded field, Trafalgar Law is a fan favorite. Alongside Monkey D. Luffy, Law is a member of the Worst Generation, and following the Raid on Onigashima, the pair each possess a bounty of three billion Berries. As a child, Law vigorously trained in martial arts under Lao G, an executive of the Donquixote Family, giving him exceptional hand-to-hand combat abilities. The former Warlord of the Sea's Haki is also exceptionally strong; however, he still primarily relies on his Devil Fruit abilities during battle. With this power, he became one of the Grand Line's most feared warriors.
