One Piece Film Z: Nico Robin

Robin is a mysterious and serious person who appears quiet and reclusive, and the wisest in the Straw Hat's Crew. She was thought by those around her to be cold and mean, but it was proven that she is actually a kind person who always thinks before she acts. She often only speaks when something interesting or important has happened. She loves to study history, and the comfort and freedom to study and read. She is also quick to point out gross or realistically morbid facts, often creeping out Nami or Usopp. Robin is the wisest and most sensible member of the crew. She has a vast knowledge of the seas and the world, and usually keeps her head during surprising situations, allowing her to logically analyze the situation without losing her cool. This trait makes her different from the other Straw Hats, who often comically react melodramatically to unexpected happenings and hold irrational ideas and conclusions. Despite her attempts to keep herself distant, Robin has fallen for her new friends, and has taken the role of the distant den mother.
