Nico Robin

Out of all the members of the Straw Hat Pirates, Robin is the most serene and has rarely been seen to act comically. She approaches life and the world at large in a calm and collected manner and is overall one of the most emotionally stable members of the crew. She is kind, polite and treats Luffy with more respect than the most of the crew, even when he acts impulsively, to the point where she will smile and laugh at his antics rather than berate him. Together with Zoro, she is one of the members that support Luffy's decisions unconditionally.

When the crew is sailing, Robin is usually reading and investigating data from the places they visit. She is very wise and very patient in everything. Robin does not play a specific role in the ship, but she can foresee what can be found somewhere and that (in her own words), is of advantage to others. Luffy considers her a very intelligent member.
