Robin
Nico Robin has a tall, slim figure and long black hair. In the manga, she is depicted as having brown eyes with wide pupils. In the anime, Robin has blue eyes (except for the 9th and 10th movies). Robin also has a small, straight nose. In the anime, Robin's skin tone is also darker than in the manga.
Robin is quite similar to her mother, except for her hair color and hairstyle as well as her skin tone. Robin is also described as having "extremely long limbs", which is a great advantage for her fighting abilities.
After 2 years: She dresses cooler than before, her skin is also noticeably whiter and her hair is slightly curly, not straight like before. She often wears orange glasses and dresses and tops that reveal her chest.
