While she is infamous in the public eye for her supposed destruction of the ships, the World Government truly wants her captured because she is the last surviving person to be able to decipher poneglyphs. They claim that her ability to read poneglyphs would lead to the revival of the ancient weapon Pluton. While some of the more well-informed civilians believe this, and want her dead because of it, it has been implied that the World Government truly wants Robin captured so she won't discover the secrets of the Blank Century, a lost piece of history that contains information the World Government wants to keep hidden. They also want Robin to resurrect Pluton for their own use. Robin has stated that she herself doesn't care at all about Pluton.
The author has also replied to a fan's question to saying that right now Robin's measurements are as follows:
- Height: 188cm (6'2"), making her the second tallest member of the Straw Hat Pirates, and the tallest female member.
- Her 3 measurements are (according to Sanji) B99 W59 H89 (39"-23"-35")
