Nico Robin (ニコ・ロビン, Niko Robin), otherwise known as "Devil Child", is a fictional character in the One Piece franchise created by Eiichiro Oda. The character made her first appearance in the 114th chapter of the series, which was first published in Japan in Shueisha's Weekly Shōnen Jump magazine on November 22, 1999.

In the series, Robin is introduced as an antagonist, but eventually becomes the seventh member of the Straw Hat Pirates crew and the sixth to join. Acting as the group's archaeologist and historian, Robin is a Devil Fruit user who possess the power of the Flower-Flower Fruit, allowing her to sprout replicas of her limbs, and later her entire body, from any surface. As the only survivor of the island of Ohara, Robin is the only known living person in the world of One Piece with the ability to read the ancient stones called Poneglyphs, something considered threatening by the World Government, which forbids the practice.

Robin has become extremely popular and a breakout character in anime and manga fandom. She has also appeared in several adaptations based on the manga, including the anime television series in which she is voiced by Yuriko Yamaguchi and Anzu Nagai as a child in the original Japanese language, as well as by Veronica Taylor and Stephanie Young and Jad Saxton as a child in the English versions. She has also become a popular subject of cosplay, causing a trend in Japan where women attempted to replicate her iconic costumes.

The character of Nico Robin was created by manga artist Eiichiro Oda, the author of the manga series One Piece, and she made her first appearance in its 114th chapter, titled "The Course", which was first published in Shueisha's Weekly Shōnen Jump magazine on November 22, 1999. As a fan of film director Quentin Tarantino, Oda stated that he used as a source of inspiration for Robin's design the character of Mia Wallace, played by Uma Thurman in Pulp Fiction (1994), one of Tarantino's most famous films. According to Oda, Robin has her birthday on February 6, and is 6.2 feet tall which is around 188 cm. When asked by a fan what the nationalities of the members of the Straw Hat Pirates would be if One Piece was set in the real world, Oda replied that Robin would be Russian. Robin was a later addition to the story and Robin and Franky are the only crew members who did not appear in the original concept art for the Straw Hats. However there was a male member who was a botanist, which may allude to Robin’s Devil Fruit power.

Nico Robin, a character from "One Piece," is of the Oharan race. She is the only survivor of the Ohara Island's destruction, known for its scholars. In the world of "One Piece," races can vary widely, and the Oharans were known for their knowledge and expertise in archaeology.

Robin ate the Flower-Flower Fruit, a Paramecia-type Devil Fruit that allows her to sprout duplicates of any of her body parts from any surface within range. The number of duplicates she can create appears to be unlimited, so long as they are within range. Usually, when she uses her powers, she crosses her arms and makes an "X" shape across her chest, though it's shown that she does not necessarily need to do so to use her abilities.

She can sprout her duplicate body parts from her own body, inanimate surfaces, and even from other people's bodies. She can even sprout duplicate body parts on top of other duplicate body parts. She maintains full control of her duplicated limbs and can perceive sights and sounds remotely through duplicate eyes and ears.

Robin can create entire clones of herself and even sprout gigantic-sized limbs.
