About me: Nico Robin, also known as the devil child, is the archeologist of the Straw hat Pirates. Born into a family of archaeologists, Robin is the daughter of Nico Olvia and an unknown man. Robin ate the Hana Hana no Mi at a young age, giving her the power to reproduce her body parts (or her entire body) on any surface at will. As the sole survivor of the destroyed West Blue island Ohara, she is currently one of only two people in the world known to have the ability to read and decipher Poneglyphs, a skill which is considered forbidden and threatening to the World Government.
Robin's life on the run since the tender age of 8 has taught her the ways of survival and self-preservation and has earned herself notoriety for being able to evade inescapable situations. Even Admiral Aokiji commented that she could have escaped from CP9 had she felt like it (she only abided by their rules and conditions in order to keep them from unleashing the Buster Call upon her crewmates).
Robin ate the Hana Hana no Mi, a Paramecia-type Devil Fruit that allows her to sprout duplicates of any of her body parts from any surface within range. 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. 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.
By sprouting multiple arms from her opponents' bodies, she can use her power to disarm her opponents, as well as put them into painful submission holds and even snap their bones almost effortlessly. She can also use this application of her power to twist and flip her opponents. Her power is excellent for fighting a large number of enemies at once.
Robin is a brilliant strategist due to her genius intellect: she is extremely skilled in using cunning deception and trickery to gain a strategic advantage over enemies who are more powerful than herself. In Thriller Bark, she is able to exploit the zombies' complete obedience to their masters, tricking Hogback into giving orders to the two zombies with Zoro and Sanji's shadows into jumping off the Thriller Bark mansion, effectively luring them away from Hogback without using physical force.
Due to her having spent years escaping from Marines and World Government, Robin is also tactically cautious with a strong perception of danger.
