Pluto (プルートウ, Purūtō^?), known as Bruton in the English dubbed 1980 Astro Boy television series, is a fictional character created by Osamu Tezuka. He was introduced in The Greatest Robot in the World (地上最大のロボット, Chijō Saidai no Robotto^?) story arc of the Astro Boy manga. He then appeared in numerous appearances, such as the 1980s series and the 2003 series remake. He even appeared in his own manga. The robot is presumably named after Pluto, the god of the underworld.

With his giant horns, Pluto was created to be the world's most powerful robot. His master, a fallen and corrupt sultan named Chochi Chochi Ababa the Third, orders him to fight and destroy Earth's mightiest robots. This is so that he might become "king of the robot world".

Pluto does not show any joy or sadness (or really any emotion) when destroying his enemies, claiming to be only obeying his master. Because of this, he refuses to take part in any sort of activity that doesn't have anything to do with fighting, nor does he care about anything else, claiming to be a "fighting robot". However, he is shown to never shy away from a fight, even after knowing that defeat is inevitable (such as when he promises Astro to not forget him, after going on bravely to fight Bora). He is also shown to be loyal to his master.
