Uran

Uran is Astro's younger sister and a major recurring protagonist in the Astro Boy franchise. She was created by Professor Ochanomizu, based off Astro's own blueprints, and presented to Astro as a birthday gift, or New Year's gift, depending on which series. Uran often finds herself getting into trouble and causing trouble for Astro. She possesses a part of Astro's strength but none of his combat powers, and her most common power is the ability to talk with animals. Due to how closely she resembles her brother, Uran is very rarely a player in the Osamu Tezuka Star System, and mainly appears in the numerous Astro Boy series.
