ウラン

Astro's cybernetic sister in the manga and anime series Astro Boy, as well as its many adaptions. She is a superhuman android with a naive, tomboyish personality.

She is the third robot addition to Astro's family, the first two being his parents. Uran is an extremely mischievous little girl who constantly lands her older brother in trouble. While lacking Astro's weaponry and propulsion systems, she is extremely powerful.

Like Astro, she is fully capable of experiencing human emotions (although she is somewhat immature), by being naughty or disobedient, even annoying.

2003 Series:

Uran reappears in the 2003 series with the name Zoran, with a slightly altered look, including a more appropiate dress in order to appeal to more western audiences. She still retains her tomboyish personality and cheekiness, however is shown to be more adventurous (which instead often puts her in trouble). She is given the ability to communicate with animals and befriends a bird which she names Houdini, however is often jealous of her brother's powers (such as the ability to fly, as well as his popularity).
