Item from Dragon Ball by Akira Toriyama
A magical golden cloud that carries the pure of heart — Goku's childhood mode of transportation and the franchise's most literal moral compass.
Given to Goku by Master Roshi (who couldn't ride it because of his impure thoughts). The Nimbus only supports those who are pure of heart — fall through it and your conscience is exposed. Goku rode it throughout his childhood and still occasionally uses it. The fact that Goku can ALWAYS ride it — even as an adult — says more about his character than any dialogue. Chi-Chi could ride it as a child but hasn't tested it since marrying Goku. Gohan and Goten can ride it.
A small, puffy golden-yellow cloud that hovers and flies at high speed. Roughly the size of a person sitting down. Leaves a golden trail as it flies. Soft and solid enough to sit on despite being a cloud. Responds to its rider's verbal commands.
Also known as: Flying Nimbus, Kinto'un, Nimbus Cloud
