Flying Nimbus

The Flying Nimbus (known as Kinto'un in Japanese, meaning "Somersault Cloud") is a sentient, golden cloud that responds to its rider's commands, flying at high speeds without requiring any energy expenditure from its passenger. Goku received the Flying Nimbus from Master Roshi as a reward for saving the sea turtle Umigame, and it became his most trusted form of transportation throughout the original Dragon Ball series and into Dragon Ball Z.

The Nimbus has one fundamental requirement: only individuals with a pure heart can ride it. Anyone who harbors impure thoughts or intentions will fall straight through the cloud. This rule served as a recurring comedic element in the series. Master Roshi, despite owning the cloud, could not ride it himself due to his lecherous nature. Bulma and Krillin also failed the test. Young Chi-Chi, however, could ride the Nimbus during her childhood, reflecting her innocent nature at the time.

Speed and Durability

The Flying Nimbus is remarkably fast, able to outpace most vehicles and keep up with aircraft. However, it can be destroyed by sufficiently powerful attacks. Tambourine obliterated Goku's original Nimbus during the King Piccolo Saga, but Goku later received a replacement. In Dragon Ball Z, the Nimbus saw decreasing use as Goku and his allies learned to fly under their own power, but it remained useful for non-fighters and for Goku's sons Gohan and Goten during their younger years.

The Nimbus made sporadic appearances in Dragon Ball Super and had one final, poignant appearance in the closing scene of Dragon Ball GT's last episode, when Goku flew off on it alongside the Power Pole into the distance.
