Vanishing Rasengan

This technique is a incomplete Lightning Release version of the Rasengan, that was created by Boruto Uzumaki, and named by Sasuke Uchiha.

Usage
After creating a small Rasengan, Boruto subconsciously adds Lightning Release to it, before throwing it. As it glides, the nature transformation abruptly kicks in, resulting in the technique disappearing from sight. This adds an element of surprise to the attack, as an opponent may lower their guard, assuming that the technique has dispersed, only to find themselves struck by the invisible attack.

The size of Boruto's Vanishing Rasengan has seen a significant increase after the Mujina Bandits Arc, where it was shown to be around the size of a regular Rasengan. With enough chakra added to it, the Rasengan can become giant.

Trivia

 * In the Boruto: Naruto the Movie novelisation, this technique was stated to use a subconscious application of Wind Release instead of Lightning Release.
 * Kakashi Hatake failed to combine the Rasengan with his lightning-nature, causing him to invent the Chidori instead.
 * In the anime, Naruto was able to throw a standard Rasengan, similar to the main function of this technique.
 * In various media, when Boruto uses this technique, he simply calls it "Rasengan".


 * In one instance, this technique was depicted as orange in colour, similarly to how the original Rasengan is sometimes depicted in the manga when used by Naruto.
