Rasengan: "Uzuhiko" is a unique Rasengan variant developed by Boruto Uzumaki that harnesses the user's own chakra along with what Boruto calls planetary chakra—energy generated by the centrifugal force that works alongside the planet’s rotation and orbit—to infuse the attack with theoretically unlimited power.

Overview

In order to prepare this technique the user must maintain contact with the ground, ensuring that they can directly take in planetary chakra through both feet. The power and effects of the attack on the target depend upon how much planetary chakra the user gathers, and are therefore proportional to the amount of time spent accumulating it.

As the user absorbs this planetary chakra it visibly coils around their limbs and torso, and can be passed into the bodies of others by simply touching them. This can result in mild disorientation for those affected, making it more difficult to effectively move and attack.

The jutsu at maximum output.

In order to complete the technique the user strikes the enemy with their palm, typically aiming for their chest or stomach, and forcibly infuses the planetary chakra into their body. At maximum output, "Uzuhiko" is capable of killing the target with a single blow, erupting into a swirling vortex of chakra that forcefully blows away and tears apart their body, effectively disintegrating them.

At lower output levels, it deals damage similar to a standard Rasengan, along with the planetary chakra rushing through the target's body continuously inflicting internal damage and leaving the enemy in a perpetual state of vertigo, destroying their sense of balance and diminishing their motor skills. As these effects persist semi-permanently, ending only if the user rescinds "Uzuhiko" or the planet itself stops spinning, it causes not only physical harm but immeasurable psychological damage, making it an effective tool for interrogation and coercion.

Trivia

• Boruto finds this technique as an ironic counter against the Ōtsutsuki clan and its followers, as it is essentially the planet fighting back against those trying to kill it.
• Boruto refers to the planetary energy used for Uzuhiko as a "planet's chakra", but this is not the same as the "natural energy" used by ninja when they enter Sage Mode.
