Rasengan

Template:Jutsu The **Rasengan** is a powerful A-rank technique created in Konohagakure by one of the previous Hokage. Having taken three years to properly develop the technique by observing the Tailed Beast Ball, the plan was to take the shape transformation of one's chakra to the "highest possible point" and then combine it with his chakra's nature affinity, creating a technique that did not need the aid of time-consuming hand seals to control. The Rasengan however, is incomplete. One could think of it like a blank slate, as to achieve it's full potential, it must be merged with the user's chakra nature, however, this is only in theory, as it seems to be impossible by even the standards of the some of the strongest ninja. But on shape transformation alone, the Rasengan is still a very useful, powerful, versatile, and difficult technique to learn and master.

Due to this, a 'complete' Rasengan has the most versatility out of almost any technique in forms of variations; it is able to accept any chakra nature, and multiple variations of even the standard Rasengan exist, from enhanced versions to rotating typhoons.

## Usage

   The Rasengan does not require any hand seals to use, relying only on the chakra control of the user. Once it is complete, it becomes self-sustaining, which does not give the Rasengan a definite limit. The compacted nature and moving speed of the chakra allows the Rasengan to grind into whatever it comes in contact with to inflict major damage. This tends to launch the target backward after being hit or, if the target is lying on the ground or being launched to the ground, the destructive force is enough to form a crater.

The Rasengan was designed to use the caster's elemental affinities, however, even it's creator found this a difficult task to do. Despite this, the Rasengan has many uses and is a flexible jutsu for creating several variations.

### Learning

Learning the Rasengan can be broken up into three steps:

* The first step was learning how to burst a water balloon by spinning the water inside in multiple directions at once using only the user's chakra, which emphasises rotation.
* The second step was for the user to burst a rubber ball, and since rubber is thicker, and air is completely different from water, it forces the user to use denser chakra to break it. This step emphasises power.
* The third and final step was to combine both step one and two by spinning chakra inside a balloon without moving the balloon itself, emphasising stability of the sphere shape.

Although users generally learn how to form the Rasengan with one hand, those with poor chakra control can use one or more shadow clones to help in the creation. By having the hands of the shadow clones act as shells, they can complete and use the technique without using any extra time to master their chakra control.

### Improvement

The Rasengan is a technique that can have several different variations, depending on size and chakra output, elemental natures, or even the type of chakra being used to form the sphere in the first place. As such, shinobi can have their entire arsenal consist of variations of this one powerful technique.

## Trivia

* In canon, the Rasengan was created by Minato Namikaze. For the purposes of alternate universe fanfiction, the Rasengan is now a technique teachable to any Konoha shinobi.
