Rasenkido

Kevin's first attempts to create the ultimate jutsu is truly quite dangerous.

Using the Shape Transformation of the Rasengan, Kevin applies Storm Release chakra to create a maelstrom of miniature energy bolts within the nucleus of the rasengan. These bolts rend with the same strength as the Storm Release: Laser Circus, but the technique detonates into a large sphere upon contact with a foe, thus increasing range and damage. Kevin was wise enough to understand that the technique would have major recoil, and thus learnt to throw the technique early into it's development. Due to the natural superiority of advanced natures in comparison to basic elements, the technique does approximately three times the damage of the Wind Release: Rasenshuriken. However, it has been shown many times in the past that even a slight flaw in the creation of this technique can cause a detonation at close range, (which he has only been able to survive in the past due to help from his comrades) so Kevin uses the technique rather sparingly. When the technique is generated, it looks very similar to the normal rasengan with the addition of two orbiting 'rings'- hence the name.
