Ryukidosengan

History
This technique was created by Corelion Lelouche Shikaru, son of Sophitia and Ratatosk and inherritor of Sophitia's Dragon Clan Bloodline, when he witnessed Naruto Uzumaki's Rasengan first hand during a battle between them when he was younger. Being hit by the attack forced him to believe that none of his own attacks could stand up to Naruto's and so, he began training to learn the Rasengan from stories and books since Jiraiya and Naruto were off on their own. He eventually succeeded, creating this form of the Rasengan which he named the Ryukidosengan. This technique combines the base form of the Rasengan and Corelion's own Dragon Release chakra which he inherrited from his mother to create an extremely devastating attack.

Aside from the sheer intimidation factor of the initial appearance, the Lightning aura and the pitch black chakra on top of the normal Rasengan, this attack is brutal and deadly. When the opponent is hit with the weaskest form of this attack, which is the one Corelion used against Naruto Uzumaki in their second battle, they will be sent flying at tremendous speeds as if it was a simple Rasengan. However, the attack only became more deadly as Core grew. He developed a way for the Lightning aura surrounding the body of the Ryukidosengan to compress once the opponent was struck. Once compressed, the lightning aura would then split into the struck body of the opponent, immobilizing them as the sheer force of the attack fought against they're paralyzed body. This causes the Ryukidosengan to force it's way deeper and deeper into the opponent and, once it has gone straight through the body, it explodes into a burst of sharp Dragon Release laced wind blades, similar to the Rasenshuriken, but disintigrating the opponent from the inside, right down to the last skin particle. This attack requires an immense amount of Chakra to perform and, thanks to Corelions Dragon Clan Chakra pools being the largest known to the Shinobi World, makes it extremely difficult for anyone outside his family to perform without severely damaging themselves. Even the Kage of Uzushiogakure is baffled as to how Core can maintain such a powerful attack at his low rank.

This attack has single-handily taken down opponents of much MUCH larger stature such as several of the Akatsuki members, New and Old, and several major Shinobi of the world. However, several people have indeed survived the onslaught of the Ryukidosengan at even it's maximum strength, which baffles Core but drove him to begin further improving the attack to make it stronger. Corelion is currently the only meember of his family who is able to use this attack, however he is teaching others like his sister Whiskma Uzumaki, on how to use it since she was born with the same Dragon Clan Bloodline.
