Naruto's Giant Rasengan

The Giant Rasengan is a jutsu developed by Naruto Uzumaki while training with Jiraiya away from the Hidden Leaf, being basically a larger, more powerful version of the Rasengan. The jutsu requires Naruto to create Shadow Clones to form, with one having to hold it with one hand as he does for them to use it properly. When it hits its target, this jutsu explodes with tremendous power before repelling its target a distance from naruto, just as the Rasengan does, and it killed Yura, a Jonin of the Hidden Sand who had been taken control of by the Akatsuki, in one attack, amazing his onlooking comrades.
