Lightning Release: Skyfall

Lightning Release: Skyfall (雷遁・空陥, Raiton: Soraochi) is one of, if not the most poweful technique in the arsenal of Kuukoyo. It becomes usable after she transforms to her true Tailed Beast form. This power stems from Kuukoyo's unique weather manipulation ability, which activates at the moment she transforms and proceeds to gather large thunder clouds to the sky. When there is enough power gathered in the clouds, Kuukoyo can call it forth. It will reach down to the ground in a blink of an eye, making it impossible to dodge by means other than time-space ninjutsu. According to Kuukoyo, it can easily level a hidden village, and it was powerful enough to revert Riyan Uchiha's Susanoo back into its skeletal form.
