Dark Chidori
From Naruto Fanon Wiki
Name: Flapping Chidori (羽撃く千鳥, Habataku Chidori; Viz "Ominous Chidori"; Literally meaning "Darkned One Thousand Birds") "Games" Chidori Lament
Type: A-rank, Offensive, Short range (0-5m)
Users: Sasuke Uchiha, Kisho Yasuo
Hand Signs: Ox, Rabbit, MonkeyBy using the power of the Cursed Seal of Heaven , Sasuke forces his use of a third Chidori, which appears stronger than its standard form. While Kakashi Hatake taught Sasuke that the Chidori is a blade that protects the bonds he made with his comrades, Sasuke warps it into a blade that severs them. The The Flapping chidori glows black and instead of giving off the sound of birds chirping it gives off the sound of people screaming, which the Chidori was known for, it gives off the sound of many birds taking flight. Sasuke first used this jutsu in his fight with Naruto in the Valley of the End and clashed Naruto's Demon Fox Rasengan with his Flapping Chidori. Now that Sasuke has lost his Cursed Seal of Heaven, it is presumable that he can no longer use this technique.
