Black Lightning

Black Lightning is an unique form of Lightning Release. As the name denotes, the lightning is black in color. The amplified lightning is potent enough to kill its target, frying the victim's nervous system when they are struck by it. Darui is its only living user, having been taught by the late Third Raikage. Both users have the kanji for tattooed on their shoulders, Darui on his left and the Raikage on his right.

Trivia

 * Ginkaku and Kinkaku recognized Darui's possession of this ability through his tattoo.
 * It is similar to Amaterasu in that it is the only other black-colored nature technique.
