Black Lightning

Black Lightning is a unique and more powerful form of Lightning Release. As the name suggests, the lightning is black in color. The ability to utilize the black electricity was once possessed by the Third Raikage, who eventually passed it onto only a single individual, Darui. 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.
