Black Lightning

Black Lightning is a unique and more powerful form of Lightning Release. As the name suggests, the lightning produced by this ability's techniques is black in colour. The ability to utilise black electricity was possessed by the Third Raikage, who passed it onto Darui.

Trivia

 * Both users have the stylised kanji for tattooed on their shoulders; Darui on his left and the Raikage on his right. This seems to be a distinctive trait, as 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-coloured nature.
