Black Lightning

Black Lightning is a unique form of Lightning Release utilised by the Third Raikage, who passed it on to Darui alone. Not much is known about it but as the name suggests, the lightning produced by this ability's techniques is black in colour.

Trivia

 * Both users have the stylised kanji for tattooed on their shoulders; Darui on his left and the Third on his right. This seems to be a distinctive tradition, as Ginkaku and Kinkaku recognised Darui's possession of this ability through his tattoo.
 * Sasuke Uchiha demonstrated the ability to use something similar to this, once when he fought against Naruto at the Valley of the End and subsequently after receiving Hagoromo's power.
