Lightning Release: Black Panther

This technique creates a black panther-like creature composed of electricity that seems to emanate from the user's body. It can be used to affect multiple targets at once by electrocuting them.

The ability to utilize the black electricity was possessed by the Third Raikage, and he passed it onto Darui.

Trivia

 * As with many of the techniques of Kumogakure ninja, this technique has an English name given kanji that somewhat match the pronunciation.
