Black Lightning (黒稲妻 kuro inazuma) is an Extra Skill that originally belonged to Veldora. It was passed on to Rimuru when his Direwolf mimicry evolved to Tempest Star Wolf mimicry, as it is an Intrinsic Skill of the Tempest Star Wolf species.

Ranga later learned it when he evolved into a Tempest Star Wolf himself.


Black Lightning is described to be very powerful with extremely destructive capabilities and can completely vaporize an opponent unless they can resist it.
