Dark Release: Judgement Flame (冥遁 裁きの炎 Meiton: Sabaki no Hono) is a Dark Release technique that combines Fire Release and Dark Release properties. created by Shikyo Fushiawase, and later used by Keshin Uchiha. This technique is one of the strongest Dark Release techniques ever created.
To activate this technique, Shikyo covers his hands in purple fire and then tosses it; as soon as it lands, it will instantaneously begin to spread rapidly. Anything or anyone it touches will instantly be incinerated so bad that even ashes won't even remain. It appears to be the only Fire technique that's able to possibly over power the godlike fire techniques that Kōkūhyō Nara uses.
