Meteor of Flaming Devastation

 (爛壊滅の隕星, Rankaimetsu no Insei) is Seigetsu Uchiha's most powerful technique.

Usage
After watching his father summon a meteorite in their battle, Seigetsu found a technique of that scale could be effective for a last resort. Through this mindset, Seigetsu created a technique that memicked Sannoto Senju's very own metal meteor. Before creating this meteor, Seigetsu must shout out or mumble a poem, which goes as follows; "Set flames to the sky.. Spread apart the clouds.. Come down and aide me, set this world ablaze." A large meteor, matching Madara's in size shadows the world. This meteor is composed of pure flames, as when it touches the ground or makes contact with the target, explodes in a burst of flames engulfing the foe. Seigetsu too could find himself swimming in this flames, though to negate this, he utilizes his Fire Release Chakra Mode to cover his body in flames as well.
