Tengai Shinsei

Madara Uchiha weaves three hand seals simultaneously with his Susanoo, in order to draw massive meteorites from the upper atmosphere down towards a specific location on the ground. As they descend in succession along the same trajectory, if one of these meteorites is stopped, another one collides with the first like an enormous hammer, breaking both apart and ensuring that they crash into their intended destination.

The impact of this technique was of such enormity that it devastated a significant portion of Gaara's Fourth Division with the resulting tremors being felt as far away as the Allied Shinobi Forces' HQ, and to completely destroy Madara's Susanoo, which was able to take on several powerful attacks without getting so much as a crack on it, and obliterate his body.

Trivia

 * This technique was never named in the manga when it was used, yet it was named in the video game franchise.
