Tengai Shinsei

Madara Uchiha weaves three hand seals simultaneously, by doing so in conjunction 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 collides with the first like an enormous hammer, breaking both apart and ensuring that they crash into their intended destination. Nagato can use this technique too. But his meteorite is smaller and he doesn't need any hand seals.

The impact of this technique was of such enormity that it devastated a significant portion of Gaara's Fourth Division when used against them, with the resulting tremors being so great, they could be felt as far away as the Allied Shinobi Forces' HQ.
