Tendō

The Tendo is one of the techniques granted by the Saishu Ketsugan, and, according to Tako, one of the most destructive ninjutsu in existence. The Tendō creates a small fireball several hundred feet above ground level, not unlike the one created milliseconds after a nuclear weapon detonates. The fireball is several hundred times hotter than the surface of the sun. As it expands, a massive shockwave is created, which produces heat so intense it can instantaneously turn anything in its immediate vicinity to piles of carbon. Further away from the epicenter, the heat is still intense enough to fuse roof tiles together, a testament to the sheer destructive power of the technique.
