Chidori: Star Crusher

The user traps their opponent inside a Chibaku Tensei, using the gravitational core and the surrounding rubble. The meteor then begins falling from the sky, catching itself on fire in the process. Then, the user surrounds themselves in electricity and, with a Chidori in their hand, strikes the falling sphere, resulting in an electrical explosion that can be seen even in space.

Trivia

 * This is reminiscent to how Sasuke saved Konohagakure by destroying a meteor in The Last: Naruto the Movie.
