Six-Tailed Fox Menacing Ball

While in his Six-Tailed Fox form, Naruto disperses a massive amount of his chakra and blood into the air. He then solidifies this chakra into a sphere in front of him, firing it away when ready. The attack was strong enough to destroy a huge section of the mostly destroyed Konoha, but it had no effect against Pain's Chibaku Tensei.

Trivia

 * Apparently the technique is actually called the "Menacing Ball" and it can be charged with different levels of power.
