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. It was strong enough to destroy a huge section of the mostly destroyed Konoha, but had no effect against Chibaku Tensei.

Trivia

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