A tailed beast uses its massive chakra reserve to turn anything from a roar or a wave into a powerful force of pressure and destruction. When Naruto was in control while using Kurama's power, he demonstrated powerful shockwaves by roaring or movement of his arms, capable of deflecting projectiles, as well as repelling ninjutsu. When enraged or when Kurama took control of his body, he has been shown to use explosions with powerful wave of his arms. The raw force behind Naruto once he enters Version 2 was powerful enough to force Pain's Shinra Tensei back at him.
When used by the Ten-Tails with a single shockwave, it can destroy mountains while tearing up the landscape for miles in its initial form, as well as use it to initiate its Tenpenchii in its mature form after it recovers from its emaciated state.
