Body Weight Alteration Technique

This ability's main strength is that it allows the user to change their weight at will. They can go from being 1 kilogram, light enough to float on the wind with an umbrella, to 10,000 kilograms, dropping with intense force to crush the opponents. Even with one's weight increased, it seems as though the user can move normally, instead of being weighted down by their own mass.

However, in the case where the user is dropping with extreme weight, a swift enough opponent can simply dodge the attack while the user crashes into the ground. Additionally, because of the user's incredible mass, they can do so almost fearlessly, sustaining minimal damage, as even when Kakashi dodges Bunchin's attack and he falls through the earth, he appears moments later only slightly scuffed up. It also seems that the change in mass is not instant, but gradual, since Bunchin was knocked away by Naruto and his clone before he could gain enough mass to crash down on Sasuke.

A user like Bunchin who created this after viewing the akamichi clan's secret technique can fight on the ground by delivering heavily weighted punches. His selection of Presses are even more powerful due to the speed gained by dropping on an opponent.
