Carbon Control

At will, the user is able to freely manipulate any source of carbon they come in contact with. For external sources, the user is able to remotely control the said carbon, levitating it and moving it around. Upon which the user can launch it as a barrage of speeding projectiles that even the Sharingan has difficulty following. He can also increase the size of his projectiles to strengthen their sheer force, able to plow even through an Iron Sand Wall.

Alternately, the user can utilise used fine-tuned control over the carbon in their very body and rearrange the molecular-bond between them. In doing this, the user's body will take on a dark reflective state akin to metal. In this state, the user's body becomes super dense, as hard as a diamond, granting them immense physical strength and becomes impervious to virtually any form of damage. This ability can be used on any isolated part of the body or their entire being.

Trivia

 * The nature of this technique's application on one's person is virtually identical to the innate ability of Greed from Fullmetal Alchemist.
