Bio-conversion

Body conversion is a super-power which refers to the ability of an individual to transform the atomic structure of their own body or the body of another into an alternate substance. This power is widely used in comic books of the superhero fantasy subgenre.

A classic exmaple of body conversion would be the Sandman - a supervillain featured in Spider-Man and Fantastic Four comic book titles by Marvel Comics as well as the 2007 feature film Spider-Man 3. The Sandman had the ability to transform his entire body into silicon particles, which he could manipulate to form a wide variety of shapes. He could also use this power to enlarge his own mass and project columns at sand at opponents or erect barricades of sand.
