Matter Absorption

Sometimes called "Inorganic Duplication", Matter Absorption is a term used to describe the ability of some characters to absorb extraneous mass and add it to an individual's overall volume. The direction and application of this ability vary however most characters seem to absorb certain kinds of matter into their person and use it's mass to increase their own (such as absorbing glass to become razor sharp).
Other characters will simply absorb the mass and either replace it or place the mass elsewhere as to 'eliminate it'. In some cases, an individual with this ability uses their body simply as a circuit by which to shunt matter from one destination to another.
