Shapeshifting

The power in which one can transform to alter his or her body to match that of another person, animal, or object.

Capability
The user’s DNA structure instantaneously rearrange to the person of choice. The act of shapeshifting is sometimes painful and requires at least a few seconds to complete.

When the user is rendered unconscious, they revert back to their original form.

Variations
Some may only possess the power of:

Metamorphosis Doppelganger Malleability
 * The power to transform oneself into something else while retaining biological significance. Can turn into a person, animal, or small scale object.
 * A very limited power in which the user can physically copy someone that is in his eyesight and that person voice, without gaining that person powers or anything similar. The transformation is only temporary while the user can see the one who he wants to copy. Trained users of this ability can transform into someone simple by thinking in that person, thought in this case the transformation may be hard to maintain, and with some failures. The user also can only transform into a someone that shares a similar body structure, thus a human with this ability can only turn into humanoid creatures.

See main article: Appearance Modification Elasticity
 * An advanced form of shapeshifting that offers complete control of one's entire body density to morph in a liquid-like fashion through amorphous, abstract forms while retaining enough tension to prevent oneself from dissolving.

See main article: Elasticity
 * Similar to Malleability in which a person's body operates akin to a rubberband, their bodies can stretch to varying, but quite lengthy distances. Invulnerability to electricity maybe granted as a side effect.
