- Audio Mimicry
- Noise/Sonic/Sonokinetic Form/Mimicry/Physiology
- Sound Physiology
User is made up of or can transform their body completely into sound. Users' transformed form is anatomically identical to their normal form, aside of being made of sound, in which case it contains all to organs and is somewhat vulnerable to attacks. Alternately the user can transform into homogeneous matter, without any part of their form being more important than the other.
In effect, the user can act as a living sonic boom; by simply moving at a fast-enough speed, they can disorient opponents, shatter windows and more.

- A room or other container paneled in soundproof surfaces can be used to imprison a user of this ability (until/unless they can revert to human form).
- Certain abilities (like Sound Manipulation) and equipment/technology may be used to tune into the user's frequency, disrupt the user's abilities and harm the user.
- Sound Absorption can be used to physically absorb a user of this ability.
- If the user has no control over this ability, the following can happen:
- May shift into (or out of) this form against one's will.
- Body may exude a constant hum (or a constant chaotic mix of sounds).
- One may produce a sound lower or higher than desired.
- Form may be permanent.
- Body may constantly move at the speed of sound.
- (In worst cases) Body may disperse into ambient air.
- Though the user does not need to eat, drink or sleep in this form, sound requires a transmission medium of solid, liquid, gas or plasma to exist.
