Unknown Physiology: Jao is a being of hardened cosmic gas, lacking any sort if internal structure. She is not truly solid, and can be pushed through with enough force, or cut by sharp objects. If cut, her essence will leak, causing her size to shrink and allowing her to be trapped, requiring her to sleep to recover.
Being made of gas, Jao is naturally buoyant, floating just off the ground naturally. She does not walk, instead flying everywhere, and are capable of reaching 60 mph. She cannot submerge herself in water without bobbing to the surface, and any more than a light breeze can blow them away.
Jao's body is ever-changing, capable of taking any shape between 1' and 12' in size. These changes are purely cosmetic: no matter how Jao changes herself, she always has the same general look. Her voice is harmonious and sounds as if it is coming from multiple places at once. Her body also matches her mood: when happy, the stars on her body will shine brightly enough to light up a small room.
Jao's senses are significantly difference from that of a human. While she has excellent hearing, on the level of a predator, and night vision, she has no sense of taste, smell, or touch, except when in a dream world.
