I'll type out the quick stuff and very very quick descriptions for the long stuff. If you like her abilities and the like and accept her on that, I'll detail it. An hour isn't much time to type stuff up :P. Also I'll have a picture soonish, I'm making a 3d model of her as we speak.

Name: Light Void

Alias: Light

Height: 5"6

Age: 20

Gender: Female 

Appearance: Light is a slender/tone white skinned humanoid looking thing with short light blue hair and black/orange eyes. Her head is vaguely sphere shaped with no nose and very large eyes. Her ears look more like fins than ears. She wears a blue tank top, a blue dress, and silver bracers. Her hands have 4 long clawlike/featherlike fingers that could look like a weird wing from certain angles. Her dress is a three sectioned blue set with a white trim and black inside with two of the pieces going down to her feet from the back, and ending at around her navel leaving a gap in the front. In this gap is a triangle shaped piece that goes down to her kneecaps. Her legs end in points where the feet would be and are quite muscular.

Personality: Light is a strong carefree intelligent girl who values freedom above all else. She doesn't think highly of most situations, and will usually try to find something to amuse herself, which can lead to her sounding like an airhead, overly sarcastic, or blunt. She is observant of the world around her, and quickly adapts to new situations as they present themselves. She dislikes people who have weak wills or people who restrict the freedom of others, but is otherwise friendly to everyone.

History/Backstory: A creature of the Void, Light found herself on earth when some rogue summoners attempted to open a portal to the void in the hopes of gaining power or something. Of course the ritual didn't do what the summoners had expected, and the vortex they were opening to gain power sucked them all in, leaving Light behind when it closed. And unlike the misconception of a void creature wanting to devour everything in sight, she only seeks to balance the world, as a world out of balance often times does not fade naturally back into the void, and instead causes problems for itself, the spirits within it, and the worlds around it. And of course she would also restrict the freedom of others if she fell under the stereotype, something she is very much against. 

Using her mask to move undetected within the human populous, she noticed that there were humans with superhuman powers, and villains with these powers as well. And some of the heroes or villains, didn't even look human! It didn't take her very long to notice that there were far more villains than heroes, and that these villains were mostly boring 'i'mma destroy' or I'mma rob dis bank!' types while the heroes seemed to use teamwork and acted like friends, and decided to be a hero based on those facts.
"After all, I get to punch things in the face, and most of the time they're super ugly. Plus Heroes can be fun friends, as long as they aren't boyscouts."

Equipment: A human face shaped mask that makes her look human, instead of her actual form. In her human form she looks sort of like her actual form, except her dress is an actual dress, her proportions are more human-like, her eyes are white and orange instead of her natural black and orange, and her skin is a fair color instead of pure white. Of course this is all an illusion, but a very convincing one.

Powers/Abilities: 
[b]Super Strength[/b] - Standard Super Strength ability
[b]Regeneration[/b] - Light has extremely fast regeneration that allows her to regenerate at the cellualr level. She can regenerate any missing body part or attach dismembmered body parts, including her head. Of course she still feels the pain of getting hit, just that she heals it up very quickly. This also makes her immune to Asphyxiation, being set on fire, Poisons, diseases, and all that fun stuff.
[b]Kinetic Combat[/b] - As Light attacks, her attacks and movement speed get faster. Having to regenerate or not being in a fight for a short while will reduce this speed drastically.
[b]Fusion Punch[/b] - Light converts her speed into an extremely devastating and powerful punch. Hit or miss, after being used, her speed from Kinetic Combat is brought down to base levels.
[b]Atrophy[/b] - Light emits an aura of Atrophy due to her void home. This causes things she is in constant physical contact with to slowly degrade until they fade into the void. This effect isn't seen though unless Light has constant contact with it for weeks on end. Magic however will be affected much faster, and can be sucked into the void within a matter of up to an hour.
[b]Air Jump[/b] - Light can jump off the air, giving her a sort of psuedo-very-easy-to-shoot-down flight

Additional Info: Light loves to dance, and can be a slave to the rhythm sometimes. Her big fingers make it hard for her to operate most types of weapondry unless said weapon doesn't care if the user has monster hands or not.
