Abilities: Kwan is Fast, so Fast she can dodge machine gun fire because she can see them in flight (to her bullets seem to move at best 5 kph)
She does everything at high speed when she isn’t interacting with others
She moves well over the speed of sound. [color=fff200](you can have up to Mach 5 but no speed force or time travel)[/color][u]No worries here I never liked the Speed Force because it seemed so odd[/u]

but her clothing and hair seem more affected by inertia than the air which demonstrate she has some form of [color=f7941d]special field[/color] around her  [color=f7941d](this would not be a part of super speed powers)[/color][u]Here I was making reference to the idea that most Speedsters must have some minor kind of force field that allows them to breath at High speed as well as escape the effects of friction; it doesn't provide any special protection beyond that but might later[/u]

Weaknesses: [color=8dc73f]Kwan must constantly exercise or begin vibrating this is because she is constantly filling up with energy and if she lets up for a little bit she begins having trouble understanding people or being understood by them.[/color] But that’s not her only weakness for she also has trouble with the cold and must vibrate to keep warm which once more makes it difficult for her to understand or be understood by others; long term exposure is even more problematic causing her to eventually slow down to nearly normal.

[color=fff200]I am getting a picture in my head of a girl who can't go to sleep. If she can't sleep eventually she would die. She wouldn't be constantly filled with energy unless she ate huge amounts of food. (Make the "large amounts of food intake" her weakness) She could vibrate to keep warm obviously.[/color][u]Here I can make the change[/u]

Make these changes and she will be good to go!
