Real Name: Akane Hayakawa
Real Occupation (if any): Chiropractor/Acupuncturist
Alias: Red Phoenix
Akane is an athletic young Japanese woman. She has long dark hair, either pinned up, or in a single long tail secured by a pin. She has lightly tanned skin, delicate facial features, and large, dark eyes. Many hours of physical training, not for strength, but for general athleticism have given her the build of a dancer. Her long legs (for her height; she stands at 5'5") have a sculpted appearance. Despite her athletic training, she still has a very feminine shape, with softly curving hips, and full, firm, breasts.
Akane was born in a remote village in Japan that somehow managed to remain untouched by modernity. The village housed a secret: a centuries old clan of ninja. Akane was born to the head of this clan, and a woman from the nearby village, a woman who was very much not his wife. Desiring to be near her without acknowledging her, the clan leader took Akane into the clan as a ninja recruit. However, women were not normally allowed to be trained; as such, the leader concealed her sex, later with Akane's help. The ruse continued for quite some time, as both of them were skilled at concealment and deception. Akane excelled at her training, quickly becoming the most skilled ninja for her year, and for several years on either side of her. Once she turned 16, however, puberty had struck far too hard. Rather than suffer inevitable expulsion, Akane fled one night, never to return.
By the age of 19, she had found her way to the United States, and had set herself up as a heroine in a city. She had her successes, but she also had her failures (see Red Phoenix vol. 1 and 2). After a year, she is forced to move to a new city, her secret identity too well-known to remain. She makes her way to coastal city...
Powers: Superbly skilled at hand to hand combat, near to peak human levels, specializing in striking. High endurance, agility, and pain threshold. Stealth skills. Knowledge of movie-style pressure points (think Kiss of the Dragon, not Fist of the North Star), and can hit them at a few meters distance with thrown needles.
Weakness: Except for the pressure points, has no superhuman capabilities at all. Overconfidence. Conditioned weakness to pleasure, especially on the breasts, sexual suggestion.
I hope this is ok. She doesn't have very many weaknesses, except for being mostly human. Which might be enough. If y'all don't think that's enough, I can tone down the pressure points stuff.
Of the villains that have been mentioned so far, I think she'd match well with Tyrant Rex (she's vulnerable to suggestion), and Arashikumo (ninja vs. ninja!). Let me know if you have any ideas, or if there's something I didn't cover!
EDIT: Oh, she'd also work well with Tenshinhan's character, for the same reason she'd work well with chaoslord29's character. Whoops, sorry I missed that first time around!
