Alright... This is really cool!!! Anyways, Here is what my character would be like:
Name: Either Alita or Gali (whichever you like best)
Look: Since she is half human & half droid, her body would be completely of metal, and she must wear a tight leather body suit ( preferably black) with a hunter green over coat. And she will have long blue-black hair with horns sticking out of her head. And she has to be petite!!
Theme Music: I can't think of the music now, maybe " an ode to no one" from Smashing Pumpkins would be cool??
Weapon: Her weapon is basically her fighting style... the only thing is she has amnesia so little by little she remembers all of her attacks.
Classes: she basically has the same name through out her development
Background: Has no memory of her past life. All she has left behind is a locket with a picture of a boy named Hugo. ( which was her first love but was then killed in a freak accident) Her head was found by Link in a junk yard full of scrap metal. He took her to Ido, which builds all kinds of droids and other robots.
If I can come up with anything else, I'll let you know. As for now my brain is fried...
