I had an extra character to submit as well. Can't decide if she should be a Lost or an antagonist. I went way over the top with this one, let me know if she's unacceptable.
Name: Mia Luxae
Age: 13
Gender: Female
Sexual Orientation: Straight
Hometown: ??? (She doesn't remember, but it's Slateport City.)
Description: Mia's appearance reflects her personality. Her appearance is sort of half and half, and each side fades into the other (it's not an abrupt split). The left side of her head has multicolored pastel hair, and a blue eye. The right side has black and red hair, and a red eye. She wears a tank top, with the left side being white and pristine, the other being black and slightly ragged. The tank top has a motif on the back that splits between sides, with the left half being a pink heart and the right half being a red skull. She wears a pair of shorts, where the left half is simply blue denim and the right side is black and torn denim. Finally, her left shoe is a white sneaker with pink laces, and her right shoe is a black combat boot. (Whew, that took me a while.)
Her physical appearance is rather simple. She has very pale skin, and stands at a height of 5'3.
Personality: You might have already guessed her personality by her appearance. On one hand, she's the bubbliest and sweetest girl alive. On the other hand, she's completely insane. She's nice and sweet most of the time, but never anger her or suffer the consequences. She's very unstable, and you never know when she's going to switch personalities. She loves sweet revenge, and will go to any lengths to get back at those who hurt her.
Pokemon:

Reason(s) for going to the Chamber of Emptiness: She originally came purely by accident.
Extra Info: I don't know what her item would have been yet, or what her special abilities would be.
