Alright, here's my pick (draft):
Emily Galbrett, Age 34
Born into the same household of a police officer as her younger sister, Lucy, Emily had a good upbringing. She wasn't rich, but her parents were at least just and fair. When she turned thirteen, she became a magical girl - at the time she'd been obsessed with flowers/nature and seemed to be on her path to becoming a gardener of sorts, and this was reflected in her abilities - she was capable of promoting unnatural growth in plants (using them to bind enemies to the ground so her teammates could beat them up), and any flower she holds (even if it's a hair ornament type of thing) becomes real and can fire off sharp petals at any opponent. A mid-range fighter, she tended to tie the area between the supports and the brawlers together and keep the team as a cohesive whole. It wasn't long before Emily introduced Lucy to their group, and soon afterwards she gained powers.
After they defeated their opponent, Emily's life seemed to be going well, the girl having an incredible interest in biology and similar subjects. Three years later though (17), Emily banged one of the other magical girl's brothers in a school staircase - not only did it anger her friend, but it also resulted in her having a child (Mary) and being kicked out of the house soon afterwards. Her life decisions - especially regarding men - haven't improved since them, but now that her daughter is 16 and just starting in the world on her own and Emily just wants the best for her. She's moved up to managing a fast food joint, and although the pay isn't excellent it IS a salary. She reminisces back to her childhood and her companions, but would do ANYTHING to protect her daughter, who only is somewhat aware something odd is going on with her mother. It's for her own good.
Though no matter how much she reminences, she cringes at the old costume she used to wear.
EDIT: Alright, be sure to think about how each of the characters relate to eachother, and keep thinking of the team name.
OOC should be going up later this week.
