TMNT Ashley Michelle

So after watching TMNT the movie (2007) i decided to write a fanfic with a friend.
Name: Ashley Michello
Age:18
Gender:isn't that obvious
Height: five foot six inches
Weight: 125
Occupation: student/x-gang leader/trouble maker
Family: Mother-deceased, father-deseased. (relatives on both sides won't recognize that she's alive.

Past- She became a gang leader in middle school, and in the beginning of her freshman year her mother was murdered by...guess who, the SHREDDER. And in reaction she beat up teacher and was expelled and held back when she moved to Manhatten, NY. So that's why she's an 18 yr old Junior.
