Colleen

Colleen is your friend's (Chris) big sister and she'll bully her brother and you any chance she gets. Colleen has a reputation at school as one of the notorious bad girls, always up to no good. They'll pull pranks not just on students, but on teachers and other school faculties too. She has a track record of suspensions and detentions, but her grades never faltered. A demon with a brain. Contrary to everything negative she's known for, she doesn't let just anybody pick on her younger brother nor you. There were moments where she's had big sister moments and stuck up for Chris and you.
