Yeah my backstory for her has her father being a super-villain.
After I posted them I looked at them and figured I liked Siren the best too, so I started work on her, she's pretty much finished. I'll post'er up and see if anybody can find what I did wrong (There's always something):
She's currently 2 pts over, still a WIP.
