This is actually pretty awesome; #3 pays for having the best power set of a PC so far by being half
Psycho Bitch and half
Wide-Eyed Idealist. Given her creation story, though, it's hard to tell whether things went horribly wrong or horribly right (since he might've been
trying to create a weapon)
She probably infiltrated the research center for purposes of espionage or mayhem, since she wasn't born there (her creator's not on good terms with the authorities; they already tried offing him, which not only failed, but turned him ino a Mad Scientist). Perhaps her creator's still alive (despite the possibility of dying to the freak lab accident/getting killed by his own creation since she woke up in psycho mode)?
I can't wait to see more of the supervillain hunting trio, too, and how they interact with the new/main PC groups. On that note, didn't you say that you needed three new PCs for the new group?
#3 was never given an actual name due to circumstances, but is easy to identify due to her appearance and the large number
3 tattooed on her left shoulder.
