Holy crap this is old by now
Meet FLY
She's a bit familiar, isn't she? Almost like... a fusion of Fi and Flick, right? Yeah, it's because she is! :D
Fly is an AU version of Flick who fused entirely with Fi, and permanently so. Like at least one other evil AU Flick, she was motivated out of loneliness, but also psychosis, believing delusions about people who didn't become her friend (everyone). In reality, this was because she kind of snuffed out their lives...
In the MU (main universe), Flick befriends Neko, which sets her on the path to being good. THIS Flick DIDN'T go down that path, and became worse. She blames Neko for this, and sought out hundreds of other universe's Flicks and Nekos to destroy.
When she got to the MU, however, she didn't find herself on the winning side anymore.

She's very cool, though! :D I like her a lot. She's like 7ft tall and kicks absolute ass. I should draw her again, it's been too long...
