28 Ice Girl Eight
Ice Girl Eight was ice / ice blast, of course. Ice was actually a great defender set, so I'd play Ice Girl on occasion, at least until I had several corruptors to choose from. After that, not as much. But I still liked my buffbot defenders, they were all fun to play and had good builds. Given time, I'm sure I would have gotten several more up to level 50. I had really wanted to play Fire Girl Three up, a fire/fire corruptor.
