Emerald, possibly, if she's convinced the heroes will give her better support than Cinder - or if she believes that being a baddie isn't worth it, as she thinks Salem is abusive compared to the kindness Cinder showed her.

Mercury is a maybe. The dark and tragic backstory ups the odds. He might join, if he is convinced that the heroes can provide him with some sort of satisfactory exchange, or if he is humbled - that is he is beaten, and goes, "fine, you win, I'll join you!"

Neo is a possibility, if Roman Torchwick is dead - or if she chooses to play Roman's game and withdraw from the battle entirely.

Heh. It would be cool if a human saves his life and simultaneously destroys his ideology by proving him wrong.
