Supergirl returns?

[Obi-Ron]

I think Supergirl could be awesome, but it would take some balancing to keep the disparate elements of the character working well. As for a villain, i think Powergirl should be worked in as a rival, not necesarilly evil, but created/brought/changed by the main villain. As for who that villain would be, I've no idea.

That kind of sounds like what they did with Galatea on JLU.
