Calling foenix...

Geoff Johns on the Final Crisis - Legion of Three Worlds crossover :

Well, I think that's the wonderful thing about that Legion. I look at the Zero Hour Legion and there's a truly brilliant array of characters Mark and Tom created, like Gates, XS and Kinetix. They created a lot of new characters in that run. And so a lot of those characters will be used.
