Sadly Lolipiece is right. The females normally don't do anything in final battles. Yellow being the only exception of that rule but Blue, Crystal, Sapphire, and Platinum did nothing, so if White gets cheated I won't be surprised. In fact I am expecting it to happen. It would have been cool to see her with Zekrom, but I said the same thing about Platinum and Giratina and look how that turned out. I feel bad for White. Other then the Gigi back stabbing and her time on the subway learning to battle, she hasn't really stood out much other shipping hints. Hopefully when BW is in volume form her chapters will get more attention. Like maybe some more adventures with Bianca or something.
Parena or Serecham both equal Serena+Pancham!
