meh, could have guessed Halibel would have a shark theme, but didn't think much about it. The Shinigami commander (forgot his name) would probably beat all of them in the end just as easily as that monster thing the chimera sisters made.
Or, Hitsugaya, Soi Fon, and Shunsui would pull through. After all, two out of three haven't used bankai. Would have been badass if Zaraki was there though.
