Ah yes i remember the first time i got up to the final bosses......I was dissapointed cause i beat them first go (It took me about 12 goes to beat the ones on VIII). But then i was happy once again about three days later when i decided to fight them again....and i got killed! Woohoo! It was just a fluke the first time. (That was about two years ago and now i usually beat them in like, 2 seconds )

And yep that grand cross move can really stuff you up.
