Just try try try. I beat her after 10 continues. Use her basic moves that hit multiple times. Block like mad. You can't continue in Story mode. If you lose, it will branch out to Ending #1. If you win, you must fight her again, but Dizzy will be in Gold mode. Then You will get Ending#2. I need to get ending#2 becos it is a requirement to unlock Ending#3 for Sol. Who said SNK bosses are cheap?!? By continuing I mean trying over and over again. I have unlocked all anding for all characters. Yes, Boss I-No and Boss Dizzy are hard, but not impossible. I know. Normally I will use Sudden Death move, but Dizzy has none I hate playing over and over again. I have to start from beginning for Dizzy! I think that even if Dizzy had an Instant Kill move, you wouldn't be allowed to use it. Just use her usual multi-hit punches at close range and go for the Gamma Ray when you have the chance. Note: Trainers are for the weak, you'll beat it eventually and then you are the king. If only it is that easy. Wonder if the difficulty setting will affect storyline?
