All 3 phases: Counter for stars, then dodge the next punch and star punch for 7, then counter until you think it would be enough stars for the remaining HP, then dodge and star punch again.
This stage will be tough if you get any pattern other than the jab and single-uppercuts. Solution? Get just that! (Hooks ruin my life) (also its funny how mistermaster didn't color in the KD sprites or block sprites, and obviously and painfully ripped bald bull sprites as well)
