Kid Buu is arguably one of the toughest main story bosses. He is incredibly fast, unpredictable, and relentless. His Vanishing Ball Ultimate Attack is extremely dangerous and can one-shot you if you're not careful. Focus on quick, burst damage combos. Don't try to out-trade him in long combos. Use your evasive skills frequently. Guarding is less effective against his rapid-fire attacks. Be patient and look for small openings.
