It is very easy to hit his face when you get used to it. After he does a left or right uppercut, hit him in the torso. He will be dazed. For the 1.5 seconds he is dazed hit him in the face. If your meter is full give him a super uppercut. He gets angry and doesn`t block his face, here is the time to attack. Dodge his attacks and quickly hit him in the face or torso until he is knocked down. Repeat this until he is defeated.
