Things You'll Need
Instructions
Shoot at Bowser as fast as you can with fireballs by pressing the B button on the controller if you are Fire Mario. Also keep a safe distance as Bowser will shoot fire from his mouth that will come directly at you and he will throw hammers that will harm you if you get too close. It will take at least five fireballs to kill Bowser.
Run directly at Bowser if you are Big Mario. You will more than likely be hit and become regular Mario. Anytime Mario is hit when he is not in regular form, he starts flashing on and off. This indicates that Mario is invincible for about two seconds. Utilize this time to run past Bowser and grab the axe on the other side of the bridge. When you grab the axe, the game will automatically cut the bridge and Bowser will fall into the lava pit below.
Stand still if you are regular Mario. One hit will kill you if you are regular Mario so it is best to see if you can determine Bowser's attack pattern. Pay attention to when Bowser throws fireballs, throws hammers and when he jumps. If you are regular Mario the only way you can defeat Bowser is by running under or jumping over him. Learning Bowser's pattern will help you defeat him.
