Mega Topman is fought in a metal arena with electric barriers on each wall. Mega Topman will move around the arena, if Mario runs into the giant Topman, he'll be harmlessly bounced backward, occasionally, Mega Topman will quickly spin, which will damage Mario if he gets too close. Mario must Spin Jump into Mega Topman, which will knock him backward, and keep knocking him back until the giant Topman hits one of the electric barriers. Every time Mega Topman hits an electric barrier, he will become invincible for a few seconds before Mario can hit him again. 3 hits defeats him.
