Mega Man 3/Wily Fortress 5

A very short stage. Grab the power-up items to refill some of your weapon energy (specifically, for the coming fight below, you'll want Spark Shock and Hard Knuckles.) Fall to the room below, and begin to do battle with your arch-nemesis.

Dr. Wily comes onto the scene in his Pinbot Machine. The machine walks slowly, and quite honestly, doesn't pose much of a threat. On the bottom of the machine, a dangling cannon can be seen. Rapid-fire the cannon with Spark Shock. You'll win Part One of this fight in no time flat.

For Part Two, Wily largely continues using the same strategy, but he can now "smash down" with the machine, crushing any would-be attackers. To put Pinbot to sleep, send a few Hard Knuckles into the glass dome holding Wily's control area. To make it easier to hit, you may want to wait until he lowers himself and performs the crushing move. Just keep your distance and let loose with the Hard Knuckles. Another strategy is to use the Rush Jet and just rapid-fire Wily's cockpit with your Arm Cannon.
