Mega Man/Fire Man

An area filled with fire pillars, fireballs, and lots of bottomless pits. Fireman is largely stationary but fires large fireballs at Mega Man which turn into standing flame when they make contact.

Boss: Fireman
Fire man will pace back and forth, firing quick waves of powerful fire in sequences of about four shots. His attacks can be dodge by jumping over them, but know that each shot leaves a little spark on the ground that can also damage you. Be sure not to jump on them!

If you're facing Fireman with just the arm cannon, just hop over his shots and blast him. This method takes the most skill, since you'll be taking the most damage, so just keep at it until you can beat him. Remember that since his shots fire fast, you should hop over them while moving backwards (or forward, then back in mid-air). You won't have time to shoot from the ground, so make sure you time your shots as you are landing and taking off.

Using the Ice Slasher, you can defeat Fireman with ease. Dodge his shots if you wish, but you'll probably be able to kill him while just standing still and freezing him to death.
