Mega Man Powered Up/Fire Man

Boss: Fire Man
Stun weapons: Mega Buster (charged), Ice Slasher, Proto Strike

On Easy and Normal, Fire Man will shoot his Fire Storm at you. Hey may shoot one or two flames out. To avoid the single flame, simply jump over it. To avoid double flames, jump over the first and steer right when jumping above the second. Fire Man's special attack causes him to launch a powerful fire wave that moves across the screen. On Normal this wave ends once it touches a wall, but on Hard it keeps moving in the opposite direction and ends when it touches another wall. This wave can be frozen by Ice Slasher, which is also Fire Man's weakness. Like all other Robot Masters, he uses his special attack after his health drops below half, but on Hard he can use it anytime.

Guts Man: Fire can't get through Guts Blocks, so create one to defend yourself and attack when he hesitates or runs.

Oil Man: Shoot an oil drop at him while you're in mid-air and dodging his second type of attack. When Fire Man shoots only one, just dodge, not attack. Because Oil Man is weak to Fire Storm, his attacks will deal great damage to you, so watch out.
