Mega Man Powered Up/Alternate playthrough

Mega Man?
Stun weapons: None

Mega Man? can only be fought when you play as any Robot Master. He replaces him in his own stage and boss rematches in the 3rd stage of Castle Wily.

Mega Man?'s attacks are very easy to avoid. All he does is runs back and forth while firing 3 buster shots (1 on Easy) and jumping sometimes. He can also slide which you can easily avoid by jumping over him when he does that. After his HP drops below half (anytime on Hard) he'll start using charge shots which are also easy to avoid. On Normal Mega Man? will stand still when charging his buster but on Hard he keeps moving when charging it.

Guts Man: Fighting Mega Man? as him can be hard. Try to place a block in the middle of the arena and attack him at the right time. His charge shots can't destroy your blocks.

Oil Man: To deal normal damage to Mega Man?, you need to crash into him with your Oil Slider. But that's not without risk, because you can also get hit if you're not careful. Otherwise oil blob deals minimal damage. With blobs you'll take him out in 28 hits and with oil sled - in 14 hits.
