Hint: Defeating Quick Man

The enemy robot clones operate on flat, uninterrupted rooms in the fifth Skull Castle Stage. Quick Man was specifically programmed for this room. The room in which he is found in his own stage has 2 two-stage rises, causing him to run in place for about three seconds on the upside of a step or wall. Use this as an opportunity to deliver a some Arm Cannon shots to defeat him.

Hint: Defeating Dr. Wily the second time

Most weapons such as the Mega Buster will not work on Dr. Wily during the second battle with him. Instead, hit him with the Bubble Lead until he is defeated. Once he is defeated, the game will end.

Hint: Defeating level 4 boss

There are two ways to defeat the Dr. Wily level 4 boss. One way is to use Crash Man's weapon on the walls and the boss. In doing this, you will not have enough weapon energy remaining to finish off the boss so you'd have to keep getting hit and dying. When you start back at the check point, find some more weapon energy to refill Crash Man's weapon, then return to the boss. The ones you destroyed will be gone but the walls will remain. You should then be able to defeat the boss. The other way to defeat the boss is to ensure you have some #1 and #3 remaining. Use #1 to fly up, shoot the enemy on the right, jump down, shoot that one, use #3 on the wall, go up, head to the bottom right, use one on the wall and the boss, shoot the enemies on the left, then use #1 and fly up. Use the last bit of energy remaining on the last one.

Hint: Robot Masters' weaknesses

As with all Mega Man games, each Robot Master can take a certain number of hits from each weapon while some are not affected by other weapons (bullet, missile, Atomic Fire). In the fifth Skull Castle stage (or throughout the game), learn what weapons do the most damage to specific boss. Some tips are below:

Robot MasterWeakness
Metal Mancan be defeated with one hit from his own Metal Blades (which only use half of an energy unit each). Metal Man is also easily defeated by about six to fourteen Quick Boomerangs.
Crash Mancan be defeated by running in an infinity symbol pattern (an elongated sideways figure 8) and shooting him with either an Arm Cannon or Quick Boomerang shot fourteen times or the Air Shooter twice.
Air Mancan only take two to three Leaf Shields into his intake valves. Wait until he fires his salvo of 3 Air Shooter attacks. He then jumps to the other side of the room to continue his assault. Hit him from behind. His tornadoes are bulletproof.
Flash Mancan be fooled into walking into a Crash Bomb placed into the left wall. Wait on the upside the until he reaches you. Place the bomb when he is two thirds of the way there. If he reaches you, stay there. Even with the Time Stopper on, the damage you do to him will more than make up for what he does to you. If it works on time, it will only take one Bomb. Otherwise, It may take two or three attempts.
Wood Manmake a direct hit with Crash Bombs on Woodman's orbiting Leaf Shield. You will take him out faster than you would with the Metal Blades. One to two hits on the shield itself will defeat him. If you hit him through the leaves, it will take more hits and weapon energy. If you use Metal Blades, it will take more than two weapon units worth to blast an unshielded Wood Man.
Bubble ManQuick Boomerangs will easily take out Bubble Man. He can also be taken out by Metal Blades as he descends from his swim.
Heat Mancan be cooled off with the Air Shooter, Arm Cannon (P), or Bubble Lead. Use him as a toreador or matador uses a bull. After a direct hit, he flames up and turns into a three-stage fire missile, aimed at your last spot before his conversion. Leap over him and counter his attack with an immediate direct hit, which forces him to perform the same feat again. Continue this bullfighting technique until this "heat wave" dies down.
Quick Mancan be defeated by using his weakness (see "Quickman's Flaw") against him and/or using the Time Stopper (F) in the room. It hurts him to be slowed down or have his program halted. If you can successfully "super-charge" up (hold B until the flashing weapons meter changes from a yellow flash, to a light blue flash, to an intense white flash) the Atomic Fire (H) and hit Quick Man with it, he can be defeated in two hits, removing eight units of white-hot weapons energy each. Do not worry, as you have twenty-eight energy units in all.

Hint: Recommended robot master order

Robot MasterTips

Flash ManWith two to three Bubble Lead (B) hits.
Quick ManWith all of the Time Stopper (F) and approximately seven Arm Cannon (P) shots.
Metal ManWith approximately seven or so Quick Boomerangs (Q).
Wood ManWith approximately seven Metal Blades (M).
Air ManWith two to three Launchable Leaf Shields (W).
Crash ManWith two direct Air Shooter (A) hits.
Heat ManWith about four to seven Bubble Lead (B) hits or four Air Shooter (A) hits.

Hint: Recommended robot master order (alternative)

Robot MasterTips
Metal ManUse regular shot and dodge his blades. Learn his pattern.
Bubble ManFour hits from the Metal Blade.
Heat ManTwo hits from the Bubble Lead.
Wood ManOne hit from a fully charged Heat Blast. Hold down the button and wait until he throws his leaves at you. Jump over it and hit him as you come down.
Air ManTwo shots of the Air Shield.
Crash ManTwo shots from Air Blast.
Flash ManFour Metal Blade hits.
Quick ManUse Flash Stopper to knock off half of his energy, then fire a regular shot. Be quick and watch his pattern. The same works for the fifth level of the Dr. Wily stage, when you fight them again. When you fight Metal Man, one shot from the Metal Blade will suffice.

Hint: Recommended robot master order (second alternative)

Use this order if you want to get 100% in this game by getting all 1-up Mega Man lives, all Energy Tanks, all weapon pellets and all energy pellets.

Robot MasterTips
Air Man (uses Air Shooter)Use the Mega Buster.
Crash Man (uses Crash Bomber)Air Shooter.
Metal Man (uses Metal Blade)Mega Buster.
Heat Man (uses Atomic Fire)Mega Buster or Air Shooter.
Bubble Man (uses Bubble Lead)Metal Blade.
Wood Man (uses Leaf Shield)Metal Blade or Crash Bombs.
Flash Man (uses Time Stopper)Mega Buster or Crash Bombs.
Quick Man (uses Quick Boomerang)Time Stopper and Mega Buster.

Hint: Recommended robot master order (third alternative)

Robot MasterTips
Bubble ManUse your average weapon (Mega Buster).
Heat ManUse Bubble Lead.
Wood ManCharge up Atomic Fire to full and kill him in one hit.
Air ManUse Leaf Shield.
Crash ManUse Air Shooter (two hits).
Flash ManUse the normal Mega Buster.
Quick ManUse Time Stopper which will drain half his life, then pelt him with Mega Buster shots.
Metal ManUse Quick Boomerang.

Hint: Unlimited Atomic Heat in Crash Man's stage

After you have obtained Heat Man's weapon, go to Crash Man's stage. In the very first area where you are teleported, climb the first two ladders, jump on the highest pipe, and select the Atomic Heat. Run to the wall and begin pressing A and B together rapidly (try not to charge), jumping and shooting while facing the wall. You must have some Atomic Heat weapon energy in order for it to work. If it does not work and you cannot fire anymore, just get a weapon refill from the enemies around that area and try again. If done correctly, your Atomic Heat will automatically refill itself and you will never run out no matter how long you charge. This trick will not work on any other stage or using any other weapon.
