Green Slime
Dr. Wily #: ??	Weakness: Mega / Bass Buster	Special Weapon: N/A

You will find the Green Slime at the end of the museum level. It will not move around at all during this battle. It will often fire out green blobs that will fly and slide towards you. Jump over them to avoid them. To destroy it, shoot at the large eye in the center of the body and the slime surrounding it will peel away for a short time allowing you to fire at the eye. It will then close up again. Keep shooting at the eye when it is exposed and this battle should be over quickly.

Cold Man
Dr. Wily #: 83	Weakness: Lightning Bolt	Special Weapon: Ice Wall

Cold Man should be the first boss you take on. He will often create and ice wall and push it towards you. When it hits the wall, it will bounce back towards him. If it hits you it will cause damage, so dodge it by jumping over it as it slides past you. He will also often fire out a small cloud which will fly towards you. If it catches you, you won't be able to fire or jump for a few seconds, leaving you open to the ice wall attack. He will also sometimes make an ice wave to come out of the ground and it will freeze you if it hits you. To defeat him, use the Lightning Bolt if you have it, or use the Rock/Forte Buster if you don't. Keep shooting him as he makes the ice walls and jump behind him if he jumps forward to ensure that the wall won't hit you. Shoot the small cloud when it appears. Cold Man shouldn't be too difficult to defeat. You will receive the Ice Wall weapon when he is destroyed.

Burner Man
Dr. Wily #: 86	Weakness: Ice Wall	Special Weapon: Wave Burner

Burner Man can be difficult to beat the first time. He will constantly be charging across the ground to try and push you into the spikes. Jump over him as he passes to avoid him. He will also sometimes jump up and hover in the air for a few seconds. He will then fly down straight at you. Dodge him by sliding/dashing away when he charges. He will also often jump up and fire out three bear traps that will stop you from moving if you touch one. Once the traps are set, he will slowly jump across the screen firing his wave burner weapon. He will also often stand still and throw bombs at you. To defeat him, use the Ice Wall. When he is going to fly at you from above, create the wall and stand next to it so that he will fly through it and take damage. When he throws bombs or is firing his wave burner, create the wall and push it towards him. It will push him away from you, so follow him to see him land on the spikes and take damage. You can also damage him by creating the wall as he dashes across the room and flies through it. After some practice he shouldn't be too hard to beat. You will receive the Wave Burner weapon once you defeat him.

Pirate Man
Dr. Wily #: 85	Weakness: Wave Burner	Special Weapon: Remote Mine

You will fight Pirate Man underwater. He will jump down in a bubble and attack. He will begin by firing out three remote mine projectiles which will fly towards your direction. Dodge them by jumping over them and staying away from their explosions. He will also often encase himself in a bubble and bounce around the screen to try and ram you. If the water level of the room becomes low, he will pump it back up to the top of the screen. To defeat him, use the Wave Burner. When underwater it will only fire out bubbles, but it will still damage him. Keep shooting him while dodging his projectiles and by staying close and firing as he creates the bubble, you should burst the bubble and cause damage before he can fly around the room. When you defeat him you will receive the Remote Mine.

Ground Man
Dr. Wily #: 84	Weakness: Remote Mine	Special Weapon: Spread Drill

Ground Man will tunnel into the room and attack. He will jump at you and become an small tank with his drills pointed straight out and he will try to ram you as he charges across the room. He will also often dig into the ground and jump up under you. He will sometimes fire out his spread drill weapon which will split into smaller drills if you shoot it. He will also often jump up into the roof and you can see him moving around in the roof. As he moves above you, quickly slide or dash to the side as a huge drill will shoot down above you. He will do this about three times before jumping down. To defeat him, use the Remote Mine. When you shoot it at him it will stick to him. Fire a second time to detonate it. Hitting him successfully will take some practice, but make sure that you only set the mine off when he is at his normal form, not the tank. When you defeat him you will receive the Spread Drill.

Tengu Man
Dr. Wily #: 57	Weakness: Spread Drill	Special Weapon: Tengu Blade

Tengu Man will fly down out of the sky and attack. He will be constantly flying around the top of the screen. He will often charge across the screen and try to fly through you. Dodge him by jumping over him as he passes. He will also sometimes fire out his tengu blade which will grab you in a tornado and take you over to the hole and try to drop you into it. He will also sometimes fly down and shoot his tengu blade towards you which will cause damage. To defeat him, use the Spread Drill. When he begins to fly down to the ground, shoot a drill at him and he will fall to the ground. He will then fly back up to the top of the screen and fly around again. Wait until he lowers again before firing. When you defeat him you'll receive the Tengu Blade.

Magic Man
Dr. Wily #: 87	Weakness: Tengu Blade	Special Weapon: Magic Card

Magic Man will use a spotlight to make his grand entrance. He will charge across the screen to try and hit you, and will often fire out large blue balls that will become the little men if you shoot them. If this happens, just shoot the little men to destroy them. He will also often fire out his magic card which will steal some of your health if it hits you, so jump over it when it flies at you. He will also sometimes jump up and shoot down an orange ball at you which will explode on impact and three little birds will fly out and fly around the room. To defeat him, use the Tengu Blade. An effective way is to dash/slide when using the weapon so that you charge at him and fly through him causing damage. Otherwise, just keep shooting him as he dashes across the room. When you defeat him you'll receive the Magic Card weapon.

Astro Man
Dr. Wily #: 58	Weakness: Magic Card	Special Weapon: Copy Vision

Astro Man will make a nice little entrance through some sort of teleport wall. He will be constantly flying around the room to try and ram into you. He will also often disappear and reappear in another location. When he moves to the center of the screen, the two small balls rotating around him will fly down in formation and try to hit you. He will then fly around the room and shoot small green energy balls at you. He will fly to one corner and create a clone of himself which will also fire at you. He will then fly to the other corner and create a second clone. He will also often fly down and shoot out small mine-type enemies which will jump out of the ground until you destroy them. He will make three of them before teleporting again. To defeat him, use the Magic Card. Shoot up as he flies above you and when he flies low. Don't shoot him as he makes the mine enemies as it won't work. Shoot him when he creates his clones to reduce the amount of enemy fire you'll have to dodge. When you defeat him you'll receive the Copy Vision.

Dynamo Man
Dr. Wily #: 82	Weakness: Copy Vision	Special Weapon: Lightning Bolt

Dynamo Man can be difficult at times. He will appear at the top of the screen and attack. He will start by jumping towards you, and will then charge back and forth across the screen. Jump over him with he dashes around. He will often fire out three energy balls, one which will fly at you and the other two will fly up to the ceiling and cause huge lightning bolts to shoot down. He will also sometimes jump across the screen and fire out five energy balls which will one at a time fly towards you. He can also fire out large electric walls which will fly across the screen towards you which can be only be destroyed by the clone's fire. Often he will jump up to the top of the screen and enter a small chamber which will regain his energy. Jump on the platforms that appear and destroy the two panels beside him to bring him back down. To defeat him, use the Copy Vision. When he stops dashing, create the clone to fire at him as he shoots his energy balls. When the clone is active, the energy balls will home in on it and cause no damage! Make sure to destroy the two panels when he jumps to the top of the screen. When you defeat him you will receive the Lightning Bolt.

The following bosses will be encountered in King's fortress.

Conveyer Belt
Dr. Wily #: ??	Weakness: Copy Vision	Special Weapon: N/A

The conveyer belt boss takes up the entire space of the room. The actual machine consists of a platform attached to a large ball-shaped object and is suspended above lava. A robot monkey will often jump down and hang from the wire while throwing rocks at you. Occasionally the ball-shaped object will fire two missiles out at you. Small mines will also often jump out of the lava and roll across the screen. To defeat this boss, use the Copy Vision. First, create the clone in front of the ball-shaped part and then jump onto the platform. You will notice that it will fall and the ball will rise. A creature will pop its head out of the object and will be hit by the clone's fire. This is the bosses' weak point. Dodge the missiles it fires and just ignore the monkey, as it will often throw rocks at the clone, and not at you! Repeat the process to defeat the boss. Make sure that you don't fall into the lava as the platform can fall all the way into it.

King Tank
Dr. Wily #: ??	Weakness: Mega / Bass Buster	Special Weapon: N/A

The King Tank will not be easy to beat. First, it will often fire out shots from the main cannon mounted on the front, it will also often shoot out large bombs that will fall down from the top of the screen. It will also occasionally open up its rear hatch and spew out the little men that immobilize you if they touch you. If you are on the same platform as the Tank it will also often charge at you to slam you against the walls. To defeat it, first shoot the cannon when it fires at you and eventually you will destroy it. Next, shoot the rear hatch when it opens and it will eventually blow up. Remember to stay below the tank often as it can only reach you with its bombs when you're below it. Once the gun and hatch are gone, shoot the upper part that opens when it fires bombs. Once the three parts are destroyed, the tank will explode. You will only need to use the Rock/Forte Buster against the tank.

King Fighter Carrier
Dr. Wily #: ??	Weakness: Mega / Bass Buster	Special Weapon: N/A

The Fighter Carrier is more difficult to beat than the tank. Here you will have to be constantly jumping across the small platforms that rise from the ground to stay in the battle. The ship will come down and part of it will come off, revealing its weak point. It has three main attacks, one where its front cannon will open and will eventually shoot out a huge red beam which is difficult to dodge, but if you are using Mega Man, use Beat to shield him from the blast, and if you're using Bass, keep shooting the gun and you should quickly destroy it before it can fire. The ship will also launch missiles shaped like fists which will destroy any platforms they hit. It will often fire out powerups encased in bubbles, but it will also shoot out bombs which when set off, will create a blinding flash and you won't be able to see anything for a few seconds. To defeat it, use the Rock/Forte Buster and keep shooting the small silver head of the ship. It will take a long time, but just don't stop shooting it and it will eventually explode.

King Part 1
Dr. Wily #: ??	Weakness: Mega / Bass Buster	Special Weapon: N/A

You will fight King soon after the Fighter Carrier. He will have two main attacks. His first will be the most annoying, as he will use his shield and absorb the shots you fire at him. He will then shoot back a large energy beam at you which causes heavy damage. Try not to shoot his shield. He will also often move his shield and fire out huge 'x' shaped projectiles which cause heavy damage as well, so try to dash/slide out of their way as they fly towards you. He will also sometimes jump across the screen. To defeat him, use the Rock/Forte Buster on him when he fires out the projectiles. Try to dodge them as best you can, and eventually Protoman will appear.

King Part 2
Dr. Wily #: ??	Weakness: Lightning Bolt	Special Weapon: N/A

Once Protoman destroys King's shield, he will take out his axe and continue to fight you. He will now charge at you spinning his axe in an effort to cut you down. He will also slash at you if you come too close to him. He will be constantly jumping around the screen. To defeat him, use the Lightning Bolt. When he is electrocuted, wait for him to go back to normal before firing again. Also make sure to use the Generator item to reduce the amount of weapon energy spent each time you fire so that you will have enough to finish him off.

Mega King
Dr. Wily #: ??	Weakness: Mega / Bass Buster	Special Weapon: N/A

King will now enter the combined robot form of the two previous bosses and become difficult to beat. The attacks he will use are similar to the ones that the King tank and Fighter Carrier used, so you shouldn't be taken by surprise much here. If you are using Mega Man, a platform will appear and you can use this to shoot charged shots at King's head to damage him. If you are using Bass you'll need to do a double-jump to reach him. If the small red cannon appears out of the chest, use the Beat shield with Mega Man to avoid the massive blast it will fire, or destroy the cannon quickly with Bass. If you can't reach him with Bass, fire diagonal shots at him and when at the right position you should hit him. Be careful of the bombs he fires out, as there isn't much room to move around in. King's fate once you beat him will be different depending on which character you're using.

Before battling Dr Wily, you will have to fight the first eight bosses again in a certain order. Refer to the guides above to defeat them again.

Dr. Wily Part 1
Dr. Wily #: ??	Weakness: Mega / Bass Buster	Special Weapon: N/A

Dr Wily's forms will be similar versions of the forms he had in Mega Man 8, but he will have new attacks. The first form is a large skull-ship, which will often fire out two missiles which you must jump over to avoid. It will also fire out a large buzz-saw projectile which will fly across the floor or bounce around the room. Jump or slide under it to avoid it. If the ship begins to vibrate, it will fly forward to try and hit you. Using Mega Man, slide under him and quickly slide back under him when he flies back to the right. If you're using Bass, stay on the left and double-jump up to avoid him. Once he stops moving, he will fire out small blue projectiles which you can dodge by jumping and sliding out of their way. It will also often charge up energy in its mouth and fire out a large beam. Dodge it by waiting a few seconds and then jumping up to avoid it. To defeat him, use a charged shot or normal fire on the cockpit of the ship where you can see Dr Wily's face. This is his only weak point. Don't be too relaxed when you beat him, as the battle isn't over yet.

Dr. Wily Part 2
Dr. Wily #: ??	Weakness: Magic Card	Special Weapon: N/A

When using Mega Man, Dr Wily's final form will be extremely difficult to beat. He will be constantly teleporting around the room. He will fire out one of three different types of attacks when he appears. One is four white energy balls that will fly toward you, so avoid them by dashing or sliding away from them as they fly toward you. He will also often fire out several energy balls that will fly out in a strange formation. Try to dodge them by staying in one of the gaps they leave open. He will also sometimes fire out four small bombs that will home in on you and explode on contact. Destroy them before they can hit you. To defeat Dr Wily, wait until he teleports low to the ground, and then shoot his face in the cockpit with the Magic Card. Using Bass, you can double-jump to reach him when he is higher, but with Mega Man you'll just have to wait until he is low enough. Once you beat him the ending will be different for Mega Man or Bass.
