Zero's Bosses

There are two listings of the bosses here, one for X and one for Zero. Each list has the bosses organized in an order which allows you to be able to use the correct special weapon or technique to defeat them with.

X's Bosses will include the boss' attack patterns as well as how to defeat them, but Zero's will just have the method of defeating them. The levels of each of the eight bosses will be determined by how many hours you have left. The lower the time remaining, the higher the boss levels will be.

Sigma
Status: Maverick	Stage: Statue Park	Weakness: Z-Saber	Special Weapon: N/A
Use the Beam Saber to damage Sigma, the Z-Buster will also help when his mouth is level with Zero. Jump at him and slash away when his mouth is open, but be ready to jump back if he fires out the blue energy balls or if he charges at you. Jump up the wall when he fires out the huge purple energy beam, jump back down when it stops to get off more shots. Rip into him each time to deal out heavy damage. He shouldn't be hard to beat.

Grizzly Slash
Status: Infected	Stage: Weapons Facility	Weakness: Twin Dream	Special Weapon: C-Sword
You'll have to hit Grizzly in his chest, so it might be hard to hit him at times. Try to stay down in the depression below him, stand next to him and rip away with the Beam Saber, you should be able to get in a few hits before he jumps up. Once he jumps out of the screen, keep moving and try to get in a hit as he flies down. Once he appears out of the wall or floor, stand back and rip into him before he disappears. Once he lands and starts firing out the large crescent shots, try to dodge them and concentrate on hitting him. You shouldn't have too much trouble beating Grizzly. Once he's defeated you'll receive the C-Shot, C-Sword and a Crystal Ball.

Duff McWhalen
Status: Infected	Stage: Ocean Floor	Weakness: C-Sword	Special Weapon: F-Splasher
Use the C-Sword to beat Duff McWhalen. You'll easily be able to hit him, just jump and fire to perform the spin attack. Each time you hit him the ice blocks he fires out will disappear so you shouldn't have trouble dodging his attacks. After plenty of hits, he'll move across to the other side of the screen. Try to dodge him as he moves across. Once he reappears, you'll have to be very careful, as if you get caught on the blocks he fires out you'll be thrown into the spikes on the rear wall. Stay far away enough so you can dodge the blocks, you can also jump up the wall above him and jump down while attacking his head. Avoid the blocks and you should beat him fairly easily. You receive the Gel Shaver, F-Splasher and Hydrogen once you defeat him.

Dynamo
Status: Mercenary	Stage: MH HQ	Weakness: Z-Saber	Special Weapon: N/A
After two bosses are defeated you'll have to fight Dynamo. After making his entrance the battle will begin. He'll use his whip attack where he throws the whip out across the screen, which then returns to him. He'll also often jump up and fire out two small energy blasts either side of him. After the first two, he'll drop down and fire off another two. Stay low then jump up the walls to dodge them. Use the Beam Saber's normal attacks and the C-Sword to beat him. Keep hitting him as much as possible, but stay away when he attacks with his whip and energy bolts. Be persistent and you should beat him fairly quickly.

Squid Adler
Status: Infected	Stage: Power Plant	Weakness: F-Splasher	Special Weapon: E-Blade
You'll need to be fast to dodge Squid's attacks. Try to dodge around his electric bolts, they'll be difficult to get around, but its better than just standing around. Use the F-Splasher attack to defeat him. Get close to him, then jump up and use the mid-air dash. Zero will fly through him and cause heavy damage to Squid. Once he regains his balance, he'll most likely charge at Zero, so get ready to move. Keep blasting him with the dash-attack, but try to dodge him as best as you can. Staying up the walls will help you to dodge most of the electricity. Once you defeat him you'll receive the Tri-Thunder, the E-Blade and an Energy Cart.

Izzy Glow
Status: Infected	Stage: Laser Lab	Weakness: E-Blade	Special Weapon: C-Flasher
Izzy Glow will be hard to hit without taking damage. You'll need to be quick to dodge his teleport attacks, and play around with the missile he fires so it blows before it can reach you. Use the E-Blade to destroy him. You'll notice that when Zero performs this attack, he won't fly directly up, he'll move to the side a bit, so perform the attack when you're standing a short distance from Izzy, otherwise you'll go too far and hit him, taking damage yourself. When he starts firing out the large laser blast, quickly hit him before it gets too close. His teleporting will be annoying but just wait until he stops moving before attacking again. Once he's defeated you'll receive the F-Laser, the C-Flasher and a Laser Device.

Dark Dizzy
Status: Maverick	Stage: Observatory	Weakness: C-Flasher	Special Weapon: Dark Hold
Dark Dizzy will be easy to hit no matter where he is during this battle. Don't wait for him to start attacking, just start hacking away with the Beam Saber. Also use the C-Flasher, it'll inflict heavier damage on him. The bats he fires out can easily be destroyed with the C-Sword. If you run out of the C-Flasher, if he or the bats hit you, the damage you take will restore its energy, so you can fire off a few more shots. You'll be able to hit him from any position in the room with the C-Flasher. If he fires out the large rings, jump over and duck under them to dodge them, and stay away from him when he performs his freeze attack. You shouldn't have much trouble beating Dizzy. Once you defeat him you'll receive the Dark Hold weapon and a Fuel Tank.

The Skiver
Status: Infected	Stage: Reploid Air Force	Weakness: Dark Hold	Special Weapon: W-Shredder
After questioning Zero about his battle with Colonel, The Skiver will attack. You'll need to be fast on your feet to dodge The Skiver's charge attacks. Once the battle begins, use the Dark Hold to freeze him. Hack away at him, you'll be able to cause a lot of damage to him before the weapon runs out. Once he starts moving again, by very careful, as he'll probably perform his sky dash attacks. If he punches you while he flies up, you'll get knocked of the ship, so jump and move around when he's not on-screen. Also use the C-Sword to get in shots from a short distance. If he fires out the large tornadoes, stay under him and hack away between each attack. A tough boss, you'll need skill to beat him successfully. Once he's defeated you'll receive the Wing Spiral, W-Shredder and an Orbiter Wing.

Dynamo
Status: Mercenary	Stage: MH HQ	Weakness: W-Shredder	Special Weapon: N/A
Dynamo will be tougher to beat this time around. He'll use the same attacks as he did in the previous battle, but he'll also use the large beam energy attack. Try to stay between the beams to dodge them. Use the W-Shredder attack to inflict heavy damage on Dynamo. He'll stay in the corners of the room for most of the time, so you shouldn't have too much trouble hitting him successfully. He'll probably attack once he regains his balance, so get ready to move. Use the C-Sword when he jumps up, you can also use the three-hit combo attack when he lands. A little tougher than the previous battle, Dynamo shouldn't be too hard to beat, but don't underestimate his abilities.

Mattrex
Status: Infected	Stage: Volcano	Weakness: W-Shredder	Special Weapon: Quake Blazer
Mattrex will be tough to beat, you'll need to be quick to dodge most of his attacks. He'll use a lot of fire attacks, most of them will be fairly strong, so its worth trying to dodge them. Use the W-Shredder to damage him heavily. Each time you hit him he'll be stunned for a few seconds. It'll take a while for him to stop flashing, don't fire again until he does. He'll probably try to get an attack in before you can perform the attack, so get ready to dodge him again. If he jumps up on a wall you won't be able to hit him with the W-Shredder, so use the C-Sword to damage him as much as possible. If he fires out a huge fire ball or charges at you, do a double-jump and you should be able to dodge him. Another tough boss, you'll need to be fast and skilled to hit him properly and dodge enough of his attacks. Once you defeat him you'll receive the Ground Fire, Quake Blazer and a Booster.

Axle The Red
Status: Infected	Stage: Forest Maze	Weakness: Quake Blazer	Special Weapon: Twin Dream
Axle The Red will use strong attacks during this battle, so be aware of what's going on. He'll start by jumping around, so try to stay away from him when he lands. Try to jump up the walls if he fires out the bouncing spiked balls. Use the Quake Blazer to inflict heavy damage. You'll need to stand right next to Axle so that you can get the shot in down on his head. Once you hit him he'll be stunned for a few seconds so stand back until he stops flashing. His jumps will be annoying, wait until he lands before performing the attack. Make sure that you don't perform the attack right on top of him, otherwise you'll land on his head and take damage yourself. Once he starts creating the clone of himself, be persistent and keep hitting the real Axle, this way he won't get a chance to attack you with his vine whip. A tough boss, but you should be able to beat him easily with practice. Once he's defeated you'll receive the Spike Ball, the Twin Dream and an Orbiter Engine.

The following bosses will be fought in the final three Zero Virus stages.

Shadow Devil
Status: Maverick	Stage: Zero Virus S1	Weakness: Z-Saber	Special Weapon: N/A
The Shadow Devil will be more difficult to beat with Zero than with X. You can try to use the E-Blade to hit the eye, but it's too risky, so just use the C-Sword. Jump over, hit the eye and quickly fall back before you land on top of him. Take advantage when he becomes a skull and hack away at the eye when it appears. The C-Sword attack will help you a lot during this battle, as most of the time you'll have to jump up to hit the eye. Learn the block movements and you should get the hang of dodging them. Don't hesitate to use an energy tank, just remember, whatever you do, dont touch the blob or the green outline it creates, otherwise you'll take massive damage. Again, this boss will be very challenging and will take you a while to beat.

Rangda Bangda II
Status: Maverick	Stage: Zero Virus S2	Weakness: E-Blade / F-Splasher / Quake Blazer / C-Sword	Special Weapon: N/A
Rangda Bangda will be tough to beat. If the walls close, wait until the sun object returns to its position and the walls open again, this way you can fight the eyes easily. Use the E-Blade on the red eye, try to hit it as many times as possible even if you do get hit, it'll take only a few shots to destroy it. Use the Quake Blazer on the blue eye, attack it once it stops moving, and if it gets too annoying, just use the C-Sword. Finish off the green eye with the C-Sword, keep slashing at it when it fires to easily destroy it. Leave the sun object to last, once it attacks, try to use the F-Splasher when it moves towards you. If you find that too difficult, just use the C-Sword. A tough boss, but it shouldn't be as difficult as with X, but try to have energy tanks with you just in case.

Mega Man X
Status: Normal	Stage: Zero Virus S3	Weakness: Quake Blazer	Special Weapon: N/A
You've probably never thought that this would happen, but here he is, Mega Man X listed as a boss. No, don't worry, he's not Maverick when you fight him, X and Zero just have their little argument that turns into a fight. Once the battle begins, he'll activate the Ultimate Armor, but thankfully he won't use the Nova Strike. X will use the X-Buster and the special weapons from X4, mainly using the charged shot attacks. He'll be constantly charging up the X-Buster, he'll fire off heaps of shots and will be very fast with the special weapons. The Double Cyclone attack will be the same, with two large cyclone beams flying out on both sides, jump up the walls to dodge them. If he uses the Soul Body attack, he'll stand still and the clones will fly out straight at you, but they should be easy to dodge. He'll also use the charged Frost Tower, stand far back to dodge the ice blocks falling from above. If you're familiar with X's Weapons from X4 you should know what to expect. Not looking from Sigma's point of view, but X does have a weakness - Quake Blazer. Jump down on him and use the attack to cause heavy damage. Keep persisting with the attack, but stand back if he starts using heavy attacks. After beating Sigma more than three times and crushing many of his Mavericks, this is the first battle that X will truly lose. Once you defeat him Zero will defend X from Sigma's following attack.

When advancing through the final stage, you will have to fight all of the eight bosses again. This time though, they'll all be on level 96 and will have double the amount of health than the first time. They will be tough to beat, but you can use the same tactics as before to beat them.

Sigma Part 1
Status: Maverick	Stage: Zero Virus S4	Weakness: E-Blade	Special Weapon: N/A
Sigma's two forms will be extremely difficult to beat with Zero. You'll have to build up your skill and practice what attacks work well against him, but believe me, it will take a long time to beat him, just don't lose hope. Once the battle begins, get ready to jump up the walls once he charges. A good time to hit him is when he flies down a wall to land on the ground. Stand in the center of the room and jump up as he passes underneath, then fire to use the C-Sword to cause damage to Sigma without taking any yourself. Jump up the opposite wall when he fires out the energy balls, after the third round passes, jump down and whack him before he charges. His weakness is the E-Blade, when you hit him he'll show electric damage and take more damage than from the Beam Saber. A good time to hit him is also when he jumps down, time it right so that you jump up high, whacking him as he flies under you. This way you should be up above him as he passes, so once you land you'll miss colliding with him. Once he starts creating the Sigma virus drones, you should easily be able to destroy them with sustained whacking with the C-Sword. If he appears on the right and fires out the huge blue plasma waves, stand on the left of the room and dodge them, wait until he reappears before attacking again. Remember, start the battle with two full energy tanks and don't use one during this part of the battle, after some practice, you should be able to beat this form without having to use one. If you need more energy, if you lose a life you'll be able to pick up a large energy capsule outside his room which fills a quarter of an energy tank. Save the two for the final battle. Once you defeat him his final form will appear.

Sigma's Final Form
Status: Maverick	Stage: Zero Virus S4	Weakness: Twin Dream	Special Weapon: N/A
Sigma's final form will be incredibly difficult to beat. It will help if you have Zero's Black Armor here, you'll inflict more damage with the Beam Saber and receive less damage from his attacks. First, when the battle begins, jump up on one of the hands and pelt away at it with the three-combo strike. You'll still be able to hit it while standing on top, keep hacking and you should destroy one quickly. If the other one still pesters you, destroy it as well, but remember to stay on top of one and don't stand on the ground between them. Once the main body attacks, you'll have to be very quick on your feet. His weakness is the Twin Dream, once the hands leave, switch to the weapon and active it. Jump up and attack, make sure the clone hits his forehead to cause damage. He'll fire out the four energy balls, jump up the left wall and wait until they begin to move, then jump way over to the other wall and jump over any other energy balls coming at you. Once they start moving again, dash quickly to the left and jump over the remaining ones. If the large purple block starts to appear, move around as much as you can until it becomes solid, then it should be easy to dodge. Keep attacking Sigma as much as you can, and switch back to the normal Beam Saber when the hands reappear. If the hand comes down from above, try to dodge it before it fires out the energy beams, once it does, stay away from it until it leaves. This is by far the most difficult battle you will ever have in any of the MMX games, Sigma will take you ages to beat, but practice makes perfect, so don't worry if you keep losing, at least you'll be getting used to his attacks. Keep trying, and remember, if you need to use the energy tanks, use them. If you lose, you can keep losing to his first form so that you can slowly build up your energy tanks again with the energy capsule outside his room. Even if you get the game over screen, you'll still have your energy tanks full if you continue. Keep persisting, and never give up. Once you manage to defeat him, congratulations, you'll have beaten the toughest boss Capcom have ever made, consider yourself a Mega Man Xpert!
