X'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.

At the end of the first stage Zero will appear followed closely by Sigma. His form will be that of a huge floating head that takes up a lot of room on the screen. After taunting X, the battle will begin. He'll use several attacks, those of which include two energy balls coming out of his eyes, after a few seconds they'll fly towards you so get ready to move quickly. He'll also often open his mouth and charge at you, back up to the door on your left to dodge him. After performing an attack, he'll disappear then reappear on the right. Sometimes he'll slowly move towards you while spewing out heaps of small energy balls. Stay up against the door and crouch down to dodge them. If he stays put on the right and you hear a charging sound, quickly jump up the wall as he'll fire out a huge purple beam that consumes most of the screen. To defeat him, you'll need to fire at his mouth when it's open. Use the charged X-Buster to inflict heavy damage on him, and always be ready to move. He shouldn't take too long to beat.

Grizzly Slash
Status: Infected	Stage: Weapons Facility	Weakness: Spike Ball	Special Weapon: C-Shot
Grizzly Slash will drop into the large rocky room to confront X. Once the battle begins, he'll whip out three small yellow blades which can cause damage if they hit X. Drop down into the depressions in the ground to dodge the blades. He'll use this attack often, so be ready for it. He'll often jump around to each higher ground levels, duck under him and crouch down in the depressions to dodge him. Use charged shots from the X-Buster to beat him, his weakness is the Spike Ball, so during the next battle against him, use that. Once his health goes down a bit, he'll jump up out of the screen. Keep moving as he'll drop down with his drill extended and he'll drill into the ground and disappear. He'll then either appear out of the wall and slash at X or his head will pop up out of the ground and he'll fire off his drill. Keep moving to dodge him. Once he jumps down and re-enters the room, he'll use a new slash attack, in which a large yellow crescent-shaped blade will fly towards X. Try to jump up the wall to dodge them.

Duff McWhalen will battle you in an underwater room, so you'll be able to jump higher here. He'll appear on the right of the screen and he'll stay there for the first part of the battle. He'll start by firing out large ice blocks that move across the screen towards X. He'll follow X around and try to crush him against the left wall with the ice blocks. After firing out a long line of blocks, he'll fire out a small blue cloud that will crawl along the blocks. Jump up to dodge it. After the cloud disappears, he'll draw the blocks back toward him. You'll notice that the configuration will change and large ice-spikes will also be drawn towards him. Jump up over them as they pass underneath, and watch out for the small missile he also fires out. Use the C-Shot to inflict heavy damage on him, each time you hit him, all the ice blocks on-screen will explode. Once his health is almost gone, he'll move to the left side of the screen. From here he'll fire out a sequence of ice blocks which move very fast across the screen and plow into the spikes on the rear wall. Make sure that you don't get stuck on one of them, otherwise you'll lose instantly. Just keep firing at his face and you should finish him off fairly quickly. You receive the Gel Shaver, F-Splasher and Hydrogen once he's defeated.

Dynamo
Status: Mercenary	Stage: MH HQ	Weakness: X-Buster	Special Weapon: N/A
After beating two bosses you'll have to face Dynamo for the first time. He'll fight you in a small room, and you'll lose one hour for fighting him, but don't worry about that. He'll often use his purple whip-type weapon, he'll throw it towards you and after a few seconds it'll return to him. Jump up the wall to dodge the whip. He'll also try to block your shots when you fire at him, so try to hit him just as his whip returns. If he jumps up across the screen, once he gets close to X he'll whip out a large attack which is difficult to dodge from below, so try to jump up the wall and then over him to dodge it. To defeat him, use the X-Buster. Keep firing off charged shots at him, the plasma blasts should inflict further damage on him.

Squid Adler will use heavy electric attacks during this battle. He'll begin by firing out three electric bolts, one forward, above and below him. Once they hit a wall or the floor, energy balls will appear and crawl along for a short distance. He'll also often create a large electrified block in the center of the room which will damage X if he touches it, so stay clear. If he jumps down on the ground he'll punch down and create a long electric beam that covers the entire floor, jump up the walls to dodge it. If he jumps up to the side and extends his long tentacle-like beams above and below him, he'll shoot out numerous electric beams that will fly across the screen. Stay low and below him to dodge them. To defeat him, use the Gel Shaver. Each time you hit him he'll be stunned for a second, he'll then most likely try to ram into X, so be ready to move and fire again.

Izzy Glow
Status: Infected	Stage: Laser Lab	Weakness: Tri-Thunder	Special Weapon: F-Laser
Izzy Glow will enjoy teleporting around during this battle. He'll often fire out a missile that will home in on X, so move around it as much as possible as after a few seconds it'll explode. He'll teleport around to random locations so it'll be difficult to hit him at times. Use the Tri-Thunder to defeat him. You can fire the weapon far away from him as the bolt flying up will hit the roof and the energy ball will fly into Izzy. Once his health is about half gone, he'll begin to use a large laser attack, where he'll create a huge laser streaking across the screen horizontally or vertically. Try to hit him before the beam gets too close. He'll also sometimes fire out small energy balls that will line up on the floor. Izzy will then fly to the opposite wall and recall the balls. Jump up the wall to dodge them. After a few shots he'll begin to teleport like crazy, try to dodge him and wait until he calms down and resumes his other attack patterns. Once you defeat Izzy you'll receive the F-Laser, the C-Flasher and the Laser Device.

Dark Dizzy
Status: Maverick	Stage: Observatory	Weakness: F-Laser	Special Weapon: Dark Hold
Dark Dizzy will float up in one of the corners of the room for most part of this battle. He'll often fly back and forth and up and down, so try to avoid him as he moves. He'll also sometimes charge at X and grab him. He'll then start sapping X's energy while replenishing his own, so try to avoid him. Dizzy will also often create several smaller bats that fly out to annoy X, just fire off a charged shot of the X-Buster to easily destroy them all. Defeat him with the F-Shot. He'll move around when you fire the missile, but you should easily be able to home in on him, he doesn't move too fast. You'll run out of weapon energy before all his health is gone, so use the X-Buster to finish him off. After his health is almost spent, he'll use a new attack where he'll fire out a three large multi-colored rings that slowly move towards X. Duck below and jump over each one to dodge them. As soon as they pass, he'll charge up and will release an energy field that will freeze X for a second. Make sure that you're standing far way from him as he'll charge at X and try to grab him. Once you defeat Dizzy you'll receive the Dark Hold weapon and a Fuel Tank.

The Skiver
Status: Infected	Stage: Reploid Air Force	Weakness: Dark Hold	Special Weapon: Wing Spiral
The Skiver will battle you on the wings of a large airship. This means that you can fall off the edge, and he'll try to use this to his advantage. As one of the last top commanders of the remains of the Repliforce army, The Skiver will put up a good fight. He'll often charge at X and if he hits you X will fly back a fair way, try to keep away from the edge of the wings otherwise you'll be knocked off the edge. He also sometimes floats up and flies down at X, jump over him to dodge his charge attacks. He will also often fire out a blue clone of himself that will fly out and perform the charge attack. Jump over it to dodge it. Use the Dark Hold weapon to your advantage, it won't damage him, but it'll freeze him so that you can get a few charged shots off with the X-Buster. After his health is half gone, he'll often fly up out of the screen. You'll have to be constantly moving and jumping here, as he'll fly back from any direction to try and ram X. Make sure that he does not hit you when he flies straight up, otherwise you'll be knocked off the edge instantly. Once he reappears, he'll float above the wings and will shoot out large whirlwind projectiles that will damage and push X further back. Stay under him and fire off a shot when the whirlwind passes. This boss is tough, but with a little practice you should beat him. You'll receive the Wing Spiral, W-Shredder and an Orbiter Wing once he's defeated.

Dynamo
Status: Mercenary	Stage: MH HQ	Weakness: Wing Spiral	Special Weapon: N/A
Once you beat six bosses Dynamo will return for his final battle. You'll fight him above the Space Shuttle, and he'll use the same attacks as in the previous battle but he'll also have a new stronger technique, as well as more health. He'll punch the ground and create huge energy beams that consume about half of the screen, try to dodge it by staying to the side and keep dashing around before the beams appear. To defeat him, use the Wing Spiral. He'll be on the ground often, a good time to hit him is when he throws out his whip. Jump down next to him while the whip flies below and blast him quickly before it returns. Using the charged-shot will inflict further damage and you'll be able to hit him from further away. He shouldn't be too difficult to beat.

Mattrex
Status: Infected	Stage: Volcano	Weakness: Wing Spiral	Special Weapon: Ground Fire
Mattrex will make a fiery entrance before the battle begins. He'll mainly use strong fire attacks here, so you'll have to be fast on your feet. He'll often make short jumps across the screen, if he corners you, just dash under him when he jumps. He'll also often fire out a fire bouquet that lands a short distance away from him. Make sure it doesn't hit you. Use the Wing Spiral to defeat him. You'll need to stand right next to him to hit him successfully, or you could use the charged shot to hit him from a distance. As his health goes down, he'll start using stronger attacks. He'll often roll over and charge straight at you, try to jump up a wall to dodge him. If he jumps up on a wall he'll either charge down at you or fire out smaller but faster fire projectiles. If he drops down to one of the corners, he might perform a stronger charge attack that leaves behind large fire blasts flying up from the ground. Jump up into a corner to dodge him. He might also sometimes fire out a huge barrage of fireballs, jump up the opposite wall to dodge it. This boss will be tough to beat, you'll have to persist right to the end, but with practice you should beat him quickly.

Axle The Red
Status: Infected	Stage: Forest Maze	Weakness: Ground Fire	Special Weapon: Spike Ball
Axle The Red will enter the room surrounded by a large rose. He'll taunt you at first, then attack.

He'll also sometimes whip out a large spiked ball that'll bounce around the room. Try to stay out of its way. Use the Ground Fire to inflict heavy damage on Axle. Once his health is half gone, he'll begin to create another clone that will jump around the room. Try to stay up in the corners to dodge them. Axle might also shoot a red petal up out of the screen, then several other petals will float down from above. They move down in a pattern, so you should easily be able to dodge them. Be very careful now, as Axle will stand in a corner and whip out a long spike whip. If you touch it, X will be trapped and his health will gradually go down. You'll be stuck for several seconds, so make sure this doesn't happen. The clone might also use the whip attack, so be careful. Be persistent and keep hitting him as he lands from his jumps. A tough boss, but easily defeated with the Ground Fire. Once he's defeated you'll receive the Spike Ball, 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: Tri-Thunder	Special Weapon: N/A
Remember that annoying cyclops boss also known as the Shadow Devil in Mega Man and Mega Man 3? Well, the crazy creature has returned in X5 and he's stronger and harder than ever. Once the battle begins, his pieces will start flying in from the left. there are three different variations in the order that each block flies in, your biggest threat are the two lower blocks. Stay right at the edge up against the wall that the blocks are moving to and try to jump over the lowest block and duck under the second lowest. You will need a lot of practice before you can successfully dodge the blocks. Once the creatures reforms, he'll open his red eye and fire out two red energy balls, one at a time. They can be easily dodged. Once he breaks up into blocks again, he'll create a green outline of himself where he was standing, whatever you do, don't touch it otherwise you'll take heavy damage. The blocks will then slide over and reform on the other side of the room. Sometimes two columns of the blocks will move across and stay on one side, so that two columns are up against each wall. The two lowest blocks will then slide across at the same time, and will then continue up. Jump and duck under them to easily dodge them. He'll also sometimes become a large skull-type vehicle and will slide across the floor to a wall. Jump up the wall and use a mid-air dash to dodge him. He'll then jump back a short distance and extend spikes from his underside. Dash under him to dodge it. Once he lands he'll open his eye to look around. He'll jump around a few more times before breaking up again. To defeat him, use the Tri-Thunder. When he opens his eye, shoot it with a bolt to heavily damage him. Also when he becomes a skull and opens his eye, use that chance to hit him as you'll get heaps of hits in before he breaks up. This boss is extremely difficult to beat and will take you a long time to defeat, but it is possible so don't get disheartened.

Rangda Bangda II
Status: Maverick	Stage: Zero Virus S2	Weakness: Ground Fire / C-Shot / Tri-Thunder / Gel Shaver	Special Weapon: N/A
This boss is similar to the wall boss in the first Mega Man X game, but will be harder to beat. It has three different eyes, a green, red and blue one. The green one will shoot out heaps of small blue projectiles that can be very annoying, use the C-Shot to destroy the green eye quickly. The red eye will fire out two long energy beams that will spin around it and cover the length of the screen. You'll need to jump around the eye to dodge it. Use the Tri-Thunder to destroy it quickly. The blue eye will often charge straight at you, try to dodge it and destroy it with the Ground Fire. If two large walls close in around you, jump up one as spikes will appear on the floor once they stop moving. The red-orange sun-like object will come to life and move towards you. Jump back and forth across the walls to dodge it. Destroy it with the Gel-Shaver. Be careful, as once the sun is gone, the walls won't open again, and sometimes spikes appear up the sides of the walls. Once all four parts have been destroyed the wall will explode. This boss is tough, but it isn't as hard as the Giant Blob so it shouldn't take you too long to beat.

Zero
Status: Normal	Stage: Zero Virus S3	Weakness: X-Buster	Special Weapon: N/A
You will only fight this form of Zero if you're using X in the third final stage and if Zero survived the Shuttle mission and didn't become a Maverick. After arguing about each other's safety, the battle will begin. Zero will use moves that you wouldn't normally be able to use if you're playing as Zero, so be careful. He'll often punch the ground and cause large blue energy bolts to fly up the screen, they will be very difficult to dodge, just try your best. He'll also sometimes fire out two large ice-rings, then he'll slash out his Beam Saber which will shoot out a green beam which flies straight at you. Jump up the wall to dodge it. Your special weapons won't cause any damage to Zero, so you'll have to use the X-Buster. Charged Shots are a must, and try to have full energy tanks as you'll definitely need them. If you have the Ultimate Armor, use it, as the Nova Strike will help a lot. Constantly use the Nova Strike attack back and forth across the screen and you should beat him fairly quickly.

Maverick Zero
Status: ???	Stage: Zero Virus S3	Weakness: X-Buster	Special Weapon: N/A
You'll only have to fight Maverick Zero if the Shuttle mission failed and Eurasia's pieces fell down on Earth. Zero will become a Maverick, and you'll have to fight him in the third final stage. He'll use the same attacks as if he was normal described above, but he'll be a lot stronger. Again, the Nova Strike attack will almost guarantee you victory, so the Ultimate Armor is a must. You'll need full energy tanks, don't hesitate to use them if your health is low. Zero is labeled as a Maverick here but its uncertain if he actually was a Maverick, the big "W" in the background looks rather suspicious, doesn't it? Zero is very difficult and will take a while to beat, but he won't be much of a challenge if you have the Ultimate Armor. Just make sure that you don't waste any time in beating him, try to defeat him as quickly as possible as in this form he can perform a huge relentless attack with his Beam Saber where he'll fire out two huge green plasma waves that streak across the screen and are impossible to dodge. You can escape getting hit by using the Nova Strike, but it's instant death if you're hit once and Zero will keep slashing out the waves until you're out, so make sure you don't give him a chance to use it. Once you defeat him he'll return to normal before sacrificing himself to save X from Sigma.

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. Remember, the Ultimate Armor's Nova Strike will greatly assist you.

Sigma Part 1
Status: Maverick	Stage: Zero Virus S4	Weakness: Tri-Thunder	Special Weapon: N/A
Sigma will confront you at the end of the final stage in his spiffy-looking new body. He'll taunt you as usual, then the battle begins. He'll toss his cloak away and attack. He'll often charge straight at you and will then jump up the walls and then down again. Jump right up to the top of one of the walls to dodge him. If he lands in a corner and stops, he'll shoot out small energy balls that bounce towards you. Jump up the wall to dodge them. Once he fires out two balls at a time, the attack will end. Use this break to attack him. Use the X-Buster/Nova Strike or the Tri-Thunder to damage him. The Nova Strike will help a lot, but the Tri-Thunder will also do fine. Try to hit him when he's standing still, once he jumps up the walls, hit him from behind and jump over him as he comes down to land and hit him in the back. Once half his health is gone, he'll stand still and will create four floating Sigma virus drones that will float around him as he jumps up the walls. Try to destroy them as quickly as possible as they will damage X instead of infecting him. Sigma will also disappear and reappear on the right often. Once he reappears, he'll fire out a huge blue energy wave that causes heavy damage, so be ready dodge them. If he fires out two, jump up to the middle part of the wall so they fly past. He'll then start jumping up the walls again. This form of Sigma is much more difficult to beat than his previous forms, you'll need practice and skill to defeat him. The Nova Strike attack works very well, but you'll need to stay aware of his attacks, as he can easily beat you if you're not careful. Once you beat him his final form will attack.

Sigma's Final Form
Status: Maverick	Stage: Zero Virus S4	Weakness: X-Buster / Nova Strike / Spike Ball	Special Weapon: N/A
Sigma's final form is a gigantic humanoid-shaped body, so large that all you see of it is his head and upper chest. He'll taunt you a final time, then he'll attack. Two large hands will appear at the bottom two corners of the screen and will use several attacks. Often one or both of the hands will open and they'll fire out a large purple energy blast. Stay on the ground and duck to dodge it. They will also try to crush X and will move up and down the screen. If you try to attack the main body while the hands are active, it'll just disappear to dodge your attack. Don't touch the spiked knuckles as they also cause damage. One good way to destroy them is to stand on one and fire off charged shots at the other, sometimes they drop energy capsules once you destroy them. Once the hands leave the screen, the main body will attack. Four blue energy balls will appear from Sigma's forehead and will line up on the ground. After a second, they'll fly at X one at a time. Jump up the left wall and jump to the right once they start moving to dodge most of them. They'll charge one more time before disappearing, so get ready to move once you land. The main body will also sometimes create a very large purple energy block that takes up a quarter of the screen. The block will try to appear over X, keep moving to dodge it before it becomes solid. The block will then move to try and hit X, it should be easy to dodge. One of the hands might also come down the top of the screen and fire out huge orange energy beams down on X. Try to get out from under it before it fires. Once it fires, it'll move around a bit so jump up a wall to dodge the beams. Once the main body's attacks stop, the two hands will return and resume their attack pattern. To destroy him, use the Spike Ball or the Nova Strike. Blast the two hands as quickly as possible with charged X-Buster shots, and use the Spike Ball when the main body attacks. Jump up the wall and hit the red gem on Sigma's forehead to damage him. Keep dodging his attacks while firing, but if you use the Nova Strike, just jump up the wall and fly across his forehead, and keep flying back and forth to heavily damage him. This is the toughest form Sigma's ever had in any of the X games, and he'll be extremely difficult to beat. With practice and skill, you should manage to destroy him, just remember that the Nova Strike makes it so much easier. Once you beat him, sit back and enjoy the finale.
