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.

Frost Walrus
Status: Repliforce	Stage: Snow Base	Weakness: Rising Fire	Special Weapon: Frost Tower

Frost Walrus will take up a lot of space in the large room. Whenever he punches his chest a few times, jump up the wall as he'll then jump down and slide along the ground. Jump off the wall just before he hits it. He will also sometimes fire out large ice spikes that will fly down from above and land in the ground. Shoot them to destroy them. He will also use a freeze attack and a variation of the ice spike attack. To defeat him, use the X-Buster or the Rising Fire. Use charged shots and jump over him whenever he slides across the floor, or walk up to him and hit him with the Rising Fire. Once you defeat him you'll receive the Frost Tower.

Jet Stingray
Status: Repliforce	Stage: Marine Base	Weakness: Frost Tower	Special Weapon: Ground Hunter

Jet Stingray will use strong attacks, so it will come in handy if you have energy tanks filled. You'll have to defeat him twice while you're on the jet bike before fighting him. He will hover above the water and will fire out several small stingrays that will crawl along the ground. Use a charged shot to destroy them before they hit you. He will also sometimes perform a dive attack that can cause heavy damage. Jump over him to avoid it. If he flies down into the water, he will fire out stingrays and will begin to suck X in towards him. To defeat him, use the Frost Tower. As he floats down from the sky, jump up and activate the weapon. He'll freeze for a few seconds and then will break out of the ice and fly back up the screen. He'll then hover down in the same position, so just repeat the process to destroy him. Once you defeat him you'll receive the Ground Hunter.

Slash Beast
Status: Repliforce	Stage: Military Train	Weakness: Ground Hunter	Special Weapon: Twin Slasher

Slash Beast will use fast attacks during this battle so you will have to be quick. He will often roar at X and then jump up above him. He'll then come slamming down into the ground to try and crush X. He will also often fire out two energy waves that will fly at X on an angle. If he charges up a purple beam, he will dash across the screen twice with it extended. Jump up the wall to dodge him. To defeat him, use the Ground Hunter. Each time you hit him with it he will perform his charge attack so jump up the wall and then repeat the process to defeat him. You'll receive the Twin Slasher once he's defeated.

Web Spider
Status: Repliforce	Stage: Jungle	Weakness: Twin Slasher	Special Weapon: Lightning Web

Web Spider will stay out of the screen often during this battle. When you see leaves falling down from the top, he will appear where they are falling. He will often fire out blue webs that will sap your energy away if they hit X. Dash and jump off the wall to dodge them. After his energy is half gone, he'll come down and create a large blue web. He'll then move around it while firing the blue webs and four small spiders at a time. To defeat him, hit him with the Twin Slasher each time he appears, and once he lowers down onto the web, just keep hitting him while dodging his attacks. You receive the Lightning Web once he's defeated.

Colonel
Status: Repliforce	Stage: Memorial Hall	Weakness: X-Buster	Special Weapon: N/A

Colonel will battle you once you defeat four of the eight bosses. He will use his beam saber as his primary weapon. He'll often dash across the screen and will then fire out three blue energy beams. To dodge them, dash under the first one, jump the second and then dash under the third. He will sometimes block your shots as well. If he disappears, dash away as he'll reappear on top of X and strike him. To defeat him, use charged shots and hit him as you dodge his energy beams, and remember to dash away when he disappears to avoid his sword blows.

Split Mushroom
Status: Maverick	Stage: Bio Laboratory	Weakness: Lightning Web	Special Weapon: Soul Body

Split Mushroom will use several attacks during this battle. He will begin by jumping up one of the walls and will then create six clones of himself that will eventually fly straight at X. Jump up the wall and dash-jump over them as they pass. He will then jump to the middle of the screen and cause purple rain to fall. He'll then create a mirror clone of himself and they'll perform several attacks while the clone is active. To defeat him, use the Lightning Web. Each time you hit him he'll jump to the opposite wall and begin to create clones. Hit him again and repeat the process to finish him off. You'll receive the Soul Body once he's defeated.

Cyber Peacock
Status: Maverick	Stage: Cyber Space	Weakness: Soul Body	Special Weapon: Aiming Laser

Cyber Peacock will only be visible for short amounts of time during this battle. Once he disappears he'll reappear over X and cause damage, so dash away every time he vanishes. He will also sometimes extend his feathers so that they cover a large range of the screen. Jump up the wall to dodge it. He will often fly up and use a radar to lock onto X. He'll then fire out missiles that will home in on X. Destroy the missiles before they explode. To defeat him, use the Soul Body and make sure that the clone part hits him. When you hit him he'll disappear and then reappear again. Dash away as he appears and then hit him again. Repeat the process to destroy him. You'll receive the Aiming Laser after he's defeated.

Storm Owl
Status: Repliforce	Stage: Air Force	Weakness: Aiming Laser	Special Weapon: Double Cyclone

Storm Owl will use some powerful attacks during this battle, so its important that you have energy tanks filled. He will fly out of the screen often and then reappear to perform an attack. He'll often fly up into the corner and fire out several energy balls that will all fly at X at the same time. Dash under them to dodge the balls. He will also sometimes try to grab X to slam him into the ground. If he lands on the ground he'll cause three huge tornadoes to fly around X to cause damage. If he flies to the center of the screen, dash to a corner as he'll fire out energy balls in random directions. He'll fire out three long energy beams from the top corners of the screen, dash to the left or right to dodge them. To defeat him, use the Aiming Laser. When he flies low enough, wave the target over him to lock on and then fire. Repeat the process to defeat him. Once he's defeated you'll receive the Double Cyclone.

Magma Dragoon
Status: Maverick	Stage: Volcano	Weakness: Double Cyclone	Special Weapon: Rising Fire

Magma Dragoon will use many fire and lava attacks during this battle. If you have managed to keep the Raiden Armor while facing him, just use it to either heavily damage him before it blows or to completely defeat him. He'll begin by charging at you and will use a fire attack. His attacks will involve him breathing fire across the screen which will be difficult to dodge, he will also create a small fire ball that will fly up and then down at X. To defeat him, use the Double Cyclone. Each time you hit him he'll jump over to the opposite side of the room. Follow him and repeat the attack to finish him off. You'll receive the Rising Fire after he's defeated.

The following three bosses will be fought in the Spaceport and Final Weapon stages.

Colonel
Status: Repliforce	Stage: Spaceport	Weakness: X-Buster	Special Weapon: N/A

Colonel will use the same attacks as he did during the earlier battle. He will have two new attacks, one where he'll stand in the middle of the room and generate lightning that will flow up from the ground. Stand between the gaps of the bolts to dodge them. He will also sometimes fire out a large purple energy blade that will increase in size at it moves across the screen. Jump up the wall to dodge it. His three blue energy blasts will also move faster this time. To defeat him, use charged shots from the X-Buster and hit him when he fires the blue and purple energy beams, and when he fires off the lightning attack.

Double
Status: Maverick	Stage: Final Weapon	Weakness: Double Cyclone	Special Weapon: N/A

When you meet Double in the final stages, he'll reveal his true identity and will become a large reploid. He'll be using very fast moves during this battle, so you'll have to be quick on your feet. He will fire out many energy balls and projectiles that will fly around and annoy you while he jumps around trying to crush X. Dodge the energy balls he fires by hovering in the air. To defeat him, use the Double Cyclone. Hit him as much as possible, and if your health becomes low, use an energy tank. Keep hitting him and use charged-shots to inflict heavier damage.

General
Status: Repliforce	Stage: Final Weapon	Weakness: Twin Slasher	Special Weapon: N/A

General is huge and will take up most of the room. You'll fight him not long after defeating Double. He'll fly around often while trying to crush X. He will often fly low across the screen. If he flies across at a low height, he'll stop in the center of the room and will crash down, causing a line of large blue flames to appear on the floor. Jump up one of the walls to dodge them. He will also sometimes fire out six blue energy beams from one of the corners of the room. Jump between the gap in the beams to dodge them. His largest attack will be him flying up to a corner of the room and then he'll fire out his fists which will fly across the screen. While they fly around, blue energy rings will fire out from his arms. To defeat him, hit his head with a blast from the Twin Slasher. You can safely hit him from the opposite wall when he performs his fist attack as well as jumping on top of the fists to get a closer shot, and you can hit him when he flies low. Make sure your energy tanks are high as you'll most likely need them.

When advancing through the last Final Weapon stage, you will have to fight all of the eight bosses again. Use the same tactics as before and you'll find that they are much easier to defeat the second time.

Sigma Part 1
Status: Maverick	Stage: Final Weapon	Weakness: Rising Fire	Special Weapon: N/A

Sigma's first form will be a grim reaper-style form. He will often appear and disappear during the battle. When he appears, he'll fire out several energy balls that will strike the walls and crawl down along the floor and then back up the walls. Try to jump up the walls to dodge them. He will also sometimes appear on the left or right wall and will then fly across the screen with his scythe extended. Dodge this attack by jumping up the opposite wall and staying at the very top until he disappears. To defeat him, use the Rising Fire. Each time you hit him he'll disappear and then reappear. When he reappears the third time, he'll be in one corner and will perform the scythe attack. Repeat this process to eventually destroy him without getting hit. Once you defeat him he'll taunt you be saying "Are you ready for round two?"

Sigma Part 2
Status: Maverick	Stage: Final Weapon	Weakness: Lightning Web	Special Weapon: N/A

Sigma's second form will look similar to his forms in previous MMX games. He'll use his scythe again as his primary weapon. He'll begin by jumping to the center of the screen and will throw his scythe so that it spins around the room. Dash under him and stay in the corner behind him to dodge it. He will then perform one of two random attacks. He will throw his scythe straight at X and once it hits the ground, it will generate green electric bolts that will flow across the floor. Sigma will then fire out four small spinning blades that will home in on X. Stay up the wall to dodge the blades and electric bolts. The other attack involves Sigma throwing the scythe into one corner of the room, then it will generate electric bolts up and down the wall. He will then jump to the other corner and will fire out two eye lasers that will cover the rest of the room. Dodge it by jumping up on the wall above Sigma and wait until he stops firing. To defeat him, use the Lightning Web. Try to hit his head so that you can easily dash under him when he jumps up. Keep hitting him with the Lightning Web and try to dodge his attacks as best you can. Once you defeat him the ground below X will explode and you'll reach the final room where Sigma's third form awaits.

Sigma's Final Form
Status: Maverick	Stage: Final Weapon	Weakness: X-Buster	Special Weapon: N/A

Sigma's final form will consist of five individual parts and will be extremely difficult to defeat. The two main parts are a giant robot head that appears in the lower left corner of the room and a large robot manning a gun that appears on the right side of the room. These two parts have their own energy bars, and both will need to be defeated in order to defeat Sigma. There will be three smaller heads, yellow, red and blue ones which will randomly perform their own attacks. The order of attacks will be as follows: The three colored heads will attack first, one of the heads will randomly attack while the other two are idle. The red head will fire out four sequences of fireballs. Jump up the other two heads to dodge the first two shots, then drop down to dodge the third, and then jump over the fourth. The yellow head will fire out energy balls at X from the top-middle of the screen that will become energy bolts once they hit a wall or the floor and will flow along the surface. Jump on top of one of the other two heads and jump and dash through the fire to avoid the balls. The blue head will be on one side of the room and will fire out a large ice-freeze blast. Jump up the other two heads to avoid it. After the three heads disappear, the large robot head will appear in the lower left corner. It will perform one of two random attacks. The first involves it blowing air against X to try and blow him into the spike wall on the right. Dash towards the head to evade the spikes. The other attack involves it sucking in large rocks to try and damage X. Stand close to the right wall so that if it sucks in the rocks, the blue head will appear in front of you and will block X from the head. Fire at the head with a fully charged shot to create the plasma field over the head and it will destroy most of the rocks before they fly out at X. Once the giant head disappears, the three heads will perform an attack again. The large robot on the right will next appear. If the blue and yellow heads appear lined up with each other on the left and you hear Sigma shout "The End!," quickly jump up the heads as he'll fire out a huge beam that will strike along the ground. His other attack will be a normal blast from his gun that will be directed toward the position X is standing. Lure the gun up to the yellow head so that it will fire straight ahead so you can fire off charged shots at the head of the robot. The sequence will then repeat itself. You will need to use charged shots on the giant robot head and the head of the large robot on the right of the room. Each one has their own power level, so you will have to destroy both of them individually. Follow the directions above to survive the three robot heads and keep firing charged shots at the two main parts. Once you destroy both parts Sigma will (for the fourth time) admit defeat and will explode, leaving X to escape from the Final Weapon before it blows. It will take a lot of practice and a few tries to beat Sigma, as out of the first four MMX games, this would have to be the toughest battle against Sigma.
