Mega Man X/Bosses

Opening Stage
Vile in Mech Armor: This is a storyline battle, so you can't "win." Once your energy meter drops below a certain point, Vile will start shooting "energy nets" at you, making you unable to move. Once you're hit by one, the story will proceed and the level will end. Keep in mind that if you're hit enough times before being trapped by the "net" you can still die.

Chill Penguin
Weakness: Fire Wave Weapon Received: Shotgun Ice

Chill Penguin can shoot ice cubes across the screen at you as well as create miniature penguin ice sculptures. When he grabs the handle on the ceiling, he'll create a snowstorm and the sculptures will slide across the floor. Chill Penguin can also dash across the floor. The Fire Wave will make short work of him; just be careful when attacking as the Fire Wave has a very short range.

Spark Mandrill
Weakness: Shotgun Ice Weapon Received: Electric Spark

Spark Mandrill will frequently jump across the screen and try to crush you. He will also dash at you, swing across the ceiling and try to drop on you, and shoot Electric Sparks at you. Shooting Spark Mandrill with Shotgun Ice will momentarily freeze him and do significant damage to him. If timed correctly, you can continuously shoot Spark Mandrill with Shotgun Ice and he will not even be able to move before he dies.

Armored Armadillo
Weakness: Electric Spark Weapon Received: Rolling Shield

This battle is made much easier if you shoot Armored Armadillo with at least one Electric Spark; it will electrocute him and cause his armor to fall off, making it impossible for him to block attacks. Armored Armadillo will attack by shooting Hadoken-like fireballs and rolling across the screen at you. Simply move out of the way of his rolling and jump over the fireballs (or climb the wall) and Armadillo is a pushover.

Launch Octopus
Weakness: Rolling Shield Weapon Received: Homing Torpedo

Launch Octopus has two main attacks. He'll either fire torpedoes at you or leap across the screen and create a whirlpool vortex to pull you towards him. If he grabs you during this move, Lauch Octopus will begin to drain some of your energy and regain his. This can be countered by either dashing away from the whirlpool or by cutting off his extra tentacles with the Boomerang Cutter. By using the charged version of Rolling Shield, you can protect yourself from torpedoes, but in order to hurt Octopus you must get very close, leaving yourself open to attack after the shield evaporates.

Boomer Kuwanger
Weakness: Homing Torpedo Weapon Received: Boomerang Cutter

This is one of the easiest bosses in the game if you have the right weapon. Boomer Kuwanger's main attacks are to throw Boomerang Cutters at you and to try and charge at you. If you get too close, Kuwanger will also grab you with his horns and throw you into the ceiling. Equip the Homing Torpedo and continuously wall jump to defeat him easily; Boomer won't jump and the torpedoes will fly straight at him.

Sting Chameleon
Weakness: Boomerang Cutter Weapon Received: Chameleon Sting

Sting Chameleon is one of the trickier bosses to defeat, mainly because he uses so many different attacks. He will jump across the screen, hit you with his tongue, hang on the wall, throw Chameleon Sting at you, or hang from the ceiling (by his tongue) and make spikes fall from the ceiling. If you hit Sting Chameleon with a Boomerang Cutter, he will immediately stop whatever he's doing and jump to hang from the ceiling by his tongue and drop spikes. He is in a perfect position to be hit by another Boomerang Cutter while hanging, making the battle a simple process of jump, shoot and repeat.

Storm Eagle
Weakness: Chameleon Sting Weapon Received: Storm Tornado

Storm Eagle has very few moves that directly attack you; he is more likely to try and shove you off the edge of the platform. He will flap his wings to slightly push you towards the edge or he will fire Storm Tornadoes that do no damage but shove you backwards very forcefully; simply dash towards the middle of the platform to counter these attacks. He will also frequently dive bomb from the top of the screen to the bottom towards you but can easily be avoided by walking or dashing. His last attack involves launching an egg that explodes into four small birds that fly towards you, but they can be destroyed by shooting them. Chameleon Sting makes it easier to hit Storm Eagle, as it fires in three directions, but with careful timing it's just as easy to hit him with regular charged shots.

Flame Mammoth
Weakness: Storm Tornado Weapon Received: Fire Wave

Flame Mammoth's main attacks are to jump towards you, switch the direction that the conveyor belt moves, and shoot oil and fireballs at you. If a fireball hits an oil puddle it will create a Fire Wave that travels across the screen. By repeatedly wall jumping to the top of either wall, Flame Mammoth cannot hit you by jumping into you. When hit with Storm Tornado, Flame Mammoth will be momentarily stunned. Keep dodging and shooting and Flame Mammoth is easily beaten.
