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

Launch Octopus
Weakness: Rolling Shield Weapon Received: Homing Torpedo

Boomer Kuwanger
Weakness: Homing Torpedo Weapon Received: Boomerang Cutter

Sting Chameleon
Weakness: Boomerang Cutter Weapon Received: Chameleon Sting

Storm Eagle
Weakness: Chameleon Sting Weapon Received: Storm Tornado

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.
