Mega Man X (character)/Maverick Hunter X

Mega Man X is the main character protagonist of Mega Man Maverick Hunter X. He is Maverick Hunter from the 17th unit, and is the last creation of Dr. Light.

The Day of Σ
While X was a member of Sigma's Elite Hunter Unit 17, he befriended many other members of this unit, particularly the S-A class hunter Zero. The Hunters were busy though, as giant Mechaniloids (robots less intelligent than Reploids, usually for simpler tasks and manual labor) began attacking Abel City. The Maverick Hunters were baffled as to who was behind the attacks. During one of the battles against the berserk Mechaniloid, Sigma saw X hesitate to take his shot to stop the rampaging Mechaniloid, because an ally Hunter was in the way. Sigma then rushed in and did the job for the hesitant X by using his saber on the rampaging Mechaniloid. The attack stopped the Mechaniloid and saved the Hunter from its grasp. Though Sigma's intervention is what saved the Hunter, it came at the cost of the Hunter's arm. Sigma would later lecture X about the importance of acting when he has the chance, and that hesitation may cost lives. After speaking to Dr. Cain, Sigma discovered that X's worrying is what makes him so advanced. It was then that Sigma became obsessed with X and learning more about him.

X and Zero began investigating these events to discover the hacker causing Mechaniloid outbreaks throughout Abel City. The two hunters traced the signal being sent to the Maverick Mechailoids to a missile facility, where they discovered that the hacker responsible for the rampaging Mavericks was none other than Sigma, who then proceeded to launch all the missiles stored at the facility to Abel City. X and Zero fought Sigma, but were damaged in the encounter, allowing Sigma to escape, although not before X, with some of his limitless potential awakened, burned Sigma's characteristic scars onto his eyes. Sigma eventually turned his lieutenants Maverick, and launched an attack against Abel City, leading into the events of Maverick Hunter X.

Mega Man Maverick Hunter X
It starts with X who is dealing with Maverick activity along the Central Highway, part of Abel City. As he goes about fighting off hordes of Mechaniloids, he meets Vile, who has apparently gone Maverick, and confronts X in his special Ride Armor.

X upon encountering Vile accuses the latter of being involved in Sigma's revolt, only to learn to his horror that Vile didn't actually care about the revolt and just wanted an excuse to cause trouble for X due to his hatred of him. X briefly manages to subdue Vile's ride armor, only for him to be captured due to letting his guard down, causing Vile to berate him for underestimating him before making clear he intends to eliminate both him and Sigma so he can change the world on his own terms. However Zero interferes and after some tense words between Zero and Vile, the latter retreats, with Zero and X discussing Vile's sudden change in allegiance before X is told to go back to Hunter Base to rest up, vowing to catch up later. X then does so, although not before making sure to thank Zero for saving him again.

X then faces the eight 'leaders' of Sigma's Maverick armies. One by one, he battles them, defeats them, and obtains their special weapons.

Once the eight bosses are destroyed, X is informed that Zero has finally discovered the whereabouts of Sigma's fortress.* They discuss their method of assault. Zero tells X he will barge in the front to draw the enemy's attention, and suggests X find another, safer way in. During his journey throughout Sigma's Fortress, X confronts the eight bosses yet again and, as before, he defeats them to move onward.

In the third section of the fortress, X reaches a small hallway where he sees that Vile has successfully defeated Zero, and must battle the war-machine once more to rescue him. At first, he is once again overwhelmed by Vile's powerful Ride Armor,* but it is at this point where Zero gets his second wind, leaps on the machine from behind, and destroys the ride armor in a desperate attack.* This utterly destroys the Ride Armor, although leaving Vile unharmed. Still, X can now battle on more equal ground with Vile, and defeats him after a tenuous battle. He then rushes to Zero, who is in such critical condition that he urges X to leave him behind, and fight Sigma in his stead. With much regret, X marches onward to fight Sigma.

X finally reaches the boss chamber where Sigma resides. They have a brief exchange, and Sigma congratulates him for "making it this far", but then comments that he will put X to a little test before engaging the Hunter himself. X is then forced to fight Sigma's dog, Velguarder. After destroying the guard dog, Sigma throws off his cloak and fights X head-on with his beam saber. X eventually defeats Sigma, but as his body exploded, Sigma's head attaches itself to a much larger body, which lights up and reveals a menacing wolf themed battle-body that attacks X, nearly taking up the entire room. X fights Sigma and defeats him again, causing the fortress to collapse. X manages to get out in time and watches the fortress collapse as he contemplated his actions, and his future.
 * According to the Rockman X Saikyou Daizokan, this massive body is an incomplete reploid unto itself, which Sigma then assumes control over: "A yet incomplete extra large wolf type repliroid. Sigma's head takes over the functions of the brain, but because of its excessive size, the feet and arms require more development time to be completed. Once the super-powered repliroid is completed, Sigma will be unstoppable in his plan for world domination!"
