Vile

Vile, or VAVA (ヴァヴァ, Vava) in the Japanese version, is a character of the Mega Man X series. He used to be a Maverick Hunter prior to the first X game and was ranked SA-class and was a member of Sigma's 17th Elite Unit prior to his commander's rebellion against humanity. He appeared in multiple games of the series as a boss character and was being playable for the first time in Maverick Hunter X, a remake of the first Mega Man X for the PlayStation Portable.

Personality
Vile is a very arrogant, violent and rude character. Though he used to be a member of the Maverick Hunters, he didn't accept orders from anybody except himself which often resulted in fierce arguments with his commander and (eventually) to his own arrest and labeling of being a Maverick.

Because of an inrepairable shortcut in his electronic brain, Vile developed a strange passion for hunting down Mavericks and totally annihilating them and causing as much damage as possible on the territory. This also includes innocent bystanders and comrades alike.

In all incarnations of the character, Vile holds a deep grudge against X and looks down on him because for him, X is a weak character and doesn't deserve that much attention.

The Day of Σ
Shortly before Sigma declared war on humanity, Vile was arrested by the Hunters for unknown reasons, however Zero claimed that he "must have caused a ruckus again". It is presumable that he again disobeyed orders from superior officers and/or threatend the safety of comrades and bystanders while hunting Mavericks. During the chaotic search for the perpetrator who hacked the Hunters' database (which was actually Sigma himself) and the defense of Abel City from another berserk Mechaniloid, Vile was freed by his former commander who requested his assistance in defeating X, saying that he needed a Reploid that could go Maverick on his own accord. Eventually, Sigma left Vile alone, freed of his chains and open to his arsenal, so he could decide whether or not to join his rebellion.

Mega Man X / Maverick Hunter X
In the original Mega Man X, Vile's character wasn't that expanded and deep yet. He was pictured as nothing more than Sigma's loyal soldier and bodyguard who led his attack teams against the humans. While infiltrating Sigma's fortress, Vile rushed to the scene to stop the intruders, which happend to be X and Zero. While Zero chased after him, X was left behind for a moment. During this time, Vile had jumped aboard his new Ride Armor and had imprisoned Zero in a cage and used him to blackmail X to surrender. X fought him however, up to a point until he was (again) cought by Vile's stun net. In order to save his friend, Zero mobilized all of his power to break free and destroyed the Ride Armor by firing a charge shot from point-blank range. He was then destroyed in a one-to-one battle by X.

In Maverick Hunter X, Vile's persona was greatly expanded as a rogue character with a strong hatred for X and a desire for destruction. Though he joined Sigma's rebellion and helped attacking the Central Highway onboard Storm Eagle's Death Rogumer, he hardly followed any orders and did what he could best. Causing havoc and fighting X. At first it seemed X was able to defeat him, but was captured between the iron fingers of Vile's Ride Armor, stating that he'll destroy him and eventually defeat Sigma as well to change the world. X was then rescued by Zero and Vile retreated. He then showed up in Sigma's fortress, having already defeated Zero like in the original game and laid him in a hallway as a bait for X, whom he captured. However, he had underestimated Zero who was able to stand up and destroy the Ride Armor, like in the orignal Mega Man X. After a long battle, he was regretfully destroyed by X.

Maverick Hunter X' Vile Mode, an unlockable bonus mode, however took a different path. Instead of joining Sigma's rebellion, Vile decided to prove to Sigma that he was better and more powerful than X. After fighting X on the Central Highway, he decided to battle against Sigma's followers to gain more power and reputation. Though all of the eight main Mavericks were rather friendly to him (and offered him to leave), he destroyed all of them and absorbed their powers in order to create new weapons. Ultimately, he infiltrated Sigma's fortress and fought his way through it until he was cornered by X and Zero. Both of them battled him a the same time, yet were defeated by him.

After defeating both of them, Vile admited that X, whom he hated than no one else, had grown stronger, but was still a whimp to the very end and never had the power to change the world. He was then attacked by a weakend Zero grounded him before he was hit by a charge shot of X. When he awakened, he was accompanied by Sigma. Heavily damaged, he asked what was so important about X. Yet, instead of aswering however, he asked him why he did all this and whether he wanted to stand before him as a Maverick Hunter or kneeling before him at his mercy. Upon this question, Vile wasn't unable to comply and started laughing, stating that he wasn't actually sure about it. He was then left by Sigma. As he walked away, Vile stated that by fighting X, he proved the right of his existance, that HE is Vile. When he tried to hold Sigma from leaving however, his functions seized and he was left frozen in his desperate position.

Mega Man Xtreme
Vile made a small appearance in the opening stage of the game. Said level is a digitalized version of the Central Highway stage from the original Mega Man X. He serves as the boss of this stage and is again seen riding his Ride Armor. However, this version of Vile is not the actual one but merely a data record of the character that had been stored in the archives of the Maverick Hunters' Mother Computer In this game, he is errorously refered to as "VAVA", which is actually his original Japanese name. He was destroyed/deleted by X.

Mega Man X3
What was left of Vile after his destruction at the hands of X in the first game was salvaged from a Reploid scientist named Dr. Doppler, who was infected with the Sigma Virus and controlled by Sigma himself. Doppler created a new body for him and upgraded his weapons to be more powerful. However, the influence of the Sigma Virus around him turned him insane and the only thing he could think of was to get revenge of X who had previously killed him. Instead of assisting Doppler in creating a new body for Sigma, he left Doppler's lab on his own accord. He lured X into an abandoned factory which was set up to self-destruct and tried to hinder X from escaping by fighting him in his new Rider Armor.

In case X didn't use the Ray Splasher, Vile's weakness, on him, he would flee the scene. He would then reappear at Doppler's lab as one of the final bosses, his armor kit painted more greenish and riding an upgraded version of his Goliath Ride Armor. Eventually, he was destroyed by X, but not before swearing to haunt X until the day he died.

Arsenal
Main article: Vile's weaponry

Vile is notorious for using a varity of weapons, hidden within his body. His most significant weapon however, is his trademark shoulder cannon, the Front Runner.

In the Maverick Hunter X remake, Vile is able to acquire more than 50 different weapons, divided into three main categories (shoulder mounted weapons, hand mounted weapons and leg mounted weapons) and each of them is again divided into three subcategories. These weapons vary from standard laser blasters, projectile weapons to grenade launchers and flamethrowers. His default weapons in Maverick Hunter X are the Front Runner, an energy based cannon on his shoulder which can be fired in three directions, a vulcan machinegun with limited range at his fingertips and a grenade launcher mounted into his knees.

Trivia

 * It's a common tale amongst the Mega Man community that the character's name was changed from VAVA to Vile for the North American release of Mega Man X because Capcom was afraid of being sued by LucasFilm because of the character's resemblence to Boba Fett, a character from the Star Wars universe. This was due to Vile's resemblence to Boba Fett's mandalorian helmet (T-visor) and because his Japanese name can also be spelled "BABA" (the letters B and V are spelled and written the same way in Japanese).
 * Vile makes a small cameo appearance in Mega Man Zero 2 as one of for "haunting spirits" that attack Zero if he is grabbed by Phoenix Magnion.
 * Vile appeared in Mega X, the 26th episode of the Ruby Spears Mega Man cartoon. He came from the future along with Spark Mandrill to steal Lightanium from Dr. Light's newly opened Plasma Power Plant to finance Sigma's war against humanity. He was voiced by Lee Tockar.
