Vile, known as Vava (ヴァヴァ, Vava?) in Japan, is a recurring major antagonist in the Mega Man X series of action platformer games. He first appeared in the original Mega Man X and frequently reappears as a mid-game boss in later games. Next to Sigma, Vile may be the Mega Man X series' most known boss antagonist.
He has a distinctive helmet with a T-shaped visor.
Vile was originally an A-Class Maverick Hunter, though during his career he racked up more disciplinary charges for unnecessary force, excessive violence and endangering his team-mates than any other Hunter in history. It even hit the point where other Hunters were afraid of being put on a mission with him, due to his recklessness and downright bloodthirsty tactics. When Sigma turned Maverick and took many of the best Hunters with him on his war against humanity, it was no surprise that Vile followed him willingly. Though his favorite tool in battle was Ride Armors, even on his own he was a powerful Hunter.
He was thought to have been destroyed by Zero and X during the first Sigma Revolt. Zero sacrificed himself to destroy Vile's Ride Armor, and X defeated him in single combat. Ultimately, both Reploids' remains were recovered from the wreckage of Sigma's base and rebuilt by Maverick agents.
Vile was not heard of again until the riots of DopplerTown a few short years later. Under the control of Sigma, the benevolent Dr. Doppler rebuilt Vile into a more powerful form. Vile's sole drive then was the destruction of X and Zero, rushing into combat. Even backed by his new, high-powered Ride Armor "Goliath", Vile fell again to X. Unfortunately, recovery teams sent into DopplerTown after the riots were unable to locate Vile's remains.
Vile was once again re-activated to serve as a lackey and coup-out for Sigma's (and indirectly Lumine's) plan. In this iteration, he was upgraded once again, donning a new design and more powerful weaponry. He engaged X, Zero, and Axl on several occasions, each time losing until his final defeat. However, he is not seen getting destroyed in the game's "Hard Mode", which contains the full ending.
