Vile (VAVA in Japanese) is a recurring major villain in the Mega Man X series, and frequently reappears as a mid-game boss. He has a distinctive helmet with a T-shaped visor, similar to that of Boba Fett. Vile is introduced in Mega Man X, where he is a former Maverick Hunter now serving Sigma as his right-hand man. When he first fights X (while in his ride armor) in Mega Man X, Vile reveals the fact that he is stronger and more powerful than X and his "antiquated weapons". He and X fought, and X was almost defeated, but Zero came to his rescue by blasting the arm from Vile's ride armor. Vile escapes and vows to confront X and Zero later. When Zero later tells X that he has found Sigma's fortress, they split up. Zero and Vile meet at the fortress entrance just as X arrives. They battle (with Vile in his repaired ride armor), and by the time X confronts Vile, he has captured Zero. X is then again nearly defeated by Vile. Zero once again comes to the rescue, as he regains strength, jumps on Vile's back, and destroys Vile's ride armor. The resulting explosion also destroyed Zero's legs, fatally damaging him. With Vile's ride armor destroyed, X defeats Vile, enraged, and continues on into Sigma's fortress. Zero gives X his arm cannon before he dies (only if the player did not obtain arm cannon upgrade hidden in the game).
