Vile MK-II, known as VAVA MK-II in Japan, is an upgrade of Vile's body made by Dr. Doppler in Mega Man X3. While more powerful, the only thing Vile could think of was to get revenge on X, who had previously defeated him. Instead of assisting Doppler, he left to follow his own agenda. Vile MK-II usually appears as the boss Doppler Stage B, but he can be fought earlier as an optional secret boss in his own stage, which can be accessed from the stages of Blizzard Buffalo, Crush Crawfish, and Volt Catfish. In both appearances Vile starts with a Ride Armor. In Vile's stage he uses the Ride Armor type DRA-00 (Kangaroo), while in Doppler Stage B he uses the Ride Armor Goliath (Brown Bear in Japan).
