He can jump pretty high, shoot a flurry of small shots, and a wave of fire that travels across the floor. This battle is similar to the one in the first Mega Man X game. Wall jump over him, land, turn and unleash a charged shot or one of his weaknesses, then jump on the next wall and repeat. He just dashes left and right, hitting the walls. Vile's Ride Armor is a variation on the Kangaroo Ride Armor. Doing this will give you an alternate version of a later stage, along with different boss fights and the opportunity to get a very powerful weapon that will make the terrible final boss much more bearable. Like the Nightmare Police, you'll have to deal the final blow with a weapon he's weak to in order to completely destroy him. Both are weak to Ray Splasher and Spinning Blade, but you might run out of ammo if you only use one of them.

Once in his Ride Armor and once without it. Take out the Hamma Hamma with a Triad Thunder, then head up the ladder and into the door. Getting out of the elevator is inadvisable because it leaves you vulnerable to debris. This will bring you up past several life pickups. Otherwise, you'll have to wall jump up, avoiding the debris. If you defeated Volt Catfish before coming here, the elevator will move.

Start by going right and taking out the Notor Bangers, then head down and fight the Wall Cancers. Vile has his own stage! Reach it by finding one of the teleporters in Blizzard Buffalo, Volt Catfish, or Crush Crayfish's stages.
