Metonger Z

Metonger Z (メットンガーＺ) is the boss from the third stage of Mr. X's Castle in Mega Man 6, a robot tank controlled by a Metall. Except for the cockpit, the tank's armor is made of a super alloy that can repel any attack. The weak spot is the cockpit, and it takes more damage from Blizzard Attack. Its attack alternates between straight shots and bouncing bullets.
