Maoh the Giant

Maoh the Giant (マオー・ザ・ジャイアント) is the boss of the Intro Stage of Mega Man X3. It is a huge Mechaniloid that was part of Dr. Doppler's army when they attacked the Maverick Hunter Headquarters. It attacks by punching with the large, spiked steel balls attached to its arms, crushing its enemies and building alike. Its only weak points are its head and arms. Unlike the intro stage boss in Mega Man X2, Gigantic Mechaniloid CF-0, touching Maoh's head or arms while they are in the background will not damage the player, and its attacks only inflict 1 unit of damage.
