Kao ga Mehda

Kao ga Mehda (カオ・ガ・メーダ) is a giant hammer robot enemy from Mega Man 8 that is native to Sword Man's stage. It is in the background, thus it is invincible. Kao ga Mehda attacks by slamming a pillar into the lava. It mainly appears in the lava flow section of Sword Man's stage, but one Kao ga Mehda that pursues Mega Man appears in the battle against Gearna Eye.

Trivia

 * Its name is derived from the Japanese phrase "kao ga me da", which means "its face is an eye".
 * Mega Man 5 has an unused enemy that is similar to this robot.
