Gearna Eye

Gearna Eye (ギアーナ・アイ) is the mini-boss in Sword Man's stage in Mega Man 8. Its weakness is the pinkish gem when its face is open, but it also shoots flames from there. Also, when it is near defeat, it summons a hammer (Kao ga Mehda) that smashes the bridge, leaving the platforms for Mega Man to walk on. Sometimes it calls Kao ga Mehda to hit where Mega Man last stood. Try the Flash Bomb's from Grenade Man on it.
