Metal-Heads are lone dungeon dwellers found in Stage 2 of Virtual Boy Wario Land. They are shorter than Wario and sport three viking-styled horns on their heads alongside hair that covers one of their eyes and donning ripped and thick pieces of cloth as coats.
Metal-Heads stay behind sealed wooden doors, waiting for Wario to approach their hiding spot. If he walks close enough, the Metal-Head will break through the door and begin to look around them before charging into Wario with a javelin. Wario can simply dodge the foes by jumping over them. If they hit Wario or he jumps on top of their heads, he will take damage.
