Iron Knuckle

The Iron Knuckle is one of the toughest sub-bosses Link will have to defeat. It swings a mighty axe that deals devastating blows to whatever comes in its way. If Link is hit by this axe, he will lose quite a considerable amount of life energy. In Ocarina of Time, Iron Knuckles are associated with the Gerudo. In Majora's Mask, they are a part of the Ikana tribe.

To defeat an Iron Knuckle, you must run in, do a stab attack, and backflip quickly. The Knuckle will slash with the ax, and when he is done slashing, run in and get two more good attacks in. Repeat this process until he loses quite a bit of his armor. He will then become more frantic and begin charging at you much faster. Just step in and repeatedly stab him. Do not stop stabbing until he kneels to the floor and dies in a flood of purple flame.

The Iron Knuckles appeared in games such as Ocarina of Time and Majora's Mask. In The Adventure of Link, they are frequent enemies in the dungeons, and an Ironknuckle astride a floating horse appears as the boss of the third dungeon. A pair of them later appear in the sixth dungeon as sub-bosses. The easiest way to defeat Iron Knuckles is probably throwing bombs.

At their core, Iron Knuckles are exactly like Darknuts.
