Iron Knuckle
From Zelda Wiki, the Zelda encyclopedia
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.
To defeat an Iron Knuckle, you must wait until it swings and gets its axe stuck in the ground, then either do a jump attack or slash as many times as you can, and then back flip. As the Iron Knuckle's armor comes of, it will get faster.
