Doomknocker

are recurring NaN Enemies in. NaN Doomknockers go unnamed in.

Doomknockers are blue-armored, bull-like soldiers, similar in appearance to the Iron Knuckle, that attack by throwing spiked clubs horizontally towards Link. Unusually, these clubs will act like Boomerangs, and fly back towards the Doomknocker after being thrown. These attacks cannot be blocked with Link's shield unless he uses the Reflect magic, so the best technique to destroy a Doomknocker is to use the Down Thrust technique after dodging their projectiles with jumps. They command the NaN Parutamus.

A Doomknocker-like enemy appears in, during the episode entitled Quest for the Potion of Power. While searching for the Potion of Power, Kevin, Link, Princess Zelda and Game Boy reach the Island Palace and begin to explore. Coming across a huge door, Game Boy accidentally opens it without realizing that a huge and seemingly mechanical knight lay behind it. This giant bolt-covered guardian swings its club at Game Boy but misses, causing it instead to smash a nearby statue. Thinking fast, Kevin shoots the switch above the doorway to cause it to close before the Doomknocker can get past, trapping it behind the door.
