Doomknocker

A Doomknocker (ヘルグーマ, Hell Guuma) is a blue-armored soldier, first encountered by Link in Parapa Palace in Zelda II: The Adventure of Link. They are similar in appearance to the Iron Knuckle, and attack by throwing maces horizontally towards Link. The best technique to destroy a Doomknocker is to use the Down Thrust technique after dodging their projectiles.
