Armos Warrior

The Armos Warrior (ムジューン, Mujuun) is a breed of Armos that lurks in Skull Dungeon waiting to stop any intruders that dare cross its path in Oracle of Ages. It boasts a huge shield that protects it from any damage from the intruder, and a sword that it directs seemingly telepathically. Link managed to destroy the monsters shield by going behind the beast before it could change the direction of its sword. After the shield was destroyed, Link used the same trick to slay the monster.

Trivia
The Armos Warrior is similar in appearance to the Armos Knights from A Link to the Past and Link's Awakening.
