Armos Knights

Armos Knights are the bosses of the Eastern Palace, the first dungeon in the game. They consist of six blue statues that, despite being armed with swords and shield, only hop around in predefined patterns. To damage them, Link must shoot them with his Bow, and after enough hits, the knight dies. Once five are killed, the remaining knight turns red and begins hopping aggressively, attempting to land on Link. When the final Knight is defeated, Link earns a Heart Container and the Pendant of Courage.

Armos Knights re-appear in Ganon's Tower in the Dark World. Aside from the floor being made of ice, the battle is exactly the same as the first encounter.
