Armos Knights

The Armos Knights (デグアモス, Degu Amos) guard the Pendant of Courage within the Eastern Palace, the first dungeon of A Link to the Past. They can be defeated by sword slashes (about five for each Knight) or by arrows (three for one knight). They fight by jumping around in formations. Once their numbers are diminished, the last one will turn red and follow Link, attempting to crush him with hard stomps around the room. As with the others before, three arrows will finish him off. After emerging victorious, Link is rewarded with the Pendant of Courage and a Heart Container.

Later in the game, they show up once more in Ganon's Tower. They must be defeated one more time to advance to the top of the tower, where Agahnim awaits. They are defeated in the same manner as before, but Silver Arrows and the Master Sword allow for a much quicker fight. The battle does, however, take place on a slick ice floor, making attacking a little more troublesome.
