Armos Knight

Link's Awakening
The Armos Knight is found in the Southern Face Shrine. Link encounters it during his search for the Face Key. The Knight can be defeated by shooting arrows at it with Link's Bow. This eventually destroys his armor leaving him vulnerable to either more arrows or Link's Sword. It is important to utilize the use of the Roc's Feather. When the knight goes to stomp the ground, Link can avoid being stunned by jumping before the knight hits the ground.

The Wind Waker
Another variant is found in The Wind Waker. Unlike past versions, Armos Knights are depicted as larger, more powerful versions of Armos Statues rather than actual knights. To defeat an Armos Statue, Link must wait until it charges up to him and after three jumps it will leave it's mouth open, then he throws a bomb inside its mouth. A quicker method to opening its mouth is shooting it in the eye, this also briefly stuns it.
