10. Dark Link (Ocarina of Time)
Although another memorable battle with Dark Link also appeared in Zelda II, the one in Ocarina of Time still stands out. Dark Link is technically a mini-boss, but he remains one of the best battles in the game. After stepping into an empty chamber in the Water Temple with only one small island in the middle, Link proceeds to the door on the other side only to see it locked.
Turning around, he comes face to face with his own shadow. This enemy can use the same sword slashes that Link can, and can be a tough customer to face head on. He can even jump on your sword, stopping you mid-slash as he disappears. Using items like the Megaton Hammer, Deku Nuts, or Biggoron Sword can help Link vanquish this shadowy foe.
