Force Gem Knight
Force Gem Knights are enemies that appear in Four Swords Adventures.
Force Gem Knights are enemies that are disguised as Force Gems. When Link gets near, they start to attack him. If Link doesn't defeat them quickly enough, they explode and leave behind a single Force Gem. They are great swordsmen as well; Link can't attack them from the front, he must do so from the sides or the back. If Link lands three hits quickly enough, they leave behind a big green Force Gem.
