Dark Link

Dark Link (Dāku Rinku) is a recurring antagonist in the The Legend of Zelda series. This shadowy duplicate of Link is able to utilize many of Link's own attacks, often mimicking him. It is unknown if any of Dark Link's appearances across games represent the same entity, or if each game features it's own unique Dark Link. It is also never revealed whether he serves some master, or fights of his own accord. Multiple Dark Links occasionally appear together; it is unclear if each of these possesses an individual consciousness, or if they are all just aspects of the same being.
