Dark Link is a mysterious entity that has appeared several times across the Legend of Zelda games, a dark or evil version of the Hero Link. Despite the fact that Dark Link’s appearances are often brief and nearly everything about him is shrouded in mystery, he has become a very well-known figure to Zelda fans. The latest game in the series, Tears of the Kingdom, even allows players to wear a Dark Link costume, further proving his popularity.
