Lord Darkar (simply known as Darkar) is an antagonist in the Winx Club series, and the main antagonist in the season 2. He has also been called the Prince of Darkness by Miss Faragonda, but it is unknown whether he is the same Prince of Darkness mentioned by Darcy, when she first sees Riven and says that he has a level of negative energy equal to the Prince of Darkness. He only appears in Season 2, but makes a few cameo appearances in season 3 and 4 (though only by name, flashback, and picture), and the season 5 trailer.
