Witch Queen

The Witch Queen was the "Disguise" of Lady Azarni in the final level of Scooby-Doo! First Frights, who used to to terrify the baron's food festival and scare him and everyone else away from the castle. After a long battle against Shaggy and Scooby, the Witch Queen was defeated, however, Mystery Inc. didn't get the chance to unmask the monster as the castle collapsed soon after the fight. In the aftermath, the gang reveals they believe Lady Azarni was responsible, although the baron denies he knows her. As the game ends, the witch queen is seen flying away, implying it was a real monster.
