2002 FilmThe Demons were an ancient race of creatures that appear as supporting antagonists in the 2002 Scooby-Doo film. They inhabited the island that would become the theme park Spooky Island. They came under the control of Scrappy-Doo who in turn impersonated Emile Mondavarious through the Daemon Ritus, who sought to use the creatures to get revenge on Mystery Incorporated and conquer the world. The Demons disintegrated when exposed to sunlight, and thus used human bodies for protection.
The Demons once populated the very isle which would become Spooky Island hundreds of years later.
Corrupted by the power of a pyramid-shaped artifact known as the Daemon Ritus, Scrappy-Doo took control of the Demons to complete their ancient ceremony and to conquer the world. He created a mechanical version of Spooky Island's creator and owner, and arranged for Mystery Inc. to be brought there. However, Mystery Inc. discovered the Demons' weakness, that the demons could be killed with sunlight and used a skeleton head disco ball to reflect sunlight, destroying the Demons. Scrappy was defeated shortly after.
Witch QueenThe Witch Queen made her debut in Scooby-Doo! First Frights. While her real identity is Lady Azarni, the Witch Queen is a real ghost (and a demon). She is tall, with creepy yellow pupils, black eyes, and a purple cloak. Everything else is black clothing, armour, and horns (or a crown). She is evil, mean, and heartless. She used the disguise of Lady Azerni to terrify the baron's food festival and scare him and everyone else away from the castle. After a long battle against Shaggy Rogers and Scooby-Doo, 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 revealed they believed Lady Azarni was responsible, since all the clues point to her. Although the baron denied he knew her. By the end, the Witch Queen was flew away, implying it was a real monster. It is unknown what happened to her after this.
The Evil Entity was an evil Anunnaki that was imprisoned within a crystal sarcophagus, buried beneath Crystal Cove. In its original form, the Evil Entity looked like a floating mass of dark green tentacles, with two glowing eyes. After consuming Professor Pericles, the Entity looked like a giant parrot head with horns and squid-like tentacles. It is genocidal and dangerous, as all it vares about is complete destruction of universe.
This is a brief treatment of Evil Entity. For detailed information see The Evil Entity.
