|Vehicles and/or Gadgets||Giant Scarab|
The Mummy is an undead warrior who captured the Scooby Gang (Fred, Daphne and Velma) inside of the Haunted House to prevent them from interfering with his search for the final Foundation Element the Diamond Scarab. During his search, he is met up with Batman, Gandalf and Wyldstyle whom he tries trapping to prevent them from obtaining the Scarab. Soon after, the Trio find the Diamond Scarab which is then taken by the Mummy who sends them through the floor and into a cave below. After escaping the cave, the Trio stumble upon an abandoned mine shaft chasing after the Mummy. After the chase ends, they then enter the Fairground where the Mummy battles them by using magical powers given to him via the Diamond Scarab to summon in his army of undead Mummy Warriors, Anubis Guards and even his Giant Scarab. After he is defeated, Gandalf retrieves the Diamond Scarab as Batman unmasks the Mummy to what he assumes is the Fun Fair Owner but to only find out that he is really Lord Vortech in disguise. Lord Vortech then removes from his suit and exclaims that he "would've gotten away with it if it weren't for you meddling kids." The Trio then goes through a rift opened by Vortech just as Shaggy and Scooby-Doo come to find the Mummy's costume and take credit for stopping him.
