Amelia von Butch

Dr. Amelia von Butch is the main antagonist of Scooby-Doo? In Where's My Mummy? She is an archaeologist and world-class treasure hunter. Her henchmen are Campbell and Natasha, among others.

Role In The Movie
She encountered Mystery Inc. when she decided to go after the crown of Cleopatra, hidden within the Sphinx. Thus, she and her crew ran right into Velma Dinkley's Ghost of Cleopatra plan to protect the treasure. After avoiding the "army of the undead" and watching her henchmen seemingly be turned to stone, she finally reached the crown. In grabbing it, however, she set off a trap, flooding the tunnels. Amelia made it out of the Sphinx only to be caught in a carpet and have the crown snatched by Triple A's hawk.

Trivia
Von Butch is one of the few examples of Scooby-Doo villains who don't wear monster costumes.
