|~ Principal Deedle holding Scooby-Doo hostage.|
Principal Deedle is the main antagonist of the 2009 film Scooby-Doo! The Mystery Begins. To steal a rare stamp, he impersonated the Dark Specter. He was portrayed by Shawn MacDonald.
His costume was a black cloak with a white mask. While's he not in disguise he wears a brown suit with a bow tie.
Deedle used the Dark Specter disguise to scare his students away while he searched for a rare stamp called the "Erie Stamp," which was a misprint, and that it was buried in a time capsule below his school with the help of two real ghosts named Prudence Prufrock and Ezekial Gallows.
However Fred Jones, Daphne Blake, Velma Dinkley and Shaggy Rogers were blamed for his plans and were suspended then later expelled from Coolsville High. With the help of Scooby-Doo, they later returned, cleared their names, rescued Vice Principal Grimes and defeated Deedle.
After his evil plan has been foiled, it was presumed he was fired from his job as the principal and sent to prison for his crimes. Then Vice Principal Grimes becomes the new principal and unexpells Fred and the gang, declares them as heroes for saving Coolsville High, and apologizes for accusing them.
