Jack Rabble

Jack Rabble sold robot models at conventions, sharing a booth with Owen Garrison.

Physical appearance
He has dark hair with white sideburns. He is on the heavy side.

Personality
He appeared to be friendly and to like Owen, but he was actually a cunning schemer.

Scooby-Doo! Mask of the Blue Falcon
He created robots of bats, a Hideous Hyde Hound, and a Giant Mr. Hyde and attacked the comic convention at the Hotel San De Pedro as Mr. Hyde. His goal was to divert an armored car containing convention receipts so he could rob it.

Appearances

 * DTV19. Scooby-Doo! Mask of the Blue Falcon

Notes/trivia

 * He framed Owen, but apparently that was just a diversion (after the armored car robbery it would be clear that there was a second Mr. Hyde).
