Ace Decade

Ace Decade is the nephew of the owner of a music studio.

The Scooby-Doo Show
Decade was smuggling records out of the studio in trash cans in order to sell them for personal profit. When a music writer, Tony Signs, realised his actions, Ace disguised himself as the "Disc Demon" and kidnapped Signs, locking him in a cupboard in the Cafeteria.

Decade attempted to mislead the gang whilst they attempted to solve the mystery, leading them to a tape recorder wired to the intercom in his office in order to give the appearance he was being framed. However, Signs left a clue which was his ultimate downfall; his last piece of music spelt the culprit's name in the first three bars: ACE DEC ADE. (The Diabolical Disc Demon)
