Lord Infernacus is a blazing skull like ghost villain that appears only in Scooby's dream. He kidnapped the mystery solvers at the school and threatened the sidekicks not to leave the building or call for help so that he can shipped the hostages to Africa. But it all backfired when Scooby-Doo got suspicious over a genie pig. Infernacus is voiced by Avenger voice actor Rick D. Wasserman.
