Scooby-Doo (DC Comics)
His business didn't do well after he took the advice of his cook and tried to sell "pizza in a cup" instead of regular pizza. The cook also sabotaged the cups so they spilled ingredients on people. After the villain was captured, Voltaire decided to return to selling regular pizzas.
- He has a sterotypical Italian accent.
