Dragon Ball has always relied on its villains to make for memorable moments. Each arc is only as good as its presiding baddie and the challenge that they present the Z Fighters with. Though fearsome foes like Demon King Piccolo, Frieza, Cell, and Buu are what kept the main series so engaging, plenty of non-cannon foes have been introduced over the years in various Dragon Ball films. None of them have enjoyed the popularity and staying power that Broly has.
