Dragon Ball is one of the most popular anime of all-time and one of the reasons that it’s become such an evergreen staple of the industry is because of its passionate protagonist, Goku. Audiences have watched Goku mature from a curious boy to a courageous adult over Dragon Ball’s multi-decade run. Goku’s adventures never get old, especially when he has so many complex villains to defeat, whether it’s Demon King Piccolo, Frieza, or Majin Buu.
