19. Fantastic Four (1967-1968, Fox)
It might not have had the best animation, or even logical plots, but Hanna-Barbera’s interpretation of the Fantastic Four was one of the best superhero cartoons of its time. Complete with classic villains and storylines borrowed from the actual comic books, the Four’s small screen debut still stands as the best versions of the team outside of the comic world. Fox spent $200 million on two blockbuster movies based on Marvel’s First Family and they couldn’t come close to achieving what this show did on a shoestring budget.
It might not look so great by today's standards, but this is the show that introduced countless kids around the world to an upstart company called Marvel. Without a proper DVD release or consistent reruns, though, Fantastic Four has unfortunately been lost to a younger generation.
