This one gut-punches you in the first act and then makes you live with it. Kid grows up barefoot on a Caribbean island with animals for company, and the entire warm little world gets pulled out from under him when his dying foster father admits the truth: his blood father is Captain Morgan, the man who ruled the seven seas. Then the show does the cruel thing and kills the reunion before it happens. What's left is a boy chasing a dead legend across water while every other pirate alive circles the empty throne, which turns the whole run into a question about whether a title is something you inherit or something you have to take. It's 1966, 31 episodes, black and white, and the sea animation carries more weight than it has any right to. Watch it for the deathbed scene that starts everything.

Kid grows up on a small island drifting in the Caribbean, living happily with a host of animals for company. That calm ends when his dying foster father tells him the truth: his real father is Captain Morgan, the pirate who rules the seven seas. Kid sets out to find him, only to learn that Morgan has died. Other pirates now crave the title of ruler, including the notorious Tiger Hook. To defend the seas, Kid becomes the pirate king of his father's ship in this 1960s adventure series.
