While the world eagerly awaits the second season of Netflix’s One Piece live-action, few know that 35 years ago, another animated series laid the foundation for pirate stories with an unprecedented budget. That series is The Pirates of Dark Water, a Hanna-Barbera masterpiece still longing for a proper conclusion.
The predecessor to Luffy and an unfinished treasure hunt

Before Monkey D. Luffy set sail to become the Pirate King, audiences around the world were captivated by Ren’s adventure in The Pirates of Dark Water, which premiered in 1991. The story follows Ren and a crew of outcasts aboard a ship as they try to stop the “Dark Water,” a mysterious black substance threatening to consume their world.
To save humanity, Ren must gather the “Thirteen Treasures of Rule” while facing supernatural dangers and the ruthless Captain Bloth. Although the series ran for two seasons, Ren’s journey never received a proper ending, leaving a significant void for fans for over three decades.
A high-budget Hanna-Barbera animated gem

The Pirates of Dark Water became a hit thanks to its sharp animation and groundbreaking storytelling that surpassed other Saturday morning cartoons of its time.
It wasn’t just an ordinary cartoon but a major investment for Hanna-Barbera, costing up to half a million dollars per episode in 1991.
This hefty budget showed in the advanced animation techniques, featuring up to 12,000 frames per episode, double the usual amount for series back then. Beyond the stunning visuals, the show impressed with a darker, more mature storyline centered on Ren’s quest, setting it apart from typical children’s entertainment.
Despite the high investment, the series didn’t meet financial expectations, causing plans for a third season or sequels to be permanently shelved.
Why now is the perfect time to revive this legend
Today, pirate-themed media is enjoying a golden age, fueled by the success of One Piece on Netflix and Crunchyroll. This makes it the perfect moment to bring Ren and the ship Wraith back to life.
History shows that reviving classic animated franchises can lead to great success, as seen with Avatar: The Last Airbender and King of the Hill. The Pirates of Dark Water offers a rich, unexplored ocean world full of potential that wasn’t fully tapped in its brief two-season run. Although it struggled commercially, the series still has its own comic and video game ecosystems, proving its lasting appeal.
