The One Piece world hasn’t stopped buzzing about Marshall D. Teach — aka Blackbeard — and what his next destination might be after the Wano and Egghead arcs.

With the Straw Hat Pirates sailing toward Elbaph, fans are theorizing whether the Blackbeard Pirates could set their course for Fish-Man Island next. Let’s break down the most compelling theories, clues, and possibilities shaping this hot topic.
Why Fans Think Fish-Man Island Is on Blackbeard’s Radar
Blackbeard has been the embodiment of ambition in One Piece, always a step ahead and rarely predictable. After his moves in Wano and encounters with the Heart Pirates, Blackbeard’s agenda remains unclear — but his hunger for power certainly doesn’t.
A few fan theories suggest a connection between Blackbeard’s actions and Fish-Man Island:
Caribou’s connections: The swamp-man Caribou has appeared near Fish-Man Island in the past and later linked up with Blackbeard’s crew, leading fans to think Blackbeard may learn something crucial through him.

Road Poneglyphs & Ancient Weapons: Blackbeard is known to be hunting powerful items — like Road Poneglyphs and possibly one of the Ancient Weapons. While Pluton might be his primary target, unlocking clues tied to other legendary locations could lead him closer to Fish-Man Island or nearby seas.
Strategic choke point: Fish-Man Island sits at the entrance to the New World. Controlling it could give the Blackbeard Pirates a strategic advantage in intercepting other crews, supplies, or secrets — including the One Piece itself.
It’s important to note that not all theory crafters agree Blackbeard’s next big move will be toward Fish-Man Island. Some argue his current priorities could lie elsewhere — such as clashing with the World Government in Mariejois or chasing plunder tied to the Ancient Weapons.
What Does This Mean for the Straw Hats in Elbaph?
As the Straw Hats journey toward Elbaph, the storylines are splitting into parallel races:
Luffy’s crew is following the final Road Poneglyphs on their path to Laugh Tale.

Blackbeard’s crew may be racing to intercept or steal such Poneglyphs or other secrets.
If Blackbeard does detour to Fish-Man Island, it could set up one of the most explosive encounters in the One Piece finale — especially considering the deep history and emotional ties the Straw Hats have with the island and its people.
