One Piece theory explains why Joy Boy had to apologize to the entire Fish-Man island.

The first pirate in the history of One Piece, Joy Boy, is the most mysterious character in the entire series, and his narrative has a lot of unanswered questions that the fans have been trying to figure out since the beginning. From the One Piece treasure to his connection to Will of D, Joy Boy is the central link to all these mysteries.

However, one of the biggest mysteries about Joy Boy is his connection to Fish-Man Island. During the Fish-Man island arc, it was revealed that the poneglyph that is kept there has an apology from the mystery character that is embedded on the stone, but no one knows the reason behind it. The only information about the apology is that it is somehow connected to Noah, the enormous ship, and a promise.

On the other hand, there is a theory that suggests Joy Boy’s apologized to the entire Fish-Man Island because he might be the reason behind the brutality that the people of the island have suffered for the longest time.

Joy Boy’s Connection to Fish-Man Island

When the Straw Hat Pirates in One Piece resume their journey after the time skip, the first island they reach is underwater, and it is called Fish-Man Island. The island served as an underwater gateway to the New World, and because of this, a lot of pirates traveled there and caused havoc until Luffy decided to call it his own territory.

When the Straw Hat Pirates were at Fish-Man Island, they came across a poneglyph, which was later revealed to be an apology from Joy Boy himself. In the apology, Joy Boy mentioned that he failed to fulfill a promise that he made to the people of Fish-Man Island involving the huge ship Noah, which was also created during the Void Century.

The apology also mentioned the Ancient Weapon Poseidon and its ability to talk to the Sea Kings. However, no one knew about the content of the Poneglyph and the apology that Joy Boy made towards Fish-Man Island. Also, he mentioned that someone else might come and fulfill his promise and complete the deal with Fish-Man Island.

The Reason Behind Joy Boy’s Apology Explained

According to the theory, Joy Boy’s apology may be the result of the Fish-Man taking part in the war that took place during the Void Century. The theory states that in order to fight twenty nations of the World Nobles, Joy Boy might have formed an alliance with different races like Fish-Men, Buccaneers, Giants, etc.

However, in the case of Fish-Men, Joy Boy knew that they had the power of Poseidon, and thus, in order to use the Ancient Weapon’s power, Joy Boy made a deal with them that involved the creation of Noah and using it to carry the entire Fish-Man Island above the sea. But because Joy Boy lost the war, he could not fulfill his part of the promise.

This theory explains a lot about Joy Boy’s promise, the creation of Noah, and the use of Ancient Weapons. But the main thing it explains is the brutal slavery that the people of Fish-Man Island had to face whenever they came to the surface world. Their connection with Joy Boy might be the reason why they are tortured to such extent. Thus, in a way, Joy Boy might be responsible for the struggles and subjugation that the Fish-Man has been facing since the Void Century.
