Loki may answer One Piece's biggest Fishman Island Arc question

The Fishman Island arc in One Piece left fans with a lingering question about why Luffy will destroy the island, as Madam Shyarly’s prophecy foretold. Recent developments and theories suggest that this pivotal moment may not unfold as expected.

Enter Loki, a character shrouded in Norse mythological symbolism, who claims to be the Sun God, posing a direct challenge to Luffy’s role in bringing the world’s dawn. With the potential for Loki to disguise himself as Luffy, new speculation arises that Loki, not Luffy, may be responsible for the destruction of Fishman Island.

In One Piece chapter 1130, Loki introduces himself as the Sun God, despite speaking to Luffy, who is recognized as the true Sun God. Loki declares,

"I am the Sun God who will bring about the end of the world."

The above line is a clear nod to Norse mythology and Ragnarok.

In Norse legends, Loki is known for shapeshifting and impersonating gods. This theory suggests that Loki's Devil Fruit is powerful and ancient, allowing him to transform into anyone or anything at will. While Catarina Devon possesses a similar Devil Fruit, Loki's seems to be a stronger, more legendary version passed down through the royal family.

Loki’s portrayal of the Sun God sets him up as an antagonist to Luffy, who doesn’t claim to be a god but aims to bring the dawn of the world. This contrast mirrors the mythological battle between gods in Ragnarok. The theory proposes that Loki and Luffy's clash could trigger a Ragnarok-like event, not just in Elbaf but potentially impacting the entire world.

One potential connection is Madam Shyarly’s prophecy from the Fishman Island arc, where she foresaw Luffy destroying the island. The theory suggests Loki, disguised as Luffy, could be responsible for this destruction, possibly sinking the island.

Additionally, the Noah’s Ark, the only means of transporting the Merfolk to the surface, could be destroyed during this event. Loki might also take Shirahoshi, the ancient weapon Poseidon, hostage, using her power to sink islands.

The theory draws parallels between Loki and Usopp, with the latter potentially leading the giants in a rebellion against Loki. If Luffy releases Loki, it will align with Norse mythology, where Loki breaks free before Ragnarok, setting the stage for an apocalyptic event.

One Piece: Another theory about why Luffy would destroy the Fishman Island

While the theory that Loki would be destroying Fishman Island as Luffy makes sense, there was another theory about why Luffy would destroy their island.

The theory that Luffy will destroy Fishman Island after becoming the Pirate King revolves around key themes in One Piece, particularly freedom, racism, and equality. While the destruction might seem catastrophic, it could ultimately represent liberation for the Fishmen and their transition to life on the surface, dismantling the prejudice they’ve faced for generations.

At the heart of this theory is Madam Shyarly's prophecy, which accurately foretells that Luffy will destroy Fishman Island. Although Luffy saves the island during the Fishman Island arc, this prophecy suggests his future actions will bring its downfall.

The destruction may symbolize the end of the Fishmen’s oppression, as their underwater home reflects their marginalized status in the world. By destroying it, Luffy could pave the way for their integration into human society on the surface.

Fishmen have long dreamed of living under the "true sun," as their current light comes from the Sunlight Tree Eve. Destroying Fishman Island would allow them to finally experience real sunlight, fulfilling this desire for freedom and equality. Moreover, Luffy’s actions could challenge deep-rooted racism, pushing for a peaceful world where Fishmen and humans live together.

There are different ideas on how Luffy might bring about this destruction. One possibility is that Luffy will be forced to protect the island from an external threat, such as the World Government, which results in its destruction.

Another theory involves Shirahoshi, the ancient weapon Poseidon, using her ability to command Sea Kings to help relocate the Fishmen. Noah’s Ark, meant to bring them to the surface, could symbolize hope and new beginnings. Alternatively, the "destruction" might be metaphorical, representing a societal transformation for the Fishmen rather than a literal obliteration of the island.

Final thoughts

Loki's potential role in the destruction of Fishman Island could answer one of One Piece's biggest mysteries. Whether disguised as Luffy or triggering a Ragnarok-like event, his actions may fulfill Madam Shyarly's prophecy, reshaping Fishmen’s fate and symbolizing their transition to freedom and equality.
