One Piece fans have been going absolutely wild over Loki's devil fruit ever since he showed up in the Elbaph Arc. The so-called Accursed Prince killed his own father, King Harald, just to get his hands on Elbaph's legendary devil fruit. And now, after months of theories and speculation, we might finally have an answer. But it's not what anyone expected.The buildup has been insane. Chapter after chapter, One Piece keeps reminding us that Loki's power is supposedly strong enough to destroy the entire world. That's a pretty massive claim, even in a series where characters can split islands in half. So naturally, fans have been cooking up theories left and right about what kind of fruit could possibly live up to that hype.The Leading Theories Before the RevealYonkou Mo @YonkouMoLINK#ONEPIECE1138 Im fucking genius Loki has the Serpent of Hell fruit Which can destroy the World. By YonkouMoBefore the recent leaks dropped, the One Piece community was all over the place with their guesses. The most popular theory was that Loki ate some kind of Norse mythology-based Mythical Zoan. That makes sense given the whole Elbaph Viking theme going on.namoRAC-K @RAK97943LINKCould the legendary fruit also be Jörmungandr as well? That would make sense considering that according to rocks a giant with ancient blood (Harald) is needed to unlock its true potential? Also could tie into the blood soaked serpent/Red line.Fenrir was a big one. The giant wolf from Norse mythology prophesied to swallow the sun during Ragnarok. Pretty fitting for a guy who refers to himself as the Sun God, no? Then there was the world serpent Jormungandr, which encircles the entire planet. That would certainly explain the whole “destroy the world” shtick One Piece keeps bringing up.Lunarian Leos @Lunar_LeosLINKSo the purple dragon in 1128 cover page could be referencing Loki? Not mad at it.Some fans guessed it might be the dragon Nidhogg, who eats away at the roots of Yggdrasil. Others threw into the ring Surtr, the fire giant who sets everything on fire during Ragnarok. A few even suggested Odin himself, though that seemed like a stretch.Weatherford @ZoroeEnmaLINKLoki having the Nidhogg DF makes total sense, Nidhogg already appeared as one of the children's nightmares and there's a dragon in the Harley Mural fighting the Hell Fire serpent. Loki is going to help Luffy against Imu/Hell Fire Serpent(Red Line).And here's where it gets interesting. There's also been serious discussion in One Piece circles about whether Loki actually has TWO devil fruits. Not in the Blackbeard way, but more like one fruit for himself and another one eaten by his weapon, Ragnir. The hammer seems to have a mind of its own, moving independently and attacking people. That's not normal hammer behavior.Konchiro Monk @tenyashawildLINKIf the devil fruit really is Nidhogg dragon And add to this his hammer with the ratatoskr devil fruit,Loki will be op as hellThe Ratatoskr Reveal Nobody Saw ComingBut then the leaks hit. And One Piece fans collectively lost their minds.According to recent spoilers for Chapter 1170, Loki's devil fruit might be the Mythical Zoan model Ratatoskr. Yes, the squirrel. The messenger squirrel that runs up and down Yggdrasil, spreading gossip between the eagle at the top and the dragon at the bottom.The reaction was immediate and brutal. Social media exploded with people threatening to drop One Piece entirely over a squirrel devil fruit. One post in particular went viral, with someone saying they'd have an excuse to drop the manga if Oda gave Loki a Norse mythology squirrel devil fruit.But here's the thing. A lot of One Piece fans who actually know their Norse mythology jumped in to defend it. Ratatoskr isn't just some random squirrel. In the myths, this creature literally tends to Yggdrasil, the world tree that holds all nine realms together. If Ratatoskr stops doing its job, the whole cosmological order collapses. That's pretty world-ending if you think about it.In addition, Ratatoskr is cunning, much like the mythological Loki. The squirrel is more than just a messenger. It distorts things, causes strife, and maintains the cosmic equilibrium in the face of chaos. Does that sound familiar? For the entire narrative, One Piece has essentially been preparing Loki for that.The Two Devil Fruit Theory in One PieceNormal and Weapon Funkfreed (Image Credit: Toei Animation)Now about that hammer. Recent chapters have heavily implied that Ragnir might have its own devil fruit power separate from Loki's. We've seen weapons eat devil fruits before. Spandam's sword, Funkfreed, was an elephant, and we know it's possible.If this theory holds up, then Loki might genuinely be the second character, after Blackbeard, to wield two devil fruit powers at once. Not by eating two fruits himself, but by having one and wielding a weapon that ate another. That would make him an absolute monster in combat.Some fans think Ragnir ate a Thor-related fruit, which would be perfectly ironic. In Norse mythology, Loki and Thor have a complicated relationship. Having Loki wield Thor's power through a weapon would be classic Oda storytelling.Whether One Piece will verify this in the upcoming chapters is the true question. Although we are aware that Loki may have consumed the Ratatoskr fruit, the Ragnir situation remains uncertain. We should learn more about the specifics of what's happening with that hammer in Chapter 1170.ConclusionWhatever the case, Loki is shaping up to be one of the most important characters in One Piece's final saga. A world-ending devil fruit user with possible ties to multiple powers? Yeah, that's definitely someone Luffy needs as either an ally or an enemy. And knowing how things work in this series, it's probably going to be both at different points.
