With Loki finally freed from his shackles, it is only a matter of time before we get the reveal of his Devil Fruit. So, I thought of this as the perfect opportunity to make a last-minute prediction. It’s been a hot minute since Loki was first introduced, so there has already been a lot of talk about his Devil Fruit, and it would be great if we examined some of the suggestions before settling on a pick.
For those who don’t want to read the whole post, you can just skip to the end where there is a TL;DR section with my prediction.
1. Fenris-wolf
Fenrir or Fenrisúlfr (often translated as “Fenris-wolf”) is a monstrous wolf in Norse mythology that plays a key role during Ragnarök. He is foretold to assist in setting the world aflame, resulting in the death of the god Odin and the destruction of the world. If this sounds familiar, it is because this is what Loki is said to have done (killing King Harold, his father) and what he is said to do (bring about the destruction of this world).
Besides the obvious similarities, Fenrir has another connection to Loki: along with Hel and Jörmungandr, Fenrir is a child of Loki. We’ve seen a “wolf” trying to protect Loki from the God Knights, so there seems to be a connection there.
Loki is said to be the leader of the beasts from the underworld, and as a Fenris-wolf he could be considered a “Leader of the Pack.”
According to Prose Edda, a text from the 13th century, it is unfortunate that Fenrir was bound by the gods due to his rapid growth and the foretold great troubles he would bring. As a result, Fenrir bit off the right hand of the god Týr, Lord of Swords.
Shanks is a character who is often compared to Tyr, not only due to their surface-level similarities - missing right arm, red hair, swordsmanship - but also because of what they represent: Honor. We now also know that Shanks was the one responsible for defeating and helping chain up Loki, for which the latter holds a great grudge.
2. Nidhogg, the Malice Striker
Níðhöggr, often anglicized as Nidhogg, is a serpent/dragon that gnaws at the roots of the world tree, Yggdrasil. Some sources suggest that Nidhogg is trapped in the very roots it gnaws on, preventing the beast from causing mayhem in the world. The root is placed over Niflheimr: the Realm of the Dead.
While not an exact 1:1 comparison, the similarities with Loki from One Piece are quite clear: Loki is chained to Yggdrasil at its base in the Underworld (the Realm of the Dead) to prevent him from causing mayhem.
In historical Viking society, níð was a term denoting a social stigma—implying the loss of honor and the status of a villain. This is where Loki’s status as the “Accursed Prince” could come from.
The most prevalent opinion among mythologists is that the arrival of Nidhogg heralds Ragnarök, which is similar to how Loki is prophesied to bring about the destruction of the world. However, as the prevalent themes of Norse mythology revolve around change and renewal, some of the poems concerning Nidhogg could be interpreted as the redemption of the serpent, shedding its corpses and beginning life anew (akin to a phoenix).
3. Mjöllnir, the Thunder Hammer
I think most people, if not everyone, are familiar with Mjöllnir, the hammer wielded by the thunder god Thor in Norse mythology. It has been featured prominently in several Marvel movies over the past 15 years, and in Chapter 1141 we see that Loki’s choice of weapon is also a hammer, called “Ragnir.”
In that same chapter we also learn that the two weaknesses of the Treasure Tree Adam are “Fire and Lightning.” Considering Loki is prophesied to destroy the world, this led people to believe that the hammer itself “ate” the legendary fruit, which then granted it lightning power with which Loki could burn down Yggdrasil. With Ragnir having lightning powers, it would match the depiction of Mjöllnir in Norse mythology.
While I see where people are coming from with this idea, it is important to remember that it was Vegapunk who figured out how to “feed” a Devil Fruit to an object. It was something he invented, meaning it couldn’t have existed before (the Devil Fruit is said to be passed down in Loki’s family). And while I’m sure there is a way to explain this as Vegapunk reverse-engineering the technology that created Ragnir—as well as the possibility of Ragnir having thunder powers—I believe there is one Devil Fruit that is more likely for Loki to have.
In fact, I believe the following Devil Fruit is the likeliest one.
4. Surtur, the Fire Giant
Norse mythology is filled with a plethora of mythical beings, with jötunn (jötun) being one of the most prominent—often contrasted with gods, dwarves, and elves. Jötnar are also commonly known as giants. Gerdr, Skadi, Grendel, and Ymir are all names of notable giants that appear throughout Norse mythology. However, even among the jötnar there are some that—much like Loki—are more special than others; those who set themselves apart from the rest. One such giant is Surtur.
Surtr is the greatest of the fire giants and serves as the guardian of Muspelheim, the fire realm—one of the two realms to exist before the beginning of time, alongside Niflheim. In both Poetic and Prose Edda, he is foretold to be a major figure during Ragnarök; with his “bright sword” he will battle against the gods, defeat one of the major gods (Freyr), and afterward engulf the Earth with his flames and destroy it. I believe this will be Loki’s Devil Fruit.
The two weaknesses of Treasure Tree Adam are “Fire and Lightning.” We have seen what lightning can do to it; it is time to see what fire can do.
Loki carries within him the blood of ancient giants, passed down by his father. He is far larger than your “regular” giant and sports those trademark ancient giant horns. In many depictions of Surtur, he is shown with similar horns and appears equally giant compared to his contemporaries. It is said that Loki was an arsonist—someone who enjoys setting things on fire—even before he obtained his Devil Fruit (another hint).
Loki is also a self-proclaimed Sun God, said to bring about the destruction of this world. If there exists a Devil Fruit that would make one believe they are the Sun God, then that would be the Devil Fruit that grants the powers of the sun (flames).
As the legend goes, Surtr will raise his flaming sword— from which “the light will shine more brightly than from the sun” —and plunge it into the Earth to “burn the whole world with fire.” This very sword can be seen plunged into the earth at the end of chapter 1130.
TL;DR
For those who just want to see my prediction, my guess is it would be something like Hito Hito no Mi, Model: Surtur. Loki is prophesied to bring about the end of the world, much like how Surtur is prophesied to do the same. Loki is an arsonist who calls himself the Sun God, while Surtur is the greatest of the fire giants. Both of them are massive in size and have similar horns. And if there is a being in Norse mythology that fits perfectly into the description of a “legendary Devil Fruit,” that would be Surtur.

Surtr moves from the south
with the scathe of branches:
there shines from his sword
the sun of Gods of the Slain.
