Prince Loki’s Ragnir hammer is proving to be Elbaf’s most ‘out-of-the-box’ weapon with three levels of destructive power, enough to make even immortal entities like the Five Elder Stars wary.
In recent chapters of One Piece, the appearance of Prince Loki has brought a breath of fresh air full of drama. But besides Loki’s personal strength, what makes readers gasp is Ragnir – a hammer with a shape reminiscent of Mjolnir but in an “Elbafized” version.
Ragnir is larger than Loki, who is already larger than a normal giant. Even when placed next to Hajrudin, Ragnir still looks completely unbalanced. This confirms the fact that Ragnir is a unique weapon, made specifically for Loki and no normal giant can lift it.
So, where does Ragnir’s true power lie? Let’s take a look at 3 reasons why it is the most dangerous weapon at the present time.

1. The hammer prevented many kings from eating Elbaph’s devil fruit
Inside Elbaf’s Aurust castle is kept an heirloom devil fruit, a symbol of the kingdom’s ultimate power. In theory, any king who eats it will become unrivaled. However, for centuries, no king of Elbaf dared to touch it. The main reason is Ragnir.
Ragnir is not an inanimate object, it is a “living hammer” that has eaten a mysterious squirrel devil fruit, possessing an independent will. It acts as a ferocious gatekeeper. Anyone intending to eat the royal devil fruit must pass Ragnir’s test of violence. This is not a symbolic ritual, but a real life-and-death battle.
Even King Harald – the most majestic and powerful king – never dared to challenge Ragnir until he was manipulated by Imu and achieved immortality. On the contrary, Loki chose the path of direct confrontation. In an urgent situation, Loki fought Ragnir, resulting in his old hammer being broken, and Ragnir had… a huge swelling on his head. It was this strength that made Ragnir acknowledge Loki as a worthy master.
2. The weapon that killed King Harald
King Harald, when controlled by Imu, became a true monster. With immortality from the “Deep Sea Contract” combined with Conqueror’s Haki, Harald is almost unstoppable. Even legends like Scopper Gaban or Shanks had difficulty finishing this king.
Everything only changed when Loki appeared with Ragnir.
The combination of Ragnir’s physical strength, Loki’s Conqueror’s Haki and the new devil fruit’s abilities created a devastating combo. The blow from Ragnir was heavy enough to shake Imu’s control, allowing Harald to briefly regain consciousness. Its penetrating force penetrated Harald’s Haki Conqueror’s defense.
Even a series of all-out attacks includes enormous physical pressure, maximum Haki pressure, and bolts of lightning falling from the sky with each swing of the hammer. It was this resonance that caused Harald’s immortal body to shatter, ending the nightmare on Elbaf.
3. Ragnir is in the hands of the giant best suited to use it
If Ragnir fell into the hands of a normal giant, it would be just a heavy hammer. But in the hands of Loki – who has Ancient Giant blood, it is a completely different story.
What makes Ragnir truly terrifying is that it is held by someone with extreme physical strength and endurance like Loki – whose physical body perfectly matches the terrifying mass of this great mace. In the hands of Prince Elbaf, the ability to cover the weapon with Conqueror’s Haki is the “soul” that makes Ragnir unmatched.
Every time Loki swings his hammer, his opponent will face a nightmare called “three layers of destruction” taking place simultaneously. The first is the tremendous physical impact force from the living hammer entity’s unbelievable mass. Next is the huge internal mental pressure from Conqueror’s Haki. Finally, meteorite lightning strikes down with each attack.
It is this devastating resonance that causes the enemy to not simply be defeated, but all of their defenses will be crushed to pieces in the moment of impact.
Conclusion: How strong is Ragnir?
The world of One Piece is approaching the final war, where immortal enemies such as the Gorosei, the Holy Knights or Imu himself are dominating. Wounds from normal swords or bullets can heal in an instant, but receiving a full blow from Elbaf’s great hammer, covered in Conqueror’s Haki and accompanied by a lightning strike… it is definitely a completely different experience.
Ragnir is currently not only Elbaf’s strongest weapon, but also one of the most dangerous weapons in the One Piece world.
