In recent chapters of One Piece, the arrival of Prince Loki has brought fresh and intense drama. Beyond Loki’s own strength, what truly amazes fans is Ragnir, a hammer that resembles Mjolnir but with a distinct Elbaf twist.
Ragnir is enormous, even larger than Loki himself, who is already bigger than an average giant. Even next to Hajrudin, the hammer looks wildly disproportionate. This confirms that Ragnir is a unique weapon, crafted specifically for Loki, and no ordinary giant could lift it.
So, what exactly makes Ragnir so powerful? Let’s explore three reasons why it’s currently the most dangerous weapon.
1. The hammer has stopped many Elbaf kings from eating the Devil Fruit

Inside Elbaf’s Aurust castle lies a hereditary Devil Fruit, symbolizing the kingdom’s ultimate power. In theory, any king who consumes it would become unbeatable. Yet for centuries, no Elbaf king has dared to touch it. The main reason is Ragnir.
Ragnir is no ordinary weapon, it is a “living hammer” that has consumed a mysterious squirrel-type Devil Fruit, granting it independent will. It acts as a fierce guardian. Anyone who tries to eat the royal Devil Fruit must first pass Ragnir’s violent test. This is not a symbolic ritual but a deadly battle.
Even King Harald, the most majestic and powerful king, never dared challenge Ragnir until he was manipulated by Imu and gained immortality. In contrast, Loki chose to confront it head-on. In a desperate fight, Loki battled Ragnir, shattering his old hammer while Ragnir ended up with a huge swelling on its head. This toughness led Ragnir to acknowledge Loki as its worthy master.
2. The weapon that ended King Harald

Under Imu’s control, King Harald became a true monster. With immortality from the “Deep Sea Pact” combined with Conqueror’s Haki, Harald was nearly unstoppable. Even legends like Scopper Gaban and Shanks struggled to finish him off.
Everything changed when Loki appeared wielding Ragnir.
The combination of Ragnir’s physical power, Loki’s Conqueror’s Haki, and the abilities from his new Devil Fruit created a devastating combo. Ragnir’s strikes were heavy enough to disrupt Imu’s control, briefly restoring Harald’s awareness. Its piercing force broke through Harald’s Conqueror’s Haki defenses.
A relentless barrage of massive physical pressure, intense Haki force, and lightning strikes from the sky accompanied each swing. This brutal synergy shattered Harald’s immortal body, ending the nightmare at Elbaf.
3. Ragnir is in the hands of the perfect giant to wield it

In the hands of a normal giant, Ragnir would just be a heavy hammer. But with Loki, who carries Ancient Giant blood, the story is completely different.
What makes Ragnir truly terrifying is that it’s wielded by someone with immense size and endurance like Loki, whose physique perfectly matches the hammer’s massive weight. As Elbaf’s prince, Loki’s ability to coat the weapon with Conqueror’s Haki is the “soul” that makes Ragnir unbeatable.
Every time Loki swings the hammer, opponents face a nightmare of “triple-layered destruction” happening simultaneously. First is the overwhelming physical impact from the living hammer’s unimaginable mass. Next is the intense mental pressure from the Conqueror’s Haki covering it. Finally, meteor-like lightning bolts strike with each blow.
This brutal combination means enemies aren’t just defeated, all their defenses are utterly crushed the moment they clash.
Final thoughts: How strong is Ragnir?
The One Piece world is approaching its final battle, where immortal foes like the Gorosei, the Holy Knights, and Imu dominate. Wounds from swords or bullets heal instantly, but taking a full hit from Elbaf’s giant hammer, reinforced by Conqueror’s Haki and lightning strikes, is an entirely different experience.
Ragnir is not only the strongest weapon in Elbaf but also one of the deadliest weapons in the entire One Piece world.
