One Piece Episode 1160: the Terrifying Arrival of Loki, the Accursed Prince
Episode 1160 also confirms critical background lore that manga readers debated for months. Loki sits in chains because he murdered King Harald, his own father, to consume an ancient Devil Fruit passed down through Elbaf's royal lineage. The nature of that fruit remains obscured, but the visual cues in the anime highlight thick, smoking auras and animalistic hostility that terrified the giant elders.
This patricide explains why the entire warrior civilization turned against him. Giants value honor and ancestral lineage above all else. By slaying Harald, Loki severed the moral code of Elbaf. The entire warrior caste, including the New Giant Warrior Pirates led by Hajrudin, mobilized to chain him to the Underworld tree. Even so, the sheer manpower required to keep him restrained highlights his monstrous baseline strength, even with his abilities dampened by Seastone.
The narrative places Luffy in an impossible position. Luffy loves rebellion and instinctively distrusts authority figures who keep people locked in cages. Yet Loki is no sympathetic victim. He openly insults the giants, mocks the peace of the island, and makes no secret of his destructive ambitions. The tension in Episode 1160 stems entirely from this moral ambiguity: Luffy wants to explore, but freeing Loki could mean setting fire to the very land he promised to visit alongside Dorry and Brogy.
