Harald One Piece Manga 1169
Gaban explains how to damage the immortals, basically, you coat your attacks with Conqueror’s Haki, which causes pain and slows their recovery.

Keep attacking repeatedly until they can’t fight anymore.
Gaban says he knows how to fight them because the Holy Knights tried to abduct Shanks several times, but they were defeated everytime by Roger’s Pirate.
Loki and Ragnir’s fight continues, but they’re exhausted. Loki’s hammer is broken, and Ragnir transforms into a cutie squirrel.

The squirrel accepts Loki and open the Devil Fruit chest, and Loki eats it. His hands turn into claws, but only his silhouette is shown.
Loki vs Harald continues, while Loki’s shape still isn’t clear, only a silhouette.
Loki, with Ragnir (in human form), lands the final blow on Harald, coated with Conqueror’s Haki and lightning. Shattering harald to pieces.
