Wadatsumi is a character from One Piece - Big Secret Treasure of the Seven Phantom Islands. He is Hei's pet whale.[1]


Wadatsumi is a small, orca with a light-grey underbelly and an X-shaped scar on his snout. He has a golden star on the side of his face and wears a gold piercing on his dorsal fin.[1]


Wadatsumi is very obedient to his owner, Hei, appearing on the island and transporting Luffy and his crew when told.

Abilities and Powers

Wadatsumi, as an orca, has the strength to carry many people on his back. He is surprisingly fast, transporting the Straw Hat Pirates from one island to another in less than a few hours.


Big Secret Treasure of the Seven Phantom Islands

Wadatsumi, when he was summoned by Hei, appeared at the island where his owner was located. When he surfaced from the ocean, he scared Usopp and Chopper. Luffy, however, was impressed by the creature as soon as he saw it. Hei ordered his pet to transport him and the pirate crew to his island hideout. Once they arrived, Wadatsumi waited on the coast as everyone else went inland.

After the Straw Hat Pirates explored the island's mountain lair, Wadatsumi carried them back to the original island, but they were intercepted by Rubis, Saphir, and Emeraude. The pirates defeated the three fish-women, and Wadatsumi carried them along to their destination.
