Wadatsumi

Wadatsumi is an undersea giant "umibozu" in the service of Captain Van der Decken.

Appearance
Wadatsumi is a colossal sea giant, appearing only a little smaller than a Kraken. His round head and chest are quite big in comparison to his arms and legs. He has a big, round face, with a large mouth full of massive, round teeth quite distant from one another, and childlike eyes. He has some stubble on his chin and dark hair surrounding all of his head, taking the shape of a protrusion pointing upwards on the top, which also covers part of his shoulders; his whole body is also quite hairy. He apparently wears a pair of extremely loose pants paired with a dark indument tied around his waist; and some sort of boots-like footwear. His overall shape strongly resembles Sanjuan Wolf's.

Abilities and Powers
Being a giant, he is very strong. He shows his immense strength by hurting Ankoro, an angler fish several times the size of the Thousand Sunny, with a single punch, even though the punch was only intended to prevent the fish from eating the Straw Hat Pirates, and not to harm him. Also, living in the depths of the Grand Line, he's capable of breathing underwater, much like Fishmen. As of yet, it is unknown if he possesses either lungs, gills, or both.

History
While the Straw Hats (minus Luffy, Zoro, and Sanji) are sailing through the underworld of the sea, Wadatsumi suddenly appeared from the rocks beneath the sea. He beats an angler fish with one blow to prevent it from eating the Thousand Sunny because the captain of the Flying Dutchman, Van Der Dekken, wants treasure. On Van Der Dekken's orders, Wadatsumi attempts to punch Thousand Sunny, but the Kraken (which has been tamed by Luffy, Zoro, and Sanji) intervenes and knocks out Wadatsumi.

Trivia

 * His size, eye style, and head shape all greatly resemble San Juan Wolf.
