Ankoro is a gigantic anglerfish under the command of captain Vander Decken IX, residing in the Underworld of the Sea, seven thousand meters underneath the ocean surface. Wadatsumi seems to regard Ankoro as a pet, as apparently Ankoro was told "not to eat ships" before.
Ankoro is a giant grey-brown angler fish, with tiny white eyes, veiny fins, and a huge yellow light on the tip of its antennae.
When he was about to eat the Straw Hats' ship, he was stopped by Wadatsumi. Therefore, it seems Wadatsumi has a problem with Ankoro eating ships.
Abilities and Powers
He has a massive row of sharp teeth, so he is presumably ferocious and eats his prey.
- Its name comes from "ankō" (アンコウ?), the Japanese word for anglerfish.
