Ankoro is a gigantic anglerfish formerly 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 it was about to eat the Straw Hats' ship, Ankoro was stopped by Wadatsumi. It seems Wadatsumi has a problem with Ankoro eating ships, since this would make retrieving treasure from the ship more difficult.
Abilities and Powers
It has a massive row of sharp teeth, so Ankoro is presumably ferocious and eats his prey.
