Bonbori

An anglerfish in form but staggering in scale, Bonbori has dark red skin, fins colored red and white, and rows of needle-sharp teeth. Its defining trait is the enormous esca dangling from a stalk above its head, a lure that shines intensely and blazed brighter still once the complete Pure Gold was taken in. Three separate stomachs sit within the creature, each cradling islands, with Alchemi resting in the third.

An overwhelming pull toward the Pure Gold governs the fish, which swallows the treasure the instant it comes within reach.

Its colossal size lets the creature gulp down whole islands and ships in a single swallow, and taking in the Pure Gold granted it everlasting youth. Roughly two centuries before the present, the fish was drawn to the Pure Gold sealed inside Myskina Olga's ring, and while pursuing that one ring it engulfed almost all of Alchemi along with everyone living there. Olga eventually forced it to bring her back up so she could venture into the outside world. During Heart of Gold, after her ring slipped into the sea once more, the beast devoured it, swallowing both the Shark Emeralda and the Thousand Sunny in the process. Luffy then flung Mad Treasure against the inner wall of its third stomach, sending the fish into dry heaves; the vomiting dissolved the Pure Gold, brightened its lure, and the creature sank away beneath the surface.
