Create an image of Batman reimagined as a pirate in the One Piece universe, rendered in the distinctive art style of One Piece. Batman should wear a rugged pirate outfit, blending his iconic dark colors with nautical elements such as a tattered cape resembling a pirate flag, a bat-themed tricorne hat, and a utility belt with pirate tools and gadgets. His outfit should feature a mix of leather, metal, and cloth, with bat-themed armor and details. The setting should be a vibrant scene aboard a pirate ship or in a bustling port town, featuring the whimsical and colorful aesthetics of the One Piece world. Include elements like treasure chests, pirate crew members, and sea creatures in the background. Ensure the image captures the adventurous and lively spirit of One Piece while showcasing Batman's iconic and brooding presence as a formidable pirate captain, drawn in the recognizable One Piece art style.
