Legendary space cowboy with rugged charm in an anime style, blending the essence of John Wayne with the vibe of Cowboy Bebop and Trigun; a lone gunslinger navigating the cosmos in a futuristic western setting, wearing a worn leather duster and a wide-brimmed hat; sharp gaze and a trusty revolver at his side, exuding an air of confidence and resilience; the backdrop features a dusty, sprawling space frontier with distant asteroid fields and looming space stations, capturing the adventurous spirit of a western sci-fi epic.
