Create a visually striking image featuring a 12th-century samurai version of Marvel's Toxin. The character should be depicted in a traditional samurai uniform, complete with intricate armor details and a formidable samurai sword. Capture the moment in a classic samurai stance, emphasizing both strength and agility. The artwork should be presented on aged rice paper to enhance its authenticity, with elegant Japanese calligraphy surrounding the image to narrate the story of the symbiote samurai. The writing should explain the fusion of the symbiote with the samurai culture, creating an imaginative blend of historical and fictional elements. Focus on maintaining a balance between the traditional aesthetic and the dynamic, otherworldly presence of Toxin, highlighting textures and contrasts to enrich the visual narrative.
