Create a highly detailed and realistic full-body image of a mature, muscular character with a distinct style. He has a white beard and hair tied in a topknot, and wears sunglasses. The character's muscular torso is visible, showcasing detailed tattoos over his arms and chest, and he wears a black vest with a loose open front. His attire includes a large gold belt buckle and baggy black pants that add to his tough demeanor. The character's stance is powerful and confident, and he holds a red staff-like weapon, adding to his warrior-like presence. The setting is dynamic with a vibrant purple neon-lit background, suggesting a modern, possibly cybernetic world. The image should be lifelike and proportionate, reflecting a 9:16 scale.
