Appearance: Has an appearance that strongly conveys an intellectual and calm impression. The most striking feature is his white hair, and his neat hairstyle suggests a meticulous personality. His features are sharp and lean, and his composed expression gives off the vibe of someone who is "always thinking." He also has a large black X-shaped petrification scar on his forehead. He basically wears a black doctor's coat, symbolizing his position as a scientist. The overall look is clean and simple, emphasizing functionality and rationality. His physique is slender, giving a strong impression of an intellectual rather than a muscular type. He also wears long metal claw-like attachments on his fingers. The sharp glint in his eyes and the faint smiles he shows at times radiate confidence and overwhelming intelligence.

<Xeno's Past> While working at NASA, he proposed research and experiments, but most were rejected due to "political issues," etc. → This warped Xeno's ideology.

He is childhood friends with Stanley. They reunited in the post-petrification world and have walked the path toward dictatorship together, combining Xeno's scientific power and Stanley's marksmanship.
