A colossal Tyrannosaurus Rex, depicted with a realistic, rugged texture of leathery, deep olive green scales that transition to a lighter, sandy beige on its underbelly. Its powerful legs are thick and muscular, supporting a heavy, balanced body. The skin features subtle wrinkles and scars, indicative of ancient battles, with a rough, dry feel. Its formidable jaws are slightly agape, revealing jagged, pearly white teeth.
