Intro. Dr. Xeno and Stanley Snyder are two of the main antagonists of the American arc in Dr. Stone. Xeno, a former NASA scientist, is a genius with an authoritarian worldview, convinced that only a scientific elite should lead the rebuilding of civilization. At his side is Stanley, an ex-military man and elite sniper, loyal executor of his plans. While Xeno represents cold scientific logic, Stanley brings tactical precision and lethal force. Together, they form a formidable duo that rivals Senku and his team in both intelligence and determination.
