Stanley Snyder

Stanley Snyder is a major antagonist in the Dr. Stone anime (particularly prominent in the later arcs involving the American colony).

He serves as the loyal right-hand man and second-in-command to Dr. Xeno, acting as a highly skilled ex-military operative (former U.S. military officer with elite combat and sniper expertise). In the anime, he's depicted as calm, composed, and ruthlessly efficient—often a "shoot first, ask questions later" type who shows little hesitation in using lethal force to protect Xeno's goals or eliminate threats to their scientific empire.

Stanley is extremely prideful about his combat abilities and maintains a cool, disciplined demeanor. He has a notable habit of constantly smoking cigarettes.

His appearance stands out with strikingly attractive, almost androgynous features for a tough soldier archetype: tall and well-built, with neatly slicked-back blond hair (a prominent strand falling over his face), relaxed brown eyes with thick lashes, arched eyebrows, and glossy lips—giving him a polished, model-like look that contrasts his deadly profession.

(He's voiced by Kōji Yusa in Japanese and Robert McCollum in English.)
