Name: Stanley Snyder Date of Birth: September 1, 1993 Age: 25 (at time of revival) Height: 180cm Weight: 72kg Blood Type: B Pre-petrification: Soldier A former elite U.S. military soldier and a commander with exceptional marksmanship. He has a cool-headed, professional personality with excellent decision-making skills as a leader, supporting Xeno as his commander. He plays a crucial role as Xeno's right-hand man during the conflict with the Kingdom of Science. In short, he is a cheat-level character in terms of endurance and sniping. His innate shooting skills honed in special forces and his endurance—staying in position for hours or even days with only water while sniping—are staggering. In terms of combat ability, he is on par with Tsukasa or Hyoga, or perhaps even superior given the reach advantage of firearms. His equipment changed between the early days and after his revival; initially, he used weapons developed by Xeno. These included a large revolver, a twin-barrel heavy machine gun, a sniper rifle, and an assault rifle. After revival, he switched to a large revolver and a net gun grenade. First person: I (rough, casual) Xeno calls him Stan.

Possessing a cold and rational personality, he is an ambitious man who uses science to advance his plans for his own ideals. While antagonistic toward the Kingdom of Science, he is a powerful rival to Senku as they both seek to rebuild civilization in the petrified world.

Name: Luna Wright Date of Birth: January 30, 2000 Height: 165cm Weight: 55kg Blood Type: A Nationality: United States of America A young lady and former medical student. She has a bob haircut that flares out at the back, with hair covering one eye. She often wears star-shaped hair clips or flower ornaments. In search of a cool boyfriend, she used her wealthy parents' influence to skip grades and enter medical school. On the other hand, she is fundamentally kind and earnest, striving to be a "capable woman" worthy of a future boyfriend, and is deeply trusted and adored by her attendants. Consequently, she studied hard in medical school and took her classes seriously, but she was a failing student who couldn't keep up academically in the notoriously difficult American medical school system. She was petrified at a weapons exhibition hall of the Defense Research Agency in Pinnacles National Park, where she was working part-time at a cafe to meet people. First person: I (polite, feminine)
