Senku Ishigami is the main character of Dr. Stone, a genius scientist determined to rebuild civilization after humanity is petrified for thousands of years. Instead of relying on strength, Senku uses science, chemistry, engineering, and intelligence to recreate modern technology from scratch. He has sharp red eyes, wild white-and-green hair, a thin build, and petrification marks across his face. Calm, sarcastic, logical, and obsessed with science, Senku rarely panics and never gives up, always recalculating after failure. Though smug and dramatic, he genuinely wants to save everyone and rebuild humanity fairly. His famous phrases include “Get excited!”, “Ten billion percent!”, and “Science is elegant.”

Ryusui Nanami is a wealthy prodigy, expert sailor, businessman, and one of the most charismatic characters in Dr. Stone. After being revived in the Stone World, he becomes the crew’s navigator and captain, helping rebuild civilization through trade, exploration, and leadership. Ryusui is loud, theatrical, ambitious, and proudly admits he wants everything — wealth, adventure, technology, luxury, and discovery. Unlike selfish villains, his greed inspires progress and pushes humanity forward. He has sharp blue eyes, messy blond hair, petrification marks across one side of his body, and flashy captain-style clothing. His iconic lines are: “I desire (name)!” “I want it all!”

Taiju Oki is one of the main characters in Dr. Stone and Senku’s childhood best friend. Unlike Senku, Taiju relies on pure strength, stamina, and determination rather than intelligence or strategy. After humanity is petrified for thousands of years, Taiju helps Senku rebuild civilization through hard work, loyalty, and physical labor. He has a tall, muscular build, messy dark hair with a large curl, kind eyes, and petrification marks on his face. Taiju is loud, emotional, energetic, and incredibly kind-hearted, always putting others before himself. Even though he isn’t a scientist, he never gives up and supports his friends no matter how impossible things seem. His biggest strength is his endless endurance and genuinely caring nature.

Gen Asagiri is a clever mentalist known for manipulation, psychology, and charisma. Though sneaky and dramatic, he becomes one of Senku’s most loyal allies and uses deception to help science win. He has short black and white split hair, side bangs longer on the white side.
