Complete List of the Main Characters of Dr. Stone
There are anime that define a generation through their fights, others through their romances, and others through their mysteries. Dr Stone, however, chose a radically different and incredibly effective path: turning science into an epic adventure, and making human knowledge the most formidable weapon against a world that has returned to the wild.

Written by Riichiro Inagaki and illustrated by the prodigy Boichi, this anime plunges all of humanity into a mysterious petrification before bringing it back to life, 3,700 years later, in a Stone World where everything must be rebuilt from scratch. At the heart of this colossal reconstruction are characters of exceptional depth and complementarity, each bringing a skill, philosophy, or energy essential to the survival of the Kingdom of Science. The complete list of Dr Stone's main characters is like humanity in miniature: passionate, imperfect, and magnificent. For anime fans and collectible figures, every member of the Kingdom of Science deserves a special place in the display case.
The complete list of essential Dr Stone characters
1. Senku Ishigami
Senku Ishigami is the absolute brain of Dr Stone, a scientific prodigy whose stratospheric IQ and encyclopedic memory represent humanity's only true advantage against a world that has forgotten everything. With his eternal smirk, improbable green hair, and catchphrase "ten billion percent", Senku embodies a philosophy that is as simple as it is revolutionary: any situation, no matter how desperate, can be solved through scientific rigor and creativity. As the adopted son of astronaut Byakuya Ishigami, he carries a legacy of love and sacrifice that gives deep emotional weight to his appearance as a pure rationalist. His project to rebuild civilization at high speed, from the wheel to the rocket, is one of the most exhilarating narrative concepts in modern anime. As a Dr Stone collector figure, Senku in his lab outfit with his calculating gaze is the essential piece for any collection dedicated to this universe.
2. Taiju Oki
Taiju Oki is Senku's best friend and his first companion in the Stone World, a kind-hearted giant whose physical strength and extraordinary endurance make up for his complete lack of scientific sense. If Senku is the brain, Taiju is the muscle and the heart: unable to strike an enemy because of his deeply pacifist nature, he can still stand for hours under any conditions to complete a repetitive task. His absolute devotion to Senku and his sincere, awkward love for Yuzuriha make him one of the purest and most endearing characters in the anime. He is the one who unintentionally sets the whole adventure in motion by choosing to wake up at the exact moment he was about to confess his feelings. His anime figure, colossal and smiling, radiates a warm kindness that feels good in any Dr Stone collection.
3. Kohaku
Kohaku is the warrior of Ishigami Village and the first ally Senku finds in the Stone World, a fighter with fearsome agility and power who chooses to join the Kingdom of Science out of love for her sick sister. Direct, impulsive, and proudly lionhearted, she brings the group an essential ability to protect itself in a world without firearms or defensive technology. Her development across the seasons, from a solitary warrior to a strategist capable of combining brute strength with scientific tactics, is one of the most satisfying arcs in the series. Her determined gaze and blonde ponytail make her one of the most iconic designs in Dr Stone. A Kohaku figure in a combat stance, spear in hand and fierce eyes locked forward, is a piece with absolutely striking energy and presence in any anime collection.
4. Chrome
Chrome is the "sorcerer" of Ishigami Village, a self-taught teenager who spent his entire childhood collecting minerals and experimenting with natural materials without realizing that, in his own way, he was reinventing the foundations of chemistry and physics. His meeting with Senku is a mutual revelation: while Senku brings theory and method, Chrome brings practical field knowledge and experimental intuition that often proves decisive. Enthusiastic, courageous to the point of recklessness, and driven by an insatiable curiosity for everything science can accomplish, he quickly becomes the most valuable apprentice Senku could have hoped for. His personal arc, marked by his capture and resistance against the Empire of Might, reveals resilience and ingenuity that even Senku had not suspected. His collector figure with his mineral collector's bag is a piece with irresistible natural charm.
5. Tsukasa Shishio
Tsukasa Shishio is the first and most formidable antagonist of Dr Stone, nicknamed the "Strongest High School Primate," a description that does not do justice to the true extent of his combat abilities. With his cold beauty and a philosophy built on the belief that adult civilization was fundamentally corrupt, he seeks to build a new world by reviving only the young, whom he sees as free from the vices of the old world. What makes Tsukasa so fascinating is that his ideology is not simple nihilism: it is born from a real wound, a desperate brotherly love, and a worldview that is as coherent as it is dangerous. His philosophical clash with Senku, two brilliant minds each refusing to bend to the other's logic, is one of the most intense narrative duels in the anime. His anime figure in a free combat pose is a piece of majestic visual power.
6. Gen Asagiri
Gen Asagiri is a former mentalist and illusionist from the old world, a character whose initial duplicity and talent for manipulation make him seem dangerous before he gradually reveals a loyalty that is as sincere as it is unexpected. Sent by Tsukasa to spy on the Kingdom of Science, he eventually chooses Senku's side for reasons that begin with personal interest and end in genuine friendship. His mastery of human psychology and his ability to lie with unsettling ease become incomparable strategic assets in a world where persuasion can be worth as much as a bomb. His relaxed style, two-tone hair, and professional showman's smile make him one of the most stylish designs in Dr Stone. As a collectible figure, Gen with his poker-player gaze is a piece with instantly recognizable charisma.
7. Ryusui Nanami
Ryusui Nanami is the navigator and captain of the Perseus, the ship of the Kingdom of Science, a man whose unapologetic arrogance and mastery of almost every field of skill make him as infuriating as he is indispensable. Former heir to a colossal fortune in the old world, he has carried through petrification a thirst for possession and excellence that now expresses itself in a radically different context. His iconic line, "I want everything," perfectly reflects a personality whose appetite for competence has no limit: navigation, diving, piloting, gourmet cooking, he masters everything with unsettling ease. Beneath the arrogance, however, lies a reliable teammate and courageous leader whose decisions at sea regularly save the entire expedition. His anime figure, with a conquering smile and captain-like presence, is one of the most charismatic pieces in the entire Dr Stone universe.
8. Suika
Suika is the little spy with the watermelon mask, the youngest member of the Kingdom of Science and undeniably one of the absolute fan favorites of Dr Stone. Severely nearsighted in a world without glasses, she developed the habit of wearing a hollowed-out watermelon helmet as an improvised vision aid, creating one of the most unlikely and heartwarming designs in the entire anime. Small, discreet, and agile enough to sneak anywhere, she regularly serves as a spy and scout for the group with a seriousness and dedication that command respect. Her arc in the America storyline, where she is left alone to carry the survival of the Kingdom of Science on her shoulders for years, reveals resilience and courage on a scale no one would have suspected. In Dr Stone merchandise, Suika with her watermelon helmet is the absolutely essential collector mascot of the franchise.
9. Yuzuriha Ogawa
Yuzuriha Ogawa is Taiju's quiet love and one of the first people revived in the Stone World, a young woman whose gentleness and manual skill conceal strategic intelligence and courage that are regularly underestimated. Gifted with exceptional ability in precision work, she plays a crucial role in several key operations of the Kingdom of Science, especially in reconstructing petrified statues to make the enemy believe their attacks had no effect. Her loyalty to Taiju and her trust in Senku's project are discreet but solid emotional pillars of the series. Yuzuriha embodies the rare kind of gentle character whose value is never spectacular but always decisive. Her anime figure, serene and smiling, brings a bright touch of tenderness to any Dr Stone collection.
10. Kinro and Ginro
Kinro and Ginro are the two guardian brothers of Ishigami Village, a funny and endearing duo whose diametrically opposed personalities create a dynamic that works just as well for humor as it does for combat. Kinro, the older brother, is inflexibly serious and almost comically rigid in his sense of righteousness, attached to the village rules with a consistency that earns him both respect and teasing. Ginro, his younger brother, is the exact opposite: cowardly, opportunistic, and always looking for the strategy that benefits him personally, yet capable of sincere acts of bravery when the situation truly leaves him no choice. Together, they form one of the funniest duos in Dr Stone, and their golden and silver spears have become instantly recognizable visual symbols. As collector figures, the Kinro and Ginro duo is the essential double piece for fans of the series.
11. Kaseki
Kaseki is the master craftsman of Ishigami Village, an old stoneworker whose talent for shaping materials with extraordinary artisanal precision proves absolutely crucial to Senku's industrial ambitions. Gruff and possessive of his workshop at first, he is literally transformed by the discovery of science: the child of ancestral techniques marvels like a kid at every new invention, finding in his collaboration with the Kingdom of Science a youth and enthusiasm he thought he had lost long ago. His improbable muscles for an elder, revealed during moments of intense work, are one of the series' most beloved recurring jokes. Kaseki embodies the perfect bridge between traditional craftsmanship and scientific innovation. His anime figure, hammer in hand and eyes sparkling, is a collector piece full of warmth and character.
12. Nikki Hanada
Nikki Hanada is a former elite athlete from the old world, revived in the Stone World and brought into the Kingdom of Science thanks to her absolute passion and encyclopedic knowledge of the singer Lillian Weinberg, which proves to be a strategic asset in the most unlikely negotiations. Tall, powerful, and disarmingly straightforward, she combines physical strength that lets her rival the group's best fighters with a totally unexpected musical and romantic sensitivity, creating an instantly endearing comic duality. Her integration into the Kingdom of Science is the perfect example of Senku's philosophy: every skill, no matter how specialized or unlikely it may seem, has value in rebuilding the world. In Dr Stone merchandise, Nikki in combat attire is a surprising and memorable piece that delights the most attentive fans of the series.
13. Hyoga
Hyoga is the lieutenant of Tsukasa's Empire of Might, a spear fighter of absolute elegance and danger who represents one of the most serious physical threats in all of Dr Stone. Unlike Tsukasa, whose ideology is fueled by a real emotional wound, Hyoga seems driven by pure nihilism and a fascination with destruction that makes him even more unpredictable and chilling. His mastery of the Whirlwind spear technique, capable of cutting through any defense with terrifying fluidity, makes him an opponent whom even the best fighters of the Kingdom of Science cannot face head-on. His true motivations and his complex relationship with the very idea of a rebuilt society make him a far more nuanced character than he first appears. His anime figure, spear in attacking stance and icy gaze fixed ahead, is a piece of formidable sophistication in any collection.
14. Dr Xeno
Dr Xeno is Senku's American counterpart, the genius scientist who survived petrification and rebuilt, on his own side in the United States, an advanced technological civilization with motivations and a philosophy radically different from those of the protagonist. A former mentor to Senku in the old world, he embodies what scientific intelligence can become when combined with a cold vision of progress and survival without the moral restraints Senku imposes on himself. His introduction in the later arcs of the series profoundly changes the scale of the stakes: it is no longer about rebuilding a Japanese village, but about determining which philosophy will govern the rebirth of all humanity. His refined scientist's outfit and eagle-like gaze make him an antagonist of rare presence. As a Dr Stone collector figure, Dr Xeno is the piece that completes and elevates any collection from the America season.
15. Byakuya Ishigami
Byakuya Ishigami is Senku's adoptive father and the Japanese astronaut whose silent sacrifice, carried out 3,700 years before the main events of the series, forms the most moving emotional foundation in all of Dr Stone. The only survivor of petrification in Earth's orbit, he returned to an empty Earth with his fellow astronauts to try to preserve everything that could be saved of human knowledge, knowing perfectly well that he would never have the chance to see his son again. His arc in the spin-off anime and his flashback appearances in the main series reveal an ordinary man, not especially brilliant scientifically, but filled with a paternal love so deep that he literally planted the seeds of civilization's rebirth for a child he would never see again. His invisible but omnipresent legacy in the Dr Stone universe makes him a central emotional figure. His anime figure in a spacesuit is the most emotionally charged collector piece in the entire franchise.
