Dr. Stone begins when a mysterious flash of light turns every human on Earth to stone. 3,700 years later, teenage science genius Senku Ishigami breaks free and decides to rebuild civilisation from nothing, one invention at a time. The cast grows around three groups: the Kingdom of Science that Senku founds, the people of Ishigami Village who join him, and the Tsukasa Empire, a rival group that believes only the strong deserve a new world. Later arcs add the crew of a science ship and a scientist leading his own group in America. This page covers 16 characters, from Senku's first allies to the rivals of the Science Future season. Every profile stays at the point where the character is first introduced, so there are no spoilers.
