By part 3, the focus on reviving more people will increase, with important people such as mathematician Sai Nanami and others. They will be exploring how the World has changed by going Global (Globetrotting Arc), and preparing for the greatest project of humanity, building a spaceship to confront the mysterious “Why-man” on the Moon. There will be many themes about the themes of science, innovation, exploration, making alliances, and the goal of restoring civilization. Much of the teaser trailers will showcase high-stakes advancement, such as powerful engines and global travel.

Overall, Dr. Stone is a Fun/Educational series full of creative problem-solving, humor, and some of the most exuberant optimism found in the character, Senku (10 Billion Percent).
