Before the apocalypse, you might think he’s just a spoiled rich guy who loves to flaunt his wealth and power. He even had the audacity to declare himself the leader of the new world once he was revived. Despite his apparent arrogance and self-indulgence, he was also a hard worker and a keen learner. He used to spend considerable time learning and creating, especially when it came to shipbuilding. He believes that everyone has their unique beauty, and he values and respects that.
14Byakuya Ishigami
Father Of Senku
Fate placed astronaut Byakuya (stationed on the International Space Station) safely orbiting above when Earth turned to stone, sparing him from the petrifying cataclysm below. Returning to an ossified world, Byakuya became a father figure for humanity’s rebirth.
Am an astronaut..Earth’s last one, at that. I work for the future of science! – Byakuya, Chapter 115
Byakuya is depicted as a loving and caring father.

Before passing the torch to the next generation, Byakuya laid a trail of clues meandering through the Stone World, anticipating his prodigal son’s ingenious quest to resurrect civilization.
13Nikki Hanada
One Of the Toughest Warriors In Dr. Stone
The burly Nikki looks like she could crack stone with her bare hands – and she just might! Her formidable physique makes Nikki one of the toughest warriors in Dr. Stone. But she’s a gentle soul behind those hulking muscles. Before petrification, singer Lillian Weinberg was the reason Nikki could bear the days.

Muscle heads add something special to anime, and these are among the best of the best.
After she’s revived in the Stone World, Senku and his team use a recording of Lillian’s voice to convince Nikki and other members of Tsukasa’s Empire of Might to join the Kingdom of Science. She initially appears to be hard-headed and aggressive, but she also has a softer side, especially when it comes to things she’s passionate about, such as Lillian’s music.
12Ukyo Saionji
The Pacifist
The observant Ukyo sees far more than most - and hears even more! In the pre-Stone World, Ukyo was a sonar operator in the Self-Defense Forces, a fact that informs his unique abilities in the Stone World. He has highly developed hearing that allows him to detect sounds from great distances or even underwater, making him a highly effective scout and lookout.
Ukyo is characterized as being fairly calm and level-headed. He is also shown to be very thoughtful and dislikes unnecessary killing, even when he is part of Tsukasa’s empire. His skills and his moral stance become important factors in his decision to switch sides and join Senku.

Gifted Artisan (But Limited Character Development)

Despite her importance, Yuzuriha does not rank higher on this list due to her character development not being as well-rounded as some of her fellow cast members.
