Tsukasa Shishio (獅子王司 Shishiō Tsukasa) is the main antagonist of the first 82 chapters of Dr. Stone.
His goal is to thin out human population to create a new world without modern technology, saying that adults and how humanity evolved has caused them to become evil.
Despite his claims that no threat would come after Senku and Taiju, which became ironic, Tsukasa has shaped up to be one of the biggest obstacles to Senku's Kingdom of Science and restoring humanity as a whole in general.
Tsukasa is a tall man that has dark brown long hair reaching his lower back and dark brown eyes. His skin is pale, and he has feminine facial features despite being a male MMA fighter. A key characteristic of this is his long dark eyelashes and slender face. He has three stone markings; one across his face that cuts across his right eye, another etched deep into his left one from the corner of his eyelid all the way down across his nose and ends at the bottom of his jaw on the right, and the other being stretched across from his left shoulder over his chest and stopping at his upper abdomen.
After years of MMA fighting, Tsukasa has gained permanently swollen knuckles found on his index finger, middle finger, and ring finger. Before humanity was petrified, Tsukasa had wavy dark brown hair he’s been growing out since he was little. Post-petrification he’s kept remnants of stone on the tips of his hair.
His initial outfit starts off with a red yukata made from a lion’s remains he ended up killing to protect Senku and Taiju. He used its pelt as a coat he often wears around his shoulders. He wears no shoes. After chapter 78, he wears a cream pelt shirt with his torn yukata as a skirt.
Tsukasa is essentially violent but extremely careful and aware of his actions. He is a very kind, thoughtful, and polite man outside his pessimistic ideals towards humanity. He offers help in the beginning to Senku and Taiju after they revive him and becomes their hunter for food, using his skills as a prominent athlete to aid them. It’s revealed later that Tsukasa plans to purge humanity and thinks Senku will go along with him, but instead Senku rejects him. After this point, Tsukasa becomes fairly determined in carrying out his plans even to the point of leaving their group. He’s confessed to Senkuu he doesn’t care about anyone but himself, though in the latter half of the story it’s revealed that Tsukasa loves his sister Mirai more than anything in the world and that is where his resilience comes from so he can save her.
He also reveals that Senku could’ve been his first friend pre-petrification as to which Senkuu agrees. From this angle, we can assume Tsukasa shuts himself off from others and only focuses on saving his sister. He’s naturally withdrawn outside of his goals. He tends to hate humans who control and manipulate others. By his actions, it is possible to assume that Tsukasa hates any hierarchy or practice of power. His goal is to create a society without technological advancement and he uses any means to achieve that objective; creating his own empire modeled on his twisted views of humanity.
Though to note, there are many points in the story that exploit Tsukasa's psychotic behavior. One instance is when he first breaks a stone statue and has no remorse, continuing to crush more in his wake. He particularly goes after older adults and elderly people, but specifically leaves children alone. This can be related to his personal background and history of being assaulted and abused by those in authority. He also ends up taking Yuzuriha hostage in order to gain the Revival Formula. Tsukasa also by no means wants to resort to fighting or killing but will do so if he feels pressured or his vision for humanity is at stake. This can be shown when he ended up killing Senku after sharing a tender moment of wishing they could've met 3,700 years later.
Abilities and Skills
Tsukasa is a highly intellectual individual.
True to his epithet, Tsukasa possesses an extreme amount of strength and is an highly proficient combatant. He was able to defeat lions. He also managed to cut down a tree with one strike of his stone sword, a tree which Senku noted to weigh 1 ton. Tsukasa's speed and reflexes are also equal to his strength. When Senku fired an arrow with a crossbow, Tsukasa managed to grab the said arrow with his bare hand. Senku later noted that the crossbow fired at 200 kilometers per hour. He was also able to parry all of Kohaku's swift attacks during their battle with apparent ease.
After being freed from his petrification, Tsukasa wielded a primitive looking spear with a stone blade to hunt for fish with it. The hilt broke partially later on, effectively making the weapon into a sword. He appears to be highly skilled in wielding it during combat. The stone sword is sturdy enough to cut wood with it.
When he was younger, Tsukasa was picking out seashells on the beach to make a necklace for his sister Mirai because she wanted to be a princess like Ariel in the Little Mermaid (1989). At this time his sister was clinically confirmed to be brain dead. In the event of him choosing seashells, an old, drunk, fisherman comes and beats Tsukasa to the point his face was unrecognizable. The fisherman justifies his assault behind him owning a fishing permit in the area and Tsukasa was trespassing. From then on, Tsukasa somehow managed to train and find his way to the MMA so he could support his sister's life and defend himself by all means. He ends on becoming a well known MMA fighter nicknamed the "Strongest Highschool Primate" in the combat sport.
