Tsukasa Shishio (獅子王司 Shishiō Tsukasa) is the primary antagonist of the first 82 chapters of Dr. Stone.

His goal is to thin out the human population to create a new world without modern technology, saying that adults and how humanity evolved caused them to become evil.

Despite his claims that no threat would come after Senku and Taiju, which proved ironic[3], Tsukasa became one of the biggest obstacles to Senku's Kingdom of Science and restoring humanity as a whole in general.

Appearance

Tsukasa is a tall and muscular young man with brown hair and pale skin. His height is estimated to be somewhere around 6'8". He is stated by Boichi that he's the tallest out of the cast.

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 gained permanently swollen knuckles found on his index finger, middle finger, and ring finger. Before humanity was petrified, Tsukasa had unruly hair he’s been growing out since he was little. Post-petrification, he’s kept remnants of stone on the tips of his hair and has a shaved undercut with a slit at the sides, complimenting his stone markings across his eyes.

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 that he wore around or draped across his shoulders. He wears no shoes. After chapter 78, he wears a cream pelt shirt with his torn yukata as a skirt.

Personality

Tsukasa is essentially violent but extremely careful and aware of his actions. He is a very kind, thoughtful, and polite man outside of 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 Senku that 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 Senku 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 explore 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 is seen when he ended up killing Senku after sharing a tender moment of wishing they could've met 3,700 years later.

Abilities and Skills

According to Taiju, Tsukasa has the reputation as "The Strongest High School Primate" due to his tremendous fighting abilities. The translators note that Shishiou Tsukasa means Lion Ruler.[4][5]

Intelligence

Tsukasa is a highly intellectual individual. After Senku, it's confirmed by Riichiro Inagaki that Tsukasa would have the highest grades and ties with Chrome in a school setting. Tsukasa also states that Senkuu is the only man he has met that is smarter than him by massive inquiring levels. From this, it's assumed that Tsukasa has spent most of his life alienated from social customs because of his prime intelligence (feeling that no one would understand him) and current predicament with his clinically brain dead sister, Mirai.

Physical Abilities

Tsukasa cuts down a tree with his stone sword.

True to his epithet, Tsukasa possesses an extreme amount of strength. He was able to kill the leader of a pride of lions with a single punch, scaring the rest of the pride off.[6] He also managed to cut down a tree with a single strike from his stone sword, a tree which Senku noted to weigh 1 ton.

Tsukasa's speed and reflexes are equally extreme. When Senku shot a crossbow bolt at Tsukasa, he simply caught the bolt with his bare hand, with Senku later noting that the bolts moved at 200 km/h. He was also able to easily parry all of Kohaku's swift attacks during their quick scuffle.

In addition to his enormous strength, speed and reflexes, Tsukasa is also a tremendously skilled fighter, as he had dominated the UFC while only in high school, and remained undefeated. Tsukasa's fighting style appears to be similar to Muay Thai (kickboxing) demonstrating techniques such as the Flying Knee, Roundhouse Kick, but also spinning back Kicks from Taekwondo. As a mixed martial artist, It could be inferred that he had mastered many forms of martial arts. Even when mortally wounded, he was able to fight off the spear-wielding Hyoga. He also shows that he is an able swordsman as well, wielding his stone blade with ease.

Equipment

After being freed from his petrification, Tsukasa began wielding a primitive-looking spear with a stone blade to hunt for fish. The shaft broke partially later on, effectively turning the spear into a sword. The stone blade is sturdy enough to cut through trees.

History

When he was younger, Tsukasa was at a beach collecting seashells with the goal of making a necklace consisting of shells so that he could give them to his younger unwell sister, as she loved tales of mermaid princesses.[7]

While choosing seashells for Mirai, an old drunk fisherman came and beat 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. After this event, Tsukasa's sister became clinically brain dead, and required constant life support. 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. He becomes so famous that even Taiju, who doesn't watch TV, knows who he is.
