Mozu (モズ) is one of the two strongest warriors in the Petrification Kingdom, with the other being Kirisame. He is the secondary antagonist of the Treasure Island Arc.


Mozu is a tall, spear-wielding muscular man wearing pauldrons that appear to be made of stone. He has dark dreadlocks that are tied into a low ponytail. He has facial markings of unknown origin that extend from the top of his eyebrows in a curl, to between his eyes, similar to Kirisame's.


Mozu is a cocksure and easygoing man who enjoys the company of beautiful women, and strong people. He giddily looks forward to the Harem selection every year, hoping for cute girls to appear. He becomes fascinated with Kohaku upon meeting her, due to her combination of strength and beauty, two things he appreciates greatly.

He enjoys this fun to a fault, allowing Kohaku into the harem despite her nearly breaking Minister Ibara's hand. Even in the past, he lamented having to petrify the young escaping Amarillys, recognizing how beautiful she could potentially be in the future.

Despite all this, he possesses a sharp instinct and cunning, and is hinted that he knows a lot more than he lets on.

In battle, he lives for the thrill, as seen when he fought against Hyoga who he found to be a worthy adversary. Even after being defeated, he showed him self to be a good sport and even asked his victorious opponent to give him lessons.

Abilities and Skills

Physical Abilities

Mozu is a highly competent fighter, able to easily throw aside five men (including Oarashi) with his strength alone, and was able to effortlessly overwhelm Kohaku with his skillful spearmanship (Although she was not armed with her typical weapons at the time.) He also defeated Kinro, Magma, and Nikki in one blow each. He and Kirisame are noted to be the strongest warriors of the Kingdom of Petrification.

The true depths of his strength is that he lasted against the great warrior Hyoga before he was defeated.


Mozu was able to deduce that Kohaku was one of the intruders, although he chose to withhold this information, due to his personal interests.



Mozu was able to sneak up on Senku and his friends. Even with Ukyo's superlative hearing, he snuck up on them without detection.


5 years ago, Mozu and Kirisame were on a boat and found a group of kids including Amaryllis trying to escape the island with their boat. Kirisame petrifies all the kids with her weapon but Mozu tells her to not petrify Amaryllis because of how she can be cute in the next 5 years.


Treasure Island Arc 

Mozu attends the harem selection and notices Kohaku's strength.

He later finds out Kohaku is an invader and fights her.

Mozu comes into terms with Senku of a plan to take the petrification weapon and fight Ibara. Mozu plans to dominate everyone on the island after taking the petrification weapon.

Yo tries to shoot Mozu but Yo missed and Mozu easily sweeped some of Senku's allies on the ship. Mozu and Ibara corner Senku and his allies in a room where Senku revives Hyoga.

Mozu goes on to fight Hyoga but was defeated by Hyoga when he used the Kan Style with Kinro's spear. He, along with Hyoga and everyone else (but Senku) on the island was petrified by Ibara.




At first, he wondered if Hyoga was a strong opponent. Mozu even tried to sway him into allying with him. After his offer was refused, Mozu wasted no time in engaging Hyoga. In the fight, Mozu noted Hyoga was the first warrior to get him to struggle. After Hyoga won, Mozu gave a sign of acknowledgement for his skill. When the island was being engulfed in petrifaction, Mozu and Hyoga promised if they’d be freed then they would spar again.


  • His name Mozu is the Japanese word for Bull-Headed Shrike (Bird that impales prey on thorns)[1]
