Juu Ou

Juu Ou is a lion-headed humanoid monster with a heavily muscular human body.

He serves as one of the elite combatants created by the House of Evolution.

He was described by Armored Gorilla as having a level of strength that the then-current Genos could not match.

Despite this fearsome reputation, he was effortlessly defeated by Saitama.

Juu Ou has the face and mane of a lion combined with a powerful, bodybuilder-like human physique.

His build emphasizes raw power and ferocity, fitting his role as a close-combat monster.

His combat style and confidence suggest a proud, aggressive personality.

However, against Saitama he quickly transitions from assault to panic as he realizes the massive gap in power.

Juu Ou possesses great physical strength, speed, and durability by the standards of Demon-level monsters.

He combines animal ferocity with the refined combat capabilities of a humanoid body.

His signature abilities focus on slashing attacks that combine claw strikes with powerful shockwaves.

He is also capable of unleashing these techniques at very high speed in rapid succession.

Signature Techniques

Lion Slash

Juu Ou launches shockwaves from his claws that slice the opponent from a distance.

These cutting waves allow him to attack without needing direct physical contact.

Lion Slash Rapid Barrage

This is an upgraded version of Lion Slash, in which he fires the slashing shockwaves at tremendous speed.

It creates a relentless storm of blade-like shockwaves intended to overwhelm and shred the target.

During his encounter with Saitama, Juu Ou uses his techniques in earnest.

He unleashes both Lion Slash and Lion Slash Rapid Barrage in an attempt to cut Saitama to pieces.

Saitama casually evades every single attack without taking any damage.

Juu Ou is then countered by Saitama’s move called Consecutive Normal Punches.

The barrage of punches completely pulverizes Juu Ou’s body from the waist up.

The fight ends so quickly that Juu Ou has no chance to adapt or respond.

Juu Ou’s corpse is left unattended on the battlefield after his defeat.

This discarded body later has a small but notable impact on the story’s world.

In a bonus four-panel comic in volume 3 of the collected edition, a crow is shown eating Juu Ou’s remains.

After consuming the flesh, the crow undergoes a sudden mutation, hinting that Juu Ou’s body still contains dangerous genetic or experimental properties even after death.

Juu Ou belongs to the House of Evolution, a secretive organization focused on artificial evolution and bioengineering.

Within this group, he is regarded as the second-strongest combatant, surpassed only by Asura Kabuto.

Other House of Evolution creations such as Armored Gorilla recognize his strength.

Armored Gorilla explicitly states that Genos, at that point in time, would not be able to defeat Juu Ou.
