Beast King

Beast King (獣王 Kemono-ō) is an artificial mutant created by Dr. Genus of the House of Evolution. Beast King is the leader of Dr. Genus' strike force and second-strongest specimen in the House of Evolution, exceeded only by Asura Rhino.

Appearance
Beast King is a large, humanoid lion, with a full mane and tail. In spite of his humanoid, five-digit hands, he still wields sharp claws on his fingers and padded, four-toed feet.

He wears a black shirt, animal furs on his shoulders, and a leopard-skin cloth around his waist, secured by heavy chains and a belt with a lion-head buckle. There are bracelets on both his wrists and ankles, and bracers on both biceps, which he breaks and shatters once enraged.

Personality
Beast King speaks very loudly, roaring and shouting his dialogue constantly. Although only the second-strongest, Beast King revels in his own power, and becomes increasingly frustrated with Saitama's inexplicable strength and absence of fear.

As a leader, he is sadistic and has little regard for his fellow mutants, dismissing his killings of Slugerous and Frog Man as the 'law of the jungle'.

House of Evolution Arc
After witnessing Saitama instantly kill Mosquito Girl, Dr. Genus takes great interest in him as a human specimen, and sends Beast King, Armored Gorilla, Manty, Ground Dragon, Frog Man, and Slugerous to abduct him for further research.



Saitama defeats Manty, Frog Man, and Slugerous in a failed ambush, but is grabbed and rooted in concrete by Ground Dragon. While Armored Gorilla repels Genos, Beast King taunts Saitama, threatening to scratch out his eyes. Nonplussed, Saitama casually frees himself, sending Beast King into a limb-cutting frenzy. He manages to accidentally kill Slugerous and Frog Man, but even after augmenting his strength, he is disemboweled by a flurry of punches from Saitama.

Beast King's death prompts Ground Dragon to flee and shatters Armored Gorilla's confidence, thus bargaining with Genos and Saitama for his life.

Some time after his death, a flock of birds descend to pick at his entrails, causing them to sprout arms and become ravenous.

Abilities
 Despite not harming Saitama, Beast King demonstrates immense strength, chiefly through murdering his teammates and inflicting massive collateral damage.

Limb Cutter: Beast King's claws are capable of cutting through stone and flesh across considerable distances, demolishing entire buildings in a single swipe.

Transformation: When enraged, Beast King gains considerable muscle mass, tearing through his clothing and ornaments. In this state, he loses all self-restraint, ignoring Dr. Genus' orders and harming his own allies.
