The Subterranean King (地底王, Chitēō) was the king of the Subterranean People. He led his people from below the surface to conquer the area on it. He was quickly defeated by Saitama.

Like the Subterranean People, the Subterranean King had a humanoid appearance, but was about double the size of a regular human being. He was covered with black, armor-like pieces, with blue lava running in the space between them. He has three, sharp eyes and four arms, all with only three fingers. For each one of his arms, he carried a magma blade of blue color.

In the manga, his armor is brown in coloration with yellow/reddish magma swimming through its body which matches the common known colors of an active volcano. His blades also have the same color of magma.


The Subterranean King seemed to be rather confident in his abilities, but was defeated almost instantly.

Statue of Subterranean King

Saitama has a dream where he is attacked by the Subterranean People, and after a hard battle where he defeats them all the Subterranean King shows up for one last fight. Right before they start to fight, Saitama's dream ends. Upon waking up Saitama notices that the Subterraneans truly have shown up, and leaps at a chance to fight them. However, when the Subterranean King does show up he is defeated instantly and his people surrender and scamper back underground.[2]

Monster Association Arc Edit

During the fight between Child Emperor and the resurrected Phoenix Man, a statue of the Subterranean King is seen, along with two centipedes encircled around him. His people are also revealed to have been killed by the Monster Association.

Abilities and PowersEdit

Nothing is known of the Subterranean King's powers due to his quick death but it is presumed that he is a skilled swordsman. He is on the same level as the Deep Sea King and the Sky King.[3] He was the ruler of an army of powerful subterranean Mysterious Beings (but still, no match for Saitama).

Fighting StyleEdit

Swordsman: Given his choice of weapons, the Subterranean King likely has some swordsmanship skills. It is unknown how skilled he actually is, due to his quick death at the hands of Saitama.


Swords: The Subterranean King carries four very large flaming swords, one for each arm. His swords emit powerful heat like lava and each cleave cuts and burns his enemy.[1]
