The Sky King (天空王, Tenkūō) is a Mysterious Being who rules the skies and wants to take Earth for himself.


The Sky King was a humanoid birdlike being with the appearance of an aging, but very muscular old man. He has long hair, a large nose, wrinkled forehead, sharp teeth and pointed ears. He has two sets of wings on his back as well as talons on his feet and clawed fingers. He also appears to wear a small crown. His overall appearance is reminiscent to the traditional Japanese Tengu.[1]


The Sky King appears to be cruel and rather arrogant, due to his belief that he could destroy the Hero Association with ease, or at least extremely confident in his power and that of his warriors. He coveted to conquer the Earth's surface.


Hero Association SagaEdit

Alien Conquerors ArcEdit

After seeing the Deep Sea King and the Subterranean King perish, he decides he wants to take over the world himself with his four underlings: Hawk, Kite, Eagle, and Falcon.[2] However, all four of them are killed by an unseen enemy. Before he could do anything, he perished at the hands of Melzargard who treated him like a 'small bug'.[3]

Abilities and PowersEdit

Due to being the ruler of the Sky folk, he is on par with other kings. It can be said that he is rather strong considering he was able to jar the Hero Association headquarters. Along with his own powers, he has a group of underlings that obey his every command and all bear the name of birds.[4]

Physical AbilitiesEdit

Flight: The feathered wings sprouting from his back allowed the Sky King to fly in midair.

Energy Projection: The Sky King has been shown to be able to direct blasts of energy from his mouth.[5]
