The Ancient King (古代王, Kodaiō) was the king of the Terror Lizard Clan.


The Ancient King is a colossal, loosely humanoid creature that has various animalistic features, such as scales, horns, claws, and a reptilian tail.


The Ancient King is a ferocious and violent being who wishes to take the surface of the Earth for his race, much like the majority of the other "kings".


Hero Association SagaEdit

Alien Conquerors ArcEdit

The Ancient King awakens after 300,000,000 years of slumber, which was used to wait for the other kings to be taken out. He is attacked by military forces, but the missiles are proven ineffective against the Terror Lizard's skin. The Hero Association deploy Tatsumaki to take care of the threat.[1]

After briefly conversing with Tatsumaki, he's killed by her, after getting smashed by a meteor brought from space by Tatsumaki with the use of her telekinetic powers.

Abilities and PowersEdit

Not much was seen of his abilities, due to how quickly Tatsumaki disposed of him, however it can be assumed that his strength and endurance are tremendous.

Physical AbilitiesEdit

Immense Strength: The Ancient King easily bursts out of a mountain and it's safe to assume by its size alone that it's capable of causing a lot of damage.

Immense Durability: The Ancient King is seen easily enduring military missiles and also comments it would require something like a "meteor" to kill him, giving him amazing durability.

Energy Projection: He seems to have the ability to charge energy beams from his mouth.
