Hollow Earth is Kong's home. „ 

Nathan Lind

The Hollow Earth, known to the Iwi as the Long Ago Below[1], is a location that was discovered in the 2019 film Godzilla: King of the Monsters.

It is an ancient subterranean ecosystem deep within the Earth, close to the planet's core. Its gravity is unique and inverts at a halfway point, allowing Titans to walk freely on both floor and ceiling of the Hollow Earth without fear of falling from one to the other. It's surrounded by a gravitational-electrostatic "membrane" anomaly inside the Earth's mantle[1]. The ecosystem continually radiates radioactive energy, allowing the creatures that inhabit it to evolve to titanic sizes. A fortress belonging to Kong's species also exists there, with a throne once held by his ancestors.



The Hollow Earth is believed to be the natural habitat and evolutionary place of origin of all Titans. In ancient times, Kong's species warred against Godzilla and/or a member of his species for dominance within the Hollow Earth. Iwi legends suggest that the war ended with Titanus Gojira's victory and with the Kongs, and the Iwi who'd originally lived alongside them in the Hollow Earth, being banished to Skull Island on the surface world[1].

Godzilla: King of the Monsters

After nearly being killed by the Oxygen Destroyer, Godzilla retreats to his temple located within the Hollow Earth to rest and regenerate. A Monarch expedition team follows the Titan in, confirming the organization's theories of an entire world located beneath the surface. Ishiro Serizawa detonates a nuclear warhead in Godzilla's temple, effectively reviving him but destroying the temple and the surrounding area.

Though the Hollow Earth itself doesn't appear in the comic, a Genitor swarm emerges from a Hollow Earth breach in Godzilla's old lair, that was opened by the bomb that Ishiro Serizawa used to heal him. After Godzilla defeats the swarm, he fires his atomic breath into the hole, sealing it shut and preventing any more swarms from escaping to the surface.

A joint expedition team of Monarch and Apex Cybernetics use three HEAVs to follow Kong into the Hollow Earth in order to find and secure an energy source capable of subduing Godzilla, using the ape as a sort of navigator. Those who have been watching over Kong at Skull Island, including Nathan Lind, Ilene Andrews and Jia, are brought along on the expedition, but the true purpose of the journey is hidden from them.

Kong explores Hollow Earth at a rapid pace before stumbling across an ancient fortress built by his ancestors. He enters the structure, claiming an ancient axe nearby a unidentified titan's corpse. The group observes Kong and realizes that he is home there. At this point, Maia Simmons of Apex orders the extraction of the ancient energy radiating from the ground, directly from the planet's core. After angering Kong, Simmons and the rest of her team are killed, but not before the energy is sent back to the Apex facility in Hong Kong and used to power Mechagodzilla.

After destroying Mechagodzilla and resolving his now ending rivalry with Godzilla, Kong decides to return to the Hollow Earth, making it his new home.

To be added...


  • The idea of a hollow earth in a Godzilla film is in fact an old one and would have appeared in the cancelled Godzilla film Bride of Godzilla.
  • In Godzilla vs. Kong - The Official Movie Novelization:
    • It's heavily implied that the Hollow Earth is the source of global myths and legends about people emerging from the earth, due to Titans and the Iwi having lived there at one time before coming to the surface world.
      • Nathan Lind at one point speculates that life on Earth originally evolved in the Hollow Earth rather than on the surface, and that it's where life survived and recuperated after every mass extinction before returning to the surface. He also speculates that humanity's hominid ancestors might have really originated there.
    • The Vile Vortex is explained to be a space-time distortion when Nathan Lind, Ilene Andrews, and Jia escape the hole Godzilla made. [2]
    • The Vile Vortex in Antarctica is located only a few miles from the site where Ghidorah was originally frozen, although the ice on the vortex entrance is thirty-million years old and is older than the ice encasing Ghidorah, and it's implied to be no coincidence that Ghidorah was frozen so close to the entrance.
