After a lengthy battle, both parties are wounded, but Godzilla still remains fierce and raging. Gamera flies towards him, seemingly to crash into him, but instead he grabs Godzilla and flies with him high into the atmosphere and finally through the stratosphere into naked space. Godzilla keeps fighting all the way, charging up an almighty atomic breath blast, but just as he lets loose, so does Gamera, and both warriors are destroyed in a conflagration that turns night to day across half the planet.
In the aftermath, the UN declares that such a thing must never happen again, and resolves that humanity has to advance to a state where it can live in harmony with the world. The avatar-hero who got burned by Godzilla's avatar is in a hospital bed, expected to never fully recover, but he suddenly wakes up, his wounds healed, without even scar tissue. We see a butterfly slowly opening its wings on the window sill.
Meanwhile, the girl who had been possessed by Godzilla's spirit is in a Silence of the Lambs-type cell: her eyes are still yellow reptilian eyes, and her only line in this state in the movie is a growling "This is not over yet" to her parents.
Post-credits scene: a team of archeologists is at work in the temple, and one of the professors is excitedly at work on the ruined altar. He holds up a single golden scale, and says he has identified the name of the fourth deity. He starts to say "G- " and the camera pans to outer space, far, far, far away into the depths of a distant, horrifying planet, where deep in a cave a single eye opens menacingly. Fade to black. The end?
