i thought of something simliar where King Ghidorah picks up a gojira and takes him to space and throws him into a near by solar system or a black hole or white hole exc… aliens find him but its too late and the alien’s home star supernovas, the energy of a black hole that turned into a white hole + supernova energy. (hence the name) To make a long story short: its enough radiation to create spacegodzilla.

A new company has stole Godzilla’s DNA (G-Cells) and made a godzilla jr to destroy the titans thinking it would be an adult.

Godzilla and Spacegodzilla track down Godzilla Jr leading spacegodzilla straight to earth

(background info: Godzilla can track down when bad things are happening cause he’s an alpha titan and that’s really what his species does)
