Fan Casting Godzilla: The Star-Eater

The Iwi legends tell of an catastrophic event where a Godzilla ate a star that crashed to Hollow Earth and went out of control, the origins of Godzilla's atomic breath. Godzilla dives into the Hollow Earth to find the star crash-site from eons long past. Along with him is his new adopted son named Minya, and a giant ankylosaurus named Anguirus. Could Godzilla be the one to eat that star or was there another? Is Godzilla evil or was the star he ate for a good reason?
