Idk what with the villain, but I think the "supernova" - this is a hint that Godzilla is coming to its final stage.

I think gigan, megalon, spaceg

^^This doesn’t make any sense.

^Also why Megalon?

^^^ is bro dumb??

Supernova Godzilla when?

Other: Another new original kaiju

^Yes. Highly unlikely they'll pay a truckload for some Toho monster that only fans would recognize.

I don't very sure,it would be Space Godzilla.There are a lot more chances to appear of Destroyah,cause the title of the film refers to outer space, which means that the main antagonist will be related to outer space, and it is also the most colorful alien from TOHO, and before that there were already prerequisites that he could appear in this series of films.But SpaceGodzilla is not completely excluded, because fans really want it, and it would be a shame not to listen to their opinion.

Spacegodzilla (as the main villain), Gigan & Orga or a new original MV extraterrestrial titan

SpaceGodzilla is ruined because of you brainlet Godzilla Fans Btw, Its not Gonna be spaceGodzilla Nor Destoroyah
