Headscratchers / Godzilla vs. SpaceGodzilla

• Why did the Shobijin even bother warning Miki about SpaceGodzilla at all? It ultimately had no bearing on the plot of the film; everyone already knew or at least suspected that some horrifying space monster was on its way to Earth. And sure, it was difficult, but it was a situation that Godzilla and G-Force ultimately dealt with on their own.
  • Out of plain concern, most likely. She's their friend, they want to make sure she knows and can do something to protect herself, and anyone else she's able to help. Although the more cynical, real world version is that Mothra was immensely popular at the time, so including her in the movie, in a cuddly, marketable fairy version to boot, would lead to boosts in tickets and toy sales.
  • There's also an Epileptic Tree that claims Miki hallucinated the whole thing.
