Mothra was always planned for "Godzilla x Kong: The New Empire," but in case there was no guarantee a new monster was designed as backup.

On the day of "Godzilla x Kong" getting delayed, Mothra is being talked about again. Could the Queen of the Monsters be returning?

If you follow the Toho_Godzilla account on Twitter, you would notice that something a little unusual is happening.

So we have seen Mothra, Rodan, King Ghidorah, and soon, MechaGodzilla, in the Monsterverse and it begs to wonder what else could appear.
