Godzilla and King Kong certainly aren’t the only Titans popping up in the next MonsterVerse movie, and should they indeed end up joining forces to fight a different threat, having Mothra by their side would certainly be welcome.
Nevertheless, while Godzilla: King of the Monsters wasn’t able to officially introduce the Mothra twins, Godzilla vs. Kong will do so, perhaps signifying that at some point during the movie, the new Mothra will enter the picture.
On the other hand, maybe the second Mothra’s emergence will be saved for a future MonsterVerse movie, and the new twins’ appearance in Godzilla vs. Kong will simply remind audiences that we shouldn’t forget about her.
It’s already been confirmed that Zhang Ziyi will reprise Ilene Chen in Godzilla vs. Kong, though there’s no word about if Ling Chen will appear.
