Remember what apen with Kevin after Godzilla: King of the Monsters? Well, the director Michael Dougherty says this:

"That wasn't a direct set up of Mecha-King Ghidorah, no. I'm not saying it's not, but if you think about King Ghidorah and what's he capable of, regeneration being a key one and the ability to call the other Titans, he's a gold mine of opportunity. That DNA is an untapped resource as far as Charles Dance's character is concerned. A few scrapings of cells and who knows what you can create with it!"

This create 3 options.

1. Ghidorah will return has a Mecha/Cyber-Ghidorah

2. We will see a new Titan with Ghidorah DNA

3. In some part of the movie, Kong will recive Ghidorah's DNA so he can strike back Godzilla.

The third option should be very logic. if you are gona fight with Godzilla, you should need some extra power, like regeneration, so as not to die at the first atomic breath.

Michael also say this:

"Originally, we were going to have two post-credits scenes. There's the one we shot with Charles Dance buying King Ghidorah's head but there's a second one that we had written, boarded, and even had the locations scouted out and costumes ready to go. It basically involed Zhang Ziyi's character and it's set in the aftermath of the film. She's in Tokyo and goes into some sort of restaurant or bar and goes down a set of stairs and ends up in what looks like an ancient temple that is eerily similar to the one we saw at the beginning of the film in China.

"Then, she meets up with her identical twin sister and the twin sister is expressing her concerns about whether they should go through with this or not, that these girls are so young, and they're not sure if they're ready. Ziyi says, 'So were we once' and they emerge into this giant chamber where we reveal a second Mothra egg and in front of that are two little girls, maybe three or four years old, also identical twins and they're singing the Mothra song to the egg to get it to hatch. I was heartbroken that we didn't get to shoot that because it would have confirmed that she was playing the Mothra twins which is a deep cut reference from the original films."

"second Mothra egg" ...Oh yeah, Mothra will come back, but, why it's in Tokyo? We don't know exactly why, but that means that Tokyo will be a important place in the movie.

We also can know that Zhang Ziyi got a twin and 2 little twin sisters, that maybe, will have a connection with the second Mothra, like the Mothra twins in the old Toho movies.

And that's all, remember : March 2020
