Lets think real here folks

Well, how would YOU explain a three-headed gigantic flying golden dragon with two tails and can shoot lightning from its mouth in this "grounded" sense? o3o

to be honest i dont really care where he comes from as long as he keeps most of his core traits and hes a formitable apponent for godzilla

Making Ghidorah extraterrestrial would not ruin the realism, but making him the pawn of alien overlords might. If Ghidorah were a creature that came from space and began to ravage the planet for no apparent reason, I see no reason why that wouldn't fit in Gareth's grounded universe. There is no better way to explain a three headed, lightning spitting, golden dragon, so why not just leave his background and intentions ambiguous and only propose that he is not of this Earth?

Yeha, none of that "under orders from the galactic whatever" stuff, only pure, solo space dragon goodness! Though, why he'd come to Earth is the question, then.

I could see them portraying Ghidorah similar to how he is portrayed in Ghidorah, the Three-Headed Monster and Rebirth of Mothra 3. In those movies, Ghidorah is an independent malicious creature that comes to Earth with the sole motivation to kill and destroy. That would be a plausible explanation in the more grounded Legendary universe thna Ghidorah being the pawn of alien invaders.

Preety much agree with King of the Monsters, besides as longs as there are no Xaliens or Hunter Nenulans its not that SubRealistic for him to not be from earth

Some traits to these monsters have to stay the same like Mothra for instance. The second you take away her spiritual, deity side it's just a moth. With Ghidorah I'd keep the space angle. I'd say scientists use a machine to emulate the Muto's frequencies to try and lure Godzilla but it's amplified so much that it attracts a creature from space.

Keeping grounded means jacksquat, look at Star trek, star wars and all that stuff, even look at planet of the apes. Those storys make no sense and involve things that couldnt possibly happen, but they make hundreds of millions of dollars!

Infact making ghidorah a spcae monster would probably make people enjoy the film, it also shows that they arent taking themselves super super seriously.

Also the whole, we dont know where he came from its just from space gives a eerie and suspensefull feel to the film.

Do you freaking expect a 800 foot 3 headed dragon to be wandering around earth?

Thank you so muchGojira 2014! I was so mad everyone say this. It's sad to know everyone gonna hate the sequel since he is gonna be a earth monster.

Btw, Ghidorah came from earth before twice actually. Hesiei and GMK. So he is probably gonna be from earth. He might be part snake 

Gorilla - 800ft.?

Just saying, but "real" and "Godzilla" do not belong in the same sentence. Like amost any movie, if it was realistic, it'd be pretty lame. 

Ghidorah being from space isn't that unrealistic. I remember taking Astronomy freshmen year at college and my professor said it's literally statistically impossible that this is the only planet with life.

There's nothing wrong with him being a space monster. It actually makes the movie much more interesting rather than giving very single monster in this series the same exact background as "ancient monster that feeds on radiation". Realistic means something's taken and presented in a way that's believable. It doesn't mean if it literally can't happen tomorrow it's not realistic, if so nothing in these movies are realistic and then there's no point in not making him a space monster since they failed at the realism anyway. 

I don't care where he comes from, as long as he's awesome. :P

It's boring to have the same origon to

HFTT technecly the heisei and millenium versions are more unrealistic, beeing that in the heisei he whas 3 bio-eangeniered pets brougth by timetravelers then mutated by radiation into a 3 headed 2 tailed winged monster, and the GMK version whas an ancient guardian of japan

Plus a spirit

Yea but JRR he still had a earth orgin

If anything, being from space explains away just about every aspect of the golden emperor, from his three heads and two tails, to his ability to fly despite being so large, and to his ability to shoot what essentially amounts to lightning from his mouth.

Why not wait until they release trailers? It's ok to specualte, but at the end of the day i think we all know that ghidorah is coming from space.

I'm sorry but it's just silly. A lot of people said pacific rim had a silly tone because aliens and robots
