How would you do King Ghidorah's origin?

I would approach Ghidorah in a way that is vague but still keeps him true to his origins. The most popular origin for Ghidorah is an alien creature that destroys entire worlds. Legendary made Godzilla's origin more plausible by making him a giant prehistoric creature that remained hidden deep underwater for eons. They never explained how he evolved to such a huge size or how he is able to metabolize radiation, he just does. The same idea could work for Ghidorah. Either he arrives from space mysteriously or emerges from some crevice deep in the Earth and lays waste to the planet for no logical reason. Humanity would be baffled by the appearance of such a strange creature and its chaotic destructive tendencies. Godzilla would be forced to do battle with Ghidorah to protect the natural order of the world and possibly even have to team up with Mothra and Rodan to stop him. This way, there is no need to explain some far-fetched evolution for such a creature or just copy-and-paste Godzilla and M.U.T.O.'s origins. Plus, keeping his seemingly extraterrestrial origin vague would prevent Ghidorah falling under the cheesy alien invader archetype.

yosemite mt he's what stopped it from blowing up

Someone around here had the idea that he was inside the asteroid that brought about the end of the dinosaurs (or some other era). Afterward his presence on Earth, dormant or otherwise, would bring on the many Asian legends of god-like dragons and serpents.

This would keep his extraterrestrial origins intact and vague while also linking him to Earth's history. I think it's rather brilliant. We wouldn't need any more than that.

^ That's probably the best way to go.

I would make KG's origin kind a like his origin from RoM3

I just want him to be from space, besides that I'm not sure

It just depends on which Incarnation origin! Showa = Space, Hesisei and GMK = Earth

@GMAN, I thought of that, but then it raises the question of just how on earth did he end up in there in the first place (no pun intended).

If they really wanted to go the "grounded" approach, I think three snake-evolved radioactive creatures conjoining (a la the Dorats approach in GvKG) after being sent into space would make the most sense, but that's just my opinion. Snakes and dragons look almost exactly alike, just Google some pics of the two, you can barely tell the two apart, and since dragons are fantasy/mythical creatures that don't exist IRL, they would have to go the evolution route if audiences were to buy that a dragon of any kind actually existed on this earth at any point in time (whether it originated there or not), especially a three-headed one. Plus, it's been said around here that they hope the humans find Ghidorah buried on the moon at some point, that would explain how he wound up there.

Honestly, the mutation angle works LESS for this "grounded" approach. This new universe doesn't play around with mutation like the Heisei series did. It's a well-known fact that organisms can arrive on different planets by way of asteroids. It's also well-known that the more adaptable the organism, the more likely it is to survive. It's also a well-known fact that Kaiju are highly adaptable creatures. It's also a well-known fact that different living conditions result in different physiological variation

Suddenly, an ancient evolved non-Earth-based organism like King Ghidorah isn't sounding so farfetched in comparison. The idea of any sort of creatures becoming conjoined by way of mutation is somewhat farfetched when it comes to a functioning animal. ON EARTH. Other living conditions elsewhere are allowed to produce totally different results without abiding by Earth-based evolution because the conditions for life are totally different.

I agree with Gman2887. The idea of King Ghidorah being the meteor that caused a prehistoric extinction not only invokes his origin as a world destroyer from the Showa series, but being the cause of the extinction of the dinosaurs in Rebirth of Mothra III. Plus it makes him a perfect anithesis to this version of Godzilla: an indiscriminate chaotic engine of destruction and death. It also ties him to the history of Earth like Godzilla and avoids the need to come up with a complicated unrealistic explanation for Ghidorah that would also upset fans.

What the Awesome Gman, and The King of the Monster said.

Yeah I agree with TheGman123, I'm not feeling the mutation angle. The whole snakes mutation thing sounds like something better saved for a Sharktopus sequel. Plus it falls victim to the overexplaining of the Heisei series. Things like that aren't necessarily grounded, it just feels like over reaching.

Besides, nothing in the Legendary movie has hinted at mutations. There's a love for naturalism which was highly embraced by early Showa monsters. A sense of less explaination and a simple dropping of these lifeforms into our world. (They lived here millions of years ago and have awakened.)

Meanwhile, King Ghidorah never really had an explained origin in the Showa series and that worked just fine. I think some vague links to space with no definite answer to his genesis are far more mysterious and give King Ghidorah a hint of unexplained creepiness.

@TheGMan: if you're talking about the evolution of the 3 creatures to be conjoined (the Hydras in my idea), it's no more "ungrounded" than Godzilla mutating and growing by absorbing nuclear radiation because, guess what? That's how LegendaryGoji came to be in this "grounded" universe, it follows that exact same formula. Plus, my origin idea explains how he gained his cosmic and gravity-based powers in the first place. A three-headed golden dragon that can shoot lightning from his mouths "just because"? Not buying it. They at least offered an explanation for how LegendaryGoji is able to shoot nuclear plasma from his mouth in G14, even though it also isn't realistic in any way.

Plus, how can a creature literally be born inside of an asteroid (as in, originate there)? I'll admit, I'm no scientific or evolution expert or anything, I've said this in the past, but I'm just not feeling it as far as realism is concerned.

Conjoining after birth is unheard of on Earth. And being sent into space? HOW? By Humans? Well, then he doesn't have enough time to truly be able to become a monster by the rules set by the Legendary universe. By the way, the Legendary Godzilla doesn't mutate. His species, and several others, evolved to specifically feed off of radiation. No mention of mutation whatsoever.

And I said arriving in an asteroid. I never said being born inside one. It's more of a situation where the species hitches rides on asteroids to new planets, like how parasites hitch rides on larger animals to arrive in new areas to grow and breed. Please pay closer attention to what I actually said. I'm VERY SPECIFIC when I say something.

Another thing, creatures that naturally suffer from polycephaly, i.e: naturally born with three-heads tend to not have a long life force, or have a hard time moving and operating all 3 heads, or some other deformities in them, as in, they're not all symmetrical, not all the same size, whatever. At least this way, they could all feasibly be the same size and all actually work. Since he consumed dark matter, or cosmic energy, whatever, while in space, and is not one entity, but several conjoined ones, that could reasonably allow him to anatomatically sustain and operate all 3 heads and have a long life force when he otherwise couldn't. It also explains him being able to shoot lightning from his mouth, there's that, too.

A three-headed golden space dragon born with an extremely rare condition and an even rarer lack of deformities from said conditition and can inexplicably shoot lightning from all 3 mouths and fly through the vacuum of space is the furthest thing from realistic there is out there. My idea at least offers a plot device that would allow him to bend these rules a little bit, i.e: absorbing cosmic/dark energy from space, the same plot device that enables Godzilla to breath plasma (energy consumption/absorption). It would also explain how he's able to move through the completely airless depths of outer space, since it gave him gravitational/magnetic powers. They could say he gives off gravitational/magnetic force energy or whatever as a result of this energy source to do it.

In other galaxies, creatures could follow different evolutionary patterns. While Godzilla evolved to be 355 feet tall, feed on radiation, have rows of giant spikes on his back, and spit an atomic heat beam, and alien reptile could have evolved over time to have three heads, fly in the vacuum of space, and naturally harness electrical powers with no explanation. Having snakes get shot into space and absorb cosmic energies and then mutate and come back to Earth and all this other stuff is way to complicated and sounds even more sci-fi-ish than just making Ghidorah an alien of unknown origins. This would be like making Godzilla a mutated dinosaur like in the Heisei series instead of the evolved ancient creature that he is. Gareth chose to go with vague mysterious origins that allowed Godzilla and M.U.T.O. to fit his vision in a way that did not beg further explanation or blatantly challenge realism. The same should go with King Ghidorah.

Not exactly, either. The thing is that, being a non-Earth-originated lifeform affords conditions to develop in that don't constrain certain physiological differences and variation. No amount of true science can explain King Ghidorah, just like the other creatures.

Not even Legendary Goji's plasma breath was thoroughly explained, just that he can access his radiation reserves to create and wield it. Becoming conjoined by way of cosmic radiation doesn't make much more sense, since it still means space is creating non-Earth conditions, but is basically retreading Heisei territory, which most people don't prefer as the origin of King Ghidorah.

We're not just talking about the explanations. We're talking about what's already been established, what's been seen so far in the Legendary universe. Conjoining by way of cosmic conditions is no more grounded than a creature simply evolving that way through cosmic conditions, but at least evolving that way fits in line with the groundwork already established in the Legendary universe.

I would comment but i do believe that the king of monsters, and Gman2887 have pretty much said what i would have said.

I kind of like his origin in GMK, but that wouldn't really work in the legendary universe.

^I wouldn't think so either. He has to arrive from space. It would make alot of fans happy to know that he is coming from space.
