1.) Historical Perspective: The Earth is thought to have been through five major ice ages, and within ice ages, periods of extreme coolness known as "glacial periods." In most of his Toho iterations, Ghidorah is billed as a world-destroyer -- often the alpha monster of the universe, capable of turning healthy ecosystems into wastelands. We also know that in the MonsterVerse, major world events have been linked to kaiju: The Spanish War, if I'm not mistaken, may have been caused by Godzilla emerging from his slumber and attacking ships. It is reasonable, then, that Ghidorah may have perpetuated the conditions for ice ages or glacial periods to occur.
2.) Natural Habitat: I've heard the idea that Ghidorah is in a prison, of sorts: encapsulated in ice in Antarctica. But why does it have to be a prison? Clearly, Godzilla, Mothra and Rodan are able to enter extremely long states of hibernation/inactivity (which in Ghidorah's case may also explain why the Earth in not always in the midst of a glacial period), so Ghidorah should have such abilities as well. Indeed, in my scenario, ice is his natural, safe environment.
3.) Differentiation: Opinions on Shin Godzilla may differ -- I thought it was an eclectic, thought-provoking, but ultimately uneven movie -- but the city destruction scene should have near-unanimous support. It was AWESOME.. from the nuclear blast of the initial hit to the slicing cut through the city's skyline. It was SO awesome, in fact, that Ghidorah's gravity beams just might not cut it in terms of magnitude. Sure, 95% of the audience of KotM probably doesn't even know of Shin Godzilla, but that's not the point -- the point is, it's been done before. Heck, Independence Day 20-some years ago might never be truly topped. Imagine, if you will, Ghidorah having a G'54-type mist breath, but much stronger and expanding, covering an entire city in ice. Then, Ghidorah airs his wings and the whole city shatters, Terminator 2-style.
4.) Popular Convention: Ice dragons, or variations of, are just kinda "in" right now. Obviously, they're important to GoT lore (not just the undead dragon -- there are actual ice dragons in GoT canon).
5.) Rodan: Rodan, to the best of anyone's knowledge, appears to be hibernating in a volcano. If Rodan is to be fire-based, perhaps having some wyvern-like qualities himself, he could be more of a natural adversary to Ghidorah, versus a third wheel. Perhaps it's not Rodan and Godzilla that first find and fight each other like in The Three-Headed Monster, but perhaps Ghidorah emerges first, defeating Godzilla in a thick layer of ice, leading Monarch to make a desperate move by awakening Rodan and Mothra as humanity's only hope until they find a way to resuscitate Godzilla?
6.) Precedent: There's a pretty good front page article on how Anguirus almost made it into All Monsters Attack as an ice monster, would have been really neat.
7.) A Nod to the Past: Changing Ghidorah to more of an ice-based monster could be chance to give a nice nod to one of my personal favorites: Space Godzilla (or as I think of him after seeing Shin: Third-Form Biollante
). Maybe mix the gold with some dark blue, or even switch it up entirely and give him dark blue scales with gold eyes/horns. Similar to Space G's icicle shoulder pads, maybe give Ghidorah some ice ridges alone his mane or back for definition.8.) The Balance of Nature: I would love to see Ghidorah connected with Charles Dance's character. Perhaps Dance feels as though Godzilla's emergence is a sign of humanity's unsustainable culture, but that Godzilla, being rather apathetic towards humans, is the problem rather than the solution. He sees the environmental dangers that humanity causes, and decides that the only way to right the world is to release the beast, eliminating humanity and Godzilla both. That Ghidorah would bring about a new ice age in the midst of a warming climate would give the movie substance.
Well, I had a blast writing this this morning. News is slow right now, so if you have any thoughts or opinions, please comment! Even if you hate it, I just did this for fun!
