The falling object from trailer 2, what is it?

Either 

A) A flashback of Ghidorah falling to Earth

B) Godzilla/Rodan/Mothra falling down to Earth after being brought into the upper atmosphere by Ghidorah 

Godzilla's_Tail79: All plausible possibilities. Could also be Mothra getting fried by King Ghidorah.

Or it could be Orga!

Okay I'm kidding. ;)

Hey now, let's not get too crazy with the aliens! One alien monster is enough for right now!

Save it for when the Monsterverse is assured past GvK :P

Mothra after being fried by Ghidorah… or Rodan… and I'm thinking Rodan.

Come to think of it, I like Godzilla's_Tail79's theory about the shot being actually a flashback about Ghidorah's arrival on Earth in pre-historic times, alluding to the alien origin of Ghdiroah in the Showa series. So that would mean Ghidorah is fundamentally different from other titans in it's alien origin. 

Sounds a bit fanciful, but anything is possible at this point.  

Honestly, the best evidence for the "Ghidorah is an alien" theory comes from BEFORE the trailers' releases, when Michael Dougherty made some interesting Twitter reposts/responses on NASA Tweets, ESPECIALLY that one about alien microorganisms being preserved in crystals.

TheGMan123: Yeah, although the is very cryptic hint. 

Ghdiorah's Antarctic location is another hint. Being frozen in ice is a homage to the Thing. And the Thing was of course an evil alien planning to take over the world. 

Okay, very funny, Gman with a small "m".

I can take the hint :P

Gman with the subtleties ;) hahaha

Dougherty seems to confirm the alien origin of Ghidirah, look at his quote of the Ghidorah poster, taken from the Bible:

“They have as king over them, the angel of the Abyss. A star fallen from heaven to earth, he opened the shaft of the bottomless pit, and from the shaft rose smoke like that of a great furnace, and the sun and the air were darkened...”

A star fallen from heaven to earth, yup, that's pretty clear indication that Ghidorah came from space and fell to Earth. My theory is that he was probably beaten before by Godzilla in prehistoric times and ended up frozen until now.

Considering the Book of Revelation is a giant metaphor burrito wrapped in a metaphor blanket wrapped in a metaphor house, using it as proof of anything is the shakiest of grounds to make any proclamations.

If you do want to take that passage literally, it honestly doesn't turn out that bad for us. It's just a bunch of weird looking locusts that will torture but not kill us.

Not saying he isn't an alien. Just saying it doesn't prove anything.

EmptyH: Where did anyone say they are "proving" this as verified fact? We are all just speculating. This is no "shaky ground" when we are not proving a fact. 

So no offense, but you really seem to have problems with reading comprehension there...

All the facts so far seem to heavily imply that Ghidorah is some kind of extraterrestrial origin, much like the Showa and now Anime incarnations.

Plus, with a space origin, the space race could easily be used as a backdrop for the classic "old B-roll conspiracy footage" intro that has become a staple of the Monsterverse.

I'm thinking it's Mothra. When I looked closer at the image, I could see the faint outline of wings. The body is too small to be Godzilla's or Rodan's, and Mothra is the only one with a small body height, only standing at 15 meters tall. Mothra also has a history of being set on fire, mainly in the millennium series.

      Its probably going to be in a scene of Ghidorahs origins

I think that by limiting possible explanations of the falling object to titans we already know to be in the film, we'll never figure it out. It's really too high to be anything being dropped (unless it's a really stupid scene) and there's Ghidorah storm clouds in the air, so it's probably not Ghidorah's origin. Any idea's besides one of the main 4 titans?
