(UPDATED) More Godzilla 2 movie King Ghidorah concept art by Ken Barthelmey

Gotta say, I like this design. It might not make a great Ghidorah, but it could be one hell of a cool serpent titan. 

I agree with YeOldFossil. It would be a good design for some other monster. Just not Ghidorah.

Why? Just Why?

I'm fine with them experimenting. If you look back at the 2014 art book, some of the ideas they were tossing around for Godzilla would've been blasphemy, but you gotta allow the artists to go in those directions to find that one element that may complete the design. 

Like there was one design of Godzilla that looked like a fish and it just wasn't Godzilla, but that fish design led to the gills the Monsterverse Godzilla has.

Sure this design of Ghidorah is just plain wrong, but the horns look like what we got in the final movie and while most of this design could've been scrapped, that one detail might've gone into making the design we see in the final film.

The more I look at this, the more perfect I see it being for a TriStar Ghidorah. This looks like a 3D version of something from the TV series, and would totally fit with the alien origins. It's barely Ghidorah obviously, but so was Zilla, and I bet I would have enjoyed seeing some more heavily redesigned TOHO kaiju in that series.

YES, a full view! My prayers have been answered! I wish he had kept the fur fringe on the necks, but otherwise this is awesome. Time to doodle this guy battling the G-man.

I think we can confirm that the leak was real after all.

Echoing what everyone else said, this is a great design, albeit not for Ghidorah. It's easy to see why they would go this route for the concept art. They definitely had the idea from the beginning that Ghidorah was going to be an extraterrestrial alien, and this look definitely embodies that.
