The first pic I got off of a Korean Movie Poster website about 2 years or so ago and I could find absolutely NO information nor duplicates of it. Fast forward to tonight and I happened to find image number 2 which appears to be the same Mech. My question is, Who or what is this robotic three-headed dragon? The site I got the second image from I had to translate it from Japanese and it said something like "Space Monster Mekaghidora vs Monster King Godzilla." I've seen every single Godzilla movie(except the Wolfman fan-made film) and Mecha King Ghidorah looks absolutely nothing like this. Can someone please help shed some light on our mystery kaiju?

I think might be from a Japanese Hobby Magazine. I did some translating of my own(found a list of katanaka, wrote down a couple of the more important looking, bigger texted words on a piece of paper, used Wikipedia for copying and pasting), and ended up on a Japanese twitter account here:

Bing translated it...kinda weird for me, and the first picture might be from a 1983 issue? There's some more pics on the twitter if you scroll down.

I have no idea where the more recent action figure came from. Garage kit/custom maybe? That's all I can find out for awhile now. I hope I've been of some help!

Appreciate the reply! There's some cool looking art on there. A few piece I've never seen before like the one of Godzilla fighting "MekaGhidora." I do have one theory though. Maybe there was a magazine-only comic/story surrounding MekaGhidora and he either wasn't meant to be in any movies or was completely redesigned for GvKG (1991). You know, like how the Transformers characters Star Convoy and Battle Gaia appeared only in magazine comics but still had toys based on them. It maybe a stretch, but it's the only conclusion I can come to. Lol.

Still, that dragon looks awesome
