I didn't want this to be show to the public so people don't get spoiled. But i have pictures from kong skull island's end credit scene.
DON'T GO ANY LOWER IF YOU DON'T WANT TO BE SPOILED
So the scene goes with One of the characters saying that the world doesn't belong to humans but it belongs to the monsters then there is a monarch image flip thing like in G14 showing the monsters. They are cave paintings I think of them and they are in VERY poor quality from a person taking a picture of them at the theatre.
Godzilla
King Ghidorah
Mothra
and last rodan
The scene then ends with a Godzilla 2014 roar

Even though these aren't very high quality, I'm digging it!

I like that they're shown in cave paintings. This could mean that the 4 monsters have fought in the past in the continuity of the Legendary universe.

Woah, Ghidorah looks huge! I love the new dorsal fins design of Godzilla here!

I'm relieved to see Mothra being presented as divine in some capacity. And I can't help but notice the two figures underneath her in the picture...
Visit Wikizilla.org, the encyclopedia of Godzilla, Gamera, King Kong, Toho monsters and more that anyone can contribute to.

^OMG you're right! I didn't notice before. There are two human-like figures under Mothra.

There's also a fourth image which seems to prophesize the battle between Godzilla and King Ghidorah:

Man, King of the Monsters nailed it with spotting what looks like two little people beneath Mothra... Did not see that the first time.

Wow you're right! Leave it to Legendary to keep close to the source material. God I'm excited for this...

Unfortunately it seems my observation was a little premature. In the film itself I can only see one figure there, it appears the blurriness of these screenshots simply created a double image.

It was a fairly convenient flaw with the image though.

I love how Rodan here sort of resembles the original 1956 Rodan with a similar head design like that of Gyaos. Mothra looks a little decent. Ghidorah looks like a freaking epic dragon.
There's no stopping my Big Bang now!

The Rodan silhouette reminds me of the American poster's design of the monster.
