Shots of oil wells...and I think I saw the eye of the kaiju emerging from the mountain.

Though we still don't know whos side Rodan will be on, we at least do know that they will have a fight at some point.
Also, I think it is pretty safe to say that the mountain kaiju is an original kaiju and not Baragon/Anguirus. We get a pretty clear shot of its face and there is no horn to be seen. Also, the mountain kaiju is located at Munich Germany which is one of the locations that can be found on the Monarch Sciences site.
Long live the king...

The mountain Titan looks like it has a face made of stone.

Titanosaurus confirmed!

Hahaha I would love it if Titanosaurus was in this! An underrated and under-used Monster imo.

The desert one looks insect-like (or is at least an arthropod-like creature), and the mountain one looks like it would be some sort of reptilian. Can't wait to see what these two look like.
Also, using the high-pitched Showa Era or Heisei Era Godzilla roar. (Let me know which one it is. Thanks.) That was just dumb. As if we didn't know the actual sound of Monsterverse Godzilla's roar already.
