Remember that teaser trailer from 2013 Comic-Con, where a multi-legged Kaiju lay dead amongst a pile of rubble? Most fans referred to the creature as Vishnu, because of the voice overlay the trailer featured. However, the name of this Monster was not "Vishnu", it was in fact more likely Rokmutul. Rokmutul is a name given to one of the Monsters originally created by concept artist Josh Nizzi for Legendary Pictures' and Warner Bros.' Gozilla 2014. During the early stages of development, artists were taxed with the job of creating original Monsters for Godzilla to fight; one needed to have wings and one had to have multiple limbs.
The concept art below are two unused Monster ideas which were originally considered for the film, before Gareth and producers decided on the MUTOs. It's likely the unnamed Kaiju in the first Godzilla 2014 teaer, was a homage to Josh Nizzi's early work.
The first concept Monster was called Rokmutul, and he looked like this:
As you can see, the artwork dates back to 2011, when Godzilla 2014 was still very early in production. The second Kaiju, the one with wings, was called Pterodactyl and this is what that Monster looked like:
A third piece of concept art was also uploaded to Josh's portfolio website and it depicts Godzilla fighting Rokmutul. The Godzilla concept in this piece shows a very Dinosaur-like appearance, unlike the one chosen for the film.

So, what does everyone think of Rokmutul and Pterodactyl? Do you think they would've made good enemies for Godzilla 2014? Or are you glad the film crew decided to go with the MUTO design?
