The Mysterious Creature in the Teaser.. What is it?

This creature was a sample of the Mutos, its what they could have ended up as.

But it was just an experiment, the creature in that picture is the early Mutos, its not another monster ad t wont appear again.

It was a design test for the Mutos but Legendary changed it to a different design for the final product. I dont know, i kind of like that design better ten the Final Muto one.

Its early concept art done because the Muto concept still whasn't finished
