He was just casually flying above a scarred vegetated mountain range that had large trees and fog scattered all over... flying over and slightly through the mist with his wings stretched mildly.

(He was in search of a female MUTO that was willing enough to accept him as a mate)

He then would suddenly smash headfirst into a mountain - with a loud crash as he stumbled to the ground with a loud pained roar... as he fell into the mist below - onto the ground with the loud snapping of trees.
