Here is a quick concept for the inhabitants of the planet Kepler. They are going to be a primitive race of aliens who team up with the marooned Tryons. I based a lot of its anatomy on a gorilla, and was thinking they could also use their powerful for climbing trees and rocks etc.

I like the concept of them being tribal almost warrior-like, I added some basic tattoo designs and based the colour on the aboriginal paintings.

I sketched this thinking it was cold blooded like most amphibians and uses the power of the sun for energy. Its skin has like a hardened shell covering the chest and back for absorbing sunlight

I'm also thinking this creature to be a herbivore and feeds off mainly the special liquid produced by the trees on Kepler. Its quite an easy food source which means they don't waste too much energy.

I'm still unsure where they could live, I was thinking either in the jungles of Kepler or in these caves away from the sun in order to make it easier for their bodies to shut down.

Anyway The Anoki have an important role in the story, they are the ones who save the Menewa and the Pronaxians on Kepler and lead them to their hidden community where they hide the marooned prisoners from the guardians of Kepler.

Still got some exploring to do but I like where this idea is going.  hope you likes
