This MOC is a Rahi called a Rock Lion, and also a small dude called Zonax. First, the Rock Lion.
The Rock Lion is a very territorial Rahi, which thrives in the caves and Sculpture Fields of Po-Metru, and in the Black Spike Mountains of Spherus Magna. They are very fierce, and don't tolerate intruders in their home. Some beings, with great effort, have managed to tame them.
