Ryobix is a loyal warrior and guard to his master, Valior. Being mostly robotic, the only living tissue is overgrown. Thus creating spikes and his hunched, slender shape. He runs the main AI controlling system for the TRS models. Mostly to keep the system updated, and virus/hacker free. Ryobix uses his holographic screens and pre-recordings to speak. Even though he can speak himself. Ryobix himself is a very advanced robotic system, years ahead of our technology today. Skilled in the ways of defense and doesn’t ever flinch.
As others have mentioned that’s quite a bit of greebling on the body and while it helps with the general image, not sure all of it is needed - given its difficult to really focus on any specific segment without being distracted. Though it works overall.
