AR-G0 has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this IG-100 MagnaGuard to more easily blend into the shadows and darkness unseen.

AR-G0 has recieved redundant programming and a mechanical overhaul that reinforces known weaknesses from the original design that allow this IG-100 MagnaGuard to continue operating and survive much longer against a wide range of attacks. This programming overhaul slightly slows processing times while the mechanical fitments can slightly reduce agility.

AR-G0 has had its programs re-written and mechanical systems hard-wired for combat operations. This augmentation gives this IG-100 MagnaGuard a significant increase in combat efficiency in eliminating targets on behalf of Silas Manx, but at the expense of it being usable for much else except for combat.

AR-G0 has developed a personality around the concept of a caretaker. It has assumed the needs of Silas Manx to be its prime directive, even such tasks that have not been requested of it. This results in AR-G0 often flitting about in an attempt to meet any possible task before it is necessary, including menial tasks.
