Somewhat new character I made for a sci-fi RPG, they are a mechanic robot called COM.B 0004p1, aka.: B.

They like to make all machines they fix extra efficient, and that includes themselves. They are always trying to improve their own body so even tho they started a standard series model they have changed a lot over time.

Their head is also honeycomb-shaped and stores a swarm of small bee-like robots that help them analyze and fix machines sometimes without even having to pull them apart
