My masterpiece! Stefan is now under my control!The Surgeon

Stefan is a friendly glowing one in the CEO offices of the Red Racer factory in 2277.


Stefan is the Surgeon's test subject or more politely referred to as an "assistant." It took a considerable amount of trepanning (and radiation medicine) for Stefan to become docile and loyal. Stefan's job is to maul or cloak in radiation any intruder that dares threaten his master, as well as test subjects the Surgeon deems too unruly or not reacting properly with their implant chips. These are never referred to as "mistakes" though; the Surgeon doesn't make mistakes.[1]
