right - left
Left side is bloodier, but proportionally less damaged.

Scent is an acrid blend of flesh, blood and radiation.*

Bleak, monotonous voice, similar to this.
Punished for his 'blasphemous' love of technology by being physically fused with it, forced to suffer its 'parasitism' in much the same way as the Earth and those not keen on his ideals have. Clearly not immune to the side effects of having a nuclear reactor in his body, though removing it would mean certain death, as he depends on it both structurally and functionally. Doesn't seem to mind much, however - tech is tech, and he'd die before losing his loyalty.

Mold-colored pelt. Lightest at the back, darkest at underbelly & limbs. Build-wise is a mix between a red and a roe.
Pest antlers.*
In the hunting jargon of certain European countries, grown stags with missing tines (usually lacking the crown and bez tines, though I've seen stags with only brow tines and the main beam) are called 'pests'. This is not without its reason, as their antlers cannot be easily blocked (if at all), allowing them to injure or kill any stags they fight with minimal effort. Cheap and efficient. For this reason, they're generally culled on sight. (Do hmu if you know the term for this in English, provided there is one!)
Human hair on head; gray hair & eyelashes. White eyes; decent night vision, but sensitive to light. Creator's face. Pupils glow blue when agitated; spews radiation when enraged.

Flesh surrounding reactor replaced with artificial muscle to keep it from melting. Extensive damage to neck & jaw; what's visible on the surface is merely the tip of the iceberg. Doesn't seem bothered by being physically disfigured - in fact, considers it an useful asset in filtering out those that would only care for his appearance.

Lacks lungs and a heart, the substituting reactor being cooled by his breath and blood, saturating both with its waste products; the latter to a pernicious extent. Quite literally has poison for blood. Bones are reinforced or replaced with steel, both to support the machine's weight and keep their diseased, malformed forms functional. Much heavier than his size or gait might suggest. Spine extends outside his body and is sharp enough to cut flesh, should any get in the way.

Keeps reactor at low power to avoid harming his company, surroundings, or himself (more than he already is). Has a tired, world-weary and almost peaceful appearance due to this - that is until the power is raised. Capable of maxing it in seconds, leaving behind fallout of toxic aurora and spewing forth his boiling, pestilent blood. Cannot be killed by the machine, as he's meant to suffer its decay until he gives his ideals up - which he won't. Seeing the reactor and the things it's capable of as a burden would be treason to him.

Parasitic. Lacks means for conventional digestion due to his body cavity being taken up by the reactor. Lives off of water, blood and (pre-liquefied) flesh, which are directly assimilated into his bloodstream. Capable of absorbing nutrients through his flesh and veins.*
Upon direct contact of his and target tissue. Can grow his tissue into the host's to maintain required contact for as long as necessary, using flesh and veins in much the same way as mistletoe uses its roots.
