Roi Shepard

Staff Commander/Rear Admiral Roi Shimon Shepard (Hebrew: מפקד בכיר/תת-אלוף רועי שמעון שפארד; IPA Name: ʁoʔi ʃimʔon ʃɛpərd) is the post-human protagonist of Revoking.

Biology
Shepard's gentic material is made from XNA rather than DNA. His cells are equipped with 2 nuclei.

Biological Ehancements

 * The Secondary Heart resembles a smaller version of the human heart and is loctaed in the chest cavity and connected to the rest of Shepard's circulatory and pulmonary systems near the original heart. Its function is to enhance his performance by supplying more oxygen and nutrients to the muscles by increasing blood flow well-beyond that capable for even the most fit normal human being.
 * Shepard's advanced skeleton is slightly larger yet exponentially stronger than a heavily augmented human's with growth having topped out at 196cm (6'5$11⁄64$") in height with an equivalent amount of skeleto-muscular mass.
 * In addition, Shepard's Rib cage is fused into a solid mass of bullet-proof, interlaced bone plates. The resulting structure protects his organs from damage in a way the normal human skeleton never could, though at the price of producing greater difficulties for Medical Personnel when they must perform surgeries on Shepard's body cavity.
 * Shepard's blood's biochemical composition is modified to carry oxygen and nutrients more efficiently, which, in turn, turn hiss blood a brighter shade of red than that of normal humans.
 * Shepard also has enhanced resistance to toxins:
 * Shepard's liver is enhanced to be exponentially stronger than regular human livers.
 * The Foodfilter is a second stomach spliced into the human digestive system above the original stomach that allows Shepard to eat otherwise poisonous or completely indigestible materials. The Foodfilter is capable of biochemically analyzing ingested materials and neutralizing most known biochemical and inorganic toxins, and many others that remain unknown save for their toxic effects. Deadly poisons are either neutralized or isolated from the digestive tract by the Foodfilter. The Foodfilter can also be isolated from the rest of the digestive tract to deal with particularly toxic substances that Shepard may simply vomit back up later. Often these extracted toxins are rerouted and then molecularly stored in the Liver.
 * The Lungs are doubled in number, to absorb oxygen from environments usually too poor in oxygen to allow normal human respiratory functioning, and enhanced with highly efficient toxin dispersal systems.
 * Shepard's upper nasal passages are enhanced - whe he chews, tastes or smells a substance it is biochemically tested for toxicity and nutritional content, essentially determining if the substance is edible or poisonous. The enhancement also allows Shepard to identify extremely subtle odours with the same fidelity as a dog bred for tracking, allowing him to even track his quarry by taste alone.
