Neosapiens visually resemble seven to nine feet tall Terrans with pale blue skin. They have four fingers, including two opposing thumbs, on each hand, and four toes on each foot. Completely hairless, they also have a brightly colored tattoo, a so-called brood mark, on their foreheads, which denotes what brood they were created in. The brood mark is unique for every Neosapien and helps to distinguish them from each other, since their visual appearance doesn't vary as much as humans generally do. Although there are Neosapiens of both genders, they are reproduced only by batched cloning in a brood chamber. They are incapable of sexual reproduction, and are in fact bred to be sterile by the Terrans in an unsuccessful attempt to control them.
Neosapiens are physically far superior to Terrans. They can breathe in far thinner atmospheres, with a much higher carbon dioxide and volcanic gases content (which again makes sense for a race designed to work on Mars). They have greater strength, speed, stamina, hearing, and vision, though the latter also makes them more vulnerable to flash grenades. In addition, they require very little food, have no need to sleep, and have a much greater life expectancy than Terrans. Indeed, Neosapiens have been genetically optimized in virtually every bodily attribute.
Neosapiens' enhanced mental abilities manifest themselves in a greater predisposition to logical conclusions and an eidetic memory. On the other hand, they are burdened by a lack of creativity and imagination, which makes them vulnerable to irrational or illogical military tactics and much less flexible than Terrans once they make a decision. The Neosapiens are immune to Mind Scanners, but dogs are able to recognize their scent from afar and generally behave aggressively towards them.
