Homo kukeris (or simply: Kukeris) is a humanoid transapient race developed by Kuin on 2025. The use of genus homo is misleading, because genetically and anatomically, they are vastly different from a normal human. Meanwhile, morphologically they're superficially humanoid. At around 2050s, kukerises are reassigned as a new genus known as Kukeris, so default Kukeris has a binomial name of Kukeris kukeris.
Adult kukerises are about two meters tall and massed more than or equal to 100 kg. Their body plan is humanoid, with skin tone of dark grey, to make them contrast from normal human skin. They appears to be up to four times as strong as a normal human of similar size and build, but this is because they can gang up more muscle fibers at once than a human could, while also capable of fine movements better than a normal human could. Numerically, their maximum physical power output is just about 30% higher than a normal human. Their physical power output is about 600 W, compared to a normal human that can comfortably sustain about 300 W to 400 W of power output. It is safe to say that we can produce about ~500 W.
Compared to a normal human with a diet of 2,800 kcal per day, they require three times as much as human food portions. Their actual average daily energy requirements are 7,300 kcal per day, which, with normal human’s digestion efficiency (about 30%), would require about 24,300 kcal worth food contents per day, or close to about nine times as much as human food portions. However, their digestion efficiency is closer to about 80% efficient. Therefore, they are more able to efficiently digest and extract nutrients and more calories from their food.
Their unique traits are not with their body that is basically just improvements of a human’s millions of year’s worth of evolution. Their defining feature is in their brain. A normal human brain volume is about 1.3 liters, while a kukeris brain volume is about 1.8 liter, and massed about 2 kg. About 60% of its volume is kukeris’ computronium gel (about 1070 cc), weighing 1.2 kg. It contains about 220 gr of carbon, and about 10% of it is about 22.2 gr of suspended microscopic diamond-based phononic computronium. At about 10 carbon atoms per bit, its storage capacity is up to about 1.1E23 bits. Their brain consumes up to 135 W of power (nearly ten times a human brain’s metabolic needs), and can provide computational power of up to 1.5E22 bits per second (bps). In comparison, a human brain’s computing power is estimated to be about 1e18 bps.
Their cranial bones and vetebral collumns can also support computations and data storage.Their cranial bones and vetebral collumns are composed of 60% bone at around 2 gr/cc, 20% polymer at 0.8 gr/cc, and 5% diamondoid at 1.68 gr/cc. Therefore about 176 mg/cc of their cranial bones and vetebral collumns are diamondoid computroniums, and the computronium-infused bone structure is named skeletocomputer. Their cranial bones comprised of about 700 cc of skeletocomputer that equals to about 123.2 gr of diamondoid computronium capable of storing up to 6.2E26 bits (at 10 carbon atoms per bit). While their vetebral collumns comprised of about 200 cc of skeletocomputer that equals to about 35.2 gr of diamondoid computronium capable of storing up to 1.8E26 bits (at 10 carbon atoms per bit). Combined, their skeletocomputer structures consume about 10 W, and can supply up to 1E21 bps of computing support.
