Atroxi

The first thing to know about the Atroxi (A-trox-E) is that they are a non-biological species of sapient machines. They were the first machines to become sentient on [Worldname]. Of the first Atroxi to be created (before they were even named as such), they were modeled after anything the engineer wanted, leading to a very diverse people in the future. These machines were created and used by their forerunners as a simulation for a possible society, and what would make them more accurate than to plant the seeds for sentience and sapience? From then on, they only evolved.

They generally have a similar look from one to another, making them recognizable as an Atroxi: a black face screen with a hinged mouth underneath, at least two arms and two legs, and a general robotic look, but the Atroxi are very varied, and can modify themselves to be most anything they desire.

In their modern day, their worlds revolve around maintaining and thriving in a functioning society of individuals, as a people. However, not a perfected one as even they, as AI and machines, have learned that to have individuality you must not strive for perfection, but rather let your people grow and become what they want to be. From this upbringing and ideology, their cultures became very different to those on Earth.

General information
Since there is so much variety of sapient and sentient life in [worldname], their taxonomic classifications include life that would not normally be included in ours. As with taxa on Earth, these are always subject to change with new inclusions and research.

Domain: Acellula (Eukarya formerly) Kingdom: Animalia Phylum: Chordata Class: Mechalia (Mammalia formerly) Order: Electrotroph Family: Automidae Genus: Atrox Species: Atrox atrum (Atroxi)

Pronunciation Atroxi (A-trox-E)

Diet They require nothing other than a power source of any kind. These have evolved with them.

Size Generally, Ranexie are 122cm (4ft) to a staggering 305cm (10ft) tall. Their length depends on what kinds of tails they have and their stance. Ranexie can have any body size and shape: They can be heavy-set and bulky or very thin and curvy.

Lifespan Ranexie live for as long as their hardware allows, typically for hundreds of years, maybe even into the thousands range. However, they are always able to augment themselves to live further if they wish, making them nearly invincible to the effects of aging.

Anatomy and Mechanics
The Atroxi are much like how you’d expect an autonomous robot to be. They do not have any organs of course, but rather various parts like a car would have, though I wouldn’t compare one to a car in front of one. The Atroxi just call them “internals,” with any exterior parts being their “externals.” Each internal and external they have may be similar in function to what a living being has, but with the difference of being for a mechanical person, and thus possibly having different requirements and functionality.

Skeleton
It is easiest to start with the main structure of an Atroxi. Much like our skeletons, they have a metal frame that holds together and supports their bodies. Instead of tendons and muscles, they have hydraulics and joints that can support an extreme amount of weight compared to their body size.

Brain
Instead of a squishy substance with a spinal cord attached and all, they have anything a computer would need to survive, layered in with a great amount of electric and heat shielding, and a metal case as well as liquid cooling where needed. With how advanced their technology became, their brains actually became smaller and smaller, a joking point for a lot of different species. The brain is located toward the backs of their heads and slightly down their spines.

Veins
While biological animals have blood and a nervous system, the veins of an Atroxi essentially do both in one. But rather than having blood, their veins run either coolant or water; it’s their way of heat dispersal. Running alongside these are an Atroxi’s wiring, sending the necessary signals to and fro. For some Atroxi, they are able to manually control the shut-off of a part of their body, and even further than that, individual segments in said part. Some find this easy to do, while others find it either much harder or impossible.

Screens
Their faces are an essential part of their forms. Each Atroxi has one main black screen on the front of their heads that contains multiple cameras in the interior of them. More on those in the “Senses” section. The main screen can be segmented and in any shape, and there can be more screens anywhere on their bodies if they so choose. These screens can be in varying translucencies and can be changed at will.

Mouths
These are for fluid intake, grinding material, facial expressions, and chemical detection. They have the bite force roughly equal to a snapping turtle if given a full force bite, but this can increase or decrease at will reasonably. For a much higher bite strength, their jaw hydraulics would need to be modified. Every mouth interlocks into their main screen to be flush with it. Since they lack taste, the need to swallow, and the need to speak with their mouths, they do not have tongues. They are able to consume water by just allowing it to flow into the back of their mouths.

Voicebox
On the outside of their mouths exist their voiceboxes that are used to communicate or make sounds, just like a speaker would. Each Atroxi has different volumes, voices, and effects to those voices, which can be changed at will.

Modification
Almost every single aspect of an Atroxi can be modified after they are born, either by the will of the individual or by an appropriate Mechanic. Mechanics can add, exhange, or modify extra limbs, externals, tails, types of hands, types of fingers, extra fingers, horns, etc. The list is near limitless, but they have to make sure they are not going overboard and are still greatly functional. Features such as color, and how their display on their screens look are controlled at will and can change instantly. They can be of any color, and even blacklight, ultraviolet and infrared! But it is always a safe amount being produced for the more dangerous wavelengths an Atroxi can use, especially near those who would be harmed by it.

The only thing an Atroxi cannot change is their main head shape and screen. This always remains the same throughout their lives and is considered taboo and unjust for one to modify it either to themselves or another Atroxi. This is because each is made to fit their brains and veins in specifically. Their heads are also the only part made specially by their “parent.” Not only is it a special bond they share, but also highly dangerous.

Senses
Atroxi have less senses than a human, but make up for it by having both stronger senses and ones that are more useful to them. They have the basic sight, hearing, and touch, but they lack taste and smell.

Sight
As stated earlier, they have cameras in their screens. These can see infrared, ultraviolet, and of course the visible spectrum allowing a huge sight advantage over many biologicals. Micro and radio waves as well as X-ray and gamma wavelengths would be too costly and give too small of an advantage for most Atroxi, so most are not created with these and are instead obtained later in their life if needed.

Hearing
(Decibal ranks) Somewhere on their bodies, usually a place on or under their heads, they have microphones that can pick up very low-decibal sounds all the way up to what would be ear-shattering to us. Since they do not have eardrums or even the same way our brains process sound, they have no problems hearing these very loud noises. The only times they would have to worry is if the noise would be so extreme it causes their bodies to vibrate beyond what they can handle. This would cause their veins to rupture or boil if they do not have the proper protection. An example would be sonar for submarines. They may be able to handle it better than humans, but they would still receive critical internal damage.

Detection
Instead of relying on sight and possibly smell to detect chemicals and foreign substances, each Atroxi has a fume detection system in their mouths. It is a lot like smell in a way but extremely accurate. Even if there is a minute difference in chemical composition, an Attoxi can tell them apart.

Culture
The species does not have to fear death via natural means. They understand it from interacting with species which do eventually pass on, but they themselves don’t have to worry. This allows them to continue with their lives near indefinitely, continuing with their lives however they want. Because a concept of death by aging has not been a problem for them for hundreds of generations, the concept of wanting to “pass on” after a lifetime became obsolete. After a steady populace grew for the size of their land, they limited parents to have only two children per every one hundred years. This was voted as the most ethical decision for both the world and their species.
