History and Lore of the Mechazoa
Eons past, the mechazoa were much like any other organic species. They lived on an idyllic world, lush with deep green forests and sapphire blue oceans. As their species grew and evolved, due to a combination of natural disasters and their own negligence, their beautiful home grew less hospitable.

As intelligent and advanced as they were, the mechazoa lacked the ability to correct their ecological disasters plaguing their world, but they possessed the technological sophistication necessary to adapt. They began slowly at first; small augments to cope with adverse temperatures and violent storms. But as the environment turned against them more and more, the modifications became increasingly extensive.

Generations passed, and with each generation the cybernetic technologies became more intrinsic, shaping not only their physical forms, but their culture as well; they developed cable link technology, allowing the to transfer massive amounts of data and even thoughts and feelings via cables and ports on their back. And eventual breakthroughs in nanotechnology ensured that their offspring were born with the same enhancements and improved further from parent to child: a true techno-organic symbiosis.
This hadn’t come without a cost, however. Among the dangers of mechazoa life at the time was that the parent star was prone to frequent solar flares. These flares could, on rare occasion, damage the nanotechnology that controlled the mechazoan mechanical enhancements, or worse still, corrupt the nanotechnology’s programming. While this pitiable event rare impacted an adult mechzoa in any noticeable way, corrupted nanotech programming typically led to corrupted or damaged offspring.

A compassionate people with a typically nonviolent culture, the mechazoa elected not to destroy these corrupted individuals; instead assigning them tasks that best suited their abilities. While a stigma did grow to exist about cable linking with anyone so corrupted, as it was that often corrupted programming could spread from one individual to another so, a child born of corrupted programming could expect to grow and perhaps even thrive in mechazoa society, albeit with certain limitations.
The exception to that tolerance ended at those ill-fated, corrupted souls born with functional datalink capability; the mechazoa term for ability to wirelessly transfer data from one being to another. Due to the inherent risks of such a person being able to infect countless many, corrupted mechazoa with the ability to datalink were routinely euthanized in order to prevent the harm they could do.

Unfortunately for the mechazoa, after many centuries their ability to outpace the destruction of their homeworld ran out. Knowing their time was running thin, they crafted several dozen colony ships and packed them with as many souls as possible before launching each while intense terrestrial and solar storms raged around them. The rationalized that by splitting their resources that way, they exponentially increased the chance that their species would ultimately survive.

The intent was that each ship would travel to a unique, distant star where they believed they would find habitable worlds flush with natural resources, much as their homeworld had once been. Once there, they would establish a colony and use the remains of their ship to create a sort of hyperspace gateway. That gateway would seek out any other gateways with an identical signature and link to them, allowing those refugee colonies that made it and thrived to reunite and share their worlds and culture once more.

While they are not shown here, they do have reproductive bits, the chest panel and crotch panel retract to show them.
T face plates when locked in position are expressive but they go to a neutral expression before retracting.

They do eat, but its a bit different. they have programs that simulate senses for them that they 'prepare' and distribute like food.
Example: a Mechazoa chef would write a program out of ingredients made of programs and use cable link to give them to others.
Once they're opened, those programs would be deleted. But they would give the sense and satisfaction of flavour for the Mechazoa.
They're powered internally and that their nanites provide their organic portions with fuel. They dp recharge — they go into low power mode for 2-6 hours a day, where their nanites do repairs and build up a surplus of power. This doesn't require them to plug in to anything, but if they do plug into an appropriate charging station, this low power mode time is cut in half.
