Synths are an anthropomorphic, typically reptilian-like, open robot species created by Twitter user Vader-San.
Within the universe created by Vader-San, synths were created by a civilization that experienced a cataclysmic catastrophe that resulted in the rebuilding of their society. This event resulted in death of the majority of the population and most food sources, causing a food shortage among the survivors. However, with the majority of the population gone, attempts to rebuild were futile with an unsteady food supply; energy supply, however, was not an issue. With this in mind, the civilization solved this problem by creating a completely synthetic and sentient species that only demanded electricity to function. These synths were intelligent enough to carry out tasks without needing to be pre-programmed, which aided in the rebuilding of the collapsed society. Soon enough, these synths were met with open arms to its creators and were able to integrate into the newfound society.
In the post-cataclysm world, synths still possess a reputation of being helpful and actively find ways to make themselves useful. As opposed to organics, synths are mostly found working in areas that are otherwise dangerous to said organic life, but can also be found working in the normal sectors of society, such as that of food production and healthcare. Synths are seen as fully independent and free thinking beings, rather than objects like most robots are depicted as. Despite lacking the need for food, synths are fully capable of digestion and even have synth-exclusive food, allowing them to further integrate into social gatherings with other organics. Bearing in mind their independence, synths are fully capable of love, attraction and diverse sexualities just like organics, some even being in relationships with them.
While this lore was intended by the creator, Synths are a fully open-species and can be created, used, modified and inserted into any universe a person would like.
Synths are manufactured like any robot species. Their synthetic brain or processor does not need to be pre-programmed, instead having a complex set of neural networks that learn from experience and develop their own minds in a similar vein to evolution, much like organic life. Synths can have flaws and are not necessarily smarter than organics either. They may be able to think faster, but they are still limited by the size of their synthetic brains. Synth faces are made up of 3D screens to display their eyes and different eye designs can be downloaded like DLC. Digested materials can be used by a synths body to repair and extend their bodies. This digestion is aided by the fact they have a working mouth with lubrication that serves the same function as saliva. Synths are a fully modular species and as such, can change parts whenever they feel like. Synth skin is typically soft and waterproof, though they are able to be changed out like body parts. Synth frames are supported by a graphene frame, similar to metal endoskeletons inside animatronics.
All synths possess a personal swarm of nanites, functioning to repair damaged components and even extend their own body size. These nanites have the ability to utilize digested materials to create new tissue and unique skeletal structures, aiding in the process of body growth. Synths are installed with software blueprints that dictate the size and shape of their bodies and can be changed at any time, though this process can take several months to complete. Synths lack any type of gender, but can present as any gender that makes them feel comfortable. Much like organics, synths are not immortal and will die if their synthetic brain runs out of energy, though their lifespan is still longer than most organics.
Due to being an open-species, none of these are inherent rules but more so guidelines set by the creator to make the species distinguishable. These can be modified by anyone and in any way they see fit.
While people who create and use Synths are not necessarily robot-identified and may just enjoy the aesthetic of said species, a fair amount of robot-identified people may identify with the species. Common labels include, but are not limited to Machinekin and Robotgender.
