Cyber

Cybers are mostly artificial creations that possess free will and are capable of thought and creative thinking - putting them right next to humans on the “evolution ladder”. At first designed for military use, they soon reached an alarming level of sentience that, after long discussions centered around fears of “Cyber revolution”, granted them citizen rights in many countries of Teurora, in turn giving them equal rights to humans.

Gen One "Warbots"
First Generation Cybers are the first type to be created. Their artificial intelligence was the most advanced one in the world when they first appeared, which proved to have many military applications, mostly thanks to their threat recognition on par with humans. They possess no emotions of their own and also need to rely on human guidance in the field to be effective. They do not require any kind of recharge as long as they are not damaged, allowing them to perform their duties without stop. They are durable and slowly regenerate “injuries” over time, but only if enough Cyberian remains in the metal plating - sufficient damage will lead to destruction without much hope of repair.

It’s simple to distinguish them from other types - most Gen 1s are mostly wheeled or tracked vehicles, with only some rare exceptions resembling humanoid skeletons - it was much cheaper to produce “drones” over bipedal machines.

Gen Two "Sentient Robots"
Gen 2 Cybers are way more advanced than their predecessor. Thanks to Cyberian-199, they now have human emotions and are completely free willed, allowing them to take on the same jobs as humans do, no longer limited to military uses only. Just like Gen 1, they are still made of metals and Cyberian, making them durable and slowly regenerate their wounds over time. However, just like in the previous case, sufficient damage will destroy a Gen 2 without a chance of repair - they are no different than people. They have no need to sleep or eat and, thanks to Cyberian-173 storage recharging their power, can operate at all times if they are not wounded - in which case some of their energy will go towards regeneration and will weaken the Cyber, sometimes shutting it off until the repair process is complete. Destroying the CBR-173 storage (located near where a human heart would be) will lead to quick death, as there will be nothing left to power Gen 2 up.

As stated in the official talks, Second Generation Cybers cannot resemble a human. They still are humanoid, but must possess features to differentiate them, such as different head shape and lack of human face... However, some ignore those rules.

Gen Three "Augmented People"
Upon the discovery made by Doctor Edgar Sterning, people can choose to  become a Generation 3 Cyber. Not made artificially, but rather augmented with more than trace amounts of Cyberian and other technology, Gen 3 gain better strength and agility, heal slightly faster (albeit not as fast as artificial Cybers or Cybermancers) and age much slower. However, they also become highly sensitive to Cyberian that enters their body which is different from the one they were augmented with. The scale of augmentation differs per person - they may either opt to simply heal their damaged organs or completely replace their limbs with crystal-powered ones, if they so desire.

Sometimes people become Gen 3 as a result of surgeries if no other option than augmentation would be able to save them. The process of augmentation, voluntary or not is irreversible - once one gives away their humanity for the sake of progress, they cannot come back to being a pure human.
