Worker Drones

Baby
Worker Drones (after humans had been wiped from the planet) start off as “Untrained Neural Networks”. They are in the shape of an egg, and they have spherical large visors with bright-colored eyes. As a baby, they appear much smaller than their older counterparts, being roughly the size of an adult Workers head.

As soon as they are built, they are wrapped in a white blanket that covers up the majority of their bodies outside of the visors, with a triangular black and yellow sticker that reads "UNTRAINED NEURAL NETWORK" in black text, with two gears at the top of the sticker.

They have so far only been seen with two different eye colors; neon blue and purple.

Teen and Adult
Worker Drones appear as humanoid robots that closely resemble humans’ shapes. The features each base Worker Drone shares include large heads, semi spherical large visors with usually brightly-colored eyes, a muted white muzzle with a mouth, alongside having fangs and some form of saliva inside of their mouths. They also have small triangles on the outer portions of their hands, with the color of them depending on the Worker Drone in question. On the distal parts of their fingers and thumbs, they have grip pads just as humans do. Alongside the similar features, it should be noted that both masculine and feminine Worker Drones share the exact same base.

Worker Drones also sport some form of attire, whether it’s footwear, jackets, or hard hats. Before the humans were wiped, all Worker Drones had bright neon blue eyes and each of them had steel hard hats, wore brown hoodies, alongside coming with their own pickaxes. However, after all of human-life was wiped from Copper 9, they started to have hair and adorned other accessories (taken from the many skeletons) to further show off their personalities, such as headbands, school jackets, and beanies.

Character-wise, Worker Drones act no different from their own organic creators. They’re intelligent and have their own unique personalities. Some can be more approachable while others can be more angsty and brooding. Worker Drones also appear to have some form of knowledge of human culture, as they are aware of things such as piracy, animated content, human hormones, therapy, weapons, and can have feelings of existential dread and deities.

Worker Drones do not exactly possess any special abilities that are integrated into their systems, as they were purely made to be autonomous and not be used in specific scenarios such as combat. Though, some are able to build things out of the objects around them, such as doors and weapons, while others are able to hit and slap each other and themselves, except it doesn’t really deal a great amount of damage. It appears that Worker Drones are able to learn from what they see though, as Uzi, one of the many Worker Drones, has been able to do numerous feats just from pirating anime.

Visor messages
Drones have two bright eyes on their visor that emotes. Under some circumstances, their eyes can be overridden by an error, status warning, or system message:

Absolute Solver symbol replacing one eye or covering entire visor: Caused by the Absolute Solver awakening within the drone or being utilized. The Solver's glyph covering the entire drone's visor is caused when they fully initiate their Solver Form.
System messages briefly covering visor: Caused by minor errors experienced by the drone. An example is Uzi's 'EDGE LEVELS CRITICALLY LOW' error.
Rampant error messages covering visor: Caused by injecting wdOS_606, a core termination program, into the drone.
Warning sign: This is caused by severe damage to the drone's visor like being pierced by a sharp object. It is also found on numerous deceased drones. Uzi also suffers this after being hit by J's EMP.
HIGH TEMP: Accompanied by a warning sign. Self-explanatory, usually appears on Absolute Solver hosts.
FATAL ERROR: This occurs when a drone dies, usually by external causes like severe hardware damage.
X shape replacing both eyes: Used to signify that a drone has died.
Elongated 'X' on visor: Either caused when a faulty OS string is present or when an Absolute Solver host becomes violent and/or starts to transform into their Solver Form.
Flashing ERROR 606 message: Accompanied by an elongated 'X'. This is caused by the removal of one or more core OS strings. Drones with this error are non-sentient, unresponsive, and immobile.
Buffering symbol: Caused by being boot-looped by Sentinels. Like ERROR 606, drones with this error are non-sentient, unresponsive, and immobile.
Text: Can be generated at will to communicate without speaking. It is also used to display when a drone is in SLEEP MODE, as well as emoticons.
Games: Games like tetris can be played in one's screen.
Swirl shape replacing both eyes: This occurs when a drone feels dizzy.
Images: Drones can also display images on their visor.

Zombie Drones
In the case of any Worker Drone that has been rebooted, either by a human or on its own, runs the risk of becoming what is referred to by the company as a Zombie Drone as shown in a JCJenson VHS training tape discovered by N in Cabin Fever and shown in Home.

The video warns against the act of improperly disposing of a Worker Drone marked for disassembly due to the possibility that a drone may reboot without changes (70.3%), carry 'terminal lockout' (29%), or revive with 'potentially hazardous mutations' (0.7%), which can lead to human fatalities or injury. High federal fines may be incurred on the handler's behalf.

N, V and J were Worker Drones that rebooted normally (as they had armbands indicating that they were marked for disassembly and were found by Tessa in a landfill), whereas Cyn was a Worker Drone that rebooted by herself with dangerous mutations, seemingly revived by the Absolute Solver, resulting in her becoming a full-fledged Zombie Drone.

Untrained Neural Networks
An Untrained Neural Network is a premature Worker Drone that is put in infantile pods before being uploaded to a properly functional drone body. After the core collapse on Copper 9, this is noted to be the first stages of Worker manufacturing as, before, they were assumed to be made in factories by humans. For a new neural network to be born, a male and female Worker Drone must both upload 50% of their source codes into an empty shell for their codes to fuse, creating the new personality. However, if either of the parent's code is infected with mutations, those mutations will pass onto their child.
