Evil! Uzi

Dark pink hair with a light pink gradient, pink eyes, white hat with cat ears, pink leotard under a pink dress with sleeves with white bows, White socks with pink shoes, with a love heart hair clip.

Sweet, kind, loving, loves humans.

When first created by JCJenson to mine resources from exoplanets before Copper 9's explosion, all Worker Drones wore hard hats and orange jackets, with their only eye color being light blue.

Following the core explosion of exoplanet Copper 9, all humans on the planet were wiped out, turning it into a winter-apocalyptic wasteland. Seizing this opportunity, the Worker Drones quickly picked up where the humans had left off, formed their colony, and embraced this newfound freedom by wearing human-like clothing and having different eye colors. Known colors they can have are red, orange, green, blue, cyan, aqua, magenta, pink, purple, and white. When a Worker Drone feels fear, shock or other intense emotion, their eyes become hollow, with a black circle overlaying the normally fully-colored eyes.

A key trait to notice about the Worker Drones' eye colors is the total absence of yellow. This trait was thought to belong solely to the Disassembly Drones until it was revealed that they were once Worker Drones themselves and that their yellow eye color originates from the Zombie Drone, Cyn.

After 'banishing' herself from the colony, Uzi sadistically rants about how she wants to kill all humans on Earth in retribution for sending the Disassembly Drones to kill them all. While doing so, her right eye turns yellow while her left eye turns into a yellow hazard symbol hinting at the presence of the Absolute Solver.

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, as seen with Cyn.

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.

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.

Absolute Possession The Absolute Solver's most noteworthy ability is the complete possession of a host. The Solver has full control over the body of its hosts and can use its powers to a greater extent. An example would be Cyn, the Solver's first known host.
Matter Manipulation The Absolute Solver is able to manipulate matter at the atomic level. This can be done to create new objects out of old matter (See Regeneration), or convert dead organic matter into living matter. In Cabin Fever, Uzi was shown to transform an arrow shot at her into a deformed mass of still-living flesh, and both Cyn and Uzi have been seen creating organic body parts that they grafted onto their bodies, including wings, tails, tentacles and claws of varying sizes.
Telekinesis Demonstrated with users like Doll and vessels such as Cyn, Nori, and Uzi, the Solver can be used to interact with matter without making physical contact. This includes translating objects in any direction or rotating objects around a point. The Solver can exert a large amount of force this way, enough to crumple a thick metal door almost instantly.
Teleportation While being used, the Absolute Solver's known hosts are shown to be able to teleport, leaving behind yellow afterimages as it does.
Illusion Creation Whenever using its powers, the Absolute Solver can conjure lines of code, which vary in color depending on the host. It is unknown if this is controllable or not.
Shapeshifting While in control of one, the Absolute Solver can alter the appearance of their host. For example, V, during her time at the Elliott Manor, had her right hand replaced with a set of claws; she also sprouted wings. Meanwhile, Uzi grew a tail and similar wings during her rampage in episode 4.
NULL Creation The Solver can create NULLs, which look like miniature black holes capable of expanding and stretching. The black holes could annihilate any matter they touched and travel at high velocity when thrown.

Hand Amputation Hosts of the Absolute Solver need their hands to use its power. In Mass Destruction, while Uzi was under the control of the Solver, Nori and N cut off Uzi's hands to temporarily prevent her from using her abilities.
Decreased Dexterity with Claws During the scene in Home where the Absolute Solver was attempting to perform a lobotomy on N, it appeared unable to pick up a scalpel with one of its tarsal claw-like arms.
UV Light While Nori was under the control of the Solver, UV rays caused her mechanical claws to burn up and become visible. Similarly, back at the gala, Cyn's mechanical claws were revealed when the light from the lightning behind her exposed them. Finally, in Absolute End, Uzi blew a hole through Copper 9, disintegrating Cyn's heart by allowing sunlight to shine through from the other end of the planet to reach her.
Overheating/Vampirism In some scenes where the Absolute Solver is used by a host, it sometimes shows a high-temperature warning. It also has a reliance on oil to maintain a cool enough temperature to consistently use the Absolute Solver's powers. In addition, this makes hosts of the Solver extremely sensitive to sunlight, such as Uzi's hand burning up when it makes contact with the rising sunlight at the end of Cabin Fever.
