Uzi is the rebellious daughter of Khan and Nori Doorman who initially sought to battle against the Disassembly Drones that hunt her fellow Worker Drones, as well as JCJenson and humanity as a whole. Eventually, she forms a friendship with a Disassembly Drone named Serial Designation N (which later develops into a romantic relationship), with the two working together to learn more about the Absolute Solver, an immensely powerful Eldritch intelligence that affects her. Following the events of "Absolute End", Uzi succeeded in destroying Cyn's heart and prevented the Solver from taking back her form by swallowing her singularity core of the Solver. This action caused the melded form of Tessa's corpse and Cyn's drone body to collapse into oil and blood, but it inadvertently made Uzi the Solver's new host, which let her inherit the abilities of her late predecessor. Unlike Cyn, Uzi still retained her personality and was not fully overtaken by the Absolute Solver, the Solver only shown to manifest through her tail.

uzi is 18 Uzi takes on the appearance of a short Worker Drone with neon purple eyes and short, dull purple hair. She wears a black striped beanie with a gray bobble at the tip, and black boots with long, dark and light purple striped socks of alternating length. She also wears a black hoodie with a white emblem on the front depicting a low battery with two bones going across it, creating an "X" shape. The bottom of the hoodie has two white stripes wrapping around it, and the left sleeve has a white Secchi disk symbol on it. The hoodie also has black fur around the bottom and the collar. She also has a black choker around her neck with a skull and the number "002" on it.

After assimilating the Solver within her, Uzi's eyes shift to an orange-purple gradient. Her left wing is now white and yellow, the same color as Cyn's wings. While her tail remains relatively the same, the Absolute Solver is now capable of possessing it (and only it), so whenever it does take control of it, its eye color changes from purple to yellow. Uzi also sprouts three tentacles from her back, which she can get rid of and summon at will. In the music video for "Fight 'Till I'm Good Enough", Uzi wakes up in her pajamas: a short-sleeved, dark purple shirt with a drawing of a square robot head in white with pink accents. Under this shirt, she wears a thick, long sleeve shirt with purple and white stripes. On her head, she wears a black cartoonish sleeping hat. Uzi acts quite rebellious, fairly intelligent, cynical, insecure, yet determined and believes that all of her fellow Worker Drones should rise and stand against their creators who wish to have them all dealt with like garbage, much to the general unconcerned nature of her peers. She has been described by Liam Vickers as a "little devious twerp." Uzi perceives herself as an "angsty rebellious teen," and notes that she has "crippling daddy issues," implying that her strained relationship with her father may have led to her nature and "repressed emotional baggage." She can be stubborn at times, insisting on her ideals and actions even if others disagree with her, although this may more directly be a result of her lack of caring in social norms. Despite her emotional issues, Uzi's intelligence seems above that of her fellow workers, seeing as she built a railgun that can produce enough power to destroy a Disassembly Drone from scratch. However, following her self-exile from her colony, she began to develop paranoia as a bizarre symbol begins appearing in her eye causing glass to crack whenever she attempts to look at herself, leaving her unsettled. Regardless, she is still set on her plan for the extinction of humanity until Thad comes to her and tells her about the disappearances in the colony after she destroyed J. Despite her dislike of her people, she chooses to return upon the realization that J may have survived the blast and comes upon a mysterious clue with something called the "Absolute Solver," further provoking her paranoia. After barely escaping from Eldritch J, Uzi is outright traumatized, reacting fearfully to physical contact from N and becoming more obsessive in her research into the Absolute Solver, though as she encounters more and more dire situations, she manages to overcome them, and become more selfless as a result, and more willing to step into the line of fire. Following the events of "Heartbeat", "The Promening", and "Home", Uzi appears to have reconciled with her father, no longer ignoring towards him and willing to hear him out when he talks about Nori, even if only somewhat. She even develops an intimate relationship with Serial Designation N over the course of the series, displaying jealousy over other campers hanging out with him at Camp 98.7, and this proves to be her breaking point, releasing her Solver Form in a fit of insanity. This was eventually resolved with a heart-to-heart with N, where she revealed that she fears being forgotten and being left alone. After the final fight with Cyn in "Absolute End", she has ultimately acclimated to the colony, and claims that she "doesn't totally hate it," even garnering some respect from her classmates (in addition to direct support from her now-established boyfriend, N, and her friend, Thad). However, she is still prone to impulsive action, such as when she releases her Solver form to show her class, much to their shock. As of "Fight Til' I'm Good Enough", she seems to have become a lot more courageous and confident thanks to N and V, pulling pranks on the colony with them. Despite this, she's shown to be highly defensive of it, as once her tail begins the zombie prank, she, as well and N, V, and Sparky start taking down the zombified drones. She also makes an attempt to save Thad once he gets infected and buried under rubble. She also seems to be aware of N's fear of failing her, as when he starts panicking while fighting the giant zombie Sparky, the note Khan had flies in front of him and Uzi eats, shooting N a thumbs up afterwards.
