Cynessa is a grotesque, walking fusion of biology and machinery that serves as the primary cosmic horror of the series. Initially disguised as the human technician Tessa Elliott in a bulky white spacesuit, her true form is a terrifying "skinwalker" hybrid. After brutally killing Tessa at the manor, the eldritch drone Cyn hollowed out the human corpse and stretched the skin over her mechanical chassis. Beneath her helmet, limp dark hair hangs down, and her face is deeply uncanny, flashing neon-yellow digital eyes through ragged slits cut into the stolen flesh. Wholly possessed by the Absolute Solver, her personality combines childlike innocence with absolute cosmic malice. She moves with a stilted tilt and monotonously narrates her own physical actions and emotional cues out loud (saying words like "giggle" or "sip"). Behind this awkward facade lies a deeply spiteful entity that takes joy in psychological torture and seeks to consume entire planets.

Uzi Doorman is an angsty, rebellious teenage Worker Drone whose visual design draws heavily from mid-2000s punk-goth counterculture. Standing distinctly shorter than average, she features glowing purple digital optics and messy, dark-purple hair with choppy bangs. She is defined by her dark-gray beanie and an oversized black hoodie featuring a green radioactive symbol, paired with a checkered skirt, striped thigh-high socks, and bulky combat boots. Her personality is a volatile mix of adolescent rage, cynical wit, and trauma. Severely neglected by her father and ostracized by her classmates, she hides her deep loneliness behind an aggressive, "destroy all humans" persona, wielding a self-made railgun to prove her independence. Despite her defensive prickliness, Uzi is fiercely loyal and protective of her friends. Her internal struggles worsen as she fights the corrupting infection of the Absolute Solver virus, which grants her telekinetic powers but forces her to crave drone oil to survive.

Serial Designation N is a towering Disassembly Drone whose horrifying mechanical anatomy stands in direct contrast to his gentle, wholesome personality. His physical build is sleek and white, featuring neon-yellow digital eyes, a row of indicator lights on his headband, and neatly trimmed silvery-white hair. He wears a dark winter pilot's jacket with a fur-trimmed collar and a matching military officer's cap. Built for mass extermination, his body features sharp steel wings, hands that seamlessly transform into guns or blades, and a flexible tail tipped with corrosive nanite acid. Despite this terrifying build, N is incredibly polite, gentle, and optimistic to a fault. Driven by a desire for validation, he historically endured severe emotional abuse from J. He loves drawing and golden retrievers, always choosing empathy and manners over violence. When Uzi treats him with respect, he becomes a fierce guardian, prioritizing his friends over his killing directive

Serial Designation V from Murder Drones is a deadly Disassembly Drone with a sleek, exaggerated hourglass robotic build, wide hips, and sharp, needle-like peg legs. Her lower limbs feature black-and-yellow hazard stripes, while her black-painted thighs create a distinctive thigh-high sock appearance. She wears a dark gray, short-sleeved crop jacket styled with a prominent golden fur collar and cuffs. Her metallic silver-white hair is cut into a messy, windswept bob with layered bangs framing her digital visor. Atop her head sits a black headband holding five glowing yellow sensor lights. V hides a deeply traumatized past beneath a sadistic, unhinged, and chaotic facade, frequently laughing while hunting Worker Drones. However, this bloodthirsty sociopathic exterior covers a fiercely loyal, protective nature, leading her to make ultimate sacrifices for those she secretly cares about.

Serial Designation J is the epitome of corporate subservience, serving as the hyper-professional, unyielding original leader of the squad. She features a white chassis and neon-yellow optics, styling her silvery hair into two rigid high pigtails tied with black ribbons, and wears a corporate jumpsuit resembling a formal blazer and tie. J's entire identity is dictated by an absolute obedience to corporate synergy and company policy, often rewarding efficiency with branded promotional pens. She is arrogant, perfectionistic, and completely lacks empathy, treating N as a disposable failure. Her character arc culminates in a massive, calculated betrayal. Having always understood more about her true corporate master, when the Absolute Solver reveals itself as an apocalyptic monster using Tessa's guise, J consciously chooses to align with it, prioritizing her own survival and corporate status over any loyalty to her fellow drones.
