You are

who mutates into a host for the Overcomputer. Her goal is to exterminate all humans as revenge for the drones' neglect, which results in her destroying Earth and several other planets. It is Sin who indirectly causes the core explosion on the planet Copper-9 and sends killer drones there to infiltrate JC Jenson's labs. One of the main antagonists of the series.

a viral artificial intelligence program of unknown origin that grants its host superpowers. It was first found in a drone named Sin, who became its host. The Super-Computer grants its abilities to those drones that are infected with it, but they pay for this by overheating and possible loss of control over themselves. Its abilities include control over space and matter. It can also create black holes and destroy planets. Infected drones may develop wings and a tail like Uzi, and tentacles with spikes on the ends. One of the main antagonists of the series.

character from the Killer Drones series. A Worker Drone who became the first carrier of the Super Computer.

Nothing is known about Sin's life prior to the events of the series, but it can be assumed that Sin was improperly disposed of and sent to a junkyard. Sin awakens in a junkyard, where she comes into contact with the Over Computer and allows her body to be taken as a host. It is implied that after these events, she was picked up by Tessa and brought to the Elliott Estate, but it is not certain whether Sin was still herself at this time or whether the Over Computer completely absorbed her immediately. One thing is certain: by the time of the events of the series, the Computer had completely suppressed Sin's personality.[1]

In the finale (episode "Absolute End"), Sin's body was destroyed by Uzi, but the Calculator moved from Sin into her.

Sin is the shortest Worker Drone in the Elliott estate. She wears a maid outfit, like Jay and V at the time. A large bow can be seen on her Worker Drone helmet, which is painted black.

Cyn's hairstyle is modeled after Tessa's: a small section of hair in the middle of Cyn's head is combed to the right side, and two long braids hang down her shoulders, tied with black elastics. Two more of the same braids are tied at the back.

Having taken over Sin's body, the Calculator used it as its own vessel. It is capable of existing separately from Sin's body, but in this form it is extremely vulnerable. Destroying Sin's core and the black hole that feeds it means death for the Calculator.

Biography
Episode 2 - Heartbeat
In N's memory, young Tessa brings a new maid, the Worker Drone, to the mansion, after which the dream ends.

Episode 4 - The Cabin Syndrome
After N touched JCJenson's "Zombie Drones" training VHS tape, he remembered Sin eating a man and hanging his dismembered remains around the house. She had the Overcomputer symbol in place of her right eye.

Episode 5 - Home
She is first shown in a junkyard on Earth, rebooting under the corpses of other discarded worker drones. Long after, she is seen living in the Elliott estate.

However, over time, its malfunctions (caused by the increasing influence of the Overcomputer) became very noticeable, which apparently irritated Tessa's parents. To calm them down, Tessa and Jay decided to lock Sin in the basement. However, from time to time, Sin supernaturally emerges.

En meets Shin at a bar near the library, where they discuss plans for the evening. Shin forces En to ask Tessa's permission to attend the event.

Arriving there with En, they see James, as well as Jay and Tessa, who are not very happy about Sin's presence. When Louise, Tessa's mother, approached her daughter, she forbade her to bring her "pets from the trash" to the event and said that she would throw out the broken robots from the library, to which Sin responded that they were not broken and that they could not be thrown out anymore, which angered Louise, but En defended her.

She is then shown in Tessa's room, with Tessa tied up in chains. Sin turns into a monster, and after threatening Tessa not to go to the celebration, leaves through a broken window.

Sin interrupts James' speech, after which Tessa bursts in to commit "civilian murder." After her parents tell her that Tessa is holding the gun too tightly, she pushes the Elliotts away, trying to tell Tessa that she came in vain. She is irritated by Tessa's resistance and Sin turns off the lights, capturing all the drones (including Jay) to stage a "bloody celebration," and together with them, they wreak havoc in the Elliott mansion.

Episode 7 - Judgement Day
The supernatural Sin appears as a hologram to hug En and then drag him away to feast on him. However, Nori saves him. In the end, she is in a spacesuit and wants to finish off Uzi, but En blows off her head. However, not for long. After that, Sin gets rid of the spacesuit and appears in her true form.

She wants to drag En and Uzi into the hole, but only Uzi can be pulled in. After the "victory", she begins to destroy the planet with the help of the super-computer.

Episode 8 - Absolute End
She, as the main antagonist, destroys Copper 9, and together with Jay confronts Lizzie, Ted, and Han. Nori meets with Uzi, and tells her that since the patch is destroyed, all that remains is to destroy Sin's core. When Uzi and En return from space, she reveals herself and almost kills Uzi by eating her core, but En, who did not want to attack because of his memories, returns to reality and tries to help his friend.

During the battle, Sin grows wings and a tail, throwing the heroes away. Uzi drags En into the laboratory building and hides there with him. But Sin, hearing Vi, with the help of a hologram becomes En and she almost manages to lure her, but unexpectedly the real En shouts for her to stop, thereby giving their location to Uzi. Again the chase begins, where Sin almost kills Vi, but Uzi is already "ready" and does not obey Sin. Two on three - the final battle begins. Sin throws Vi and En away to kill the last obstacle in her path.

The Calculator tries to teleport behind Uzi, but the latter notices this in time due to the interference covering Sin's body.

She turns around and extends her arm forward, causing it to end up inside Shin's body, squeezing her core. Uzi rips out the core, and uses NULL to blast a hole through the planet for the star's rays to burn away the core, releasing the black hole trapped inside. Shin's body tries to swallow it with its last strength, but Uzi beats it to it, eating it herself. Eventually, Shin's body, deprived of its power source, falls to its knees, powerless, and begins to melt under the ultraviolet radiation.
