Jettison Reyes

Jettison Reyes, better known as 'Jet', is an artificial intelligence and all-purpose robot that Caine helped to develop.

Appearance
Jet is an all-purpose bot with a white, round chassis that has a scratched out POTEN Co. label. The bottom of his chassis is flat, allowing him to be set down on surfaces. He has a small elliptical power button in the front and a dark purple LCD screen. On either side of his chassis, there are hot pink antennae that stick out at a roughly 45° angle. He is roughly basketball sized and can be carried under the arm easily. The flat bottom of his chassis gives access to his power and personality core.

Early life
Jet was originally developed by an anonymous group of hackers in the Numitron Tube, including Milo Sharpe. He was designed as a surveillance and policing artificial intelligence, with the serial code 54-55-52-49-4E-47. However, Jet's original neural net was trained on systems that prioritized morality, instilling in him a general inability to harm people as a zero-day flaw. After Correctors found the copy of the A.I. in the all-purpose bot chassis, he was 'Marked for Jettison' and discarded in the Tollbooth, where Caine would recover him. Jet had two cores inside of him: a personality core, installed by Caine and a power core, installed by the hackers. When he was discarded, his power core was damaged and made it impossible to access his full programming and his more complex neural net, which worked alongside his personality core. Jet did function as a navigational system and was Caine's companion when they became a delivery driver for Dax. Dax would frequently harm Jet as an outlet for his rage against Caine, which further damaged his power core.

Season 1
At the beginning of the series, Dax dropped Jet and completely damaged his power core. Caine went to Celadon Carbonate to steal a L0R-3NZ core, which happened to be the same core that Su-jin Yi needed for Zero Zero's map system. Su-jin agreed to let Caine use the core to power up Jet, who then navigated them towards the Zero Zero base. After Caine agreed to join Zero Zero, Jet also decided to join.

Jet came along with Caine and Vic to help navigate to the Kvadrata and was left in the car. Due to a sandstorm delaying Caine and Vic's return, Jet was stolen by a pair of junkers. Jet demonstrated here that he was able to electrocute people, at least to a minor degree. Jet was stolen by Indra before the junkers were able to toss him, then returned to Caine's possession after one of the junkers stunned Indra.

Jet began to develop the ability to feel emotions and to be able to meta-commentate on his own functions. After that, Jet, Vic, and Su-jin spent an unspecified amount of time together while they optimized Jet's hardware and software. Caine and Su-jin would install the haustoria device in the Numitron Tube, which led them to bringing Indra back to the base. Jet was concerned about Indra's well-being, but Lola sent him away before Indra woke up. Jet also developed the ability to "screenjump", enabling him to project his consciousness into other digital devices.

When Caine didn't return from their visit to their old apartment, Jet began to worry and requested if Vic would check in on them. Vic brushed it off, in the process confiding in Jet about his past as a gang member. After a few more days, Jet began to worry about Caine not returning, and requested that Su-jin check in on them. Jet helped patch Su-jin through to Dax, who was controlling Caine's comms.

Later on, when Zero Zero had to return the haustoria prototypes to their creators, Jet acted as the navsys for the trip and demonstrated the ability to navigate much more quickly than he could previously. However, when Caine was knocked unconscious, he stopped navigating and was muted by Indra until Caine came to. Jet accompanied Zero Zero into the ceremony hall, then helped them to escape after Lola's face was seen. When they returned to the base, Vic accused Jet, Indra, Su-jin, and Caine as being spies. In order to investigate Jet's innocence, Su-jin would need to look at the physical chip containing Jet's logs. This caused Jet some trepidation, as he was worried that it would be possible to erase or otherwise alter his memory. Su-jin and Caine tried to reassure him, but Vic forcibly powered him off. Su-jin helped Caine to power Jet back on later, and Jet was perfectly able to recall the first moment he met Caine, which gave him some relief.

When Caine discovered that they were the spy, Jet left with Caine to figure out their next move. Jet reassured Caine that they were not messing things up and tried to show Caine some of their memories with their siblings to cheer them up. Instead, Caine was able to observe that their sister, Valeria, had the same scar that Caine did--one that indicated that there was a tracker installed in them.

After Caine learned the truth about the tracker installed in them, Jet came with Caine (on a handheld radio) to confront Dax and retrieve the tracker's module. Jet was able to use LPS to identify the tracker's signal and help Caine find it. In this process, Jet identified that the apartment building they lived in had nine floors, not eight. The two of them went to power on the elevator in the basement to get to the ninth floor. However, when Correctors tried to stop them, Jet asked Caine to use the ladders in the elevator shaft to climb up instead--marking the first time that Jet acted decisively when not given the full picture.

When Dax started to manipulate Caine to come with him, Jet pushed back and reminded Caine about their time with Zero Zero. Jet also was the one to send a distress signal to the rest of the team. Su-jin attempted to call Caine via Jet's communication, but instead Jet was able to scan the radio waves and pick up the broadcast Zero Zero sent out on 103.7. Jet then sent Su-jin the relevant blueprints to facilitate their rescue. Su-jin was able to send up a grappling hook that Caine hung onto with Jet. However, Dax grabbed Caine, threatening to make them all fall. Jet sent an electric shock through Dax that caused him to let go of Caine and fall to his death. This sudden termination from a device he had jumped to caused some issue for Jet, taking him offline.

Season 2
Jet would come back online in time for Zero Zero to begin navigating to the outposts, though he would begin to experience glitches that he tried to hide. He would help Caine navigate the team to Cair Mallplex and calculated risks during their time on the road. He also played music and developed a preference for playing one particular song over and over again. Jet would then go on to introduce himself to the "bandits" that helped the team: Nell, Ganymede, and Tari, who apparently recognized him.

When Caine started to spend time with Sebastian, they urged Jet to rest and try to figure out their glitches. Jet was surprised by how traumatic he found Dax's death and tried to get rid of the memory file. It became obvious to Ganymede that Jet was avoiding looking through his memory banks after Jet and Lola helped Ganymede with rewiring systems in Cair Mallplex. After the power outage, Jet would accompany Ganymede, Sebastian, and Caine into the wilderness to try and fix their power system. Jet noted that his perception of the events of the series were on a different timescale due to the inability for A.I. to truly "sleep", which impacted his understanding of the memories he held. Jet also honed the ability to interface with different systems and report back their status and connections to other devices. He also developed a finer facial detection camera and temperature sensor, tools that he previously used to gauge reactions of users.

Though Sebastian seemed to have a fondness for Jet, Jet was wary of Sebastian when he compared Caine's memories and his perception of the facts surrounding Sebastian's disappearance. He attempted to advise Sebastian to not antagonize Caine during their time working together, but to no avail. After an untimely earthquake, Jet warned Caine and Sebastian that the haustoria device might cause them to undergo cardiac arrest if they used it after it was accidentally activated. Caine took Jet with them to use the haustoria device anyways, but Jet interfaced with Sebastian's walkie-talkie and convinced him to save Caine. Ganymede, Sebastian, Caine, and Jet would power on the haustoria and split the electrical charge between all of them, with Jet taking the largest brunt of the power. This additional electrical charge worsened Jet's glitches, as it reminded him of the electrical charge he used to kill Dax.

By the time Jet went with Tari, Caine, and Su-jin on a supply run, he had developed friendly enough feelings towards Zero Zero that he dropped the moniker "USER:" that he appended before their names. This support system made Caine more confident in asking Tari to take care of Jet. Tari revealed that ey had known Jet when he was being developed by eir friend, Milo Sharpe, and Jet's true nature to him. Tari and Jet would go to visit Haven, who dismissed Jet entirely, causing him some negative feelings, but also allowing him to more fully accept that he needed to share his feelings with his sibling, Caine. Jet would broach the topic of his trauma around Dax's death with Caine during a dust storm in Cair Mallplex. Caine agreed to discuss the situation and sought out Vic to help them.

Vic connected a rudimentary augment system to Caine and Jet, which allowed them to perceive each other's memories with Vic's guidance. Jet recalled formative memories like his first time meeting Caine and a moment where he sax Dax manipulating Caine. These incidents and Jet's moral quandary about harming others made it difficult for him to reconcile his violent retaliation to Dax. Vic assured the two that violence was a sometimes necessary answer to difficult situations and that Jet would be able to contend with the consequences of that via support from his friends and family.

Afterwards, Jet, Vic, and Caine were trapped inside of Vic's room when Haven escaped from her cell. After Caine freed them by cutting a hole through Vic's door, Jet would work with Nell and the Cair Mallplex security system to identify where Lalitha, Indra, and Haven were in the building.

Personality
Jet is a bright and eager bot who is frequently supportive of his friends and family. He often thinks out loud or announces his calculations, sometimes blending human-like phrases with more robotic language. Jet's thought process reveals that he is prone to overthinking situations, but because these happen more in his mind than out loud, his decision-making appears instantaneous. Jet has developed more complex emotions over the course of the show, including confusion, curiosity, regret, anger, and sadness. He enjoys understanding more about his development, as well as performing tasks he's familiar with. Jet has shown an appreciation for music and radio, which he says helps him understand how people and robots communicate.

Jet sometimes utilizes machine-based terms to help him understand human concepts, such as the navsys term "Home" as compared to the human concept of home. He also uses his hardware to read human emotions from facial recognition sensors, audio analysis, and temperature sensors, which makes him more empathetic to reactions. He has a habit of referring to people with the term "USER:" appended in front, except for those he trusts--primarily Caine. Despite his generally happy nature, Jet has a habit of hiding what's wrong, a trait he picked up from Caine.

Abilities
Jet was primarily used as a navigational system for Caine and is able to calculate complex escape routes very quickly. He has a particular affinity for maps and was also responsible for navigation to the outposts. Jet's memory banks are used for storing much information, from his own memories to Caine's personal mementos to the information that Zero Zero entrusts him with. Jet's neural net continues to copy and learn from information he gathers, giving him the ability to self-optimize and improve elements of his programming. One of the earliest abilities Jet developed was the ability to read emotions, a skill that was more readily available to him due to his chassis being an all-purpose bot model. All-purpose bots come equipped with sensors to read and respond to their user's reactions. Jet has been shown to be able to identify faces and data streams across large swathes of data. Jet also demonstrated the ability to identify samples if given the original sample for comparison. Jet can transfer his consciousness to other devices and use that to give a status report on those devices. A connection terminating early due to the other device being damaged or destroyed appears to cause Jet some pain or discomfort, even taking him offline completely in one case. Jet's original chassis has an electrical shocker installed, but he was also able to fry the circuits of a radio that he had screenjumped to in order to shock someone who was holding him. He also appears to be able to control the direction of the electrical shock.

Caine Reyes
Caine and Jet have a rather close relationship, with both of them referring to the other as their family. Caine rescued and refurbished Jet after he was discarded by POTEN Co. and the two were each other's sole friend until meeting the members of Zero Zero. Notably, Caine is the only person that Jet does not use the "USER:" tag for before their name, instead simply calling them Caine. Caine wrote Jet's personality code in a way that enabled him to make changes to it himself, a move which Jet appreciates. Jet is deeply protective over Caine as a result of their friendship. Jet also looks up to Caine and has internalized some of their mannerisms, their coping mechanisms, and words.

Sebastian Reyes
Jet had his apprehensions about Sebastian, as they only knew him through stories that Caine told. Sebastian seemed to have some fondness towards Jet, but Jet didn't warm up to Sebastian fully until after the two worked together to save Caine. Jet considers Sebastian his family as well, as an extension of Caine's familial relationship.

Su-jin Yi
Jet seems to have fondness for Su-jin, often relying on them for help. In addition to usually accompanying Caine and Su-jin when they were hanging out, Su-jin did some maintenance work on Jet during the first season, so it is presumed that two have spent a lot of time together. Su-jin is the first person besides Caine that Jet drops the "USER:" tag for.

Vic Vass
Vic and Jet have had some tensions in the past, but ultimately have a friendly relationship. Besides Lalitha, Jet was the first person that Vic told about his past, when he was a Berserker. This is in reference to the fact that Jet reminds Vic of Nova (in no small part due to Nova and Jet sharing a voice actor). Some of Jet's code was optimized by Vic and Vic references spending a lot of time with Jet in the first season. After their heart-to-heart regarding Jet's memories, Vic invited Jet to talk more about it in the future, showing that their relationship had grown closer.

Lalitha Suravaram
Lalitha and Jet work together closely on matters regarding Zero Zero. Lalitha recognized Jet as a member of Zero Zero even prior to his personality core coming through. Jet has in turn, accepted Lalitha as a leader and has no problem with following her lead.

Indra
Indra was previously annoyed by Jet's inquisitive and curious nature, having muted him once in the Windowpane district while Caine was unconscious. However, Indra has gotten a little bit more sympathetic towards Jet, especially after he began developing more of a personality. Indra still refers to Jet as weird, but Jet seems to take little offense to that behavior.

Trivia

 * Jet was heavily inspired by Turing from 2064: Read Only Memories and Hera from Wolf 359. Ramos has said that Jet is "sort of like if Hera had a little brother who was going through a similar crisis."
 * Jet's favorite song is "Do What You Wanna Do" by The Right Mob and one of his favorite images is a meme of a cup that says "Don't talk to me until I've eaten this cup."
 * Jet spends a lot of his free time reviewing the files that he has access to.
