Juliet (AI)

Juliet, UNSC AI serial number JLT 8011-10, is a fifth-generation "smart" Artificial Intelligence construct, and SPARTAN-091's personal companion. She has been in most of the battles he has, experienced the same feelings and emotions he has, and can officially be termed "rampant" by most AI technicians.
==Overview==
===History===
Juliet is a smart A.I., but is also one of the first "infinity code" hybrid AIs to be put on the frontlines of UNSC-Covenant conflicts. Her creator, Janine Darc, upon whose cloned brain Juliet is based, had discovered a strange piece of data in the memory core of a recovered Forerunner Sentinel. This data, referred to as the "infinity code," allowed Forerunner constructs to self-repair to the point that their effective lifespans were virtually indefinite. Juliet, having this advanced data spliced into her own coding, is capable of a maximum lifespan of about 225 years.
Not only does this Forerunner programming boost Juliet's lifespan, it also considerably upgrades her processing speed, allowing her to process incoming data at the rate of 20 petabytes/second, and making her one of the fastest AIs available to UNSC forces. 
She is programmed with information on the controls of most Human, Covenant, and Forerunner vehicles, and can easily pilot these craft in case of the pilot's inability to do so. She is not designed specifically for infiltration, and is not as good as her "cousin" Cortana, when it comes to this area, but has repeatedly stated that she thinks she does a good job anyway.
Juliet specializes in battlefield assistance and ship-to-ship combat. Her radar and motion-tracker optimization and interface subroutines are built to the highest specifications available, and this advanced early-warning system has allowed her host, Jared-091, to survive many life-threatening conflicts.
ONI issued an order to recall Juliet from Jared several years after the Human-Covenant War ended, attempting to retrieve the AI from his mind with a specialzed probe. The effort failed. and Juliet deleted her weakened behaviorial inhibitions and grafted herself into Jared's neural implant, making herself a permanent part of his augmented mind. Thankfully, Jared was unharmed, and the two still get along quite well.
As the Remnant campaign began, Juliet could be classified as sentient, one of the few AI to shed her programmming bonds and not subsequently and immediately go rampant. She enjoys this distinction, and calls herself one of "the world's first non-corporeal citizens."
===Personality===
Juliet likes to refer to herself as "cute" and "perky", but is mainly known for her extremely sarcastic sense of humor, a trait she seemed to have been "born" with. This nonstandard behavior has only gotten worse from her work with UNSC ODSTs, and subsequent assignment to Jared-091. Although eager to help, she is not afraid to make her opinions known, frequently in a manner that many would describe as less than polite. The Office of Naval Intelligence has earned her undying emnity for attempting to remove her from service, and she has more than once refused to work with ONI AIs. This hatred only grew during the time that she and Jared worked with ONI's operative Talon, a girl who had been abused by the Office. By the time of the Remnant campaign, Juliet had constructed several hundred highly-potent viruses specifically designed to wreak havoc on the Office's intelligence networks. However, she has never used them, as she considers herself "too much of a good person."
===Appearance===
Juliet prefers to appear as a slim indigo- and cyan-colored female human with aesthetic wings on her back. These wings were her own modification that appeared at an unknown point in her duty cycle. She calls this form "my angelic nature brought to life" and appears to enjoy the occasional lingering glances she sometimes receives from UNSC personnel.
===Relationship to Other AIs===
Juliet, being an older model of AI than her Thirteenth-generation predecessors during the Monolith conflict, is looked on a something of a relic, old but still useful. She hates this view, and tries to avoid contact with most Thirteenth-gen AIs, save for business purposes.
===Relationship to Humans===
Juliet's long relationship with her host is quite intimate, given that she literally lives within his mind. She enjoys teasing him about their "romance," and has been heard to say that her host is "her boy," though the relationship is by its nature more complex than this. While Jared would never admit anything like this, their close bond and dependence upon each other has made him feel the same about her, as the two are the closest thing each has to a best friend. Literally and figuratively inseparable, they have been friends ever since their first meeting at the Battle of Manheim. 
Juliet exhibits many tendencies and traits that many AI researchers would classify as rampant, though these are underreported, as SPARTAN-091 has never logged them. They have on occasion been noticed by others who have worked with more standard AIs. Now that Juliet is a permanent fixture of his mind, the two work as close as ever.
Juliet has a motherly affection for all of her counterpart's SPARTAN-IV trainees, and worries about them constantly when they are assigned to missions beyond Human space.
