Black-Box

"They don't have AIs like me. Well, nobody does, because I'm unparalleled magnificence."

- Black-Box

Black-Box (AI serial number: BBX 8995-1), commonly referred to as "BB", is a fourth-generation "smart" artificial intelligence construct built by the United Nations Space Command. He is under the supervision of the Office of Naval Intelligence and was the personal assistant to then-Rear Admiral Serin Osman during her command of Kilo-Five, a highly covert intelligence unit under the direct authority of Admiral Margaret Parangosky, CINCONI.

Creation
Black-Box was created from the brain of Dr. Graham Alban, a senior researcher associated with ONI Special Research, and close friend of Admiral Margaret Parangosky. Alban had committed suicide out of guilt for his part in the SPARTAN-II program, and had requested that his brain be kept for the AI donor program. Black-Box was to be the personal AI companion for Parangosky in August 2552. He later sent a fragment of himself aboard the as it was sent to Onyx in wake of the planet's destruction. He then picked up massive Slipspace readings and the transponder of the late Kurt Ambrose.

Kilo-Five
On January 26, 2553, BB observed David Agnoli and Captain Serin Osman in section Core 5 of HIGHCOM Facility Bravo-6. When Osman was called in to see Admiral Parangosky, he introduced himself to her and accompanied her to Parangosky's office. There Parangosky assigned BB to Osman and her black-ops team Kilo-Five, which was tasked with creating Sangheili insurrection and locating Catherine Halsey on Onyx. He later introduced himself to the other members of the team, professor Evan Phillips, ODSTs Staff Sergeant "Mal" Geffen, Sergeant Lian Devereaux, Corporal "Vaz" Beloi, and SPARTAN-II Naomi-010. He was put aboard the where he monitored the Orbital Drop Shock Troopers' body signals, deducing that they were excited to have their own rooms.

BB primarily took on a side role on the first three missions enacted by Kilo-Five. During their weapons exchange with Avu Med 'Telcam on New Llanelli, he scanned 'Telcam's ships. As they got back on the ship, Black-Box let his dumb AI functions run the ship while he listened to numerous comms channels at once. Mainly taking a managerial role on the extraction of Mike Spenser, monitoring the until the lack of help from Venezia led to the death of all aboard when it was destroyed.

BB later checked on Captain Damien Hogarth through his fragment he had left in ONI's system back at Bravo-6. Hogarth was using his personal AI, Harriet, to dig up dirt on Parangosky so that he could eventually usurp her position as ONI director. While at first offended that Hogarth thought Harriet could get past him, he decided to feed her false information instead to "ruin Hogarth's day". As the attempted intrusions continued, Black-Box accessed Hogarth's files and triggered a false "massive overspending" alert to UNSC Internal Audit as retribution.

Later, Black-Box assisted Kilo-Five with seizing the Covenant cargo ship Piety and successfully captured an onboard Huragok, Requires Adjustment. BB went on several missions aiding the Servants of the Abiding Truth and continuing the insurrection against Arbiter Thel 'Vadam. Later on, Kilo-Five entered Shield World 006, a Forerunner Dyson sphere, and recovered the human survivors inside while arresting Dr. Halsey under orders from Admiral Parangosky. Having learned the tragic truth behind the Spartan-IIs and the fate of their parents, Vaz approached Dr. Halsey’s compartment in an attempt to kill her but was convinced by BB to walk away.

Sanghelios fragment
In March 2553, shortly after the recovery of the shield world survivors, Evan Phillips, accompanied with a fragment of BB, left Kilo-Five to study Sangheili culture on Sanghelios. While touring the state of Ontom, he met with Avu Med 'Telcam. As they approached the entrance of the Temple of the Abiding Truth, they were caught in the midst of a bombing orchestrated by Jiralhanae dissidents. Back on Port Stanley, BB's cam feed on Phillips was lost, but BB detected that Phillips was still alive. Following a second explosion, BB immediately experienced damaging pain. Captain Osman ordered the retrieval of Phillips and prepared the ship for a slipspace jump back to Sanghelios.

In the wake of the Jiralhanae uprising, 'Telcam planned to launch his attack on the state of Vadam. Phillips was taken into the custody of the Abiding Truth, who permitted him to explore the interior of the Forerunner temple. As Phillips explored the structure, he noted that the micro-camera unit on his shirt, which contained BB's fragment, had been peppered with shrapnel. The placement of the unit had saved Phillips' life, but BB's fragment inside had taken damage and activated an emergency purge function, wiping important data and higher personality functions from the AI's memory. While BB's fragment was far less useful in this state, Phillips nonetheless was able to use him to aid in translating certain symbols inside the structure. The data they collected inside was soon speculated to be the locations and operational statuses of the remaining Halo installations. Phillips and the BB fragment eventually found their way to a room with a translocation portal. Solving an arum-like activation system, Phillips was translocated to the portal's receiving end in Acroli.

During the battle over Sanghelios between the Arbiter's and the Abiding Truth's forces, with BB's help, Port Stanley posed as a Kig-Yar pirate ship. Disguised a Shipmistress named "Lahz", Osman and BB covertly destroyed some of 'Vadam's ships, leaving the Arbiter with a Pyrrhic victory. During this time, BB and Osman learned that a T'vaoan pirate named Sav Fel had stolen the battlecruiser Pious Inquisitor from the Abiding Truth.

After Phillips was rescued from the Nes'alun keep by Kilo-Five, they visited over Sanghelios. The primary BB faced somewhat of an internal crisis about the reintegration of his damaged fragment into his core matrix. Phillips and BB reluctantly went to see Dr. Catherine Halsey, then aboard Infinity, and asked her if she could help Black-Box. However, the Doctor stated that there was no solution at the moment. After Dr. Halsey failed to assist BB, he successfully reintegrated by himself. Afterwards Phillips and BB tried to translate the Forerunner symbols they discovered from the Forerunner temple in Ontom.

Venezian movement
After the operation on Sanghelios, Kilo-Five were assigned to track down Naomi's father and known Venezian insurrectionist Staffan Sentzke, who was seen in the company of Sav Fel, the current owner of Pious Inquisitor. Shortly thereafter, Mal and Vaz landed on Venezia with the goal of joining the Venezian militia. Aboard the Port Stanley, Phillips and BB discussed previous events and BB admitted that he had come to terms with his broken fragment.

Once Mal and Vaz had infiltrated the militia, they were tasked with getting aboard the Pious Inquisitor and let BB insert one of his fragments into the systems, so they could take control of the ship. Although the two managed to get aboard the Inquisitor, their plan had become complicated when they learned that the Inquisitor had a Huragok, Sometimes Sinks, aboard the ship. Sinks would be able to detect BB if he was put into the ship's systems. Using a tracer planted by Vaz, BB attempted to remotely seize control of Pious Inquisitor from Venezia using a local slipspace communicator, but Sometimes Sinks detected and blocked the intrusion. Believing that they were responsible for the intrusion, Sentzke had Mal and Vaz captured and interrogated. Black-Box used Mal and Vaz's neural transponders to locate them on Venezia. Naomi took the team's new dropship, Bogof, to free Mal from the rebels' compound while Devereaux went after Vaz on Tart-Cart, also taking Sentzke prisoner. They return to the Port Stanley and Staffan Sentzke is soon allowed to reunite with his daughter. Wanting to find out more about her childhood, Naomi asked BB to connect with her neural implant and use ONI recordings to spark some of her long-forgotten memories. BB agreed to her request, although he acknoweledged the risk associated with such a procedure and the potential fallibility of the memories.

Pious Inquisitor
Meanwhile, a crew of Kig-Yar contracted by 'Telcam located and boarded Pious Inquisitor, attempting to commandeer the ship for themselves. Sometimes Sinks, distrustful of the Kig-Yar and only compliant to Sentzke's orders, placed the ship in complete lockdown. After Staffan convinced Sinks to allow Kilo-Five aboard the ship, the team worked to put BB into the Inquisitor's systems so he could take control of the ship. Once BB was placed into the ship's systems, he helped Kilo-Five make their way to the bridge, while taunting the Kig-Yar. With Mal and Naomi pressing on the bridge, the leader of the Kig-Yar privateers, Shipmistress Chol Von, set the ship to explode and escaped with her remaining crew. BB and Sinks worked to restore enough control to get everyone out.

While Kilo-Five escaped to their dropships, Sentzke took a Spirit from the shuttle bay but stayed in range to ensure Naomi was safe. Assuming Sentzke had no chance of surviving the explosion, Vaz told BB to send the ONI file on Naomi's kidnapping to Sentzke in the hope that he would manage to relay it his family and prove his theories right. While sending the files, BB personally appeared in Sentzke's Spirit. Immediately noticing the slipspace drive and deducing Sentzke's true intentions, the AI indicated that ONI would never cease hunting Sentzke if they knew he had survived. However, out of both sympathy and trust that Sentzke would stay true to his word and leave Earth alone, BB wiped his memory of the incident immediately afterward; this left Kilo-Five and ONI to assume that Sentzke had been killed in the explosion.

With Pious Inquisitor destroyed and the Venezian threat seemingly neutralized for the time being, Kilo-Five was granted shore leave on Cascade. At her request, BB allowed Osman to view her origins file.

Personality and traits
Possessing a male personality, Black-Box is noted as being incredibly egotistical and fully comfortable with being an entity of pure intellect, and has an innate sense of superiority over not only his human creators, but also other AIs. Due to this, Black-Box chooses not to represent himself with a humanoid avatar, as the majority of "smart" AIs do, and instead appears as a featureless box bathed in blue light; at times, it is mentioned that he uses the brightest side of the cube to indicate which way his avatar is facing. He has been described as deeply narcissistic, and has been noted to speak in a supercilious manner. He has also been noted as having a sarcastic sense of humor. Additionally, he tries not to get too invested in humans, such as he believes Cortana did.

Possibly due to his programming being based off the brain of Dr. Alban, Black-Box has intense antipathy and disgust for Catherine Halsey. As another remnant of his brain donor, BB also possesses a fascination for cognitive psychology and has a tendency of analyzing the behavior of humans and other species in depth.

Thanks to the UNSC's improved, Forerunner-enhanced communication systems, Black-Box is capable of distributing his processes across interstellar distances with no discernible lag. As such, he was capable of monitoring activity on Earth, Sanghelios, and several other locations with his primary matrix physically present on Port Stanley. While a "smart" AI, Black-Box possesses at his core a set of "dumb" processes, which can be separated from his higher thought processes and function as a "dumb" AI, operating independently of the main AI, but still fully within his awareness; he represents these processes as a battered and weathered version of his normal cube-shaped hologram self. Whether this is a trait unique to Black-Box is unknown.
