From Halopedia, the Halo wiki
Adriana was born around 2511 and was abducted by the Office of Naval Intelligence to be conscripted into the SPARTAN-II program. She soon met Jai-006 while he was sneaking out. Noticing that he needed a lockpick, she gave him a stolen paperclip she had hidden under her tongue. The two became fast friends, and would repeatedly attempt to escape the compound together. Each attempt failed, Adriana and Jai simply adopted different and more effective escape strategies following each failure.
She attempted these escapes with Jai not to escape but as an act of rebellion against her instructors. Both Spartans were given the option to undergo selective memory loss and quit the Spartan program by Dr. Catherine Halsey. Adriana decided to stay as she had grown to like it, and it was for Adriana that Jai decided to stay with the program. She and Jai would attempt one more escape effort, but they both decided to turn back. Upon their return, she and Jai met a SPARTAN named Michael-120, who had recently stolen and destroyed a D77-TC Pelican dropship. Together, these Spartans would come together to form Gray Team, with Jai as the leader.
Battle of the Rubble
In 2535, Adriana and the other members of Gray Team were sent behind enemy lines in order to destroy the navigation data held by the survivors of Madrigal, a world in the 23 Librae system that had been glassed by the Covenant not long after Harvest. The survivors were living in the Rubble, an asteroid space station built by the insurrectionists orbiting Hesiod. A small fleet of Kig-Yar, lead by Reth, had created an alliance with the insurrectionists to trade weapons and slipspace drives. However, these Kig-Yar were ordered by the Prophet of Truth to steal data from the humans that would lead the Covenant to other human colonies and Earth.
Soon, the Kig-Yar betrayed the rebels and began to attack the Rubble. Adriana witnessed a firefight between some Kig-Yar and Melko Hollister and Ignatio Delgado. The Kig-Yar were attempting to steal the navigation data from the two. Melko was killed, but Adriana killed the Kig-Yar before they could finish off the wounded Ignatio. Before she left, Adriana gave him a beacon, which would send a signal to her team to retrieve the data if he should no longer be capable of keeping it safe. She then ordered him to keep Gray Team a secret from the Rubble Security Council. Later on, she attempted to learn information about the Kestrel, a freighter used by smuggler Peter Bonifacio, at the bar Eddie's In The Rock. She met with Delgado again, who was also attempted to find out about the Kestrel. Five rebels overheard their conversation and approached them. When the men attacked them, Adriana swiftly defeated the insurgents, with the help of Jai, and brought Delgado to Gray Team's ship, the Petya, to meet Mike. The Spartans reveal their intentions to Delgado, destroy any data that could lead to human colonies and disrupt the insurrectionists from the inside. As Delgado left, he was instructed to find out more about who in the Rubble Security Council is leaking information to the Kig-Yar.
While aboard the Petya, the Spartans were contacted by the Rubble's artificial intelligence, Juliana. Despite their attempts to originally prevent her from communicating, the Spartans eventually agreed to hear Juliana out. In exchange for defending the Rubble from the Covenant, Juliana agreed to give the Spartans the data they wanted.
After Delgado was wounded by the Covenant-sympathizer Peter Bonifacio and had the data stolen from him, Adriana and Mike pursued him to prevent him from giving the navigation data to the Kig-Yar. The two Spartans encountered the insurgent leaving the Rubble aboard his freighter, Distancia. Mike quickly disabled his ship and Adriana boarded the freighter. Aboard the ship, Adriana only found Sean Williams, Bonifacio's bodyguard. Bonifacio was inside an escape pod to hid from the Spartans. Bonifacio promised that he would tell the Spartans where he hid the data if they allowed him to escape, which they reluctantly agreed to. After retrieving the navigation data, Adriana returned to the Petya and the Spartans agreed to let the Kig-Yar betray and kill Bonifacio in time.
Battle of Metisette
To stop Reth's intentions of mass-breeding an Unggoy army, the UNSC and the insurgents work together to destroy the Kig-Yar base on the moon of Metisette. Juliana sent Jai and Adriana land on Metisette in HEVs to destroy the Kig-Yar's AA battery and sensor facility, along with several ODSTs from the UNSC Midsummer Night.
Unfortunately, Adriana landed among a large group of Unggoy. Using the emergency burst thruster on her HEV, she plowed through numerous Unggoy in her way. When that finally ran out, she switched to her battle rifle and an M41 rocket launcher. She attacked the Unggoy with the rocket launcher and had to discard it when it ran out of ammunition. Then, she sprinted to a larger capsule dropped by the UNSC, only to discover that it simply contained an M274 Mongoose. Adriana believed it to be useless, so instead she physically beat the Unggoy with it until the Mongoose broke apart. Eventually, she regrouped with her squad of ODSTs, only to discover that only six of the original sixteen had survived; the others killed by the Kig-Yar. Adriana and the ODSTs were able to attack and destroy the Kig-Yar AA defenses, while Jai and his ODST squadron destroyed the sensor station. Without the sensor station or the AA battery, the Kig-Yar are powerless as Juliana systematically bombards their base with the Rubble's asteroids. Eventually, the Spartans were picked up by Delgado in a Pelican and they returned to the remains of the Rubble. All remaining UNSC and insurgent personnel were lead to the Exodus asteroid or aboard the Midsummer Night. The asteroid, powered by slipspace drives, and the frigate escaped into slipspace to escape a large Covenant fleet entering the system.
The Exodus asteroid and the Midsummer Night safely arrived at the 18 Scorpii system. The asteroid's inhabitants are safely evacuated before the asteroid shakes itself to pieces while in orbit around the human colony of Falaknuma. After, Adriana and Gray Team meet with Admiral Preston Cole and Commander Hadley who grants them the use of a UNSC Prowler, as the Petya was abandoned in the 23 Librae system. Hadley gave the Spartans new orders to venture even further into enemy lines, much to the satisfaction of the Spartans. After the events in The Rubble, Gray Team spent a majority of the Human-Covenant War behind enemy lines, often targeting and assassinating prominent commanders and religious leaders.
Late Human-Covenant War and Operation: SUNSPEAR
In 2551, Adrianna and the rest of Gray Team was deemed too inaccessible to be recalled to Reach. They were not present when the Covenant invaded the planet, having been out of contact for about a year. This was not cause for undue concern, as many of Gray Team's missions had been executed in a similar fashion.
After Reach fell to the Covenant in 2552 and the extinction of humanity seemed imminent, the Office of Naval Intelligence deployed Adriana and Gray Team on a mission to retaliate against Sangheili Fleetmasters who had glassed human worlds. The mission, dubbed Operation: SUNSPEAR, had Gray Team traveling to the Sangheili colony world of Glyke in a Prowler and destroying it with a NOVA bomb. As they were traveling to Glyke, Gray Team received a Condition Endgame order which stated that the Covenant had discovered the Sol system and had launched an attack. After this point, their Prowler's long-range communication equipment had been damaged, cutting them off from the wider UNSC. After arriving at Glyke with no knowledge that the war had ended, Gray Team voted to detonate the NOVA bomb, despite evidently not coming to a unanimous consensus. They landed on this surface to some opposition, planted the device, and retreated back into orbit to observe the detonation. The explosion completely destroyed Glyke and severely damaged Gray Team's Prowler, forcing them to evacuate in a Bumblebee escape craft. After a few days of waiting for retrieval, Adriana and the rest of Gray Team entered Cryo chambers and entered cryosleep in hopes of being retrieved by friendly forces. After several years, they were recovered in the debris field of Glyke by Rojka 'Kasaan and stored on board the Unwavering Discipline until their fates were decided by Rojka.
Awakening and Escape
In 2558 at the onset of the Carrow Conflict, Adrianna and the rest of Gray Team were released from their cryo chambers by UEG envoy Melody Azikiwe while the Unwavering Discipline was being boarded by Thars 'Sarov's forces. They were then attacked by Rojka Mrata, the latter of them being killed by Adrianna. Gray Team then recovered their Bumblebee escape craft from a hanger and escaped the ship, with Adrianna killing several of Thar's soldiers along the way and securing two plasma rifles. She then survived the Bumblebee's crash landing in the Uldt Desert and helped push the wreck into an oasis in order to smother a fire.
The Uldt Desert and Gila Station
After learning more of the post-war situation from a recently awoken Melody, Gray Team began traveling on foot towards Gila Station in the northern part of the Karfu Mountains. Adrianna hung back during this trip, refusing to conversate with her squadmates in the wake of Operation: SUNSPEAR. Ninty-six kilometers out from their destination, Gray Team was engaged by a Banshee, which they promptly destroyed. Arriving at Gila Station, they were admitted into the facility by Commander Greg van Eekhout, whose pleasant demeanor earned the team's distrust. As such, Adrianna distracted Van Eekhout by joining him for a drink while Jai and Mike respectively stayed with Melody and scouted the facility. Afterward, Gray Team confronted Melody and Van Eekhout over being deployed into the Carrow Conflict, with Adrianna expressing a great reluctance to take orders from ONI. This led to the team discussing Operation: SUNSPEAR for the first time since they carried it out. They were then briefed by Melody and Van Eekhout on the threat posed by the Jiralhanae Chieftain Hekabe and the Sharquoi situated below Suraka. Sometime after the briefing, Gila Station was attacked by a Sangheili assault team led by Thars. Adrianna and the rest of Gray Team were ordered to leave Melody and Van Eekhout behind and take the station's Warthog to Suraka to assist in the fight. They briefly discussed if they should return to the station to save Melody, but ultimately decided that the situation in Suraka was more important.
Ten minutes outside of the city, Gray Team was engaged by one of Thar's Banshees, which Adrianna eventually destroyed with the Warthog's M41 Vulcan chaingun. During this skirmish, they witnessed human ships making their attack run as a part of Operation: BUZZHAWK and felt the subsequent crash of the destroyed Varric-pattern heavy cruiser Foebane. They were then engaged by two Voice of Maardoth Banshees. Adriana took out one before the other was destroyed by a squad of Surakan Militia Volunteers soldiers. This squad, led by Sergeant Rae Carson, took Gray Team to a bunker where they allowed themselves to be detained as a show of good faith, despite Adrianna's growing impatience. They then waited to relay their information regarding the Sharquoi to the Surakan leadership. After the initial Sharquoi attack, they were moved to a different bunker on the outskirts of the city where they were questioned by Governor Ellis Gass and Vice-governor Lamar Edwards. From this exchange, a plan to assassinate Hekabe was put into motion. Before they started the operation, Gray Team was joined by Rojka and his remaining forces, who had recovered Melody from Gila Station and pledged themselves to fight against Hekabe and the Sharquoi. Both groups were deployed alongside Sergeant Carson's squad to skyscrapers overlooking the crater where Hekabe was commanding the Sharquoi, with Adrianna taking the shot on Hekabe with a SRS99-AM sniper rifle provided by the militia. She shot him cleanly through the head, but he was saved by the vertex and continued controlling the Sharquoi.
Ambush on Thars
After the assassination attempt failed, Gray Team retrieved Rojka and fled the building in a Pelican dropship, witnessing the detonation of a dozen Surakan thermobaric mines around the edge of the crater and a portion of the Sharquoi retreating back into the Forerunner facility at the center of the crater. They were then transported to the Surakan command bunker, where they devised a plan with Rojka to engage Thars and force him to keep his fleet from falling into the hands of the Sharquoi. They secured a Pelican and traveled into the Uldt Desert along with Melody in order to meet with Thars in a faux prisoner transfer and duel between the two Sangheili. They were able to ambush Thars and his forces with the help of Rojka's last surviving warriors. However, the Spirit dropship that Gray Team intended to capture and take to the rival Sangheili's fleet was destroyed in the battle, leaving them powerless to stop the Sharquoi from taking over Thar's fleet.
Battle of the Sharquoi Hive
Gray Team, Rojka, and Melody were then met by Ellis, who laid out a plan for defeating Hekabe and his forces. She had rigged a M68 Gauss cannon with a HAVOK tactical nuclear weapon as a power source, creating a device that fired a concentrated Electromagnetic pulse. This blast would neutralize the vertex, leaving Hekabe unable to command the Sharquoi. Gray Team then refined the plan, suggesting that they enter the Forerunner facility via aerial insertion and mount the device on a M121 Jackrabbit as opposed to a Warthog. The team was deployed into the structure alongside a militia squad led by Corporal Wyse, with Adrianna dropping with Melody strapped to her back. After reaching the bottom of the facility, she climbed onto the Jackrabbit as they crossed a bridge that led to Hekabe's position. She then engaged several Sharquoi as they progressed forward. After a falling Sharquoi immobilized the Jackrabbit, Adrianna and Mike provided covering fire as Jai removed the device from its mount and carried it towards Hekbe's position. After Ellis fired the device and took control of the vertex for herself, Adrianna, the rest of Gray Team, and Rojka were then immobilized by Sharquoi who were under her control. Ellis informed them that she planned to detonate the nuke and they all had ten minutes to evacuate the facility. The team fled up the stairs, with Adrianna stating that she felt uncomfortable being unarmed in that situation. A ways from the entrance to the facility, the team was picked up by a Pelican that was hailed for them by Ellis. They were able to escape the nuclear blast, though their Pelican was caught in the shockwave and crashed with no casualties.
Rejoining the UNSC
After a UNSC force arrived on Carrow, Gray Team and Melody were taken aboard the UNSC Welcome to the Snipehunt and received a hero's welcome from the crew while exiting their Pelican. They then were escorted to a meeting with ONI Commander Ivrin Yarick, where Melody was dismissed from ONI service. Yarick then offered Mike and the rest of Gray Team a choice: either allow their unit to be decommissioned and assigned to other areas of the UNSC's operation, or they could continue to operate under ONI's supervision as a part of an interspecies strike force consisting of members of the Swords of Sanghelios. They collectively chose the latter option, with Adrianna requesting an extensive list of weaponry as a condition of the squad's involvement in the operation. Adrianna and the rest of Gray Team are now stationed on the Winter-class prowler UNSC Perilous Contest as a part of this strike team.
Personality and traits
Adriana displays personality traits that are uncommon among Spartan-IIs. Where most Spartans adhere strictly to protocol and the chain of command, Adriana does not. She is not above openly questioning her commanding officer, or even contemplating taking a UNSC Prowler without clearance. A notably deadly sniper, Adriana was considered the muscle of Gray Team. Also, she does not appear to mind being out of her armor, whereas most other Spartans say that they feel exposed when they are not in their armor. Like the rest of Gray Team, Adriana enjoyed dangerous, difficult and life-risking missions behind enemy lines. As a child during the Spartan training, Adriana became friends with Jai-006 and the two would often escape training compounds on Reach just for the thrill, rather than actually attempting to abandon the project.
She had an apparent favoritism of Ignatio Delgado, which Jai disapproved of. She felt the need to protect the humans on the Rubble, even if there were collaborating with the Covenant, as she suspected that the Kig-Yar would betray them.
In the wake of Operation: SUNSPEAR, Adrianna's appearance and personality changed significantly. Her armor had been significantly damaged during combat on Glyke, with pronounced burns on the back of her greaves. She was profoundly impacted by the events and aftermath of the last mission, refusing to speak with and expressing hostility towards her teammates in non-combat situations. She also appeared detached from the surrounding environment as a whole. She seemed to shed some of her hostility and detachment by the end of the Carrow Conflict.
She may be of Eastern European descent, judging by her pronounced Slavic accent.
