Adriana-111

Petty Officer Adriana-111 is a SPARTAN-II supersoldier and a member of the Gray Team.

Conscription
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 Mike-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 Black 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.

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 a 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.

Later career
In 2551, Adriana 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.

At some point, before the end of the war, Adriana and the rest of Gray Team got captured by unknown Elite fleetmaster and put in stasis on the planet Carrow, a world on the edge of the Joint Occupation Zone. They had been held there until 2558, when the Office of Naval Intelligence found out and sent Unified Earth Government envoy Melody Azikiwe to find a way to free the Spartans.

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. 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.

Trivia
She may be of Eastern European descent, judging by her pronounced Slavic accent.
