== Biography ==
===Conscription===
Olivia Tut was born on the [[human]] [[Inner Colonies|Inner Colony]] of [[Miridem]] on [[2538#September|September 26, 2538]].{{Ref/Reuse|Enc22}} She became orphaned at a young age, likely when [[Battle of Miridem|Miridem was]] [[glassing|glassed]] in [[2544]].{{Ref/Book|Id=Enc22P51|Enc22|Page=51}} Olivia later joined [[SPARTAN-III program|SPARTAN-III]] [[SPARTAN-III Gamma Company|Gamma Company]] at around age six when she,{{Ref/Reuse|hll}} along with other orphans, "volunteered" to become Spartans to avenge their families' deaths. She and the other Spartan-III candidates were trained under [[Senior Chief Petty Officer]] [[Franklin Mendez|Mendez]], surviving [[SPARTAN-III Beta Company|Beta Company]] SPARTAN-IIIs [[Lucy-B091]] and [[Tom-B292]], and [[SPARTAN-II program|SPARTAN-II]] [[Lieutenant Commander]] [[Kurt Ambrose]] at [[Camp Currahee]] on the planet [[Onyx]]. Olivia was assigned to [[Team Saber]] under the command of [[Ash-G099]].

===Onyx Conflict===
====Initial attack====
When the human forces on Onyx came under attack by [[Onyx Sentinel|Sentinels]] on [[2552#October|October 31, 2552]], the teams were still vying for top honors. Team Saber went dangerously close to the restricted [[Zone 67]] to avoid the other teams during a training exercise. There they spied what they assumed at the time to be a new kind of [[Covenant]] drone, based on its [[energy shielding]], and decided to investigate. The Sentinels quickly turned hostile, forcing the exercise to come to an abrupt halt.<ref>'''Halo: Ghosts of Onyx''', ''page 117-119''</ref>

Olivia remained with the team as they tried to figure out the drones' weak spots. She and the rest of the team hurled rocks at the drones and to their surprise, the drone's shields did not activate. One of the Sentinels chased Ash into a small ravine, but he was saved by the rest of the team, who pummeled the Sentinel with rocks, destroying it just in time.<ref>'''Halo: Ghosts of Onyx''', ''page 130-135''</ref>

====Regrouping with UNSC forces====
A general decision was made and the Team moved to the [[Camp Currahee]] armory to obtain heavier weapons. Team Saber met up with Commander Ambrose, CPO Mendez, Tom, and Lucy, and proceeded to engage the Sentinels with guerrilla tactics. Some time later, Olivia and the team met up with [[Kelly-087]] and [[Catherine Halsey|Dr. Catherine Halsey]] but had no time for pleasantries because they were soon engaged by a pair of Sentinels. After the skirmish was over, the team took Dr. Halsey and Kelly to a bombed-out bunker, while Olivia went out on watch. While in the bunker, Dr. Halsey revealed the origin of the Sentinels and what their next action should be.<ref>'''Halo: Ghosts of Onyx''', ''page 170-176''</ref>

Just as Team Saber was in the middle of battling the Sentinels, a Covenant dropship from the ''[[Bloodied Spirit]]'', carrying SPARTAN-II [[Blue Team]]—[[Frederic-104]], [[Linda-058]], and [[William-043]]—landed rather abruptly in the forest at the source of an emergency transmission sent out by the UNSC forces on Onyx.<ref>'''Halo: Ghosts of Onyx''', ''page 230''</ref> With the Sentinels increasing in number, Olivia and the others decided to retreat back to Zone 67. By now, the team had figured out that the Sentinels only come after them in pairs and there was always one observer that recorded all of the action and reported back to others, making the Sentinels smarter and harder to defeat each time they engaged in combat with the humans. Using Kelly as bait, they managed to trap a Sentinel pair in a tunnel, thereby buying themselves some time.<ref>'''Halo: Ghosts of Onyx''', ''page 261''</ref>

====Retreat into Zone 67====
Shortly thereafter, they moved into [[Zone 67]] and discovered an unearthed Forerunner city. Once there, they discovered the [[Cartographer|map room]] of Onyx and the location of [[Team Katana]], whose signal Olivia had picked up earlier before communications with them were lost.<ref>'''Halo: Ghosts of Onyx''', ''pages 131-132''</ref> Meanwhile, a [[Joyous Exultation Covenant|Covenant]] fleet led by [[Fleet Master]] [[Voro Nar 'Mantakree]] arrived at Onyx, dispatching forces after the Spartans. In looking in the map room and examining the Forerunner text, Dr. Halsey figured out how to utilize Onyx's [[slipspace translocation]] [[Teleportation grid|grid]], allowing them to easily move across the artificial world.<ref>'''Halo: Ghosts of Onyx''', ''pages 311''</ref>

Just before the team was about to jump to team Katana, Zone 67's AI [[Endless Summer]] contacted Dr. Halsey and Kurt-051, telling them they needed to destroy the [[Sentinel manufacturing facility]] in order to save [[Patterson's battle group|a UNSC battle group]] in orbit. After teleporting to the Sentinel factory near the northern pole of Onyx, Olivia and Team Saber used the facility's teleportation grid to an advantage, destroying three key structures by tricking Sentinels into firing on them in a line with the structures. Having successfully destabilized the factory's systems, they teleported away as the facility was destroyed.<ref>'''Halo: Ghosts of Onyx''', ''pages 313-324''</ref>

====End of the battle====
Olivia and the rest of the team translocated at Team Katana's holding area to find them in [[slipspace field pod]]s. By deciphering Forerunner glyphs, Dr. Halsey found out that there was a shelter known as a "[[shield world]]" in Onyx's core, and persuaded Kurt and the others to make their way to it. However, the Covenant knew the location of the group and was on the way with an entire armada of troops to attempt to stop them.<ref>'''Halo: Ghosts of Onyx''', ''pages 341-343''</ref>

After making their way into the [[Core room antechamber|core room of Onyx]], Olivia, along with the other Spartans, made a loose half-circle kill zone around the entrance to the shield world and picked off targets at range. They managed to defend the slipspace rift, although it had come at some serious losses; Will, [[Dante-G188|Dante]], and [[Holly-G003|Holly]] had already died at the hands of the Covenant.<ref>'''Halo: Ghosts of Onyx''', ''pages 360-362''</ref> As there was little time left and the Covenant forces were closing in for the final kill, Kurt ordered Olivia and the rest of Team Saber through the portal,<ref>'''Halo: Ghosts of Onyx''', ''page 365''</ref> while he stayed behind to detonate two [[FENRIS nuclear warhead]]s and deny the Covenant access to the shield world.<ref>'''Halo: Ghosts of Onyx''', ''page 372''</ref>

====Shield world====
{{quote|Welcome to Blue, Spartans. We're going to make a great team.|[[Kelly-087]] welcoming the Spartan-IIIs to Blue Team}}
On the other side of the slipspace rift, Olivia and the others found themselves inside a [[Trevelyan|Dyson sphere habitat]]. There, Olivia and the other survivors waited for Kurt to arrive, but he never came. Shortly afterward, they made gravestones for William, Dante, Kurt and Holly; Olivia was then accepted into [[Blue Team]], along with the other Spartan-IIIs present, by [[Kelly-087]] and [[Frederic-104]].{{Ref/Reuse|blue}}

Olivia and the other survivors then proceeded to explore the sphere in order to fulfill their mission to find valuable Forerunner technologies and take them back to Earth.{{Ref/Reuse|blue}} After they had reconnoitered the vast construct for some time and established a camp in a Forerunner structure, [[Lucy-B091]] discovered several [[Huragok]] which helped the human survivors contact the ONI ships outside and eventually disabled the [[slipspace bubble]], bringing the shield world into normal space. As the sphere had occupied a pocket of alternate space-time, Olivia and the others had only experienced the passage of several days, whereas over three months had passed in normal space-time.<ref>'''Halo: Glasslands''', ''page 382-389''</ref> After being retrieved by [[Kilo-Five]], Olivia and the others were taken to [[Earth]] aboard the {{UNSCShip|Port Stanley}} for a debriefing in [[HIGHCOM Facility Bravo-6]].<ref>'''Halo: Glasslands''', ''page 401''</ref>

Olivia and the other Spartan-III survivors of the Battle of Onyx continued to serve with Blue Team and embarked on several missions together.<ref name="hll">'''Halo: Last Light'''</ref>

===Gao===
{{Main|Operation: JOVIAN WHISTLE}}
In [[2553#May|May 2553]], Blue Team was attached to ONI's [[717th Xeno-Materials Exploitation Battalion]] deployed to the [[Outer Colony]] of [[Gao]] to search for a [[Forerunner]] [[ancilla]], [[Intrepid Eye]], that had been detected on the planet by the battalion's [[Commander]] [[Murtag Nelson]]. The UNSC's presence on the planet was largely undesired by the traditionally independent Gao. For over a month, the UNSC attempted to capture the ancilla, who, in turn, regularly harassed the 717th with her [[Aggressor Sentinel]]s. Additionally, upon learning of the UNSC's intentions, Intrepid Eye began covertly murdering Gao citizens in the [[Montero Cave System]] in an effort to create discord between the Gaos and the UNSC. The [[Gao Ministry of Protection]] dispatched [[Special inspector|Special Inspector]] [[Veta Lopis]] to find the murderer and Nelson had members of Blue Team aid her in her efforts to allow the UNSC to return searching for the ancilla without Gao interference. Lopis was initially convinced that the murderer was one of the Spartans, with her suspicions eventually focusing on Mark-G313 in particular.{{Ref/Reuse|hll}}

====Journey in the dark====
[[File:Halo Last Light cover.jpg|thumb|250px|Olivia, [[Frederic-104]], [[Special Inspector]] [[Veta Lopis]], [[Ash-G099]] and [[Mark-G313]] in [[Gao]]'s [[Montero Cave System]].]]
On [[2553#July|July 4, 2553]], Olivia, Ash, Mark, and Fred accompanied Lopis and her partner [[Cirilo]] to the last known location of [[Major]] [[Ira Halal]] and [[Private]] [[Hayes]], both of whom turned out to have been murdered. The Gao investigators decided to follow a trail of an unidentified fluid—in fact belonging to the wounded [[Huragok]] [[Roams Alone]]—deeper into the caverns, with the Spartans coming along. As they reached a large cavern, after nearly a twelve hours' descent, the humans were attacked by Intrepid Eye's last four remaining Sentinels. Though the Spartans were able to destroy the Forerunner drones, Cirilo was killed and Olivia was seriously wounded, with both of her legs broken by a large falling rock. Following her injury, she destroyed a Sentinel bare-handed in the berserk state experienced by members of Gamma Company under intense pain and stress due to their [[Project CHRYSANTHEMUM#Gamma Company|altered brain chemistry]]. With the engagement over, Fred left to reconnoiter the area in hopes of finding the [[Covert Support Base 4276|Forerunner base]] the 717th was searching for. While waiting for Fred, the Gammas and Lopis were approached by Roams Alone, a [[Lifeworker]] Huragok who began to heal Olivia's wounds.{{Ref/Reuse|hll}}

Fred eventually returned and decided that the party should take the Huragok with them, return to the surface and report to Nelson. However, Olivia had lost her "Smoothers"—drugs that controlled the Gammas' destabilizing augmentations—during the fighting, making it inevitable that the young Spartans would run out of them on the way out. Mark volunteered to take only one of the remaining five Smoother injections, leaving two doses each for Ash and Olivia, while Mark subsequently took point as the group began their climb toward the surface. While Roams Alone had improved Olivia's condition, she was still unable to move by herself and had to be carried on a litter.{{Ref/Reuse|hll}}

====Battle for Wendosa====
After over a day's climb, the party eventually reached the [[Gallery of the Inverted Forest]] where they were approached by a Forerunner [[inspection drone]] housing Intrepid Eye. While isolated from the others, Olivia and Lopis were confronted by [[Petora Zoyas]], who held Olivia at gunpoint and appeared to know Lopis, telling her that they should take both the Huragok and the Forerunner device with them and escape. Meanwhile, however, Fred used a [[scramble grenade]] on the inspection drone, generating a blinding flash of light; Olivia used this to an advantage and promptly killed Zoyas by stabbing the Gao insurgent in the chest with her [[combat knife]]. The incident made Olivia exceedingly distrustful of Lopis, convinced that the inspector was a spy in league with Zoyas.{{Ref/Reuse|hll}}

With the ancilla in their possession, the group surfaced at the embattled village of [[Wendosa]] and proceeded to reinforce the 717th, which was under attack by the [[Keepers of the One Freedom]]. Roams Alone having worked on her, Olivia was now able to move on her own and contribute to the fighting to some extent. Informed that Fred was to return to the [[Montero Vitality Center]] with the ancilla, the group fought their way through Wendosa and Fred boarded a [[UH-144 Falcon|Falcon]], but the craft was shot down and crashed in the jungle several [[kilometer]]s away. As the battle in Wendosa began to turn to the UNSC's favor, Olivia and the others reunited with the rest of Blue Team, who decided to make their way to the Falcon's crash site before the Keepers could reach it. Before they departed, the Gammas took double doses of Smoothers, stabilizing their mental condition. After a series of sniper battles along the [[Briones Ridge]], the group arrived at the crash site. With the eventual help of [[Alpha Company (717th)|Alpha Company]], they fended off the Keepers and recovered Fred as well as the ancilla. The Spartans were brought to the [[Montero Vitality Center]] to recover, with Olivia and Ash personally checking on Lopis after she regained consciousness.{{Ref/Reuse|hll}}

====Escape====
{{Quote|multi=yes|q1=We're going to make a great Ferret team. Right, Ash?|Olivia|q2=Yeah. Right. I'm in.|Ash|Olivia and Ash regarding their reassignment{{Ref/Reuse|ll c28}}}}
Before the 717th could evacuate, the newly elected [[President of Gao]] [[Arlo Casille]] sent [[Gao Republic]]'s military to forcefully remove the UNSC from the planet. Olivia and Ash joined Fred at the [[Portable Spartan Support Module]] in order to acquire their armor. However, Intrepid Eye had taken control of the module and attempted to suffocate Lopis inside the [[airlock]], but the Spartans were able to free the inspector and neutralize Intrepid Eye's inspection drone. Determined to prevent the Forerunner site from falling into Casille's hands, Blue Team, Lopis, and Roams Alone embarked to destroy the facility with a [[HAVOK tactical nuclear weapon]]. Pursued by [[MV-29 Wyvern]]s carrying [[Gao battle-jumpers]], the team traveled in Warthogs to the [[Well of Echoes]], below which the Forerunner support base was located, and boarded the [[D102 Owl]] [[UNSC Silent Claw|''Silent Claw'']], with [[Serin Osman|Rear Admiral Serin Osman]] waiting on board. Mark dropped the HAVOK into the Well of Echoes, destroying the Forerunner base, while Blue Team exfiltrated from the planet successfully.{{Ref/Reuse|hll}}

With Intrepid Eye captured, the UNSC left Gao. Fearing that Gamma Company's illegal brain mutations may cause a crippling public relations scandal were they to be discovered, Osman had Mark, Ash, and Olivia officially marked as [[killed in action]] during the preceding mission and transferred to a classified [[Ferret]] team of which she gave command of to Lopis.<ref name="ll c28">'''Halo: Last Light''', Chapter 28, ''pages 330-333'' (Google Play edition)</ref>

===ONI career===
In the following months, Olivia, Ash, Mark, and Veta Lopis underwent a training regimen to become ONI field operatives, with Olivia assigned as the Ferret Team's information specialist. To prepare her for her specialization, Olivia underwent an ONI Digital Infiltration and Sabotage course, which she was halfway through by mid-September 2553. While she and the other Gammas were exceptionally quick to learn the new skills, their military background meant they would often instinctually fall back to lethal force in life-or-death situations. During this time, they regularly moved from one planet to another; the colonies they visited included [[Jastolo]].<ref name="ant">'''Halo: Fractures''', "A Necessary Truth"</ref>

====Neos Atlantis====
{{Quote|no=three|q1=I'm gonna crush that fat fart's tiny little... ears.|Olivia|q2=His ears, huh? Really?|Lopis|q3=Okay, not really. But whatever I crush, it's going to hurt him. A lot.|Olivia|Olivia-G291 after being drugged by Spencer Hume{{Ref/Reuse|ant}}}}
On [[2553#October|October 14, 2553]], the Ferret Team participated in a training exercise against [[Oscar Squad]] at [[UNSC Recreational Facility 6055-NA-A]] on [[Neos Atlantis]]. Olivia was responsible for hacking into the facility's booking system to reserve the hotel's prestigious Halsey Suite for the team to use as a safe house for the duration of the mission. When the team went undercover, Olivia adopted the cover identity of "Lieutenant Bati", a [[Luna OCS Academy]] graduate, wearing makeup applied to make her appear older than her actual age. At the facility's [[officers' club]], she was approached by a dubious-looking man appearing to show interest in her—in fact the reporter [[Spencer Hume]], who gave her a glass of [[zantelle]] laced with [[nicothiotal]] in an attempt to coax her into revealing classified information about the Spartans and Gamma Company in particular. Realizing Olivia had been drugged, Lopis ordered the rest of the team into action. After Mark seized Hume, Lopis escorted Olivia into the Halsey Suite and administered a counteragent to the nicothiotal.{{Ref/Reuse|ant}}

As Olivia recovered, Mark and Ash returned to the Halsey Suite, with Mark having been attacked on the way by the waitress who had served Olivia's drink earlier. Not long after, they were joined by Rear Admiral Osman, accompanied by Oscar Squad's [[Svenson|Commander Svenson]], who claimed to have witnessed Mark and Ash carrying a body and demanded an explanation. After a brief argument between Lopis, Svenson and Osman, the admiral left the suite, giving the Ferret Team two hours to resolve the situation. Ash and Mark explained what had happened—Mark had accidentally killed Hume when he was attacked and the two had disposed of the body afterward. After Hume's identity was discovered, Olivia used ONI's [[Facial Recognition Database]] to identify Mark's assailant as a former ONI commander named [[Ota Gallo]], now working for the private security company [[Dark Moon Enterprises]]. Olivia subsequently used Hume's [[COM pad]] to send a message to Gallo in order to lure her into the suite, with a copy of the message sent to Osman. Gallo and two of her henchmen stormed the Halsey Suite immediately afterward, although the Ferrets managed to defeat the attackers after a brief firefight. Though Olivia received multiple injuries, she was able to neutralize Gallo with a thrown knife, causing the rogue operative to be blown apart by her own [[grenade]].{{Ref/Reuse|ant}}

The Ferret Team's attempt to evacuate in the aftermath of the attack was cut short by Admiral Osman returning to the suite with an [[ONI Security|armed escort]]. Commending Olivia for her actions, the admiral claimed Hume's personal effects and asked Lopis what had really happened to Hume. Lopis lied that Gallo killed Hume after the reporter was planning to name her as his source. While clearly incredulous, Osman was apparently satisfied with the explanation.{{Ref/Reuse|ant}}

====Assassination of Admiral Tuwa====
{{Main|Operation: RETRIBUTION}}
During the final stages of the Ferret team's training in early December 2553, UNSC Admiral [[Graselyn Tuwa]] was assassinated and her family abducted during an attack on the {{UNSCShip|Donoma}}. The Office of Naval Intelligence resolved to respond to the crisis with a swift retaliation, though not before they could identify the perpetrator and rescue the hostages. Lopis' Ferret team were summoned to an ongoing investigation of the carnage on the ''Donoma'' on December 8. Due to the nature of the attack, the [[Keepers of the One Freedom]] were identified as the main suspects, and [[Serin Osman|Admiral Osman]] assigned the case to the Ferret team as their first actual mission. In the following days, Olivia and the rest of the team were deployed undercover on [[Venezia]] to infiltrate the local underworld and attract the attention of the Keepers of the One Freedom, posing as a gunrunning crew interested in selling a collection of [[HAVOK tactical nuclear weapon]]s that they had stolen from the {{UNSC|Taulanti}}.

During the team's time on [[Salvation Base]], Olivia worked to hack a [[Dark Moon Enterprises]] [[Turaco]] and interacted with the [[smart AI]] [[Argie]], in reality a remote aspect of [[Intrepid Eye]], the true mastermind behind the plot. Argie ultimately erased herself and the Turaco's nav logs to keep Olivia from learning anything from them, but the Ferrets and [[Blue Team]] were able to escape in the craft as the HAVOKs destroyed Salvation Base. Using the forensic evidence recovered from the bodies of the admiral's family, which pointed to their kidnapping being due to their immunity to [[asteroidea merozoite]], Olivia helped Veta to pinpoint the rough location on [[Gao]] where the murders had taken place. The investigation led the teams to [[Pinnacle Station]] and [[Meridian]] where they came up against the rogue ONI unit [[Papa-10]]. At the end of the mission, all members of the conspiracy were apparently and the cryo-jars containing the Tuwas' internal organs destroyed.

After the mission, Admiral Osman sent the Ferrets back to the [[Mill]] to complete their training. She would privately admit to Veta that something big was coming and she needed the team to be prepared for it.<ref>'''[[Halo: Retribution]]'''</ref>

==Personality and traits==
Olivia is energetic and clever and has shown to be quick to catch on to new ideas.{{Ref/Reuse|ll c28}}<ref>'''Halo: Fractures''', "A Necessary Truth", page 234'' (Google Play edition)</ref> She is also empathetic and perceptive, for example quickly noticing [[Veta Lopis]]' anxiety in tight spaces and attempting to calm the inspector down. This was ostensibly to avoid the pair from being discovered, though she also appeared to show genuine concern for Lopis' well-being, unexpectedly opening up to her about a fear of her own; namely one of "white fire" generated by a [[plasma]] discharge. Psychologists stated this was because she had seen her family die in a plasma strike, though she could no longer remember the details of the event herself. As was the norm with Spartan-IIIs, Olivia joined the program in order to avenge her family and homeworld. As she was trained, however, she would come to be motivated by a desire to prevent anyone else having to suffer a similar fate. Olivia would later reflect on the tragedy not with bitterness but as something that gave her purpose.<ref name="ll13">'''Halo: Last Light''', Chapter 13, ''pages 173-177'' (Google Play edition)</ref> She even appeared to take some measure of pride in the Gammas' augmentation-induced mental condition, namely their ability to fight under pain intolerable to any other human.<ref>'''Halo: Last Light''', Chapter 23, ''pages 294-295'' (Google Play edition)</ref>

While cordial around her peers, Olivia shows considerable hostility to those she distrusts. Being highly loyal to her team, she quickly noticed Veta Lopis' attempts to gauge information about [[Mark-G313]] and grew more upset with the inspector for treating her teammate as a suspect.{{Ref/Reuse|ll13}} However, while she seemed to lose her trust in Lopis after the encounter with [[Petora Zoyas]], Olivia did not hold a grudge with the inspector for long, having already grown to respect her after the battle in Wendosa and later responding to the creation of the Ferret Team with enthusiasm.{{Ref/Reuse|ll c28}}

Olivia is known as the stealthiest Spartan in Gamma Company and is consequently called "O" for short because she is "as whisper-quiet as her vowel namesake.{{Ref/Reuse|goo116}} [[Kurt Ambrose]] believed that Olivia could have been wearing fluorescent orange fatigues and still blend in with the terrain.<ref>'''Halo: Ghosts of Onyx''', ''pages 252-253''</ref> Following her assignment to the Ferret Team, she specialized in electronic intelligence and hacking.{{Ref/Reuse|ant}} Olivia is capable of interpreting most of the Sangheili alphabet.<ref>'''Halo: Retribution''', "Chapter 6''</ref>

==Physical description==
Olivia is of East [[Africa]]n descent; [[Catherine Halsey|Dr. Catherine Halsey]] estimated that her origins were in the [[Wikipedia:Horn of Africa|Horn of Africa]].<ref>'''Halo: Glasslands''', ''page 37''</ref> In 2553, Veta Lopis remarked that she looked notably young, "barely even a teen", at the age of fourteen.{{Ref/Reuse|hll}}
