Kelly-087

Were you looking for the ODST named Kelly?

"Kelly's the fastest Spartan."

- Kurt Ambrose

Petty Officer, First Class Kelly-087, born Kelly Shaddock, is a SPARTAN-II supersoldier of the UNSC Naval Special Warfare Command. She is renowned for her incredible speed, even without her MJOLNIR armor. As of 2558, she is one of the few active Spartan-IIs. She had participated in 201 operations—124 of which were full campaigns—as of August 2558, more than any other Spartan with the exception of John-117. Her most prominent assignment is with Blue Team, in which she continues to serve as a general combat operator as of 2558.

Early childhood
Kelly Shaddock was born on the Inner Colony world of Imber on September 21, 2510. She was conscripted into the SPARTAN-II program at age six in 2517 when she was singled out as a physically and intellectually superior child by Doctor Catherine Halsey. During her abduction she eluded Retrieval team Gamma for six hours but eventually came forward when she thought the abduction was a game for her birthday. Her near-escape resulted in the implementation of new retrieval protocols to avoid further mistakes. After her abduction she was replaced with a flash clone. She was then sent to the FLEETCOM Military Complex at Reach to begin her training.

SPARTAN-II training
"I'm fast. Real fast."

- Kelly to John-117 and Sam-034

Under the guidance of Chief Petty Officer Franklin Mendez and Déjà, the Spartans began their SPARTAN-II training. On her first day of training, Kelly was teamed up with John-117 and Samuel-034 during a drill at Military Reservation 01478-B. Their team did poorly, because of the lack of teamwork, and finished in last place. They were not allowed to eat that night. The next day Kelly showed her true speed by running for a pulley lift, which she reached twice as quickly as John and Sam. They did not come first, but they did come in third. This was just the first of many times that her speed would be a key factor in strategies. The exercise led to the formation of a camaraderie between the three Spartan trainees and they became good friends. When the Spartans' heads were being shaved for the first time, Kelly disarmed the Master Sergeant barber of his clippers, requiring three aides to force her down and shave her head.

Kelly later trained with her fellow Spartans at the Military Wilderness Training Preserve, with each Spartan being dropped off at a different point in the preserve. The Spartans regrouped and made their way to the extraction point. There, they were almost forced to kill a squad of UNSC Marines. However, Kelly worked together with John, Sam, Fhajad-084, and Linda-058 to defeat the Marines—using her speed to distract the Marines. All the Spartans managed to reach the Marines' D96-TCE Albatross and then they commandeered the dropship to leave the preserve. Kelly participated in numerous training missions with the Spartans from 2517 to 2525, including those in Emerald Cove, Chiron Test Station, and the Military Wilderness Training Preserve in the Highland Mountains. By July 14, 2523, Kelly and the Spartans had begun facing the formidable Tango Company in simulated war games.

After her Spartan augmentation procedures at an ONI medical facility, Kelly was close to death. She was the slowest to recover from the operations, and many of her fellow Spartans were afraid that she would not make it. She did, and her already amazing speed was even further augmented. John-117 noted that she was "...almost untouchable, no one could touch her if she didn't want them to."

Early career
"Flawless amplification of speed and power. It’s like I’ve been training in this suit for years."

- Kelly, commenting on the MJOLNIR Mk. IV armor

Kelly participated in Operation: TALON, the Spartans' first mission to Eridanus Secundus in the Eridanus system. She, along with John, Fred-104, Sam and Linda, boarded the Laden and infiltrated the rebel asteroid base. They then captured Colonel Robert Watts, a leader of the United Rebel Front. After the First Battle of Harvest, Kelly later attended the UNSC briefing by Admiral Michael Stanforth and the AI Beowulf about the emerging Covenant threat. The training of Kelly, and the rest of the SPARTAN-IIs, was accelerated and the Spartans were sent to Chi Ceti IV to receive their new MJOLNIR Powered Assault Armor from Damascus Testing Facility to aid them in combat against the Covenant. While in orbit over the planet, a Covenant ship appeared in the system and attacked the frigate the Spartans were aboard,. The Spartans were eventually able to retrieve the MJOLNIR armor and then left to return to the Commonwealth in a Pelican. However, Unrelenting returned to the battle and began to engage the Commonwealth, severely damaging it. Taking the Pelican's ANVIL-II AS missiles, all the Spartans used thruster packs to direct themselves into a hull breach in Unrelenting, however only Kelly, Sam, and John made it inside. Inside the ship, they engaged Kig-Yar soldiers, one of which created a breach in Sam's armor. Unable to return to the vacuum of space, Kelly and John reluctantly left Sam behind so he could detonate the missiles and destroy the ship. After the battle, Kelly was assigned to Blue Team.

In 2526, the Spartans were deployed to Circinius IV to combat a Covenant invasion. During the battle, they received a distress signal from a cadet squad pinned down at Corbulo Academy of Military Science. Kelly was given command of Blue Team while John went to rescue the cadets. John later radioed Kelly, telling her to inform Command that he had four survivors. He then told her to take her team north for Pelican extraction and that he would rendezvous soon. Soon after, Kelly met with John and the three surviving cadets at the extraction point and they successfully evacuated on the Pelican. During the flight, Kelly and Fred removed their helmets. When Cadet Sullivan asked how old they were, Kelly and Fred exchanged glances and responded simply, "That's classified."

By 2531, Blue Team had repeatedly disrupted the operations of the United Rebel Front, including at Station Jefferson, onboard the destroyer Origami, in Micronesia, and at a high-explosives manufacturing facility at an unspecified location. On May 1, 2531, Blue Team, then consisting of Kelly, Linda, Fred, John, and Kurt-051, had infiltrated a URF military base on Victoria, Camp New Hope. However, the Insurrectionists successfully ambushed Kelly, Linda, Fred, and John using an antigravity plate which disabled the Spartans. Before the rebels could interrogate the Spartans, Kurt freed Blue Team using a M12 Warthog and Asteroidea anti-personnel mines. However, the rescue resulted in the death of the high-ranking rebel leader General Howard Graves.

Late war
"Kelly-087"

- John-117

In 2535, Kelly was present at the Battle of Jericho VII. She was designated as Blue-Two on John's Blue Team during a mission to distract the Covenant while Red Team would plant a HAVOK tactical nuclear weapon to destroy a Covenant landing zone. However, after three days of hard fighting, they were forced to retreat as the planet was glassed.

In Operation: PALE SHADOW on Eirene, Kelly triggered a reactor breach that led to a 50 megaton blast towards a Covenant forward operating base, single-handedly saving the city of New Kona. Later, in 2544, Kelly also participated in an ONI-led operation, codenamed Operation: WARM BLANKET, which required a team of Spartans (consisting of Solomon-069, Arthur-079, Frederic-104, John-117 and herself) to assault a Covenant fleet using Booster Frames to recover Dr. Catherine Halsey. The Covenant fleet was temporarily unable to enable their slipspace drive due to a stellar magnetic field, providing the Spartans some time to retrieve the package before the Covenant fleet departed. During the course of the operation, Arthur-079 and Solomon-069 were killed by the Covenant. The surviving Spartans then infiltrated the Covenant flagship and got separated as they made their way to Halsey. The operation was successful with the Spartans escorting her back to the ONI stealth ship that deployed them.

In Operation: DEVIL FREEDOM, she assisted the evacuation of civilians and targeting of Covenant landing craft for orbital bombardment on Imber. In Operation: HEMORRHAGE, Kelly was secretly sent into a Covenant fleet to infiltrate an important capital ship—Doctrine's Command. Upon entering the ship, she set it on a collision course for other ships in the fleet, and destroyed half of the fleet in the process. In 2552, Kelly was sent to Sigma Octanus IV as part of Operation: OCEAN BREAKER. She was designated as Blue-Two, part of John's team, and carried a HAVOK tactical nuclear weapon to the Covenant-held city of Côte d'Azur. Successful, her team boarded a Pelican, docked with the and returned to Reach.

Reach
She was briefly aboard the in preparation for Operation: RED FLAG; the Spartans' mission to capture a Covenant Prophet. Unfortunately, as the Autumn was preparing to leave, they were recalled to defend Reach as a massive Covenant fleet entered the system. Designated as Red-Two, Kelly was assigned to Fred's team, with the mission to defend the generators for the orbital MAC guns. As their Pelican, Bravo 001, descended to the surface of Reach, it was shot down by Seraphs. The Spartans were then forced to jump from the crashing Pelican, which led to several Spartans being killed and more injured on impact. Kelly was apparently injured in this fall though she made no indication of it.

They eventually rallied at ODG Facility A-331. After receiving a message from Vice Admiral Danforth Whitcomb, Fred assigned Kelly to Team Alpha, along with himself and Joshua-029. They piloted Banshee fliers to a Covenant landing zone where she threw a Fury tactical nuclear weapon into the gravity lift of a Covenant cruiser. Though they successfully destroyed the landing zone, Joshua was shot down and later marked as MIA.

She and Fred were then forced to retreat back to Team Delta's position after it appeared that all the Spartans of Team Beta were killed at the ODG Facility. They were then forced to land, contend with a pair of Hunters, and commandeer Wraith tanks in order to get to CASTLE Base where Team Delta was hidden. They met up with Vinh-030, Isaac-039, and William-043. The five Spartans were unable to enter the facility until Kelly thought to whisper Oly Oly Oxen Free into the speaker, which opened the door, and it turned out that Dr. Halsey was still in the facility.

Kelly's injuries turned out to be life-threatening; she had a fever and low blood pressure due to moderate bleeding in her liver, and one of her lungs had completely collapsed. Dr. Halsey noted that it was amazing Kelly was still alive, let alone still fighting, despite these two potentially fatal conditions.

The Covenant attacked immediately and Dr. Halsey was forced to activate Operation: WHITE GLOVE. In addition, she gave the Spartans new MJOLNIR parts which were being field-tested, but had not yet been certified. Kelly received an improvement to her neural induction circuits, giving her twitch response time and a speed boost. The Spartans were then trapped beneath the base for several days until Fred came across the entrance to a Forerunner installation. After exploring the vast complex for some time, the five Spartans and Dr. Halsey discovered a Forerunner crystal at the center of a vast chamber.

The crystal sent a spike of radiation that allowed the Covenant to triangulate on the Spartans' position. The Covenant breached the underground complex, and used a gravity lift to send massive amounts of ground forces inside. The group was forced to retreat, but Vinh and Isaac disappeared after their satchel charges exploded. Kelly, Fred, Will and Dr. Halsey were then trapped in a cavern for several days until they were rescued by John-117, Anton-044, and Admiral Whitcomb. During the operation though, Kelly was hit by the assault cannons of two Hunters as she tried to protect Dr. Halsey. Once again, she was critically wounded. With burns on seventy two percent of her body, she required dermacortic steroids to recover.

Kelly was whisked aboard a Spirit and taken to the captured Ascendant Justice/Gettysburg. Some time after she was healed, Halsey sedated her and had Corporal Locklear carry her aboard the Beatrice; a retired stealth ship and the private vessel of the rebel Governor Jacob Jiles, without anyone's knowledge or permission. The Beatrice then entered slipspace, heading for Onyx.

Onyx
"Why are they so...twitchy?"

- Kelly, expressing her skepticism of the Spartan-IIIs' efficiency to Kurt Ambrose.

On November 3, Halsey and Kelly eventually made it to Onyx, where the Beatrice immediately came under attack by Onyx Sentinels. Kelly awoke from her sedation only moments before, and was forced to land the ship safely as Halsey passed out due to extreme acceleration caused by their entry maneuver. On the surface, Kelly and Halsey soon reunited with SCPO Mendez and some of the remaining SPARTAN-II and SPARTAN-III soldiers. Soon after, Kelly, as the fastest Spartan, served as bait for the Onyx Sentinels and with coordinated teamwork, they managed to destroy several of them.

After the arrival of Will-043, Linda-058, and Frederic-104, the humans used a Covenant dropship to enter a vast, excavated Forerunner city within Zone 67, and located Onyx's map room. They then destroyed a massive Sentinel manufacturing facility under orders of AI Endless Summer. After recovering Team Katana, whose members were in slipspace field pods, they teleported to Onyx's core room, soon followed by a Covenant army under the command of Fleet Master Voro Nar 'Mantakree.

The Spartans then held off the Covenant forces at a slipspace portal in the center of the core room. When Kelly killed a group of Elites in close quarters in an attempt to buy them more time, a Hunter pair took her by surprise, and Holly-G003 sacrificed her life to save her, soon followed by Will. Kurt then ordered Kelly, along with Dr. Halsey, Fred, Linda, and the rest of the surviving Spartan-IIIs, to enter the slipspace rift, while he stayed behind and detonated two FENRIS nuclear warheads to stop the massive Covenant army.

Shield world and recovery
"Welcome to Blue, Spartans. We're going to make a great team."

- Kelly welcoming the Spartan-IIIs to Blue Team

Having passed through the slipspace rift, Kelly and the rest of the human survivors found themselves trapped in a massive Dyson sphere contained within a slipspace bubble of compressed space-time, formerly hidden inside the core of Onyx. She and the others then began trying to find a way to revive Team Katana to find a way out of the shield world.

After the survivors had explored the sphere for several days—over three months in normal space-time—they discovered a group of Huragok which helped them establish contact with the ONI ships outside the sphere and eventually bring the sphere back into normal space in February 2553. They were then recovered by the ONI team Kilo-Five and taken to a debriefing in HIGHCOM Facility Bravo-6 aboard the. Kelly, along with the rest of the surviving Spartan-IIs, were present in the Voi Memorial ceremony on March 3, 2553.

At one point after her recovery from the shield world, Kelly was deployed to Installation 03 to provide security for a research facility on the ring as part of Operation: FLINT DEVIL.

Conflict on Gao
In May of 2553, the Office of Naval Intelligence learned of a Forerunner structure host to an ancilla located within the Montero Cave System on the human Outer Colony of Gao in the Cordoba system. Kelly and the rest of Blue Team—Fred, Linda, Tom-B292, Lucy-B091, Ash-G099, Olivia-G291, and Mark-G313—were attached to ONI's 717th Xeno-Materials Exploitation Battalion, a research battalion charged with recovering the AI. Meanwhile, a string of murders had been occurring in the cave systems; the UNSC forces on Gao agreed to help the Ministry of Protection with the murders while they covertly located the AI, both parties unaware that the murders were caused by the ancilla.

After another victim had been discovered in the caves, Kelly led a splinter team consisting of herself, Tom, Lucy, and Linda, tasked with escorting the GMoP team and the bagged victim back to the village of Wendosa, while the rest of Blue Team continued to search for the ancilla. Upon arriving at Wendosa on July 4, 2553, the Spartans attempted to deliver the victim to a Pelican dropship for extraction. However, the four Spartans were spotted by members of the Keepers of the One Freedom, a radical Covenant sect that had traveled to Gao in search for the ancilla. The cult's Jiralhanae leader, Castor, believed that the bagged victim aboard the Pelican was actually the ancilla and ordered his forces to attack Wendosa to retrieve the AI. As the Keepers of the One Freedom attacked the village, Kelly and the other Spartans helped Charlie Company defend the rest of the research battalion. While the company took a defensive position in Hotel Wendosa, Kelly and the Spartans formed a skirmish ring around the hotel, attempting to disrupt enemy formations and prevent a Jiralhanae charge.

Fred, the rest of Blue Team, and Special Inspector Veta Lopis arrived at the village with the captured ancilla to aid the company. Kelly and Linda fired explosives at the Keepers from the Wendosa rooftops. When the Jiralhanae attempted to charge at the village, all Spartans of Blue Team worked together to thin their numbers. During the attack, Fred was ordered to return the captured ancilla to Commander Murtag Nelson at the Montero Vitality Clinic. However, while leaving Wendosa in a Falcon, the aircraft was shot down by Keeper fire. The rest of Blue Team regrouped and, with Lopis, traveled to the Falcon's crash site to locate Fred and the AI. The team was assaulted by the Keepers, but they were eventually able to defeat the charging Jiralhanae with the help of the battalion's Alpha Company. Having recovered Fred and the ancilla, the team returned to the Montero Vitality Clinic. However, recently elected President of Gao Arlo Casille declared war on the UNSC forces on the planet and Gao battle-jumpers and Wyverns were ordered to engage the battalion's remaining forces.

As the rest of the unit began retreating from the planet, the Spartans and Lopis traveled to the Well of Echoes to detonate a HAVOK tactical nuclear weapon inside to destroy the Forerunner installation within the Montero Caves, denying the anti-UNSC president access to the installation. Once they retrieved the ancilla and the nuke, Blue Team and Lopis regrouped in the Montero Jungle and headed for the Well of Echoes. Upon arriving at the Well of Echoes, the team boarded a nearby ONI Owl dropship with Rear Admiral Serin Osman aboard. Mark-G313 dropped the nuke into the Well of Echoes and the Owl left the planet as the HAVOK detonated and destroyed the Forerunner installation.

Other operations
In the years following the war, Kelly, Fred and Linda continued to serve under Naval Special Warfare on numerous highly confidential missions under ONI's direct oversight, deploying to the outer fringes of human-controlled space to eliminate hostile Covenant remnants. One of these missions undertaken by Kelly was codenamed Operation: COUGAR REDEMPTION.

Gamma Halo


On July 26, 2557, Kelly and the rest of Blue Team reunited with John-117 for a mission to investigate the recent loss of contact with a science team and their SPARTAN-II escort, Team Black, on Installation 03. Soon after their arrival Linda found tracks left by a Crawler. Fred and Linda found the bodies of Team Black while John and Kelly found the scientists. Shortly after they left the camp they were attacked by Promethean Knights, but managed to fend them off. They continued following the Crawlers' tracks and came to where the Composer was originally located. Kelly found a tunnel which they followed down, soon finding the Composer's Abyss.

Traveling through a slipspace portal at the end of the Abyss, Kelly and the other Spartans found themselves in a deserted Forerunner city where they came across a plaza housing six Composers. The Didact then appeared behind them and announced that the Spartans had arrived in the Composer's Forge. A firefight broke out and the Didact called forth an army of his newly-created Promethean constructs to combat the Spartans. While Kelly and the Spartans battled the Promethean machines, the Didact took one of the Composers and departed toward the portal, intending to use the device, as well as Gamma Halo, against Earth. Kelly and rest of Blue Team pursued the Didact through the portal and to the top of the Composer's Abyss on Installation 03, where they barely managed to get out of the way of the Composer rising from the pit. The Didact attacked the Spartans, planning to kill Kelly first. However, John sneaked up on the Forerunner and stabbed him in the eye, focusing the Didact's immediate attention on the Master Chief.

The rest of Blue Team recovered and attacked the Didact. Kelly attempted to use a Z-180 Scattershot against the Forerunner, but he simply crushed it in his hands. After a brief fight, the Didact subdued all four Spartans but Static Carillon suddenly appeared behind him and disabled the Didact with his laser and teleported the Didact away before he could finish them off. While John went to pursue the Didact at Gamma Halo's control room, Kelly and the rest of Blue Team returned to the Longsword. After John succeeded in "containing" the Didact, Static Carillon teleported himself and John into Blue Team's Longsword. The monitor subsequently left to repair the ring and Blue Team returned to Earth.

Mission after mission
"The war is over. At least that's what we're told... But those of us in the thick of it... We know better. At the fringes of our civilization, it's raging harder than ever. The violence and suffering continues. And there's noone around to stop it. That's why Blue Team is still active."

- Kelly reflects on the state of conflict in the galaxy.

Returning to Earth, John was debriefed by Hood, where the fleet admiral gave orders for Blue Team to have some rest after years of combat. However, the rest of the team instead left to take on new missions, all of them highly classified. These operations included diplomatic escorts through hostile territory, counter-piracy efforts against salvagers, and strikes against Covenant outposts. At one point in 2558, the team was stationed at the construction site for a new ONI research facility, awaiting orders. Without warning, explosions signaled an attack from fanatical ex-Covenant. During the fighting that followed, the hostiles managed to capture an M510 Mammoth, disable its governor, and drive it down a steep hillside toward the site's main fusion reactor. Blue Team followed in pursuit in an M12 Warthog LRV. With only about a minute left before it impacted the reactor, John, Kelly, and Linda ejected from the Warthog when it was close enough to the Mammoth. The three of them just narrowly managed to wrest control of the hulking vehicle from its Kig-Yar and Sangheili hijackers. Kelly discovered scientists hiding inside the mammoth and relayed this to John, who was driving. Their presence meant he couldn't just drive it off a cliff, as doing so would almost certainly kill them. Instead, he steered it away from the reactor at the last second, but the near miss still resulted in the destruction of a decent amount of fabricated material that had been constructed. Kelly ensured that the scientists onboard were okay. The manager in charge of the construction project rushed over to Kelly and the other Spartans after the smoke cleared and demanded to know who he should blame for the damage. John, who had taken the Mammoth's controls, took responsibility. The incredulous man accused the Master Chief of thinking he could get away with anything because of his status as a hero. At this moment, Fred jumped in to reprimand the thankless individual they had all just saved, finding it difficult to maintain an easy demeanor in the face of such disrespect. John kept a cooler head and directed the team to return to a nearby airstrip, as their mission orders had come in.

At some point, Kelly and the three others returned to the glassed remains of Reach, where they recalled their past and paid their respects to Sam, who had died so many years ago.

Argent Moon
"Shame to lose the Argent Moon, but I'd love to see the look on the Covenant's faces when she goes supernova"

- Kelly-087 about changes in their plan

On October 23, 2558, Kelly and the rest of Blue Team were deployed from the on a mission to find and secure Argent Moon, an ONI research vessel that had been missing for nineteen months. Departing from a Pelican, Blue Team managed to infiltrate the Argent Moon by shooting out one of the windows, subsequently causing many Sangheili part of Jul 'Mdama's Covenant to be sucked out into the vacuum. Ascertaining that there were no human survivors aboard, Kelly and the others fought towards central control, where they planned to disable the gravity and life support systems on the ship in order to kill off the rest of the Covenant.

During the mission, John experienced a vision from Cortana telling him that the Domain was open, that Meridian was next, and that the Reclamation was about to begin. Upon coming to, he told Blue Team what he had seen. Resolving to deal with it later, they continued onwards according to their original plan. Upon witnessing Covenant vessels exiting slipspace all around the Argent Moon, however, the plan changed to asset denial and it was decided that the Argent Moon must be destroyed. Blue Team fought to the ship's reactor and disabled its safeties so that it would begin to overheat and detonate. However, the Argent Moon responded with automatic safeties, moving the reactor to a cooling center where it could be contained. Needing to ensure its overload, Blue Team followed the reactor to the cooling center in vacuum, using Banshees to destroy its coolant pipes. With their interference, the cooling system failed and the reactor began overheating, prepping Argent Moon ' s destruction.

Blue Team needed to escape, but their Banshees would not escape the explosion in time and their arrival Pelican appeared to have been destroyed. John thus ordered them to the hangar where they could take a Winter-class prowler and escape into slipspace. Arriving at a hangar, the Spartans found the parked prowler ONI Acrisius, but needed to recharge its fuel cells. Many more Covenant attacked them while Blue Team defended themselves, waiting for the prowler to prep for launch. With the hangar cleared and the Acrisius ready, John-117 radioed the UNSC Infinity and informed them that he would be sending Blue Team to Meridian. However, Infinity was mysteriously already aware of Cortana's return and ordered Blue Team back to them while another Spartan team was sent to deal with her. Rejecting their orders, Blue Team chose to go AWOL and evacuated aboard the Acrisius, leaving the Argent Moon as it exploded.

Absent without leave
The very next day, the UNSC declared Kelly-087 and the other members of Blue Team AWOL. Fireteam Osiris, a Spartan-IV unit led by Spartan Jameson Locke, was tasked with recovering Blue Team and the Acrisius. Upon arriving at Meridian, Blue Team landed at Apogee Station and proceeded make their way downwards to where the dormant Guardian lay buried. Their arrival on-planet was witnessed by multiple colonists, who were wholly unaware of their intentions. Also unbeknownst to the people of Meridian was the fact that their own Governor Sloan purposefully ensured nobody tried to stop them, as he was already serving Cortana at that point. Blue Team encountered no resistance from the Warden Eternal or any mechanical Prometheans. Fireteam Osiris caught up to Blue Team as they were entering the Guardian. Kelly, Fred, and Linda proceeded to enter the Guardian while John lingered and had an altercation with Locke. Once John had dealt with him and resumed boarding, the Guardian began to awaken. Fireteam Osiris scrambled to escape the collapsing chamber it had been held in as it rose out of the ground. The Guardian caused massive amounts of destruction as it took to the air, both from the very fact that it was emerging from beneath the earth and from electromagnetic shockwaves it sent out continually. During this time, many mechanical Promethean forces were deployed from the Guardian to engage Fireteam Osiris as they tried to escape the destruction in their Pelican. The Guardian jumped to slipspace on a course for Genesis, taking Blue Team with it.

Genesis
"Kelly-087"

- John-117

Upon landing on Genesis, Blue Team came across a series of computer consoles sounding musical tunes of Oly Oly Oxen Free. Following the path unlocked by interacting with those consoles, Blue Team battled through stranded Covenant forces before meeting the Warden Eternal. Shortly after learning of the Warden Eternal's role as Cortana's defender, John demanded to meet her, only for the Warden Eternal to refuse and commence hostilities. Shortly after Blue Team's defeat of the Warden Eternal in battle, Cortana finally revealed herself to them, expressing relief that they made it to Genesis. Upon questioning Cortana on the circumstances of her survival, they learned that the Domain had saved her; Cortana referred to it as the "fountain of youth" for AIs. Suspicious of Cortana's desire to reunite with them, Blue Team proceeded further into the planet in order to physically locate her. Shortly afterward, Fireteam Osiris caught up with Blue Team. Before the two Spartan teams could team up, Cortana separated them. Blue Team fought an uphill battle through Promethean forces and multiple bodies of the Warden Eternal before physically meeting Cortana. There she revealed to them her plan to use the Guardians as a means of enforcing a forced peace upon the galaxy. Rejecting Cortana's plan, John ordered her to stand down and return to Earth with the team. Cortana refused and sealed Blue Team in a Cryptum, intending to keep them in stasis for 10,000 years.

With the aid of Exuberant Witness, Fireteam Osiris narrowly managed to free Blue Team from the Cryptum.

Personality and traits
Fast not only physically but mentally as well, Kelly is highly perceptive and observant. She has a dry sense of humor and often cracks jokes over her and her team's situation and mission. She is less proficient at concealing her emotions than most of her comrades; as such her body language tends to belie her mood. Early in her SPARTAN-II training, she resisted initial indoctrination generally out of fear and anger.

Only a handful of other Spartans have as much experience as Kelly, meriting her a plethora of awards. She claims to be ignorant of these honors she is entitled to and has shown little interest in the biographies and records of non-Spartans.

Skills and abilities
Kelly is the fastest of the Spartan-IIs, making her easily the fastest human to have ever lived. She is capable of running for extended periods of up to 62 kph (38.502 mph) and has quicker reflexes than her peers; within current Mjolnir GEN2 systems, she is capable of running at speeds in excess of 65 kph (40.393 mph). In order to keep her reflexes sharp she exercises routinely with "twitch-response drills" and Zen "no-thought" practices. She has to slow herself down considerably to spar with another Spartan. Her speed has led her to being termed the team's "Rabbit", acting as quick bait to draw enemies into traps laid by the other Spartans. She has also demonstrated an incredible tolerance for pain, as she has been injured quite gravely on several occasions and managed to recover fully each time.

Physical description
At age six, Kelly had her hair dyed blue and was taller than John-117. John eventually outgrew her and her hair color returned to its natural brown color. She originally wore her hair close-cropped, though by 2557 it had grown almost to her shoulders and was worn in a ponytail. John once noted that Kelly's face had a "rough, angular beauty".

Equipment
Kelly-087 prefers armor with full-shield masks in combat. As such, she favored the MJOLNIR Powered Assault Armor Mark IV to Mark VI models of the EVA and Pilot armor variants. Kelly's initial Mark IV armor was base green, with a rabbit painted onto it as a reference to her speed and nickname. The Mark IV EVA armor she later donned was colored white. Kelly began wearing the Hermes armor variant, patterned after EVA armor, once Blue Team transitioned to the Mjolnir GEN2 platform. Her Spartan tag, 087, is written in Braille on the left side of her chest armor.

Due to her speed and ability to quickly eliminate any distance between herself and opponents, she prefers to arm herself with close-range weaponry such as the M90 shotgun. However, she has also frequently wielded various models of assault rifle, typically of the MA5 series. During the Spartans' escape from CASTLE base, she armed herself with dual M6D pistols. Kelly prefers to use human weaponry, comparing using Covenant weapons to be barely better than throwing rocks. She has also used Promethean weapons on occasion, beginning with her deployment to Installation 03, though her preferred weapon loadout as of 2558 remains her personal M45 shotgun, Oathsworn, and an M6H2 magnum sidearm.
