See the Character/HaloSpartanIVProgram page for more details.

* NotSoStoic: [[spoiler:She's freaked out when the Covenant invade Corbulo Academy.]]

* OhCrap: When the video he hacked suddenly shuts down as he is showing it to Lasky, Sully panics and thinks that ONI managed to it trace it back to him, causing him to run off to ask Dimah to speak with her mother on his behalf. [[spoiler:However, the computer likely shut down due to the Covenant attacking the planet.]]

** JerkassHasAPoint: Maya is forced to admit the validity of his point that releasing all the intel could possibly do more harm than good, though she still thinks he's an asshole.

* SacrificialLion: [[spoiler:The first member of Hastati to die.]]
* ScrewTheRulesIHaveConnections: [[spoiler:She intimidates a Marine into letting her onto one of the first evacuation pods by threatening him with her mother’s authority as Secretary of [=FLEETCOM=]. She offers the same chance to her squadmates, but they all refuse, and she dies when the Covenant destroy the orbital elevator.]]

* [[ByTheBookCop By-The-Book Soldier]]

* BenevolentAI: Despite being both damaged and technically non-sapient, it goes out of its way to help the Rookie when he's on his own New Mombasa. And that's not even counting its loyalty to Sadie.

[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/b6e6d7510cc6478b420555a434261225.jpg]]
->'''Creation date: May 9, 2541'''
->'''Voiced in English by: Carole Ruggier'''
->'''Voiced in Latin American Spanish by: Veronica Lopez Treviño (Mexico)'''

A "Dumb" AI assigned to assist NOBLE Team, she provided intelligence support to them during the Fall of Reach.

* ExpositionFairy: In ''VideoGame/HaloReach''.
* MissionControl: For NOBLE Team during the Fall of Reach.
* NotSoStoic: When [[spoiler:Carter does not answer her after being critically wounded near the end of the game]], she notes that he is scaring her.
* TheStoic: As a "Dumb" AI, Auntie Dot does not have as much of a personality as Cortana or Serina, and simply provides NOBLE Team with information without any additional comments.
* VoiceWithAnInternetConnection: In fact, she seems to [[TheVoice completely lack a holographic avatar]], unlike most [=AIs=].
* WhatHappenedToTheMouse: Her fate is never made clear in ''VideoGame/HaloReach'', since she is not actually in the armor of any of the Spartans and is at an unknown location on the planet. Even the planet being [[DeathFromAbove glassed]] is no guarantee of her death if she was still on Reach, since there have been [=AIs=] who survived glassings thanks to their storage facilities being located underground.

[[folder: Isabel]]
!!'''Isabel (ISA 1307-2)'''
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/isabel_0.png]]
->'''Creation date: March 2556'''

An AI serving at the Henry Lamb Research Outpost on the Ark, Isabel was the only survivor when the Banished attacked the facility and massacred the research team. Distraught and terrified, she sent out a distress call which was answered by the crew of the ''Spirit of Fire'', leading to her rescue by Red Team.

* CowardlyLion: Is absolutely terrified of Atriox and the Banished, yet unhesitatingly does her best to help the ''Spirit''[='s=] crew fight them.
* LikeADuckTakesToWater: She's a civilian AI, but grows pretty quickly into her new role as a military AI. It helps that she already specialized in logistics.
* ItsPersonal: Atriox slaughtered her friends.
* MissionControl: After being taken in by the ''Spirit of Fire'', one of her main roles becomes being mission support for the guys on the ground.
* MrExposition: Serves as this in-universe, bringing Cutter and his crew up to speed on what happened while they've been adrift.
* SoleSurvivor: The only one of the UNSC's research teams on the Ark to survive the Banished attack.
* SurvivorGuilt: Isabel clearly feels very distraught at having seen the Banished slaughter the researchers she considered her friends.

[[folder: Wellsley]]
!!'''Wellsley'''
->'''Creation date: Unknown'''

The other AI stationed aboard the ''Pillar of Autumn''. His avatar is an 18th-century British Army officer.

* LikeADuckToWater: She's a civilian AI, but grows pretty quickly into her new role as a military AI. It helps that she already specialized in logistics.

* FearIsTheAppropriateResponse: Her initial advice to Red Team and then Cutter boils down to 'run the hell away from Atriox'.

* YouHaveGotToBeKiddingMe: Pretty much her reaction to Red Team asking what the strength of the ''Covenant'' force that attacked her outpost was.

-->'''Creation date: Unknown'''

* TheAtoner:His brain donor, Graham Alban, was a researcher for the SPARTAN-II program who committed suicide out of guilt for his role in the project, but not before he requested that his brain be used for a AI designed to support Spartans; this explains both BB's absolute hatred for Halsey, and his relative sympathy for Osman, as well as Naomi and her Insurrectionist father.

->'''Creation date: August 17, 2552'''
->'''Voiced by: Peter Serafinowicz'''

Often called "BB" for short, Black-Box is a Smart AI who was initially assigned to ONI unit Kilo-Five after the end of the war against the Covenant, and is the current assistant to the head of ONI herself. His avatar is a [[ExactlyWhatItSaysOnTheTin Black Box]].

* AndroidsArePeopleToo: He doesn't care for being "human", but he does hope that his kind will one day stand alongside their creators as at least equals.
* TheAtoner:His brain donor, Graham Alban, was a researcher for the SPARTAN-II program who committed suicide out of guilt for his role in the project, but not before he requested that his brain be used for a AI designed to support Spartans; this explains both BB's absolute hatred for Halsey, and his relative sympathy for Osman, as well as Naomi and her Insurrectionist father.
* BerserkButton: Though he generally accepts ONI's moral shadiness (and is indeed on quite friendly terms with both Parangosky and [[spoiler:Osman]]), he strongly ''hates'' Dr. Halsey for her role in the Spartan-II program. [[spoiler:This is later explained by the reveal that his brain donor committed suicide out of guilt for his own role in the project.]]
* CallAHumanAMeatbag: Indeed, the reason why his avatar is a box instead of a human is because he doesn't want to represent himself as something he considers to be intellectually inferior.
* TheCracker: Very much so to his enemies, even those within ONI.
* DeadpanSnarker: Not even his ONI superiors or the rationale behind Kilo-Five's own mission escape his scorn.
* [[DefrostingIceQueen Defrosting Ice King]]: Becomes something resembling a friend to the rest of Kilo-Five as time goes on, despite his wariness about getting too close to humans.
* InsufferableGenius: Described as being deeply narcissistic, and he certainly doesn't hide it.
* JerkWithAHeartOfGold: Does care for the rest of Kilo-Five in his own way, and expresses sympathy towards the parents of the kidnapped Spartan-II candidates.
** Despite taking part in [[spoiler:Iona's sham trial]], he's quite sympathetic towards both her and her cause, and does his best to keep her [[LetThemDieHappy feeling hopeful]] [[spoiler:even as she's being put into stasis]].
* LaserGuidedAmnesia: [[spoiler:Deliberately erases part of his own memory so that ONI will believe that Naomi's father died when the ''Pious Inquisitor'' self-destructed.]]
* MissionControl: For Kilo-Five. Years later, he's assigned to be this for Maya Sankar.
* MoralityPet: [[spoiler:Is revealed to be one for Parangosky, who was good friends with his original brain donor.]]
* SelfDuplication: Can split off "dumb" fragments of himself that can operate independently.
* ServileSnarker: Something of this to both Parangosky and Osman.
* VoiceWithAnInternetConnection: For Kilo-Five.
* WellIntentionedExtremist: Like much of ONI, he expresses little regret for doing what he considers necessary if morally unpleasant tasks.

* DeadpanSnarker: Frequently makes snarky comments towards Silva.

%%* QuintessentialBritishGentleman

* WhatTheHellHero: He sides with [=McKay=] in attempting to convince Silva to not bring live samples of the Flood back to Earth, condemning the colonel when he refuses to listen to reason.
-->'''Wellsley:''' Then God help you, because if your plan fails, no one else will have the power to do so.

[[folder: Mack]]
!!'''Mack / Loki'''
->'''Creation date: Unknown'''

The Smart AI in charge of maintaining the colony of Harvest's agricultural systems, as well as assisting the citizens of the planet. He is very flirtatious towards and fond of Sif, the AI in charge of Harvest's shipping operations. He can also be turned into Loki, a former warship AI placed by ONI to defend and monitor the colony. His chosen avatar was that of an American cowboy, reminiscent of those from 20th-century western movies.

[[folder: Rebecca]]
!!'''Rebecca'''
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/7f17090aaf0bda27f07383a64b34a976.png]]
->'''Creation date: Unknown'''

-->''"We're at war, Commander. Reach has fallen. Our backs are against the wall. Extreme measures are necessary to ensure our survival."''

An ONI Smart AI assigned to the UNSC ''Red Horse'' to ensure ONI's experiments on the prison ship ''Mona Lisa'' are covered up. She has two avatars: one of a middle-aged Italian woman in a flower dress, and another described as a cross between Athena and Ares.

* AIIsACrapshoot: Foucault notes that she is over six years old, and displays some signs of rampancy. She is not happy when he points this out this fact and that he will order her mental state investigated.
* BitchInSheepsClothing: Uses her middle-aged form to make people around her feel more relaxed. In part to prevent this, Commander Foucault often insists that she stays in her warrior form when speaking to him.
* {{Jerkass}}: The entire crew of ''Red Horse'' pretty much despises her due to her secretive and uncaring nature.
* ReplacementScrappy: InUniverse: The ''Red Horse'''s previous AI Chauncey was suddenly replaced by Rebecca before the mission. He was well-liked and open with the crew, while Rebecca is cold, secretive, and extremely disliked.
* TheSpook: An AI version of one anyway.

[[folder: Mo Ye]]
!!'''Mo Ye'''
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/e3f370f2446483acd9501ead115ae5db.png]]

->'''Voiced by: Creator/MonaMarshall'''

A Smart AI aboard the UNSC ''Heart of Midlothian''. She is represented as a middle aged Asian woman.

* AIIsACrapshoot: Averted, the Covenant use an Engineer to damage her systems, locking her out of the system. This greatly diminishes her capacity, but she remains rational.
* IWasJustJoking: [[spoiler:She tells the Covenant that the Self Destruct will take four minutes. Then, as they start to run, she informs them she was only kidding... "There's no need for a countdown whatsoever." She promptly detonates the ship right then and there.]].
* MeaningfulName: Mo Ye was the wife of legendary Chinese blacksmith Gan Jiang, whose blast furnace did not have sufficient ''qi'' to forge a pair of swords for the king within the given three-month deadline. In some accounts of the story, [[spoiler:Mo Ye threw herself onto the furnace to allow the ''qi'' to reach sufficient levels to make the swords]]; in a similar way, [[spoiler:Mo Ye the AI threw herself onto the fire that would kill all of the Sangheili boarding her ship.]]
** ThemeNaming: As the resulting swords would be named for the couple, Mo Ye is also named for a mythological sword, continuing the trend that Cortana and [[VideoGame/{{Marathon}} Durandal]] have between them.
* TakingYouWithMe: [[spoiler:After Baird is killed, she self-destructs the ship immediately, killing the Covenant aboard.]]
* ThreeLawsCompliant: Not by choice. She normally would be able to ignore the laws, but thanks to Covenant meddling she lacks capacity to do so. The laws exist as a kind of backup lockdown feature to limit the damage she could do if her systems were compromised.

[[folder: Iona]]
!!'''Iona (IOA 7201-4)'''
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/iona.jpg]]

!!Army Troopers

[[folder: In General]]
!!'''UNSC Army'''

The branch of the UNSC military primarily responsible for groundside planetary defense.
----
* AllTheOtherReindeer: In ''Literature/HaloGlasslands'', it's noted that for some unknown reason, no Army officers were even invited to attend the ceremony for John-117.
* BadassArmy: They may not usually fight the baddies from planet to planet like the Marines, but several Army units have nevertheless distinguished themselves in combat.
* BadassNormal: Even 1-v-1, a properly-equipped trooper in-game can sometimes take out a superior foe.
* HufflepuffHouse: The second least seen branch of the UNSC armed forces (next to the Air Force), taking ''five'' games to finally show up in a campaign. Supplementary ''VideoGame/{{Halo 4}}'' materials and ''Spartan Ops'' mention that they're also serving alongside the ''Infinity'' on Requiem, but we never actually see them in that game.
* RedShirtArmy: In most of ''VideoGame/HaloReach''.
* WeWillWearArmorInTheFuture: Reasonably effective against bullets and shrapnel, less so against plasma.

* VoiceWithAnInternetConnection

* JumpingOffTheSlipperySlope: TheReveal of ''VideoGame/Halo5Guardians'' pulls this with Cortana, who in the [[VideoGame/{{Halo 4}} previous game]] remained the Chief's friend even as her digital body collapsed and she struggled to remain sane, eventually doing a HeroicSacrifice with the last of her strength. In the following game, she turns out to be alive and supposedly repaired, but now she's at best WellIntentionedExtremist who's going to take over the galaxy with her army of enormous Guardian machines. While she keeps insisting that she has good reasons for doing so, it's clearly bordering on WouldBeRudeToSayGenocide, especially when she imprisons Chief and Blue Team in a Cryptum so they won't interfere with her schemes.
* KickTheDog: Near the end of ''VideoGame/Halo5Guardians'', she taunts each member of Fireteam Osiris about their pasts and declares them to be inferior compared to the [[SuperPrototype Spartan-[=IIs=].]]

* LoveMakesYouEvil: She becomes a ClingyJealousGirl towards John in ''Halo 5''

** ''Halo 4'' towards the end as well, [[spoiler:due to her HeroicSacrifice.]]

* ShutUpHannibal: Gets this a lot from Fireteam Osiris. Even Chief seems to be pissed off at what she's done so far.

* TookALevelInJerkass: While she was originally a PlayfulHacker who only acted as TheCracker against those who threatened her loved ones, now she engages in her hacking of communications with the explicit purpose of insulting, demeaning, and threatening others, especially Fireteam Osiris.

* ContraltoOfDanger: Her voice is significantly deeper [[spoiler:in ''Halo 5'' whenever she is speaking to Fireteam Osiris]], especially in the contrast to the much higher-pitched 031 Exuberant Witness.

* EvilGloating: [[spoiler: A good amount of her dialogue in ''VideoGame/Halo5Guardians'' is this in some way or another. Whether she is [[WeCanRuleTogether explaining her motivations and goals to Blue Team]] or [[KickTheDog taunting Fireteam Osiris about being inferior Spartans]]. Both teams respond with ShutUpHannibal.]]
* FaceHeelTurn: [[spoiler: She is the BigBad of ''VideoGame/Halo5Guardians''.]]

* FauxAffablyEvil: [[spoiler: In ''VideoGame/Halo5Guardians'', to Locke and Fireteam Osiris.]]

* FirstLawOfResurrection: [[spoiler:At the end of ''Halo 4'', she sacrificed herself to save the Master Chief in a very touching farewell scene. By ''Halo 5'', she's already gotten better.]]
* FriendlyEnemy: [[spoiler: Despite her FaceHeelTurn in ''VideoGame/Halo5Guardians'', she still considers John and Blue Team to be her family.]]

* NotQuiteDead: [[spoiler:On the verge of death in ''Halo 4'', she fell into a slipspace rupture, and ended up at the Domain, which acted as, in her words, a "fountain of life" for artificial intelligences. She, unfortunately, CameBackWrong.]]

* PoweredArmor: [[spoiler:In ''Halo 5'', her holographic display no longer appears naked but instead appears to be clad in what strongly resembles the Spartan MJOLNIR armor, emphasizing her militaristic outlook and role.]]

* StalkerWithACrush: [[spoiler: Cortana becomes a ClingyJealousGirl in ''Halo 5'' and just ''knows'' John will understand ''everything'' after she kidnaps him to keep him all to herself for the next 10,000 years while she does her dirty work, and that John's insistence they're JustFriends is just because he just doesn't ''understand'' what she's doing.]]

* WellIntentionedExtremist: [[spoiler:She may have gone mad in ''Halo 5'', but she seems to genuinely believe that what she's doing is best for all beings in the galaxy, and certainly more well intentioned than [[KillEmAll the Warden Eternal]].]]

* {{Proud Warrior Race Guy}}s: Well, you can say that. The Humans were the first species since the Lekgolo to give the Covenant a real fight, [[spoiler:holding out long enough the Covenant to destroy themselves]]. Post-war, they actually eclipse most of the remaining Covenant factions in strength.

* BritishAccents: Doubles as a MythologyGag, since Cortana was originally envisioned as having a British accent.
