Tropes pertaining to the armies of Chorus, two factions fighting each other in seasons 11 and 12 but coming to a truce by the end of Season 12, in Red vs. Blue. All spoilers for the first fifteen seasons will be unmarked below.
Chorus is a planet located on the edge of colonized space, forgotten by the UNSC. Thanks to the manipulation of Charon Industries, a Civil War erupted between two factions, the New Republic and the Federal Army of Chorus. However, the conflict ended when Felix's true intentions were broadcast, and the planet of Chorus united to take down Charon Industries and its CEO, Malcolm Hargrove.
- Amazon Brigade: Simmons leads a group of these in the New Republic, much to his consternation.
- Archaeological Arms Race: Chorus was originally settled by the UNSC since they were interested in the records of Forerunner relics left on the planet.
- Badass Army: Are definitely a collective one by the end of Season 13.
- Bomb-Throwing Anarchists: The Feds accuse the Rebels of being this.
- Foil: To each other. The New Republic has incompetent soldiers with a competent leader while, the Federal Army has (seemingly) competent soldiers with an incompetent leader.
- Generation Xerox: Not their children, but the highest-ranked recruits of the New Republic all are very similar to their superiors. Overall, they are very similar to the Season 1 versions of their Captains. Details are in their own folders.
- Karmic Jackpot: After suffering through a brutal genocide and almost being manipulated by Charon Industries into killing themselves, by the end of Season 15, the Chorusans have become a significant and independent power in the known galaxy and are loaded with advanced Forerunner tech, even to the point where the UNSC eventually recognizes their sovereignty.
- La Résistance: The New Republic. A deliberate parallel is made to Star Wars. Later subverted in that the Rebels have apparently done some pretty nasty things, and the Federal Army itself is not so different in that they're trying their best and are in way over their heads too.
- Not So Different: To each other. They're both only barely keeping their heads above water during the Civil War, are just doing what they think is right, and have apparently committed countless terrible acts in the past. This is best shown in "Out of the Frying Pan," where Kimball and Doyle give near-identical Rousing Speeches to their troops in preparation for the (supposed) Final Battle.
- Obstructive Bureaucrat/Rules Lawyer: The Feds have this air about them, what with Doyle getting the position as General simply because he was the next in line and not an actually competent tactician or strategist by any stretch of the imagination. Miles Luna has said that if Felix had killed Doyle in "Off-Key," whoever would've been put in charge of the Federal Army would be someone who had never been introduced before that episode and would've been even less prepared for the job just because of how the original Chorus Constitution/government charter was written and the Feds feel they need to follow it to the letter.
- Order vs. Chaos: The Federal Army is Order, and the New Republic is Chaos.
- Population Control: Inverted. After they essentially suffered through a genocide due to both the Civil War and the war against Charon Industries, the Temple of Procreation was activated and the planet went through a massive population boom.
- The Remnant: The Federal Army is all that's left of the original Chorus colonial government.
- The Resenter: After Doyle's Heroic Sacrifice, the Feds temporarily became this to Kimball, believing that she just let him die.
- Teeth-Clenched Teamwork: The two sides declared a truce to oppose Charon together, but they still don't get along very well. They eventually bury the hatchet after Kimball's Rousing Speech in "All Or Nothing."
- Took a Level in Badass: Over the course of Season 13 the various factions of Chorus slowly go from Action Survivors barely managing to keep up with the Space Pirates to a fully realized Badass Army. This comes to a head in Episode 18 once the New Republic and Federal Army of Chorus finally bury the hatchet and agree to work together. Most of the army, now equipped with the Forerunner weapons from the Tower of Arms, ambush the Communications Tower and proceed to Curb Stomp the guards protecting it. Meanwhile a smaller force, composed of Dr. Grey and the Lieutenants, sneak back to the now empty Crash Site Alpha and manage to activate a Tractor Beam that drags the Tartarus into the Purge Tower.
- Undying Loyalty: Both armies are remarkably loyal to their leaders. It's more noticeable with the Feds since Doyle is actually a General Failure, but his soldiers are still unflinchingly obedient to him (with them all even becoming The Resenter to Kimball after he sacrifices himself in Armonia).
- Unwitting Pawn: To the Chairman, who was manipulating both factions to kill each other. It's a miracle, really, that the Blood Gulch Crew interfered with his scheme.
- Weapon of Choice: The vast majority of the Federal Army uses assault rifles while the New Republic all have the Designated Marksman Rifle as their standardized sidearm. After Tucker re-activates the Temple of Arms, though, they all swap them out for advanced Forerunner weapons.
General/President Vanessa Kimball
Initially the tan and blue leader of the New Republic. She was Felix's employer, until he betrayed her, and requests assistance from the Reds and Blues. In contrast to most of the series' female fighters, she is actually a nice woman who is very trusting of the Reds and Blues and Felix. She is not trusting of Doyle and the Feds on the other hand, and only thinks of the general first as a tyrant, then as a coward.
- Action Girl: While it takes a while to show, she rides at the head of the New Republic, personally leading the assault on the Federal Army and fighting to get to Doyle. She and Wash are also the ones to ultimately kill Sharkface.
- Aw, Look! They Really Do Love Each Other: She shows that she really does care for Doyle deep down with her emotional reaction to him staying behind in Armonia to blow up the reactor, even screaming at him to stop.
- Da Chief: She is noticeably (but justifiably) peeved at the Reds and Blues' lack of living up to their Living Legend status, though she defies the part that involves putting them down for their failures.
- Four Is Death: Inverted. The fourth leader of the New Republic after the former three were brutally murdered, but she was the only leader to survive the civil war.
- Jerk with a Heart of Gold: She can be tough, but she wants the people of Chorus to survive as much as everyone else. While she constantly bickers with Doyle after they join forces, it's shown that she genuinely cares for him when he sacrifices himself to hold back the Space Pirates.
- Leeroy Jenkins: In Season 13, though it's downplayed. Though she is open to plans, she is adamant and eventually leads her troops into an avoidable trap.
- Martyr Without a Cause: Her biggest flaw is that she believes one should fight to the death when all else fails instead of considering surrender, which Doyle himself calls her out on. She grows out of it after Doyle sacrifices himself.
- Meaningful Name: Kimball means "war chief" in Old Welsh, fitting for a former general.
- Reasonable Authority Figure: And, as of this point, the first female badass to not have a Jerkass side. Later, with a bit of prompting, she starts negotiating with Doyle. That said, she does still hold a grudge against Doyle and the Feds and takes reprimanding Doyle too far in Season 13 Episode 12, forcing Wash to tell her to back down. She proves it again in full-force through a Rousing Speech after Doyle's Heroic Sacrifice to unite the New Republic and the Federal Army to fight Charon Industries. She's this even more so in Season 15, as she's become the president of the whole planet and is trying to negotiate with the UNSC instead of fighting against them.
- Rebel Leader: Used to lead the New Republic. She now leads the planet Chorus itself as its president.
- Rousing Speech: After Doyle's Heroic Sacrifice, she gives a big one to rally and unite the two sides together to fight Charon Industries, simultaneously putting down the doubts the Federal Army had about her leaving Doyle to die in Armonia while encouraging both sides to bury the hatchet permanently so as to stop the Civil War from starting up again after Charon was defeated.
- Took a Level in Jerkass: She becomes much more rude, condescending and reckless in Season 13. Justified as she's being forced to work together with her sworn enemies, the Federal Army, and they're being backed into a corner by Charon Industries. Subverted after Doyle's sacrifice makes her realize she was wrong and that the two factions need to trust each other to survive.
- You Are in Command Now: Not as bad as Doyle, but she only received her role as the leader of the New Republic after the last three were brutally murdered. She eventually finds herself as the leader of all of Chorus's remaining soldiers, both of the Republic and Federal Army, after Doyle's Heroic Sacrifice.
General Donald Doyle
Initially the leader of the Federal Army of Chorus. He is a lot nicer than Locus, and is barely able to control him at all. He has also been manipulated into viewing the New Republic as terrorists trying to rule Chorus, which is far from true. He is hesitant to the idea of working together with the New Republic, but eventually agrees to do it for the Blood Gulch Crew, to whom he owes his life.
- Alliterative Name: Donald Doyle.
- Anti-Villain: Doyle may be a coward, but he's clearly struggling to keep the Federal Army going and doesn't seem to take any enjoyment out of the conflict.
- Apologetic Attacker: He didn't do the attacking, but he profusely apologized for Locus's method of getting Wash, Sarge, and Donut to the Feds' base.
- Beam Me Up, Scotty!:
Doyle: I believe it was the great William Shakespeare who said "courage is not the absence of fear. It is acting in spite of it." I don't believe those words have ever been more relevant.
- He gives some profound wisdom in Season 13, but misattributes its source to Shakespeare.
Epsilon: ...I don't think that was Shakespeare.note
- Later, he realizes this and prevents himself from using the quote as his Famous Last Words.
- Closest Thing We Got: Why he's the leader: he was the highest in the chain of command. It's really saying something about how bad the situation is when he was initially personal secretary of the Brigadier.
- Cowardly Lion: A major plot point in Season 13, as he realizes his own cowardice and does his best to become a true, heroic leader.
- When faced with the Sadistic Choice of either sending reinforcements to Kimball and the other troops who are pinned down, or to the temple to fetch the key that could destroy the planet, he Takes a Third Option and goes to the temple by himself to get the key, in spite of knowing that the enemy, who have more numbers than they previously thought, are heading in that direction as well. This is somewhat lessened by him losing the key because of his own cowardice shortly afterwards.
- He puts himself at risk by refusing to join the Reds and Blues on the Pelican while he had the chance (which would have led to the Space Pirates fleeing, making Armonia's destruction pointless), instead opting to rush into the city, infested with Charon's men, and personally set the reactor to detonate himself. When he is found and the controls are destroyed, he takes it upon himself to manually blow up the reactor, letting himself die in it along with most of the Space Pirates, finally redeeming himself in his own eyes.
- Cyber Cyclops: His helmet has this as a feature.
- Da Chief: The leader of the Feds.
- Dirty Coward: He's "a leader, not a fighter." This is the cause of his character arc in Season 13, leading him to admit that he's a horrible leader in Episode 12. To redeem himself for this, he ends up sacrificing his life for the greater good.
- Evil Brit: Not exactly Wyoming, but he's this from the perspective of the Rebels. Until they realize both sides are being manipulated.
- Evil Gloating: Instead of immediately attacking Kimball and the rebels when they fall into the trap the Feds had laid at Armonia, he launches into a tirade about what a wicked, blood-thirsty person Kimball is. Strictly speaking this is more self-righteous gloating than flat out evil gloating because neither side in this conflict is really villainous. Also, it's a rare example of Evil Gloating ending in a positive outcome. The whole fact that the entire Civil War is being stage-managed by the Mercs very nearly comes out right there and then until intervention by the Space Pirates triggers the battle proper, and the several minutes Doyle and Kimball spent arguing shortened the fight, almost certainly reducing the number of needless deaths that would have resulted.
- Face Death with Dignity: He remains remarkably calm as he manually rigs Armonia's nuclear reactor to explode."This is General Donald Doyle, signing off."
- Famous Last Words: Before he dies in Episode 16 of Season 13:Space Pirate: (smugly) Heh. Any Last Words?, "general?"
Doyle: (calmly) I'd like to quote the great William Shakespeare... but to tell you the truth, I don't actually think he said it.
- Greater-Scope Villain: Averted. It's almost a subversion, given that he's the leader of the party the viewer is led to believe are the villains for the first half of the trilogy and seemingly behind Control and Locus. But by the time we meet him, he's turns out to not be that bad of a guy, and it's then revealed that both Control and Locus are part of a third party playing both sides. Doyle didn't even know that Control existed.
- Heroic Sacrifice: He begins to put himself at risk in Season 13 to prove to himself that he's not truly a coward, eventually sacrificing his life by manually destroying Armonia's reactor and killing over half of the Space Pirates.
- Meaningful Name: His first name, "Donald," means "world ruler" in proto-Celtic, which is rather appropriate since he's the leader of The Remnant of what's (technically) the legitimate government of Chorus.
- Modern Major General: He has no actual combat experience, and relies largely on Locus, whom he cannot control. Hell, even Donut considers him to be a wuss.
- More Expendable Than You: He tells Kimball that she's a better leader and thus more important to the cause than he is, so he should be the one to die in the reactor.
- Nice Guy: Downplayed. He still has his faults and is largely a well-meaning but incompetent wimp, but he truly means well and is sincerely dedicated to helping save Chorus.
- Non-Action Guy: Flat out says he's not the combat type. At first this makes him seem like a Non-Action Big Bad, but he's really nothing of the sort.
- Politically Incorrect Hero: Heavily downplayed. He refers to Kimball as "Miss" instead of using her proper rank of "General," but that admittedly might be less sexism and more his distaste for the New Republic - a.k.a. the group that he's seen as terrorists for the last few years as he's been leading the Feds.
- Protection Mission: When Felix obtains the Great Key just to find that it will only function upon Doyle's death, the armies of Chorus place him under permanent protection and are forced to guard him at all costs.
- Reasonable Authority Figure: He's willing to free Wash and the Reds, and apologizes for the actions of Locus. Later, with a bit of prompting, he starts negotiating with Kimball.
- Redemption Equals Death: He views his Heroic Sacrifice as him finally making up for having been a coward and a poor leader.
- Sissy Villain: Washington raising his voice was enough to make him faint. Subverted, as the Federal Army aren't villains.
- Stiff Upper Lip: Attempted. He tries to paint Chorus as salvageable and look on the bright side of things, but can't really downplay how utterly awful everything's gotten and how out laughably of his depth he is.
- Stupid Sacrifice: Defied. Doyle knew that blowing himself up along with all the Space Pirates in Armonia would give Felix control over the Great Key, but he sincerely believed that the rest of the heroes would be able to defeat Felix nonetheless. Indeed, the Chorus troops' plan to destroy the Purge went off without a hitch precisely because Doyle, in Church's words, sent half the Space Pirates to hell.
- You Are in Command Now: He was the highest ranked person left after all the other people ahead of him were killed or ran off. He was the Brigadier's secretary. And when he sacrifices himself in Season 13, he tells Kimball to lead the troops since he knows that she can stop the Space Pirates.
The Lieutenants/Rescue Team
Lieutenant John Elizabeth Andersmith
A rebel soldier of Caboose's Blue Team who is shown to be fiercely loyal to both his Captain and the New Republic. He believes that Caboose is a wise and noble man, somehow. In Episode 4, he is chosen for the elite team to be sent on the rescue mission.
- Actually Pretty Funny: Ends up admitting this about their training mishaps.
- Blind Obedience: Bitters describes him as having this in the Ultimate Fan Guide - probably the reason for his Undying Loyalty to Caboose.
- Call-Back: His name, fully revealed in the finale of Season 12, is a reference to the fake name used in Epsilon's world.note
- The Big Guy: Out of the Lieutenants, he's the physically strongest and has the most stamina.
- The Comically Serious: He'd be relatively normal if it weren't for the Undying Loyalty below.
- Consummate Professional: Actually tries to talk like someone in the military, which annoys the Reds and Blues.
- Embarrassing Middle Name: Averted - doesn't seem to find anything embarrassing about his middle name.
- Expospeak Gag: Does it all the time once he becomes part of Chorus' law enforcement, much to Bitters' annoyance.Smith: Just a few more inquiries, ma'am. Did you attempt to witness any other particular individuals in the general vicinity of the area in which the crime scene was alleged?Bitters: (sighs) Jesus Christ. What he means is, did you see anybody?
- Genius Bruiser: According to Bitters's account found in the Ultimate Fan Guide, he's both highly intelligent and in peak physical condition. The latter is demonstrated by his being the only one not winded or outright exhausted by the many, many laps Washington makes them run. The former is largely an Informed Ability.
- Gender-Blender Name: His middle name, "Elizabeth," is typically a feminine name.
- Generation Xerox: Like Caboose, Andersmith has Undying Loyalty to a man who doesn't quite match his mental image, and has a Charles Atlas Superpower.
- Horrible Judge of Character: He thinks Caboose is one of the wisest men he's ever seen. Caboose. He also gave his grenades to him.
- Metaphorgotten: Translates Caboose's speech to something greatly inspiring. Except for the part about replacing the water fountains with kool-aid. That part just sounds awesome.
- Nice Guy: Easily the most civil and cooperative of the Lieutenants.
- Undying Loyalty: Believes Caboose is "the wisest man he's ever known."
Lieutenant Katie Jensen
Tucker: Simmons, what the fuck is this?
Simmons: It was either her or the really hot one that plays volleyball!
Tucker: Then what the fuck is this?!
Lieutenant of the all-girls Red Team under Simmons's command. She talks with a lisp and makes Simmons only slightly less uncomfortable than the other girls. In Episode 4, Simmons chooses her over his lieutenantnote for the rescue mission.
- Action Girl: She is still a soldier in the New Republic, after all.
- Adorkable: Her speech impediment and the fact she looks up to Simmons make her quite dorky, but adorable nonetheless.
- Amazon Brigade: She's initially on a team full of girls, much to the distress of Simmons.
- Berserk Button: She isn't too happy after finding out that Palomo stares at her butt, especially when this is caught on video.
- Drives Like Crazy: Continuing the issues they seem to have with pedals. In Season 13, this is taken Up to Eleven, with her causing a multiple car pileup while driving at about five miles an hour, to Simmons' immense confusion.
- Generation Xerox: Like Simmons, Jensen is respectful to authority, though she seems to be more in genuine awe of the Blood Gulch Crew, especially Simmons himself, than a sycophant. She's also a wimpy nerd that knows lots of science facts.
- Nice Girl: A very empathetic and cheery person to be around.
- Ship Tease: Is seen holding hands with Palomo in one of the final scenes of Season 13's finale, and affectionately calls him "Charlie" in Season 15.
- The Smart Guy: Of the Lieutenants. She also helps Simmons rig up a massive smoke screen to grant the besieged Fed and Rebel forces a chance to escape Crash Site Alpha in Season 13.
- Speech Impediment: Talks with a lisp and almost chokes on her own spit during her introduction.
- Wrench Wench: Bitters notes how skilled she is as a mechanic, and wonders what she could have accomplished if the war wasn't in the way.
Lieutenant Antoine Bitters
Lieutenant of Gold Team under Grif's command. He's Grif's favorite member of the team, due to Grif seeing him as a loose cannon, and a maverick. He is chosen over Matthews for the rescue mission.
- Ascended Extra: In a sense, with his journal entries being prominently featured in The Ultimate Fan Guide.
- Broken Bird: The Ultimate Fan Guide shows that he's a Rare Male Example.
- Deadpan Snarker: He's one of the people sane enough to realize that the Blood Gulch Crew are not as awesome as their hype may claim. His dialogue reflects this.
- The Fatalist: Bitters is pretty sure he and everyone else on Chorus is going to die a horrible death, and has resigned himself to this fact.
- Generation Xerox: Bitters is a lazy and cynical Sour Supporter just like Grif. Grif even starts treating Bitters the same way Sarge treats him (much to his horror).
- Hidden Depths: His cynicism comes from the fact that he's old enough to remember what life was like before the war, and he can even be surprisingly philosophical when in private. In one of his journal entries, he laments that Jensen's mechanical genius can only be channeled into warfare, and wonders what she might have accomplished if she had grown up in a peaceful world.
- Ironic Name: His first name is descended from the French words for "highly praise-worthy." He's a Sour Supporter for both Grif and the rest of the Blood Gulch Crew.
- Jerk with a Heart of Gold: Bitters acts cynical and lazy most of the time, and is quick to point out the down side of things and flaws in others. That being said, he still deeply cares about his teammates and leaders. He was shown to be physically upset when Felix lied to him and the others that the Reds and Blues were deadnote . Additionally, there's clear panic in his voice when Matthews is shot by a Mantis with him even staying by his side while Dr. Grey is healing him in the finale of Season 13.
- Meaningful Name: As might be guessed from the above tropes, he is quite a bitter person.
- Mistaken for Badass: Grif chooses him for the squad because he thinks he's a cool, competent, maverick. He's quickly revealed to be what is in essence a younger version of Grif, which is anything but.
- Older Than They Look: He generally doesn't seem to be that much older than the other Lieutenants, but according to The Ultimate Fan Guide, he actually remembers what life on Chorus used to be like before the Civil War while they're all too young to recall it.
- Only Sane Man: Of the Lieutenants.
- Sour Supporter: Follows Grif's commands without question, but seems very cynical about their chances and isn't above pointing out his commanding officer's flaws.
- Vitriolic Best Buds: With Palomo due to the latter's ditzy behavior often getting on his nerves.
Lieutenant Charles Palomo
Simmons: Is... that your fun fact?
Palomo: Oh, uh... oh! I'm the only surviving member of Green Team. Suck on that!
Tucker: ...I fucking hate you, Palomo.
Palomo is a New Republic rebel soldier of Tucker's Green Team. On the infiltration mission in Episode 2, he is told to wait outside by Tucker, who worried he would get everyone killed if he came inside. However, in doing so, Palomo becomes the Sole Survivor of the team when Rogers and Cunningham both die. He is only chosen by Tucker for the rescue mission for this reason.
- Adorkable: He uses hand binoculars, for Pete's sake!
- Anguished Declaration of Love: To Jensen after Kimball's speech in Season 13:Palomo: I've always loved you, Katie!
Palomo: Misread that, alright! Let's kill the bad guys!
- Butt-Monkey: Readily admits he's probably the worst soldier in his entire squad, which might be an Actor Allusion based on how the voice actor is treated around the office (in jest).
- Casanova Wannabe: "Slayer of women, wooer of evil. ...Wait."
- Covert Pervert: His biggest issue with the helmet-cams is that people will realize he's staring at Jensen's butt.
- Crouching Moron, Hidden Badass: It's early on and downplayed, but Palomo, despite being referred to as the worst soldier out of the Lieutenants and overall coming off as kind of ditzy, was able to calmly dodge the sniper rounds Locus was firing at him - something neither Wash or Sarge could do.
- The Ditz: Has his moments, often getting easily distracted from what's currently happening.
- Generation Xerox: Like Tucker, Palomo is a laid back Casanova Wannabe that likes to be the center of attention (though he's far less of a dick).
- Hero Worship: For Tucker.
- Irony: His relationship with Tucker is a reflection of Tucker's relationship with Church during the first few seasons of the series.
- Meaningful Name: His last name is a Spanish word for "dove." He's the Generation Xerox of Tucker, who considered himself a Technical Pacifist back during The Blood Gulch Chronicles.
- Nice Guy: Overall, Palomo's a much friendlier (and goofier) person that Tucker ever was during the first few seasons of RvB.
- Sarcasm-Blind: Which might not make him the best lieutenant for Tucker.
- Ship Tease: Is seen holding hands with Jensen in one of the final scenes of Season 13's finale, and she affectionately calls him "Charlie" in Season 15.
- Sitcom Arch-Nemesis: Tucker fucking hates Palomo. That being said, a lot of it is heavily implied to be in jest to a certain degree.
- Sole Survivor: Of Tucker's Green Team by the end of Episode 2. He doesn't seem bothered by it, and even brags about it during the introductions.
- Vitriolic Best Buds: With Bitters, in part since he's often blind to the latter's snark.
- Wide-Eyed Idealist: Shows traits of this in Episode 8 of Season 12, after his Captains leave on the rescue mission without him.Palomo: They'll come back. I know they'll come back.
Doctor Emily Grey
Initially the disturbingly cheerful doctor of the Federal Army of Chorus. She fixes up Wash and the others after Locus's attack. However, her cheerfulness is a mask for her true insanity, as evidenced when she mutilates a Space Pirate off screen, and manages to keep him alive so she can gather info on the Pirates.
- Adorkable: Mix this in with a healthy dose of Comedic Sociopathy and you have Dr. Grey!
- Ambiguous Disorder: There's clearly something wrong with her mentally speaking. Word of God seems to imply that she's a Shell-Shocked Veteran due to the Chorus Civil War.
- Anti-Hero: Even though she is on the side of the heroes and remains polite, cheerful and friendly, she is very good at torturing people, disconcertingly bloodthirsty, and is actually quite insane.
- Ax-Crazy: Undoubtedly one of the craziest people in the entire show up to that point, considering how her Mutilation Interrogation methods and cheerful nature unnerve even Sarge and Carolina. Thankfully she remains on the side of the heroes, but that doesn't make them any less scared of her. In the season finale of Season 12, Epsilon even outright calls her "the lunatic".
- Break the Cutie: It's implied that seeing all her comrades slaughtered in "Cloak and Dagger" did this. She doesn't show this.... directly.
- Based on an interview with Arryn Zechnote , much of Grey's personality is the result of the years of the Civil War, and her being a doctor in it, making her a full-on Broken Bird.
- expanded upon by Miles Lunanote , saying that an early plan was for Epsilon to find Grey's journals during the evacuation of Armonia, and play them for Kimball to help humanize the Federal soldiers. They would start off resembling the beginning of the journal she was making during the "field trip" (this was originally Foreshadowing), but as the war went on, she could be heard slowly breaking and retreating into her "happy place" until there was no escaping it. Further
- Bunny-Ears Lawyer: Sure, she's disturbed and disturbing whenever she speaks (even deciding to hold talks about patients while performing autopsies). But Grey is also an incredibly effective doctor, to the point once Wash gets wounded he's dropped at her door.
- Child Prodigy: She was considered one when she was eleven as she was able to correctly diagnose every patient on House, M.D. within the first five minutes. Her parents apparently tried to get her to watch Grey's Anatomy, but she said it was too "trite".
- Cultured Badass: She likes opera, singing it while torturing the son of a bitch who killed her friends, and listening to it in her office.
- Cold-Blooded Torture: If you consider singing cheerfully as she inflicts it to be cold-blooded.
- Cyber Cyclops: A feature of all the Federal Army's helmets. This isn't the case in Seasons 15-17, though, as the same helmet isn't in Halo 5.
- Dissonant Serenity: She gets back to her cheerful self pretty quickly considering she watched all the soldiers at her base get killed and is now being hunted by people trying to kill everyone on her planet.
- Distaff Counterpart/Foil: To Doc, as they are both cheerful medical officers garbed in purple armor that have a few screws loose and tag along with the Reds and Blues after initially being from an outside party. But unlike Doc, who is utterly incompetent at his job and pacifistic to the point of refusing to make gunshot sounds (well, at least till O'Malley got a hold of him), Grey is both an incredibly confident Mad Doctor and a Torture Technician.
- Ditzy Genius: She has an IQ of 240, but seems rather quirky.
- Expy: Miles Luna and Arryn Zech have both said that she was heavily based off of Dr. Patricia Tannis from Borderlands, albeit with the main difference between the two characters being that Grey became a complete extrovert while Tannis became an utter introvert in response to the traumas that they suffered through.
- Fetish: People with mental or emotional issues, if her reactions to the Blood Gulch Crew are any indication."Psychoanalyses for everyone!"
- Genki Girl: She's very full of energy and very excited about her job. Including some extras pro bono.
- Horrifying the Horror: O'Malley, the Big Bad of The Blood Gulch Chronicles and the literal amalgam of both Church and Doc's rage, is absolutely terrified of her after ten seconds of interaction.
- Improbably High I.Q.: It's 240.
- Kick the Son of a Bitch: She gleefully tortures one of the Space Pirates for information. Considering that he and his allies murdered all her friends and are planning to commit mass genocide though, it's hard to feel any sympathy for him.
- Large Ham: Completely nuts, and totally enjoying herself ("Oooooh, you're hostile! I'd love to psychoanalyze you!"). To the point she sings opera while interrogating a pirate who screams in pain.
- Mad Doctor: She's very good at patching people up, but... somewhat disturbing in how she talks about wounds. And that's not even getting into her methods of interrogation, which scares even Sarge and Carolina.
- Meaningful Name: Her last name being "Grey" can serve as a good indicator of her having a darker side than the cheery Genki Girl she seems to be on the surface.
- The Medic: Well, technically she's a doctor, but she still fixes up the Fed soldiers. She also loves cutting limbs and would make The Medic proud based on Dr. Grey's ways of making people talk.Donut: Oh, a doctor! That's like a medic who saves people!
- Multidisciplinary Scientist: A surgeon by training, but she's also apparently a psychoanalyst and spent some time in archaeology. As she says:"A prodigy can only cut people open so many times before she needs to find a hobby."
- Mutilation Interrogation: Her method of getting information, to the point of having to put victims back together when shes done. It tends to work.
- Nice Girl: Once you look past how absolutely terrifying she can be, she's actually quite friendly and seems to sincerely want to help Chorus, her friends, and her patients (even if that help might consist of Unwilling Roboticisation).
- Nightmare Fetishist: She's awfully eager to amputate limbs, and is excited by Washington's neural implants.
- No Badass to His Valet: She's the only person to not be intimidated by Locus, who actually shows her some respect. Episode 15 of Season 12 reveals why.
- She also doesn't lose her cheer when around Carolina, even calling her "Sweetie" as she's patching up the Super Soldier's leg.
- Odd Friendship: While she has a fondness for all of the Blood Gulch Crew, she seems to get along the best with Sarge and Wash.
- O.O.C. Is Serious Business: In "The Federal Army of Chorus," she was all chipper and upbeat, even when talking about rather morbid subjects. But in "Cloak and Dagger," as Locus and Felix's troops slaughter her comrades, she ducks for cover and whispers, "Oh, dear."
Donut: (after Epsilon grimly suggests they could just leave Chorus behind) But... we can't just leave!
- She's also atypically serious in "Multiple Choice," quietly telling the Reds and Blues that it's perfectly fine if they want to leave Chorus as it isn't their fight.
Dr. Grey: Yes, you can. This isn't your responsibility! You all held up your end of the bargain. You helped us fight. You saved your friends! (sadly) So now all that's left is for you to... go home.
- Properly Paranoid: Despite not being a soldier, she's still wearing armor since everyone who isn't has already been killed in the Civil War.
- Sixth Ranger: She becomes this to the whole Blood Gulch Crew after escaping with them from Locus and Felix's ambush up until Tucker exposes Felix.
- Stalker with a Crush: To Doc/O'Malley, who is terrified of her."Running only makes me want you more!"
- Stepford Smiler: She seems a little bit too cheerful for it to be natural. Confirmed in The Ultimate Fan Guide, which specifically states that her cheerful demeanor is a method of coping.
- Spanner in the Works: Her presence with the Blood Gulch Crew in the second half of Season 12 not only has her convince them to all stay and fight for Chorus, but she proves to be vital in helping them reveal to all of Chorus that the Civil War is being stage-managed by the Mercs.
- Surrounded by Idiots: Averted. Despite being much smarter then almost everyone else on the planet, she doesn't consider any of the Blood Gulch Crew beneath her or as just a bunch of idiots as many people do. If anything she finds their antics entertaining and worthy of analysis. She even described them as being "the most fascinating group of individuals [she] has ever had the pleasure of meeting!"
- Too Spicy for Yog-Sothoth: Tucker considers her too loony to hit on.Tucker: (in a terrified tone to Caboose) Don't ever stick your dick in crazy.
- Torture Technician: The only reason she isn't an Exalted Torturer is because she genuinely disturbs her teammates with her methods.
- To the Pain: Poor Zachary.
Matthews is a New Republic soldier on Grif's Gold Team and, according to Grif and Bitters, a total kiss-ass. His request to join the elite team with the other named soldiers is ultimately denied because of this fact. He is wounded in the Season 13 finale by one of the Chairman's Mantises, and treated to by Dr. Grey.
- Butt-Monkey: Gets constantly put down and insulted by Grif, thrown around by an uncontrollable Ghost, and even shot by a Mantis.
- Drives Like Crazy: To a lesser extent than Jensen, but he has extreme difficulty controlling a Ghost during the raid on the Communications Temple. He's still able to put it to use, however.
- Morton's Fork: Agree with Grif, be called a kiss-ass. Disagree and Grif doesn't like him anyway.
- Professional Butt-Kisser: Gives Simmons a run for his money.
- Sitcom Arch-Nemesis: Much like Tucker hates Palomo, Grif hates Matthews.
- The Unfavorite: Due to him being a kiss-ass, Grif dislikes him.
- Took a Level in Badass: Despite being a cowardly kiss-ass, he manages to save the Fed Gunman from a Charon soldier and even take down a Mantis using a Ghost. Too bad he's not that great at controlling it.
- What Happened to the Mouse?: Doesn't reappear in Season 15.

- Famous Last Words:
- Gone Horribly Right: The plan to disguise himself as a Fed ends up being so convincing that some other Fed troopers order him to disarm one of the bombs for them, resulting in his death.
- Only Sane Man: He's the only soldier who seems to realize that the Reds and Blues are... less experienced than they were made out to be.
