History Trivia / RedVsBlue

* IKnewIt:
** People were so sure that C.T's initials stood for Connecticut that it's been treated as practically canon as far back as season seven. However it is only in Season 9 that Connecticut's full name is first used on screen.
** The idea that the [=C.T.=] first met in ''Recreation'' wasn't actually Agent Connecticut has been tossed around ever since Washington revealed that C.T. was a woman.
** Fans also successfully called an Engineer being the contents of the Sarcophagus.
** With all the theories floating around about the Mysterious Blue Guy, ''someone'' was going to get his identity right; the crowd of fans that guessed he was Flowers were correct, though fewer also guessed he was also Agent Florida.
** Early in Season 15, the vast majority of fans were assuming that the Reds and Blues the audience initially saw were fakes. They were correct. Dylan Andrews even deduced this through the same reasoning as the viewers did (Sarge doesn't have his shotgun, Tucker has a sniper rifle, etc).
*** Speaking of Season 15, both ''The Ultimate Fan Guide'' and the same season confirm that Sarge was a former member of [[ElitesAreMoreGlamorous the Orbital Drop Shock Troopers]] before he eventually became a Simulation Trooper. While ''Relocation'' had Simmons noting Sarge used to "jump out of ships during the Great War," Season 15 and The Ultimate Fan Guide explicitly state that Sarge used to be an [=ODST.=]
** Many fans also predicted TheReveal in ''The Shisno Paradox'' that the Cosmic Powers were really [[RoboticReveal hyper-advanced A.I.s]] utilizing a {{God Guise}}.
** ''Singularity'' confirms that [[spoiler:[=479er=] was the voice of "Recovery/Freelancer Command" heard during ''Recovery One'' and ''Reconstruction'']]. While many had already assumed that this was true, it wasn't until ''Singularity'' that the two characters were confirmed InUniverse to be the same person and not just a case of two different characters with the same voice actor.
** A few episodes into ''Zero'', the fact East was subject to experiments and was a glitchy {{foil}} to Phase led to the speculation that Phase was the real deal, East was a duplicate. [[spoiler:Sure enough, East is a LiteralSplitPersonality.]]

** Once Season 8 premiered, both the Rooster Teeth website ''and'' [[Website/BlipTv the entire video service]] crashed.

* TheWikiRule: [[http://rvb.wikia.com/wiki/Red_vs._Blue_Wiki Red vs. Blue Wiki]].

* CelebrityVoiceActor: A surprisingly high amount, including Ed Robertson from the Music/BarenakedLadies as Captain Butch Flowers (somewhat fitting given that the Barenaked Ladies' entertainment style is rather similar to Rooster Teeth's), Creator/ElijahWood as Sigma, Creator/AmberBenson as Female Grif, [[Creator/ProZD SungWon Cho]] as King Atlus Arcadium Rex, and Creator/RiccoFajardo as Genkins. According to WordOfGod, it apparently pays to have friends who are friends with celebrities.

** Some later voice actors too, such as [[http://lordjazor.tumblr.com/post/160929534499/thanks-for-voicing-spencer-he-is-the-biggest Jason Marnocha (Spencer Porkinsenson)]], Creator/DallasReid ([[https://twitter.com/FortWorthReid/status/866325049233608705 Buckey]]), and [[Creator/ProZD Sung-Won Cho]] [[https://twitter.com/prozdkp/status/996795038418993152 (King Atlus Arcadium Rex)]]. A sideways case is [[https://twitter.com/ActingMalconian/status/1328479639367389184 Michael Malconian]], who [[TheOtherDarrin voiced Caboose]] in ''WebAnimation/DeathBattle''.

* ReferencedBy:
** ''FanFic/EventHorizonStormOfMagic'' (a MassiveMultiplayerCrossover of ''Literature/TheLordOfTheRings'', James Cameron's ''Film/{{Avatar}},'' Nickelodeon's ''WesternAnimation/AvatarTheLastAirbender'', and ''[[TabletopGame/{{Warhammer}} Warhammer Fantasy Battles]]''):
*** The Wildcat armored car is illustrated by a picture of a Warthog from ''Halo''. Grif complains that the vehicle looks more like a puma - a kind of wildcat.
*** One of the Orcs guarding the Towers of the Teeth muses "You ever wonder why we're here?" His friend then contemplates aloud how it's "one of life's great mysteries."
** ''Fanfic/TheLastSpartan'' (an AlternateUniverse ''Franchise/{{Halo}}''[=/=]''Franchise/MassEffect'' crossover FusionFic):
*** Cortana attempts to alter her holographic avatar at one point to help disguise her appearance. One of the changes has her changing her avatar's color to pink. When the Master Chief points this out to her, Cortana responds by musing that she thought it was actually "lightish red."
*** At one point, Wrex calls Shotgun on the Warthog, and N'tho says "Shotgun! Wort!"
** ''Fanfic/ASpartanInWesteros'' (a ''Halo''[=/=]''Series/GameOfThrones'' crossover fanfic):
*** At one point, the Starks muse over the animal ThemeNaming of [=UNSC=] vehicles and comment on the Warthog's lack the tusks of the creatures they are familiar with. They then state that the Warthogs actually share more similarities with the mountain lions (or pumas) native to the North.
*** One chapter begins with two members of the Night's Watch and two Wildlings basically re-enacting the "You ever wonder why we're here?" scene from the first episode of the series.
** In ''Videogame/WorldOfWarcraft'', the Bloodgulch stronghold has a gluttonous orc named Griff.
** There's even some delightfully recursive examples going back into ''Halo'':
*** There is a rare line on the level "Outskirts", in ''VideoGame/Halo2'', where when under attack, a [=UNSC=] Marine will yell "I'll pull your skull right out of your head and beat you to death with it!" This is a reference to the CruelAndUnusualDeath of Private Jimmy at the hands of Tex.
*** One of the notes on the flags used in the later games' "Capture the Flag" multiplayer sessions mentions that it's "right next to the headlight fluid."
*** In ''Literature/HaloGlasslands,'' a Marine mentions that Sangheili just sounds like "Blarg! Honk!" to him. Additionally, the AI Black Box calls Evan Phillips "Phyllis", which was (supposedly) the original name of Sheila.
*** In ''VideoGame/HaloReach'', Elites will sometimes clearly yell "Blargh!" or "HONK!" when fatally wounded. Additionally, Emile (a member of Noble Team) seems to have been heavily inspired by the Meta in both their character design and personality.
*** In ''VideoGame/Halo5Guardians'', the description for the [=HCS=] Contender Red weapon skins reads "Let's all take dying as an open action item", referencing a quote from Simmons in the Season 2 finale "K.I.T. B.F.F.".
*** The Master Chief Collection version of ''Halo 2'' includes an achievement called "Six pedals, four directions", which is unlocked by having the Arbiter drive a Scorpion. This is a reference to a line of Caboose's from the Blood Gulch Chronicles, where he asked why the tank had six pedals if there's only four directions (and referenced later in season 8, where we actually see a Warthog with six pedals).
** In ''VideoGame/RedDeadRedemptionUndeadNightmare'', the achievement for killing a Chupacabra is called "Chupathingy."
** In ''VideoGame/GearsOfWar'', there is an achievement entitled "Is it a Spider?", which is awarded for sticking 100 enemies with grenades in multiplayer (referencing the Season 1 episode "Knock, Knock. Who's There? Pain").
** Rooster Teeth's later show ''WebAnimation/GenLock'' had both lines of the famous opening line in separate episodes ("It's one of life's great mysteries, isn't it?" and "Do you ever wonder why we're here?").
** ''Webvideo/HonestTrailers'' both gave ''Halo'' the title ''Red vs. Blue: The Videogame'' and their recap of ''Series/Halo2022'' concluded that viewers were better off watching the machinima.

* WhatCouldHaveBeen:
** A character introduction video that Burnie Burns created in preparation for the pilot episode was based around heavy action and extensive violence. However, Burns ended up taking inspiration from ''WebAnimation/HomestarRunner'', ''WebComic/PennyArcade'', and (to a lesser extent) ''Series/MysteryScienceTheater3000'', resulting in the pilot's script being shifted to focus on situational comedy instead.
** According to WordOfGod, there was originally a concept in which the characters, in preparation for battle, would call out [[ByThePowerOfGrayskull "Go Red/Blue for battle!"]] This would trigger a TransformationSequence in which the character's armour would change to the standard red or blue, making the battles appear more like actual multiplayer games.
** The story was originally going to be about the Reds, with Church and Tucker always observing from the cliff and making snarky comments, a la JustForFun/StatlerAndWaldorf.
** Most famously, ''Red vs. Blue'' was only supposed to last six episodes. However, Burns and Hullum kept getting so many new ideas (such as Donut having pink armor) that they wanted to try out that they kept pushing back the planned end-date before they decided to actually make [=RvB=] into a proper web series.
** According to the Season 2 commentary, Doc was going to be a reporter/journalist when he was first conceived but because of where his character was going (eg. [[DistressedDude kidnappings]]) it was seen as hitting too close to home considering the real wars in the Middle East happening at the time.
** The now-iconic helmet filters were originally never going to be used for the characters. However, when the series had just started production, Gus Sorola (the voice actor for Simmons) had moved to Puerto Rico and had to record his dialogue over the phone. Burnie Burns then had to add voice filters to everyone so as to keep the audio consistent.
** There were plans to give the Reds' Warthog be a character in the same vein of the Blues' with Sheila in the Scorpion Tank. The idea was to have the Warthog have a similar personality to Speed Buggy.
** Originally, Sarge's animosity towards Grif would have ended [[ItMakesSenseInContext after Sarge was revived by Grif's CPR for a headwound]]. The talk Church would have had with Sarge would have convinced him to lay off and the two would have treated each other better. They decided it wouldn't work and, instead, Sarge chews Grif out for how he was saved.
** The character who captures Church and Grif at the end of Season 2, Max Gain, was supposed to have a much larger role in Season 3. But given the script wound up very condensed so as to make the show progress the plot while still moving to ''Halo 2'' the same day the game hit stores, most of his appearances were cut.
** Commentary reveals that Sister was originally not meant to be portrayed as the... ah, "girl of questionable morals, standards, and intelligence" that she is. The writers had originally intended to depict her as a kind-hearted, but naive girl-next-door type, but that was before they interviewed Rebecca Frasier. The writers then played a joke on Frasier during auditions--they kept adding more and more vulgar jokes into the scripts to see when she'd ask to stop reading. ''She didn't,'' and that's how they discovered she was willing to say pretty much anything in her lines, whereupon they picked her for the role and Sister was rewritten to be a "loud slut" instead.
** Doing the AnimatedAdaptation was an ambitious idea, but the crew just didn't have the money and time for it.
** The commentary track on the ''Revelation'' DVD suggests that Grif [[YouKillItYouBoughtIt was originally going to take up the Meta's Brute Shot]] as his weapon (as he's noticeably the only member of the main cast not to have one). They decided not to go with this idea, however... Well, at least until he decides to help save Carolina and Epsilon in Episodes 20 and 21 of Season 10. But then the weapon unfortunately became unavailable in the ''Halo 4'' engine, meaning it could not be used for Seasons 11 & 12, and was {{Hand Wave}}d that it was confiscated by the UNSC between Seasons 10 & 11.
** There exists a deleted scene, fully animated but unused, of the Meta killing Agent Washington with the Warthog by splitting him in half. This scene would have been used in the finale of Season 8.
*** Speaking of the Season 8 finale, the original script for the episode ended with the ''Halo: Combat Evolved'' engine being used for [[InsideAComputerSystem the "inside" of the Epsilon Unit]] (likely to reflect it serving as a BookEnds for Church's character arc up to that point). This was changed early on due to Bungie approaching Rooster Teeth with early access to ''VideoGame/HaloReach'' and letting them use it for the Epsilon Unit.
** ''Revelation'' was originally going to be titled ''Resolution'' - Burns refers to it as that on the ''Recreation'' DVD commentary (even joking that the DVD would become a collector's item if the name changed).
** An unused fight scene for Season 9, but that was later updated for use in Season 10, would've had Carolina's armor completely break off after chasing the Sleeveless Insurrectionist, having a fight in a subway that would've ended with Carolina using her GrapplingHookGun to [[OffWithHisHead decapitate the guy]].
** An early idea for the "Mysterious Blue Freelancer" was that it was Sarge, he was silent all that time because his helmet mike was broke, and at the end of the season, they would give him a red helmet, allowing them to reveal his voice. They then decided that making it Flowers would be better.[[note]]As per the [=RvB=] panel at RTX 2016[[/note]]
** Early in the development of Season 11, Locus and Felix, both in green and grey armor, were going to be introduced as villains, which changed when Miles decided to have them be PlayingBothSides. Additionally, both Locus and Felix were going to be introduced later into the season, but Luna decided to speed up their introductions so as to get the plot moving forward at an increased pace.
** Felix was originally going to be called "Leon," but both Hullum and Burns thought it sounded too much like "Leonard" (as in, "Leonard Church") and so asked Luna to give him a different name.
** In an interview on [=AfterBuzz=] TV, Miles Luna revealed that an early plan was for Kimball to lose it when Felix's betrayal is revealed and shoot Doyle, and then be shot down herself.
** Early plans for Episode 8 of Season 13 were to actually show Tucker's test in the alien gateway, and to have Dr Grey go in too, but time constraints forced them to cut both sequences.
** Season 14 had quite a few episodes and arcs that had to be scrapped, though it's possible they'll [[RefittedForSequel be able to make these happen eventually.]]
*** One episode gathered the main cast together to do a live reading of Season 1 Episode 2 while drunk. First, they would would read a new script with the Reds getting a supply of alcohol instead of the Warthog. Then, they'd have to recite the original dialogue from memory. Predictably, it went off the rails, and the episode wasn't aired. It wasn't until a year later that they released a version of it for FIRST members as a reward for FIRST Week.
*** Burnie Burns planned to write an episode, but according to him, it just didn't pan out. An interview with [=AfterBuzz=] TV implied that he wanted to write an episode [[ADayInTheLimelight focused on Agent Maine]] during the years of Project Freelancer, and have it [[StartOfDarkness depict Sigma]] manipulating him into becoming [[TheBrute the Meta]] - but from ''[[AnotherSideAnotherStory his]]'' perspective.
*** There was originally going to be a multi-part story about 479er written by Kerry Shawcross. It didn't make the cut due to time constraints.
*** Relatedly, Shannon [=McCormick=] apparently told Miles Luna about the idea of a "Freelancer Ladies' Night Out"-style episode that would've focused on 479er and Carolina hanging out at Errera. Unfortunately, the animation department was too busy with the Merc Trilogy at the time to work on it. However, it ''did'' help inspire the idea for Shannon's two Freelancer episodes - "The Triplets" and "'The 'Mission'."
*** Gray Haddock had an idea for a genuinely scary horror story centered around Charon Industries. As Haddock ran Rooster Teeth's entire animation department at the time, he was too busy to be able to work on it.
*** Kyle Taylor wanted to make a story focused on York, taking place between him leaving Project Freelancer and meeting up with Tex in ''Out of Mind''.
** Season 14 was "a sort of audition process" for who would be the showrunner next season. It could've been any of the writers and directors who contributed, or maybe some of the aforementioned people who didn't get to, but they ultimately chose Joe Nicolosi.
** Season 15 Episode 5 had some cut jokes:
*** To explain why everyone is still wearing their armor, Caboose would've found a nail gun while their bases were being built, and everyone would've had a bunch of nails on them. Having so many tiny nails on every character was too difficult to animate, though.
*** The original idea for the episode was that none of them could get along, so they would each live on a different part of the moon and essentially have their own countries. Once a month, they would all come together for a UN-style meeting. The whole concept ended up being too convoluted, so it had to be scrapped.
** According to a [=post-Season=] 15 Reddit [=AMA=] with Joe Nicolosi, the Blues and Reds' original EvilPlan was to cause a massive explosion on the far side of Earth's Moon and [[ColonyDrop force it to crash into the planet below]], with Jax's "Moon Doom" script meant to serve as {{Foreshadowing}}.
** Season 16 Episode 10 had two jokes cut when there was a decision to make a slideshow instead of video: Caboose would have been the echo that responds to his past self in the cave scene in Season 11, and when Caboose was time-skipping while on fire, he would've inspired Moses by igniting a bush. WordOfGod is that the former is still canon, [[RuleOfFunny just because it's funny.]]
** According to Jason Weight, ''Singularity'' initially had two other possible titles: ''Everwhen'' and ''The Firewall Paradox''. The former eventually became the title of the season's second episode.
*** Speaking of ''Singularity'', Lee Eddy was originally not going to be cast as Chrovos for the season. However, Jason Weight was so impressed by Eddy's voice acting when he was visiting the ''Camp Camp'' panel at RTX 2018 that he decided to rewrite Chrovos as a woman for ''Singularity'' just to have Eddy voice her.
*** While filming ''Singularity'' and having several events taking place during the earliest seasons, Burnie Burns, Jason Weight, and Miles Luna discussed if they should have Past Caboose [[EarlyInstallmentWeirdness sound more like he did during the first season]] or just stick with the current voice. They eventually kept it the same since Sarge had a similar case where the voice sounded nothing like he does in the present, but they hadn't already changed it for the Blood Gulch Prequel Trilogy episodes in Season 14 and they decided to keep it the same for Caboose so it wouldn't be distracting.
*** Since there's countless scenes in ''Singularity'' taking place during the events of previous seasons, there was a point where Rooster Teeth considered [[StockFootage re-using old footage from previous seasons]] to make the workload easier. However, aside from a few shots in montages, that didn’t work, and everything had to be re-shot, re-recorded, and [=RT=] even had to get back all of the voice actors that weren’t still on the show. According to RTX 2019, the primary reason why is because of how much graphics quality has evolved over time, so putting together the old ''Halo'' footage with the new would've been very noticeable.
*** [[invoked]] In an interview after the season, Jason Weight claimed that [[spoiler:Simmons' Labyrinth illusion was more or less the same as what was seen in "Theogeny"... except for that Simmons' ''[[AbusiveParents father]]'' was inside of the [=UFO=] attacking Simmons, and it was meant to serve as a Freudian reference to Simmons still feeling like he's in his father's shadow. The higher-ups at [=RT=] vetoed the idea since it could come off as unintentionally [[{{Squick}} incestuous/pedophilic]].]]
*** Weight also stated that the season's final script was the third delivered. The second had a different concept, where Blood Gulch was sort of a containment unit stationed at the beginning of time while Chrovos worked his way into eroding time from the present backwards. He would even release [[https://www.dropbox.com/s/8cu81vbhyxkphb5/S17E01%20v4%20SHORTENED%20VERSION.pdf?dl=0 one earlier draft]] once ''Series/WandaVision'' turned out to go for similar grounds.
*** The aforementioned interview also notes that Miles Luna had toyed with having a scene set directly after Season 13, but Weight felt that it was best to leave that area alone since it had ended on such a perfect note already and so convinced him to let the moment be left alone. Weight also toyed with having the Blood Gulch Crew actually see Epsilon’s final message and Tucker picking them up/explaining Epsilon's nature, but the scene was both too long and not directly involved with the rest of the season's storyline, so Miles Luna instead went with [[spoiler:having Tucker re-live the Battle of Crash Site Bravo]].
*** Finally, [[https://twitter.com/aJasonWeight/status/1203407218378448896 the Cosmic Powers other than Chrovos and Genkins would've had roles in the season.]]
** [[https://twitter.com/AnimatedTorrii/status/1421514851348885514 Season 18 was supposed to still use the original cast alongside new characters, downright opening with Caboose and featuring a fight scene for Tucker.]] ExecutiveMeddling told otherwise. [[https://twitter.com/animatedtorrii/status/1474088690758520855?s=21 Some actors also didn't want to return]].
** On Joshua Kazemi's [[https://roosterteeth.com/g/post/b099592a-624a-4f61-a581-e27a18c5809a post-release episode notes]], he notes the Carolina\One\East fight would have a ''The Matrix''-inspired scene where Tiny would break into a mess hall to announce it to the others, but they deemed the scene unnecessary.
** The overall plot for ''Zero'' and whatever was intended to come of it falls under this [[https://twitter.com/seanhinz/status/1509229023771205645?s=21&t=ysp5ydVVsMXiOTHX8BVsGw following an official statement]] from Sean Hinz (the current co-head of Rooster Teeth's Animation Department) revealing the ''Zero'' plot would not be continued following the season's negative reception.

*** While playable in the first three games, ''VideoGame/Halo4'' and ''VideoGame/Halo5'' lack the ability to play as aliens like the Sangheili/Elites. This prevented aliens from having major roles in the narrative without certain workarounds as seen in Season 13, such as Santa using a ''VideoGame/Halo3'' model and Junior's [[TheCameo cameo]] being made in ''Halo 3''.
*** In ''[[WebAnimation/RedVsBlueTheChorusTrilogy The Chorus Trilogy]]'', made using ''VideoGame/Halo4'', the Federal Army of Chorus all wore Prefect helmets, and most wore Prefect body armor, in particular Dr. Grey. As the Prefect armor was not available in ''VideoGame/Halo5'', Dr. Grey's was changed to the Cypher helmet and Legionnaire body armor.

*** Part of Locus' characterization was his considering himself to be nothing more than a killing machine, even taking the name of his armor as a result, punctuated with the "X" on his helmet reflecting the scar on his face. ''VideoGame/Halo5'' redesigned the Locus helmet, removing the iconic "X" and making it lighter in coloration. InUniverse this [[RuleOfSymbolism helps show]] Locus's HeelFaceTurn and CharacterDevelopment.

*** [[invoked]] In an interview after the season, Jason Weight claimed that [[spoiler:Simmons' [[YourWorstNightmare Labyrinth illusion]] was more or less the same as what was seen in "Theogeny"... except for that Simmons' ''[[AbusiveParents father]]'' was inside of the [=UFO=] attacking Simmons, and it was meant to serve as a Freudian reference to Simmons still feeling like he's in his father's shadow. The higher-ups at [=RT=] vetoed the idea since it could come off as unintentionally [[DudeNotFunny incestuous/pedophilic]].]]

* RelationshipVoiceActor

** The overall plot for ''Zero'' and whatever was intended to come of it falls under this [[https://twitter.com/seanhinz/status/1509229023771205645?s=21&t=ysp5ydVVsMXiOTHX8BVsGw following an official statement]] from Sean Hinz (the current co-head of Rooster Teeth's Animation Department) revealing the ''Zero'' plot would not be continued following the negative reception the season received.

* NamesTheSame: Try not to confuse Sigma with [[VideoGame/MegaManX another]] BaldOfEvil character of the same name. Though it does make a decent comparison, since both are major antagonists and have a very close connection to corruption.
** Agent Zero is not to be mistaken for Agent Zero from the Steve and Carlos series.

* CashCowFranchise: On a lesser level than ''WebAnimation/{{RWBY}}'', given half the assets from the show are technically property of Microsoft's. Still, Rooster Teeth's founders quit their old jobs and managed to live with the cash from T-shirts, posters and [=DVDs=] (not to mention [=PayPal=] and the Sponsor program, now known as RT First), and still bring out merch such as [[EverythingsBetterWithPlushies a Caboose Plushie]].

-->'''Washington''': I'd say that was the '''[[RougeAnglesOfSatin calvary]]'''...(Sic)

** ''Singularity'' confirms that [[spoiler:[=479er=] was the voice of "Recovery/Freelancer Command" heard during ''Recovery One'' and ''Reconstruction'']]. While many had already assumed that this was true, it wasn't until ''Singularity'' that the two characters were confirmed InUniverse to be the same person and not just a case of two different characters with similar-sounding voices.

* WordOfGod: Creator/ShannonMcCormick says [[https://youtu.be/JdTSoUV4BfU?t=1355 in an interview]] that Darryl is African-American.
* WorkingTitle: The first title for spin-off ''Q vs. A'' was Grimmons, but as the producer put it "we don't want to take [[PortmanteauCoupleName that]] from the fans". The trailer announcement still made a FandomNod to that ("Is that what people call us?").

** Miles Luna's favorite characters to write are Wash and Tucker, Joe Nicolosi's favorite character to write is Grif, and Jason Weight's favorite characters to write are Kaikaina/Sister and Donut.

** While Miles Luna was writing "The Not So Good Ol' Days" for ''Singularity'', which had Wash going back in time to try and learn more about Carolina, Jason Weight asked [[StatingTheSimpleSolution "Why doesn't he just ask her in the future where they are friends?"]]. That lead Luna to furiously yell "Goddammit!" at the simple solution he missed. The exchange became a joke (courtesy of Wash in Mile’s place) in the actual episode.

** As noted under ScheduleSlip, ''Zero'' took a whole year to make due to both the transition between production crews and the UsefulNotes/COVID19Pandemic at a certain point forcing everyone to work from home - and both [[https://twitter.com/AnimatedTorrii/status/1421514851348885514 showrunner Torrian Crawford]] and [[https://pbs.twimg.com/media/E7ulNGzWYAAekgQ?format=png&name=900x900 animator Kristina Christofferson]] noted how stressful and unfavorable things were. It also suffered another production delay just as it would be released with Ryan Haywood's RoleEndingMisdemeanor, which required his role to be recast and redubbed. Furthermore, Rooster Teeth itself was hit with multiple high-profile [=PR=] messes during the seasons' production cycle, most notably Joel Heyman being fired for making offensive comments on Twitter and both Burnie Burns and Rebecca Frasier resigning from Rooster Teeth (albeit with both seeming to be on good terms with the company itself, with the door being kept open for them to potentially reprise their roles later on).

* TalkingToHimself: Several times, given that many people play multiple parts.
** Burnie Burns plays Church, Lopez, Vic, and other voices when needed; he also does sound effects with his own voice, such as grenades hissing and ominous wind.
** Matt Hullum plays Doc, Sarge, O'Malley, and Wyoming.
** Nathan Zellner plays The Alien/Crunchbite and Andy.
** Jason Saldaña plays Tucker and Junior.
** Combined to a degree with TalkingToThemSelf when O'Malley possesses a character; whether O'Malley has what could be considered a separate voice from the possessed regular character varies by character/actor.
** The first half of episode 43 is a climactic confrontation that gathers most characters from the series thus far. Of the ten characters who speak in this scene (including O'Malley), Burns (Lopez, Church, Red Zealot) and Hullum (O'Malley, Doc, Sarge, Wyoming) play all but three (those being Simmons, Grif, and Tucker).
** Gray Haddock plays both the cowardly British General Doyle and the menacing, deep-voiced mercenary Locus, who do talk to each other in Episode 16 of Season 12. However, it's confirmed that Haddock has to do their voices separately.
** Creator/ShannonMcCormick, the voice of Washington, has also voiced Lopez Dos.0 and Agent Iowa, who both have had brief interactions with Wash.
** In Season 15, Gus Sorola voices both Simmons and Gene, his counterpart from the Blues and Reds.

* BTeamSequel: ''Red vs. Blue: Zero'' was done primarily by Rooster Teeth employees more associated with Website/ScrewAttack[=/=]''WebAnimation/{{Death Battle}}'' than those associated with Rooster Teeth's own animation division, in particular lead by former animator Torrian Crawford.

* CelebrityVoiceActor: A surprisingly high amount, including Ed Robertson from the Music/BarenakedLadies as Captain Butch Flowers (somewhat fitting given that the Barenaked Ladies' entertainment style is rather similar to Rooster Teeth's), Elijah Wood as Sigma, Creator/AmberBenson as Female!Grif, [[Creator/ProZD Sung-Won Cho]] as King Atlus Arcadium Rex, and Creator/RiccoFajardo as Genkins. According to WordOfGod, it apparently pays to have friends who are friends with celebrities.

* ChronicallyKilledActor: Following the debut of the "Lopez's Technical Guide to Empathy" [=PSA=] at RTX Sydney, Burnie Burns noted that Lopez was "my only character they did not kill yet" (the others are Church, Epsilon, Vic, and possibly Lorenzo; not to mention the Red Zealot and him briefly voicing both Tex and Omega). During RTX 2019, he downright introduced himself in the [=RvB=] panel as "My name is Burnie Burns, and my character [Church] is dead."

** Miles Luna: In all of ''The Chorus Trilogy'' directed, wrote, edited, and voiced Felix (along with unofficially voicing Donut during his first scene in Season 11). In two of the seasons, he's also credited for machinimating, motion capture, compositing, effects, producing, and casting. He's since done additional writing for most of the post-Chorus seasons up to ''Zero.''

** ''Zero'' brings it back, as Torrian Crawford was responsible for the story, co-writing the scripts, directing, animation, editing, and motion capture. ([[https://twitter.com/AnimatedTorrii/status/1339679237024919552 lampshaded in this annoucement]]) He also had a small voice role in the first episode.
* CreatorBreakdown: ''Red vs Blue'' can take a '''lot''' out of its showrunners on the production side of things, and unfortunately gave birth to the company's [[ChristmasRushed crunch culture]] that has permeated it for nearly two decades.

** A more downplayed case is Tucker getting the Designated Marksman Rifle as his weapon during Season 11, as Miles Luna originally wanted all of Blue Team to use the [=DMR=] during that season. However, he later decided to have Caboose and Wash retain their signature weapons. As this left Tucker having the only [=DMR=] on Blue Team, Luna found it to be distracting and regretted the initial choice.

** Another downplayed example, but Burnie Burns said at [=RTX=] 2019 that he greatly regretted jumping into ''Halo 2'' so quickly during Season 3. Burns also clarified that in the series going forward, [=RT=] sees it as important to at least wait until the current season is over before switching over to the next ''Halo'' game. Burnie has also said that the process of transition from ''Combat Evolved'' to ''Halo 2'' was so stressful he got no sleep for nearly three days and fell asleep ''mid conversation'' with someone, making them think he'd had a seizure or died.

** "This One Goes To Eleven" is Miles Luna's favorite episode.
** Burnie Burns has said that Chapter 19 of ''Reconstruction'' is both his favorite episode and what he feels is the best episode that he's ever written for [=RvB=].

** Elijah Wood as the evil, creepy Sigma. Mind you, this isn't [[Film/SinCity the first time]] he's taken up the role of a villain.

** Miles Luna, who played [[NaiveNewcomer Jaune]] [[ButtMonkey Arc]] in ''RWBY'', plays the very much badass Felix. Moreso in Season 12, when he turns out to be one of the bad guys, and a rather AxCrazy and FauxAffablyEvil one at that who puts on the dorky routine to manipulate.

** Monty Oum, who would help add in [=CGI=] animation to the series starting with the season finale of ''Recreation'' and would be brought on as a guest writer & additional voice actor in later seasons.
** Elijah Wood, who would voice the [=A.I.=] fragment Sigma during Season 10.

** Miles Luna, who also co-wrote Season 10, wrote and directed ''The Chorus Trilogy'', and contributed to several episodes of Season 14. Luna would also later both write an episode of ''Singularity'' and co-write another with Jason Weight for that same season.

*** Speaking of ''Singularity'', Lee Eddy was originally not going to be cast as Chrovos for the season. However, Jason Weight was so impressed by Eddy's voice acting when he was visiting the ''Camp Camp'' panel at [=RTX=] 2018 that he decided to rewrite Chrovos as a woman for ''Singularity'' just to have Eddy voice her.
*** While filming ''Singularity'' and having several events taking place during the earliest seasons, Burnie Burns, Jason Weight, and Miles Luna discussed if they should have [=Past!Caboose=] [[EarlyInstallmentWeirdness sound more like he did during the first season]] or just stick with the current voice. They eventually kept it the same since Sarge had a similar case where the voice sounded nothing like he does in the present, but they hadn't already changed it for the Blood Gulch Prequel Trilogy episodes in Season 14 and they decided to keep it the same for Caboose so it wouldn't be distracting.
*** Since there's countless scenes in ''Singularity'' taking place during the events of previous seasons, there was a point where Rooster Teeth considered [[StockFootage re-using old footage from previous seasons]] to make the workload easier. However, aside from a few shots in montages, that didn’t work, and everything had to be re-shot, re-recorded, and [=RT=] even had to get back all of the voice actors that weren’t still on the show. According to [=RTX=] 2019, the primary reason why is because of how much graphics quality has evolved over time, so putting together the old ''Halo'' footage with the new would've been very noticeable.

* WrittenByCastMember: Of the main writers, everyone but Monty Oum and Joshua Kazemi voices a character. Burnie Burns and Matt Hullum have a lot of roles, Miles Luna started with no role in Season 10 but became Felix afterwards, and Joe Nicolosi was Jax Jonez. Season 14 has promoted examples with Shannon [=McCormick=] (Washington, wrote two episodes where he appears as both him and Iowa) and Barbara Dunkelman (Katie Jensen, also voices female Donut in "Head Cannon"), plus several guests -- James Willems as Drag in the two episodes written and voiced by members of Funhaus, the Game Grumps in ''Gray vs. Grey'' (where Miles also co-wrote and appeared), and the creators of ''WebAnimation/DeathBattle'' in the Meta vs. Carolina episode. Season 16's co-writer Jason Weight plays the Orange Knight (who is later revealed to be Lancelot). In Season 17, where Weight was the lead writer, he voices [[spoiler:the Labyrinth's simulacrum of the [[SadisticTeacher sadistic P.E. instructor]] Coach Prestwood]]. In Season 18, Noel Wiggins voices Raymond. ''Family Shatters'' had episodes written by Hannah [=McCarthy=] (Phase) and Jenn Tidwell (East), and Eddy Rivas does the voice of Lopez.

*** When introduced in ''[[Machinima/RedVsBlueTheProjectFreelancerSaga The Freelancer Saga]]'', made using ''VideoGame/Halo3'' and animation, Carolina wore the Rogue helmet and Recon body armor. When the finale of Season 10 shifted to ''VideoGame/Halo4'', Carolina had to have her armor configuration changed due to the Rogue helmet being heavily redesigned between games, instead being given the Recon helmet and Stalker body armor. Any usage of her old configuration was limited to either animation or using ''VideoGame/Halo3'', with the InUniverse justification that she donned armor used by the Space Pirates to infiltrate their numbers. Likewise, when ''[[Machinima/RedVsBlueTheShisnoTrilogy Singularity]]'' touched on where she was at the time of [[Machinima/RedVsBlueTheBloodGulchChronicles The Blood Gulch Chronicles]], it was set in ''VideoGame/Halo2'', which didn't allow armor customization outside of colors, so Carolina wore the standard armor in tan, the InUniverse justification being that she was in hiding and had stored her normal set of armor somewhere else.

*** In ''[[Machinima/RedVsBlueTheChorusTrilogy The Chorus Trilogy]]'', made using ''VideoGame/Halo4'', the Federal Army of Chorus all wore Prefect helmets, and most wore Prefect body armor, in particular Dr. Grey. As the Prefect armor was not available in ''VideoGame/Halo5'', Dr. Grey's was changed to the Cypher helmet and Legionnaire body armor.

*** Speaking of the Season 8 finale, the original script for the episode ended with the ''Halo: Combat Evolved'' engine being used for [[VirtualWorld the "inside" of the Epsilon Unit]] (likely to reflect it serving as a BookEnds for Church's character arc up to that point). This was changed early on due to Bungie approaching Rooster Teeth with early access to ''VideoGame/HaloReach'' and letting them use it for the Epsilon Unit.

** The idea of a journalist character interviewing the Blood Gulch Crew (the character that became Doc - see WhatCouldHaveBeen) [[https://www.confreaksandgeeks.com/red-vs-blue-director-joe-nicolosi/ was recycled for Season 15's protagonist.]]

* VoicesInOneRoom: [[https://www.youtube.com/watch?v=KVIoV7hKaQQ The first episode had this]] aside from Jason recording Tucker's lines over the phone (the original version had Sarge's line spoken by Burnie, and later re-recorded by Matt Hullum), and presumably the Austin-based crew remained as this through the season. The introduction of the Zealots in Season 3 also had everyone recording together (mind you that back then, the "booth" was a closet!). Seasons 15 and 16 had some cases with Carolina and Washington's scenes, though the actors had [[https://www.instagram.com/p/BstgozKFP8g/ to be with their backs to each other so their lines wouldn't be picked up by the other's microphone]], and one episode of season 16 [[https://twitter.com/bexmix/status/993699840776462336 also had Tucker and Sister recording together]].

** A character introduction video that Burnie Burns created in preparation for the pilot episode was based around heavy action and extensive violence. However, Burns ended up taking inspiration from ''Webanimation/HomestarRunner'', ''WebComic/PennyArcade'', and (to a lesser extent) ''Series/MysteryScienceTheater3000'', resulting in the pilot's script being shifted to focus on situational comedy instead.

** The overall plot for ''Zero'' and whatever was intended to come of it falls under this [[https://twitter.com/seanhinz/status/1509229023771205645?s=21&t=ysp5ydVVsMXiOTHX8BVsGw following an official statement]] revealing the ''Zero'' plot would not be continued following the negative reception the season received.
