* ActorAllusion:
** The "Off The Charts" PSA displays pictures and bios of the [[InformedAttribute "manliest"]] members of the Rooster Teeth community, including actual Rooster Teeth team member Gus Sorola. Sarge questions whether Gus should even be in the "manly" montage at all, to which Simmons (voiced by Gus) hurriedly rushes to assert that Gus is indeed very manly, adding [[MindScrew an even greater level of metafiction]] to [[AnimatedActors the already very meta PSAs.]]
** This is not the only time [[Creator/ElijahWood Elijah Wood]] has played a [[WesternAnimation/TronUprising Computer Program]]. This is, however, the first time playing an evil computer program. (The colors even fit.)
** In Seasons 1 and 14, Grif bugs Simmons about going to the Vegas Quadrant, which Simmons is inexplicably and unreasonably pissed about. In a popular Rooster Teeth Animated Adventure, Gus is inexplicably and unreasonably pissed about Burnie talking about going to Las Vegas. It's later revealed that Gus was just too tired to go to Vegas at the time.
--->'''Gus''': I'm not going to Vegas, don't talk about Vegas!
--->'''Simmons''': I'm not going to the fucking Quadrant, don't talk about the Quadrant!
** A more subtle one in the Point/Counterpoint PSA on tattoos. Church (Burnie) argues against getting tattoos while Grif (Geoff) argues for tattoos. In real life Burnie has no tattoos while Geoff is covered with them.
** In Season 11, Grif's teleport cubes get compared to Pokeballs from ''Franchise/{{Pokemon}}''. Grif's hostile response mirrors Geoff's attitude towards the series whenever it's brought up.
** As [=VIC=] reveals in "Red vs. Blue: The Musical", Agent Florida[[note]]who is voiced by [[Music/BarenakedLadies Ed Robertson]], if you recall[[/note]] (who downloaded over 5000 songs onto his hard drive) "was ''really'' big into Music/BarenakedLadies".
** In Season 15, Sister complains that running so many conventions and managing merchandise sales is a lot of hard work. Her voice actress, Becca Frasier, is responsible for managing the RT store and organising RTX.
** Sort-of: During Season 15, it's revealed that the Reds and Blues decided to take some R&R following Chorus. When Season 15 started airing, Geoff was on sabbatical. Adding on to that, [[spoiler:Grif refuses to get involved with the mission of rescuing Church, opting to stay behind on the moon]].
** During their time off, Tucker decided to form a band. Jason Saldaña is the singer and lead guitarist of his own band.
** When Jax asks if he's ever considered showbusiness, Sarge says that he imagines himself playing the thirty-something CEO of a startup internet company, a perfect description of Matt Hullum.
* BigNameFan: Creator/RoosterTeeth themselves are this to ''{{Franchise/Halo}}''.
* {{Blooper}}: This line in the penultimate episode of ''Revelation''. (It's not clear if either Creator/ShannonMcCormick flubbed the line or there was a typo in the script.)
-->'''Washington''': I'd say that was the '''[[RougeAnglesOfSatin calvary]]'''...([[YouMakeMeSic Sic]])
* CelebrityVoiceActor: A surprising 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, and Creator/AmberBenson as female!Grif. According to WordOfGod, apparently it pays to have friends who are friends with celebrities.
* {{Defictionalization}}: In Episode 59 of the Blood Gulch Chronicles, while he, Simmons, and Donut are treating Grif like "one of those ducks at the shooting gallery," Sarge declares that "this is the best game since Grifball!" Then came ''VideoGame/{{Halo 3}}'', and the Forge map builder, [[http://www.halopedian.com/Grifball and the rest is history.]]
* FandomNod:
** A popular fanon of Wash (especially on Tumblr) is "Cat Lady Wash" with fans giving him a cat (usually named Hartford, but this can vary). In Season 10 Episode 14 when we see inside his locker, inside are some towels, a skateboard featuring the Rooster Teeth emblem, a rubber ducky, and ''pictures of cats!'' Creator/ShannonMcCormick had known about the fanon, having discovered it on Tumblr, and specifically campaigned to get the cats included.
** On a similar note, the credits for Rooster Teeth Animation productions say "Wash's Cats: Ari and Skyler" under Security.
* FanNickname:
** "Blood Gulch Crew" for the Reds and Blues that originated from Blood Gulch's team.
** The Mysterious Blue Guy was the most widely accepted nickname for the [[ExactlyWhatItSaysOnTheTin blue-armoured Freelancer of unknown identity]] in the prequel sections, [[spoiler: who turns out to be Agent Florida, better known as Captain Flowers.]]
** All the Insurrectionists have a couple, considering that they have NoNameGiven status.
*** The Insurrectionist Flame Soldier is often called "Sharkface", due to his helmet. Gained [[AscendedFanon official status]] in Season 13.
*** Girlie has many, including "Heartbreaker" and "Hot Lips", both due to her lipmark insignia.
*** Pillman is the most common for the Insurrectionist Leader, due to the insignia on his ODST armor.
** Felix from Season 11 was named "Sunkist Mcscouty" or "Pumpkin Patrol" due to his Scout helmet and orange striped armour. After his name was revealed, "Felix [=McScouty=]" is the generally agreed upon nickname.
** After her mention in the preview synopsis for Season 15 but before her name was revealed, fans were taken to referring to Dylan Andrews as [[ShapedLikeItself Reporter Lady]].
** [[spoiler: Spencer Porkinsenson]] is known by some as "Unicorn" due to his FOTUS helmet. After episode 3, "Goodbye" also started to pick up steam. More formally, he tended to be called "FOTUS Soldier" on wikis before his real name was revealed.
* FlipFlopOfGod:
** [[spoiler: Donut was killed by Washington]] (the "Recreation" DVD commentary confirms this), [[spoiler:then he revives in the sponsors-only ending of Chapter 13 of "Revelation".]] With some {{Retcon}} thrown in as well, since [[spoiler: Donut was not really dead but in Recovery Mode all along]]. It's possible Creator/RoosterTeeth planned this, and were intentionally misleading in that commentary so as to preserve the secret.
** Both the show and Rooster Teeth can't seem to decide whether or not [[spoiler:Alpha-Church and Epsilon-Church]] are the same character due to [[spoiler:Epsilon being created from Alpha's memories and essentially being a back up in some respects]]. One example is in the second episode of season 13, [[spoiler:Epsilon]] asks "In all the years we spent in the canyon, when the hell did [Tucker] learn to dance?" ...Even though by the time [[spoiler:Epsilon]] met Tucker, the Blood Gulch Chronicles were long over. The current stance is that [[spoiler:Epsilon is not Church, who died in season 6]], but whether or not it sticks has yet to be seen. Amusingly, in "The Complete Unabridged Story of Red vs Blue Abridged", this is even lampshaded by the Narrator.
--->'''Narrator:''' [[SarcasmMode Because that's not confusing at all]]!
* HilariousOuttakes:
** There's an audio clip of "Gavino" reading The Director's letter from the Reconstruction Trailer, before Burnie interrupts, clarifying that he didn't want him to be "The Director for the season" he wanted him to "direct the season".
--->'''Gavin''': "Oh... ''Oh''. I get it. My- So I should just-"
--->'''Burnie''': "Get the fuck out of the booth, okay?"
** In another direction, the ''[=RvB=]'' franchise getting nods in the various ''Halo'' titles, the biggest being the [[http://youtu.be/waL8K2SGR1M 'Password Forgetting Marine']] EasterEgg in ''Halo 3'' which features [=RvB=] voice actors, though they are not officially their characters, but are pretty clear who they are. The voices and dialog depend on the difficulty level:
*** Normal: Tucker and Doc.
*** Heroic: Simmons and Grif.
*** Legendary: Church and Caboose.
** Here's a list of diferent season's [[https://www.youtube.com/playlist?list=PLCx_OJK3bFEVsBZlCw6zM2xKU2mjAYmeh Outtakes]]. Remember to breath.
* 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. we all met in ''Recreation'' [[spoiler:wasn't actually Agent Connecticut has been tossed around ever since Washington revealed that C.T. was a girl]].
** Fans also successfully called [[spoiler: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 [[spoiler:Flowers]] were correct, though fewer also guessed he was also [[spoiler:Agent Florida]].
** Early in Season 15, a vast majority of people were assuming that [[spoiler: the Reds and Blues we saw were fakes. They were correct. Dylan even deduced this through the same reasoning as the viewers did (Sarge doesn't have his shotgun, Tucker has a sniper rifle, etc).]]
* InMemoriam: Season 11, Episode 2 was dedicated to David Dreger, a former contributor to Achievement Hunter who was found dead after an extended disappearance.
* {{Jossed}}: For a while, fans had speculated that Sarge and (after Recreation) Tucker might be able to match Tex in terms of combat skill. [[spoiler:Then she returns in Episode 10 of Revelation and utterly curbstomps the both of them without taking a hit or breaking a sweat]]. Episode 19 of Revelation further implies that [[spoiler:Sarge's early takedown of Tex back in Season 1 was a result of WorfHadTheFlu]].
* 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 [[spoiler:have a very close connection to corruption]].
* PlayingAgainstType
** 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.
** [[TeamDad North Dakota]] is a fairly serious guy. His VA is a professional comedian.
** Miles Luna, who played [[NaiveNewcomer Jaune]] [[ButtMonkey Arc]] in RWBY, plays the very much badass Felix. [[spoiler: Moreso in Season 12, when he turns out to be one of the bad guys, and a rather AxeCrazy and FauxAffablyEvil one at that who puts on the adorkable routine to manipulate.]]
** Also from RWBY, Lindsay Jones who played [[PerkyGoth Ruby]] [[{{Adorkable}} Rose]], plays the very serious [[DaChief Vanessa]] [[ReasonableAuthorityFigure Kimball]].
** Yet again with RWBY, Arryn Zech is known for playing the stoic and reserved Blake. Here she voices [[GenkiGirl Emily]] [[MadScientist Gray]], who's a bit... crazier with a double dose of psychotic.
* ProductionNickname: Creator/MontyOum, one of the Freelancer animators, simply referred to the "Mysterious Blue Guy" [[spoiler:AKA Butch Flowers/Agent Florida]] as "Blue". Likewise,the only known female in the Insurrection is called "Girlie" by the cast and crew.
* PromotedFanboy: Many of the people who've worked on the show in more recent years started out as fans, including but not limited to:
** GavinFree, who directed Recreation and the Recolated miniseries.
** Eddy Rivas, who co-wrote Season 10.
** Miles Luna, who also co-wrote Season 10, wrote and directed The Chorus Trilogy, and contributed to several episodes of Season 14.
** Jordan Cwierz, who wrote the Season 14 prequels to The Blood Gulch Chronicles.
** Barbara Dunkelman, who wrote the Season 14 episode Head Cannon.
** Joe Nicolosi, who wrote, directed, and animated the Season 14 episode The Brick Gulch Chronicles, and is currently writing and directing Season 15.
* RealitySubtext:
** Dylan Andrews is sometimes written as if she were a fan of the show. She thinks there's still an interesting story to be found in the Reds and Blues, and she wants to see how it ends. She also expresses great interest in finding out what happened aboard the Staff of Charon towards the end of the Chorus war.
** Conversely, Carlos is written like someone who dislikes the show. He thinks the Reds and Blues are boring and lack depth. He would prefer it if Dylan reported on a group of [[WebAnimation/{{RWBY}} "monster-fighting sexy teenagers"]].[[note]]Not everyone who likes RWBY dislikes Red vs. Blue, but RWBY has become the more popular of the two.[[/note]] He also finds the events that happened in Blood Gulch too crazy to take seriously.
* RefittedForSequel: The idea of a journalist character interviewing the Blood Gulch Crew (The character that became Doc- see WhatCouldHaveBeen) was recycled for Season 15's protagonist. [[note]]https://www.confreaksandgeeks.com/red-vs-blue-director-joe-nicolosi/.[[/note]]
* RelationshipVoiceActor
** In Season 10, Michael Jones and Lindsay Jones (nee Tuggey) are an OfficialCouple in reality, and were paired as the Chain Guy and Chain Girl.
** In Season 12, Burnie's son was brought in to voice Theta.
* RunningTheAsylum: Miles Luna was given control of the series for Seasons 11 to 14, though the original creators did help him get his bearings at first. Now that Joe Nicolosi is running the show and Miles is helping him, however, this is in full effect. Joe even said he felt like he was writing fan fiction in an interview.
* SerendipityWritesThePlot:
** During Tex's flashback cameo in Season 15, she is using the voice filter (and thus is once again voiced by Burnie Burns), owing to Creator/KathleenZuelch's break with Creator/RoosterTeeth.
** A subtle case: The [[ArtEvolution redesign]] of [[spoiler: the locus helmet]] in ''Halo 5'' means that [[spoiler: Locus no longer sports the iconic "X"-mark on his helmet. Both the lack of the "X" and the use of lighter colors on the helmet [[RuleOfSymbolism help show]] Locus's HeelFaceTurn and CharacterDevelopment]].
* ShrugOfGod: The Ultimate Fan Guide answers a lot of long-standing fan questions, but it says that Church's time travel shenanigans in Season 3 are subject to "conflicting reports", which seems to be the writers' way of saying that they don't know if it really happened either.
* TalkingToHimself: Several times, given that people play multiple parts.
** Burnie Burns plays Church, Lopez, Vic, and other voices when needed; he also does foley and sound effects with his own voice, such as grenades hissing and ominous wind.
** Matt Hullum plays Doc, Sarge, and Wyoming.
** Nathan Zellner plays Crunchbite and Andy.
** Jason Saldana 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 Gray does 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.
* TheOtherDarrin: John Reed does not voice the Director during his cameo in Season 15, and it is currently unknown who did the voice work.
* ThrowItIn:
** Many lines, including one notable case in season 3 where Donut in the script was supposed to just scream once, but the actor decided that instead he'd run around babbling incoherently while the other characters delivered their lines. Most of the time the cast agrees that what was improvised was better than the actual script.
** While relatively common after 12 years of the voice actors knowing their characters (one running joke is 'You think we actually write for Caboose?'), the reigning champion is reportedly Matt Hullum's work as Sarge. By all reports, sessions with him last far longer than anything scripted as he rambles on in every different direction, which is fully in Sarge's character.
--->Great Monopoly's Tophat!
** Overlapping with WhatCouldHaveBeen; Joe Nicolosi was originally going to voice Lorenzo, and Burnie provided him with reference audio to help him with the role. However, Joe thought Burnie's Italian was so hilariously bad that he just decided to use the temp audio instead.
* WhatCouldHaveBeen:
** 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 comments, a la JustForFun/StatlerAndWaldorf.
** 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 hitting too close to home for the real wars happening at the time.
** Doing the AnimatedAdaptation was an ambitious idea, but the crew just didn't have the money and time for it. They also didn't like the fact that someone else had to do the animation, so they couldn't do it in-house.
** The commentary track on the ''Revelation'' DVD suggests that Grif [[spoiler:[[YouKillItYouBoughtIt was originally going to take up the Meta's brute shot]]]] as his WeaponOfChoice (he's noticeably the only member of the main cast not to have one). Ultimately they decided not to go with this idea, however. [[spoiler:Until he decides to help save Carolina and Epsilon in Episodes 20 and 21 of Season 10.]] As it is, the weapon became unavailable in the Halo 4 engine, meaning it could not be used for Seasons 11 & 12, and was [[spoiler:explained that it was confiscated by the UNSC between 10 & 11]].
** 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]].
** There were plans to give the Red's Warthog be a character in the same vein of the Blue's with Sheila in the Scorpion Tank. The idea was to have the Warthog have a similar personality to Speed Buggy.
** 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 sweet but naive girl-next-door type, but that was before they interviewed Rebecca Frasier. The writers played a joke on Rebecca 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.
** Early plans for Episode 8 of Season 13 were to [[spoiler: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]].
** Early in the development of Season 11, [[spoiler: 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.]]
** In an interview on Afterbuzz TV, Miles revealed that an early plan was for [[spoiler:Kimball to lose it when Felix's betrayal is revealed and shoot Doyle, then be shot down herself]].
** Originally, Sarge's animosity towards Grif would have ended 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.
** An early idea for the "Mysterious Blue Freelancer" was that it was [[spoiler: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 [[spoiler:red helmet]], allowing them to reveal his voice. They then decided that making it [[spoiler:Flowers]] would be better.[[note]]As per [=RvB=] at RTX 2016[[/note]]
** 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.[[note]]In other words, because Kerry was too lazy to finish it on time.[[/note]]
*** 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 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 Gray runs the animation department, 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.
** ''Revelation'' was originally going to be titled ''Resolution''- Burnie 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).
** 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 this 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.
*** The first draft of the script (which was written around the time of the 2016 election) had everyone accidentally voting for an orange pile of vomit to be their president. The punchline would've been "At least you didn't win the popular vote!" This was replaced by the Malarkey joke, because it was funnier and less political.
* WordOfGay: While "The 'Mission'" explicitly reveals Ohio to be gay, it's more ambiguous about Sherry. Creator/ShannonMcCormick, the episode's writer, confirms it, however.
