* 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.]]
** 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.
* BigNameFan: Creator/RoosterTeeth themselves are this to ''{{Franchise/Halo}}''.
* 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) and Elijah Wood as Sigma. According to WordOfGod, apparently it pays to have friends who are friends with celebrities.
* 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 we see inside his locker, inside are some towels, a skateboard featuring the Rooster Teeth emblem, a rubber ducky, and ''pictures of cats!'' Shannon [=McCormick=] had known about the fanon, having discovered it on Tumblr, and specifically campaigned to get the cats included.
* 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.
*** 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.
* {{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 ''{{Halo 3}}'', and the Forge map builder, [[http://www.halopedian.com/Grifball and the rest is history.]]
* FlipFlopOfGod: [[spoiler: Donut was killed by Washington (the "Recreation" DVD commentary confirms this), 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 RoosterTeeth planned this, and were intentionally misleading in that commentary so as to preserve the secret.
* HeyItsThatVoice: While most of the cast is from the Creator/RoosterTeeth office, there are quite a few from outside of it:
** Captain Flowers is voiced by Music/BarenakedLadies lead singer Ed Robertson.
** You'd probably never guess that Washington is [[GetBackers Kuroudo Akabane]].
** Recovery Command as Pilot 479. However, this [[CallForward seems to be intentional]].
** The grunts who argue for a bit and then die in Season 9 are often voiced by WebVideo/{{Smosh}}. They both returned for the trailer for Season 11, albeit as different characters.
** Creator/ElijahWood voices the AI Sigma in Season 10.
** The two GatlingGood mooks are voiced by [[Creator/AchievementHunter Michael Jones]] (of ''Rage Quit'') and [[WebAnimation/{{RWBY}} Lindsay Tuggey]] (his [[OfficialCouple then-girlfriend, now wife]]), Rooster Teeth employees.
*** Lindsay taking a larger role as the leader of the rebels on Chorus.
** Private Jones (from [=S6E3=]) is voiced by [[WebVideo/TheSlowMoGuys Gavin Free]], a Rooster Teeth employee and one of the regular Achievement Hunters.
** Other people from around Rooster Teeth are also littered around. Ray, Kerry, Ryan, etc. all appear as characters with only a line or two.
** The Season 12 lieutenants are voiced by Brandon, Barbara, Kerry and Ryan, and Ray and Michael appear as soldiers helping edit training videos.
* {{Jossed}}: For a while, fans had speculated that Sarge and (after Recreation) Tucker might be able to match [[spoiler: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 [[EvilAllAlong one of the bad guys.]] ]]
* ProductionNickname: Creator/MontyOum, one of the animators, simply refers to the "Mysterious Blue Guy" [[spoiler:AKA Butch Flowers/Agent Florida]] as "Blue".
** The only known female in the Insurrection is called "Girlie" by the cast and crew.
* PromotedFanboy: Gavin Free was originally just a fan of series from the beginning, but took over from Burnie Burns as director for ''Relocation'' (the miniseries between Seasons 6 & 7), as well as for all of Season 7 itself.
** 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.
* RelationshipVoiceActor: Just once, but Michael Jones and Lindsay Tuggey are an OfficialCouple in reality, and were paired as the Chain Guy and Chain Girl.
* 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).
* ThrowItIn: Many lines, including one notable case 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.
* WhatCouldHaveBeen: According to WordOfGod, there was originally a concept in which the characters, in preparation for battle, would call out [[InTheNameOfTheMoon "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 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 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]].
