* CelebrityVoiceActor: A surprising amount including Ed Robertson and Elijah Wood.
* 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.]]
** [[spoiler: Felix from Season 11 was named "Sunkist Mcscouty" or "Pumpkin Patrol" due to his Scout helmet and orange striped armour.]]
* 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.
* 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.
* 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.
