* BadassDecay: 'VHS Transfer Memory Lane' reveals amongst other things that Weigel was not only once confident and competent as a police officer, but also smart and even had Dangle of all people attracted to her. So, what happened? [[spoiler: A house fire that occured while the team was on the scene caused a chain reaction and started/created the Reno officers we know today. In Trudy's case, she was clinically dead for 2 minutes but came back and the damage to her brain from the smoke inhalation created the Weigel we all know in the series.]] She briefly recovers this in one episode but it doesn't stick.
* CrackPairing: Jones and Garcia. The black Jones and hispanic Garcia are partners when out on patrol, although Garcia is openly racist (he's on a friendly FirstNameBasis with the local Klansmen). In spite of this, the two are halfway competent as partners and have their own RunningGag of extended chase scenes throughout the show.
** Weigel and Williams. Despite Weigel also being racist (though she blames the racial tension on the squad on Garcia), Williams is probably her closest friend at work. The season 6 finale even has them posing as a lesbian couple.
* EnsembleDarkhorse: By definition, Terry (Creator/NickSwardson), the [[CampGay flamboyantly-homosexual]] (to the point that even [[ButNotTooGay Dangle]] is a little uncomfortable around him) street prostitute. The character appeared in 27 episodes (out of a total 88), and was easily the most popular recurring character not in the main cast. He even got screen time in the movie.
* HollywoodHomely: Deputy Trudy Weigel. She's supposed to be ''extremely'' repulsive. The stings involving her playing a prostitute or a stripper never work.
--> '''Garcia:''' "She's a 'triple-bagger'. One bag over her head, one over mine, and one extra for any unlucky bastard that might accidentally walk by."
* MagnificentBastard: Usually Dangle, occasionally everyone on the force, but the best example being "Spanish Mike" Alvarez.
* RetroactiveRecognition: Subverted with Niecy Nash, who hosted the Style Network's "Clean House" for seven seasons; she was the only one to have a steady gig simultaneously with Reno 911!. Her hosting outlasted her role on "Reno" by one season. She also spent a season on DancingWithTheStars.
** Carlos Alazraqui voiced Rocko on the 1990's Nickelodeon cartoon ''RockosModernLife''. Of course, the two roles are completely different.
** Wendi [=McLendon=]-Covey had a major supporting role in "Bridesmaids".
** Nick Swardson went on to have mainstream success as a comedian and a film actor, an interesting note since he was not in the main cast.
** Cedric Yarbrough had a bit part in ''Film/BlackDynamite'' as the [[MeaningfulName aptly named pimp Chocolate Giddy-Up.]]
** Andrew later became the dean at [[{{Community}} Greendale Community College.]]
** The officers once arrest a Japanese suspect and bring in [[Series/{{Heroes}} Hiro Nakamura]] to translate.
* TheScrappy: Declan and Rizzo.
** ReplacementScrappy: Both these characters were introduced right after the deaths of Johnson, Garcia, and Kimball.
** The latter has the ''potential'' of being [[RescuedFromTheScrappyHeap rescued from the heap]].
* WhatDoYouMeanItsNotSymbolic: The Police-Tek 2000 "Lazarus" Bicycle Lock.
