- Actor Allusion:
- The Fearless Ferret episode was a cross-spoof of the 60s Batman series and Batman Beyond. Will Friedle was the voice actor for Beyond's Terry McGinnis, while Timothy North's voice actor was Adam West, who played Batman in the 1960's TV show.
- This isn't the first time Tahj Mowry's played a kid genius on a Disney show.
- Also, Chris McDonald (Hego) voiced Superman on an episode of Batman Beyond with Will Friedle.
- In "And The Molerat Will Be CGI", Monique, played by Raven-Symone, gossips at a table with Kim, Bonnie and teen idol actress Heather, played by Anneliese Van Der Pol, who plays Chelsea Daniels in That's So Raven. Monique and Heather can really relate to each other.
- During a scene in The Cupid Effect, while ad-libbing a love note to Wade's Mom, Señor Senior Sr. (Ricardo Montalban) casually tosses in a line about chasing the wealth of the world " 'round perdition's flame".
- This wasn't the first time Tom Kane voiced a monkey.
- Kim's lab partner, Justine Flanner, is voiced by Mayim Bialik, who holds a degree in neuroscience.
- Ascended Fanon: Quite a bit of fanon, most obviously the names of Kim's parents.
- Contest Winner Cameo: Josh and Katlyn in Season 4.
- The Danza: Tara, voiced by Tara Strong.
- Defictionalization: Purely unintentional...probably, but there has been a great deal of positive response to Taco Bell's new Beefy Nacho Burrito because after ten years they finally caved and made a real life Naco.
- The Grilled Stuffed Nacho introduced in December 2013 is perhaps even closer to the Naco.
- Dueling Shows: Totally Spies! was another "secret agent high-school kid" show. It predated Kim Possible (which began in 2002, while Totally Spies began in 2001).
- Executive Meddling: Both Good and Bad:
- They requested an animal sidekick. We got Rufus.
- In the episode "Bad Boy", Standards and Practices wouldn't allow the writers to show Drakken making coffee. They suggested chocolate milk instead, and the writers turned that into "Coco Moo", resulting in one of the series' funnier gags. (The rumor that "Coco Moo" itself resulted from S&P forbidding the phrase "chocolate milk" is unfounded, as Drakken actually does use that phrase in the episode.)
- The "good eating" episode, mandated by exec, but what we got was....shudder
- The original plan to make "Rappin' Drakken" a Villain Episode was vetoed.
- Requested that the hats in "Showdown at the Crooked D" be called "Silly Hats" rather than "Stupid Hats". They even lampshaded it.
Drakken: The Silly Hat!
Shego: Not the name I would have chosen...
- Fake Brit: British-Israeli Brian George as Scottish Duff Killigan (Brian George is actually English by birth).
- I Knew It: Early fanfictions were writing Shego as having a brother named "Hego" who is a superhero long before the actual character appeared. Fans didn't anticipate her having multiple brothers though, and especially not her being an ex-hero.
- Irony as She Is Cast: "Hidden Talent" reveals Kim cannot sing high notes. In fact she is truly atrocious at it. Christy Carson Romano, her voice actress, is in fact an accomplished singer as she demonstrates at the end of the episode.
- Keep Circulating the Tapes: The show has never been fully released on DVD. As of October 2010, Disney has released the first two seasons in the US, but as a Disney Movie Club exclusive.
- Non-Singing Voice: The Oh Boyz singing voices are not the same as their acting voices.
- The Other Darrin: Shaun Fleming voiced the Tweebs for the first three seasons all the way to So The Drama. When the series was renewed for a fourth season, Fleming was going through too much puberty to reprise. Spencer Fox was chosen to replace him.
- Breckin Meyer who voiced Josh Mankey in the pilot episode, was replaced by A.J. Trauth in all other appearances for unknown reasons.
- Shrug of God: Taken by Bob Schooley after the series' end when it comes to some (not all) questions.
- Talking to Himself: Drakken and Motor Ed share a voice actor, and appeared together in one episode. Seriously.
- Throw It In:
- Shego's personality. Originally she wasn't intended to be a Deadpan Snarker who enjoyed needling her boss more than listening to him, but Nicole Sullivan's voice acting led the writers to play to her ability for that.
- Motor Ed was created because John DiMaggio was goofing around in the break room and made up the voice for a laugh.
- What Could Have Been:
- Word of God:
- The Creators Bob Schooley and Mark McCorkle have stated Kim Possible and Ron Stoppable were meant to be together from the start of the series and will be together forever. Also, despite the show's Non-Lethal Warfare, the aliens in the Grand Finale were killed, Drakken and Shego are a couple and still evil (just "a more annoying kind of evil") and don't worry about what they've said.
- Warmonga and Warhok are married, at least according to Steve Loter.
- Writer Revolt: Compelled to make a episode about dietary health, the story sees Ron hulk out due to a vat of stuff and a lot of junk food in a parody of Supersize Me. He delivers the ''wrong'' moral (don't mess with dangerous chemicals) to the camera while a growing crowd behind him wonder who he's talking to.
