----
* AbsenteeActor:
** Pleakley appeared in every episode except for "Morpholomew", the {{crossover}} episode with ''WesternAnimation/AmericanDragonJakeLong''.
** Gantu was absent for ten episodes, five for each season.
*** Reuben, who only appears in episodes that Gantu appears in, was absent for fourteen episodes (eight in season one, six in season two). In addition, he appears but does not speak in "Swapper".
** Nani, who had a reduced role anyway, was absent for twenty-two episodes (fourteen in season one, eight in season two).
* ActorAllusion: In one episode Pleakley claims he and Jumba are "Canadians from Canadia." Kevin [=McDonald=] is Canadian.
* BonusEpisode: "Link" was this for the DVD release of ''WesternAnimation/LeroyAndStitch'', and it aired as the last episode of ''The Series'' a month later.
* CreatorsFavoriteEpisode: Jess Winfield stated on his TV Tome Q&A thread (partial fan archive [[http://lilo-andstitch.tripod.com/tvtome/page03.html here]]) that his favorite episode was "Yin-Yang", saying that the episode's experiments, story, and theme worked well together. "Angel" and "Bonnie & Clyde" were also his other favorites. However, he stated this in December 2004, during the early days of the second season, so it's unknown if his opinions have changed afterwards.
* CrossDressingVoice:
** Creator/TressMacNeille, Creator/TaraStrong, Dionne Quan, Creator/NancyCartwright and Creator/FrankWelker for several experiments.
** ''Series/TheKidsInTheHall'' cast members Scott Thompson and Bruce [=McCulloch=] voice Pleakley's mother and sister Pixley, respectively.
* ExecutiveMeddling:
** The executives did not like [[LoveInterest Angel]] and didn't want her to appear again. After finding out about [[BreakoutCharacter her popularity among fans]], they relented, but only for [[GrandFinale the last episode]].
** On the other hand, Keoni Jameson was mandated by Disney execs as an [[AudienceSurrogate audience avatar]]. [[TheScrappy The fans]] [[CreatorsPest and the writers hated him for it.]]
** The show was originally conceived as an action-adventure series with a similarly somber tone as the film, but Creator/DisneyChannel wanted something LighterAndSofter.
* FanNickname:
** 627 is given the name "Evile" by fans and [[TheWikiRule wikis]] due to "evil" being [[PokemonSpeak the only word he said]], [[Anime/{{Stitch}} at least initially]]. That being said, he was never named by anyone in the franchise proper.
** On the flip side, Leroy from ''WesternAnimation/LeroyAndStitch'' is also called Experiment 629 by fans and wikis. Although some commercials that aired before his debut and some Japanese merchandise number him 628, there was already an Experiment 628 as seen in pod form at the end of 627's episode. 628 was never activated, and Leroy was never officially numbered by Jumba. (Jumba tried to number him 627, but Gantu reminded him that he already made Experiment 627.)
* MissingEpisode: The {{crossover}} episode with ''WesternAnimation/{{Recess}}'' never aired on Disney Channel, possibly because the network was worried that the kids that were into ''Lilo & Stitch'' would have no idea what ''Recess'' is.
* NoExportForYou[=/=]KeepCirculatingTheTapes:
** ''The Series'' has been fully released on DVD, but only in Japan. Some episodes were also released on DVD in other regions, but not in full, and there has never been a Region 1 (United States and Canada) DVD release of ''The Series''. In those two countries, "Mr. Stenchy" and "Clip" were released on a DVD game called ''Lilo & Stitch's Island of Adventures'', "Slushy" and "Poxy" were released on separate UsefulNotes/GameBoyAdvance Video cartridges,[[note]]bundled with episodes of ''WesternAnimation/KimPossible'' and--alongside "Poxy" only--''WesternAnimation/BrandyAndMrWhiskers''[[/note]] and "Link" is a bonus feature on the ''WesternAnimation/LeroyAndStitch'' DVD.
** On the digital distribution and streaming front, all four ''Disney/LiloAndStitch'' [[Disney/LiloAndStitch2StitchHasAGlitch films]] are on services such as [=iTunes=], Amazon, and Creator/{{Netflix}}, but ''The Series'' has never been made legally available for either home or digital video in its entirety in the West. There will be a lot of missing context if one were to watch both ''WesternAnimation/StitchTheMovie'' and ''Leroy & Stitch'' without ever having seen ''The Series''. The show is legally available on digital services in some countries and in English, but only in countries outside of the Anglosphere.
*** Going even further, ''The Series'' was produced and broadcast in UsefulNotes/HighDefinition at 16:9 widescreen, but most uploads--legal and illegal--are only in standard-def at 4:3 full-screen.
* TalkingToHimself: [[AllStarCast Lots of them]], including Creator/JeffBennett, Creator/NancyCartwright, Music/GreyDeLisle, Creator/TressMacNeille, Creator/RobPaulsen, Creator/ChrisSanders, Creator/TaraStrong and Creator/FrankWelker.
** [[Creator/DaveighChase Lilo and Victoria]], though only in the latter's first appearance.
** Both Mrs. Edmonds and Aunt Stacy are voiced by Creator/AprilWinchell.
* TechnologyMarchesOn: [=VCRs=] and videocassettes were shown or referenced a few times in the show. Those things were already in decline by the time ''The Series'' debuted and would become completely obsolete in just a few years.[[note]]In fact, the year the show debuted (2003), DVD rentals exceeded VHS rentals in the United States for the first time. ''Leroy & Stitch'' (2006) even holds the distinction of being the only ''Lilo & Stitch'' film to have never seen a VHS release.[[/note]]
* TheOtherDarrin:
** In one episode, Creator/KevinMichaelRichardson voiced Cobra Bubbles. Creator/VingRhames does voice the character though, but it's unknown which episodes.
** Creator/DeeBradleyBaker replaced Jason Scott Lee as the voice of David in ''The Series''.
** In her first appearance, Victoria is voiced by Creator/DaveighChase, which lead to TalkingToHerself with Lilo, and in her second appearance, Alyson Stoner voiced her.
* TrollingCreator: To some extent; that [[spoiler:pod of Experiment 628]] seen at the end of "627"? That was just a joke added in.
* WhatCouldHaveBeen:
** Precious (Experiment 400) was meant to have her own episode as a parody of ''Literature/TheLordOfTheRings'' where she would be thrown into an [[ChekhovsVolcano active volcano]] where the extreme heat from the lava would defeat her but alas, the idea was scrapped due to copyrights. Now why they couldn't use [[MagmaMan Yang]] for a [[FridgeBrilliance lava source]] is beyond anybody's guess.
** Spot (Experiment 099) was supposed to appear in "Spike", but the experiment wasn't added to the episode and remains unseen to this day.
** In a [[https://www.youtube.com/watch?v=f4QWt8Hbl4g conceptual storyboard for "Ace"]] by Sahin Ersöz, Jumba was supposed to be expelled from E.G.O. for saving Pleakley from a tidal wave staged by Lilo, Stitch, and some of the other experiments. Unfortunately, [[ExecutiveMeddling Disney's Standards and Practices didn't approve of this]], hence why it was changed to Jumba showing the head of E.G.O. [[ClipShow footage of the experiments]] instead.
