----
* AlternativeCharacterInterpretation: Is Gantu's VillainDecay due to lazy writing, or being fired from the Council in the original movie (and being reduced as servant of a hysterical rodent) made him fall into a depression so deep it directly affects his performances?
** Said new job could also be leading to him going out of shape and thus not as active as he used to be. Could explain why he gets exhausted at some points.
*** It'd seem to be confirmed with ''WesternAnimation/TheProudFamily'' crossover episode, where the first time we see Gantu, he's trying to train and flat out admits that he's out of shape. (His humiliating defeat by Suga Mama's hand, in this perspective, would be due to WorfHadTheFlu rather than NeverMessWithGranny.)
* {{Anvilicious}}: The strong emphasis on ''[='=]ohana'' (family).
* AssPull:
** In "Angel", Lilo only finds out Angel is working for Hämsterviel because of a tag she saw around her neck on the video Pleakley took. Angel never wore the tag any other time.
** The ''[[TyrannosaurusRex T. rex]]'' at the end of "Retro". We never see how Retro made that. Though it could be assumed that he used his powers on a chicken (the ''T. rex''[='=]s closest relative out of all things) or some other type of bird.
** In "Snafu," Angel releases everyone from their capsules by [[spoiler:knocking her head against the glass. Apparently, super-strong experiments can't break those capsules without ThePowerOfLove]].
* EarWorm: [[https://www.youtube.com/watch?v=GdbDPovhAW8 "Aloha, E Komo Mai"]], with its fun, feel-good sound.
* EvilIsCool: [[TheJuggernaut 6]][[AlwaysSomeoneBetter 2]][[OneShotCharacter 7.]]
* FanficFuel: Since Stitch has over 600 different cousins, it's not hard to write a fanfic featuring one of them.
* HilariousInHindsight:
** [[WesternAnimation/AmericanDad Pleakley isn't the only flamboyant alien hiding out amongst a family who loves dressing up.]]
** Also, [[WesternAnimation/SuperNoobs Jumba and Pleakley aren't the only two intergalactic alien agents who live on Earth in a single house as roommates and help out a child with an important mission that decides the fate of he universe.]]
** In "Short Stuff", 625 declines helping Gantu because he has "half a Reuben" left to eat.
** Four trailers for the first movie featured Stitch gatecrashing several [[Franchise/DisneyAnimatedCanon animated Disney movies]]. In season two, four episodes have characters from other Disney shows [[{{Crossover}} crossing over]]. Revenge is had, kinda...
* HoYay:
** Pleakley. True, it can be given in the beginning his "aptitude" with Earth customs is lacking, but early on... he openly tries girl's clothing. He also seems to crush on Jumba. Ironically, this seems to be a '''Disney''' subversion of HideYourLesbians.
** Jumba and Pleakley continue to live together in a single house, continue to play husband and wife a lot in private and in public, and they share a bed (to be more fair, they share a bunk bed so they technically sleep in separate beds).
** The VerySpecialEpisode where Pleakley's family try to make him get married--he's very reluctant until the 'bride' is Jumba in a dress, and in the end his family accept that Pleakley's happier without a wife. He also promised to wear men's clothes, which set off [[LivingLieDetector Fibber]]. Meaning he intends to keep wearing women's clothes and never has any intention of ever wearing man's clothes.
** There was also a scene between Jumba and Pleakley where they rip off the airport scene from ''Film/{{Casablanca}}''.
** And the [[HotSkittyOnWailordAction relationship between him and Jumba]] seems to go both ways: Jumba occasionally addresses him as "my little one-eyed one." Awwww.
** ActorAllusion, ActorAllusion, ActorAllusion! Pleakley is voiced by Kevin [=McDonald=], of ''Series/TheKidsInTheHall'' fame. The man is used to playing characters in dresses. Not only that, but his family members in said episode were voiced by old castmates [=Bruce McCulloch=], [=Mark McKinney=], and Scott Thompson, with Dave Foley playing the priest.
** Jumba's VoiceActor, David Ogden Stiers, came out of the closet in early 2009.
** "Jumba and I have found the secret of love!" Oh, Pleakley.
** Hunkahunka's peck, which causes the target to fall in love with the first person they meet, is decidedly gender-blind, leading to at least three instances in the episode where a male character falls in love with another. Gantu was a constant victim of this as the experiment's pecks caused him to fall in love with Pleakley (who he mistook for a woman because Pleakley was wearing a dress at the time) and Stitch. Pleakley also flirts with five surfer dudes while cross dressing in the same episode, only to get rejected by all of them.
** The relationship between Gantu and Reuben has some HoYay in it as they live together in Gantu's crashed spaceship and Reuben often makes some snarky but somewhat silly comments towards Gantu about his looks. They even bicker LikeAnOldMarriedCouple due to being VitriolicBestBuds in ''The Series''.
* JerkassWoobie: Gantu occasionally gets his moments in episodes like "Dupe" and "Phoon", where he questions his own life and failures. In "Amnesio", when he loses memory, in a CallBack to [[Disney/LiloAndStitch the original film]], he says [[NotSoDifferent "I'm lost."]]
* MostAnnoyingSound:
** "YEEEEEEAAAAH!"
** Fibber's buzzing noise and Belle's scream, though that's kind of the point.
** The ''[='=]ohana'' motto. Proof that, with enough repetition, anything can be unbearably annoying. This was funnily enough mocked and [[LampshadeHanging Lampshaded]] by the title experiment of the episode, "Heckler".
* SugarWiki/MostWonderfulSound: Angel's singing. Thank you, Creator/TaraStrong.
-->'''Stitch''' ''(to Angel)'': Nice pipes!
* TheScrappy: Keoni. He's a bland AudienceSurrogate who adds nothing to the plot, and Lilo's crush on him tends to bring out the absolute worst in her.[[note]]Contrast with Angel and Stitch, since the former's presence tends to bring out the outright best in him.[[/note]] [[CreatorBacklash Even the writing staff hated him.]]
* SoOkayItsAverage:
** It's a pretty decent show to watch and it has plenty of entertaining moments, but it could have been so much better if it weren't for the ExecutiveMeddling (making it badly LighterAndSofter with all those [[AnAesop aesops]]), the [[SixtyFiveEpisodeCartoon 65-episode limit]], [[TheyWastedAPerfectlyGoodCharacter the squandered potential of the experiments]] due to having to stick to the MonsterOfTheWeek trope, the {{Flanderization}} of the core cast, the repetitiveness of the GottaCatchEmAll aspects of this show, and Disney overmilking the franchise for what it's worth during [[TurnOfTheMillennium the 2000s decade]].
*** In fact, some fans prefer the [[BrokenBase otherwise-controversial]] [[Anime/{{Stitch}} anime]] over ''The Series'' because of everything above, especially the obvious ExecutiveMeddling.
* TearJerker:
** In the Halloween special, we get Spooky who can shapeshift into people's worst fears. For Lilo, he turns into a MonsterClown. For Stitch, he turns into water. For Jumba, he turns into his ex-wife. For Pleakley he turns into his mother. What does he turn into for Nani?
-->'''Nani''': Cobra Bubbles?\\
'''Spooky''' ''(as Cobra)'': I'm here to take Lilo away.\\
(''[[AdultFear Nani looks appropriately terrified.]]'')
** Then there's the episode "Remmy", where both Lilo and Nani are depressed throughout the majority of the episode, due to it being the anniversary of their parents' death.
* TheyWastedAPerfectlyGoodCharacter:
** Victoria, the red-headed girl Lilo befriends. It's obvious the writing team struggled with her then just gave up altogether. A pity, she had a cute design.
*** Arguably, she also would have made a much better AudienceSurrogate than [[TheScrappy Keoni]], since Lilo was obviously not portrayed as having an obsessive crush on her.
** Experiment 627. How can you use such a powerful antagonist as a mere MonsterOfTheWeek?! Couldn't he have been more effective as recurrent villain? Or as the FinalBoss, instead of a dull [[WesternAnimation/LeroyAndStitch red doppelganger of Stitch]]?
*** Really, a ''lot'' of [[Characters/LiloAndStitchExperiments the experiments]]. Some episodes, such as "Spike", showed some potential of how their personalities could be fleshed out if they were given more screen time (like in the E.A.R.W.A.X. scenes in that particular episode), but the MonsterOfTheWeek setting combined with the [[SixtyFiveEpisodeCartoon 65-episode limit]] ruined such hopes, with many experiments relegated to being {{flat|Character}} background characters. Even some popular experiments like Angel (624) didn't get that much further characterization in the episodes they appear in. Granted, the ''Anime/{{Stitch}}'' anime did help to fix this problem, but [[BrokenBase then]] [[FanonDiscontinuity again...]]
** Hämsterviel (who is based on Dr. Habbitrale from the video game ''Stitch: Experiment 626'') and 625/Reuben (from ''Magazine/DisneyAdventures'' magazine) are {{Canon Immigrant}}s without problems. Why 621 (from the aforementioned game) [[ChuckCunninghamSyndrome didn't make it?]] He would've been a WorthyOpponent for Stitch throughout all ''The Series''. Heck, given his thirst for revenge against 626, it could've been him the titular experiment of episode 19 (627's), unleashed by Jumba to give Stitch a lesson about his ego, and, as aforementioned, keeping 627 as recurrent antagonist/GrandFinale's enemy.
** In the {{Crossover}} episodes, the guest characters are very bland versions of their original selves. This takes away very much from the plot's premises.[[note]]It isn't even a problem of this series in particular. It looks like crossovers are Disney writers' AchillesHeel. Watch [[https://www.youtube.com/watch?v=XUDOtFPE-V4 "Hercules and the Arabian Night"]] from ''[[WesternAnimation/{{Hercules}} Disney's Hercules: The Animated Series]]'' for some proof.[[/note]]
* TheyWastedAPerfectlyGoodPlot:
** In the episode where Lilo is hypnotized into acting like Mertle, they missed a perfect opportunity to have Mertle say Lilo was acting weird. Instead, one of Mertle's friends points out that Lilo is acting like her and nothing more is said about it.
** Also the episode "Dupe": Gantu finds four unactivated experiment pods and turns them into a Four Man Strike team against Lilo and Stitch. After they are defeated in the climax of the episode, the experiments never show up again, save for the finale, "Snafu", where they are Gantu's prisoners.
** "Rufus": Why Jumba didn't meet Drakken? It would have been interesting! In fact, the entire episode would have been better if they'd exploited Jumba's CardCarryingVillain attitude toward the ''WesternAnimation/KimPossible'' cast, instead of just making him chase a poor naked mole rat.
** "Spats": [[CausticCritic Mr. Cooper]]'s subplot is superfluous, being a one-shot original character in the middle of a crossover between two series' estabilished casts. Not exactly "perfectly good", maybe, but nonetheless it could have been a totally separated episode.
* ViewerGenderConfusion:
** Quite as few people mistook Pleakley for a woman. Which is fairly easy to assume, since he only wears dresses, and disguises himself as a lady in public.
** Yin (501) gets a lot of this as well. An extremely feminine experiment, he/she is often labelled a female by viewers (not to mention several wikis), despite Lilo referring to him/her as a male repeatedly.
** Same goes for Shush (234), who's much less feminine than Yin and was also referred to as male in its episode, yet fan wikis label the experiment as female.
* VillainDecay: Gantu turned from the imposing but somewhat {{Anti Hero}}ic thirty-something-foot-tall military captain from the original movie into a much shorter bumbling idiot who even proclaims that he "likes to be evil". Subverted at the end of ''The Series'' when it doesn't work out for him and [[HeelFaceTurn gets his old job back.]]
* WhatAnIdiot:
** Houdini is an extremely timid, extremely gun shy experiment with the power to make things disappear. Where does Lilo reckon his "one true place" lies? As a star magician on TV, naturally.
*** He returns to Kokaua Town in "Snafu", performing a magic trick on the streets. Either Hollywood helped him with shyness (which would be very surprising), he got out of Hollywood to go back to the small town, or both.
** Also, why does Lilo persist in trying to bond with Mertle and her gang?! It's clear there's no affinity whatsoever! It is understandable that she tried ''before'' meeting Stitch (and Victoria, despite her very poor screentime), and she couldn't avoid them anyway, due to [[TheFriendNobodyLikes proximity]] stuff, OK, but despite having now real friends, Lilo clearly still thinks she can go along with those brats! No, Lilo. Just no.
*** Well, Mertle did appear at the end of ''Leroy & Stitch'' smiling with the Pelekai ''[='=]ohana'', so things may have actually worked out for the better.
