* 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?
* {{Anvilicious}}: The strong emphasis on 'ohana' (family.)
* AssPull: In "Angel" Lilo only finds out Angel is working for Hamsterviel because of a tag she saw around her neck on the video Pleakley took. Angel never wore the tag any other time.
** The 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 or some other type of bird.
** In "Snafu," Angel releases everyone from their pods by [[spoiler: knocking her head against the glass.]] But wait, why didn't she just do that earlier?
* EnsembleDarkhorse: Angel (#624), who recently got her own toy (only at Disney Parks, though) And of course, [[EnsembleDarkhorse Reuben]] (#625).
** Many of the other experiments as well, most noticeably: Sparky (#221; popular enough to be a mandatory BossBattle in ''VideoGame/KingdomHeartsBirthBySleep''), Yin (#501), Yang (#502), 627, Bonnie (#149), Clyde (#150) and most peculiarly, Slushy (#523).
* EvilIsCool: 627.
* FanNickname: 627 is referred to as 'Evile' by some.
* FanPreferredCouple: As of Feb 16 2011, there are no stories involving Lilo and Keoni Jameson (her crush in the series) on Fanfiction.net; there are quite a lot that pair her up with Stitch. Squick or Squee.
* GermansLoveDavidHasselhoff: Angel, the [[PinkGirlBlueBoy pink]] DistaffCounterpart version of Stitch introduced in the series, is ''extremely'' popular in Japan. She has something of an AscendedExtra status there.
* HilariousInHindsight: [[AmericanDad Pleakley isn't the only flamboyant alien hiding out amongst a family who loves dressing up.]]
** In "Short Stuff", 625 declines helping Gantu because has "half a Reuben" left to eat.
* 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. Also seems to crush on Jumba. Ironically, this seems to be a '''Disney''' subversion of HideYourLesbians.
** 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 the lie detector experiment. Meaning he intends to keep wearing women's clothes and never has any intention of ever wearing man's clothes.
** 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 ''KidsInTheHall'' 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.
* 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" speech. Proof that, with enough repetition, anything can be unbearably annoying.
* 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]]'')
* TheScrappy: Keoni. He's a bland AudienceSurrogate that adds nothing to the plot, and Lilo's crush on him tends to bring out the absolute worst in her. Even the writing staff hated him.
* 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.
** Also, 627. How can you use such a powerful antagonist as a mere MonsterOfTheWeek?! Couldn't he've been more effective as recurrent villain? Or as the FinalBoss, instead of a dull [[WesternAnimation/LeroyAndStitch Stitch's red doppelganger]]?
** Hamsterviel (the Habbitrale from the videogame "Stitch: Experiment 626) and 625 (from Disney Adventure Magazine) are CanonImmigrant 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, it could've been him the titular experiment of Episode 23 (627's), unleashed by Jumba to give Stitch a lesson about his ego.
** 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.
* TheyWastedAPerfectlyGoodPlot: In the episode where Lilo is hypnotised 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 their defeated in the climax of the episode, the experiments never show up again, save for the finale, "Snafu", where their Gantu's prisoners.
** At the end of ''Leroy and Stitch'', Gantu is reinstated as Captain of the Galactic Armada, with Reuben recruited as his right-hand-man, opening the door for a SpinOff of the two. When they return in "Stitch!", both have been fired from the Armada due to their poor karaoke singing, and have rejoined Hamsterviel.
** "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.
* 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 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.
* VillainDecay: Gantu turned from the imposing but somewhat {{Anti Hero}} 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.
** Also, why does Lilo persist in trying to bond with Mertle and her gang?! It's clear there's no affinity whatsoever! I comprehend that she tried before meet Stitch (and Victoria, despite her very poor screentime) and that she can't avoid them, 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.
