* {{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.
** 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?
* DudeNotFunny: Nani's treatment of Stitch sometimes gets this, most notoriously in "Phantasmo".
* 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.]]
* 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.
** Not to mention 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.
** Not to mention that 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.
* 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.
* RomanticPlotTumor: Stitch and Angel's relationship.
* 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]]'')
* 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.
* 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.
*** Thats because he sent them to Hamsterveil, who held on to them until said finale.
* UnfortunateImplications: Stitch calls the other Experiments his "cousins" but Jumba created them all, so that makes them more like brothers and sisters. [[BrotherSisterIncest Now consider his crush on Angel]].
* 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.
* 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.
