- Alternative Character Interpretation: Is Gantu's Villain Decay 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).
- Ass Pull:
- 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 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 capsules by knocking her head against the glass. Apparently, super-strong experiments can't break those capsules without The Power of Love.
- Evil Is Cool: 627.
- Hilarious in Hindsight:
- Pleakley isn't the only flamboyant alien hiding out amongst a family who loves dressing up.
- In "Short Stuff", 625 declines helping Gantu because he has "half a Reuben" left to eat.
- Ho Yay:
- 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 Hide Your Lesbians.
- The Very Special Episode 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 Fibber. Meaning he intends to keep wearing women's clothes and never has any intention of ever wearing man's clothes.
- And the relationship between him and Jumba seems to go both ways: Jumba occasionally addresses him as "my little one-eyed one." Awwww.
- Actor Allusion, Actor Allusion, Actor Allusion! Pleakley is voiced by Kevin McDonald, of The Kids in the Hall 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 Voice Actor, 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.
- Jerkass Woobie: 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 Call Back to the original film, he says "I'm lost."
- Most Annoying Sound:
- 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 Lampshaded by the titular experiment of the episode, "Heckler".
- The Scrappy: Keoni. He's a bland Audience Surrogate who 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.
- So Okay, It's Average: 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 Executive Meddling, the 65-episode limit, the squandered potential of the experiments due to having to stick to the Monster of the Week trope, the Flanderization of the core cast, the repetitiveness of the Gotta Catch 'Em All aspects of this show, and Disney overmilking the franchise for what it's worth during the decade.
- Tear Jerker: In the Halloween special, we get Spooky who can shapeshift into people's worst fears. For Lilo, he turns into a Monster Clown. 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.
(Nani looks appropriately terrified.)
- They Wasted a Perfectly Good Character:
- 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.
- Experiment 627. How can you use such a powerful antagonist as a mere Monster of the Week?! Couldn't he have been more effective as recurrent villain? Or as the Final Boss, instead of a dull Stitch's red doppelganger?
- Really, a lot of 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 Monster of the Week setting combined with the 65-episode limit ruined such hopes. Even some popular experiments like Angel (624) didn't get that much further characterization in the episodes they appear in.note Granted, the Stitch! anime did help to fix this problem, but then again...
- Hämsterviel (who is based on Dr. Habbitrale from the video game Stitch: Experiment 626) and 625/Reuben (from Disney Adventures magazine) are Canon Immigrants without problems. Why 621 (from the aforementioned game) didn't make it? He would've been a Worthy Opponent for Stitch throughout all The Series. Heck, given his thirst for revenge against 626, it could've been him the titular experiment of Episode 23 (627's), unleashed by Jumba to give Stitch a lesson about his ego, and, as aforementioned, keeping 627 as recurrent antagonist/Grand Finale'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
- They Wasted a Perfectly Good Plot:
- 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 Card-Carrying Villain attitude toward the Kim Possible cast, instead of just making him chase a poor naked mole rat.
- Viewer Gender Confusion:
- 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.
- 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.
- Villain Decay: Gantu turned from the imposing but somewhat Anti Heroic 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 gets his old job back.
- What an Idiot:
- 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! 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 proximity stuff, OK, but despite having now real friends, Lilo clearly still thinks she can go along with those brats! No, Lilo. Just no.
