''Leroy & Stitch'' (2006) is the GrandFinale movie of ''WesternAnimation/LiloAndStitchTheSeries'', and is the last movie in the Disney/LiloAndStitch franchise.

Having captured all six-hundred and twenty-five experiments, Lilo and the gang are rewarded by the Grand Councilwoman for their good work. Jumba gets the key to his old lab, Pleakley gets a post as head of Earth Studies at the Galactic Alliance Community College, Stitch is granted a commission as a captain of the armada, and Lilo becomes ambassador between Earth and the Galactic Federation. However, this means they will have to split up, and after a sad goodbye, they go their separate ways.

However, Hamsterviel has once again escaped, and he seeks to wrest control of the Federation, with the forced help of Jumba and his newly-running laboratory.

----
!!''Leroy & Stitch'' provides examples of:
* {{Ambadassador}}: Lilo to the Galactic Federation.
* BrilliantButLazy: Reuben, who up until now has spent the series making sandwiches and wisecracking at Gantu, gets a CrowningMomentOfAwesome when he successful repairs Gantu's crashed ship, something Gantu had been unable to do all series.
* ChairReveal: In this case, also a type of ChekhovsGun.
* ChekhovsArmoury: Lilo's departing gifts to Stitch, Pleakley and Jumba. Stitch's gift was a tiki necklace which [[spoiler:allowed Lilo to identify Leroy as an imposter because he wasn't wearing it]]. Next was a rock given to Pleakley that was used to [[spoiler:disrupt the event horizon of a black hole that he, Stitch and Jumba were hurtling into and allow them to escape]]. Finally there was the Aloha 'Oe record given to Jumba which he used to [[spoiler:create a secret mechanism in Leroy that made him shut down if he (or his clones) heard it. This ends up leading to both a [[CrowningMomentOfAwesome Crowning Moment]] and a CrowningMusicOfAwesome the end where Stitch, Lilo, [[strike:625]] Reuben and a bunch of Stitch's cousins put on a concert to defeat the Leroy clone army at the end]].
* ContinuityNod: Nani and Lilo's talk on the hammock.
** At one point during his battle with Stitch, Leroy is smushed under a pile of wreckage. His emergence from the rubble is very similar to Stitch's in the first movie.
** The frog from the first movie makes an appearance in a scene.
** While Leroy is scouting Lilo's room, he pulls out a bunch of books from Lilo's bookstand, looks at them and chucks them away, much like Stitch in the first movie. One of the books that catches his attention is The Log Book (a [[ExactlyWhatItSaysOnTheTin book about logs]]) which Stitch also looks through in the first movie.
** He also steals a can from the fridge, like Nani catches Stitch doing in the first movie.
** Leroy steals the experiment photo album Lilo was compiling in the last episode of the series.
** Hamsterviel uses a pile of books to make himself look taller, just as he does in WesternAnimation/StitchTheMovie.
** At the beginning of 'Aloha 'Oe', Stitch breaks one of his guitar strings.
* ContinuityCavalcade: Almost every experiment from the previous series gets a scene, usually in one of three sequences in the film: at the beginning of the movie as Jumba's ship takes off, shown in their new lives before being captured by Leroy, or in the battle with the Leroy clones.
* ContrivedCoincidence: Why would the black hole drop them off right where Lilo and Reuben were?
* DoesThisRemindYouOfAnything: Pleakley on the phone to Jumba: "Don't you miss your Aunt Pleakley? I'm wearing the wiiig...!" We've gone ''way'' past subtext at this point.
* EvilRoy: Leroy is the prime epitome of this trope, as Jumba was ''forced'' to create him, under orders from his former science partner Doctor Hamsterviel.
* ExactlyWhatItSaysOnTheTin: The Log Book is a book about logs.
* GrandFinale: For the series.
* GoodColorsEvilColors: Stitch is colored blue, while Leroy is colored red.
* IChooseToStay: [[spoiler: Stitch, Jumba, and Pleakly in ''Leroy and Stitch''.]]
* ImperialStormtrooperMarksmanshipAcademy: The robot security drones at the prison asteroid as Gantu attempts to free Hamsterviel.
* KidnappedScientist: Jumba is kidnapped ([[WesternAnimation/StitchTheMovie again]]), this time in order to create a new genetic SuperSoldier ("Leroy") for Hamsterviel to make an army of clones of.
* LogoJoke: After the logo is formed, the background turns into space as the castle goes into hyperdrive.
* MementoMacGuffin: Stitch's tiki.
* MistreatmentInducedBetrayal: Hämsterviel is dumb enough to tell Gantu that he'll be fired as soon as he's finished locking up Lilo and Reuben. Naturally, Gantu decides that he's got nothing to lose, and releases them.
* {{Mooks}}: the Leroys.
* NoNameGiven: Inverted for Leroy - he is given a name but no number.
* PuppyDogEyes: Played straight with Lilo in the opening scene.
* PutTheirHeadsTogether: Angel does this to two of the Leroy clones.
* RhetoricalQuestionBlunder: Hämsterviel has the following conversation with minion Gantu:
-->'''Hämsterviel''': I think that went very well, don't you?
-->'''Gantu''': Actually, I think...
-->'''Hämsterviel''': I did not ask you what you think!
-->'''Gantu''': Actually, you did. I...
-->'''Hämsterviel''': No! It was a rhetorical question! Don't you know what a rhetorical question is?
-->'''Gantu''': Yes, sir. I believe it's...
-->'''Hämsterviel''': No, no! That was a rhetorical question too! Argh!
* SeriesFauxnale
* ShipTease: Jumba and Pleakley get quite a bit of it this go around, as do Bonnie and Clyde -- in the group portrait at the end, he's got his arm around her and she's leaning into him.
* SingleSpecimenSpecies: All the experiments. Even Leroy, if you don't count the cloning.
* ShoutOut: The Series/HawaiiFiveO theme plays as Leroy captures all the experiments.
** Hamsterviel sends Jumba, Pleakley and Stitch to co-ordinates 12-21-979, the location of a black hole. The release date of Film/TheBlackHole was December 21st, 1979.
** Jumba cranks up the volume of the amplifier for the end song "up to evil [[ThisIsSpinalTap eleven]]".
* TenMinuteRetirement: Hamsterviel to [[spoiler:the Grand Councilwoman.]]
* TheMovie
* ThemeMusicPowerUp: Aloha Oe.
** Actually an ''inversion'', believe it or not - [[spoiler:if Leroy hears the song, he shuts off, a switch that also applies to his clones. Naturally, Lilo, Stitch, and co. perform a rockin' concert to accomplish this. So it's really more of a Theme Music Power Down for the villains.]]
* TrademarkFavoriteFood: Since 625's trademark food is sandwiches, this leads Lilo to name him after one.
