[[caption-width-right:233:[[CoversAlwaysLie This cover is the best thing about it.]]]]

Those of you who are familiar with Joseph Lai's body of work, this is ''Thunder Prince'' [-{{IN SPACE}}-]. A very, very bad HumongousMecha pseudo-anime released in 1991 about three children (or three teams with three children each depending on how you interpret it) that can pilot giant robots trying to defeat the BigBad and his army: the Dark Empire. There are also some SpaceOpera elements thrown in with advanced space stations and dogfights going on in space.

This decidedly weird animated film is a result of Joseph Lai buying South Korean cartoons on the cheap and editing them to make "new" features. The result is a benchmark case of CutAndPasteTranslation after putting all the different shows together.

This "film" was edited with footage from ''Savior of the Earth'', ''Defenders of Space - Phoenix-bot Phoenix King'', ''King Robot'', ''Protectors of Universe - Super Express Mazinger 7'', ''Solar Adventure'', ''Animation/SpaceTransformers - Micro-Commando Diatron-5'', ''Super Mazinger 3'' and ''Iron Man Trio''. All of the aforementioned movies are also ripoffs of other anime like ''Anime/MazingerZ'' (and all but the last were separately dubbed by Joseph Lai as well).

Has nothing to do with ''Anime/UFORoboGrendizer''[='s=] FinishingMove.
!!This film provides examples of:

* AbortedArc: A lot of these. Or are there? Thanks to the constant art shifts, it is hard to tell what is and what isn't supposed to be there.
* AllThereInTheManual: It's a good thing the back of the cover describes the ''entire'' movie from start to finish, because otherwise we'd never know what we were watching. Apparently somewhere during the hour-and-a-half of tanks and explosions is the plot about saving a scientist.
* ChildSoldiers: The main characters.
* CoversAlwaysLie: None of the characters on the cover are actually in the movie. Unless they look completely different in the film proper, of course...which isn't much of a stretch, really.
* CutAndPasteTranslation: Definitely a lot of these. The same characters changes their appearance completely from scene to scene.
* DecoyProtagonist: Who the hell are the space thunder kids? There's a random focus on at least three different space travelling groups, but none of them do anything of importance, and none of them ever last longer than a scene or two. Eventually it becomes impossible to discern who's supposed to be the bad guys and who are the heroes, because all the ships look the same.
* DetailHoggingCover: If only the movie looked that good...
* TheEmpire: The forces of Earth are supposedly fighting one.
* EpicFlail: Some of the giant robots of the Dark Emperor fight with these in space, [[SpaceFriction Newton's laws be damned]].
* {{Filler}}: Hey, check out this animation cycle of rolling tanks we have! Isn't it great? Let's loop it for 5 minutes straight!
* GalacticConqueror: The Dark Emperor.
* HeelFaceTurn: The general (who is North Korean communist dictator Kim Il Sung) at the end.
* HongKongDub
* InexplicablyIdenticalIndividuals: The lines of civilians running away from the buildings being leveled by Neon Light Godzilla.
* LoadsAndLoadsOfCharacters: Perhaps unintentionally, as a result of this film being an attempt to mash several films together. The Dark Emperor has a lot of lieutenants.
* LullDestruction: Averted; there are many moments of [[SilenceIsGolden dead air]] throughout, a rarity in for English-dubbed "anime".
* NoCelebritiesWereHarmed: Kim Il Sung, as the evil general working with the aliens.
* OffModel: Instance include pulling someone ''through'' the windscreen of a jeep, [[http://www.youtube.com/watch?v=_6-Hi755Rb4 the face one of the heroes makes]], the lip flaps, the [[http://www.youtube.com/watch?v=voaK8wL3vz4 tanks tanks tankstankstanks]]...
** Arguable, since this trope implies that a majority of the work is on-model.
* RandomEventsPlot
* RecycledInSpace: Around the same time, Lai had produced movies entitled [[Film/GodfreyHoNinjaMovies "Thunder Ninja Kids".]] Presumably this work's title is referencing that. It's fitting: given the subpar CutAndPasteTranslation treatment, it could ''almost'' be the Film/GodfreyHoNinjaMovies [-ANIMATED! IN SPACE!-]
* ShoddyKnockoffProduct: The film itself, even more so than the already knocked-off films it was based on.
* SpaceDoesNotWorkThatWay: The animators must not have paid attention in science class.
** During fight scenes, the background will often change in the middle of shots between space and the ''sky'', leaving you wondering just where they are supposed to be fighting.
* SpaceFriction
* SpaceIsAnOcean: Inverted, Averted, Subverted, Played Straight, Zigzagged, and Hung Out To Dry. The movie[[CutAndPasteTranslation s]] can't decide whether or not this trope is in play. Some points even have spaceships that are [[BlatantLies totally absolutely not]] ''Anime/SpaceBattleshipYamato'', and at one point, speeds are called out in ''knots''. Not even hundreds or thousands of knots, as would be the case for spaceships if they didn't just use [=MpH/KpH=] to begin with, but tens of knots, as if they were going at nautical speeds. Other parts have (by this movie's exceedingly lax standards) passingly realistic space motion.
* SpaceIsNoisy
* StockFootage: Taken to a whole new level with this film.
* StrongFamilyResemblance: Subverted doesn't even begin to describe it. Apparently the seven foot tall one eyed blonde space pirate badass vixen has a sister who is... a one foot tall robot... pig... thing... named Sandy.
* TrailersAlwaysLie: Inverted; the "[[http://www.youtube.com/watch?v=NPIR_S1Zrcc trailer]]" found online? The repeated exclamations of ''SPACE THUNDER KIDS''? That's in the actual ''film''.
* WhatHappenedToTheMouse: The space station that was attacked by the meteors at the beginning were never seen again. Either that or [[ArtShift the space station was drawn differently from there on out.]] Who knows?
** The tanks.
* WidgetSeries: A special case, in that it's a Weird Korean Thing assembled from half a dozen or more ''other'' Weird Korean Things.
