History Manga / MobileSuitGundamTheOrigin

* ColonyDrop: Operation British was intended to drop a colony on the Federation's headquarters at Jaburo in the Amazon. The colony was partially destroyed by a Federation fleet that just happened to be at the right place in the right time to intercept it, and tried to destroy it. The destruction was still enough for the colony to break up into three sections, which fell onto southeast Australia, southwest Canada, the western portion of the Pacific ocean. The resulting impacts, ensuing natural disasters, famines, and lack of medical care against diseases killed just over ''50% of the population of Earth''.

* SuperPrototype: Downplayed compared to the original -- only the Gundam itself is a prototype in this version, while the Guncannon is a previous Federation attempt at fielding mobile suits (failed because, while excellent at attacking ships and supporting infantry, it is ''pathetic'' at fighting other mobile suits, while even the Zaku I can both outfight it and perform reasonably well in other missions) and the Guntank is a ''tank'' (or possibly a [[TanksButNoTanks self-propelled artillery vehicle]]) with a humanoid torso, and both were already mass-produced and used in the field (with the Guntank's deployment preceding the development of mobile suits by ''years'').

* TanksForNothing: {{Downplayed}} with the Guntank. It still sees a few victories but it was the first of the mobile suits to be mass produced and its flaws really show when MS development moves into full swing. The Guntank is more similar to a vehicle rather than a conventional mobile suit which is fitting because it's essentially just an upgraded Federation Tank. Though it's got heavy armor, heavy fire-power, and all terrain treads; all of these get surpassed. Conventional Mobile Suits can move and fly far more easily than the Guntank, it's armor cannot protect it from the developing beam weaponry, and it has no opposable manipulators or means to defend itself in close quarters combat. Its main positive, firepower, is best for long range fighting and even then has to compete with mega-particle cannons and other heavier guns.
* TechnicallyATransport: Turns out Zeon's iconic ''Musai''-class light cruiser is this: it was originally built and mass-produced as the ''Arcana''-class transport ship, and in the build-up to the war they were modified, including the installation of weapons and armor. In a twist, it's implied it was an ''intended feature'', as the bow was built from the start to be able to deflect and absorb beam weapon shots, thus allowing Zeon to build up a powerful fleet under the Federation's nose and then convert them in a proper battlefleet capable of challenging them in less than a year.

** One notable change is that in Episode 2 of the OVA, Jimba Ral talks about gaining the support of Anaheim Electronics, which wouldn't be formed until after the One-Year War in the original series.
** Also, in ''The Origin'', the Federation was producing Guntanks and, eventually, Guncannons before the outbreak of the One-Year War (designated as "Early Types" to differentiate them from the "Project V" versions). In the the original anime, the Federation didn't have any mobile suits whatsoever until the development of the Gundam.

* MultiethnicName: General Revil's middle name (usually rendered as Abraham) is given the Arabic spelling, Ibrahim, in the Vertical Inc. translation, possibly to highlight the multicultural nature of the Earth Federation.

The series is the third of its kind and follows many of its plot elements while expanding on those elements and adding unique elements of its own. The plot is the same as the original series and is as follows:

* EyeDentityGiveaway: [[spoiler:Char Aznable wears Cool Shades, and later a Cool Mask, almost constantly claiming he has a pigmentation issue with his eyes to hide the fact he has blue eyes which doesn't match up with documentation saying that the real Char has brown eyes. The real man behind the mask and glasses is Casval.]]

* AnachronicOrder: The multi-book flashback arc starts immediately after the Jaburo invasion ends and then snaps back to the White Base leaving South America. Interestingly, this strongly parallels the oft-recommended "Machete" viewing order for the pre-Disney ''Franchise/StarWars'' films[[note]][[Film/ANewHope IV]], [[Film/TheEmpireStrikesBack V]], [[Film/ThePhantomMenace I]] ([[DisContinuity assuming it isn't simply skipped over]]), [[Film/AttackOfTheClones II]], [[Film/RevengeOfTheSith III]], [[Film/ReturnOfTheJedi VI]].[[/note]], the end of the Jaburo arc being where the second CompilationMovie ended. It's not a perfect fit though, since the Europe arc, which while heavily truncated in the movies still contains a few pivotal moments such as Miharu's infiltration of the White Base, was shuffled to after Jaburo in ''Origin''.
