* IdiosyncraticEpisodeNaming: Episodes 41 to 43 are all titled "Mortal ______" with the second word relating to falling from a height (Pinnacle, Precipices and Fall).

** Conversely, the Imperium is on the receiving end of this from the Sith. Despite their brutality and fanaticism exceeding that of the Sith, the Imperials aren't being willfully malicious or cruel, just ''[[KnightTemplar deeply]]'' [[ObliviouslyEvil misguided]] and [[PoorCommunicationKills misinformed]] after being tossed into an [[WrongGenreSavvy unfamiliar setting that operates on different rules from their own.]] Yes, the Imperials are explicitly trying to conquer the ''Star Wars'' galaxy and commit a bevy of atrocities along the way, but they only do so out of the ''genuine'' belief that it's [[NecessarilyEvil necessary to survive]] and keep humanity safe. By contrast, the Sith are [[CardCarryingVillain fully aware their actions are evil]] and causing harm to innocents -- and either [[LackOfEmpathy don't care]] or [[{{Sadist}} actively get a sick thrill from it]]. Unlike the Imperium, the Sith seek galactic domination not because they think it's in anyone's best interests, but primarily to [[ItsAllAboutMe massage their own egos]]. So far, there have been two instances in the series where the Sith have actively joined the battlefield -- Dooku vs. a squad of Crimson Razors on Raxus Secundus and [[spoiler:Sidious vs. Tahr Whyler on Axum.]] In both instances, the Sith win handily and defeat their Imperial opponents.

** This is one of the Imperium's biggest problems in the story; they assume the concept of "AliensAreBastards who prey on PunyEarthlings" universally applies to the ''Star Wars'' galaxy the same way it does in the ''40K'' galaxy, and thus conclude that the ''SW'' alien races are AlwaysChaoticEvil monsters that they can kill ''en masse'' [[GuiltFreeExterminationWar without any guilt or consequences]]. Of course, the problem is that the ''SW'' universe ''doesn't'' function with the same rules as ''40K''; if anything, the ''SW'' galaxy runs more on HumansAreTheRealMonsters and InnocentAliens. Because of this, the Imperials wind up massacring tons of innocent people who did nothing wrong -- an act so heinous that it crosses the in-universe MoralEventHorizon and ensures the Imperials will be HatedByAll in the ''SW'' galaxy.

So the Imperials believe the ''SW'' alien races are AlwaysChaoticEvil monsters that they can kill ''en masse'' [[GuiltFreeExterminationWar without any guilt or consequences]]. Of course, the problem is that since the ''SW'' universe very much ''doesn't'' function with the same rules as the ''40K'' universe, the Imperials wind up massacring tons of InnocentAliens who did nothing wrong -- an act so heinous that it crosses the in-universe MoralEventHorizon, proves HumansAreTheRealMonsters, and ensures the Imperials will be HatedByAll in the ''SW'' galaxy.

** It's explained in Episode 17's Q&A segment that this trope is partially why the Imperium is so overtly skeptical and hostile towards the Republic; from their perspective, the existence of a galaxy-wide peace government where humans and aliens co-exist in harmony sounds '''way''' TooGoodToBeTrue. If this were a grimdark and dystopian setting where AliensAreBastards like the ''40K'' universe, the Imperials would be ProperlyParanoid for thinking this and the Republic would probably turn out to be a FalseUtopia where humans are an enslaved underclass. However, because the ''Star Wars'' universe functions as a more optimistic and romanticized SpaceOpera, the Imperials end up being totally wrong about the Republic (which is dominated and mostly controlled by humans) and their ImproperlyParanoid [[AbsoluteXenophobe absolute xenophobia]] drives them to commit heinous war crimes against countless InnocentAliens, thereby needlessly making enemies out of the entire ''SW'' galaxy.

** In Episode 17's Q&A, the author explains that this is partially why the Imperium treats the Republic with such overt hostility and suspicion; to the Imperials, the existence of a galactic peace government where humans and aliens get along sounds ''way'' TooGoodToBeTrue. If this were a grimdark, dystopian setting where AliensAreBastards like in ''40K'', they would be ProperlyParanoid for thinking this and the Republic would probably turn out to be a FalseUtopia where humans are an enslaved underclass. Unfortunately for the Imperials, they are now in the ''Star Wars'' universe, which more closely resembles a hopeful and idealistic SpaceOpera where the aliens act like regular people. Because of this, the Imperials end up being totally wrong about the Republic (which is dominated and mostly controlled by humans) and their ImproperlyParanoid xenophobia drives them to commit heinous war crimes against countless InnocentAliens, thereby needlessly making enemies out of the entire ''SW'' galaxy.

* AllForNothing: Everything that Anakin and the Bad Batch went through in Season 7 of ''The Clone Wars'' to rescue Echo and sneak aboard Trench's flagship to shut down the bomb on Anaxes turns out to have been all for nothing in Episode 8 when the Crimson Razors seize control of both Trench's flagship and the bomb, forcing the Republic to withdraw their forces from Anaxes, which is swiftly conquered by the Imperium.

* TimeSkip: Around halfway through Episode 10, the story jumps ahead to weeks after the Senate became gridlocked in response to the Imperium's invasion of the Axum system. This is done to show the fallout of the Imperial occupation of Axum. The Republic is shown to be facing a sudden refugee crisis caused by civilians who fled Axum before it fell. Meanwhile, the Imperials have had time to entrench themselves on Axum and start purging the planet's non-human population. Most of the Imperial invasion force has moved on since then, leaving behind only a token garrison to defend their newly conquered holdings, presenting the Jedi with the opportunity to launch a counter-invasion to retake Axum and force the Senate to break their weeks-long deadlock.

* CavalryRefusal: Subverted. During the mid-to-late stages of the Battle of Axum, Orion sent the entirety of Battlefleet Xek-Tek to provide naval reinforcements to the Imperials occupying Axum. However, as the battle goes increasingly sideways with the Republic counterattack armada massively outnumbering Battlefleet Xek-Tek and some Imperial capital ships even getting outright destroyed, Lord Admiral Sendurran decides that the battle is no longer worth it and is about to give the order for her battlefleet to retreat, abandoning the Imperials fighting on Axum. [[spoiler:However, she changes her mind at the last minute due to the arrival of [[TheCavalry even more Imperial naval reinforcements]] in the form of the Adeptus Mechanicus, the Tempered Hands, and a Rogue Trader guild. With these new fleets now supporting hers, Rollah is convinced to continue with her attempt to hold back the Republic armada and evacuate the Imperial garrison on Axum.]]

* RoaringRampageOfRevenge: After Palpatine successfully frames the Republic fleet for launching an unprovoked attack at FirstContact that destroyed an Imperial refugee ship and killed hundreds of thousands of innocent civilians, the Imperium is rightfully ''pissed off'' and spends the remainder of Season 1 on a prolonged revenge quest against the seemingly responsible parties. First, the Imperials promptly retaliate by massacring nearly a thousand Republic warships stationed at Pzob, unleashing ''every'' weapon in their arsenal and giving no quarter. Next, they forcefully invade Anaxes and Axum -- two of the Republic's most important founding worlds -- while killing everything that gets in their way. Then, after both worlds are conquered, the Imperials construct ''hundreds'' of death camps on Axum and waste no time slaughtering ''millions'' of Republic citizens over the course of weeks.
