->'''Cliffjumper:''' ''So, you're telling me that Megatron's a good guy and Optimus Prime is loonier than Straxus? Last week, I'd have told ya that you had a cracked cylinder. But... [[{{Understatement}} I've seen some]] '''[[{{Understatement}} crazy]]''' [[{{Understatement}} things lately]]. Dimension hopping, time travel, [[AlternateUniverse alternate realities]]... what I wouldn't give for a simple war with [[BlackAndWhiteMorality good guys and bad guys]]!''
->'''Sideswipe:''' ''CJ, if you want a simple battle between good and evil, you have one right '''here'''! [[MirrorUniverse The players are just in different places than you expect]].''

''The Decepticons wage their battles to destroy the evil forces of... the Autobots?''

In a strange AlternateUniverse, a librarian named Optronix, obsessed with power, cheated his way up through the ranks, then formed a band of similarly ruthlessly ambitious individuals. After reformatting himself into Optimus Prime, he led his new faction of Autobots into a successful conquest of Cybertron. Fortunately, a young mathematician by the name of Megatron, who had been forewarned by his equations that civil war was likely to happen, was able to form [[LaResistance his own band of rebels]], and led the Decepticons in a war to restore freedom to Cybertron.

After millions of years of fighting, the Transformers now stand poised to spread their battle to Earth, though they might find themselves entangled in the humans' own [[WorldWarIII civil wars]], as well as the machinations of the oppressively fascist United States. The Autobots, however, are more than ready to try and turn all of this to their advantage. Fortunately, the Decepticons have a newly-arrived dimensional traveler to help them, a [[Franchise/TransformersClassics strange Autobot by the name of Cliffjumper]] -- who brings news of other universes where the Autobots are good, the Decepticons are evil, and the planet is a god -- as well as a [[ScienceHero trio of friendly science interns]] and [[TheProfessor their boss]].

Unbeknownst to both sides, a third old faction of secret acolytes are plotting their own takeover of both Cybertron ''and'' Earth, involving [[AngelUnaware ancient beings on the run]] and potential multiversal consequences...

Just about every scifi universe that lasts long enough gets its own MirrorUniverse, and, as you might have guessed from the description, {{Transformers}} finally got theirs in April 2008. It started off as an April Fools joke gone horribly wrong (or right, depending on your POV), when the official Fanclub showed what they claimed to be a three-page preview of the upcoming [=BotCon=] comic, featuring a mirror universe story full of over-the-top bizarre character reversals and cheesy homages. The fans ate it up, thinking it was the best thing ever. The subsequent revelation that it wasn't actually the real comic didn't go over quite as well.

The real comic ended up being a more straightforward, serious, and clichéd take on the subject, though it still garnered a fair bit of positive fan attention. The later prose stories took a page from the reaction to the April Fools joke, and ended up being much more light-hearted and goofy, as well as engaging in more creative opposites than just "good/evil", as did the ''Around Cybertron'' side comic. The follow-up fanclub magazine serial comic, however, tended to follow the original comic in tone.

While the main SG continuity so far focuses on a [[TransformersGeneration1 mostly-Generation-1 mirror]], there are a few less-developed official SG versions of other continuities, with ''TransformersAnimated'' [[http://tfwiki.net/wiki/Sari_Sumdac_(SG_Animated) being]] [[http://tfwiki.net/wiki/Optimus_Prime_(SG_Animated) the most]] [[http://tfwiki.net/wiki/Bumblebee_(SG_Animated) prominent one]].

Has a [[Characters/TransformersShatteredGlass character sheet]] with the character-specific tropes. %%Please put tropes specific to individual characters there.
!!This series/universe provides examples of:
* AdaptationalVillainy: The Autobots, with the exception of the original universe's Cliffjumper, and the Witwicky family.
* AgonyBeam: The Autobots' Agonizing Rehabilitation Chambers.
* AliensStealCable: The Transformers use TV signals as research for their trip to Earth, but run into trouble when the fact that the signals are old has them thinking the humans are much less advanced than they actually are.
* BadassBookworm: Most of the Decepticons, and a few of the Autobots.
* BeardOfEvil: A few characters, notably Rodimus and Alpha Trion.
* {{Beware the Nice|Ones}}/[[BewareTheSillyOnes Silly Ones]]: The Decepticons are mostly nerdy, dorky, cheerful, friendly, and/or comedically eccentric, but when it's time [[LetsGetDangerous to get dangerous]] they can and will turn you into scrap. The Mayhem Suppression Squad is the best example, where they all have almost PluckyComicRelief personalities, yet are good enough to be considered the cavalry and easily turn the tide of a previously hopeless battle.
* BizarroUniverse: While the original comic depicts a straight-up MirrorUniverse, the prose and later comics tend more towards this.
* [[BunnyEarsLawyer Bunny Ears Soldier]]: The Decepticons, oh so much.
* ButHeSoundsHandsome: Punch, while enforcing his usual PaperThinDisguise.
* CardCarryingVillain: The SG Autobots identify as the "[[https://www.facebook.com/pages/Evil-Autobots/281770265204279?ref=ts&fref=ts Evil Autobots]]" on {{Facebook}}. A difference needs to spelled out between them and the Good Autobots, but why this way?
* TheCavalry: Deliberately {{invoked|Trope}} by Soundwave at one point when he sent in the Mayhem Suppression Squad.
* CharacterBlog: Ravage has his own [[http://twitter.com/ravagekitteh Twitter]] ("Yatter", in-universe), [[http://www.facebook.com/people/Ravage-Sg/1178801320 Facebook]], and [[http://www.formspring.me/sgravage Formspring]] pages.
** Starscream also has his own [[http://twitter.com/sgstarscream Twitter]] and [[http://www.formspring.me/sgstarscream Formspring]] pages; but these aren't as 'official' as Ravage's is (and also a bit less active). Still entertaining, and some of his answers are hilarious.
* CrapsackWorld: Cybertron is a planet-sized junkyard with big patches of it on fire, newborn Transformers are granted their [[OurSoulsAreDifferent embers]] by a malevolent computer, there's no Matrix, the Earth suffered through WorldWarIII, the United States is an oppressive, power-hungry fascist regime, and that's just for starters.
* {{Crossover}}: The US President, Vice-President, and Secretary of Defense are mirrorverse versions of {{GI Joe}} characters, and Soundwave is an avowed Cold Slither fan. ''Blitzing Bop'' alludes to a supervillain by the name of [[ComicBook/SpiderMan Arachno-Lord.]]
* DeathTrap: Ricochet threatens Megatron with not one, but ''five'' of these at one point. In another story, Blurr, Cliffjumper, Rodimus, and Sideswipe find themselves stuck in a creepy temple chock full of these.
* DeepCoverAgent: Alpha Trion has a number of these in both factions. [[spoiler:And the Underbase also has its own agents in each faction.]]
* EnemyMine: Autobots Rodimus & Blurr and Decepticons Cliffjumper & Sideswipe are forced to team up against mutants and [[spoiler: Grimlock]].
* EngineeredPublicConfession: [[spoiler:Soundwave]] pulls one of these on [[spoiler:Blaster]] to get Thunderwing to arrest him.
* EvenEvilHasStandards: While the Autobots don't seem to have very ''high'' standards, even they couldn't tolerate [[MadScientist Wheeljack]] for that long. Subverted in that they take him back after he arrives with the dysfunctional Dinobots.
* EvilTwin: And good twins. And WTF twins.
** Interestingly, the characters tend to have the color schemes of their G1 equivalents' Evil (or Good) Counterparts. The Technobots and Terrorcons, for instance.
** Also interestingly, there seem to be counterparts to characters from many different continuities. A heroic [[TransformersArmada Demolishor]] and a villainous [[Anime/TransformersRobotsInDisguise Side Burn]] both show up despite neither character having any roots in G1. [[spoiler:Turns out it's because they're bizarre non-Cybertronian agents of the Underbase.]]
* {{Expy}}: This may be a simple side-effect of their flipped personalities, but Starscream and Cyclonus appear to be based on each other's G1 counterparts.
* FiveManBand: The components of Nexus Prime fit this surprisingly well, considering each character was developed/introduced to the team individually.
** TheHero: Skyfall is the one who initiates the Nexus Prime quest to begin with and provides the major motivation for keeping it going, and he's the most laid-back and "normal" of the group.
** TheLancer: Landquake is a Decepticon to Skyfall's Autobot, and dour, duty-bound, distrusting, and pragmatic versus Skyfall's more emotional, impulsive, and idealistic attitudes. Yet he provides a lot of emotional support to Skyfall and serves as the ''de facto'' second-in-command [[spoiler:when Skyfall is killed]]. Not that he especially ''likes'' ever being in command, mind; he only does it when he feels someone has to.
** TheSmartGuy: [[spoiler:Heatwave, on account of being a brilliant engineer and {{technopath}}.]]
** TheBigGuy: Topspin, who served as [[spoiler:Alpha Trion's]] [[TheDragon Dragon]] at one point, and is definitely willing to dish out destruction via telepathically ripping out people's sparks, if you order him to or he gets pissed enough.
** TheChick: Breakaway, who serves as the team's medic due to his healing power, is ever optimistic and trusting, and tries to provide emotional support and pep talk anyone who's feeling down or discouraged. He even ends up as a DistressedDude at one point.
* IntercontinuityCrossover
** [[spoiler:Alpha Trion spent some time in the ''TransformersTransTech'' universe.]]
** Cliffjumper is from ''Franchise/TransformersClassics''.
** ''Shattered Glass Animated''. That is all.
** [[spoiler: The Earth of the Classicsverse is now in the Shatteredverse]].
* KentBrockmanNews: The ShowWithinAShow side comic ''Around Cybertron''.
* KillSat: The United States has one.
* LampshadedTrope: This happens fairly frequently, usually via ''Generation 1'' Cliffjumper's complaints about his new home universe.
* LiteralSplitPersonality: Nexus Prime.
* MadScientist: The Autobots have several (with Wheeljack in particular being almost the perfect epitome of the trope). The Decepticons have several ''friendly'' ones.
* MerchandiseDriven: There's only a small number of official "Shattered Glass" toys available, so the various authors took to officially "repurposing" figures from other Transformers toylines to represent various Shattered characters. Several fans have also taken it upon themselves to hand-craft the official redecos for other characters.
* MirrorUniverse
* MonumentalDamage: In "Eye in the Sky", Rodimus hijacks the USA's KillSat and uses it to hold the world hostage to his demands. To show his threat is serious, he uses his control of the satellite to destroy a [[http://tfwiki.net/wiki/Image:Statue_of_Liberty_SG.gif sword-holding Statue of Liberty]].
* MoodWhiplash: Between the DarkerAndEdgier comics and the much more light-hearted prose stories, which are nevertheless all in the same storyline.
* MoreDakka: The Autobots are big fans of this. The reason the ''Ark's'' launch was delayed was due to the sheer amount of weapons Optimus Prime ordered installed, thereby making the ship heavier and vulnerable to Megatron's surprise assault. Optimus' main weapon is also capable of putting a lot of firepower into the air very quickly.
* MythologyGag: By the hundreds. One of the more comical ones is Blaster's Scrounge minions, who say "This is my special arm! There are many like it but this one is mine!" This is a reference to the original Scrounge, who was infamous for his claim that his special arm is one of a kind.
** In the "Shattered Expectations" mini-comic, the main characters are Jazz, Goldbug (evil Bumblebee), Grimlock, and Starscream - the Classic Pretenders from G1 continuity.
** There are also all of the color flips. For instance, the Technobots have the Terrorcons' colors and vice versa. And then there's Dirge, which is a ''quadruple'' color-switching toy homage.
** The Autobots' warship, the ''Ark,'' crashes into the ocean. The Decepticons' ''Nemesis'' crashes into the side of a mountain - the opposite of how it went down in ''WesternAnimation/TheTransformers''.
* NoCelebritiesWereHarmed: Jazz is MrT, Rodimus is [[WelcomeBackKotter Vinnie Barbarino]], Thunderwing is [[Franchise/{{Dragnet}} Jack Webb]]...
* NonindicativeName: Happens frequently due to the personality reversals. Sometimes it's [[JustifiedTrope given an excuse]], often it isn't.
* NoOSHACompliance: Autobot HQ, big-time.
-->'''Rodimus''': We got a fraggin' pit full of fire in the middle of the main room, we gots rusty spikes coming outta the ground, we gots gapin' chasms every other meter… who puts that stuff there?
** Justifiable, as Optimus is a certifiable loon.
* ReferenceOverdosed: The prose stories have insane quantities of references to both other Transformers series and non-Transformers concepts, with [[TransformersFilmSeries one character who talks entirely in real world song lyrics]] probably being the most over-the-top example.
* RunningTheAsylum: Even more than with other modern incarnations of ''Transformers,'' it's very difficult to find someone who worked on ''Shattered Glass'' and ''isn't'' a PromotedFanboy.
* ScienceHero: Professor Arkeville and his three equally human interns, who generally make up for their squishiness with ingenuity and gadgetry. Also AbsentMindedProfessor Starscream, who's more likely to science his way out of a situation than outright fight.
* ShipTease: In "Transhuman" Rick finally admits his crush on Sephie, and while she doesn't outright reciprocate, she doesn't reject him either. She instead seems kind of flattered/pleased, and later energetically defends his honor when the Autobots insult him in a battle.
* ShoutOut: During the sequence when Ricochet is explaining in great detail to Megatron the [[NoKillLikeOverkill five death traps he has ready]], one could insert the voice of Series/{{Mythbusters}}'s Adam Savage in one of his fake accent moments, and it would fit remarkably well. He even directly quotes the group to boot.
** Soundwave [[AndIMustScream has no mouth]]...yet he must [[ThePowerOfRock rock]].
* SkewedPriorities: After spending much of "Transhuman" bravely battling against robots in life-or-death situations with no problems, Sephie finally {{Heroic BSOD}}s at the end of a battle... upon finding out she's been fired. [[spoiler:And by a boss which she had just been battling against because he betrayed her and the Decepticons.]] Rick even gripes at her about it.
* StrawmanNewsMedia: The Autobot Broadcasting Network is a blend of Types 2 & 4.
* ThereAreNoTherapists: Averted for the Decepticons, who have several psychologists and run "group therapy" sessions frequently. Granted, they're still extremely eccentric, but they seem happy and well-adjusted otherwise.
* TheyCalledMeMad: Wheeljack, hence why he was ''[[EvenEvilHasStandards kicked out of the Autobots.]]''
-->"I'm not crazy! Everyone else is just blind to my genius! I'll show you I'm not crazy! I’ll show every last one of them I'm not a foaming-mad megalomaniac with delusions of grandeur! As soon as I perfect my atomic supermutant alloygators, you'll all see I wasn't crazy!!!"
* TwoLinesNoWaiting: "Do Over" has this plot structure. Arguably the overall series as well, between the prose storyline and the magazine serial storyline.
* VerbalTic: A number of the Transformers have one, notably Grimlock, Goldbug, and Nightbeat.
* VisualPun: Quite a bit of the fanart shows the Autobots--particularly Optimus-- [[http://inker-guy.deviantart.com/art/Within-Shattered-War-Colors-84045926 with their windshields noticeably cracked]] as a nod to the setting's title.
* WhatTheHellIsThatAccent: Many of the Transformers have bizarre accents that only vaguely match any real ones. [[http://tfwiki.net/wiki/Talk:Blaster_(SG) Even the author admits as much]].
* WorldWarIII: The UsefulNotes/ColdWar escalated into this.
