** Chief Edge. He is the Tetrad member most obsessed with revenge on the Thirteen, refusing to hear them out or entertain the idea of them being anything other than innocent (guilty), and continuing to fight when the other Quintessons make peace before Quintessa makes him stop.

* AdaptationalSpeciesChange: Quintessa is a Quintesson here, while she has no confirmed species in the films, implied to be either a [[Film/TransformersAgeOfExtinction Creator]].

* TakingYouWith: [[spoiler:Edge refuses to surrender or give up his vendetta against the Thirteen, so he activates the Prosecutor network's self-destruct protocol to kill as many Cybertronians as possible and destroy Cybertron, uncaring that he will die as well.]]

* AdaptationalSpeciesChange: Quintessa is a Quintesson here, while she has no confirmed species in the films, implied to be either a [[Film/TransformersAgeOfExtinction Creator]], or something else.

* StaffOfAuthority: Quintus created the Staff of Quintessence for Quintessa to wield as her symbol of leadership among the Quintessons. Cerebro later modified it with the ability to drain the life force of celestial bodies.

** Quintessa has a pet three-headed dragon that she refers to as her "Guardian Knight", a reference to Dragonstorm, the combined form of the Guardian Knights from ''The Last Knight''.

* HiveMind: The Prosecutors all share a mental link between each other, which is why they fight so effectively in swarms.

* LastDitchMove: When it seems like Edge has all but lost, [[spoiler:he activates the Prosecutor network self-destruct, in an effort to destroy as many Cybertronians as possible and Cybertron itself]].

* WoundThatWillNotHeal: Solus designed the Requiem Blaster to be not only the most powerful weapon, but a weapon capable of damaging ''[[CosmicEntity Unicron]]''. That kind of firepower makes any damage caused by it permanent and impossible to heal. Solus even tried transferring her Spark into a blank protoform to get a new body, and her wounds just reappeared once the transfer was complete.

* KickTheMoralityPet: Despite considering Quintessa family, Edge blames her for possibly angering the Thirteen when the Quintessons are sent into Unspace.

* StaffOfAuthority: Quintus created the Staff of Quintessence for Quintessa to wield as her symbol of leadership among the Quintessons. She later modified it with the ability to drain the life force of celestial bodies.

* WoundThatWillNotHeal: Solus designed the Requiem Blaster as a weapon able to damage ''[[CosmicEntity Unicron]]'', so any damage caused by it is permanent and impossible to heal. Solus even tried transferring her Spark into a blank protoform to get a new body, and the damage just reappeared once the transfer was complete.

-->'''Klementia:''' Keep this up, and your innocence will be proven. ("Innocent", means Guilty)
-->'''Cerebro:''' Would you like to know how fast Cosmic Rust can destroy metal?

** It is mentioned that the very first Quintesson created before the Tetrad was known only as "It". "It" was an ancient Quintesson that appeared in the G1 episode "Five Faces of Darkness".

** Vector has the Blades of Time, and [[DimensionalCutter Rhisling]], his sword from ''Anime/TransformersCybertron''.

** Micronus has the Chimera Stone. Since he wields infinite energy and mostly powers others, has no weapon.

** Liege Maximo has the Liegian Darts. Instead of a weapon, he had Solus incorporate them into his fingers.

** Alpha Trion has the Quill and the Covenant of Primus. As his role is to observe and record, he has no weapon.

** Prima has the Matrix of Leadership, which was built into the Star Saber, turning it into a LaserBlade.
** Vector has the Blades of Time, and Rhisling, his sword from ''Anime/TransformersCybertron''.

** Solus has her Forgehammer. Since the Forgehammer is already so powerful, it doubles as her weapon.

** Nexus has the Enigma of Combination, which he uses on his sword, Cyber Caliber, to split into the dual swords Chaos Edge and Omni Saber.

** Amalgamous has the Transformation Cog, and a MorphWeapon called the Scythe.
** Quintus has the Emberstone. Since he mostly oversaw Cybertronian creation, he felt no need for a weapon.

** Megatronus has the Requiem Blaster. Since he wasn't given an artifact, Solus built the Blaster as the most powerful weapon.

''Transformers: Shadows of the Past'' is a Franchise/{{Transformers}} fanfic by Master_Seven.

In a departure from most Transformers media, it combines the G1 cartoon's origin story with the Primus origin story, depicting the Quintessons as creations of Quintus Prime made to help the Thirteen Primes in the development of early Cybetronians, before being abandoned under mysterious circumstances. Angry and embittered, the Quintessons, led by the Quintesson Tetrad ([[Film/TransformersTheLastKnight Quintessa]], [[WesternAnimation/TransformersCyberverse Judge Klementia, Dr. Cerebro, and Chief Edge]][[note]]Adaptations of the ''Cyberverse'' Judge, Scientist, and an individual Prosecutor[[/note]]) search the universe for their creators, so they may have their {{revenge}}.

* MythologyGag: The fic contains a mishmash of elements from various Transformers series, so references abound.

* AdaptationalOriginConnection: A straight and inverted exammple. Most Transformers media removes the Quintessons as their creators in favour of Primus, while here, they're both responsible.

* AdaptationalJerkass: Liege Maximo is somehow even worse than usual. Along with his usual crimes, he also sent the Quintesson Homeworld into Unspace out of spite towards Quintus, resulting in the Quintessons thinking they were abandoned, broke the Star Saber because Prima valued it so much, and generally screws over everyone and everything [[ForTheEvulz just because he can]]. [[spoiler:While he's always been a dick, this newfound assholery is the result of Unicron poisoning Liege's mind.]]

* AmbiguousSituation: While the Thirteen recognize Optimus as the Thirteenth Prime, they all note something about him is just off enough that they're not fully sure if he really is him. Liege Maximo refuses to acknowledge Optimus and says the Thirteenth is dead, but given [[ConsummateLiar it's Liege Maximo saying so]], his word is ignored.

* BigBadEnsemble: There are three separate forces at work in the story. There is the Tetrad, who want to punish and kill the Thirteen, Liege Maximo, who's against everyone, including the Thirteen, [[spoiler:and Unicron, whose influencing Liege's worst action and trying to bring about the death of Cybertron so he can return to destroy the universe unopposed]].

* GreaterScopeVillain: [[spoiler:Unicron is responsible for the whole story, having poisoned Liege Maximo's mind when the Thirteen defeated him so he could cause the eventual downfall of Cybertron.]]

* {{Reincarnation}}: During the Age of the Thirteen, Liege Maximo threw the Thirteenth Prime into the Well of the [=AllSpark=], and it's noted he was reincarnated. It's kept ambiguous whether the Thirteenth became Optimus Prime.

** Liege Maximo is the most evil member of the Thirteen, constantly doing morally questionable or utterly reprehensible acts, and [[spoiler:even before his mind was poisoned by Unicron]], he wouldn't hesitate to do something the other Thirteen considered wrong.

** Prima has the Matrix of Leadership, which Solus built into the Star Saber, turning it into a LaserBlade.

* AmbiguousSituation: While the Thirteen recognize Optimus as the Thirteenth Prime, they each note something about him is just off enough that they're not fully sure if he really is the Thirteenth. Liege Maximo refuses to acknowledge Optimus as the Thirteenth and says he's dead, but given [[ConsummateLiar it's Liege Maximo saying so]], his word is ignored.

** Prima has the Matrix of Leadership, which was crafted into the Star Saber, turning it into a LaserBlade.

** Alpha Trion has the Quill and the Covenant of Primus. As a chronicler, he had no need to fight.
** Solus has her Forgehammer. Since her Forgehammer is already so powerful, it doubles as her weapon.
** Micronus has the Chimera Stone. Like Solus, he doesn't have a weapon, since he wields infinite energy, and mostly powers others.
** Alchemist has the Lenses. Unlike his siblings, he didn't request a weapon.

** Onyx has the Triptych Mask. Like Alchemist, he didn't request a weapon.

** Quintus has the Emberstone. Since he mostly oversaw the Quintessons, he felt no need for a weapon.

** Megatronus has the Requiem Blaster. As the most powerful Prime, he needed no weapon.

* SparedByTheAdaptation: Solus Prime isn't killed by Megatronus here, being merely wounded by the Requiem Blaster [[CrazyPrepared thanks to a failsafe she installed in all her creations]] in case they were ever against the Thirteen.

** Alpha Trion has the Quill and the Covenant of Primus.

** X has .

** is known as the Prime of .
