Yeah, there's a whole slew of them. LET'S GET THEM ALL!

[[folder:Cybertronian Empire]]

!!Liege Maximo

One of the Thirteen Original Transformers, created as a force of evil to keep the balance with his good counterpart, Prima. He's implied to be the founder of the Decepticons, and he left Cybertron with several followers to create a Cybertronian Empire that {{Terraform}}s conquered planets.
* AdaptationalWimp: When your original incarnation is the head of a massive empire and ludicrously huge... anything else is going to be something of a let down. His modern day incarnations are regular-sized, and slightly less harmful in their approach.
* AscendToAHigherPlaneOfExistence: According to the non-cannon but Furman-written ''Allingment'', the Liege's goal was to become a god like Primus and Unicron. Pretty much no other version of him has displayed this trait, though (aside from a nod in the Facebook ''Ask Vector Prime'' page).
* AttackOfTheFiftyFootWhatever: Cybertronians are already big by human standards. This guy is somewhere upward of a hundred feet and counting.
* FaceHeelTurn: According to ''Ask Vector Prime'', at least one version of him (from the "Rhythms of Darkness" timeline) turned good when Unicron killed that reality's Primus, and the Liege died doing in the destroyer.
* GreaterScopeVillain: His G2 incarnation was implied to be Megatron's ancestor.
* ManBehindTheMan: To Jhiaxus, and the Cybertronian Empire as a whole.
* ManipulativeBastard: All his ''Power of the Primes'' abilities revolve around the Liege being a silver tonged devil.
* ObviouslyEvil: Giant, deep red eyes, covered in spikes, burning stump where his left hand should be. Yup, he's pretty evil.
* OrcusOnHisThrone: Never really did anything of note before the G2 comics ended.
* ShoutOut: His artwork in ''The Covenant of Primus'' bears a resemblance to ComicBook/{{Loki}}.
* ToylessToylineCharacter: Does not receive any toys until the ''Power of the Primes'' toyline.
* YouDontLookLikeYou: He finally received a toy in ''Power of the Primes''. Said toy is a tiny Headmaster-like thing that doesn't resemble the Liege ''at all''. Even the shell it comes with looks more like Skullgrin.

!!!Function: Air Space Commander
-->"The only thing I fear... is myself."

The general of the Liege Maximo's Cybertronian Empire in the G2 comics. Alternatively, Jhiaxus was a crew member on the ''Ark-1'' and serves as Nova Prime's pet mad scientist; his obsession with forcing Cybertronian evolution has led him to introduce gender to the Transformer race, modify his own body into a form resembling [[Film/TransformersFilmSeries that of Bayformer Starscream]], and the creation of both [[CombiningMecha gestalt]] and [[PintSizedPowerhouse Micromaster technology]].
* ArcVillain: In ''Regeneration One'', he's the villain for the last full arc.
* TheBerserker: His G2 incarnation tries to repress his older, more brutal nature. When everything goes to crap for him in the finale, he lets loose, and beats Optimus within an inch of his life. Only the fact that the Swarm shows up stops him from crushing Optimus' head.
* BigBad: He's the main villain of the G2 comics. However, in terms of actual scope, he's barely TheHeavy.
* CanisLatinicus / PunnyName / TakeThat: Well aware that the ''ComicBook/TransformersGeneration2'' series would probably be cancelled before it ran very many issues due to unrealistic sales expectations, Simon Furman named him after the pun "Gee, axe us!"
* DarkAndTroubledPast: He is forced to confront his in Generation 2 issue #3. He was once a violent sadist, and has since cultivated a calm and reasonable personality in an effort to convince himself that he is a moral person. It turns out that's just a facade, and that he's still as bad as he always was. Naturally instead of admitting this, he's determined to kill Prime and the Autobots so they can't remind him of the truth of who he is.
* DragonAscendant: Could be considered TheDragon to Nemesis Prime, and becomes the BigBad in RID. When Dark Cybertron begins he willingly [[DemotedToDragon demotes himself]] to serve his pupil, Shockwave.
* TheEvilGenius: To Nova Prime's BigBad in the IDW comics.
* EvilMentor: To Shockwave, again from IDW.
** SurpassedTheTeacher: By Dark Cybertron, he admits that Shockwave is his superior.
* EvilutionaryBiologist: Or the closest equivalent for a race of mechanical lifeforms, at any rate. [[ProfessorGuineaPig He's even willing to experiment on himself]], [[{{Gonk}} resulting in a body that has far more in common with the Transformer designs of the recent movies than Generation 1.]]
* GoneHorriblyWrong: IDW Jhiaxus had a ''very'' poor track record when it came to his experiments. The end result of his attempt to introduce gender to a genderless species, Arcee, became a psychotic and violent mass-murderer obsessed with tracking him down and murdering him as slowly and painfully as possible; and Monstructor, his effort at producing a gestalt, is a nigh-indestructible and vicious killing machine, about the only one that didn't go wrong is his space bridge invention.
** Actually subverted on Monstructor's insanity. According to [[ComicBook/TheTransformersRobotsInDisguise RID issue 7]], Jhiaxus doesn't consider it a weakness.
* MadScientist: IDW Jhiaxus experimented on Cybertronians without their consent.
* ToylessToylineCharacter: Until 2014, when he got a toy in ''Generations''. Which doesn't look much like him.
* TheUndead: Like all Dead Universe Transformers.

* MauveShirt
* MeaningfulName: Meta example; he shows the mindset of the Imperials to the reader.
* RoboFamily: All Imperials are related to some Autobot or Decepticon via "budding", but he's one of the few ones whose ancestor is revealed, the Combaticon leader Onslaught.

* {{Foil}}: To Jhiaxus. He keeps his cool while Jhiaxus is slowly losing it throughout the comic.
* LeanAndMean: Regeneration One has him considerably thinner and sleeker looking.
* ScrewThisImOuttaHere: Justified example. He leaves because Jhiaxus is out of control and he needs to inform the Liege Maximo.

[[folder: Humans]]

!! Spike Witwicky
->'''Voiced by''': Creator/CoreyBurton

The Autobots' iconic human friend.
* ABoyAndHisX: A boy and his robotic best friend. And that would be Bumblebee.
* CasanovaWannabe: In his younger years, hitting on nearly every girl he meets and failing. And that's even after meeting Carly.

* EmpoweredBadassNormal: After becoming Fortress Maximus, he's even more formidable than when he was just a normal human.
* LegacyCharacter: To Galen as Fortress Maximus in the Marvel comics (Spike was the first and only to become him in the cartoon) [[spoiler:and Becomes Circuit Smasher in the Regeneration One series.]]

!! Sparkplug Witwicky
->'''Voiced by''': Chris Latta

Father of Spike and Buster.
* BadassGrandpa: He's a middle-aged man who is still pretty good at helping the Autobots fight the Decepticons.
* BadassNormal: While just a normal guy, he's still pretty useful and can even help Ratchet and Wheeljack with their tinkering.
* ChuckCunninghamSyndrome: Completely disappears after season 2. Although, it is entirely possible that he died of old age in the twenty year gap between season 2 and TheMovie.
** He was in the script for "Five Faces of Darkness, Part 1", on the Earth Defense Command shuttle with Blaster and Outback going to Carbombya to investigate Decepticon activity. His single line in the script was given to Blaster in the final episode.
* DependingOnTheWriter: In the Marvel comics, his first name was intended to be Stanislas Piotr (hence the name of his service shop being "S. Witwicky Auto Repairs & Tow Service"); though issue 4 has his name being William and issue 31 it's Irving. In the IDW comics it's Daniel.
* ThePatriarch: He is Spike Witwicky's father and is well respected by the Autobots.

->'''Voiced by''': Michael Horton

Spike's wheelchair-bound best friend.

* ChuckCunninghamSyndrome: He stops appearing halfway through season two. Though he does make a two second cameo appearance (with his back to the viewer) in the Japanese-exclusive special, "Scramble City." Concept art of an adult Chip was created for ''The Headmasters'', but he never appeared.
* HandicappedBadass: He may be in a wheelchair, but he's still as useful an ally to the Autobots as Spike.
* NerdGlasses: He wears glasses and is kind of nerdy.

!! Carly
->'''Voiced by''': Arlene Banas

Spike's girlfriend and future wife.

* OnlyOneName: While it would obviously be Witwicky after she married Spike, her maiden name remains unknown.

!! Daniel Witwicky

* JumpedAtTheCall: He's always happy to get a chance to help the Autobots.

!! Doctor Arkeville
->'''Voiced by''': Creator/CaseyKasem

A MadScientist ally of Megatron who specializes in mind-control in the Season 1 Three-Parter ''The Ultimate Doom,'' in a bid to become the ruler of Earth once Megatron has harvested all its energy.
* {{Cyborg}}: The top of his scalp and his left hand are metallic-mechanical replacements of biological ones. "Countdown to Extinction" takes it further by having most of his body replaced with robotics except for half his face and part of his chest and right arm.
* EvenEvilHasStandards: Even though Doctor Arkeville happily ''enslaves'' human beings by the hundreds with his [[BrownNote hyno-chip implants]], he draws the line at cold-blooded murder, and is visibly ''horrified'' by Megatron's callous proposal of leaving them to die in favor of gathering energy, showing clear concern for the safety and welfare of his slaves over his conquest of Earth.
* HollywoodCyborg: The top of his scalp and his left hand are metallic-mechanical replacement of biological ones.
* ObviouslyEvil: Well, the word '''Evil''' is in his name, after all.
* TheQuisling: He allies himself with the Decepticons.
* WhatHappenedToTheMouse: Never shows up again after being left on Cybertron as an immobile cyborg in "Countdown to Extinction". Though supplementary material in the Japanese G1 cartoon continuity revealed that he's quite mobile and is back on Earth.

* FieryRedhead
* KilledOffForReal: She is killed off in ''Regeneration One''.

!! Marissa Faireborn
->'''Voiced by''': Susan Blu

The Autobots' main contact/ally in the Earth Defense Command. [[IntercontinuityCrossover Daughter of]] [[Franchise/GIJoe Flint and Lady Jaye]]. In her younger years, she was ironically a vigilante opposing the EDC (at the time, the EDC was anti-Transformer), and was a Kiss Player, a girl with the ability to kiss a Transformer to FusionDance with it and dramatically boost its powers and share her knowledge and skills.
* ActionGirl: She's an occasional ally to the Autobots.
* BroughtDownToNormal: After the events of ''Kiss Players'', she presumably lost her ability to fuse with a Transformer.

* EvenTheGirlsWantHer: Shaoshao Li fell in LoveAtFirstSight with her.
* FieryRedhead: She has red hair and is temperamental.

!!Josie Beller/Circuit Breaker
Josie was a brilliant scientist who was crippled in an attack by the Decepticon Shockwave. Vowing revenge, but transferring her hatred to '''all''' Transformers, she designed a cybernetic suit that allows her to walk again, fly, and channel electricity. Only appears in the comics.
* AntiVillain: Besides her vendetta against Transformers, her main motivation is to help and protect humans, repeatedly risking her life and taking injuries to save innocent bystanders.
* TheCameo: Briefly appears in ''ComicBook/SecretWarsII'', where she has a chat with [[RealityWarper The Beyonder]]. He found her very interesting and amusing, so he cancelled his plan to brainwash the entire universe. He reasoned that turning people into mindless slaves would deprive him of such excellent entertainment. In essence, she saved the universe without even realizing it.
* ClingyCostume: Since she needs it to walk, she's never without her costume.
* {{Determinator}}: She designed and constructed her suit while she only had the use of ''one arm''.
* DidYouJustPunchOutCthulhu: She once pumped out enough electricity to make ''Unicron'' scream in pain, distracting him long enough for Optimus Prime to defeat him with The Matrix of Leadership.
** BrokeYourArmPunchingOutCthulhu: The strain of this feat put her in a coma.
* DisabilitySuperpower: She's crippled, but wears a suit that gives her amazing powers.
* DisabledHottie: She can no longer move on her own and is very attractive.

* MsFanservice[=/=]{{Stripperific}}: She's naked under her cybernetic suit, which looks like thin strips of strategically placed tinfoil.
* ShockAndAwe: Her name "Circuit Breaker" is well put, as she can electrocute Transformers until they short circuit and burn.
* VanHelsingHateCrimes: It doesn't matter how much other humans vouch for the Autobots, she doesn't care.
* VaporWear: The amount of skin her suit leaves exposed makes it clear she's not wearing anything underneath.

!! Atari Hitotonari
When her parents were killed in a Transformer-related accident, she was left despondent, resentful of the giant robots, and wishing to die. But when she was discovered to be a Kiss Player, perhaps the most powerful Kiss Player in existence, she was forcibly drafted into the Earth Defense Command, partnered with a man-made Transformer called Autorooper Ne-04, and ordered to help defend the world against the threat of Legion, an army of monstrous creatures formed from Galvatron.
* BewareTheNiceOnes: When she is pushed, she pushes back, hard. Her feats include tearing a girl who had murdered her friend limb-from-limb, and [[spoiler: throwing Galvatron into space.]]
* BigEater: Often gorges herself on donuts and other sweets.
* BroughtDownToNormal
* ButtMonkey: She's taken some incredible humiliation, like Starscream taking over her body and going on a rampage with her panties exposed.
* CharacterDevelopment: Her story from start to finish consisted of her learning to overcome her shyness and fears, accepting her duty, and understanding the importance of truly living.
* ChronicHeroSyndrome: Despite her reluctance to fight and desire to be ordinary, she cannot stand to see anyone in pain.
* DeathSeeker: At first.
* EvenTheGirlsWantHer: Another Kiss Player named [[PsychoLesbian Ringo Chikuma]] stalked her and gave her several {{Forceful Kiss}}es.
* IdolSinger: After losing her Kiss Player powers, she briefly formed a singing group with Marissa Faireborn, Shaoshao Li, and others to travel the world and promote improved relations between humans and Transformers.

* {{Meganekko}}
* PaintItBlack: While she was possessed by Starscream, her outfit turned black.
* ShrinkingViolet
* SurvivorGuilt
* TouchedByVorlons: Her Kiss Player powers came from [[spoiler: exposure to fragments of Galvatron's body infused with Unicron's energy. She lost them when the fragments were reabsorbed.]]
* UnwittingPawn: [[spoiler: EDC Commander Hitoshizuku Amaō manipulated nearly her entire life, including the deaths of her parents and her gaining Kiss Player powers, so she could be used as the perfect host body for Hitoshizuku's dead daughter. Fortunately, Atari, Marissa, Shaoshao, and their partners foiled this plot and defeated her.]]
** [[spoiler: The Sparkbots nearly tricked her, Marissa, and Shaoshao into summoning Unicron. Primus had to personally intervene to prevent this.]]

!!Shaoshao Li
Marissa Faireborn's childhood friend, who became a Kiss Player and enlisted in Earth Defense Command to fight Legion. She was Autorooper Ne-04's original partner, but went missing for a while and resurfaced with Hot Rod as her partner.
* ActionGirl: Knows martial arts and weapons like tonfas.
* BroughtDownToNormal
* CharacterDevelopment: Learned to be nicer and more accepting. Eventually got over her obsession with Marissa and gave her and Optimus Prime her blessing.
* ChineseGirl
* DualTonfas
* GreenEyedMonster[=/=]TheResenter: Hated Optimus Prime for "stealing" Marissa from her. Hated Atari for being more powerful than her (Shaoshao was considered the most powerful Kiss Player before Atari came along).
* FantasticRacism: Hates the Transformers and resents having to partner with them. She reluctantly admits that she enjoys kissing Hot Rod.
* IdolSinger: After losing her Kiss Player powers, she briefly formed a singing group with Marissa Faireborn, Atari Hitotonari, and others to travel the world and promote improved relations between humans and Transformers.
* InterspeciesRomance: With Hot Rod. Though she never truly loved him.
* {{Jerkass}} -> JerkWithAHeartOfGold
* LoveAtFirstSight: Loved Marissa from the moment they met as children.
* MurderTheHypotenuse: Tried to goad Hot Rod into killing Optimus Prime. Hot Rod nearly went through with it because he was under the impression that Prime was an imposter.
* {{Qipao}}: One of her iconic outfits.
* SlaveCollar: Ever since she was a child, she's worn a metal collar that's secured with a padlock and has "Fortune" engraved on it. She never removes it and it is not affected by TheNudifier. She is not and has never been a slave, but she refuses to explain its purpose or origin.
* TouchedByVorlons: Her Kiss Player powers came from [[spoiler: exposure to fragments of Galvatron's body infused with Unicron's energy. She lost them when the fragments were reabsorbed.]]
* UnluckyChildhoodFriend: Unfortunately for her, Marissa only had eyes for Optimus, and is straight.
* UnwittingPawn: [[spoiler: The Sparkbots nearly tricked her, Atari, and Marissa into summoning Unicron. Primus had to personally intervene to prevent this.]]

!! Ringo Chikuma
A Kiss Player partnered with the man-made Transformer Autorooper Ne-01 who happily enlisted in the EDC for the opportunity to fight and slaughter. When Atari Hitotonari was forced to join, Ringo stalked, sexually harassed, and abused her. Atari was too frightened and unassertive to resist, essentially making her Ringo's sex slave behind closed doors. When Atari tried to report her, she was ignored. When Ringo made the mistake of callously gunning down one of Atari's friends right in front of her, Atari finally snapped and tore her limb-from-limb.
* AxCrazy
* BloodKnight
* DomesticAbuser
* DrivesLikeCrazy
* ForcefulKiss
* GirlishPigtails
* HairDecorations: Heart-shaped hairpins.
* HemoErotic
* InsistentTerminology: Ordered Atari to call her "Princess Ringo".
* KarmicDeath
* PintSizedPowerhouse
* PsychoLesbian
* TouchedByVorlons: Her Kiss Player powers came from [[spoiler: exposure to fragments of Galvatron's body infused with Unicron's energy.]]
* [[YouGottaHaveBlueHair You Gotta Have Pink Hair]]

!! Abdul Fakkadi
->'''Voiced by''': Philip L. Clarke

The self-professed Supreme Military Commander, President-for-Life, and King of Kings of the [[PeoplesRepublicOfTyranny Socialist Democratic Federated Republic of Carbombya]]. A corrupt and greedy leader who is often willing to make deals with the Decepticons to further his goals. The creation of this incredibly offensive Middle-Eastern stereotype caused Creator/CaseyKasem (who is of Lebanese descent) to quit the show in disgust.
* ChestOfMedals: He has a lot of medals on his body.
* TheGeneralissimo: He's a military leader of a third-world country he apparently rules with an iron fist.
* {{Greed}}: He's very obsessed with gold.
* {{Jerkass}}: Not a nice guy at all.
* NoCelebritiesWereHarmed[=/=]TakeThat: He's an unflattering caricature of UsefulNotes/MuammarGaddafi.
* MonumentalTheft: Once hired Octane and Trypticon to steal landmarks like Fort Knox and the Eiffel Tower.
* PresidentForLife: One of his proclaimed titles is that he's President for life.
* TryToFitThatOnABusinessCard: He has quite a lot of titles that he feels the need to mention every time he says his name.

!! G.B. Blackrock
The CEO of Blackrock Industries.
* AmbiguouslyJewish: His last name sounds like an Anglicization of Schwarzstein, and creator Bob Budiansky said he based the character's name off that of his friend Gary Bennett Schwartz; both Budiansky and Schwartz are Jewish.
* TheCasanova: Sometimes tries to pick up girls.
* {{Expy}}: Of [[Comicbook/IronMan Tony Stark]].
* HonestCorporateExecutive: He's an honest businessman allied with the Autobots.
* ScrewTheMoneyIHaveRules: He will not condone illegal practices.

!! Nova Prime
A Matrix-bearer and leader of the Cybertronian people from countless millions of years before the time of Optimus Prime, Nova Prime ruled in a time when the Cybertronian race was enjoying a golden age of prosperity and power. Seeing his species as the greatest form of life in the universe and thus deserving of its rulership, the expansionist Nova gathered a crew of loyal and likeminded Transformers to crew a vast spaceship known as the ''Ark-1''; ostensibly theirs was a mission of exploration and mapping the galaxy, but in reality their goal was one of conquest. Fortunately for most other forms of life, the ''Ark-1'' and its crew vanished into the [[NegativeSpaceWedgie Benzuli Expanse]] shortly into its maiden voyage and was presumed destroyed with all hands. This turned out not to be the case, however; instead of destroying them, the Benzuli Expanse flung Nova Prime and his crew into the [[{{Mordor}} Dead]] [[EldritchLocation Universe]], its fell energies transforming them until they were neither living nor dead. Now, millions of years later, '''Nemesis Prime''', still holding to his expansionist ideals, intends to merge the Dead Universe with our own in order to create a reality where Cybertronian life reigns supreme, but how much of this is his own plan and how much of it comes from the creeping, malevolent sentience which sustains him cannot be determined...
* AdaptationalHeroism: The original Nova Prime was always a villain, even back when he was a "good guy" he was deeply racist and heavily promoted the ideal humanoid Cybertronian at the expense of both non-humanoid Cybertronian life and all other Organic life. He had intended to create an empire that expanded across space, before he was turned into Nemesis Prime which made him an OmnicidalManiac. Every time he appears in other continuities he's recast as a better person.
** The ''Transformers Legends'' game has Nova Prime as a peaceful ruler of Cybertron who must confront Nemesis Prime, his evil future self.
** ''ComicBook/TransformersShatteredGlass'' recasts Nova as the new identity of the revived Evil Optimus Prime, who is now a good-guy.
** In ''VideoGame/TransformersDevastation'', Nova was an idealistic and moral leader of Cybertron who was corrupted by Unicron.
* BackFromTheDead: [[spoiler: Briefly returns thanks to the D-Void, but is ultimately killed by Galvatron again, and in ''ComicBook/TheTransformersDarkCybertron'' he returns to life once again now calling himself Nova Prime again]].
* BigBad: For the IDW comics prior to ''ComicBook/TheTransformersAllHailMegatron''.
* CastingAShadow: He has shadowy energy surrounding him.
* DarkIsEvil: He has a sinister appearance and isn't a good guy at all.
* EvilCostumeSwitch: A variation; when we first see Nova prime in a flashback his colour scheme [[LightIsNotGood is predominantly white]], but as Nemesis Prime [[PaintItBlack his colour scheme is inverted.]]
* TheEvilsOfFreeWill: Sought to eliminate free will from Cybertronians and the galaxy at large.
* TheUndead: Because of exposure to the energies of the Dead Universe, he's neither living nor dead.

!! Quintessons
->'''Voiced by''': Various; Regis Cordic, Roger C. Carmel, and Jack Angel were the primary voices.

-->'''Prosecutor''': Guilty or innocent?\\
'''Magistrate''': Innocent.\\
'''Prosecutor''': Feed him to the Sharkticons.

A hostile race of mechanical, squid-like beings with up to five faces on their bodies.
* AbusivePrecursors: In those continuities where the Quintessons colonized Cybertron in the distant past and built robotic slaves who would eventually turn against their masters and become Autobots and Decepticons. Needless to say, the Quintessons aren't happy about being given the boot by their former servants, and seek to either re-enslave or destroy all Cybertronians.
* AlwaysChaoticEvil: There are almost no good Quintessons. Al-Badur helped the Cybertronians, but he turned on them in the end. Pentius initially presented himself as a neutral malevolent force meant to steer Megatron towards evil. He was wicked, but firmly believed in bettering Megatron to the point where he approves of Megatron killing him for survival, and even Pentius reduced to a spark, betrays Megatron for his own gain. The only two Quintessons who are known to be definitely good are Aquarius, who comes from a MirrorUniverse, and Klementia, who resurrected Optimus Prime in ''The Return Of Optimus Prime'' and, according to supplementary materials, would later go onto forge a peace between the Quintessons and the Autobots and spearhead a number of reforms in Quintesson society.
* CardCarryingVillain: "[We] are ''Quintessons''! ''Arrogance'' is our life’s blood, ''ambition'' is our food and drink, but most of all, ''hubris is the air we breathe''!!
* CombatTentacles: They have tentacles that they often use to defend themselves.
* DirtyCoward: They'll betray anyone to save their own skin.
* FantasticRacism: Have disdain for all other races, Cybertronians and humans in particular.
-->"Humans are disgusting creatures, but worthy of study, if only to find a better way of destroying them."
* HangingJudge: The trials they hold for their prisoners always end with the prisoner being executed.
* {{Jerkass}}: They enjoy tormenting and killing people for no good reason.
* KangarooCourt: Tend to capture beings and subject them to mock trials that serve no purpose except their own amusement. They are fond of simply declaring everybody who they try as "innocent", then dropping them into pits full of Sharkticons anyway. They admit pleading for one's life "sometimes helps... but not often."
* MadScientist: Many of them enjoy performing experiments on their captives.
* MechaMooks: In the Marvel G1 comics, they are Unicron's enforcers that hunt down and pick off anything that escapes his maw.
** In the 3H comic continuity, Unicron hired them to seek out the body of Primus. After discovering him in the form of Cybertron, the Quintessons decided to tell Unicron about it later. And the rest is history.
* SharkPool: Pools of Sharkticons are among their main weapons.
* SquishyWizard: Get past their technological defenses and they are easy prey. They have no aptitude for direct combat and can easily be overpowered by humans despite their immense size.
* {{Toyless Toyline Character}}s: To date, no Quintesson toys have been released, probably because they would be way too complex even for today. In 1986, they would be ''impossible'' to make due to the limitations of toy technologies.
* WarForFunAndProfit: Quintessons were war profiteers in the original cartoon.

A ravenously hungry horde of transforming robots who turn into sharks, the Sharkticons serve as the Quintessonian muscle and their main method of execution. They're also not very bright, and could easily be turned against their masters if given half a chance.

* DumbMuscle: Sharkticons are not very bright.
* EliteMooks: The Allicons are their smarter, bigger, nastier cousins, who turn into alligators. They're usually higher up the food chain than the Sharkticons.
* EpicFlail: Sharkticons can detail their tails to use as flails. So far, none have been shown doing this in fiction.
* FatBastard: Both shark and robot modes look pretty chubby. But then, they do eat a lot.
* MixAndMatchCritter: Despite the name, Sharkticons look like a mix of sharks and piranhas.
* SlaveRace: For the Quintessons.
* ZergRush: Sharkticons aren't very smart, not very strong and not very durable. Their advantage lies in swarming enemies and devouring them.

!! Primus
The Lord of Light and counterpart of Unicron, Primus is the Creator God of the Transformers. The spark of each Transformer is a piece of his lifeforce, and combined, they form his essence, the Allspark. He created the Thirteen original Transformers to man his body in planet mode, but when The Fallen betrayed him, Primus was forced to go into stasis, in an effort to prevent Unicron from finding Cybertron and devouring it, which would destroy that universe. Like his brother and his creations, Primus is a multiversal singularity, meaning there is only one version of Primus in the vast multiverse.
* BigGood: The highest authority there is on the Autobots' side, surpassing even Optimus Prime.
* CosmicKeystone: If Primus dies, reality tends to get a little... ah, ''weird''. The bizarre nature of the Japanese G1 continuity has been put down to his near-destruction during ''Headmasters''.
* FailedASpotCheck: He claims to be able to track Unicron's presence. Somehow, he failed to notice Unicron until he was quite literally right on top of him (something Kup even points out. How the hell do you miss a guy the size of a planet?)
* FightingAShadow
* GeniusLoci: He ''is'' Cybertron, or, at least, trapped within Cybertron. It varies DependingOnTheWriter.
* GuileHero: The original version of his and Unicron's origin had Primus tricking both of them into asteroids.
* HorribleJudgeOfCharacter: His G1 comic incarnation took ''Galvatron'' at his word.
* KingInTheMountain: In most continuities, he's sleeping to hide himself from Unicron, and will only wake up when "all are one". As can be guessed, he doesn't wake up very often.
* LightIsNotGood: He created the entire Cybertronian race to serve as little more than cannon-fodder. During the G1 comic, he loudly appointed Optimus leader of the combined Autobot-Decepticon forces knowing Unicron's sleeper-agents would target him directly.
* ManipulativeBastard: And he's supposed to be the "good" one.
* MinorMajorCharacter: Even though he created the Cybertronian race, he's seldom given any prominence.
* MultipleChoicePast: He's either a primordial force or the former lab assistant of the MadScientist Primacron.
** In the DK ''Ultimate Guide'', he actually split from Unicron. ''Really.''
* OmniscientMoralityLicense: Everything he does is in some way to combat Unicron and protect the universe, but that doesn't mean its convenient or pleasant for the little guys.
* PhysicalGod: He's the creator god of the Transformers.
* WorldOfBadass: He is Cybertron. And nobody would deny the Transformers are Badass.

!! Unicron
->'''Voiced by''': Creator/OrsonWelles (''WesternAnimation/TheTransformersTheMovie''), Roger C. Carmel (''WesternAnimation/TheTransformers'')

The primordial personification of Chaos and Darkness, Unicron is the ultimate force of evil in Transformers--not simply in Generation 1, but in ''all'' iterations of the brand. Like his brother and archenemy Primus, Unicron is a multiversal singularity--in all the myriad realities of the transformers universe, there is only one Unicron.[[note]]This may not apply to the Franchise/TransformersAlignedUniverse.[[/note]] The Chaosbringer has seen our existence, our reality, and he has taken offense; Unicron's greatest desire is to consume and annihilate all of creation, all possible realms of existence, until naught remains but an infinite void of absolute nothingness, at the center of which he shall sleep forever more, his tasks complete. You cannot destroy Unicron permanently; blow up his physical body, and he simply reforms in another part of the multiverse to continue his never-ending quest to devour all reality.
* AchillesHeel: The energy of the Matrix of Leadership can devastate his physical form.
* AlwaysABiggerFish:
** The reason why Primus doesn't just fight Unicron directly. Every time they've fought, Unicron's handed him his ass.
** While they haven't come into direct conflict (yet), Unicron has been trumped as the biggest threat in the franchise, by the [[EldritchAbomination Elder]] [[HyperspaceIsAScaryPlace Gods]].
* AlwaysSomeoneBetter: According to the first versions of their origin, atleast, Unicron managed to turn his asteroid prison into a planet first. Primus stole the idea of transforming from him.
* TheAntiGod: Compared to Primus.
* AsLongAsThereIsEvil: He gloats that he'll never be gone for good as long as evil beings exist.
* DealWithTheDevil: Occasionally the Chaosbringer will see fit to empower mortal creatures with a fragment of his essence, upgrading their bodies and granting them new abilities in order to carry out whatever tasks he requires of them. The most well-known of these Heralds of Unicron is [[WesternAnimation/TransformersTheMovie Galvatron]], though there have been many others, and not all of them exhibit the same degree of independence and free will as Galvatron did. Unicron cares little for his pawns, however, and in the end his goals call for their consumption as well.
** WithGreatPowerComesGreatInsanity: Service to Unicron leads to madness and loss of self.
* EldritchAbomination: Those who have seen only the movie believe Unicron to be little more than a PlanetEater, but the truth of the matter is that Unicron consumes ''all things''--matter, existence, time and space, ''all of these'' are mere morsels snapped up to sate his unholy hunger, however briefly.
* EvilCannotComprehendGood: Going by what he says after Optimus forces the Matrix down his throat in the comics, Unicron actually doesn't understand concepts of good or love or life.
* EvilIsPetty: A truly inane one. He finds it an insult to his very being that any other living creature has the right to exist other than himself, and thus sets upon correcting that and destroying it all.
* EyeBeams: He can fight lasers from his eyes.
* FightingAShadow: In some incarnations, he isn't always fought directly and instead sends an illusion to fight on his behalf.
* GeniusLoci: His alt mode is a giant planet.
* GodOfEvil: He's a godlike being and is basically the Satan of the Transformers franchise.
* GreaterScopeVillain: He is a bigger threat than Megatron, but he isn't encountered until ''WesternAnimation/TheTransformersTheMovie'' and seldom returns after his defeat.
* ItsAllAboutMe: To the point where he is offended that anything other than him can even exist.
* KnightOfCerebus: Unicron outshines every other Knight in Transformers. If he shows up, the situation is officially beyond bad.
* LaserGuidedKarma: After his defeat, his head blown off and was sucked into Cybertron's orbit, leaving the former living planet little more than a moon for one of the worlds he tried to devour.
* LosingYourHead: Rodimus Prime reduced him to a head, but he is still incredibly dangerous whenever he regains consciousness.
* MadeOfEvil: His internals are either Dark Energon or Angolmois, depending on the continuity. Neither of them are recommended by the surgeon general (Angolmois in particular can mutate the body). Curiously, in some continuities both substances have been able to create life.
* MindRape: Throughout TheMovie, Unicron often used some sort of sensory overload to Galvatron's mind whenever the latter considered betraying or disobeying him. He seemed to lose that ability after his defeat, thus could not recall Galvatron and had dangerously minimal control over [[TheStarscream his successor]].
* MultipleChoicePast: He's either a primordial entity like Primus or the creation of a MadScientist named Primacron who rebelled against his creator and decided to destroy everything.
* OmnicidalManiac: The Dark God utterly loathes existence with a passion, and is slowly making good on his goal of consuming all of creation; Unicron has already devoured more than a fifth of all possible universes.
* OOCIsSeriousBusiness: In one instance, as he was getting close to Cybertron, Unicron was so determined to kill Primus he completely passed by a perfectly good planet.
* PhysicalGod: Specifically, a dark god.
* PlanetEater: When Unicron says he wants to be alone, ''he damn well does something about it''. If he eats everything, then all will be a part of him, and he will finally be alone.
* ReadingsAreOffTheScale: Usually, stats are 1 to 10 for a Transformer. Unicron's stats whenever a toy of his full body is released has many of his stats listed as unknown. One online retailer exclusive figure has them set at '''''Infinity'''''
* TheRedBaron: The Dark God, the Chaos-Bringer.
* SpacetimeEater: He won't be satisfied until he's devoured ''all'' of reality.
* SuperPersistentPredator: Doesn't matter where Primus goes or where he hides himself. Unicron will hunt him down for as long as it takes.
* UnwittingPawn: To Starscream in "Ghost in the Machine". And he ''[[DidYouJustFlipOffCthulhu actually succeeds]]''.

!! The Fallen
->'''Voiced by''': Tony Todd

One of the Thirteen Original Transformers created at the dawn of time by Primus to crew his planetary shell, the being once known as '''Megatronus Prime''' served as the guardian of entropy, overseeing the orderly dissolution of all things in preparation for the next creation. Destruction came to fascinate him too much, however, and as he forgot his original purpose he gave himself to Unicron, turning on his former master and his brethren amongst the Thirteen. '''The Fallen,''' as he is now known, is a cosmic force of evil, his physical form little more than a cage for the raging inferno of chaotic power which constitutes his essence; he can only be defeated, never destroyed. Like Primus, Unicron, and the other members of the Thirteen, The Fallen is a multiversal singularity--as such, The Fallen of Dreamwave Comics and The Fallen [[Film/TransformersRevengeOfTheFallen from the Michael Bay movies]] are the same character.
* BareHandedBladeBlock: He manages to catch Grimlock's energon sword one handed. Even more impressive given the properties of energon swords on Cybertronians mean it's like a lightsaber for them. And it doesn't even ''annoy'' the guy.
* DealWithTheDevil: Like his dread master, The Fallen has been known to bargain with and empower the lesser mortals of the multiverse, tempting them with the forbidden promises of dark science and entropic magic that they might see to his dark designs. He himself made a deal with Unicron.
* EnergyBeing: The body we see is merely a shell for the chaotic energies that now comprise the Fallen's form.
* TheDragon: To Unicron.
* FallenAngel: He was one of the original 13 Transformers, but then became an acolyte of Unicron.
* FightingAShadow: He often sends an emissary to fight on his behalf.
* TheNameless: Loses his name after siding with Unicron. The Fallen is more of a descriptor than a name.
* NighInvulnerable: Primus made him to fight Unicron directly, and it shows. Throughout ''The Dark Ages'', pretty much nothing the Autobots try on him does anything. It takes divine intervention to get rid of him.
* OmnicidalManiac: He wants to kill everyone.
* PhysicalGod: He is extremely powerful and formidable.
* {{Retgone}}: One of the powers he grants in ''Power of the Primes'' is the ability to erase people from existence.
* SatanicArchetype: A FallenAngel who is one of the best of his kind, but becomes the field leader of evil.
* SealedEvilInACan: After his deal with Unicron, he got thrown into subspace. The Decepticons and their early tinkering with Space Bridges let him loose.
* TankGoodness: His alt-mode is a tank, though he's never shown using it in his appearances.
* WreathedInFlames: The eldritch energies contained within The Fallen's body cause him to appear constantly ablaze in unholy fire. Sadly, every depiction of him since his first appearance has done without this.

!!The Thirteen

The first thirteen Cybertronians created by Primus, intended to fight Unicron directly. Their numbers include Prima, Vector Prime, Alpha Trion, Solus Prime, Micronus Prime, Onyx Prime, Amalgamous Prime, Alchemist Prime, Nexus Prime, Quintus Prime, the Liege Maximo, the Fallen and an unidentified thirteenth member.

For Alpha Trion's info, see the Autobot's page.

* AdaptationalVillainy: Onyx and Nexus were on the receiving end in IDW's comics. They're joined by Alchemist in ''Power of the Primes'', who is made a Decepticon.
* CanonImmigrant: Of them, Prima, Alpha Trion, the Liege and the Fallen all started off in G1 based continuities (also possibly Nexus, though his continuity of origin is... difficult to pin down). Vector Prime first appeared in ''Cybertron'', and the rest come from the Aligned continuity.
* TheCorrupter: Alchemist can "awaken a shadow spark" in 'bots.
* GadgeteerGenius: All of Solus Prime's abilities in ''Power of the Primes'' revolve around giving people the ability to create things.
* KillEmAll: Their first real mention, in the Dreamwave continuity based ''The Ultimate Guide'', said that they'd all died in the fight with Unicron (except the Fallen). Pretty much every depiction since has gone with something different.
* TheParagon: Going by his ''Power of the Primes'' profile, Prima is bold, brave, fearless and selfless.
* {{Precursor}}: They are the precursors to all Cybertronians.
* TheSmurfettePrinciple: Solus is the only gal in the group.

!! Tornedron
->'''Voiced by''': Neil Ross

Another being created by the MadScientist Primacron, technically making him Unicron's little brother. A being of pure energy that exists to consume the energy of the universe. Was eventually destroyed by Grimlock applying ReversePolarity to make him dissipate.
* EldritchAbomination: He is a large fearsome entity that feeds on the life energy of others.
* EnergyAbsorption: He thrives by feeding off other creatures' life energy.
* EnergyBeing: His default form is a being of energy.
* FeedItWithFire: Attacking him just makes him stronger, since he absorbs energy.
* OmnicidalManiac: Like Unicron before him, his goal is to wipe out all life.
* OneToMillionToOne: Does this to pursue multiple targets.
* VoluntaryShapeshifting: Assumes the forms of many predatory beasts.
