Note this page may contain details and tropes on characters who appear throughout the rest of the Anime/UnicronTrilogy as well.

'''Spoilers are uncovered at your own risk.'''



[[folder:Optimus Prime]]
!!Optimus Prime

->'''Voiced by:''' Creator/ToruOkawa (JP) (Armada), Creator/KatsuyukiKonishi (JP) (Energon), Creator/TaitenKusunoki (JP) (Cybertron); Creator/GaryChalk (EN) (All series)

The Autobot commander of the forces on Earth, Prime leads the team through the Mini-Con Battles, against Unicron (twice) and finally in an effort to save Cybertron and reality from the Unicron Singularity.
* AFatherToHisMen: Goes absolutely berserk after [[spoiler:Smokescreen's]] near death. It's seen quite often throughout the show, which makes him a particular contrast to Megatron throughout the trilogy.
* AntiHero: While he's still, without question, [[TheHero a hero]], it's worth noting that this Prime seems more willing to resort to violence compared to others. This is exploited by [[spoiler: Sideways/Unicron]] who accuses Optimus of being as much of a BloodKnight as Galvatron, despite Optimus claiming he fights merely because he ''has'' to. [[spoiler: Unicron]] is proven somewhat right in the ''Armada'' finale when Optimus and Galvatron have their final brawl in that series.
* AuthorityEqualsAsskicking
** BigBadassRig: A futuristic semitruck in ''Armada'', a car transporter in ''Energon'', and a fire truck in ''Cybertron''. In the last series, ''it even lets him fly''.
** TookALevelInBadass: In ''Armada'', he was still a tough guy, but struggled a lot more in combat. By ''Cybertron'', [[spoiler:he is strong enough to kill Galvatron in a SingleStrokeBattle.]]
* BenevolentBoss
* BewareTheNiceOnes
* [[spoiler:DeathIsCheap]]: In ''Armada''. He's back three episodes later.
* TheGoodCaptain: As is tradition.
* TheHero: As is tradition.
* LookWhatICanDoNow: In ''Armada'', he powerlinks with Jetfire, and later the pair link with Overload. Normally this equates into instant win. In ''Energon'', he powerlinks with more or less the entire Autobot army, forming Optimus Supreme to fight [[spoiler:a revived and very, very pissed off Unicron.]]
** In ''Cybertron'', he combines with Leobraker to form "Savage Claw" mode and Wing Saber to form "Wing Optimus".
* NiceGuy
* PapaWolf: Act like this towards the Mini-Cons.

[[folder:Hot Shot]]
!!Hot Shot

->'''Voiced by:''' Creator/BrentMiller, then by Creator/KirbyMorrow for ''Cybertron''

Resident team rookie, Hot Shot has learned a lot of hard lessons throughout his career, much to the chagrin of some of the older bots.
* CompositeCharacter: Of [[WesternAnimation/TheTransformers Bumblebee]], [[WesternAnimation/TransformersTheMovie Hot Rod]], and [[WesternAnimation/BeastWars Cheetor]].
* CrouchingMoronHiddenBadass: Despite his status as rookie, he is still very capable of kicking butt. He even gets to wield the Star Saber for a while in ''Armada''.
** TookALevelInBadass: After his "Cybertron Defence" upgrade.
* BigBrotherMentor: To Sideswipe, who actually starts referring to him as his brother. Possibly to the kids too.
* CoolCar: He normally becomes a blue-and-yellow sports car, but in the second half of ''Cybertron'', he is revived and upgraded so that he becomes a blue Humvee-like vehicle instead.
* FriendToAllChildren
* HonorBeforeReason: At least once, he rushed in to save two Velocitron natives in danger, shortly after Optimus had given him the order to not interact with said natives.
* KidAppealCharacter: He almost always sports yellow in his colour scheme, and interacts with young humans the most.
** But in ''Cybertron'', he's blue with yellow highlights. And in ''Energon'' the role is partially shifted to Ironhide, who disappears not too long after.
* TheLancer
* LightningBruiser: Though not ''quite'' as fast as Blurr.
* PrideBeforeAFall: ...and totally let the power that the Star Saber granted him go to his head. It ends painfully.
* RebelliousSpirit
* ShouldersOfDoom: [[ That "wHy mY sHoUlDeRs huRt" meme?]] Guess where it came from.
* SuperSpeed: By the time of ''Cybertron''.
* TookALevelInDumbass: In ''Energon'', he's depicted as a mature veteran. In ''Cybertron'', he's back to being the immature rookie as he was in ''Armada''.
* YoungGun: Probably not helped by the fact that his first foray into human culture consisted of {{spaghetti western}}s.

[[folder:Red Alert]]
!!Red Alert
->'''Voiced by:''' Creator/BrianDobson, Creator/DaranNorris (video game) (EN), Creator/IkuyaSawaki (JP)

CombatMedic of the Autobots, he may seem the NonActionGuy, but harm his bots and you will regret it.
* BrainsAndBrawn: Red Alert's the brains, Hot Shot's the brawn.
* BadassBookworm
** AdaptationalBadass: By the time of ''Cybertron'', compared to both his G1 and Armada counterparts, this version of Red Alert is a real ''beast'' in a fight.
** TookALevelInBadass: In ''Cybertron'', his MidSeasonUpgrade is this in spades.
* CombatMedic: Though he spent most of his time on the battlefield fighting, more than anything else.
* {{Expy}}: Of his G1 counterpart and Ratchet.
* GeniusBruiser
* HeadbuttingHeroes: With Hot Shot while on Velocitron, Though the pair eventually come to an understanding.
* MinoredInAsskicking: He usually stays back at base in ''Armada'', but he makes a pretty good showing in ''Cybertron''.
* MissionControl
* ShoutOut: His Armada incarnation particularly shares a few cues with Franchise/{{Robocop}}.
* TheSmartGuy
* TheSpock: Not entirely, but he is pretty reserved.
* SwissArmyAppendage: Lost his hand in battle, got a cool new... thing.


Smokescreen originally intended to be one of the team members who accompanied Optimus Prime to Earth, but he entered the spacebridge portal late, and as a result, he materialized some time later then they did.
* BigFun
* BoisterousBruiser
* CommutingOnABus: in the Dreamwave comics, he'd go long stretches without appearances.
* {{Demonization}}: The kids all assumed [[spoiler:that he was a Decepticon when he first appeared. Of course the fact that he chased them all over the place and didn't introduce himself properly probably didn't help much.]]
* IntergenerationalFriendship: Out of all the team, he and Hot Shot seem to be particularly good friends.
* NiceGuy
* StoutStrength
* ThoseTwoGuys: With Scavenger, in the comics.


Scavenger is an old war veteran. [[spoiler:Who just so happens to be the Autobot who taught Optimus Prime everything he knows]].
* TheBigGuy
* CapedMecha
** BadassCape: Transformers as a whole don't need capes. His is purely for RuleOfCool.
* ChuckCunninghamSyndrome: Disappears after ''Armada''.
* GeniusBruiser
* OldMaster: [[spoiler: He taught Optimus Prime after all.]]
* OldSoldier
* ReverseMole: [[spoiler:Though given the folder he's been placed under, you probably guessed this already]].
* SeniorSleepCycle: in the middle of a training session. [[spoiler: Hot Shot is not impressed]].
* StealthMentor
* WalkingSpoiler: It turns out that he's actually an Autobot in disguise.

->'''Voiced by:''' Creator/BrianDrummond (EN), Creator/IsshinChiba (JP)

Cool and aloof, Blurr is one of the later additions to the Autobot ranks. He initially thought of the Mini-Cons as mere tools, a thought which Hot Shot slowly shot down.
* ColdSniper
* DefrostingIceKing: Towards Hot Shot.
* FantasticRacism: Thinks of the Mini-Cons as ''just weapons'' for a long while.
* GrumpyBear
* IneffectualLoner: In his introduction.
* ChuckCunninghamSyndrome: Disappears after ''Armada'' and never reappears again (unless you think the toyline character from ''[[Anime/TransformersCybertron Cybertron]]'' is him).

->'''Voiced by:''' Creator/ScottMcneil, then Creator/BrianDrummond

The second-in-command of the Autobots on Cybertron, Jetfire departed Cybertron and arrived on Earth in order to help Optimus and the others.
* AfraidOfNeedles
* ArchEnemy: Starscream was his rival in Armada and Energon. Thundercracker is his in ''Cybertron''.
* ArrogantKungFuGuy: Like this for a long while in ''Armada''.
* UsefulNotes/AustralianAccent
* BoisterousBruiser: Very ''very'' boisterous.
* CoolStarship: He becomes a space shuttle in both ''Armada'' and ''Energon''.
** CoolPlane: In ''Cybertron'', he becomes a cargo jet with a space shuttle front half.
* DeadpanSnarker: Definitely in ''Cybertron''.
* TheLancer: While the Bots don't form a FiveManBand per se, he has shades of this trope.
* LargeHam: In ''Armada'', not so much in ''Engeron'' or ''Cybertron''.
* NumberTwo: It does seem a little odd that Optimus would pick a hot-head like him to be second in command. That is, until you see them ''together'' in battle.
** In the comics, however, he's much more calm and reserved.
* OneManArmy
* TallDarkAndSnarky: Again, in ''Cybertron''.

->'''Voiced by:''' Creator/SamuelVincent

Hot Shot's newest partner, it didn't take long for Sideswipe to be captured by Hot Shot's friend-turned-foe, Wheeljack. Sideswipe was saved but the experience taught him a harsh lesson about war, leading him to quickly sober up.
* {{Adorkable}}
* CuteBruiser: Though not much of a bruiser, he has his moments.
* ChildSoldier
* GeniusDitz: He's good at cracking codes, but not much else.
* NewMeat: And it's ''very'' obvious to everyone.
* TagalongKid


->'''Voiced by:''' Creator/KiyoyukiYanada (JP) (Armada), Junichi Endo (JP) (Energon), Creator/JojiNakata (JP) (Cybertron); Creator/DavidKaye (EN) (All series)

Leader of the Decepticons. Megatron is a malicious, powerful leader. A refined, focused general who treats his men with little care, yet still infuses them with genuine respect for him and the Decepticon cause.
* AffablyEvil: ''Armada''. When it comes to the next two series, however...
** FauxAffablyEvil
* AntagonistInMourning: [[spoiler:Optimus being dead]] wasn't nearly as fun as he thought it would be.
* BadassBoast: From the comic - "You are in my way, and anything in my way, '''I GO THROUGH!''' My troops may have fallen, but I AM MEGATRON!"
* BadBoss: Became more and more his shtick with each incarnation. In ''Armada'' dents in his reign and planning started occurring as a result of his abusive and control obsessed treatment of his Decepticon army. By ''Energon'' he is a pretty straight up violent sociopath who will attack, reformat or kill those who remotely defy him, while in ''Cybertron'' he is a callous manipulator who sees all those that serve under him as dispensable pawns, leading his ''entire army'' to turn their back on him.
* BigBad: [[spoiler:Until Unicron shows up]]. Played straight in ''Cybertron'', as [[spoiler:Unicron has long since disappeared]].
* BladeBelowTheShoulder: Only seen near the end of the ''Armada'' series, but it does ''massive'' damage when it finally shows up.
* CardCarryingVillain: Tends to display snarky awareness to being an inflicter of evil, especially in the dub.
* TheComicallySerious: His deadpan snark in spite of his vicious disposition leans him into this, especially in ''Cybertron''.
* ControlFreak: He chastises, threatens or outright brutally beats down his men for not following his orders to a tee. Verges on AGodAmI in his ambitions in ''Energon'' and ''Cybertron''.
* CoolCar: One of his two alt-modes (he is a triple changer) in ''Cybertron''
* CoolPlane: His main alt-mode in ''Energon'', and one of his two alt-modes (again, he is a triple changer) in ''Cybertron''.
* CreateYourOwnVillain: Reversed. Arguably the Megatron incarnation most apt at making enemies out of his own Decepticon soldiers [[MistreatmentInducedBetrayal due to his abusive, power hungry ways]]. Taken UpToEleven in ''Cybertron'' where ''all'' of his minions eventually HeelFaceTurn after [[YouHaveOutlivedYourUsefulness he renders their lives meaningless]].
* DefiantToTheEnd: In all three series, he ultimately chooses death over submitting or accepting control to Unicron or another power. He may be a brutal, dastardly tyrant, but at least he's damn well consistent about it.
* DidYouJustPunchOutCthulhu:
** [[spoiler:It was his death that stopped Unicron, in ''Armada'' and ''Energon'']].
** In the comic [[spoiler:he defeated G1 Galvatron in one-on-one combat, albeit with help from the Star Saber]].
* EvilLaugh
* AFatherToHisMen: Starts to slip towards this in Armada, particularly after his men start taking issues with his needless hostilities and prove themselves ''very'' capable of fighting back if pushed too far. Unfortunately this doesn't stick after he is reincarnated.
* HairTriggerTemper: By far one of the most volatile incarnations of Megatron, with his own minions often the brunt of his violent tantrums. He cooled down to befit his more manipulative tactics in ''Cybertron'', but even then he's hardly ''not'' this trope, especially when he's losing.
* HeroicSacrifice: At the end of Armada he chooses to fall to his death so that he can end the war a deprive Unicron of the power he needs to revive.
* KilledOffForReal: [[spoiler:In the 2nd to last episode of ''Cybertron'', he dies again, but unlike the previous shows he never comes back.]]
* MoreDakka: In ''Armada'', he could activate his "Full Blast" mode, effectively turning him into a walking minigun.
* NobleDemon: During ''Armada'' only. Afterwards, it got [[OmnicidalManiac much]] [[KickTheDog worse]], and with more or less no explanation why.
* OneManArmy: The comic version manages to lay waste to four armies worth of Terrorcons in a matter of minutes.
* TheOnlyOneAllowedToDefeatYou: Optimus Prime is his to destroy. Sixshot in particular suffered very brutal dismissal for trying to dispose of Optimus himself throughout ''Energon'', a disposition that [[DefiantToTheEnd did not remotely waver]] when [[TheStarscream Sixshot half slagged Galvatron to do so]].
-->'''Sixshot:''' ''*charges and aims laser at Galvatron*'' Optimus Prime will be ''mine''!
-->'''Galvatron:''' ''NEVER!!!''
* PragmaticVillainy: In ''Cybertron''. Despite still having a nasty attitude, he is smart enough to keep most of his Decepticons motivated and capable, only truly disposing of those that betray him. Many of his minions even get upgrades at his choosing. He best exemplifies this through a HannibalLecture to Optimus later in the series, having kept his minions loyal to him until he finally achieved his goals and didn't need them anymore.
* RoaringRampageOfRevenge: In the ''Energon'' comics. Ten years of pent up anger get spent in the space of a few minutes.
* TankGoodness: His alt-mode in ''Armada''.
* TeamDad: A horrible abusive dad, but a dad nonetheless. This changes after ''Armada''.
* TookALevelInJerkass: In ''Energon'', his NobleDemon and AffablyEvil traits mysteriously vanish with no explanation, and he becomes even more ruthless and crueler then he already was. He gets even worse in ''Cybertron''.
* VillainTeleportation: In Dreamwave's ''Energon'' comics, he rebuilt himself with a fancy teleportation ability that can take him across interstellar distances in seconds. It does come with the drawback of soaking up a lot of energy, though.
* WorthyOpponent: To Optimus Prime in ''Armada''. [[spoiler:To the point that he falls into a depression when he actually defeats him and hands control of the Decepticons over to him at the end of the series.]]

-> '''Voiced by:''' Creator/JinYamanoi (JP) (Armada), Creator/NobuoTobita (JP) (Energon), Creator/TakayaKuroda (JP) (Cybertron); Creator/MichaelDobson (EN) (All series)

Megatron's poorly-treated second in command. He loathed Megatron, because of the sheer mistreatment and contempt Megatron often piled onto him, Megatron always seemed to expect to much from him.
* AdaptationalBadass: No Starscream since him has come close to doing what he's done in ''Cybertron''. Fights Primus twice and lives? Check, though he still loses both times. [[spoiler:Only non-comic relief Decepticon left alive at the end of ''Cybertron''?]] Check. Fought off eleven Autobots to steal the Omega Lock? Check. While his living up to the [[TheStarscream trope he named]] has been done by [[WesternAnimation/TransformersAnimated other]] [[WesternAnimation/TransformersPrime Starscreams]], he's done the best to date.
* AdaptationalHeroism: This version of Starscream is by far one of the kinder versions to hit the screen, as opposed to his ''Franchise/TransformersGeneration1'' and ''WesternAnimation/BeastWars'' incarnations, both of which were petty and treacherous. This changes for no apparent reason when he returns in ''Cybertron'', although it's implied that he CameBackWrong.
** The jarring change in personality makes more sense with the knowledge that in Japan, ''Galaxy Force/Cybertron'' has no connection to ''Micron Legend/Armada'' and ''Superlink/Energon''.
* AdaptationNameChange: In the original Japanese edit of ''Energon'', his character was in fact Nightscream, a separate Transformer who only had coincidental resemblance to Starscream. Only the dub establishes him as a true reincarnation to the character.
* AdaptationalVillainy: In the comics, he lacks any of his redeeming traits from the show.
* AntiVillain: [[spoiler:After he returns to the Decepticons, his loyalties are clearly conflicted.]]
* BackFromTheDead: [[spoiler:He dies at the end of ''Armada'' and ''Energon'', but returns not long after each time]].
* BigBadEnsemble: In ''Cybertron'', he eventually breaks away from Megatron and starts fighting both him ''and'' the Autobots.
* BreakoutCharacter: For ''Armada''.
* BreakTheHaughty: Though he wasn't as much of a jerk as most other examples.
* CameBackWrong: [[spoiler:His ''Cybertron'' incarnation is far less heroic and much more malicious than before]].
** In the ''Energon'' comic, he comes back as an energon ghost... and completely insane to boot.
* CompositeCharacter:
** His ''Armada'' characterization is essentially a mix of [[TheStarscream classic Starscream]] and ''Beast Wars'' [[DefectorFromDecadence Dinobot]].
** He also inherits the "conflicted loyalties" and "feels sympathy for humans" traits of ''Generation One'' Thundercracker, even getting a similarly blue-color scheme towards the end of the series. Said blue-color scheme was released ''as'' Thundercracker in the Hasbro ''Armada'' toyline.
* CoolPlane: Becomes a futuristic fighter jet in ''Armada'', [[{{Film/Transformers}} an F-22 Raptor]] in ''Energon'', and a [[Franchise/TransformersGeneration1 G1-inspired]] tetra-jet in ''Cybertron''.
* DarkChick: In ''Armada'' and ''Energon''.
* DefectorFromDecadence: [[spoiler:Though only temporarily, he tries to switch sides and join up with the Autobots in ''Armada''. It doesn't work out for a mix of reasons and he soon rejoins the 'Cons, but his loyalties are clearly conflicted afterwards]].
* {{Determinator}}: In all series of the Anime/UnicronTrilogy he has his moments. The ''Cybertron'' incarnation in particular is always trying to get ahead through schemes, and just never gives up. Even at his lowest point after his battle with Landmine, he pulls himself back up and displays such power equivalent to Galvatron's, the Autobots are defeated by his shock waves. His speech to Galvatron basically boils down to he's risked everything for power, and he's not going to yield.
* TheDragon: Throughout most of the trilogy.
* EvilSoundsRaspy: His voice in the English dub.
* {{Expy}}: Of Dinobot from ''WesternAnimation/BeastWars'', though he also shares some traits with the [[WesternAnimation/TheTransformers original Starscream]].
* HeelFaceRevolvingDoor: [[spoiler:He eventually defects to the Autobots in ''Armada'', then returns to the Decepticons after some problems force him to leave, then sacrifices himself to stop Galvatron ignoring the threat of Unicron. He spends some of his time worrying about his loyalties in ''Energon'', but this is given less focus until he sacrifices himself towards the end]].
* HeroicSacrifice: Twice. [[spoiler:The first happens when he keeps shooting at Unicron in an effort to convince Galvatron that both sides must ally.]] The second [[spoiler:occurs at the end of ''Energon'', when he follows his master into the giant sun.]]
* NobleDemon: In ''Armada'' and in ''Energon''. Not so much in ''Cybertron'', since he CameBackWrong.
* OneManArmy: In ''Cybertron'', mixed with VillainousValor.
* OnlySaneMan: In Armada, he's pretty much the only Decepticon who's both sane and competent.
* ProudWarriorRaceGuy: Mostly ''Armada'', but still retained traits of this throughout the rest of the trilogy.
* SmugSnake: In ''Cyberton'', though he starts far more shrewd and calculating than G1 Starscream, he's equally arrogant, and the fact he actually makes it part-way into his plans, capturing the Omega Lock and absorbing Primus' spark, only leads him to further think he is invincible, setting himself up for many defeats.
* TheStarscream: [[spoiler:Not until ''Cybertron'', and when he does, he jumps straight in.]]
* TokenGoodTeammate: In ''Armada'', he's the only Decepticon with a sense of honor. [[spoiler: He even pulls a HeelFaceTurn at one point and later gets a RedemptionEqualsDeath.]]
* WellDoneSonGuy: Strongly gives off this vibe towards Megatron's derogatory treatment of him in ''Armada''. The same thing gets on his nerves at the start of ''Cyberton'' too, though in this case he decides to just overthrow him.


Demolishor is extremely strong and acts very serious at all times. He is wholly devoted Megatron and the Decepticon cause, unquestionably following orders at every turn.
* BattleButler: To Megatron.
* CrouchingMoronHiddenBadass: Saves Megatron numerous times, but [[spoiler:the first time he does in ''Energon'', much [[TearJerker tragedy]] ensues]].
* CoDragons: Shared this post with Starscream in ''Armada'' until Thrust arrived. Returns to this position for a brief while in ''Energon'' until his rebuild.
* DumbIsGood: He's the closest thing to a "nice" Decepticon that you're going to find, aside from Starscream. Though interestingly, those two don't get along at all.
* ExpandedUniverse: He doesn't appear in ''Cybertron'', though a recolour of his original form was released as part of the toy-line.
* HandBlast: His fingers are gun barrels.
* HeroicSacrifice: In ''Energon'', [[spoiler:he saves Megatron's life at the cost of his old body being wrecked]]. He gets very poorly repaid for this.
* NoGoodDeedGoesUnpunished: In ''Energon'', [[spoiler:he saves Megatron's life and gets his old body wrecked. Rather than repair him and leave it there, Megatron transplants him into a body he doesn't want to be in and tampers with his memory]].
* PetTheDog: A quite memorable one in ''Armada''; following a defeat, Megatron decides to pass his nerves on Starscream by taking him to a room and delivering him a NoHoldsBarredBeatdown. Demolisher, realizing Megatron might well kill Starscream, ''breaks through the door'' to take his defense.
* TheRival: To Starscream, for the position of Megatron's right-hand man.
* TankGoodness: In ''Armada''. In ''Energon'', he becomes a dump truck instead.
* TookALevelInDumbass: After his body is destroyed in ''Energon'', he is rebuilt into a far dumber ape-like format with little of his memories of before, usually playing an incompetent comic relief role alongside Snowcat.
* UndyingLoyalty: Played mostly straight to Megatron, but the writers do subvert it at the end of ''Energon''. [[spoiler:When Galvatron hurls himself into the sun to stop Unicron and Starscream and Mirage follow]], he and [[spoiler:Snowcat]] don't bother to do the same.
* YesMan: Rarely questions Megatron, although his PetTheDog moment proves he's not totally obedient.


Cyclonus has a very "trigger-happy" personality, laughing and cackling as he fires his weapons almost completely at random on the battlefield.
* AxCrazy: Though it comes across as more annoying than genuinely frightening.
* BunnyEarsLawyer: Despite being cowardly and crazy, he's efficient when it comes to combat... usually.
* ButtMonkey: A lot of bad stuff happens to him. Sometimes he deserves it.
* DarkChick: For the Cons.
* EvilLaugh: Has a mad cackle until [[spoiler:Megatron changes him into Snowcat]] in ''Energon''.
* ForTheEvulz: Seems to have almost zero sense of camaraderie, and an even smaller grasp of right and wrong.
* TheHyena: Laughs like an absolute madman.
* LeeroyJenkins: There's no strategy for him, beyond wildly shooting at things.
* MinorInjuryOverreaction: He screams like a little girl every time he gets hit while in vehicle mode, which as you can imagine... happens a lot.
* StupidEvil: Cyclonus is not a smart guy.
* TriggerHappy: He loves to waste all of his ammo all at once.


Thrust is Megatron's top intelligence officer and master tactician.
* AdaptationalHeroism: In the comics, Thrust is not as cowardly or treacherous, [[spoiler:and by the time of ''Energon'' he's one of the few Cons still loyal to Megatron]].
* AintTooProudToBeg: [[spoiler:With Megatron, not that it did him any good.]]
* ButtMonkey: The Dreamwave version spends most of his screen time getting his ass kicked.
* CompositeCharacter: While he has characteristics of ''Generation One'' Thrust (a overconfident exterior that hides the DirtyCoward underneath, the cone-head design, etc.), he inherits several of ''G1'' [[TheStarscream Starscream's]] traits as well, being Megatron's outwardly sycophantic second-in-command who in actuality desires only personal power and who betrays Megatron to get it (''Armada'' Starscream was more of a NobleDemon, making this especially noticeable).
* DangerousDeserter: [[spoiler:Defects to serve Unicron]].
* DirtyCoward: [[spoiler:He talks a big game when he thinks Unicron will help him, but the moment he gets in trouble, he's begging Galvatron to save him.]]
* FamilyUnfriendlyDeath: [[spoiler:He gets crushed by Unicron. ''Squesh!'']]
* JerkAss: The other Cons often get sick of him for this reason.
* KarmicDeath: [[spoiler:He definitely got what was coming to him.]]
* KilledOffForReal: [[spoiler:Unlike other instances, Thrust does not come back]].
* KneelBeforeZod: [[spoiler:Tries to pull it on Galvatron, and gets crushed shortly after]].
* ProfessionalButtKisser: He's incredibly sycophantic when it suits him.
* RewardedAsATraitorDeserves: [[spoiler: Thrust dies by being crushed to death during Unicron's transformation, just after gloating to Megatron about his betrayal no less.]]
* SmugSnake: He's a decent strategist, but not good at improvising, which means his ego far overshadows his ability.
* SparedByTheAdaptation: [[spoiler:The ''Energon'' comic shows him as in charge of Cybertron's security systems and one of only two Cons to not immediately defect at the start.]] It probably helps that in that continuity, [[spoiler:he didn't defect to Unicron and is much more loyal.]]
* TheStarscream: [[spoiler: He betrays Megatron and allies himself with Unicron in an effort to consolidate more power]].
* StupidEvil: [[spoiler:He overestimates himself far too much when he defects.]]
* TheStrategist: He's actually pretty good at strategy, just not very good at improvising.
* UnwittingPawn: [[spoiler:Sideways manipulates him like a pro]].
* VillainousBreakdown: [[spoiler:As Unicron starts crushing him.]]
* VillainTeamUp: [[spoiler:He breaks away from the Cons to ally with Sideways and Unicron]].
* WouldHurtAChild: Don't forget that earlier on, [[spoiler:to escape the Cons and Autobots he threatened the kids.]]

[[folder:Tidal Wave]]
!!Tidal Wave

The lumbering giant Tidal Wave is the largest of the Decepticons, and proved himself a very powerful foe for the Autobots.
* TheBrute: For the Cons, being their go-to muscle.
* DumbMuscle: He's not very intelligent, but is by far one of the toughest.
* EliteMook: He's not just big, he's ''really'' tough to beat.
* EvilSoundsDeep: He's a giant Decepticon, what did you expect?
* GiantMook: Even after being sized down, he still towers over most of the other cons.
* HulkSpeak: Tidal Wave is one of the least eloquent characters in the franchise.
* SciFiWritersHaveNoSenseOfScale: In ''Energon'', his recoloured form is also much smaller, making him a little taller than Cyclonus. Yeah...
* UndyingLoyalty: To Megatron. Which may come across as oddly amusing, considering his VA voiced the treacherous (and much higher pitched) Terrorsaur.

->'''Voiced by:''' Creator/MichaelDaingerfield

Wheeljack, formerly an Autobot serving under Hot Shot. When Wheeljack was pinned beneath some debris during a fire, Hot Shot was forced to leave him to get help, but was prevented by his superiors from returning. Wheeljack believed that Hot Shot had abandoned him, and when Megatron found and rescued him, he swore loyalty to the Decepticon commander.
* AdaptationalVillainy: The previous incarnation of Wheeljack was a GadgeteerGenius firmly on the side of the Autobots. In ''Armada'', Wheeljack is a former Autobot turned Decepticon seeking revenge on a comrade that [[PoorCommunicationKills actually tried to help]]. [[spoiler:He does eventually reform, or at least forgives Hot Shot]].
* ArcVillain: Only in Past I and Past II.
* BestServedCold: He's not here for revenge. [[InconsistentDub Except he is]].
* DemotedToExtra: The Dreamwave comics utterly ignore his history, just showing him in the background on occasion.
* EtTuBrute: He assumes that Hot Shot betrayed him when in reality, the latter actually went to get help.
* EvilFormerFriend: Hot Shot's, though when they fight side by side [[spoiler:against Unicron]] he does seem to be warming up to him again.
* FallenHero: He is a former Autobot.
* FireForgedFriends: [[spoiler:After initially wanting to kill Hot Shot, he grants him an audience with Megatron, and their dialogue when fighting against Unicron indicates that their friendship may be restarting]].
* HeelFaceTurn: [[spoiler:Seemingly by the end, he's back with the Autobots again, or as at least forgiven Hot Shot]].
* IOweYouMyLife: Regardless of what he knows and doesn't know about the incident, Megatron truly did save him. After he joins the Decepticons, he never leaves or betrays them, no matter what amends are made. [[spoiler:This proves useful once the Autobots determine that Unicron is the greater threat.]]
* KickTheSonOfABitch: In "Past II", when he shoots Thrust out of the sky. Not to say that Thrust didn't deserve it, from what we [[{{Jerkass}} see of him]].
* MistreatmentInducedBetrayal: He believes that Hot Shot abandoned him to die earlier in the war. The reality is rather different.
* NobleDemon: He does grant Hot Shot an audience with Megatron.
* PoorCommunicationKills: He wasn't abandoned ''quite'' as completely as he thinks he was.
* RevengeByProxy: He takes Sideswipe hostage to get revenge on Hot Shot.
* ScarsAreForever: He has a giant scar over his old Autobot logo.
* ThatManIsDead: He does ''not'' like being reminded about his old allegiance, almost viewing it as a different life.
* WhatHappenedToTheMouse: Out of all the Decepticons that survived the show, Wheeljack is noticeably missing from ''Energon''. [[spoiler:It is likely that he reformed, given how he's forgiven Hot Shot by the end]].


[[folder:Rad White]]
!!Bradley "Rad" White:

Rad is the one who reactivated the Mini-Con ship while exploring some caves, and is inadvertently responsible for the restarting of the Cybertronian War.
* AudienceSurrogate
* BattleInTheCenterOfTheMind: He once helped [[spoiler:the Mini-Cons break Unicrons' mental hold on them.]]
* BewareTheNiceOnes: May only be a human, but he's got guts.
* PutOnABus: The comic pretty much ignores the kids once Simon Furman takes over writing duties.

->'''Voiced by:''' Mark Acheson, Creator/DavidKaye (when Megatron is possessed in ''Energon'')

A primal force of evil, his origins lost to the mists of time. He is the embodiment of all darkness and hate that lurks in the hearts of all beings.
* BackFromTheDead/ DeathIsCheap: This happens an incredibly frequent amount of times. You honestly wonder why the bots try to put him down again when he just gets back up.
** The first is implied at the end of ''Armada'', when his planet form is seen floating behind an unknown body. It's later confirmed at the start of ''Energon'' that he's just mentally inactive.
** The second and third attempts happen during ''Energon''. [[spoiler:He manages to reactivate his body form and possess Megatron, then dies a few episodes later at the hands of Optimus Supreme.]] Then after that he possesses Megatron yet again, [[spoiler:turning him into the incredibly large Galvatron in an attempt to recreate his body. This is thwarted when Galvatron hurls himself headfirst into a sun.]]
** A fourth and seemingly definitive example from the ''Cybertron'' comic: [[spoiler:Unicron frees himself from the Black Hole by hijacking a smaller Transformer's body, then recreates his body some time later.]] This time, he flees before Primus and the Autobots can defeat his weakened body.
* BrownNote: In the comics, Unicron speaking causes everyone pain.
* EldritchAbomination: As is tradition, though this helped to codify this part of his character.
* EvilSoundsDeep: Voiced by Mark Acheson in ''Armada'' (and a ridiculously small amount of ''Energon''). Downplayed when he's voiced by Creator/DavidKaye.
* GreaterScopeVillain: [[spoiler:To Megatron. While Megatron may be the BigBad of the show, Unicron far eclipses him in terms of threat, while being detached from the main show]].
* OmnicidalManiac: This is the trilogy that established this trope best for him.
* PlanetEater: Though unlike his debut appearance, he doesn't physically eat them, rather breaking the planet into smaller pieces and then devouring them. ''Energon'' shows this best.
* SciFiWritersHaveNoSenseOfScale: Not as bad as [[WesternAnimation/TransformersTheMovie his first appearance]] due to the fact that he rarely engages any Cybertronians physically, but when Thrust is perched/standing on his shoulder you do run into some fairly notable issues, notably the fact that he should theoretically be a speck from the distance we see him.

->'''Voiced by:''' Creator/PaulDobson (in ''Armada'')

An intergalactic drifter, Sideways transforms into a motorcycle. His consciousness is apparently housed within the smaller robot ''head'' that rides his alternate mode, which can split into two components.
* AntiVillain: [[spoiler:He was out to avenge his planet, turning to Unicron in hope that this would help him achieve his goals. TheDarkSideWillMakeYouForget soon kicked in afterwards, although by ''Cybertron'' he remembers again.]]
* AWizardDidIt: [[spoiler:It's implied Unicron's dark energy preserved him.]]
* BackFromTheDead: [[spoiler:In ''Cybertron'']].
* BadassBiker: Well, he is a badass ''bike''.
* BreakoutCharacter: He was cited by many as one of the few redeeming qualities of the first half of ''Armada''.
* CanonImmigrant:
** This characterisation of him was popular enough to get an appearance in ''WesternAnimation/TransformersAnimated'' and the film series (though just as a regular Decepticon).
** Technically, he first appeared in ''[[Anime/TransformersRobotsInDisguise Robots in Disguise]]'' with a toy from that show's line, though he was just an Autobot warrior.
* TheDarkSideWillMakeYouForget: [[spoiler:Servitude to Unicron caused him to forget that he was hoping to avenge his planet, and turned him into the {{Jerkass}} we see him as in ''Armada'']]. Subverted in ''Cybertron'' where he remembers again.
* DemotedToExtra: The Dreamwave comics just have him hanging around in the background, even when Unicron shows up.
* DigitizedHacker: It allows him to survive being sliced up.
* TheDragon: [[spoiler:To Unicron in ''Armada'' only]].
* DoubleReverseQuadrupleAgent: [[spoiler:In both ''Armada'' and ''Cybertron'', though both times he does have different agendas.]]
* {{Expy}}: Averted with his other appearances- possibly. [[spoiler:It's thought to be the same guy throughout the multiverse.]]
* EvenEvilHasLovedOnes: [[spoiler:It is implied that Unicron was [[DemonicPossession in possession of Sideways]] during ''Armada'', thus temporarily draining any sense of compassion the latter may have had. In ''Cybertron'', with Unicron destroyed, it is shown that Sideways ''does'' has the ability to care; in this case for the inhabitants of his destroyed world, including Soundwave and Laserbeak.]]
* EvilSoundsDeep: When played by Creator/PaulDobson.
* FauxAffablyEvil: In ''Armada''.
* GutturalGrowler: In ''Armada''.
* TheHeavy: After he appeared, he gradually shifted towards this, particularly as his boss was not shown for most of the series. Even when his boss appears, he serves as the representative and does most of the fighting.
* KickTheDog: He enjoys doing this. Particularly when it simultaneously helps his goals and hurts others.
* LaughablyEvil: In ''Cybertron''.
* ManipulativeBastard: He can quite easily turn people into his puppets when he needs to (not literally). Even in ''Cybertron'', he has a tendency to do this, as he [[spoiler:manipulates both sides again, taking advantage of their amnesia as a result of the Unicron Singularity]].
* MindScrew: [[spoiler:Unicron, Sideways, Sideways' Mini-Cons. It's kind of hard to tell where they each end and the others begin, which isn't helped by the shaky dub.]] Of course, [[InvokedTrope he enjoys running on this]].
* TheMole: [[spoiler:To Unicron, betraying the Autobots and then the Decepticons in the process]].
* MouthOfSauron: His boss [[spoiler:Unicron]] can talk, but to an extent Sideways still serves as this.
* NinjaPirateZombieRobot: A BadassBiker whose altmode is a CoolBike, who also exists as a DigitizedHacker. This also goes with the fact that he's a TransformingMecha. [[spoiler:Also implied that he is the same character throughout the whole multiverse.]]
* PlayingBothSides: [[spoiler:He initially screws over the Autobots by pretending to be a Decepticon, then in turn he screws the 'Cons over by leaking information of theirs to Unicron.]]
* {{Troll}}: He enjoys screwing people over, particularly when it helps him advance his plans.
* VillainDecay: In ''Cybertron''; He started out as a shadowy manipulator, playing both sides through sheer cunning. He became something of a joke in the later episodes, being outwitted and made a fool of by the humans (Though he gets better during his last few appearances). He even [[LampshadeHanging lampshades]] it at one point:
-->"I'm the one who's supposed to be pulling everyone's strings!"
* VillainousFriendship: With Soundwave in ''Cybertron''.
