- Depending on the Writer: Aside from the individual Decepticons, the faction itself has been portrayed differently across G1 media. They've been intrinsically evil machines out for universal conquest, as well as Well Intentioned Extremists who fought a corrupt government, but ended up becoming no better/even worse than them.
- For the Evulz: Both cartoon and comic Decepticons got started basically because they were bored and wanted a fight.
- Galactic Conquerer: They typically want to spread Cybertronian rule across multiple planets.
- Gladiator Games: In some continuities, the Decepticons were formed through these by Megatron.
- Meaningful Name: The IDW comics explains that the name "Decepticon" is taken from one of Megatron's rallying lines: "You are being deceived".
- Multiple-Choice Past: How the Decepticons formed varies among depictions: the Sunbow cartoon had them as the descendents of Quintesson military hardware, and the Generation 2 comic as descendents of the Leige Maximo (both times making them inherently evil), while the IDW and Dreamwave comics have them as normal Cybertronians swayed by Megatron for a single cause (IDW makes them out to be more noble... well, initially, anyway).
- Names to Run Away from Really Fast: With names like Ravage and Bonecrusher...
- Planet Looters: More often than not in the G1 mythos, they're on Earth to steal its numerous resources of energy for their own ends.
- Well-Intentioned Extremist: In the IDW continuity, the Decepticons were originally a protest group made up of lowly blue-collared workers who opposes the corrupt Autobot government, only to end up being disillusioned with the whole "peace through tyranny" stuff.
Function: Headmaster Commander
- "Kindness is no virtue... and cruelty is no vice."
- 0% Approval Rating: Marvel Comics Scorponok's approval rating didn't so much sink as drown when he let Starscream back into the fold. Had Optimus not decided to surrender as a show of faith, Shockwave's attempted coup probably would've gone unopposed.
- Alas, Poor Villain: Invoked with his death at the hand of Unicron in the Marvel comics.Scorponok: Huuuu... Puh-Prime? Did... Did... kuuuu... I do... good?Optimus Prime: Yes, old friend... You did good.
- Anti-Villain: Comic Zarak, who made the Decepticons leave Nebulos rather than allow harm to come to his daughter Lyra. While merging with Scorponok didn't do him any favours, as time went by he became increasingly doubtful and unsure of himself, not to mention proving willing to listen to Optimus after the guy saved his life (as Optimus does), and eventually went out fighting Unicron.
- Arch-Enemy: Usually, he's this for the similarly huge Autobot Headmaster, Fortress Maximus.
- A Villain Named "Z__rg": Lord Zarak, who's usually just as bad as the Decepticons even before they show up.
- Back from the Dead: In Regeneration One; his original pre-Headmaster head was left on Nebulos, which reactivated and ordered Nebulan scientists to reconstruct his original body.
- Beware My Stinger Tail: He turns into a giant scorpion with an electro-stinger in its tail.
- Big Bad: Scorponok sometimes acts as leader of the entire Decepticon faction (or at least a small group of them), and even when he isn't he usually acts as the big bad mastermind behind some scheme.
- Brainwashed and Crazy: In Transformers: Super-God Masterforce, Devil Z forced Scorponok (and by extension the Decepticons) under his control.
- Corrupt Corporate Executive: Zarak acted as one briefly in the Marvel comics under the alias "Mr Z", running the Z Foundation to recruit humans to destroy the Autobots (under the guise of being a charitable organisation devoted to the extermination of all Transformers on Earth).
- Disney Villain Death: Regeneration One sends him and Grimlock falling down a dark canyon. While Grimlock reappeared later on, Scorponok was seemingly not so lucky.
- Depending on the Writer: Scorponok and Zarak's portrayal wildly varies between continuities:
- In the Sunbow cartoon (specifically, "The Rebirth") he appears to be a lifeless Humongous Mecha controlled by Zarak, a green-skinned Nebulonian tyrant.
- in the Marvel comics Scorponok is a large (but not huge) sentient Decepticon who allies with Lord Zarak, a scheming Nebulan politician. Bob Budiansky depicted Scorponok as largely being your typical comic book villain, but Zarak as having some ethics. Furman depicted Zarak as being almost entirely in control, and when he wrote Scorponok in Regeneration One, Scorponok was essentially a James Bond villain.
- In The Headmasters, Scorponok is a small Cybertronian who controls a lifeless Transtector to become MegaZarak (and later BlackZarak), and is a total bastard who cares for no-one but himself, willing to destroy planet after planet in the name of ultimate power.
- Drone Deployer: Though often ignored by fiction, Scorponok's original toy comes with the semi-autonomous drone Fasttrack, which transforms into a car.
- Enemy Mine: He proved willing to team-up with Optimus. Eventually, at any rate, when Optimus told him Unicron was coming.
- Evil vs. Evil: Comics Scorponok vied for control of the Decepticons against Rabat. He eventually won via shooting the guy in the back. Later on, he has to deal with Shockwave and Starscream wresting control from him.
- Genius Bruiser: Though Scorponok is certainly a heavily armed and powerful Decepticon, he's also a cunning strategist. Some continuities hint that binary bonding with Zarak helped his intelligence grow exponentially.
- Genius Loci: One of his alt-modes is a city, though this is usually not seen by his smaller representations.
- Gravity Master: Downplayed; Scorponok's robot mode uses a fusion-powered anti-gravity gun. Try to guess what it does.
- Humongous Mecha: His bigger robot mode is city-sized in some continuities. His smaller mode (as Lord Zarak) is an inversion of the trope.
- Large and in Charge: How large and how much in charge he is though varies, but something that's consistent is that he's pretty big for a Cybertronian and is pretty high on the power chain.
- Legacy Character: In the Wings Universe continuity, Zarak's son Olin inherits Scorponok after he passes away, becoming the mech's new operator.
- Losing Your Head: He's a Headmaster. He tends to use the Scorponok name in his bigger mode and the Lord Zarak name in his smaller mode, though some have called him Zarak when in Scorponok mode.
- Paint It Black: Scorponok renames himself BlackZarak in Transformers: Super-God Masterforce, with a rebuilt and upgraded black Transtector.
- Power Pincers: Scorponok has large claws in lieu of hands, and he can use these to deliver crushing impacts.
- Scary Scorpions: One of his altmodes is a large robot scorpion controlled by Zarak in a cockpit.
- Secondary Color Nemesis: Scorponok is colored green, purple, black and orange in contrast with the Primary Color Champions of Autobots like Optimus Prime, Ultra Magnus, and his opposite number Fortress Maximus.
- Social Darwinist: Holds these beliefs in The Transformers: Monstrosity.
- Walking Armory: Even when he isn't the size of a city, he has guns all over his body, an electro-stinger tail, and powerful claws.
- Weaksauce Weakness: His Headmasters incarnation has a pretty big one - his chest window. One hit to it, and Scorponok would run away immediately.
- Your Size May Vary: Sometimes he is simply twice as tall as the average Decepticon, sometimes he's big emough to become a city.
- "Obnoxiousness is not a problem, it is an art."
- Cool Plane: A jet serves as one of Apeface's two altmodes.
- Everything's Better with Monkeys: One of his altmodes is a robotic gorilla. Of course, being a Decepticon, everything's not better when he's around, especially given Apeface's obnoxiousness.
- Evil Cannot Comprehend Good:"Yuck, noble Autobots make me want to puke." - in The Rebirth
- The Friend Nobody Likes: As an obnoxious and slobbish thug, he's not very popular among the other Decepticons (the one exception being his Horrorcon partner in crime, Snapdragon).
- Grievous Harm with a Body: Rampage ripped off one of his arms during one of the Decepticons' many Enemy Civil Wars. Apeface picked up his own arm and beat Rampage senseless with it.
- Jerkass: Even to fellow Decepticons, he's rude, loud and obnoxious.
- Losing Your Head: He's often a Headmaster, though ironically Apeface turns into a head himself in the Titans Return toyline (having been reimagined as an ancient Titan Master).
- Make Me Wanna Shout: His main weapon of choice (besides his own strength) is a semi-automatic sonic boomer gun, which emits powerful sonic blasts.
- Super Strength: In his ape mode, he's able to hit things far harder than in robot mode (his Tech Specs even give him a perfect 10 in Strength). Naturally, this is his go-to weapon in battle.
- Those Two Bad Guys: Together with Snapdragon, he makes a pair as the Horrorcons.
- Uncleanliness Is Next to Ungodliness: Apeface's Tech Specs note that he "never changes his lubricant so he smells like a grease-encrusted turboworm".
- Your Size May Vary: Usually, he's a normal-sized Decepticon whose head is formed by a human alien, but in Titans Return, Apeface is a human-sized Titan Master who transforms into his classic head (which can replace those of other Transformers).
Function: Assault Team
- "We're only halves of a whole, but double the trouble."
- Ascended Extra: Botcon 2015 gave him a new toy and made him the narrator for the main story for that year.
- Combining Mecha: He inverts the trope — his transformation involves him splitting into two separate altmodes.
- Depending on the Writer: His Bio in Dreamwave and his appearance in The Headmasters make him a Duocon, but his Marvel comics appearance makes him a Triple Changer. Timelines combines the two and says that he was originally a Duocon before being upgraded into a Triple Changer.
- Discard and Draw: In Timelines, Battletrap can no longer split into two different altmodes after an operation to permanently reunite his brain modules once they started to develop an immunity to each other. In return, however, he became a Triple Changer instead.
- Flawed Prototype: In the Dreamwave comics, Battletrap (and Flywheels) was the result of Shockwave's early attempts at creating a Transformer with more than one alt-mode, and failed as his consciousness was split between two vehicles.
- Literal Split Personality: Sometimes played straight in some stories where he is as a Duocon. In fact, he is the most sane of the two with Flywheels, as his own components get along well. Averted with other stories, in which they depict him as a Triple Changer.
- Vehicular Assault: A favorite battle tactic of his is smacking an enemy back and forth between his two altmodes before finally finishing them off.
Function: Assault Team
- "Believe in yourself, but only if you both agree."
- Cool Plane: One of his altmodes is an F-4 Phantom II jet.
- Depending on the Writer: He can split into two altmodes in continuities like Headmasters, G1, and Dreamwave, but in the Marvel UK comic he was more of a triplechanger, as well as the IDW continuity. Then in Titans Return, he's neither; instead being a Titan Master that forms a head for other robots.
- Flawed Prototype: In the Dreamwave continuity, he and Battletrap were among Shockwave's early experiments with creating Transformers with multiple altmodes, only to be deemed a failure when his consciousness was split across two separate altmodes.
- Half the Man He Used to Be: He had his top half shredded by Tesarus in the IDW comics.
- Killed Off for Real: In the Marvel comics and the G1 comics, possibly in the G2 comics. Killed in the IDW comics as well.
- Literal Split Personality: When he divides into his altmodes, they cannot agree on anything and are jealous of each other.
- Losing Your Head: In Titans Return, he's a Titan Master that turns into his original head. He doesn't have a larger body, but can act as the head for other toys.
- Mythology Gag: Thinking Fulcrum was a zombie is a callback to one of the few stories where Flywheels was actually important, City of Fear, where an ancient city was infested with zombies.
- Self-Duplication: Bizarrely, his Titans Return incarnation has him gift to whoever he's bonded with the ability to create a clone decoy.
- Tank Goodness: One of his altmodes is a howitzer tank of vague origin.
- We Hardly Knew Ye: When introduced in issue 7 of the IDW comics, Flywheels does the least to emphasize his personality, only showing he's kinda twitchy. He then disappeared for several issues before finally joining up with the Scavengers... and dying to the D.J.D. shortly after.
- "Just one look from me and you've lost."
- Adaptational Wimp: His Transformers Headmasters incarnation, while possessing the same powers as usual, is also something of a complete schmuck, whereas his western incarnations were more skilled and dangerous with them.
- Adaptation Species Change: Titans Return depicts Vorath as a small Cybertronian Titan Master as opposed to a Nebulan.
- Aliens Steal Cable: His attempts at contacting the other side have only succeeding in picking up old TV shows. Not that Mindwipe minds so much. He actually likes "My Mother, The Car".
- Bat Out of Hell: His altmode is a giant mechanical bat.
- The Chew Toy: In Simon Furman's run on G1. He gets shot by Starscream, conscripted to work for Shockwave via threats of death from Starscream, repeatedly fails to use those hypnotic powers of his, and the one time he does get them to work (on Soundwave, of all folk)... he's captured at gunpoint by Kup and "persuaded" to help smooth things over between both sides.
- Co-Dragons: In "The War Within: The Dark Ages", with Bludgeon and Bugly, for The Fallen.
- Compelling Voice: He is a hypnotist, so this comes with the territory.
- Evil Genius: He's skilled with his brainwashing techniques, and fills this role among the original Decepticon Headmasters.
- Hypnotic Eyes: He can use these to hypnotise lifeforms both mechanical and organic. Just one look is all he needs to put someone under his will.
- Losing Your Head: He's a Headmaster.
- Mad Scientist: In stories where he's a Nebulan, Vorath is a scientist who was expelled and discredited for illegal experiments. Naturally, he and the occult-minded Mindwipe don't see eye to eye.
- Mind Manipulation: Mindwipe's M.O. and deadliest weapon. Vorath also bestows this ability to whoever he's partnered with in Titans Return.
- The Paralyzer: He carries a vipor pistol that can freeze a 'bot for a good thirty minutes using a neuro-circuit paralysing liquid.
- Underestimating Badassery: He once tried hypnotising Grimlock, figuring the big guy would be an easy target. Grimlock just ignored it and decked him.
- "Keep shooting, eventually, you're bound to hit something."
- Adaptational Badass: His Headmasters incarnation is actually a capable shot, making his name very non-indicative.
- A-Team Firing: Misfire might actually be dangerous, if he could hit the broad side of the Ark. But instead, he fires several shots and misses every single one. It doesn't help his cause that Aimless doesn't care for picking up the slack in aiming.
- Comic Book Death: Another comic casualty of Unicron. Regeneration One has him inexplicably alive again, just so Scorponok can murder him for no reason.
- Cool Plane: His altmode is a Cybertronian jet with a top speed of 1600 miles per hour.
- Empathic Weapon: Aimless forms his weapon in most continuities.
- Goldfish Poop Gang: His IDW self is part of the Scavengers, alongside many other terrible and quirky Decepticons.
- Imperial Stormtrooper Marksmanship Academy: In his case, the inability to hit a target is a trait of the character.
- Losing Your Head: His Titans Return toy reinterprets Aimless as a Titan Master that forms Misfire's head rather than his gun. The Japanese release includes a larger Aimless figure that turns into his traditional weapon.
- Meaningful Name: In the IDW comics, he got his name after an incident with a machine gun, "a misunderstanding", and twenty dead Decepticons.
- Motor Mouth: His profile in the IDW comics states that he has ADHD.
- Mythology Gag: His gun in the IDW comics looks like Aimless, despite not being a Targetmaster in that continuity.
- "Too much destruction is never enough."
- Artistic License – Paleontology: Though Overkill is obstensively a tyrannosaurus rex, he has a nose horn that makes him closer resemble a ceratosaur.
- Ax-Crazy: Only fellow Blood Knight Frenzy rivals Overkill as the craziest and most violent of Soundwave's minions. He'll keep on attacking and destroying even when there's nothing left.
- Blood Knight: He has a tendency to indulge in... well, overkill when let loose on the battlefield.
- Harem Seeker: Oddly enough, in G.I. Joe vs. the Transformers he bragged about getting a girl-bot harem while trying to devour Hawk.
- Losing Your Head: In Titans Return, he's a humanoid Titan Master that becomes the head of larger robots. He comes with a robotic dinosaur similar to his original incarnation, however.
- Out of Focus: Overkill very, very seldom appears anywhere when compared to most of Soundwave's other minions.
- Power Incontinence: He sometimes fails to change his size when transforming from tape to dino mode, resulting in an action figure sized T-Rex.
- Sizeshifter: Overkill is among the few Transformers who explicitly change size when transforming. Said shifting [[Power Incontinence is also prone to glitching out, leaving him as a very tiny dinosaur.
- Super Strength: He's powerful enough to rip open the hull of a battleship and snap cars in half between his jaws.
- There Is No Kill Like Overkill: This is his philosophy; with powerful jaws, missiles that explode on contact, and a violent disposition, he uses more force than he really needs to when fighting foes. He gets so into it that he often forgets what his mission was, and/or looks like a fool as he keeps on fighting long after the fight's over.
- Those Two Bad Guys: He's often partnered up with fellow saurian Mini-Cassette Slugfest, their original toys even being packed together.
- Tyrannosaurus rex: Overkill's robot mode is shaped like a T-Rex (or at least what people thought a T-Rex looked like back then).
Pounce and Wingspan
Function: Infiltrator (Pounce), Data Processor (Wingspan)
- Pounce: "Terror is the stage on which I perform."Wingspan: "Knowledge is the most deadly weapon of all."
- Always Identical Twins: The two look identical in their robot modes, with only their alternate modes distinguishing them.
- Cats Are Mean: Pounce's alternate mode is a mechanical puma, and Pounce himself is far from a pleasant Decepticon, being anti-social, merciless, and wily.
- Evil Former Friend: In Transformers Headmasters, the two were friends with the Autobot Clones before allying themselves with Galvatron.
- Feathered Fiend: Wingspan's alternate form is a mechanical eagle, and he's just as driven and dangerous as his clone brother.
- In a Single Bound: Pounce's puma mode can jump a distance of 0.7 miles.
- No Sympathy: If an enemy pleads for mercy, Pounce won't give them the time of day.
- Sensor Character: Wingspan has chemical and infra-red sensors that allow him to detect resources and geographical data.
- Super Senses:
- Pounce has an improved sense of sight and smell, aiding him in his role as infiltrator. Said sight also gives him 99.4% accuracy with his anti-personnel bayonets.
- Wingspan gains superb vision when in his hawk form.
- "Life is worth saving only as long as there are enemies worth destroying."
- Adaptational Heroism: The Headmasters gives Sixshot far more redeeming qualities than his Tech Specs do, giving him a sense of honor and decency who never kills innocents or children in cold blood. For comparison, his Tech Specs claim his one redeeming trait is him speaking well of his victims.
- Adaptational Superpower Change:
- Transformers Headmasters, for whatever reason, gave Sixshot ninja abilities in addition to his alternate modes (of which he received an extra one in "Wingwolf"... which was obviously made via fiddling with the toy a bit).
- His Titans Return toy, thanks to toy guns becoming taboo in the modern era, replaces the gun mode for a submarine mode. It's totally not his gun mode turned upside down, we swear.
- Archnemesis Dad: He acts as this to his son, Quickswitch, who joined the Autobots to make good where Sixshot went bad.
- BFG: He can transform into a laser gun. Like Shockwave, he doesn't shrink when in this mode, and he can use jets to move around in gun mode.
- Challenge Seeker: Sees battle as a way to test himself against powerful opponents.
- Cool Car: One of his altmodes is an armed off-road car.
- Cool Starship: He can transform into a Cybertronian spaceship.
- Equippable Ally: Just like Megatron, Shockwave, and the Targetmasters, he can be fired by other Transformers while in gun mode.
- The Friend Nobody Likes: The IDW Decepticons all fear and despise Sixshot for the horrific nature of his function as a Phase Sixer. The only ones that come close to being his friends are the Terrorcons, who look up to Sixshot and want to be just as strong as he is.
- Heel–Face Turn: While he starts off as a nasty piece of work in Transformers Headmasters, he eventually comes to abandon the Decepticons and form a friendship with Daniel.
- Hero Killer: In The Headmasters, Sixshot kills Ultra Magnus in a duel on Earth.
- Hidden Depths: If he believes an opponent is worthy enough, he will face them in hand-to-hand combat to the death. Obviously, he's never lost such a contest, but he always speaks highly of those he's defeated in such a way.
- I Gave My Word: The only reason such an honorable warrior like Sixshot would continue to work for a deranged genocidal maniac like Galvatron was his sense of sworn-duty to Megatron.
- It's Personal: With Chromedome in Headmasters, thanks to killing his friends Jack and Abel. Also, later on, with Ultra Magnus, whom he killed.
- Losing Your Head: His Titans Return toy partners him with an ancient Titan Master named Revolver, who forms Sixshot's head.
- Loud of War: Sixshot wields two hypersonic concussion blasters, which are used in every one of his modes, though the wolf mode prefers the use of its razor sharp teeth.
- Made of Iron: At the end of Spotlight: Metroplex, Sixshot is crushed underfoot by the titular Titan. And he survives. Later comics established that Sixshot, as a Phase Sixer, is made Nigh Invulnerable.
- Meaningful Name:
- Sixshot, being a Six Changer, has six forms — his robot mode, a tank, a gun, a spaceship, an off-road vehicle, and a winged wolf.
- The IDW continuity gives his name additional meaning as a Phase Sixer — as the sixth phase of Megatron's infiltration protocol, he's sent in to completely raze a given planet and eliminate any remaining scraps of resistance.
- Must Make Amends: His Japanese continuity version decides, after his turn to good, to try and find a way to bring back Chromedome's friends.
- Mythology Gag: His Titan Master partner, Revolver, looks like Jack, whose death Sixshot caused in Headmasters.
- Never Speak Ill of the Dead: His one redeeming trait is his admiration for the opponents he's killed, which are often those he deemed worthy opponents.
- Noble Demon: Sixshot, in The Headmasters only serves the Decepticons out of a sense of sworn duty to Galvatron, and is actually a principled, decent and honorable warrior who does not kill children or innocents in cold blood. This hidden decency allows him to befriend Daniel later on, resulting in a Heel–Face Turn.
- One-Man Army: With the function of Solo Transformer Assault Group and six transformations, Sixshot is perfectly capable of holding his own against far more numerous opponents.
- Out of Focus: Unusually for a Merchandise-Driven franchise and an ambitious toy, Sixshot made only a single appearance in the Marvel comic and the Sunbow cartoon (but for the latter, he sure made it count). It wasn't until IDW came along that he got a starring role.
- Person of Mass Destruction: In the IDW comics, Sixshot is one of Megatron's "Phase Sixers", a trio of extremely powerful Decepticons who are expected — and perfectly capable — of razing entire planets to the ground whenever they see action.
- Savage Wolves: Sixshot has a mechanical winged wolf as one of his transformations, and he's as cruel, cunning and destructive as any Decepticon comes.
- Super Soldier: One gets the impression that this is Sixshot's role in the Decepticon hierarchy. It's even more blatant in IDW, where he is explicitly created as a Phase-Sixer.
- Tank Goodness: One of his many transformations is of a Cybertronian tank.
- Worthy Opponent: If he speaks well of his victims, he must consider them this to some degree.
Function: Swamp Warrior
- "Autobots are like bad fuel - weak and greasy."
- Buffy Speak: He refers to his gun as a "Soften Up" gun rather than its given name, because he can't pronounce it.
- Character Tics: Grinding his teeth together in crocodile mode.
- Corrupt Corporate Executive: Grax, Skullcruncher's headmaster partner, tried getting him to eat his business rivals. It worked, but Skullcruncher didn't like organics (not very filling).
- Dumb Muscle: He's tough, and he's strong, but he's incredibly slow and stupid
- I'm a Humanitarian: Skullcruncher has eaten both Nebulans and Transformers. He's not really fond of either (Nebulans aren't very nutritional, and as for Autobots... see his quote).
- Losing Your Head: He's a Headmaster.
- "Expect betrayal and your friends won't disappoint you."
- Absurdly Sharp Blade: The plates down his back double as this.
- Conspiracy Theorist: He's absolutely sure all the other Decepticons are plotting against him behind his back.
- Dumb Muscle
- Mighty Glacier: Strength score of 9, Speed score of 1.
- The Spiny: Supposedly. in the IDW comics, Ultra Magnus steps on him with no bad consequences.
Function: Air Defense
- "The only way to survive a duel with me is to not show up."
- Dirty Coward: His definition of a "duel" is shooting his enemy from behind and at a distance.
- Empathic Weapon: Caliburst.
- Miles Gloriosus: He boasts of his skill as a marksman, but is nowhere near as good as he thinks.
- Only Sane Man: When your teammates are Triggerhappy and Misfirenote , coward or no, you're a more effective and stable teammate.
- The Starscream: His Japanese G1 incarnation tried betraying Megatron, resulting in their fleeing into space to avoid his wrath (which is why they didn't show up until after Galvatron was defeated).
- "If it doesn't get you dirty, it's not worth doing."
- Hair-Trigger Temper: It doesn't take much to set him off.
- Losing Your Head: He's a Headmaster.
- The Pig Pen: When he's not in battle, he prefers to lounge around in his extremely messy living quarters.
- Undying Loyalty: To Lord Zarak. It is considered his only redeeming feature.
Function: Terrorcon Leader (Hun-Grrr), Terrorist (Rippersnapper), Sentry (Sinnertwin), Foot Soldier (Blot), Shock Trooper (Cutthroat)
- Hun-Grrr: "Eat only what you need - destroy the rest."Rippernapper: "Autobots are an error I intend to correct."Sinnertwin: "The sound of ripping metal is music to my audio modules."Blot: "I'm not as bad as I look - I'm worse."Cutthroat: "Compassion is the currency of losers."
- "Awesome McCool" Name / Punny Name: Sinnertwin
- Berserk Button: Hun-Grrr was in a good mood, he offered some energon chips to his boss, Bludgeon, due to a complex frame-up, Bludgeon believed Hun-Grrr to be a traitor. Hun-Grrr was more pissed off that his generosity was refused.
- Big Eater: Hun-Grrr.
- Comic Book Death: Another bunch of Starscream's Underbase rampage victims.
- Dumb Muscle: Abominus is so destructively dumb that a timer needs to be set before the Terrorcons merge. However, there was this one time during the "Hate Plague" episode where he manages to beat Computron (because the latter "thinks too much).
- Extreme Omnivore: Hun-Grrr can eat almost anything and spits it out as missiles and weaponry.
- Fat Slob: Blot is not really fat in fat standards. But he's still too dumb to do anything about it.
- The Knights Who Say "Squee!": To Sixshot (in IDW comics continuity).
- Multiple Head Case: Hun-Grrr and Sinnerwtin's alternate modes both possess two heads. This trope is played all the way straight with Sinnertwin, whose heads appear to possess distinct personalities and voices and even argued with each other at one point over who got to kill an Autobot. It's downplayed in Hun-Grrr's case, as his heads speak in unison with a singular voice and neither appears to possesses any distinct sense of self.
- The Pig Pen: Blot constantly leaks some sort of disgusting fluid.
- Psychopathic Manchild: Rippersnapper takes his massive inferiority complex out on his Autobot enemies.
- The Psycho Rangers:
- Spell My Name with an "S": The Terrorcon leader's name has been spelled as Hun-Gurrr, Hun-Grr, Hun-Garr, Hun-Grrr, and Hun-Gar across various official sources.
- Verbal Tic: "Let's all speak like Grimlock!" (On and off during G1 cartoon.)
- Undying Loyalty: Because his hygiene problem causes others to keep their distance from him, Blot shows this towards anyone who at least pretends he's worth something, especially Hun-Grrr.
- Weaksauce Weakness: Sinnertwin's afraid of small, furry animals despite being a scary two-headed orthrus.
- "Have gun, have fun!"
- Ax-Crazy: He's a drooling idiot who laughs maniacally when he fires his (many) guns.
- Blow You Away: Triggerhappy's compression cannon fires compressed air at forces strong enough to crush armor. When Blowpipe is a Titan Master, this ability is imbued on whoever he combines with (not just Triggerhappy).
- Cool Plane: Triggerhappy transforms into a Cybertronian jet, which Blowpipe is able to drive.
- Depending on the Artist: While his box-art illustration (shown above) and original toy show him with a visor and a mouth, his fiction appearances and Titans Return toy instead give him uncovered eyes and a mouthplate.
- Empathic Weapon: As a Targetmaster, Triggerhappy's compression cannon is the altmode of Blowpipe.
- Freudian Excuse: It's been rumored that as a scared novice, Triggerhappy actually survived his first few battles by firing madly in all directions, and permanently adopted the technique soon after.
- Leeroy Jenkins: Triggerhappy's idea of a battle strategy is "wave guns around randomly while firing really fast". This severely annoys the more calm and strategic Blowpipe.
- Losing Your Head: In Titans Return, Blowpipe is instead a Titan Master that transforms into Triggerhappy's head.
- Meaningful Name: The Decepticon named Triggerhappy is Trigger Happy? You don't say!?
- Trigger Happy: Well... yeah. He loves the sounds his guns make when they go off, so much so he fires them while laughing uncontrollably.
- "My pleasure with my enemy's pain comes."
- Damn You, Muscle Memory!: When bonded to Monzo he is, forgo his weapons in favour of wrestling he does, because able to let go of his past Monzo isn't.
- The Dragon: In Headmasters, he's one of Scorponok's top minions. Well, for a given value of "top".
- In a Single Bound: Capable of leaping eight miles in a single go, he is. According to his Universe profile, at least. Never really been depicted elsewhere, it hasn't.
- Talkative Loon: Occasionally blows his cover by announcing his presence before pouncing.
- Verbal Tic: Backwards he talks. Unless written by Simon Furman, he is.
- Your Head Losing: A Headmaster he is.
- "The greater the foe, the sweeter his fuel."
- Bat Out of Hell: His Pretender shell
- Killed Off for Real: IDW comics.
- Our Vampires Are Different: He's a giant alien robot who feeds on the energy of other robots because it both increases his strength and because his specialised armor will swiftly drain him of energy if he doesn't.
- Paranoia Fuel: In-Universe. Bomb-Burst is regarded as a dark and terrifying legend among Autobots for his preferred methods of silently hunting them down and picking them off, one by one, leaving behind mangled corpses sucked dry of fuel that are only found in dawn's light.
- Weaksauce Weakness: His optics are over-sensitised to light, so he shuns brightly lit places and sunlight. The fact his Pretender shell will rapidly deplete his own energy reserves if he doesn't feed often enough arguably counts.
- "The greatest power is the power to control."
- Co-Dragons: In The Dark Ages, he's one of The Fallen's goons, alongside Bludgeon and Mindwipe.
- The Paralyzer: His stingers are capable of subduing some 'bots. In extreme cases, it causes permanent paralysis.
- "A cunning smile is more devastating than the fiercest weapon."
- Adaptational Heroism: While his toy bio solicits him as a crazy sadist, his main appearances in fiction (Marvel UK and IDW) cast him as a Noble Demon at worst and an Anti-Hero at best. Beyond that he's often just background filler and presumably no worse than the average Decepticon.
- Anti-Hero: Post-Heel–Face Turn in Marvel UK continuity. Somewhere between a Type II and a Type III (arguably a type IV in his revenge arc).
- Anti-Villain: Before Heel–Face Turn in UK comic continuity.
- Ax-Crazy: His Dreamwave incarnation supposedly went nuts a long time ago, becoming a savage monster.
- Blood Knight: (Marvel UK) As he says to Springer: "I'm a Decepticon warrior! The need to fight is in my oil." However, he comes to value the fight for more than its own sake whilst defending humans from his former Decepticon comrades.
- Cruel Mercy: Stops Springer from killing Bludgeon, Stranglehold and Octopunch as he reasons "denying them their 'warrior's death' is the worst fate I could think of".
- Defector from Decadence: Marvel UK. Breaks away from the Mayhem Attack Squad with his Pretender comrade Catilla and joins up with the remnants of the Wreckers to form the Survivors. Later comes to admire and value human life.
- Enemy Mine: Teams up with the Wreckers to fight Megs and Galvy in Time Wars.
- Even Evil Has Standards
- Fire-Forged Friends: With Springer and the Wreckers as a result of their Time Wars team-up.
- Heel–Face Turn: Again, in Marvel UK continuity. Joins the Autobots and comes to appreciate the value of human life; however, he still retains his Decepticon ruthlessness when fighting his former comrades. See Cruel Mercy and Roaring Rampage of Revenge.
- Noble Demon: In the Marvel UK continuity, he disobeys his orders to "kill any Wreckers left standing" after fighting with them against Galvatron and Megatron in Time Wars.
- Out of Focus: Carnivac has sadly never regained the focus he got in the Marvel UK days.
- Proud Warrior Race Guy: Marvel UK.
- Roaring Rampage of Revenge: Takes out most of the New Mayhem Attack Squad after they kill his comrade, and fellow Defector from Decadence, Catilla. However, he spares Bludgeon, Stranglehold and Octopunch in the spirit of Cruel Mercy.
Function: Aerial Assault
- "Things are never as bad as they seem - usually they're worse."
- Combining Mecha: with Dreadwind. His Power of the Primes toy is also a combiner.
- "The price of victory is never too high."
- Killed Off for Real: IDW comics. Hot Rod shoots him square in the chest, he bursts into flames and plummets down a mountain, shattering to pieces on impact.
- The Mole: Undercover as an Autobot AND as a Decepticon, so he can get benefits from both sides. He even uses two different robot modes (humanoid as an Autobot, eagle-like as a Decepticon) to not be discovered.
- Obviously Evil: After killing him, Hot Rod admits that his treachery was staring him in the face.
- Playing Both Sides: In his only Marvel UK appearance, he uses his dual identities to manipulate Optimus and Scorponok.
Function: Air Defense
- "Fear is a friend whose presence is felt long after he's left."
- Combining Mecha: with Darkwing. And in Power of the Primes, he forms the limb of a combiner.
- The Eeyore: In the running against Dead End for Most Depressing Outlook In The Decepticon Army.
- "Leaders are for fools who need to follow."
- The Berserker
- Berserk Button: Throws a fit if he's given orders.
- Losing Your Head: He's a Headmaster.
- Mix-and-Match Critters: His beast form is depicted as a wolf with bat wings and a reptilian tail.
- Too Dumb to Live: In the Marvel comics, he repeatedly picks a fight with Grimlock. In the final issue, it finally comes back to bite him, when Grimlock punches straight through his chest.
Function: Naval Assault
- "Ashes to ashes, rust to rust."
- Comic Book Death: Dies fighting Unicron, when the guns he's manning (meching?) overload and explode.
- Fish People: His Pretender shell. It even appears as if it was wearing a iron mask.
Function: Firestorm Trooper (Cindersaur), Warrior (Flamefeather), Cryptologist (Sparkstalker)
- Cindersaur: "Crash and burn... and burn... and burn."Flamefeather: "The only good Autobot is a deactivated Autobot."Sparkstalker: "The smallest details reveal the largest secrets."
- Ax-Crazy: Cindersaur and Flamefeather, much to Sparkstalker's chagrin.
- The Berserker: Cindersaur and Flamefeather, again, the former because of his unbelievable idiocy and the latter because he's so violent that even the Decepticon military academies didn't want him.
- The Cracker: Sparkstalker, a brilliant cryptologist and extremely stealthy, sublte hacker. Instead of using those talents, he's stuck babysitting a driveling idiot and a rage fueled hate machine.
- Breath Weapon
- Evil Has a Bad Sense of Humor: Cindersaur. "Hey guys, watch Fizzle sizzle!"
- Gonk: They are drawn with a very high degree of toy accuracy in robot mode in the Marvel comics. Unfortunately this makes them all stumpy, chubby-looking dwarfs compared to more the proportionally humanoid designs of, say, the Seekers.
- Hair-Trigger Temper: It's said that Flamefeather's greatest achievement in life was talking to someone for a full minute without going into a frothing rage.
- Killed Off for Real: Sparkstalker was accidently incinerated by the idiotic Cindersaur in a Friend or Foe incident.
- Back from the Dead: In the Regeneration One comics.
- Only Sane Man: Sparkstalker
- Pyro Maniac: By definition, but Cindersaur in particular.
Function: Ground Trooper
- "Smash all that stands and trample the rest."
- The Bully: He's an asshole who picks on other people, even other Decepticons. Also a pun.
- Kill It with Fire: Flamethrower tail-gun for robot mode, burning smoky breath for beast mode.
- A Load of Bull
- Losing Your Head: He's a Headmaster. He later got his head blown off his shoulders, which was decidedly more fatal.
- No Accounting for Taste: Why was Needlenose dating this guy again?
- Shout-Out: While called a bull, his beast mode design owes a fair bit to the 'terror dogs' of Ghostbusters (which predated his release by two years).
- Uncleanliness Is Next to Ungodliness: Not just gross but deliberately repulsive. He's proud about the fact that he can't remember his last bath. He's also extremely bad-tempered and abusive.
- Your Head Asplode: In the IDW comics thanks to an Autobot inhibitor/deterrence chip that was actually Soundwave's doing.
Function: Terror Trooper
- "Sow the seeds of fear and victory is yours."
- An Arm and a Leg: IDW comics. When he goes to Bludgeon about the Autobots having infiltrated the base, Bludegon's merged with his pretender shell, and the psychic shock causes him to go crazy and slice off one of Iguanus's arms and legs. He bleeds to death from the injury.
- Becoming the Mask: Ever since he gained a reptilian Pretender shell, he's been obsessed with them. His bio calls it 'misguided camaraderie.'
- Cool Bike: He transforms into a bike that is a dead-ringer for a Command & Conquer recon bike.
- Eldritch Abomination: In Regeneration One. The Autobots have no idea what the shadow-leeches are until they isolate one, analyze it, and discover to their horror that it used to be Iguanus...meaning that the other leeches used to be everyone else.
- Narcissist: Swoons over his own freaky reptilian Pretender shell.
- Reptiles Are Abhorrent: A big creep in more ways than one. Even his bio calls him hideous, loathsome, and a monster.
Function: Aerial Warrior
- "Get hip or get hit!"
- Alien Arts Are Appreciated: Finds Earth's fads and trends fascinating. So far, that means being a video game nerd.
- Crying Wolf: Does this in the appropriately named Marvel UK strip Cry Wolf; his comrades don't take it well; Carnivac (HeelFaceTurned Decepticon with wolf Pretender shell and alt mode) uses Needlenose's fear and paranoia to his advantage, making the paranoid Decepticon the first target of his Roaring Rampage of Revenge.
- Empathic Weapons: Sunbeam and Zigzag.
- Evil Counterpart: Needlenose's interest on Earth culture makes him very similar to Jazz.
- Jerkass: In The Transformers: Robots in Disguise.
- Kill It with Fire: He has a flamethrower in the IDW comics.
- Mauve Shirt: The Transformers: Robots in Disguise, he keeps showing up doing odd jobs for the Decepticons or for himself, from enforcing the peace, to hiding Dirge, to beating up civilians, to advocating that the Autobots not kill Megatron.
- The Mourning After: Needlenose never got over Horri-Bull's death and blamed the Autobots for it because he never learned that it had actually been detonated by Soundwave.
- No Accounting for Taste: Why the chic, would-be trendsetter was dating the abrasive, phenomenally gross bully is anyone's guess.
- Robo Family: His brother is the Autobot Tracks. Amusingly it's the Autobot who's the elitist snob. Unlike other siblings in the franchise there's no clear indication of what makes the two of them related.
- Sibling Rivalry: With his brother Tracks, as one is an Autobot and the other joined the Decepticons.
Function: Ground Assault
- "Nothing lasts forever... so why not destroy it now?"
- The Berserker: Violent to a fault, too. Other Decepticons have to dive for cover because he shoots everywhere and lets his hit count do the talking.
- The Bully: Basically a big ol' jerk that tries to pick on anyone he thinks is weaker than him, which usually comes back to bite him in the aft.
- Dumb Muscle: His Strength, Endurance, Courage, and Firepower levels are quite high. His intelligence is only slightly better than Sludge, widely considered the dimmest bulb among the Dinobots.
- Empathic Weapons: Tiptop and Heater.
- Mugging the Monster: Quake tends to underestimate people, and then tends to get his butt kicked. Most notably, he mocked the relatively diminutive Tigatron during the 3H comic era, and got his face vaporized off for his effort.
- Purple Is Powerful: A powerful brute who turns into a magenta-purple tank.
- Tank Goodness: More like Tank Badness due to being such a bully.
- They Killed Kenny Again: Quake has a bad habit of dying a lot.
- Wall Crawl: His tank treads can exude an adhesive that allows him to scale vertical surfaces.
- "Destruction has a beauty all its own."
- Dirty Coward: He prefers to remain in his Pretender shell for the bulk of a battle, only coming out when there are nothing but wounded Autobots who are too weak to fight back.
- For the Evulz: He's been known to blast the kneecaps out of a fleeing Autobot, just so he can enjoy the sight of them flailing around in agony.
- Ineffectual Sympathetic Villain: Transformers: Wings of Honor he's not that effective or smart. When chased down a hall way, he eptied several clips into the wall behind him, reasoning that the pursuers have to come around the same corner and get shot (his companion said it was stupid, as they wouldn't run into a hallway riddled with gunfire).
- Red Shirt: In IDW comics he's killed when fighting Thunderwing. Adding insult to injury, everyone else in that fight turned up alive again later. Roadgrabber didn't.
- The Sociopath
Function: Seacon Team Leader (Snaptrap), Underwater Excavations (Nautilator), Undersea Terminator (Overbite), Undersea Reconnaissance (Seawing), Amphibious Assault (Skalor), Underwater Demolitions (Tentakil), Undersea Warrior (Piranacon)
- Snaptrap: "Broken Autobots never mend."Nautilator: "Blame someone else before they blame you."Overbite: "There are two kinds of creatures: predator and prey."Seawing: "The darkest depths reveal the darkest secrets."Skalor: "I stink, therefore I am."Tentakil: "Embrace your enemies... until they're terminated."Piranacon: "Underwater, no one can hear you scream."
- Animal Motifs: All of them transform into sea animals.
- BFS: Piranacon wields an incendiary sword, formed from Snaptrap's.
- Blood Knight: Snaptrap's favorite part of the hunt is the kill.
- Butt-Monkey: Nautilator. If not for the Seacons being relatively unknown, one would believe Futurama's Zoidberg is an Expy of him.
- Also a meta example: Nautilator was excluded the first time the team was sold as a multi-pack. Later multi-pack releases do include him.
- Combining Mecha: They form Piranacon.
- Comic Book Death: The entire team is frazzled during the Underbase saga. Adding insult to injury, in the US comics this was but a few issues after they'd been introduced.
- The Determinator: Every Seacon (even Nautilator) shares this trait, which results in Piranacon becoming endlessly relentless.
- Egomaniac Hunter: All of them, and taken to such an extreme in Piranacon that Snaptrap had to install an automatic timer to insure that they'd separate after a certain amount of time to prevent them Piranacon from hunting all the time.
- Empathic Weapon: Piranacon's a "Scramble City" Combiner with special hands. So any one of his limbs can become his gun.
- Faux Affably Evil: Tentakil, so very much.
- The Klutz: Nautilator, full stop.
- Leeroy Jenkins: Nautilator. His physical abilities are certainly impressive...but he's such a moron that the rest of the Seacons end up Face Palming every time he gets himself in trouble and they have to rescue him.
- The Load: The rest of the Seacons feel this way about Nautilator, since they've repeatedly had to fish his chassis out of the depths whenever he gets himself lost. Whenever they form Piranacon, the Seacons always make Nautilator serve as their weapon, rather than let him form a body part, so that they don't have to mentally merge with him. When Nautilator is allowed to form one of Piranacon's limbs, the gestalt's performance is noticeably impaired. As Snaptrap says, if Nautilator didn't occasionally find something useful when he got lost, they would have left him to rust a long time ago.
- Never My Fault: Nautilator is, according to his tech specs, a "stumbling, bumbling amphibious foul-up." Of course, whenever he's called out for his screw-ups, he always tries to shift the blame to someone else.
- No Respect Guy: Nautilator
- The Paralyzer: Seawing has rays which can temporarily freeze up a Cybertronian's body. They even work on Galvatron.
- The Pig Pen: Skalor DOES NOT CARE about what other Decepticons think about his lack of personal hygiene.
- The Red Baron: Snaptrap is known as "The Butcher of the Bogs", after an incident when he ambushed and killed a group of Autobots in the Toxic Sludge Swamps on his own.
- Serial Killer: Tentakil is oh~so~smooth.
- The Starscream: Seawing, inside the team.
- Super Drowning Skills: Nautilator tends to rust easily, he can't navigate to save his spark, and he has trouble swimming. And he's a member of the Decepticons' underwater strike force.
- Uncleanliness Is Next to Ungodliness: Skalor, a disgusting slob who is as unkind as he is unsanitary.
- The Worf Effect: Piranacon is claimed to be a nigh-unstoppable, terrifying murder machine. Galvatron once defeated him handily.
Function: Siege Warrior
- "Those who stand against me shall soon fall before me!"
- Attention Deficit... Ooh, Shiny!
- Depending on the Writer: Thanks to "Monstercon From Mars", writers are torn between having Skullgrin be a mindless brute obsessed with destruction and violence (per his tech specs) and his comic portrayal, who was smart, obsessed with fame and immersing himself in human culture (including becoming an actor), and showing kindness to humans. Dreamwave's profile books went with the notion that he's normally the latter, which annoyed his bosses, who programmed his Pretender shell to make him the former.
- Establishing Character Moment: Transformers #46 (Monstercon From Mars), which has Skullgrin embrace Earth and become a movie star, showing him as someone who was far more than a bruiser and who was interested in fame as an actor and capable of kindness towards humans.
- Killed Off for Real: G2 has him killed when his spaceship blew up in orbit, and IDW comics when the Wreckers tossed a grenade at him and Bomburst, blowing them up.
- People in Rubber Suits: In-Universe example. He used his Pretender shell to become a star in monster films.
- Pet the Dog: Forms an actual friendship with an actress when he was taken to become an actor, and saves her later on. His teammates make fun of him for it.
Function: Assault Warrior
- "Stealing isn't a crime, getting caught is."
- Full-Boar Action: His pretender shell and regular alt-mode are both boars.
- Jerkass: Snarler is utterly unwilling to lift so much as a finger to help allies unless he's absolutely certain it'll benefit him.
- Mighty Glacier: Snarler's strong and durable, but he's speed isn't much to write home about.
- This Is a Drill: His regular beast mode has a drill-snout.
Function: Aerial Assault
- "Respect your foes' abilities as you would your own."
- Awesome Mc Cool Name
- The Cameo: He appears in Transformers Armada where he is the sole survivor of a dead cybertron in another Universe.
- Combat Pragmatist: In the Marvel comics. When Carnivac comes for them, Spinister snipes him instead of fighting him hand to hand. When the Mayhems resolve to go down fighting, he opts to run.
- Empathic Weapons: Hairsplitter and Singe.
- Enigmatic Minion: That's his bio in a nutshell, he's a mystery to all those around him, no one knows his motives. In the Regeneration 1 comics, all the Decepticons opt to work for Scorponok after he kills Misfire, while leaving, Spinister relays the information to Soundwave, for his own reasons.
- Genius Ditz: In the IDW continuity he's an expert surgeon despite being too dumb to count to three.
- Killed Off for Real: Carnivac killed him in the Marvel comics (the comics in question had questionable continuity, and all future appearances in that continuity keep him alive), and in Transformers Armada, he was killed by Unicron.
- Mythology Gag: His IDW personality, being a bit crazy in the head and all, hearkens back to Transformers Armada, where Optimus prime meets an insane Spinister on a dead Cybertron.
- The Quiet One
- Too Dumb to Live: In the IDW comics.
- Weak, but Skilled: He has some impressive moves, but is seriously lacking in physical strength.
Function: Interrogator (Beastbox), Translator (Squawktalk)
- Beastbox: "Speak now if you intend to ever speak at all."Squawktalk: "If you have nothing interesting to say, say it anyway."
- Area of Effect: If he's not careful, Squawkbox's sound-based attacks can affect any of his fellow Decepticons within the vicinity.
- The Brute: Beastbox. And someone thought he was a good choice for interrogation. His bad temper usually means he beats his prisoners to death, without even taking down what they're trying to say.
- Killer Gorilla: Beastbox, hands down.
- Feathered Fiend: Squawtalk.
- Gale-Force Sound: Squawkbow can produce a disorienting and physically damaging sound show.
- Motor Mouth: Squawktalk can request a cracker in trillions of languages.
- Remember the New Guy?: In the IDW comics, Soundwaves cassettes all are shown a little back-story, Ravage, Laserbeak and Buzzzsaw already work for him, Rumble and Frenzy get retooled to work with him, and he forces Ratbat into a cassette body, but Squawkbox just shows up out of nowhere helping to deliver weapons to the newly formed Decepticon army.
- "Place brawn before brains and victory is yours."
- Giant Crustacean: His alternate form is a huge crab beast. Most people confused it for a bipedal cobra but pincers, but that's not the case.
- The Brute: While not unintelligent (the opposite, in fact), he prefers to rely on sheer force to win. His Headmaster parter, Lokos, is trying to persuade him to use his untapped intellect to get ahead.
- Losing Your Head: He's a Headmaster.
Function: Undersea Warfare
- "Conquer the seas and the rest will fall!"
- Becoming the Mask: His Pretender shell has engendered a very real respect and care for sea life.
- Berserk Button: Submarauder hates company in general, but people — human, Autobot, even Decepticon — interfering with the creatures he is so fascinated with really stirs him up.
- Forgets to Eat: Submarauder apparently can get so caught up in his studies and meditations that he forgets to return to base for refuelling.
- Genius Bruiser: The savage, raging berserker is actually, at heart, a reclusive and scholarly intellectual who finds great satisfaction in observing sea life and pondering the ocean's mysteries.
- Hidden Depths: Let's face it, "easily-angered Decepticon warrior" and "scholar with a genuine love for sea creatures and the ocean" don't exactly go together at first glance.
Function: Data Collector (Crankcase), Combat Assault (Ruckus), Air Defense (Windsweeper)
- Crankcase: "Things are never as good as they seem."Ruckus: I take a licking and keep on kicking."Windsweeper: "Uninvited guests soon become smoldering wrecks."
- The Cynic: Crankcase is always in a bad mood.
- Determinator: Ruckus, in the Marvel comics, supposedly once got reduced to nothing more than his voicebox, and still did what he could to get a message to Megatron.
- Humongous Mecha: In the IDW comics, Crankcase finds one in a crashed spaceship.
- Giver of Lame Names: Crankcase in the IDW comics
- Killed Off for Real: Ruckus (IDW comics)
- Loud of War: Ruckus
- Made of Iron: In the IDW comics, Crankcase been pummeled, electrocuted, and previously had a chunk of his head blown off. His original appearance had him survive an encounter with Thunderwing, a being who killed most of his squad (including Ruckus) and leveled at least two planets.
- Neat Freak: Windsweeper, along with a bit of Terrified of Germs, to the point of shooting anything else in the air: planes, birds, insects, leaves, even clouds. He can be defeated by throwing garbage at him, as being dirty causes him to become irrational enough to literally blow a fuse.
- Not-So-Harmless Villain: Crankcase was originally a scrawny, nerdy, constantly picked-on fuel spill janitor before getting an upgraded body complete with shoulder cannons.
- Only Sane Man: Crankcase shares this role with Krok in the scavengers arc of the IDW comics.
- Skewed Priorities: In Spotlight Megatron, Windsweeper wonders if they should stop Starscream and Megatron from killing eachother because they were making a mess. Skywarp threatens to Tele-Frag him if he tries.
The Air Strike Patrol
- "The more tightly you hold a secret, the more we like ripping it a way."
- The Chessmaster: Tailwind, the only one of the group who stands a chance of success in scheming to take control of the team because he's both subtle and manipulative.

- Dirty Coward: Nightflight, though he'll argue he's actually a Combat Pragmatist.

- The Mole: In an Evil vs. Evil scenario. They faked loyalty to Scorponok, but actually worked for Megatron.
- Mugging the Monster: They attack an oil refinery and run into Hector Dialonzo. They think he's just another flesh creature. They don't survive, as it turns out he's the superhero Dynamo.
- Only Sane Man: Whisper, who lacks any real flaws aside from being a Decepticon squad leader.
- Opportunistic Bastard: Nightflight again. He's the sort of person who would prefer to steal pocket change rather than put in the effort to rob a bank because the change was easier to take.
- The Starscream: Everyone to Whisper. That's right, his entire team is trying to usurp his command. Fortunately for Whisper, Tailwind is the only one who could actually pull it off... if he ever decides the time is right to strike.
- The Stoic: Tailwind. He says the least of anyone in the team, but that just means he's more likely to get away with his plots.
- Teeth-Clenched Teamwork: The only way this bunch of backstabbing, squabbling rowdies get anything done.
- Too Dumb to Live: Storm Cloud. Usually, attempting to stage a coup in a villain's army requires a degree of subtlety, restraint, or skill. Storm Cloud has none of these and will loudly announce plans to overthrow Whisper in public. In front of Whisper.
Function: Aerial Defense
- "My price is too high and you're going to pay."
Function: Electric Warrior
- "To know your own limits, you must first know your foe's limits."
- Arrogant Kung-Fu Guy: A master of the Cybertronian martial art of Metallikato, and prone to preceeding his sentences with a heartfelt "Fools!"

- Clothes Make the Legend: Whenever he appears in fiction or as a toy, you're far more likely to see Bludgeon with his Pretender shell on than the inner robot inside it.
- Cool Tank: His altmode.
- Dragon Ascendant: Becomes Decepticon leader in the Marvel comics following the battle with Unicron and Scorponok's death.
- Fantastic Fighting Style: Metallikato.
- Katanas Are Just Better: He wields a katana in most fiction appearances, despite his original toy lacking such a weapon entirely.
- Ninja Samurai Skeleton Robot: Thanks to his Pretender shell.
- Proud Warrior Race Guy: After becoming Decepticon leader, Bludgeon gives a Rousing Speech to the Decepticons, saying that they're warriors and shouldn't fight what's in their oil.
- Tank Goodness: His alternate mode.
Function: Naval Warfare
- "Terror is the ultimate weapon."
- Smug Snake: Flattop thinks he's better than every other Decepticon, and often refuses to admit he needs help.
Function: Fuel Depot
- "An engine is only as powerful as the fuel that runs it."
- Con Artist: Greasepit operates a fake gas station, which he uses to siphon fuel.
- Smug Snake: The other Decepticons would like Greasepit a little more if he just stopped going on about how he's doing them a favour.
- "Anything that can sink is worth sinking."
- Mike Nelson, Destroyer of Worlds: He's no more dangerous than your average Decepticon, but, to quote TFWiki.net, get back to us on this after he shoots God in the face.
- Unwitting Instigator of Doom: In "The Primal Scream", he shoots Grimlock, the shot bounces off him and hits Primus, awakening the dormant creator with a scream... which warns Unicron about his presence, so he courses towards Cybertron. Thanks a lot, Octopunch.
- Oh, and later fiction says that this action was heard multiversally, awakening Unicron from his own dormancy.
The Pretender Monsters
Function: Aerial Attack Trooper (Birdbrain), Ground Assault (Bristleback), Demolitions (Icepick), Sonic Saboteur (Scowl), Combat Artist (Slog), Aerial Assault (Wildfly), Super Warrior (Monstructor)

- Combining Mecha: They form Monstructor.
- The Dreaded: Monstructor actually projects a field of terror, to help the pants-darkening sight of his just appearing.
- Eldritch Abomination: The Dreamwave profiles paint Monstructor as some horrific thing that just happens to come in the form of a violent robot, channelling evil there isn't a name for.
- Hair-Trigger Temper: Bristleback is filled with hate for everything and everyone.
- Hidden Depths: Underneath his mad exterior, Slog laments the loss of life the war causes on both sides. His superiors aren't happy with that.

- No Indoor Voice: Scowl, with his already loud voice amplified by his shell.
- Poisonous Person: Monstructor literally kills anything he touches.
- Small Name, Big Ego: Wildfly thinks he's some daring prankster. His fellow Decepticons think he's a moron.
- The Starscream: Icepick, in "Rythms of Darkness", thought maybe getting rid of Galvatron was a good plan. He didn't get anywhere before a large building collapsed upon him.
- Too Dumb to Live: Wildfly thought it was a good idea to bad-mouth Galvatron in earshot.
- Verbal Tic: Talks strangely, Slog does.
- Walking Wasteland: Monstructor drains the life out of everything nearby, and his solar rifle draws in every bit of sunlight nearby. He longs for the day when he just roam the galaxy killing everyone and everything he can find.
- Weaksauce Weakness: Bristleback has to stay in his shell most of the time, otherwise he'll start rusting up like mad.
Function: Ground Forces Commander
- "To show fear is to admit defeat."
- No Sympathy: Utterly contemptuous of those who show even the slightest weakness.
- Villainous Valor: Roadblock knows no fear whatsoever. He'll charge into battle alone, if he must.
Function: Aerial Defense
- "Shoot first, aim later."
- Leeroy Jenkins: Has a habit of firing upon anything that enters his airspace without checking to see who it is beforehand. He's been known to have accidentally blasted his fellow Decepticons due to this.

- Pyro Maniac: He loves seeing things blow up.
Function: Interstellar Assault
- "Terror reigns from the skies, the hapless rule on the ground."
- Ironic Name: His alternate form is a car.
- The Starscream: His Dreamwave version tried overthrowing Shockwave and luring all the larger Decepticons into a trap to be killed. And it almost worked, too.
- Weak, but Skilled: Extremely weak (even for a Micromaster), but highly intelligent and cunning.
The Sports Car Patrol
Function: Advance Assault
- "It takes force to push back the enemy, but speed clears the way."
- Ascended Extra: Blackjack's Combiner Wars toy is able to become Menasor's chestpiece, making him something of an unofficial Stunticon.
- Dumb Muscle: Hyperdrive is bad-tempered, loud and easily bored.
- The Friend No One Likes: Even the other Decepticons can't stand Hyperdrive's violence and brutality.
- Know When to Fold 'Em: Blackjack has particular skill at analysing a situation, and knowing when's a good time to strike or not. He also likes using this skill to actually know when to fold.
- Meaningful Name: Blackjack likes to gamble.
- Only Sane Man: Detour is usually the team voice of reason. If he's starting to voice objections, Blackjack takes that as a sign to get out of dodge.
- "Rule one is: There are no rules!"
- The Brute: A glorified thug.
- Dumb Muscle: Not very bright.
- Rhino Rampage: Transforms into a rhino.
- Walking Shirtless Scene: His pretender shell comes in the form of a shirtless wrestler.
Function: Aerial Espionage
- "Cover yourself with lies and no one will find you."
- Bad Boss: He seems to be this, risking his troops' lives to get the Matrix, but when he finally gets it and uses it to attack Spinister, he notices the corrupted Matrix is influencing him, since he wouldn't harm a fellow Decepticon.
- Big Bad: of the "Matrix Quest" arc.
- The Chosen Many: Thunderwing is one of the vanishingly rare Decepticons capable of reacting to the Matrix. Of course, by the time he got his mitts on it, the Matrix had... changed.
- Clothes Make the Legend: Like Bludgeon, his Pretender shell has become far more recognizable than his inner robot.
- From Nobody to Nightmare: In the IDW comics, his experiments with
Pretenderpolydermal grafting technology made him unfathomably powerful and nigh-indestructable, at the cost of obliterating his sanity and turning him into a mindless engine of destruction. The Autobot and Decepticon armies took on Thunderwing, combined and in their entirety, and even then they still couldn't kill the monster he had become.
- Impaled with Extreme Prejudice: Nightbeat used Thunderwing's brief moment of clarity to harpoon him out of the Ark.
- I Warned You: In the IDW comics he's the only scientist to figure out the Energon crisis before it was too late, and warn the others (Shockwave didn't care to tell anyone). His warnings go unheeded, and he takes matters into his own hands.
- My God, What Have I Done?: He notices he's losing it after he turns the Matrix power against Spinister.
- Person of Mass Destruction: While he wasn't the only factor contributing to Cybertron's decline, he was definitely the one to push things over the edge and leave the planet a barren, radiation-choked wasteland utterly inhospitable to Transformer life.
- Sealed Evil in a Can: By virtue of having run out of energy and being locked within his own Pretender shell. That is, until Bludgeon and his insane Pretender cult roused the beast from its slumber...
- Thrown Out the Airlock: See Impaled with Extreme Prejudice above
- Unwitting Instigator of Doom: In the IDW comics, he figured out that the planet would die out because the war would exhaust resources (and in many continuities, that's exactly what happened), so he created his polydermal technology to survive the depletion (nobody else wanted to partake in it because they thought it was disgusting). Ultimately, his mind was destroyed and he became the very thing which ravaged the planet and made it uninhabitable. His last words were screaming at his computer to cancel the procedure.
Function: Bounty Hunter
- "No prey is too large, no fee is too small."
The Battle Squad
Function: Aerial Counterattack
- "The higher they fly, the faster they'll fall!"
- Attack! Attack! Attack!: Meltdown's chosen method of attack is to rush at the enemy and try to beat them to death.
- The Creon: Power Punch is the team's greatest military asset, but he's perfectly content staying as second in command.
- Hot-Blooded: Meltdown. His Dreamwave bio states he even has the equivalent of aneurysms because of it.
- Leeroy Jenkins: Meltdown's usually approach to a fight is ignore Direct-Hit and shoot at the enemy in a frothing rage, which doesn't exactly help the team's over-all performance.
- The Paranoiac: Fireshot. His teammates know it, and laugh behind his back about it.
- The Peter Principle: Direct-Hit got to be in charge because of his skills on the battlefield, but after that it turned out he wasn't much good at actually being in charge.
- The Quiet One: Vanquish is both a master of stealth, and the non-talkative type, to the point where Fireshot actually forgets he's combined with him.
- Strategy Versus Tactics: Direct-Hit's problem. He's good at short-term tactical planning, but strategic planning is beyond him.
- Talking To Yourself: Fireshot has a habit of muttering to himself about his worries and self-important thoughts.
- Undying Loyalty: Power Punch, to Direct-Hit. This is a problem, because he refuses to realize much of the team's problems come from Direct-Hit's poor leadership, instead blaming it on everyone else.
- The Unintelligible: Half-Track gets a bit too excited about combat, causing his statements to come out garbled, much to his teammates amusement.
Function: Martial arts warrior
- "To the victor go the profits"
- Arrogant Kung-Fu Guy: Played with. He respects Bludgeon, but hopes to defeat him someday.
- Enemy Mine: Arcee finds him, Gutcruncher and Axer beaten up, and most of their unit killed, and he offers an allegiance with the remaining to hunt down their mutual enemies.
- Fantastic Fighting Style: Crystalocution. Think "Chi-blocking, but with giant robots".
- Pragmatic Villainy: Banzai-tron heavily believes in this, hoping to take people apart with his Crystalocution and sell their parts. He even disregarded the spiritual side of his training because he didn't believe in it. In the IDW verse, he has a retrieval mission, and he doesn't turn it into a Kill 'em All job because it would take too much time and resources, that and the cons they were retrieving could give them combiner tech.
Blackout and Spaceshot
Function: Ground Infantry
- "Persistence is the cornerstone of victory"
- Dirty Coward: Blackout will flee the minute he thinks the battle's going poorly. Only his fear of Spaceshot keeps him from getting out of dodge.
- Gender Flip: Their one staring role, in Beast Wars: Uprising had them as female.
- Horrible Judge of Character: Spaceshot is under the delusion that Blackout is as brave and dedicated as he is.
The Constructor Squad
Function: Battlefield Fortification
- "There's nothing like the feel of cold steel."
- Berserk Button: Mess with Excavator in Stonecruncher's presence. Do it.
- Blessed with Suck: Hammer can't move around in his own alt-mode unless he's attached to Sledge (or any other front-end micromaster).
- Boring, but Practical: Sledge values function over aesthetics and doesn't even try to combine the two. This is because he's a "soldier first, builder second" and honestly doesn't care about construction beyond what it takes to get the job done.
- The Fatalist: Grit is a strangely optimistic version of this, in that he figures that, okay, yeah, they're all going to die and everything they know and value is going to crumble to dust at some point or another because time is kind of a dick like that, but hey: He's certain that at least the Decepticon empire will continue to thrive.
- Hates Being Touched: Hammer will kill you.
- Jerk with a Heart of Gold:
- Sledge. He may seem gruff and antisocial, but if he sees his teammates struggling with anything then he's always the first to rush in to help.
- Stonecruncher. He's loud and aggressive, but he honestly means well. So long as you're a Constructor, that is.
- The Quiet One: Excavator prefers being off by himself until there's something to build, at which point he suddenly comes to life.
- The Rival: Hammer views the Constructors as being this toward the better-known Constructicons. And he's sure that his team is better.
- Sensitive Guy and Manly Man: Excavator (quiet, introverted, withdrawn until there's a project to work on) and Stonecruncher (frat boy personality, loud and aggressive)
- Sleepy Head: Knockout. To the point of narcolepsy, though it really only happens whenever he gets excited about something. Sometimes he does this while in alt-mode and poor Grit has to haul him around until he wakes up.
Function: Air-to-ground support
- "Conquest of the Autobots begins with control of the sky!"
Function: Foot soldier
- "The road to conquest is best travelled one step at a time."
- Ascended Extra: In the 2010s he was plucked from obscurity and featured as both the captain of the Scavengers in the IDW comics, as well as getting a new toy and a starring role in issue 9 of the Timelines comic.
- The Captain: Of the scavengers in the IDW comics.
- The Dragon: In the G1 comics, briefly served as Bludgeon's chief underling. Not that he did much.
- Never Smile at a Crocodile: His Titans Return figure depicts him as a... well... crocodile. Justified as his toy is a retool of Skullcruncher (under the name Skullsmasher).
- Off with His Head!: Titans Return Krok is a Titan Master.
- Only Sane Man: Of the Scavengers, he's able to think up the plans, and his personality doesn't inhibit him.
- The Paralyzer: His Titan Master given superpower lets him freeze 'bots with a glare. Then he eats them.
- Punny Name: His Action Master partner is called "Gatoraider". Krok used to be a sports star. Sports start, gatorade?
- What Measure Is a Non-Human?: Discussed with his relationship with Gatoraider. While Krok treats him as an equal, Gatoraider's sentience is barely above an animal and he behaves as such. He's not a sentient Transformer in an animalistic form (like Laserbeak or Ravage) but rather a mecha-fauna, and Krok speaking to him is more akin to someone talking to their dog rather than a fellow being.
The Military Patrol
Function: Front Line Assault
- "The ultimate force is the force of destruction."
- Barbaric Bully: Growl, who wound up joining the Decepticons after picking the wrong fight.
- Leeroy Jenkins: Tracer is always eager to be the first of the team of the battlefield, which often results in him finding himself alone and outnumbered.
- The Starscream: Dropshot, and Tracer think they'd be better at leading than Bombshock, something he knows, and welcomes. In Dropshot's case, Bombshock usually re-establishes the pecking order physically. Growl just does it to go with the flow, when he actually likes being told what to do.
- Tank Goodness: Bombshock
- Used to Be a Sweet Kid: Bombshock, long ago.
The Race Track Patrol
Function: Mobile Assault
- "There are two kinds of fighters, Decepticons and losers."
- Ascended Extra: Became the main Decepticons of the Dreamwave-era Micromaster miniseries, albeit more in a deuteragonist role rather than an antagonistic one.
- Car Fu: Barricade got his name from hid fondness from ramming.
- Drill Sergeant Nasty: Barricade acts as a nagging coach to boost his team's efficiency, but it just makes things worse because Motorhead gets distracted from battle to check if Barricade notices how well is he doing.
- Human Resources: Among Ground Hog's supplies are parts "generously donated" by Autobots.
- It's All About Me: Roller Force is obsessed with being number one.
- Loud of War: Ground Hog loves making noise.
- Mr. Fixit: Ground Hog serves as the team mechanic, helping to find ways to make the team faster (and louder).
- There Are Two Kinds of People in the World: In Barricade's mind, it's either Decepticons, or losers.
Terror-Tread and Cement-Head
- "We aim for nothing less than total victory!"
- "A gun is only as good as the one who holds it!"
- Crippling Overspecialization: He often relies on his gunslinging abilities to solve a problem, even when some other method would be more effective.
- Impaled with Extreme Prejudice: IDW comics, Revelation, his body could be seen impaled on a piece of shrapnel after Monstructor cleans his team out, he survived.
- Improbable Aiming Skills: Known as the best marksman among the Transformers.
- Killed Off for Real: He didn't survive Impactor shooting him in the chest with a Harpoon later on in The Transformers: Last Stand of the Wreckers.
Function: Self Contained Nomadic Assault Machine
- "I stand my ground... I accept any challenge... I am hungry for conflict."
- Adaptational Villainy: Noble Demon in his debut in the Japanese series, a completely Ax-Crazy, sociopathic, depraved lunatic in the IDW comics, and a regular Decepticon conqueror who won't be upstaged in the Classicsverse.
- Ambition Is Evil: Averted and Lampshaded in the IDW. Overlord has no ambitions, he doesn't seek power, and will never become The Starscream, all he wants to do is upgrade his kills from homicide to genocide. He wants to being pain and suffering and death, and getting in the way of that goal angers him.
- Authority Equals Asskicking: All versions.
- Boom, Headshot!: IDW comics, he kills Wingblazer, his partner, and Rotorstorm this way.
- Canon Foreigner: He originates from Transformers: Super-God Masterforce, a Japanese series out of continuity with the American cartoon.
- Depending on the Writer: Almost everything, including whether he's a Transformer at all! In the West, he is. In Japan, he's actually a "Godmaster," which is a human in armor emulating one. In Overlord's case, he's actually two armored humans fused together, one of which is a woman!
- Eye Scream: In The Transformers: Last Stand of the Wreckers he rips off Springer's face, blinding both eyes, and tearing one out.
- A Father And Mother To Their Men: See Unholy Matrimony, below.
- Faux Affably Evil: IDW comics, polite, eloquent, and completely crazy. Case in point, when an Elite Autobot Task Force crash down in front of him, one of them, Rotorstorm, cracks a joke. No one laughs, except Overlord, who thought it was funny. He immediately points a gun at Rotorstorm's head and splatters his companions with cranial fluid.
- Gender Bender: See above.
- The Heavy: To Big Bad Devil Z in Masterforce.
- No Export for You: He was only available in Japan and Europe.
- One-Man Army
- Psycho for Hire: Subverted in IDW Comics. He's always in it to cause suffering, but he's his own bot, and he won't be hired or working for anyone.
- Slasher Smile: Common in IDW comics like here.
- The Sociopath: IDW Comics
- Unholy Matrimony: Giga and Mega (the male and female part of Overlord, respectively). They see the Decepticons (specially the Jr Headmasters, but the way older Pretenders too) as their sons.
Function: Massive assault specialist
- "Annihilation equals victory!"
Function: Air Commandant (Skyquake), Leader (Falcon), Scientific Advisor (Skydive), Surveillance (Snare), Advance Fighter (Talon), Communications Expert (Stalker)
- Skyquake: "Break them, crush them - grind them to dust!"Falcon: "I despise weakness and spit on compassion."Skydive: "True cruelty is the highest form of art."Snare: "Fear? What's fear? It's all fun to me."Talon: "Don't get me mad... when I get mad, I get even."Stalker: "Hate till it hurts and then hate some more."
- Card-Carrying Villain: Their quotes lend the impression that they're like this.
- Six Bad Band:
- No Export for You: They were only available in Europe.
- Palette Swap: Stalker and Soundwave zig-zag with this trope. Despite being intentionally designed to look like Soundwave, he was a brand-new mold with a different altmode. Since tape decks became outdated, Soundwave has been released at least twice as a repaint of Stalker, so Soundwave is the Palette Swap, but since Soundwave is an older, more recognisable character, Stalker tends to be regarded as the Palette Swap.
- The Starscream: In the IDW comics, Calcar discusses this about Skyquake. Skyquake took over a space sector, and made it his own (Calcar calls it going native), installing his own government, and ruling the sector by himself. However, despite the power, he's still loyal to the Decepticons, and leaves his post to attack a heavily fortified Autobot Prison when Megatron orders it. Defying the trope.
Function: Operations Commander
- Your mind is mine for the taking"
- Cyborg: Just like other Gobots and unlike other Transformers, he has an organic brain in a robotic body.
- Mad Scientist
- Palette Swap: of Bumblebee, after changing his body to blend better among the Transformers
- "Mercy is not dispensed here, fools... only death!"
- An Axe to Grind
- Bad Boss: He was prone to bullying and threatening his underlings, particularly Shrapnel. At one point, one of his troops was killed by a malfunctioning spacebridge. Rather than caring much, Straxus just send another guy in to see what had happened. They died too.
- Black Eyes of Evil: His eyes are completely dark in the original comics. Most other depicitions tend to ignore this, but Japanese media and toys are pretty consistent on it.
- The Caligula: Even by Decepticon standards. Which is really saying something.
- Combining Mecha: Appeared in the Japanese exclusive United EX storyline as one.
- Grand Theft Me: With a copy of Megatron's body in the Marvel UK comics. Sort of. It's complicated.
- Losing Your Head: In the Marvel UK continuity, his encounter with the Space Bridge has him reduced to just a head.
- The Starscream: Often found trying to overthrow Megatron, or brainwash him into being a puppet.
- Toyless Toyline Character: During the original toyline run. He got a figure in 2010 as part of the Generations toyline.
Function: Aerospace warrior
- "Unchecked power is the true path to divinity."
- Ascended Extra: He first appeared as an unnamed background character in the first animated episode.
- A God Am I: His lethal radioactivity has caused him to believe that he is a god. In fact, his Masterpiece toy comes with a redeco of Starscream's crown, cape and shoulder pads (though this may or may not be a coincidence).
- Palette Swap: Just like most Seekers, he's one for Starscream.
- Walking Wasteland: Sunstorm is so named because he is dangerously radioactive; his mere presence causes other Transformers to melt, corrode and die. This, combined with his physically and mentally unstable nature, has resulted in Sunstorm developing a massive god complex.
- Ascended Extra: Like Sunstorm, he was a generic Seeker that appeared in the first episode.
- Palette Swap: Of Starscream, though he more accurately resembles Thundercracker with extra bits of red and white.
- Ascended Extra: Appeared as a no-name generic in the first episode, alongside Bitstream and Sunstorm, attacking Wheeljack and Bumblebee.
- The Engineer
- Palette Swap: He's a purple Starscream.
- Playing with Fire: His favorite creation is his pyropathic flamethrower.
Acid StormA member of the Rainmaker squad.
- Ascended Extra: Not to the extent of Sunstorm, but Acid Storm has had more appearences since his one episode.
- Cool Plane: Transformed into a pyramid-jet in his brief one episode appearance. IDW and toys would give him the standard F-15 Eagle mode.
- Meaningful Name: He makes acid rain along with his fellow Rainmakers (though their since-elaborated-on powers seem to imply making acid rain is something only he can do).
- Mythology Gag: His quiet nature and preference to wallow in anonymity is likely a reference to his appearance in "Divide and Conquer", where he was a generic Seeker who didn't speak.
- Nice Job Fixing It, Villain!: When Shrapnel blows Ultra-Magnus's ship out of the sky, Acid Storm yells at him as his rash actions have now sent debris heading towards their outpost. It gets destroyed.
- Palette Swap: Like all Seekers, he's a Starscream recolor. His design did change from his initial bright green color to a more appealing jungle camouflage paint job.
- The Quiet One: He rarely speaks and prefers to silently serve under his superiors.
- Shut Up, Kirk!: Gives one to Starscream when he tries to give a speech about letting go of the Decepticon cause for peace.
Nova StormAnother Rainmaker member.
- Ascended Extra: Like the rest of his squad, Nova Storm was originally a generic Seeker painted in bright yellow (though he wasn't Sunstorm).
- Cool Plane: Turns into a Cybertronian tetrajet in his one appearance.
- Divergent Character Evolution: In the same "Ask Vector Prime" update that gave him his name, he got a snazzy new look◊.
- Meaningful Name: Nova Storm is able to survive volcanic or otherwise extremely hot environments for small periods of time.
- Palette Swap: He's a Seeker, so of course.
- Playing with Fire: Downplayed; his armor allows him to survive volcanic environments.
Ion StormThe third and final Rainmaker member.
- Ascended Extra: Yet another background Seeker from the cartoon.
- Cool Plane: Like the other Rainmakers, he turned into a Cybertronian jet in his one appearance in "Divide and Conquer".
- Divergent Character Evolution: Like with Nova Storm, he was redesigned◊ in the same "Ask Vector Prime" update that named him.
- Meaningful Name: Ion Storm has control over electricity.
- Palette Swap: Like any other Seeker.
- Shock and Awe: Ion Storm is electrokinetic, and can create EMPs.
- Adaptational Badass: Went from a weepy sister in her debut to a full fledged, though still kinda depressed, Decepticon Warrior in the Transformers: Wings of Honor comic.
- Calling Your Attacks: Guess it runs in the family.
- Dude, Where's My Respect?: Wings of Honor Comic mentions that she isn't taken very seriously, reduced to a servant by Deathsaurus and talked down to by Starscream.
- Glass Cannon: Takes on Magnum and cuts him down, but before she can kill him, she's beaten by a single punch.
- Shrinking Violet: Manga and Wings of Honor. In the Wings verse her bio does mention her isolation, but this trope causes many to underestimate her.
- Undying Loyalty: To Deathsaurus.
TurmoilDecepticon soldier and former commander of Deadlock (aka Drift).
- Arm Cannon
- Bad Boss: Kills the aliens he used to build his ship, not very pleasant to the Decepticons under him either.

FulcrumA Decepticon soldier in The Transformers: More Than Meets the Eye.

- Heroic Sacrifice: As a living Bomb he attempts to do this to the DJD to save his new friends. He turns out to be a dud, and the DJD leave because they think he's dead. He survived, and it's revealed that Spinister cut out his explody part so he wouldn't blow up when they were trying to salvage him.
LockdownA Decepticon bounty hunter. First appeared in IDW's Drift miniseries, now leader of a band of Decepticons in The Transformers: More Than Meets the Eye.
- Bounty Hunter: Like his namesake.
- Canon Immigrant: An interesting case. The character himself comes from Transformers Animated, while his design is based on the Lockdown figure from a Revenge of the Fallen movie toyline.
- Cool Car: Transforms into a muscle car.
- Hook Hand: Has a large hook in place of his right hand.
LugnutA massive Decepticon bruiser that blindly follows Megatron. Currently a member of Lockdown's group in The Transformers: More Than Meets the Eye.
- The Brute
- Canon Immigrant: This one's from Transformers Animated. His second appearance has him in a direct reference, while his first had him based of his Reveal the Shield Toy.
- Cool Plane: His toy transforms into a bomber plane.
- Rocket Punch: The Punch of Kill Everything.
- Sycophantic Servant
- Undying Loyalty: Carried over from his Animated namesake. If the grand and GLORIOUS Megatron commands it, Lugnut will obey without question.
Decepticon Justice DivisionWhen Decepticons disobey orders or go rogue, It's the DJD's job to hunt them down. Debut in The Transformers: More Than Meets the Eye.
- Torture Technician: a whole team dedicated to it.
TarnWell spoken member of the DJD, turns into a tank.
- Arm Cannon/BFG: He has two Fusion cannons on his arm, showing his loyalty to the cause.
- Big Bad
- Captain Patriotic: Inverted. Tarn is loyal to Megatron above all others, and his ideals about how Cybertron should be run. Tarn has the Decepticon Symbol grafted to his face.
- Fantastic Drug: Addicted to transforming, if one looks at his scenes in issue 8, he transforms a lot.
- Faux Affably Evil: Talks politely, quotes poetry and philosophy, all as you die. His actual words go at a frequency so that the spark of the victim gives out
- Torture Technician
- Wicked Cultured
KaonTurns into an Electric chair and organizes the list of people the DJD hunt down, he owns the Pet.
- Black Eyes of Evil: His optics are black and gives the appearance that he has only eye-sockets. While not intentional, James Roberts admits to liking the idea Kaon's blind.
- Electric Torture: Employed via his chair.
- Psycho Electro: He shoots electricity from his chair mode and his hands for combat.
- Torture Technician: Via Electric Torture
- Eye Scream: Inverted. He's got all sorts of spikes and drills under his face, and they're all over, except his eyes, as he needs to see, and presumably the victim can still see when his face get's put over them.
- Nightmare Face: Behind his face is a number of torture utensils, and he puts his face over victims.
- Torture Technician
- The Unintelligible
- Multi-Armed and Dangerous: He has two extra crane like arms.

The PetKaon's pet Sparkeater/Turbofox.
NickelThe DJD's resident physician.

- The Medic: To the DJD
- The Smurfette Principle: The only female Decepticon seen in the IDW series.

- Villainous Friendship: Has this with the DJD.
Function: LeaderCreated out of spare parts from Megatron's construction, Megaempress (メガエンプレス Megaenpuresu) leads the Female Decepticons as the self-proclaimed "Empress of Destructicon". She has a special team of vassals, the 4 Guards, to serve as her ever-present bodyguards. She's still a force to be reckoned with, though, as her power is comparable to Megatron's own and she can use her rail fusion cannon and Judge Pickel weapons to wreak destruction across the land. She has the "special ability" to seduce any male Transformer to do her bidding.
- Arm Cannon: Averted. The ladder for her vehicle form acts a weapon of her choice, however.
- Big Bad: She and the 4 guards were this for the Megatronia chapter but were replace with Baldigus and later Unicron.
- Distaff Counterpart: Of Megatron, only she doesn't transform into a gun.
- Evil Cannot Comprehend Good: Tries to use her power to make Optimus Prime her slave, but is shocked when he used her Judge Pickel to pierce himself to break her control as he states Elita One's name.
- Evil Overlord: leads the Female Decepticons as the self-proclaimed "Empress of Destructicon". You do the math.
- Greater-Scope Villain: Tries to take over the entire decepticon faction
- Large Ham
- Powerful Pick: Her Judge Pickel is this.
- Sealed Evil in a Can: Shockwave put her and Flowspade in stasis after her failed coup. She would be freed millennia later in 2021 when her remaining followers realized the devastation of Cybertron broke the seal and rushed Shockwave's facility to wake their empress.
- Villainous Friendship: Seems to have one with Flowspade.
MegaplexMegatron's body-double, a clone made in his image who often leads battles in Megatron's stead
- Actually a Doombot: His purpose. And since Megatron didn't trust a duplicate of himself, Megaplex is nowhere near as dangerous as Megatron, meaning it's easy to spot that he's a fake quickish.
- Kill It with Ice: Megaplex's preferred artillery is freeze shells.
- Palette Swap: His Collectors Edition toy is just Megatron's toy with the original Japenese release colouration.
