While both PeterCullen and Creator/FrankWelker have portrayed Optimus Prime and Megatron in other productions including video games, this is the first time the two of them have been able to work together portraying their iconic characters in a television series since ''WesternAnimation/TheTransformers''. Both have stated how delighted they were to work together again and how fond they were of each other.

* ActorAllusion:
** Ratchet becomes a manic MadScientist over the kids' science fair projects. It's as funny as it sounds, particularly when Jack's machine starts spasming like a severed limb.
*** Later on, he tests synthetic energon on himself that leaves him with unexpected results.
*** Oh, and the synthetic energon looks suspiciously like [[Film/ReAnimator another glowing, green liquid]] that Creator/JeffreyCombs has worked with in the past.
*** And in "Scattered", he hides out in [[WesternAnimation/JusticeLeague everyone's trash]].
** [[spoiler: Creator/WillFriedle plays [[WesternAnimation/BatmanTheBraveAndTheBold a young, brash, brightly-colored hero with an insect theme]]. [[WesternAnimation/BatmanBeyond He also inherits his role (as leader) from an older hero who trained him]]. He's even colored mostly black when it happens.]]
** This wouldn't be the first time Creator/NolanNorth's voiced [[WesternAnimation/YoungJustice a young hero who idolizes an older, red and blue-clad hero]].
** Ultra Magnus is voiced by MichaelIronside. [[spoiler:[[{{Fingore}} Yeah, he's not going to keep that hand.]]]]
** Creator/ClancyBrown plays the human super villain Silas, who bedevils Optimus Prime. By coincidence or design, this is the second time Clancy has found himself playing a supervillain who is an antagonist to a [[WesternAnimation/SupermanTheAnimatedSeries benevolent super-powered alien primarily clad in the colors red and blue]].
** In the Japanese version, Arcee and Jack are played by Creator/ShizukaIto and Creator/JunFukuyama respectively. They reprise their roles from the RomanticComedy HaremAnime ''VisualNovel/ToHeart2'' in that they once again play a couple with a Big-Sister and Little-Brother relationship.
** Similarly, SteveBlum in the original version once again plays Shin from ''Manga/FistOfTheNorthStar'', in that Starscream is a sadistic warlord who takes pleasure in shoving his hand through the rib-cages of helpless prisoners.
** Cliffjumper's vehicle mode has bull's horns on the front of the hood. One of the nicknames his original voice actor, Wrestling/DwayneJohnson, has when performing as The Rock is "the Brahma Bull".
* BreakthroughHit: Stands with ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' as one of the shows responsible for Creator/TheHub's success.
* DawsonCasting: Andy Pessoa is a teenage actor playing 12-year-old Raf, though they are already running into problems with keeping his childlike voice and his voice has clearly deepened as of the season 2 premiere.
* FanNickname:
** Screamernaut and Iron Screamer after Starscream [[spoiler:gets the Apex Armor and becomes a nigh-unstoppable war machine]].
** Silasdown for [[spoiler:Silas' fusion with Breakdown's corpse]].
** Yanderachnid for Japanese!Airachnid.
** "Galvatron" for [[spoiler:Megatron after Unicron brings him BackFromTheDead and then [[DemonicPossession takes over his body]], [[BodyHorror radically altering it]]]]. Contrary to fan expectations, the name was never actually used in the show.
* FiveEpisodePilot: This is actually the first ''Transformers'' series to begin with a ''[[ExactWords five]]''-parter:
** The [[WesternAnimation/TheTransformers original series]] began with a three-parter, and only ever had one five-parter, which opened up the third season.
*** Had the series not been cancelled, "The Rebirth" would have been a five-parter.
*** Unless you're Japanese, in which case ''[[WesternAnimation/TheTransformers Transformers 2010]]'' (the Japanese dub of Season 3) ''technically'' started with the 5-part "Five Faces of Darkness"...
** ''WesternAnimation/BeastWars'' started with a two-parter, while its sequel ''WesternAnimation/BeastMachines'' averted this altogether.
** Avoided with all of the {{anime}} series (it's a Western thing, after all).
** ''WesternAnimation/TransformersAnimated'' also only began with a three-parter.
* HeyItsThatSound:
** Both Skyquake's stasis pod and the Energon Harvester activate with the sound of [[Series/StargateSG1 Stargate's]] zat gun - as do the stun beams fired by the ''Nemesis''.
** Airachnid's web-shooters make the same sound that SpiderMan's do in ''WesternAnimation/TheSpectacularSpiderMan''.
** At least three sounds seem to have been lifted directly from WesternAnimation/RoughnecksStarshipTroopersChronicles: the alarm in the Autobots' base is the same as that on the Valley Forge, Starscream's missiles swoosh like Javelin missiles and when Ratchet's medical probe is brought to unlife by Dark Energon it screams like a warrior Bug.
* HeyItsThatVoice:
** Of course, we must start with Creator/PeterCullen and Creator/FrankWelker reprising their roles as Optimus Prime and Megatron. [[spoiler: Frank Welker also reprises the role of Soundwave.]]
*** [[spoiler: It should be noted that Welker uses the same voices for Soundwave as he did for ''both'' G1 and the Live Action films. (The only actual difference between the two is that the G1 version uses electrical modulation). In ''Prime'', it's actually a simultaneous broadcast of both the modulated and un-modulated versions.]]
** Wrestling/DwayneJohnson was Cliffjumper in the pilot.
** Creator/SumaleeMontano is Arcee.
** Creator/KevinMichaelRichardson is Bulkhead, Makeshift, and [[spoiler:The ''Nemesis''[=/=]Trypticon]]. For Bulkhead he seems to be using his [[VideoGame/KnightsOfTheOldRepublic Jolee Bindo]] voice.
** Creator/JeffreyCombs is Ratchet.
** Creator/JoshKeaton is Jack Darby.
*** And [[Series/NightCourt Markie Post]] is his mom.
** Creator/SteveBlum is [[TheStarscream Starscream]], who seems to be channeling [[WesternAnimation/TheSpectacularSpiderman the Green Goblin]] and [[Manga/{{Naruto}} Orochimaru]]. He's also Darksteel.
** Creator/DaranNorris is Knock Out.
*** And he's not the first [[Anime/DigimonFrontier intelligent, metallic villain]] he's played.
*** Hey, [[WesternAnimation/TheFairlyOddParents Timmy's dad]] has always been obsessed with a red sports car.
*** He was also [[WesternAnimation/TheSpectacularSpiderMan J. Jonah Jameson]].
** Creator/AdamBaldwin is Breakdown.
*** Funnily enough, Creator/GinaTorres is Airachnid.
** [[Film/{{Ghostbusters}} Ernie Hudson]] is Agent Fowler.
** Creator/ClancyBrown is Silas. [[Franchise/{{DCAU}} Not the first time]] he's played a [[SelfDemonstrating/LexLuthor tech-obsessed villain]].
** Richard Green (known to some as [[VideoGame/XMenLegends Mag]][[VideoGame/MarvelUltimateAlliance neto]] or [[WesternAnimation/TheBatman Hugo Strange]]) is Skyquake.
** James Horan ([[Series/StarTrekDeepSpaceNine Ikat'ika]]) is Wheeljack.
** Creator/JohnNoble is Unicron.
** Bit easier to miss, but Reggie Bannister is the security guard from episode 10.
** Creator/TonyTodd, who most Transformers fans know as [[Film/TransformersRevengeOfTheFallen The Fallen]], is Dreadwing.
*** In [[LicensedGame the game]], FredTatasciore fills in for him.
** Robert Forster, also known as [[Series/{{Heroes}} Arthur Petrelli]], is General Bryce.
** Creator/JohnDiMaggio is the ConspiracyTheorist Vogel from "Tunnel Vision".
** Creator/DavidKaye is Hardshell. He sounds like a more guttural and vicious WesternAnimation/BeastWars Megatron.
*** Or perhaps like ''WesternAnimation/TransformersAnimated'' Lugnut without the metallic effect.
** Creator/DavidSobolov is Shockwave.
** Billy Brown ([[Series/{{Dexter}} Mike Anderson]]) is Cliffjumper in "Out Of The Past".
** Creator/NolanNorth is Smokescreen. He's also Skylynx.
** Creator/GeorgeTakei is Alpha Trion. It's not the first time he's voiced a [[WesternAnimation/TransformersAnimated mentor Autobot]], either.
** Creator/RobinAtkinDownes is Thunderwing in [[LicensedGame the game]].
** Creator/MichaelIronside is Ultra Magnus.
** Creator/PeterMensah is Predaking.
** [[spoiler: Creator/WillFriedle is Bumblebee]].
** The Hungarian dub brought back from the [[Film/{{Transformers}} movies]] the voices of: Optimus Prime, Megatron, Starscream, surprisingly Arcee (and it works!), and even more surprisingly Agent Simmons... as Agent Fowler. Besides these...
*** Megatron is also [[Anime/TransformersCybertron Leobreaker]] and [[TheClevelandShow Cleveland's dad]].
*** Starscream slips over into [[Film/TheLordOfTheRings Gollum]] very often.
*** Arcee's also [[Manga/{{Naruto}} Tsunade]].
*** Yes, Fowler is Winston from {{Ghostbusters}}... [[WesternAnimation/TheRealGhostbusters the animated version]]. He's also WesternAnimation/{{Superman|TheAnimatedSeries}}.
*** Skyquake is, in turn, Brainiac. As well as [[WesternAnimation/SpongebobSquarepants Patrick Star]] and TheTick.
*** Bulkhead is [[WesternAnimation/BatmanTheAnimatedSeries Bat]][[JusticeLeague man]] attempting to do a deeper voice.
*** Jack is [[WesternAnimation/TheFairlyOddparents Nickelodeon!Timmy Turner]] in seasons 1 & 2, and [[WesternAnimation/AdventureTime Finn]] in season 3.
*** June is [[Disney/BeautyAndTheBeast Belle]].
*** Cliffjumper is [[WesternAnimation/{{Futurama}} Fry]] and [[WesternAnimation/SouthPark Randy Marsh]].
**** And so is [[spoiler:Bumblebee]].
*** Ratchet is [[WesternAnimation/{{Futurama}} Zapp Brannigan]], [[TheClevelandShow Cleveland Junior]] and [[LazyTown Sportacus]]. Halfway through season 3, he becomes [[Manga/DeathNote L]].
*** Knock Out is [[MyNameIsEarl Earl]].
*** Wheeljack is {{Fanboy|AndChumChum}}.
*** Breakdown has the voice of [[{{Trigun}} Vash the Stampede]].
*** Silas is often typecast as a deep-voiced badass hero or villain, invariably using the same voice. Notable recent roles include [[WesternAnimation/BatmanTheBraveAndTheBold Aquaman]] and [[Manga/{{Naruto}} Jiraiya]], as well as Optimus Prime in some TV ads and promos.
*** Airachnid for the first two seasons is both [[WesternAnimation/DextersLaboratory Dexter's mom]][[note]] Second voice.[[/note]] and [[WesternAnimation/KimPossible Mrs. Possible]].
*** Tailgate is [[TotalDramaIsland Trent]].
*** Smokescreen is [[WesternAnimation/FamilyGuy Chris Griffin]], also [[Manga/SoulEater Death the Kid]], [[Anime/FullmetalAlchemist Jean Havoc]], [[WesternAnimation/HowToTrainYourDragon Hiccup]], and ''tons'' of others.
*** Hardshell is definitely [[Franchise/ScoobyDoo Shaggy]] trying to sound menacing.
*** Ultra Magnus is [[WesternAnimation/GreenLanternTheAnimatedSeries Kilowog]] and 2nd [[WesternAnimation/KingOfTheHill Buck Strickland]]
*** Predaking is [[Series/{{Friends}} Ross]]. More recently, also [[WesternAnimation/StarWarsTheCloneWars Darth Maul]]'s 2nd voice.
** The Japanese dub is also a veritable who's-who of talent:
*** [[Creator/ToshiyukiMorikawa Optimus Prime]] is [[Anime/TekkamanBlade D-Boy]] and [[VideoGame/FinalFantasyVII Sephiroth]].
*** [[Creator/KeijiFujiwara Megatron]] is, fittingly enough, [[Anime/MobileSuitGundam00 Ali-Al Sanchez]].
*** [[Creator/NobuoTobita Ratchet]] is [[Anime/MobileSuitZetaGundam Kamille Bidan]].
*** [[Creator/ShizukaIto Arcee]] is [[Anime/TengenToppaGurrenLagann Boota, Darry]], and Japanese![[StarWarsTheCloneWars Ahsoka Tano]].
*** Starscream is [[FateZero Caster]].
*** [[Creator/NoriakiSugiyama Cliffjumper]] is [[Manga/{{Naruto}} Sasuke]] and [[VisualNovel/FateStayNight Shirou Emiya]].
*** [[Creator/JunFukuyama Jack]] is [[Anime/CodeGeass Lelouch Lamperouge]].
*** [[Creator/MotokoKumai Raf]] is [[Manga/CardcaptorSakura Li Syaoran]] and [[WesternAnimation/MyLittlePonyFriendshipIsMagic Spike]].
*** [[Creator/KenjiNomura Fowler]] is [[Manga/{{Bleach}} Yammy]] and Japanese![[VideoGame/RatchetAndClank Captain Quark]].
*** [[Creator/HitomiNabatame June]] is [[LightNovel/OreNoImoutoGaKonnaNiKawaiiWakeGaNai Saori Bajeena]].
*** Miko... is the only one who doesn't have a recognizable seiyuu, as she's voiced by newcomer Nozomi Furuki.
*** [[Creator/YasunoriMasutani Knock Out]] is [[SoulCalibur Raphael Sorel]].
*** Breakdown is [[Manga/{{Basilisk}} Jimushi Jyubei]].
*** [[Creator/RyokaYuzuki Airachnid]] is [[Manga/{{Naruto}} Ino Yamanaka]].
*** [[Creator/KentaMiyake Shockwave]] is [[Manga/WolfsRain Tsume]].
*** [[MasamiIwasaki Skyquake and Dreadwing]] are [[AxisPowersHetalia Norway]] and [[GunslingerGirl Alfonso]].
*** Wheeljack is [[{{Beyblade}} Yamashita Cane]].
*** [[Creator/UnshoIshizuka Silas]] is [[Anime/CowboyBebop Jet Black]] and Japanese![[Series/CSIMiami Horatio Cane]].
*** Unicron is [[Anime/MobileSuitVictoryGundam Tassilo Vago]].
*** The Vehicons are [[Anime/BattleBDaman Grey Michael Vincent]] and [[GhostHunt Kazuya Shibuya]].

*** [[Creator/TakahiroSakurai Vince]] is [[Manga/{{Naruto}} Sasori]] and [[VideoGame/FinalFantasyVII Cloud Strife]].
*** [[TakashiNagasako Bulkhead]] is Franchise/DonkeyKong.
*** [[Creator/{{Chafurin}} General Bryce]] is [[Manga/OnePiece Saint Charloss]].
*** [[Creator/TetsuInada Vogel]] is [[DragonBallKai Nappa]] and [[MegaManZero Hidden Phantom]].
*** [[Creator/MitsuoIwata Hardshell]] is [[Manga/{{Akira}} Shotaro Kaneda]].
*** [[Creator/KazuyukiOkitsu Smokescreen]] is [[Anime/SacredSeven Kaneda]].
** Jack is [[InvaderZim Zim]] in Spain.
** Arabic dub:
*** Arcee is [[WesternAnimation/HouseOfMouse one of Donald's nephews.]] (at last judging by the Arabic wiki).
*** Miko is [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rainbow Dash]].
** In Italy, Airachnid is [[WesternAnimation/MyLittlePonyFriendshipIsMagic Zecora and Queen Chrysalis]].
** In Finland
*** Interestingly enough, Arcee (Susa Saukko) is [[WesternAnimation/TheAdventuresOfChuckAndFriends Chuck]] and [[WesternAnimation/MyLittlePonyFriendshipIsMagic Fluttershy]].
*** Airachnid (Ella Pyhältö, née Keranto) is [[WesternAnimation/MyLittlePonyFriendshipIsMagic Zecora and Season1!Nightmare Moon/Princess Luna]].
* IKnewIt: Many had guessed [[spoiler: Unicron was either Earth, or somehow connected to it]], due to the fact [[spoiler: Dark Energon ''erupted from a volcano'']].
** Given both ''Prime'' and ''TransformersWarForCybertron'' are set in the Franchise/TransformersAlignedUniverse, [[spoiler: Ratchet's recap of ''[=WfC=]'' confirms that the being credited as "Core" in the game is indeed Primus.]]
* LyingCreator: [[spoiler: Originally, it was stated Ironhide was going to be on the show, but so similar to ''[[WesternAnimation/TransformersAnimated Animated]]'' Bulkhead that they just opted to do Bulkhead instead. However, so the Season 1 set, the reason given was because of Ironhide's death in ''[[Film/TransformersDarkOfTheMoon Dark of the Moon]]'', hinting the reason given earlier was a lie to prevent spoilers.]]
* MythologyGag: [[TransformersTheMovie One Shall Stand]], [[Film/{{Transformers}} One Shall Fall.]]
** '''G1:'''
*** The abandoned missile silo the Autobots use for home base has a passing resemblance to Mount St. Hilary, the resting place of the Ark in [[TransformersGeneration1 G1]]. Right before trying to blow up the space bridge, Ratchet says it's time to "[[TransformersTheMovie light our darkest hour!]]" The design of the Decepticon ship hearkens back to the unnamed Decepticon ship from G1, given the name ''Nemesis'' in ''WesternAnimation/BeastWars''.
*** Optimus Prime and Megatron are both voiced by the same actors (PeterCullen and Creator/FrankWelker) who first voiced them in G1. [[spoiler: In "Minus One", Welker also reprises the role of Soundwave.]]
**** Whenever Soundwave plays back audio, a subtle but distinct audio modulation is applied, the same used for G1's Soundwave.
*** The naming of the episode "Convoy" is quite deliberate, as ''Commander Convoy'' is the name of Optimus Prime in Japan.
**** Also, Prime's trailer in said-episode is a perfect replica of G1 Prime's trailer.
*** In "Sick Mind", Megatron muses over Optimus Prime's deteriorating health and makes a comment on him "fading to Gunmetal gray" (i.e. losing his coloration upon the moment of death)... the same thing that happened when he died in ''TransformersTheMovie'', and in many other series, the one sign that a Transformer's spark has been extinguished and they are [[KilledOffForReal truly dead]].
*** In "Shadowzone", while Starscream is being repaired by Knock Out, the latter suggests Starscream take the opportunity to upgrade his somewhat obsolete tech and missing arm with a [[TransformersGenerationOne null-ray.]]
*** In "Partners", Starscream tells Airachnid how (prior to joining the Decepticons) he was Air Commander of a squadron of Energon Seekers. In [[TransformersGenerationOne Generation 1]], Starscream's title in the Decepticons was Air Commander, and all jet-model 'Cons were called Seekers.
*** In the same episode, Bulkhead mentions the Transformers [[TheAntiChrist Antichrist]] / {{Satan}} figure The Fallen.
*** In "T.M.I.", Bulkhead also name-drops Perceptor, a G1 Autobot scientist, while doing Cybertronian math.
*** In "One Shall Fall", Megatron attacks Bumblebee, critically injuring his passenger. G1 Megatron did the same thing in the second-season opener, "Autobot Spike."
*** In "One Shall Rise, Part 1" Megatron [[spoiler: presents himself to Unicron at the maw of the volcano as his "Herald", a term used before, mostly in the comics, to describe any Transformer that directly serves Unicron.]]
*** Ratchet's Kung Fu from "Stronger, Faster" is a nod to the G1 episode "Changing Gears" when [[http://tfwiki.net/w2/images2/thumb/b/b9/G1_ChangingGears_Ratchet_karate.jpg/250px-G1_ChangingGears_Ratchet_karate.jpg Ratchet totally Bruce Lee-kicked Thundercracker]].
*** The title is a homage to the Action Masters toys, whose commercial mentions the Transformers becoming "Stronger, faster, more alive." In the MarvelComics series, the Action Masters were created through the use of Nucleon - a substitute for Energon that could do very bad things (such as ruining their transformation ability, as the Action Masters were non-transforming figures) to the user. (In "Stronger, Faster," the plot is about Ratchet's synthetic Energon proving to be PsychoSerum.)
*** Also from "Stronger, Faster", Knock Out's taunting of Ratchet regarding the Synthetic Energon ("What are you going to do, drink it?") is a nod to the G1 episode "Microbots", where the Decepticons drank copious amounts of Energon, becoming drunk in the process.
*** In "One Shall Rise, Part 1", Miko mistaking [[spoiler:"Unicron" for "Unicorn" is a reference to the infamous Malaysian dub of ''TransformersHeadmasters'', where at one point Galvatron declares "THIS IS UNICORN!" in reference to his "Grand Galvatron" plan.]]
*** Also in "One Shall Rise, Part 1", Optimus sums up the Primus/Unicron legend (first introduced in the G1 comics), including the Thirteen Primes.
*** In "One Shall Rise, Part 3," it's revealed that [[spoiler:the key that Jack received from Optimus wasn't for the ground bridge power supply, but Vector Sigma, the mega-computer that gives sentience to non-sentient objects.]]
*** In "Masters & Students," Starscream declares himself the "[[http://tfwiki.net/wiki/Emperor_of_Destruction Emperor of Destruction]]" while taking command of the Decepticons, a term that, while rarely brought up in American ''Transformers'' series, has often been used by Japanese fiction to refer to 'con leaders.
*** In "One Shall Rise, Part 3", Optimus says the Matrix will [[TransformersTheMovie "light our darkest hour!"]]
*** [[spoiler:When Unicron posesses Megatron for the last time, he becomes engulfed in purple flames. Now, we already know that he directly took his name from Megatronus Prime, one of the original thirteen, who later became The Fallen. In various media, The Fallen is always coated in a fiery aura.]]
**** [[spoiler:Also whenever Unicron tries to possess Megatron, the lighting and sound effects were exactly like those in TransformersTheMovie, right down to Megatron clutching his head and falling to his knees in pain.]]
*** In "Operation Bumblebee, Part 1", Bumblebee gets his Transformation Cog stolen by MECH and is left unable to transform. The same thing happened to Trypticon in the G1 cartoon. It even looks sort of the same.
*** Ratchet also reiterates to Bumblebee why he has to stay at the base while the rest of the team searches for his T-Cog. They're "Robots In Disguise", after all.
*** Megatron tries to use [[spoiler:the Forge of Solus Prime]] to create what Knock Out calls a "Fortress Maximus-grade Nucleon Shock Cannon", and fails in "Operation Bumblebee, Part 2".
*** In "Loose Cannons" Wheeljack mentions former Wreckers Impactor, Roadbuster, Rotorstorm, Pyro and Seaspray [[spoiler:as fallen comrades. In even more of a mythology reference, every single one of the Wreckers named, except for Seaspray, who's a new addition, have actually served as Wreckers in various G1 continuities and have also died in those appearances. Impactor didn't survive his initial appearance in the Marvel comics, and neither did Roadbuster (who also died in the Dreamwave comics) and both Rotorstorm and Pyro were killed in ''Last Stand of the Wreckers''.]]
*** In "Nemesis Prime" Agent Fowler was playing an instrumental version of ''The Touch'' on his radio.
**** Nemesis Prime, in all continuities he appears, is the evil clone of Optimus Prime.
*** In "Triangulation" the Apex Armor is from the comics where Sentinel Prime used one to fight Megatron and was defeated.
*** "Toxicity" introduces a high-ranking Insecticon named Hardshell. Hardshell was an alternate name of Bombshell, a prominent Insecticon character in G1.
*** Smokescreen's alt-mode is a race car with the number 38 on the side. It even uses the same colors: red, white and blue, just in a different scheme.
*** In "The Human Factor", [[spoiler:a human is placed in a robot's body in order to preserve him.]] Something similar happened in the episode "Autobot Spike".
*** New Kaon seems identical to Castle Decepticon and Fortress Sinister from [[Comicbook/TheTransformers Marvel Comics]].
*** While it's ''Transformers'' tradition to re-use character names from previous series (to serve as both an homage and to preserve the trademark to the name), the leader of the Predacons is named Predaking. In G1, Predaking was the name of the combined form of the Predacons, which were merely a combiner group then. (Doubly notable as this is the first use of the name "Predaking" since 1986.)
*** While complementing Bumblebee's new "stealth" paintjob, Arcee dryly notes that if she inverted ''her'' colors she'd be pink. Pretty much every other version of Arcee ever has been some shade of pink.
*** When Wheeljack wants to take out Darkmount [[MadBomber Wrecker-style]], [[ByTheBookCop Ultra Magnus]] states that he couldn't deal with Wrecker-style before and he won't deal with them now, referencing the [[MemeticMutation infamous line of Ultra Magnus]] [[NeverLiveItDown when Hot Rod and Kup are under attacked by Decepticons]] in [[WesternAnimation/TransformersTheMovie the 1986 movie]].
*** [[spoiler:Soundwave's first line, "Soundwave superior. Autobots inferior." is a CallBack to his line to the Constructicons during ''[[WesternAnimation/TransformersTheMovie The Movie]]'', which like the Ultra Magnus line, had become [[MemeticMutation popular amongst the fanbase]].]]
** '''WesternAnimation/BeastWars:'''
*** Energon takes the form of bluish crystals, and artificially seeded on a planet where they grow.
*** In ''Sick Mind'' Bumblebee enters Megatron's mind for information, and then Megatron ends up in Bumblebee's mind. The same thing happened between Blackarachnia and Tarantulas.
*** In "One Shall Fall" Optimus Prime mentions "The Covenant of Primus" AKA the [[HollywoodApocrypha Transformers Bible]] introduced at the end of WesternAnimation/BeastWars.
*** The battle between Optimus and Megatron in "One Shall Fall" is very similar to the final episode of ''WesternAnimation/BeastWars''. Mountainous terrain, lighting storms, both combatants quoting the Covenant of Primus, [[spoiler:and Optimus loses.]]
*** In "One Shall Rise" Megatron ends a gloating sentence with [[VerbalTic YEEESSS!]]
*** Ratchet, while in the process of waking up from stasis (essentially Transformer morphine), mentions Fuzors, a type of Transformer from ''Beast Wars'' that possessed a beast mode that was a combination of two different animals, and even mentions one by name, Bantor, and also that part of his animal mode was a tiger (and part mandrill) in "Operation Bumblebee, Part 2".
*** In "Triage", Wheeljack's ship managing to shoot down Laserbeak only to be shot down in return is very reminiscent of the battle between the ''Darksyde'' and ''Axalon'' that trapped both the Maximals and Predacons on Prehistoric Earth in the first episode of ''Beast Wars''.
*** In "Toxicity", Hardshell is knocked into a volcano, but manages to climb out and attack Bulkhead again. This isn't the first time a Decepticon voiced by DavidKaye has ended up rising out of a volcano to attack the person who dunked him in it.
*** The crash landing of the Nemesis on a cliff edge in "Armada" is way too similar to that of the Axalon.
*** When Optimus wants the Autobots to really burn rubber in vehicle mode, he'll order them to shift to "Maximum Overdrive" (even if he's the only one doing it). It seems to be Prime's own take on the line "Maximum Burn" that Optimus Primal would shout whenever he engaged his flight capabilities in ''Beast Wars''. Considering who's saying the line and the context, it's probably an intentional homage.
*** Soundwave ejecting Laserbeak from his chest in robot mode is a reference to the Breastforce Decepticons and their Breast Animals from ''Anime/TransformersVictory''.
*** Bulkhead actually does a TitleDrop in "Project Predacon".
** '''WesternAnimation/BeastMachines:'''
*** The [[{{Mook}} mooks]] are called Vehicons. Though unlike ''Beast Machines'', they're sentient and ''all'' possess sparks, whereas in ''Beast Machines'' it was just the Generals who had sparks.
*** After being presumed dead, Megatron ends up in a body far weaker than his own. Same thing happened to Beast!Megatron, only more drastically.
*** "T.M.I." also name drops "WesternAnimation/BeastMachines", though in reference to monster trucks.
*** The Spark Extractor that Megatron unearths at the beginning of "Operation Bumblebee" was first used by another Megatron as he conquered Cybertron to remove the sparks from captive Transformers and create his Vehicon soldiers, yeeeessss... ''Prime'''s version is a little more dangerous, though.
*** Optimus' words near the end of "Predacons Rising" [[spoiler: greatly mirror the last words spoken by Optimus Primal before becoming one with the Well of Allsparks.]]
** '''[[Film/{{Transformers}} The live-action films]]:'''
*** Optimus Prime introduces himself and the Autobots to the human kids in a very similar manner to they way his movie counterpart did, and the ending of the FiveEpisodePilot includes him sending a message to space.
*** Bumblebee is unable to speak.
*** The first episode states that the last known activity on Earth of the Decepticons was about three years prior, roughly the time in RealLife that the first live-action Transformers movie was released.
*** Design-wise, Prime Bumblebee is Movie 'Bee in Prime's art style, all the way. Prime Optimus is Movie Optimus without the flame-paint and different shoulders (he's got movie Prime's trademark pop-out cannon and sword, perfectly identical to the movie version.)
*** Prime Starscream's chest looks a lot like Movie Starscream's face.
*** When Laserbeak is on Soundwave's chest, it looks very much like the face of Movie Frenzy. Putting a Frenzy homage in Soundwave is also a G1 homage, sorta (G1 Frenzy, like G1 Laserbeak, was one of Soundwave's cassette minions.)
*** Megatron's jet mode is pretty much Movie Megatron's first alt-mode.
*** She hasn't done it in the show yet, but all of Arcee's toys make her capable of being mostly in robot mode but rolling around on one wheel just like the Movie Arcee trio.
*** It's a stretch, but of the movie Arcee trio, only the ''blue'' one is shown to survive the final battle.[[note]]Before anyone tries to say what "really" happened, let's lay it out: Creator/MichaelBay considers them all dead. The post-ROTF comics consider none of them dead (at least, at the point it takes over. Not everyone from the movie survives the comics' events. If you weren't in DOTM and thus assured survival by canon, you could live or die.) The movie itself shows the intact, alive blue one tending to one of the other two after they get blasted. Which gets most {{canon}} weight in your book is up to you.[[/note]] Prime Arcee is of course blue.
*** In "Out of his Head", Megatron's revival is reminiscent of Optimus's from ''Revenge of the Fallen''.
*** Starscream loses an arm in "Shadowzone", much like his movie counterpart.
*** In "T.M.I.", Bulkhead is driven crazy after having ancient Cybertronian information projected into his brain and starts drawing symbols on any available surface. The same thing happens to Sam in ''Revenge of the Fallen''.
*** Starscream's deeper voice and Igor-ish posture and movement make him reminiscent of movie Starscream more than any other.
*** Nemesis Prime's attack on the military base is quite similar to Blackout's attack on the Qatar base in the first film.
*** [[ConspiracyTheorist Vogel]] believes that [[spoiler:aliens wish to enslave humanity]], which was exactly what the Decepticons planned to do in ''[[Film/TransformersDarkOfTheMoon Dark of the Moon]]''.
*** Shockwave's design appears to be a melding of his G1 incarnation mixed with heavy influences from his ''Dark Of The Moon'' appearance.
*** In "Orion Pax, Part 2", Starscream takes out a flying Vehicon in much the same way his movie counterpart took out fighter jets in the first film.
*** Arcee mentioned the time Team Prime first arrived on Earth and describes how Bulkhead ran into a set of power lines. The same thing happened to Ratchet in the first movie.
*** In "Predacons Rising", [[spoiler:Megatron's corpse is reanimated and files out from the bottom of an ocean]], much like in the second film.
** '''Anime/TransformersArmada:'''
*** Several eps reuse the ''Armada'' IdiosyncraticEpisodeNaming (vauge one-word titles) to indicate the onset of CerebusSyndrome.
*** An episode is named ''Armada.''
*** The Star Saber is a powerful weapon from that series, though it was made of three mini-cons. The ''Prime'' Star Saber's hilt even looks kinda like Sonar's hilt mode (but with one piece broken off.)
** '''Anime/TransformersEnergon:'''
*** The Terrorcons were a sub-faction of Decepticons that were largely mindless drones led by Scorponok that had ties to Unicron. The robot zombies here are named [[AllThereInTheManual Terrorcons in supplementary material]] (and, later, named explicitly as such in the show), and seem to have some related properties.
*** Megatron also uses an extremely powerful sword using energon.
*** [[spoiler: Megatron being possessed by Unicron and driven to the place Unicron needed to reach to fully realize his plans.]]
** '''Anime/TransformersCybertron:'''
*** The ''Cybertron'' series ''also'' had one-word titles.
*** The Omega Lock and the four keys needed to activate it exist in both series and they both can restore the planet Cybertron.
*** The battle in "Alpha/Omega" resembles the final battle between Optimus Prime and Megatron/Galvatron as Optimus wields a large blue sword which belonged to another Prime and Megatron wields a glowing purple blade with a curved edge.
*** In ''Energon'', Megatron was possessed by Unicron, and in Cybertron he has Unicron-inspired designs called the "armor of Unicron" that gives him the Transformer version of dark magic. In ''Predacons Rising,'' Megs [[spoiler: is possessed by Unicron, has some ''Energon''-esque moments, and also gains some physical Unicron-inspired upgrades which he keeps permanently after Unicron is out of his head for good.]]
** '''WesternAnimation/TransformersAnimated:'''
*** Cliffjumper's head design is almost identical to ''Animated'' Bumblebee's design, referencing how they are [[AvertedTrope normally]] [[PaletteSwap redecoes]] of each other.
*** Bulkhead is very similar in design to his ''Animated'' counterpart, as is Ratchet.
*** Starscream's speech to the Decepticons at the end of "Darkness Rising" is quite similar to the one ''Animated'' Starscream gave near the beginning of that show's pilot (both times being when he assumed [[spoiler: that Megatron was dead]]). The difference being that this time he actually gets to finish it... and doesn't get blown up.
*** In a nod to his ''Animated'' counterpart's artistic leanings, Bulkhead spends much of "T.M.I." painting the formula for synthetic energon on any surface he can find.
*** Starscream's chest may be movie Starscream's face, but the scissors-like positioning of his wings in robot mode is straight-up TFA, as is his strokable [[LanternJawOfJustice chin]] and his lower body.
*** Megatron's got pre-Earth TFA Megs' robot mode design (with more spikes.)
*** Starscream also [[spoiler:clones himself in "Armada" much as ''Animated'' Screamer did in Season 2, but none of the clones end up becoming any of the other Seekers and they're all dead by the end of the episode.]]
*** Smokescreen is a member of the [[WesternAnimation/TransformersAnimated Elite Guard]], complete with the wings on the sides of his insignia.
*** In "Darkest Hour", Megatron borrows his TFA counterpart's catchphrase "Decepticons! Transform and Rise up!".
*** ''Animated'' Ultra Magnus wields a powerful hammer. In "Project Predacon", ''Prime'' Magnus decides to put the depleted Forge of Solus Prime to good use.
*** ''Prime'' Shockwave's alt-mode is an H-shaped tank, similar to 'Animated'' Shockwave's, except spikier and more alien-looking.
*** Soundwave's one line that isn't recorded from someone else is "Soundwave superior, Autobots inferior." ''Animated'' Soundwave once said "Autobots inferior, Soundwave superior" (which of course, in turn, homaged G1 Soundwave's "Soundwave superior, Constructicons inferior" when the 'cons argued over who was getting the KlingonPromotion.)
** At one point in "Orion Pax, Pt. 1", Megatron refers back to the "[[TransformersWarForCybertron war for Cybertron]]", and refers to the Transformers as being "[[Literature/TransformersExodus in exodus]]" on Earth. A lot of backstory is taken from ''Exodus'' and ''WFC'', in one of the show's few attempts at falling in line with the WordOfSaintPaul that is ''WFC'', ''Exodus'', and ''Prime'' being set in one continuity.
*** There are more references to other works in the Aligned Continuity in "Operation Bumblebee, Part 2" when a [[TransformersWarForCybertron Nucleon Shock Cannon]] is mentioned by Knock Out as Megatron [[spoiler:tries and fails to build one with the Forge of Solus Prime, one of the Thirteen Primes, marking the first appearance of one of the Artifacts of the Primes in the show that isn't the Matrix of Leadership.]]
** A more meta example: "Nemesis Prime" is centered around a robotic duplicate of Optimus Prime, controlled remotely by Silas. The original version of Optimus (named Battle Convoy) from the Japanese Diaclone toy line was in fact a nonliving mech that needed to be piloted by a human.
** More toy-based ones that aren't just the usual MerchandiseDriven nature: Bumblebee's color scheme for season three didn't have a toy at the time, the Beast Hunters Bumblebee figure being a super-spiky but not recolored 'Bee. However, ''movie'' Bumblebee has ''several'' toys based on the "make the yellow black and the black yellow" idea. Also, one of Uni-tron's Dark Energon constructs were similar to the Arms Micron Hades, and his altmode is similar to Gaia Unicron (toys apparently ''never'' intended for US release and ''definitely'' not used the way the toyline intends, with Hades being normal Megs' mini-con partner a la ''TransformersArmada'' and Gaia Unicron being Unicron's season one stone constructs made more Transformery.)
** Smokescreen, when watching passing vehicles with Jack to decide on an altmode, says he'd consider a concrete truck "if I was a Constructicon".
* NamesTheSame: Miko Nakadai is bored with life and so [[TheLoad constantly gets in the Autobots' way]]. [[Series/BakuryuuSentaiAbaranger Mikoto Nakadai]] is bored with life and so [[SixthRangerTraitor constantly gets in the Abarangers' way]]... by beating the crap out of them.
** It doesn't help that both characters are Japanese, and both shows deal with [[TransformingMecha giant transforming robots]] that can talk.
* NoExportForYou: So far, at least a good third of the tie-in toyline, including the entire ''First Edition'' series, will not be released in the United States... particularly galling since this is where Hasbro's main corporate offices ''are actually located'' and the aforementioned ''First Edition'' series were released in Canada.
** So are the Arms Micron versions of the toyline... and the separate Arms Microns. They're Asia-only.
** And therefore, the same goes for the "Arms Micron Theater" shorts.
** The third season of the show, ''Beast Hunters'', has fallen into this for Japanese audiences. Instead, it's been replaced with a new OVA series entitled ''Anime/TransformersGO!'', which takes place sometime after the missing third season itself. Same with the ''Predacons Rising'' TV movie.
* TheOtherDarrin: Given it's set in the same universe as ''TransformersWarForCybertron'', Optimus Prime is the only character who appears in both ''[=WfC=]'' and ''Prime'' that doesn't undergo this, as PeterCullen voiced Optimus in both. The humans, Bulkhead, Knock Out, Skyquake, Airachnid, Makeshift, Wheeljack, Tailgate, Dreadwing, and Smokescreen didn't appear in the game, and the portrayals of Bumblebee and Soundwave haven't required voice actors [[spoiler: until season three.]]
** FredTatasciore is replaced with Creator/FrankWelker reprising his iconic role as Megatron from ''G1'' and Creator/JeffreyCombs as Ratchet.
*** [[spoiler:When the Nemesis is reanimated (it was technically Trypticon)]] Creator/KevinMichaelRichardson replaces Fred as well.
*** Fred recently found himself on the other end of this trope in [[LicensedGame the game]], filling in for Creator/TonyTodd as Dreadwing.
** [[spoiler: In reprising his other iconic role from G1 as Soundwave, Frank Welker is also this to Isaac C. Singleton Jr.]]
** Creator/SumaleeMontano replaces Creator/KariWahlgren as Arcee.
** Creator/SteveBlum replaces Creator/SamRiegel as Starscream, though Steve is also an interesting case, as he voiced Cliffjumper and Shockwave in ''[=WfC=]'' and the latter again in ''VideoGame/TransformersFallOfCybertron'', yet DwayneJohnson voiced Cliffjumper in "Darkness Rising, Part 1'', then he himself was replaced by Billy Brown in "Out of the Past" while Creator/DavidSobolov replaces Blum as Shockwave in the same episode.
** Creator/AdamBaldwin takes over from Creator/CrispinFreeman as Breakdown.
** Creator/MichaelIronside replaces JamiesonPrice as Ultra Magnus.
** [[spoiler: Creator/WillFriedle replaces Creator/JohnnyYongBosch as Bumblebee.]]
** In the Hungarian dub, Jack, Airachnid, and Alpha Trion get new voices in season 3, with Ratchet joining them halfway through the season. The first two seasons were otherwise consistent (surprising for a Creator/CartoonNetwork dub), only Skyquake's voice changed for a brief flashback.
** The German dub recast Optimus' voice actor after the first season (Reiner Schöne -> Klaus-Dieter Klebsch).
* PlayingAgainstType:
** GinaTorres as Airachnid.
** Creator/DaranNorris as Knock Out.
** Zig-zagged with MichaelIronside as Ultra Magnus. Ironside is well known for playing contemptuous military commanders in live action and his voice acting roles tend to be along the lines of villains or [[AntiHero morally dubious]] heroes. Thus playing a very straight laced military officer is unusual.
* RealitySubtext: "Decepticons! [[Creator/FrankWelker I]] have [[WesternAnimation/TheTransformers returned!]]"
* RecycledScript: In "Armada" [[spoiler: Starscream uses a bunch of protoforms to create a gang of clones to assassinate Megatron. [[WesternAnimation/TransformersAnimated Sound familiar?]] They even use the same number of clones. On the other hand, ''this'' Starscream [[DangerouslyGenreSavvy is aware that they share his traitorous nature]]]].
* RelationshipVoiceActor:
** In "The Human Factor", the Creator/KevinMichaelRichardson-voiced Bulkhead fights the Creator/ClancyBrown-voiced [[spoiler:Breakdown!]]Silas. [[WesternAnimation/ThunderCats2011 We've seen]] [[WesternAnimation/GreenLanternTheAnimatedSeries this before]].
*** Relating to them, [[spoiler: [[Creator/WillFriedle Bumblebee]] is Lion-O and Ragnar]].
** A good bit of the cast is basically a mini ''WesternAnimation/TheSpectacularSpiderMan'' reunion: [[Creator/JoshKeaton Jack]] is Spider-Man, [[Creator/SteveBlum Starscream]] is Green Goblin and Chameleon, [[Creator/KevinMichaelRichardson Bulkhead]] is Tombstone, [[Creator/ClancyBrown Silas]] is George Stacy and Rhino, [[Creator/JohnDiMaggio Vogel]] is Sandman and Hammerhead, and [[Creator/DaranNorris Knock Out]] is J. Jonah Jameson.
** For the ''WesternAnimation/WolverineAndTheXMen'' fandom: [[Creator/SteveBlum Starscream]] is Wolverine, [[Creator/KevinMichaelRichardson Bulkhead]] is Bishop and Shadow King, [[Creator/NolanNorth Smokescreen]] is Cyclops and Pyro, [[Creator/ClancyBrown Silas]] is Mister Sinister, and [[Creator/MichaelIronside Ultra Magnus]] is Colonel Moss.
** [[Creator/JoshKeaton Jack]], [[Creator/NolanNorth Smokescreen]], and [[Creator/GinaTorres Airachnid]] are [[WesternAnimation/JusticeLeagueCrisisOnTwoEarths the Flash, Green Lantern (Hal Jordan), and Superwoman]].
** For ''CowboyBebop'' fans: [[Creator/SteveBlum Starscream]] is Spike Spiegel and [[Creator/DaranNorris Knock Out]] is both Cowboy Andy and Vincent Volaju.
** For ''WesternAnimation/JusticeLeague'' fans: [[Creator/JeffreyCombs Ratchet]] is the Question, [[MichaelIronside Ultra Magnus]] is Darkseid, [[Creator/GinaTorres Airachnid]] is Vixen, [[Creator/ClancyBrown Silas]] is Lex Luthor, [[Creator/AdamBaldwin Breakdown]] is Jonah Hex and Hal Jordan, [[Creator/RichardGreen Skyquake]] is Orm, and [[spoiler:[[Creator/WillFriedle Bumblebee]] is [[WesternAnimation/BatmanBeyond Terry McGinnis]] and Kyle Rayner]].
** [[Creator/AdamBaldwin Breakdown]] and [[Creator/GinaTorres Airachnid]] are [[Series/{{Firefly}} Jayne Cobb and Zoe Washburne]].
* ShortRunInPeru: Canada aired episodes 21 to 23 several weeks before TheHub did, but then stopped until the two stations were roughly in sync in terms of episodes. Singapore, however, aired the three-part season finale several days before North America did.
** It's happened again as of season three, with the first three episodes airing in Singapore (back to back) a week before the first aired on TheHub (on the standard weekly schedule).
** And now Predacons Rising has been leaked a full three weeks before the supposed air date on Internet Streaming Sites.
* TalkingToHimself: With the Vehicon mooks (and later the Insecticons) all being voiced by Creator/SteveBlum, JoshKeaton, Creator/KevinMichaelRichardson, DaranNorris, and Creator/FrankWelker, this is more or less inevitable. Happens in a literal and somewhat humorous sense to [[spoiler:Starscream when he clones himself]].
* WhatCouldHaveBeen: Bulkhead was originally planned to be Ironhide, but the creators realized that they were essentially creating a new version of ''[[WesternAnimation/TransformersAnimated Animated]]'' Bulkhead, so they put him in the show instead. [[spoiler: However, the featurette of the Season 1 set states that Ironhide's death in ''[[Film/TransformersDarkOfTheMoon Dark of the Moon]]'' was what made the crew replace him with Bulkhead.]]
** According to a featurette of the Season 1 set, [[WesternAnimation/TransformersAnimated Lugnut]] was considered to be join the Decepticon ranks, but was ruled out because the makers felt they had too many aircraft on the 'Con's side and he was replaced with Breakdown.
** Smokescreen was going to be the sixth Autobot at the beginning of the show and he would then get killed by Megatron during the season finale. He was replaced by Cliffjumper and his death was moved to the first episode.
** Part of the reason Season 2 has so many storylines is that the writers realized that standalone episodes would be hard to maintain due to the very abundant continuity, so they rushed through the storyline ideas that they had. It makes one wonder what could have happened had they gone through the three years as planned.
** Seaspray was going to appear in season 3, having survived his run-in with Dreadwing. He would have had a personality similar to Quint from ''Film/{{Jaws}}''.
** Grimlock was also planned to appear in the series. It's likely, had he made an appearance in the series, that he would have borrowed from his ''Fall of Cybertron'' design or been redesigned. The Dinobots collectively are actually referenced by Bulkhead and Miko in ''Project Predacon'', so take that as you will.
