* Shockwave wields The Immobilizer, a weapon that debuted in ''WesternAnimation/TransformersPrime'' and largely shows to function similarly.

* Megatron refers to the final battle of the war on Earth when the Decepticons had the [=AllSpark=] and planned to use it to create a new protoform army as "our Darkest Hour".

* Much like his ''Cyberverse'' counterpart, with whom he shares a toy mold with, Shockwave transforms into a 4 legged walking tank, though the onscreen design is wildly different from the toy.

* Shockwave is shown to be ''severely'' at odds with Megatron. While the circumstances behind this particular instance are new, the concept itself is ''absolutely not''.

* Skywarp attempts to cut off Prime's arm with a buzzsaw hand. While not a notable ''Skywarp'' trait, it is a notable feature of the ''Movieverse'' Starscream. This is yet another example of the franchise making use of the shared body type link seen in many installments from the past.

* Alex refers to Elita-1 doing a move called "Ariel's Gambit". "Ariel" being Elita's name prior to getting rebuilt by Alpha Trionin the original G1 cartoon.

* When trying to get the Emberstone to repeat the process of creating new Terrans, Alex encourages the kids by saying they have "[[WesternAnimation/TheTransformersTheMovie the touch]]"

* Swindle's brother, Hardtop. The character name was first used in the ''Transformers'' franchise in the ''Anime/TransformersCybertron'' toyline, and was recolored in the toy line for the first live-action film. ''[=EarthSpark=]'' marks the character's big debut in animated media, and as if that wasn't enough, his relation to Swindle is ripped straight from the ''Cybertron'' toy's bio.

* Wheeljack makes reference his drones being one of his better inventions as they haven't had any accidental self-desutrctiosn...yet. A reference to Wheeljack's inventions in the original G1 cartoon tendency to blow up or malfunction, also a longtime fandom running joke.

* Transformers comics exist in the show's universe that seem to take stylistic ques from the [[ComicBook/TheTransformersMarvel 80s Marvel Transformers comic]]

* The flashback story told by Alex to the kids is presented in a hand-drawn art style resembling [[WesternAnimation/TheTransformers the original 80s cartoon]], complete with an AspectRatioSwitch to the 4:3 ratio used by analog televisions of the time, and [[StylisticSuck blatant animation errors]].

** After a decade of being a tank or "Cybertronian jet" in animation, Megatron is once more a twin-rotor aircraft, just like in ''WesternAnimation/TransformersAnimated''. The fusion cannon splits in two and forms the tips of the aircraft's width, similar to his stealth bomber form from ''Spotlight: Megatron''. His design cues in general evoke his Alex Milne-based designs from ''ComicBook/TransformersMoreThanMeetsTheEye''. Much like the latter version, this Megatron has made a HeelFaceTurn, though he's still outwardly a Decepticon.
** Also like in ''Animated'', the series takes place after the war between the Autobots and the Decepticons has ended.
** The town of Witwicky, Pennsylvania is named after the [[WesternAnimation/TheTransformers Witwicky]] [[Film/TransformersFilmSeries family]].
** Dr. Mandroid's hatred for all Cybertronians, regardless of faction or origin, to the point of turning himself into a cyborg to fight them, and ironically becoming less humane than even some Decepticons, all call to mind the human villain Circuit Breaker from [[ComicBook/TheTransformersMarvel the Marvel Comics run]].
** Soundwave's alt-mode is a stealth bomber similar to his alt-mode in ''Anime/TransformersCybertron''.
** Dot affectionately refers to Megatron as "Megs", a name ''WesternAnimation/BeastWars'' Megatron was referred to as once and has since become a common FanNickname for all incarnations of Megatron.
** Swindle's brother, Hardtop. The character name was first used in the ''Transformers'' franchise in the ''Cybertron'' toyline, and was recolored in the toy line for the first live-action film. ''[=EarthSpark=]'' marks the character's big debut in animated media, and as if that wasn't enough, his relation to Swindle is ripped straight from the ''Cybertron'' toy's bio.
** According to Alex, the Transformers first came to Earth on September 17, 1984 - the same date [[WesternAnimation/TheTransformers the original series]] made its television debut.
