* ActorAllusion: In "The Agenda: Part Three", Silverbolt looks up at Venus in the sky and says it reminds him of Blackarachnia. Blackarachnia's voice actress is Venus Terzo.
* AscendedFanon: The Predacon base's name, "Darksyde", came from a {{fanon}} [[{{Mondegreen}} misinterpretation]] of a line spoken by Terrorsaur in the episode "Equal Measures". ("Welcome to the dark side!") It was given an official name first in the ''Beast Wars Transmetals'' video, and then in the {{prequel}} video ''Dawn of Future's Past''.
* DeletedScene: The final episode had a short deleted scene where they put the original Megatron's spark back into his body, resolving what seems like a pretty big oversight in the final cut.
* FakeRussian: For whatever reason, Ravage was given a Russian accent.
* FanNickname: Dinobot '''is''' [[MemeticMutation Raptor Jesus!]]
* HeyItsThatVoice:
** Creator/GaryChalk voices Optimus. TakehitoKoyasu is his seiyuu in the japanese version.
** DavidKaye is Megatron.
** Creator/ScottMcNeil voices Dinobot, Waspinator, Rattrap and Silverbolt.
** Rhinox has the same voice actor as M. Bison from [[WesternAnimation/StreetFighter the American cartoon]]. '''YES YES!!!'''
** Airazor is Ocean-dub [[DragonBall Freeza]]!
** Creator/DavidSobolov is Depth Charge.
** Blackarachnia is voiced by Creator/VenusTerzo. Creator/RyokaYuzuki is her Japanese voice.
** Creator/NobuyukiHiyama is Rampage's Japanese voice.
** Cheetor and Sea Clamp (and Quickstrike in the ''Transmetals'' game) are voiced by Creator/IanJamesCorlett, who also voiced [[WesternAnimation/AdventuresofSonicTheHedgehog Coconuts]] and [[WesternAnimation/MyLittlePonyFriendshipIsMagic Silver Shill]], among other roles.
* PromotedFanboy: Benson Yee, operator of the popular web site bwtf.com and convention visitor. He was approached for G1 knowledge and received a 'consultant' credit in certain episodes. There's a lesser version of this where several fans get minor mentions in-series (usually in the names of sectors on the map and such).
** In the episode "Dark Designs", Waspinator receives what seems like brain damage, and is called wacko. He responds by calling himself Wonko The Sane, the name of a moderator from a G1 fan chat room.
* RelationshipVoiceActor: DavidKaye is a fearsome BadAss, while Don Brown is his somewhat more comedic second-in-command - not only here, but in ''{{Inuyasha}}''.
* SerendipityWritesThePlot: The reason why there are so few characters [[LoadsAndLoadsOfCharacters compared to G1]] is because CGI was quite expensive when it was created, forcing the creators to limit the number of characters on each side. Of course, fewer characters meant a stronger focus on the characterization of the existing characters, so it wasn't all bad.
* TechnologyMarchesOn: The Maximals are several times seen using data discs that strongly resemble floppies.
** Towards the end of "Dark Designs," when Cheetor asks Rhinox what it was like to be a Predacon, he answers "it's like you're three gigabytes of attitude on a two-gig hard drive." No, he didn't say flash drive, he said ''hard drive''.
* WhatCouldHaveBeen:
** Waspinator was going to be sacrificed at the beginning of the second season, but [[PopularityPower his popularity]] as TheChewToy saved him, with [[spoiler:Terrorsaur]] being sacrificed instead. [[spoiler:Scorponok]] was already planned to die, however, because [[spoiler:Inferno was a more entertaining character and would serve as TheDragon to Megatron even better]], giving him little reason to remain alive. Both characters who perished did so because the costly limitations of CGI at the time (which lead to a limited character count) meant that characters needed to be removed so that new ones could be introduced and [[MerchandiseDriven promote the toyline]], among other things. Incidently, this also lead - in part - to the meticulous plotting of [[spoiler:Dinobot's redemptive StoryArc]], so some good came out of it all by the end.
** Waspinator and Rhinox had Transmetal toys in the toy line, even though they never changed bodies in the show. This becomes an important point for Rhinox if you support the theory that he [[spoiler: decides that Cybertron should be made purely technological in ''BeastMachines'']] because he had become hateful of his comparatively useless beast mode.
** "Dark Glass", a very dark episode since scrapped that would've filled in a nasty little PlotHole dealing with Dinobot's EvilKnockoff during the series' finale.
** For the series finale, Mainframe wanted to have the Maximals fly the ''Ark'' and engage the ''Nemesis''. On top of that, the ''Nemesis'' would have been manned by revived [[Franchise/TransformersGeneration1 Decepticons Thrust, Dirge and Ramjet]]. Budget and time constraints force them to drop the idea.
*** On top of that, it was originally intended that the two-part GrandFinale was meant to only conclude Season 3 - except as a ''three''-part story, with the preceeding Vok-based episode (that introduced Tigerhawk) being the 1st episode. It would have explained Tarantulas' past and motives in greater detail and revealed the reasons for his hatred of the Vok. When ExecutiveMeddling (the desire to create the [[BrokenBase controversial]] ''WesternAnimation/BeastMachines'') kicked in and resulted in Season 3 being the last season (dropping a potential Season 4), this idea was scrapped and the resolution to the "Tarantulas vs. the Vok" became an AbortedArc. Remnants of the writers' idea ''do'' appear in the SpinOff comics, however.
** In "The Agenda, Part 2", the writers wanted Creator/FrankWelker to reprise his role as [[Franchise/TransformersGeneration1 G1 Megatron]]. Sadly, M. Welker had a very busy schedule and the cost involved for just a few lines prompted the writers to drop the idea. Creator/GaryChalk filled-in for the role.
*** In this very same episode, when Ravage transforms in cassette mode, the original [[ThemeTune Transfomers cartoon theme song]] was meant to be played. However, copyright issues complicated things so the idea was scrapped.
** Speaking of Megatron and Creator/GaryChalk, he originally auditioned for ''this'' show's version of Megatron. The role went to DavidKaye, however, and he ended up voicing Optimus Primal instead.
** Insecticon - one of the first Predacon toys to be released - was originally going to be featured in this series, most likely as part of the original Predacon line-up. This appears to have been learned when Ben Yee's website featured a script draft of "Power Surge" in which Insecticon had dialogue.
** "Fallen Comrades" was originally going to introduce Wolfang. Of course, between a certain new toy about to come out, Wolfang's own toy being old news and that tinkering Cheetor's existing character model/design would save time and money, Tigatron was used instead.
** Along with ''Dark Glass'', there were two other episodes that never got made.
*** The first, '' A Greater Ape'', would feature Optimus believing himself to be a real gorilla after a blow to the head. He would later join a gorilla troop and fall in love with a female ape before an attack by the Predacons would jog his memory. It wasn't made due to the number of new models that would have to be made for the episode.
*** The second, called ''Bitch Wars'', (which was ''hopefully'' just a working title) would have Airazor and Blackarachnia leaving their factions, then teaming up and [[StartMyOwn start their own all-female faction.]] It was not made because the writers had no idea how to deal with the concept realistically.
** Rattrap was going to be a more tragic figure. Based on the exposed "brain" on his toy, Rattrap was going to be heavily malformed due to faulty scanning equipment. Over the show, Rattrap would learn to [[InspirationallyDisadvantaged overcome his disabilities]] and become a [[HandicappedBadass competent warrior]]. It was scrapped because the technology was not yet able to render his organic innards correctly.
