* ActingForTwo:
** Optimus Primal and G1 Megatron are both voiced by Creator/GaryChalk.
** Rattrap, Dinobot, Silverbolt and Waspinator are voiced by Creator/ScottMcNeil.
** Cheetor, Sentinel and the Maximal Computer are voiced by Creator/IanJamesCorlett.
** Rhinox and the Vok are both voiced by Richard Newman.
** Tigatron/Tigerhawk, the Vok and Unicron are voiced by Blu Mankuma.
** Terrorsaur and Starscream are both voiced by Doug Parker.
* 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 game, and then in the {{prequel}} video ''Dawn of Future's Past''.
* ChannelHop: After ''Westernanimation/BeastMachines'' began on Creator/FoxKids, edited reruns of ''Beast Wars'' made their way to that block.
* 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!]]
* MarketBasedTitle: Canadian regulations do not allow a children's show to have the word "war" in its title, thus the show is called ''Beasties'' in Canada. Don't tell the really sensitive walks of fandom this; we'll ''NEVER'' hear the end of it.
* 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, an online handle for Ben Yee.
* RelationshipVoiceActor: DavidKaye is a fearsome badass, while Don Brown is his somewhat more comedic second-in-command - not only here, but in ''Anime/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''.
* TheOtherDarrin: A few G1 cameos pop up with speaking roles. However, their VAs were either busy (G1 Megatron) or deceased (Starscream).
* UnfinishedEpisode: At least three such episodes are known. The most famous is ''Dark Glass'', a planned Season 3 episode which would have detailed Rattrap's attempts to upload the memories of the original Dinobot into Dinobot II, thus partially filling in a major PlotHole in the SeriesFinale. It is believed to have been scrapped because the story was too dark and not action-packed enough, although the writers have, likely due to misremembering, at times suggested other reasons. Two other unproduced episodes were given the {{working title}}s ''A Greater Ape'' and "''Bitch Wars''" -- the former was about Optimus believing himself to be a real gorilla, even joining a group of them, and was canceled because of CGI limitations; the latter was to be GirlsNightOutEpisode but the concept didn't make much sense.
* 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, Mr. 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.
*** Early in the series' development, the crew wanted to have Chris Latta reprise his role as Starscream. Unfortunately, he died in 1994, two years before "Possession" aired, and had to have Terrorsaur's VA, Doug Parker, impersonate him.
** Speaking of Megatron and Creator/GaryChalk, he originally auditioned for ''this'' show's version of Megatron. The role went to DavidKaye, however, and Chalk 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 has 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 the fact that tweaking 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 have featured 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 been required for the episode.
*** The second, called "Bitch Wars" (which was ''hopefully'' just a working title), would have had 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.
** In the script for the episode "Coming of the Fuzors, Part 1", the blanks (protoforms without sparks) were originally referred to as "roc-shaan" as a TakeThat to Raksha, a Transformers fan notorious for viewing the Decepticons as the real heroes who was also notable for disliking ''Beast Wars''.
** The fourth season would've had the show leave Earth and go into space to chase Megatron after he escaped in the ''Nemesis'', with the series rechristened as ''Beast Hunter's''. A planned subplot would've been the Maximals questioning if they can trust Tigerhawk since he was a Vok emissary, G1 Megatron's Spark trying to take control of his descendant's body, and the Coneheads being recurring villains.
