* SugarWiki/AwesomeMusic: The [[https://www.youtube.com/watch?v=w1cdZxsafY8 opening theme]] by Takayuki Miyauchi has a grand, orchestral-style intro intercut with a few fleeting moments of equally amazing rock guitar music. The lyrics are extremely catchy and will definitely get fans excited as they chant the lyrics.
* How the Bio Robo uses a real mechanical hand that's to scale with how large the HumongousMecha is supposed to be to pick up the descendants of the people it imbued with Bio Particles in the past. You can really feel the largeness of the robot with these scenes.
* Red One summoning his [[FlamingSword Fire Sword]] for the first time (and every other StockFootage used of it since then). Because special effects were more primitive at the time, they had to use a literal sword doused in gasoline and lit on fire to achieve the practical effects. No CGI fire here!
* SugarWiki/AwesomeMusic: The ending credits of ''Choudenshi Bioman'' doesn't only feature a happy and catchy theme; it also features the Biomen [[{{Bathos}} cleaning the Bio Robot]]. It's an indelible scene that surely comes up to anyone reminiscing about this series in particular.
* The impressive fight choreography between Mika Koizumi/Yellow Four I and Farrah Cat in episode 2 might qualify. Also, the first appearance of Jun/Yellow Four II fits as well, particularly her actress's extensive stunt work that would make Annie from ''[[Series/SpaceSheriffShaider Shaider]]'' proud.
* The Biomen's sheer amount of [[CombinationAttack Team Attacks]] from Laser Swords to Gigantic Arrows as well as blasts of concentrated Bio Particles wreaked havoc among the [[EliteMooks Beastnoids]] all series long. Their swords also have [[ElementalPowers individual abilities]] for good measure.
** Their Team Attacks were so varied even for a Franchise/SuperSentai series that had the Biomen faced off against [[MonsterOfTheWeek Monsters of the Week]] instead of a [[QuirkyMinibossSquad rotation of the same villains]], they'd probably massacre them all in creative fashion every episode (as opposed to just shooting a cannon at them every time).
* The way Mika takes the Anti-Bio-Particle shots from Mason is heartbreaking but amazing when it comes to how she never hesitates to [[HeroicSacrifice take them all for the team]].
** The death of Mika is a true tearjerker but her [[SomeoneHasToDie in-story heroism]] to save the rest of her teammates from the Anti-Bio-Particle Cannon ultimately inspired them to better [[HeroicWillpower harness their bionic abilities]] and [[FightOffTheKryptonite resist their fatal weakness]] in future encounters.[[note]]It also inadvertently better prepared them against the arrival of Silva down the line.[[/note]]
* The first arrival of [[HeroKiller Bio Hunter Silva]] on Earth, with him taking on both the Neo Empire Gear and the Biomen on his own years before the [[KnightOfCerebus DragonRanger]] would do the same thing with Bandora's Forces and the [[Series/KyoryuSentaiZyuranger Zyurangers]].
** He even came with his own [[EvilCounterpart Anti-Bio-Particle]] [[HumongousMecha mech]] known as [[KillerRobot Balzion]] to boot! The fearsome mech has one of the [[https://static.wikia.nocookie.net/powerrangers/images/5/56/CDB-Balzion.png/revision/latest?cb=20231129162920 better robot designs]] of the show, mainly because it gets more appearances than most [[MonsterOfTheWeek Mecha Gigan]].
** SugarWiki/AwesomeMusic: [[https://www.youtube.com/watch?v=SEi-nj8P0AM "Shirogane no Karibito"]] (The Silver Hunter) or Bio Hunter Silva's theme music is quite iconic. Every time it plays, the stakes are upped and anything goes from hereon out.
** Silva is also awesome because of his [[MagnificentBastard determination]] to take down the Biomen in a LastStand even after Balzion is destroyed and becoming the SpannerInTheWorks that led to the Neo Empire Gear's downfall, with him being directly responsible for the deaths of Farrah and Mason.
* The ''Bioman'' GrandFinale. Full stop.
** The episode starts with the Biomen launching the Bio Robot against Dr. Man's final [[{{Robeast}} Neo Mecha Gigan]] he's personally piloting, [[FinalBoss King]] [[https://vignette.wikia.nocookie.net/powerrangers/images/1/1d/King.png/revision/latest?cb=20190221023309 Megas]]. The Bio Robot struggles a bit because King Megas has [[AllYourPowersCombined all of Balzion's Anti-Bio-Particle abilities]], but they triumph with the help of Peebo's Bio Particles boosting Bio Robo's powers.
** After the destruction of King Megas, Dr. Man activates a planet-annihilating Anti-Bio Bomb that was supposed to [[EarthShatteringKaboom destroy the whole Earth]] and everything in it. The Biomen then [[StormingTheCastle follow his escape ship]] back to [[EvilLair Neo-Grad]]. They then face off against the remaining [[{{Mook}} Mecha Clones]] before killing [[DragonTheirFeet Farrah Cat]] inside the base.
** Once the Biomen corner Dr. Man in his headquarters, demanding he defuse his bomb, Dr. Man's biological son [[MoralityPet Shuichi Kageyama]] arrives and shows him a photo of them and Mrs. Kageyama as a family in a bid to have him [[IKnowYoureInThereSomewhereFight remember his humanity]].
** Afterwards, [[https://www.youtube.com/watch?v=mq36QzjlQtY Doctor Man dies]] by [[DefeatEqualsExplosion exploding himself]] while stubbornly [[TheDarkSideWillMakeYouForget denying his humanity]], but this [[BondVillainStupidity somehow]] [[DeathTrap results]] in the bomb emerging from the [[VillainousPlanInertia center console]], allowing Red One to [[WithinArmsReach switch it off]] at 0.14 seconds (14 centiseconds) before exploding.
** Shuichi then tells the Biomen that despite dying as a Mecha Human, the [[HumanityEnsues Dr. Kageyama part of Dr. Man]] unwittingly [[FailureGambit led the Biomen to the bomb]] so they could defuse it and [[SelfDisposingVillain stop him]] from destroying the world.
** From there, Neo-Grad gets buried in snow and becomes Dr. Man's mausoleum. Later, Peebo then says goodbye to the Biomen and Shuichi as he embarks on a new journey to the stars, his mission of saving Earth against the Neo Empire Gear finally fulfilled.
* The existence of the ''[[https://www.youtube.com/watch?v=_qe9UXjer-c Bioman Plus 2 Stage Show]]'' (and [[https://www.youtube.com/watch?v=BHIIiF0XvG8 other stage shows]] like it) that features not only the Biomen from ''Choudenshi Bioman'', but also Shaider from ''Series/SpaceSheriffShaider'' and Machine Man from ''Series/SeiunKamenMachineman''.[[note]]The idea behind the MassiveMultiplayerCrossover is a huge treat to any children of TheEighties who've watched all three series, particularly nostalgic super fans from Japan, France, South Korea, Brazil, and the Philippines.[[/note]]
