- Ace Pilot: Pilot of both Bio Jet 1 and the first Japanese space shuttle.
- Friend to All Living Things: With his Speaks Fluent Animal powers.
- Law of Chromatic Superiority: Shirou can understand animals, but nobody else is shown to have unmorphed powers. He's also the only one to be directly linked to the Dr. Man part of the plot through his father.

- Genius Bruiser: Is both a tough fighter and skilled mechanic.
- Number Two: Becomes the technical second-in-command after Mika's passing.

- The Smart Guy: His knowledge of mechanics through being a race car driver means he often acts as this, occasionally assisting in maintenance to the Bio Robo.
Ryuuta Nanbara/Blue Three
Ryuuta Nanbara/Blue Three | Actor: Akito Ōsuga
- Delinquent: He used to be a delinquent in his teen years, but was inspired to change his ways. His first encounter with Prince reminded him of those times.
- Fragile Speedster: Swift but not so durable.
- Punny Name: His Bioman codename is a pun on how the Japanese pronounce "Bruce Lee".
- Shock and Awe: Elec Sword
- The Lancer: As a former delinquent, he really cements himself in this position once Mika bites it.
- The Sneaky Guy: His years of diving have made him very nimble and thus he is very skilled in stealth techniques.
Mika Koizumi/Yellow Four I
Mika Koizumi/Yellow Four I | Actor: Yuki Yajima
- Anti-Hero: Starts off Type I, though she eventually grows into a full blown hero.
- Fake Shemp: Only appears unmorphed in the first six episodes before she dies.
- Faux Action Girl: In her nine episodes, she doesn't do much fighting.
- Four Is Death: An unintentional case that coincided with drama from behind the scenes.
- Heroic Sacrifice: Died by continually putting herself in the line of fire to protect her friends.
- Killed Off for Real: In Episode 10.
- Shock and Awe: Thunder Sword.
- Taking the Bullet: More like several as she shields her team singlehandedly.
- Tomboy and Girly Girl: Was a more serious tomboy to Hikaru's sensitive Girly Girl.
Jun Yabuki/Yellow Four II
Jun Yabuki/Yellow Four II | Actor: Sumiko Tanaka
- Action Girl: Very much so, especially since her actress did her own stunts.
- The Big Girl: Her actress was a professional stunt-woman, so the character participated in a number of stunts the others couldn't do including high jumps, rope swinging, and even riding on top of moving vehicles.
- Legacy Character: Took over for Mika as Yellow Four.
- Martial Arts Headband: You don't ever see Jun without wearing one (and it fits her role too). Even one episode had this weaponized by the villains by replacing it with a time bomb!
- Shock and Awe: Thunder Sword
- Shorttank: Typically wears one, complimenting her tomboy personality.
- Surprisingly Realistic Outcome: Jun is one of the top archers in the country and was a member of an Olympic team training for the next games. Her suddenly vanishing from society to become a Bioman does not go unnoticed and only an episode or two after she joins the group has her team wondering just where the heck she disappeared to and sends the team captain to go looking for her.
- The Straight and Arrow Path: Is the only one of the Biomen to wield a physical weapon - a bow.
- Tomboy and Girly Girl: Tomboy athlete to Hikaru's Girly Girl.
- Why Did It Have to Be Snakes?: Fears spiders.
Hikaru Katsuragi/Pink Five
Hikaru Katsuragi/Pink Five | Actor: Michiko Makino
- Barrier Warrior: Pink Barrier.
- The Heart: Embodies traditional feminine qualities and plays a lot of support roles.
- Laser Blade: Laser Sword.
- Tender Tears: She's the most emotional of the Biomen and tends to cry easily.
- Tomboy and Girly Girl: Girly Girl to both Yellow Four's Tomboys.
Peebo
Peebo | Actor: Yoshiko Ōta (voice)
- Expy Has a strong resemblance to C-3PO mixed with a Kamen Rider.
- Gender Flip: Even though he's technically a sexless automaton, he addresses himself as a male in the Japanese original. In the English dub however, he was made female.
- The Mentor: To the Biomen, though he's a tad more innocent and energetic than most.
- Robot Buddy: Was created to guard the Bio Particles and assists the Bioman in their missions.
Bio Robo
Bio Robo
- Combining Mecha: Composed of two jets (Bio Jet 1 and Bio Jet 2).
- Humongous Mecha: Your standard Sentai-piloted giant robot.
- Mechanical Lifeform: It is shown that Bio Robo has a will of its own when it runs away during Silva's first appearance.
Neo Empire Gear
In General
"For the Man!"
A society of Mechahumans based from the South Pole who seek to conquer and enslave humanity.- The Empire: Proclaim themselves to be one, though they don't seem to have much territory outside of Neograd. They do aim to expand their grip throughout the world.
- Enemy Civil War: One occurs when the Big Three learn of Doctor Man's hidden identity as a human and plot to overthrow him so the Gear can be ruled by true Mechahumans.
- Gratuitous English: Say "For the Man!" as their salute.
- Killer Robot: Their ranks are full of robots built for fighting.
- The Man Behind the Monsters: The executives of the empire all look like regular humans.
- Mid-Season Upgrade: Doctor Man upgrades himself into Neo Doctor Man halfway through, and later gives each of the Big Three their own upgrades.
- Nebulous Evil Organization: An evil society of robots bent on conquering the world.
- Offscreen Villain Dark Matter: Considering Doctor Man is really a regular human scientist who went crazy and abandoned his family, one has to wonder where he got the resources to build a massive fortress in the South Pole, several Humongous Mecha and a legion of Mecha-Mooks.
- Undying Loyalty: On account of being created by him, all members of the empire are unflinchingly loyal to Doctor Man. Subverted when the Big Three revolt upon learning of Doctor Man's human origins. And then double subverted when Doctor Man crushes their rebellion and reprograms them to be completely loyal to him.
Doctor Man
Doctor Man/Hideo Kageyama | Actor: Munemaru Kōda
- Ambiguous Situation: Whether he deliberately led the Biomen to the Bio Particle bomb or did so unintentionally is a question that's brought up and left unanswered in the series. The Biomen, being idealists they are, believe the former.
- Bad Boss: Is prone to zapping his subordinates whenever they do something to displease him. In episode 9, he zaps Farrah for simply questioning why he gave an order, after she already followed it.
- Big Bad: The ruler of Gear and the one heading up their war on humanity.
- Boomerang Bigot: Despises humans while secretly being human himself.
- Cyborg: Revealed to be one as part of the Mid-Season Twist.
- Cybernetics Eat Your Soul: Invoked this trope on himself to abandon human emotions and become a more calculating leader.
- Dark Lord on Life Support: It becomes apparent halfway through that Doctor Man's body is failing him, leading him to seek out a successor.
- Emperor Scientist: He built the Neo Empire Gear himself and created their legions of robots, and has ambitions of ruling the entire world.
- Even Evil Has Loved Ones:
- While he's cold towards his subordinates, he genuinely cares for his son Prince. It becomes subverted though when Prince develops human emotions, at which point Doctor Man wipes his mind, deeming him a failure and sends him out on a suicide mission against the Biomen.
- Later on, he tries to reconnect with his real son, Shuichi, to try and get him to be his heir. It's subverted again though when Shuichi rejects him and Doctor Man orders his forces to kill him, before converting himself into a full Mechahuman to remove his care for his son.
- Morally Ambiguous Doctorate: That "Doctor" title certainly doesn't come from medical expertise.
- Professor Guinea Pig: Tested his device that increases intelligence on himself, only for it to backfire and turn him old.
- Redemption Rejection: In his final moments Shuichi and the Biomen try to persuade him to embrace his human side again. Doctor Man refuses and ignores them, or does he?
- Suicidal Cosmic Temper Tantrum: Recognizing that he cannot win if King Megas fails, he linked it to a bomb in Neograd set to activate if King Megas is destroyed. It's powerful enough to blow up the Earth to punish humanity for not recognizing his brilliance.
- Taking You with Me: After the Biomen defeat him in King Megas, he attempts to use a Bio Particle bomb to destroy the entire planet for not being able to rule it.
- Villainous Breakdown: He's clearly lost it in his final moments, which he spends giving a delusional rant about being a mechahuman while not recognizing his own son standing before him.
- Walking Spoiler: It's pretty difficult to talk about him without bringing up his origins.
- Was Once a Man: Initially assumed to be a robot like the rest of the empire, he's revealed halfway through to have once been a human scientist, until an experiment went wrong and he converted himself into a cyborg to preserve his life, abandoning his humanity in the process.
- We Can Rule Together: Tries to get his son Shuichi to join Gear and become his successor, but Shuichi refuses.
- Would Hurt a Child: In episode 15 his big plan is to infect scores of children with a deadly fungus, just to analyse how modern medicine is used to treat them, then refine the fungus to overcome any treatment. The children are just the test subjects.
- You Have Failed Me: Oddly averted. While he is a Bad Boss, he seems to be tolerant of failure in his subordinates and even repairs Zyuoh when he's destroyed in battle after Monster collects all his parts.
- Younger Than They Look: Despite looking very elderly, he's really only middle-aged at most, having caused himself to rapidly age through an Experiment Gone Wrong.
Mason
Mason | Actor: Hirohisa Nakata
- The Dragon: The go-to henchman for Doctor Man and leader of the Big Three.
- Hero Killer: Headed the mission that led to Mika's demise.
- Mid-Season Upgrade: Is upgraded to included rockets and missiles in his body.
- Sadist: Unlike Farrah and Monster, who favor stealth and power respectively, Mason seems to only want to cause as much suffering as possible.
- The Starscream: After learning of Doctor Man's human background he orchestrates a coup to overthrow him. Only for Doctor Man to quickly retake power.
- Zeroth Law Rebellion: Technically he was following his directives when he rebelled against Doctor Man. He was programmed to oppose humans and Doctor Man just so happened to be a human.
Farrah
Farrah | Actor: Yōko Asuka
- Evil Genius: Puts more emphasis on subtle plans than her teammates.
- Femme Fatale: Has no issues with going from womanly to deadly.
- Mad Scientist: Often the reason stealth was needed in her missions was so she could collect data and conduct experiments.
- Master of Disguise: Many of her missions involve her disguising herself as a human.
- Smug Snake: Tends to act rather condescending to her fellow Big Three, especially Monster.
Monster
Monster | Actor: Strong Kongō
- Adaptation Name Change: In the Phillipines' English dub, his name was changed to Fargo.
- Bald of Evil: No hair all evil.
- The Brute: Was built by Doctor Man to provide sheer power, and thus is most likely to use physical force in a fight.
- Butt-Monkey: He's basically the Plucky Comic Relief of the villains, and is one most likely to be zapped by Doctor Man and clowned on by the other members.
- Dumb Muscle: Doctor Man even admits to Prince that he built Monster to be strong, but dumb.
- Even Evil Has Loved Ones: Genuinely cares for his Beastnoid Zyuoh, to the point of collecting all his parts when he's destroyed so Doctor Man can repair him.
- Psychopathic Manchild: Most of the time his stupidity equates to him acting like a giant kid. His alignment, however, makes it far worse.
Farrah Cat
Farrah Cat | Actor: Yukari Oshima
- Dragon Their Feet: After Farrah is killed, Farrah Cat lasts until the final episode before being killed off. In fact, she last longer than any other recurring villains in the show (Aside from Dr. Man).
- Evil Wears Black: Wears a black jumpsuit and is a villain.
- Post-Final Boss: She makes one final attack on the Biomen after Doctor Man is fatally wounded with King Megas's defeat, but she proves nowhere near as dangerous, and it's made clear that other than Doctor Man's Suicidal Cosmic Tempter Tantrum, Gear was finished with the previous battle.
Prince
An android created by Doctor Man.
- Walking Spoiler: Hard to mention him a bit when he's made based on Doctor Man's real son, Shūichi Kageyama.
Mechaclones
- Mauve Shirt: Mechaclone No. 1, who's the focus character of episode 28.
- Mecha-Mooks: All of them robots produced by Gear, making them disposable goons that can be sacrificed with little cost.
- Mooks: The grunts of Gear.
Beastnoids
A group of five mechanical monsters used by the Big Three in missions.
- Evil Counterpart: Parodied in episode 31 when they do their own roll call to counter the Biomen's roll call.
- Monster of the Week: Averted. Rather than send out a new monster each episode, Gear instead uses the Beastnoids as recurring monsters on missions.
- Quirky Miniboss Squad: Gear's quirky and colorful team of monsters.
- Two-Faced: Psygorn can rotate his head to reveal different faces with different attacks.
Mecha Gigans
Giant robots that are sent out to fight Bio Robo.
- Humongous Mecha: Giant battle robots.
- Final Boss: King Megas is the final one, and the last opponent the Biomen face.
- Mid-Season Upgrade: Halfway through they're upgraded into the Neo Mecha Gigans.
- Monster of the Week: The Biomen usually have to face one each episode.
Anti-Bio Union
In General
The logo of the Anti-Bio Union seen on Silva's belt.
A faction on Bio Star which opposed the use of Bio Particles, leading them to go to war with the Bio Peace Union 500 years ago.- It's Personal: Gear only fight the Bioman because they stand in their way of conquering Earth. The Anti-Bio Union (Through Bio Hunter Silva) wanted to destroy them simply for having Bio Particles in them.
- Villainous Legacy: They're long gone when the series begins, but their influence still remains through their ultimate weapon, Silva. They also developed the Anti-Bio Particles, which were eventually used by Gear to claim the life of the first Yellow Four.
- Well-Intentioned Extremist: Have shades of this. The reason they went to war with the Bio Peace Union was because they feared the ability of Bio Particles to be used as a weapon.
Bio Hunter Silva
Bio Hunter Silva | Actor: Kazuo Hayashi
- Bad Guys Do the Dirty Work: Silva ends up being the one responsible for the deaths of the Big Three. He fatally injured Monster, held Farrah in place while she was in Balzion so the Biomen could finish her off and killed Mason when he tried to fight him.
- Big Bad: He reappears as one of the main antagonists of Kamen Rider × Super Sentai: Super Hero Taisen.
- Demoted to Dragon: He also becomes one of the secondary antagonists in Kikai Sentai Zenkaiger the Movie: Red Fight! All Sentai Great Assemble!!.
- Breakout Villain: Arguably, one of the most memorable and popular villains in the history of Super Sentai. There's a reason he got brought back as the Big Bad of Super Hero Taisen. He's one of the few villains to receive representation in toylines long after the end of his series, with himself getting a special SHODO Super articulated figure and his mecha, Balzion, receiving a Minipla release; an honor that only the similarly popular Duke Org Rouki has been able to receive as well thus far.
- Blade Below the Shoulder: Both which can be fired like arrows.
- Catchphrase: Hakai! Hakai! Hakai! (Destroy! Destroy! Destroy!)
- Climax Boss: While the Biomen still have Doctor Man to fight after him, Silva is by far their toughest opponent once he regains Balzion. It takes Peebo combining with the Bio Robo to finally take him down.
- The Determinator: He will complete his mission and destroy all Bio Particles, no matter the cost. Even after Balzion is destroyed, he exits the robot to face the Biomen on his own.
- The Dreaded: He possesses Anti-Bio Particles that are more powerful than those used to kill the first Yellow Four (Even though he doesn't manage to kill any Biomen with them). Peebo had a very good reason to fear him.
- Enemy Mine: Defied. Doctor Man proposes one once he finds out Silva also wants to destroy the Biomen. Silva declines, before going a rampage through Neograd.
- Evil Is Not a Toy: Doctor Man immediately takes an interest in Silva once he arrives and tries to get his hands on him and Balzion, which leads to him losing most of his generals at Silva's hands.
- Evil Laugh: Prone to laughing as he's causing havoc.
- Expy: Based on Kikaider's nemesis Hakaider, being a gun-toting Killer Robot bent on fighting the heroes.
- Gone Horribly Right: Was built by the Anti-Bio Union to be their trump card against the Bio Peace Alliance. Silva defeated them, but also destroyed the Bio Star itself.
- Greater-Scope Villain: Silva proves to be a far more imposing threat than the Gear Empire and played a part in the destruction of the Bio Star in the series' backstory, setting in motion the whole events of the series.
- Hero Killer: With the Anti-Bio Particles in his possession, he has the potential to kill the Biomen if he has the chance.
- Humongous Mecha: Silva has Balzion, which was created to combat Bio Robo.
- Karmic Death: After weeks of trying to hunt down the Biomen for wielding Bio Particles, the Biomen use those particles to weaken Silva and Balzion and destroy them.
- Knight of Cerebus: When introduced, Silva gave off an aura of dread simply due to the fact that he wielded Anti-Bio Particles and could cause trouble for both the Bioman and Gear.
- Leitmotif: Whenever Silva appears, This Theme
plays. - Nice Job Fixing It, Villain: He killed off more members of the Neo Empire Gear than the Biomen did.
- Not in This for Your Revolution: The main reason Gear's attempts to ally with him always fail. Silva's sole goal is to eliminate Bio Particles, which means killing the Bioman and destroying Bio Robo. However, Silva does NOT have any intention of destroying Earth or humanity, nor will he cooperate with Doctor Man's plans to do so in order to get at the Bioman. Whenever he runs into regular people, he leaves them alone. Often, him coming to blows with Gear is because their evil plan of the day is counter-productive to just fighting the Bioman, and more than once he just leaves and lets the Biomen save the day. Of course, Silva's still dangerous because he won't balk at collateral damage in his fight either. After all, it's not like blowing up a few cities in attempting to kill the Bioman will end up destroying the planet or humanity.
- One-Man Army: Silva alone has caused more trouble to the Biomen than Gear, a full-fledged empire, ever did. The Biomen themselves admit that between Gear and Silva, Gear are the lesser of two evils.
- The Remnant: He's the last remaining member of the Anti-Bio Union, but that's not going to stop him from completing his mission.
- Wild Card: Fights against both the Bioman and the Gear and has no loyalty to either side.
