- Combining Mecha: All Chouseishin can combine with Guntrass to form Daisazer
- Transforming Mecha:Chouseishins can transform into both animal modes and warrior modes.
Warp Monarch
In General
- Aliens Are Bastards: A horde of various aliens responsible for exterminating the ancient humans out of xenophobia. At least that's how it seems at first.
- Anti-Villain: They're only attacking humanity because they believe them to be the descendants of the Bosquito. The reason why they destroyed the ancient Earth civilization several million years ago was because the Bosquito had already overtaken it and they wanted to stop it from expanding to other planets.
- The Empire: Subverted. The only reason they're attacking Earth is because they were tricked by Belzeus into thinking the humans were Bosquito.
- The Federation Ultimately closer to this than The Empire, as they are an alliance of alien planets who are only targeting Earth because they believe humanity to be the descendants of the Bosquito.
- Godzilla Threshold: Their extermination of ancient human civilization was to prevent Bosquito's proliferation, as the ancient Earth was overrun by them.
- Omnicidal Maniac: At first they are implied to be hell-bent on the extermination of current humanity and actually have already exterminated at least one ancient human civilization. Turns out to be heavily subverted, because said extermination was a last resort against Bosquitos who already overrun the ancient Earth (the ancient humans even actually requested their help), and in present day they got deceived by Belzeus into thinking that current humanity are descendants of Bosquito.
- Skeleton Government: We see very little of how the Warp Monarch are actually governed. Based on words from Logia and Belzeus, the Warp Monarch seems to operate on a council system, with an Energy Being embodying the universe's collective consciousness acting as their ultimate decision maker.
- Spell My Name With An S: They've been alternately referred to as "Warp Monarch", "Uofu Manafu", "Wolf Monarch", "Wolf Manaff" and "Gofu Manafu", sometimes multiple within the same episode.
- Time Abyss: They've existed as a faction for hundreds of millions of years, given how the last time they came to Earth was 400,000,000 years ago.
- Unwitting Pawn: They are merely being used by Belzeus to wipe out humanity so he can claim Earth.
- Walking Spoiler: They are not your usual evil interstellar Empire.
Akelons
Karin Saeki
Karin Saeki
Portrayed by: Mika Chiba
Click here to see her Akelon form
An Akelon who took the form of deceased physicist Karin Saeki as part of a plan to destroy the Gransazers by playing them against each other.
- Arc Villain: The villain of the first arc comprising the first twelve episodes.
- Divide and Conquer: Her plan is to play the Gransazers against each other by convincing the Wind Tribe that the other Tribes are malicious and using them to destroy them.
- Dead Person Impersonation: The real Karin Saeki died decades before the start of the series.
- Even Evil Has Loved Ones: She did come to love Akira by the end. Even if that means killing all of humanity save for him.
- Manipulative Bastard: Manipulates the Wind Tribe into seeing the other Gransazers as enemies and attacking them. With Akira specifically, she plays on his crush on her to keep him loyal.
- Not Zilla: Her kaiju form resembles Godzilla quite a bit, except it's colored pink instead of black.It seems quite ironic considering that the series was made by Toho.
- One-Winged Angel: Transforms into a "Great Star Beast" to make a last stand against the Gransazers.
- Starter Villain: She isn't fought until 11 episodes in, but she's the first evil alien the Gransazers do battle with, after the Gransazer-on-Gransazer fighting is stopped.
Clo-Akelon
Clo-Akelon
- Generic Doomsday Villain: It lacks any sort of motivation for its rampage. Somewhat justified as it's little more than a weapon given a very base level of sentience.
- Interim Villain: While it was created from an Akelon, it's one of the few villains in the series not to be working for Warp Monarch.
- Living Weapon: Was originally intended to be a weapon for the JSDF. Things didn't end up going as planned.
Ruby
Ruby
Portrayed by: Marie Sada
- A Form You Are Comfortable With: Unlike Karin, Ruby appears to have taken a human form because her Akelon form would be too off-putting for the Gransazers.
- Good Counterpart: To Karin, being an Akelon who genuinely seeks to help the Gransazers and humanity.
- Light Is Good: Wears a white hood and cloak, and is one of the few helpful aliens we see in the series.
- Mysterious Waif: From her first appearance it's unclear who she is or what she's on Earth for.
- Not Quite Dead: Seemingly dies when Gorgion suicide bombs her, but she pops back up later when Tenma meets with the Warp Monarch's Will.
- Token Good Teammate: One of the few Warp Monarch members we see who isn't malicious at all, instead hoping to save humanity.
Impactors
In General
A trio of aliens capable of assuming robotic warrior forms. They herald from a warrior culture based on pride.
- Always Chaotic Evil: All of the Impactors we've seen have been evil Proud Warrior Race Guys. Subverted by Logia when he pulls a Heel–Face Turn.
- Dark Is Evil: Their armored forms are mostly black colored.
- Evil Virtues: They may be ruthless, but one thing the Impactors share is a sense of camaraderie. Even if they don't like each other, if one of them is killed the others will fight to the end to avenge them.
- Fatal Flaw: Their pride and overconfidence, which is the main trait that distinguishes them from the Gransazers. Each of them could take on the individual Gransazers one-on-one, but because they're so insistent on fighting their battles alone instead of working with each other, they usually wind up outmatched whenever they're up against multiple Gransazers.
- Human Aliens: They look just like humans under their armor.
- Proud Warrior Race Guy: All of them are very proud, arrogant warriors.
- The Psycho Rangers: Their armored fighting forms resemble dark versions of the Gransazer tribes.
- Sinister Shades: They tend to wear red or black sunglasses in their human forms.
- Terrible Trio: Subverted. While there are three of them, they never actually show up all at once to form one.
Logia
Logia

Click here to see his armored form
The commander of the Impactors. He infiltrated the JSDF in the guise of Shuichi Hoshiyama, a lab assistant to Professor Wakui. Logia is one of the more complex characters in the show, initially appearing pragmatic and mission-focused until his desire for revenge leads him to stay on Earth so he can settle his rivalry with Tarious.
- Alternate Company Equivalent: Of both Hakaider and Bio-Hunter Silva, being a pistol-wielding, armored robotic rival and Evil Counterpart obsessed with defeating the hero.
- Arch-Enemy: Becomes one of the most recurring and personal foes for the Gransazers, particularly Tenma.
- Arc Villain: He's the main threat of the second arc comprising episodes 13-24, which concern his scheme to hijack Guntras. Although he keeps reappearing even after the arc ends.
- Avenging the Villain: The main reason he stays on Earth even after being recalled is to avenge Radia and Lucia by defeating the Gransazers.
- Enemy Mine: After Belzeus steals DaiLogian from him, Logia shows up to assist the Gransazers multiple times.
- Gunslinger: Wields a long-range pistol called the Hiro-Sniper and is quite adept at aiming with it.
- The Heavy: He's the most prominent Warp Monarch agent shown and the most recurring foe of the Gransazers.

- The Strategist: Logia is good at formulating strategies in advance and usually doesn't act until he has a plan thought up.
- Unexplained Recovery: Blows himself to bits as part of a Villainous Breakdown, but returns later, with no explanation given, other than “his anger allowed him to survive”.
- Villainous Rescue: In #48 he shoots Brighton after he tries to sneak attack Tenma.
- Worthy Opponent: Gradually comes to see Tenma as a worthy foe.
Lucia
Lucia
Portrayed by: Chisun
Click here to see her armored form.
One of two Impactors who initially arrive on Earth. Acts as Logia's direct subordinate.
- Alas, Poor Villain: Her last ditch effort to defeat the Gransazers results in her death, which drives Logia to a Roaring Rampage of Revenge. Made sadder by the fact that the Gransazers did everything in their power not kill her, but she still passed away as a result of using the Accelerator.
- Climax Boss: After powering herself up with an Accelerator, she becomes the first opponent that the Gransazers form DaiSazer to fight.
- Dark Action Girl: She's an Action Girl and she's fighting on the side of the villains.
- The Dragon: Acts as Logia's main henchwoman once he shows up.

Portrayed by: Tadashi Wakabayashi (voice)
- Conspicuous Trenchcoat: Wears a black trenchcoat which covers his whole body.

- Satellite Character: He appears for just one seen and doesn't even get a name, only being defined by his relation to Logia.
Garbans
In General
The final set of foes the Gransazers face, a race of warlike aliens at the forefront of the Warp Monarch's invasion force.
- Attack Reflector: The Garbans we see have energy barriers that can reflect the Gransazers' attacks back at them.
- The Conspiracy: Several are involved in one with Belzeus to fool the Warp Monarch into thinking the humans are Bosquito and locate the Communicator.
- Spikes of Villainy: All Garbans seem to have at least one or two spikes protruding from their heads.
Belzeus
Belzeus

- Authority Equals Asskicking: He's the leader of the Garbans and the strongest among them, able to outmatch each of the Gransazers when he takes to the field.
- Bad Boss: Sends Luka to her death by having her unseal a dangerous Omnicidal Maniac as part of his Evil Plan. He even outright tells her she's disposable.
- Big Bad: He's the head of the Warp Monarch's Earth invasion and the one behind it being declared in the first place. He smeared humans as descendants of Bosquito in order to get Warp Monarch to go to war against them, allowing him to conquer the planet as the first step of his plan to become a Galactic Conqueror. In short, everything bad that happens is ultimately because of him.
- The Chessmaster: Fooled an entire intergalactic government into thinking humans were Bosquito and successfully unsealed a member of said Bosquito and got away with it in order to get the Warp Monarch to attack the Earth in full fury.
- Corrupt Politician: Is a member of Warp Monarch's highest council and is repeatedly shown using his position to advance his personal ambitions. He lied to get the Warp Monarch to invade Earth and used them as pawns for his goal of galactic conquest.
- Despotism Justifies the Means: Perfectly willing to instigate the genocide of an entire species just so he can use their planet as a stepping stone to grip the universe.
- Diabolical Mastermind: Holds a high-ranking position in The Federation and orchestrates multiple complex schemes in order to make himself the most powerful being in the universe, including commandeering the Warp Monarch's invasion fleet to effectively be his own private army and making use of assassins who answer only to him to eliminate anyone in his way. He's verging on being an Evil Overlord, and has his sights set on becoming a Galactic Conqueror
- Evil Laugh: He just loves laughing when his plans are going as planned.
- Galactic Conqueror: Seeks to become one by capturing Earth, which happens to be a strategically important point that will allow him to "grasp the universe".
- Genius Bruiser: In addition to being a cunning Chessmaster, he's also able to take on and defeat multiple Gransazers.
- Gold-Colored Superiority: He has much more gold on him than the other Garbans that appear and is the most powerful Garban seen.
- Last Villain Stand: After Ran gets the Warp Monarch's Will to call off the invasion, Belzeus attempts to use Cabyron to destroy the Gransazers. His own "Last Stand" lasts for about 30 seconds, and instead of getting killed in a battle he got arrested by Logia.
- Near-Villain Victory: Almost succeeds in killing Ran, which would had left humanity with no other way to contact the Warp Monarch's Will and expose the truth about humanity.
- The Voice: In his first appearances he's just a voice speaking to Logia and Luka. It takes several episodes for him to appear as a hologram and it isn't until the final three episodes that he appears in person.
- Walking Spoiler: He is the true Big Bad of Gransazer and is intrinsically tied to a number of plot twists later in the series.
Brighton
Brighton
Portrayed by: Tachi Kuwabara
- Ambiguously Human: He appears human, but it's unknown if he's a Human Alien or a Garban or some other alien in human disguise.
- "Ass" in Ambassador: Though in this case, his assholeishness comes from the fact that he tricked Ran into believing she was a Humanoid Abomination so she'd try to kill herself.
- Dirty Coward: Pretends to beg for his life when he's confronted by our heroes so he can launch a sneak attack on them. Thankfully he's killed by Logia before he can do so.
- Evil Genius: Of Belzeus' crew. He uses deceit to locate the Communicator and leaves the dirty work up to Algol.
- Faux Affably Evil: At first he appears affable and genuinely committed to a peaceful resolution of the conflict. It soons becomes apparent however that he's really just manipulative and self-serving.
- He Who Must Not Be Seen: Assuming his human form is just a disguise, we never see what he truly looks like.
- Manipulative Bastard: Deceived Ran into thinking she's a Bosquito so she'd offer herself up to be killed.
- Non-Action Guy: Averted. While he leaves most of the fighting to his henchman Algol, he's perfectly capable of fighting himself using electric attacks.
- Shock and Awe: He's capable of shooting electric pulses as attacks.
Algol
Algol
Portrayed by: Ryuta Izumi (voice)

- Early-Bird Cameo: He made his first appearance at a live show that premiered one week before his first episode aired.
- Suicide Attack: Suicide-bombs Ruby to complete his mission.
Cabryon
Space Beast Cabryon
- The Dragon: Fitting, as it's basically a space dragon. It's also Belzeus' trump card.
- Final Boss: The very last enemy the Gransazers face, as Belzeus got apprehended rather quickly by Logia after it's destruction.
- The Juggernaut: Cabryon is hands down the strongest opponent the Gransazers fight in the series. It brushes off all of the Chouseishin's attacks, lays waste to Guntras while preventing Daisazer's formation and decimates all of the individual Chouseishin once they're separated.
- Our Dragons Are Different: It's a giant fire-breathing alien kaiju that for all intents and purposes is a dragon.
Other Warp Monarch Aliens
Gig Fighters

- Cyber Cyclops: Each sees through a single red eye in the center of their heads.
- Mecha-Mooks: Mechanical, easily disposable grunts.

Portrayed by: Kosuke Tomita (voice)
An alien from planet Shuor who possesses an old friend of Professor Horiguchi's as part of a plan to target the Gransazers.- Divide and Conquer: Plotted to split up the Gransazers, but didn't get very far with it.
- What Happened to the Mouse?: After he's caught, he tells the Gransazers they won't win before running off and never appearing again.
- You Can't Thwart Stage One: Subverted hard. His plan is thwarted before it can even begin when the Gransazers stop him from possessing Professor Horiguchi.

Bisil
Portrayed by: Matsuo Matsuo (voice)
- Insectoid Aliens: Their heads resemble cockroaches.
- Spell My Name With An S: Bisil, Bizel, Bisur, Vizel or Visur?

Luka
Luka
Portrayed by: Eri Otoguro
- Because You Were Nice to Me: The main reason she helps Tenma is because he saved her after she was attacked by the Bosquito.
- Heroic Sacrifice: Uses the last of her life force to heal Tenma after he takes an attack from Bosquito for her.
- Token Good Teammate: While distrustful of humans at first, she isn't really evil at all and only does bad things because she's forced to.
- Unwitting Pawn: Belzeus orders her to revive the Bosquito with telling her what exactly she's giving her life force for.
Warp Monarch's Will
Warp Monarch's Will
Voiced by: Hiromi Muraishi
- Abstract Apotheosis: According to Ruby, it embodies the universe's collective will.
- Artificial Intelligence: It behaves less like a sentient being and more like a computer system. It answers all of Tenma's questions, but is unable to take action unless fed the proper information.
- Energy Being: It takes the form of a blue sphere of energy with several smaller spheres moving around it, resembling an oversized atom.
- Greater-Scope Paragon: It turns out to be the greatest force for good in the setting. Once it receives the truth from Ran, it is able to spread it throughout the rest of the Warp Monarch and call off the invasion.
- Last Episode, New Character: It only appears in the final episode.
Other Aliens
Freedo
Freedo
Portrayed by: Mark Okita (voice)
- Cowboy Cop: He uses some incredibly unscrupulous tactics to get Jin to help him stop Freedo.
- Space Police: An officer in an intergalatic police force.
- Unscrupulous Hero: Wants to stop Freedo, but isn't above stuff like threatening Jin's friend to get him to help.
Kriminel
Kriminel
- Bilingual Bonus: Given how this is a Japanese series, an alien crook having a name that sounds like "criminal" is definitely this.
- Cop Killer: Killed Freedo's partner and stole his gun.
- Filler Villain: Not connected to the Warp Monarch at all, and apart from giving Jin some time in the spotlight the episode he's in doesn't advance the plot at all.
- The Voiceless: Never utters a word utter than grunts and growls.
Bosquito
Bosquito
- Absolute Xenophobe: Will attack anything that is not a Bosquito.
- The Dreaded: The Warp Monarch were willing to orbitally bombard an entire planet just to kill it.
- Energy Absorption: Capable of absorbing energy from sapient lifeforms to create more of their kind.
- Greater-Scope Villain: It was the true cause of the Warp Monarch's attack on Earth, as they only did so in order to stop it from threatening the rest of the universe, something which set the stage for the whole series. Belzeus would later use the fear they have of it returning to justify his own invasion of Earth.
- It Can Think: It appears to be a feral beast at first, but at several points the Bosquito demonstrates it may be smarter than it appears. It uses a TV to hunt for places where lots of humans are, identifies a device Professor Horiguchi attempts to seal it with and destroys it before it can be used, and is fully capable of hijacking and piloting Chouseishin.
- Me's a Crowd: It can create more of itself once it gains enough energy from absorbing other lifeforms.
- Sealed Evil in a Can: A single Bosquito was left sealed on Earth. It gets set free by an unwitting Luka.
- Sixth Ranger Traitor: The Gransazers at first believe its their thirteenth member. It very quickly proves them wrong.
- Truly Single Parent: Bosquito reproduce by absorbing energy from other lifeforms and using it to "bud" more Bosquito.
- Walking Spoiler: The Bosquito are at the center of a number of major plot developments late into the series, most of all the true cause of Warp Monarch's invasion millions of years ago.
