This is a partial character sheet for Kamen Rider Ghost. Visit here for the main character index. Subjective trope and audience reactions should go on the YMMV page.
The Gamma are the main antagonistic force in Kamen Rider Ghost. A race of demonic spirits from another realm that can be summoned into our world through a magic portal known as a Gamma Hole. These are the work of the Mysterious Man, a black-clad sorcerer, though it is unknown if he's working with, serving, or actually using the Gamma for his own means.
The Gamma see humanity as nothing more than tools to be used, or as prey to be killed for pleasure. Their main goals it to bring more Gamma to the human world, as only few of them can come out of a normal Gamma Hole.
- Alien Blood: Their blood is black in color.
- Alphabetical Theme Naming: Done in katakana here. Adonis, Alicia, Argos, Adel, Alia and Alain are all pronounced beginning with the vowel sound "a", which is naturally the start of the alphabet just like in English; Eadith and Igor are read beginning with the vowel sound "i", which comes just after "a", indicating their position as high ranking officers. Javel has his vowel sound "a" as the second katakana, placing him much further down the food chain while alluding to his Elite Mook status.
- Always Chaotic Evil: The Gamma seem destructive and monstrous by nature. Justified, as they seem to be demons.
- Not Always Evil: However, at least two of their number, Gazai Gamma and Armored Gamma break this mold. Gazai by simply wanting to paint and not wanting to fight at all, and Armored by adhering to a strict code of honor and refusing to harm women or children. Igor notably refers to both of them as "defective".
- It's also downplayed, in that higher-ranking Gamma, in particular the royal family, are shown to have a great deal of positive qualities and nobler motivations.
- Anti-Villain: As it turns out, the majority of the higher-ups at least appear to have genuinely good intentions towards conquering the human world or simply following orders. Adel and Igor are still massive assholes though.
- Deal with the Devil: Their M.O., at least for the ones acting for Saionji's plans to gather Eyecons. An unsuspecting human will use one of Saionji's summoning kits to gain a source of inspiration or paranormal powers, not knowing that they become enthralled by the Gamma. The demons then will help the contractor, but they will ensure to twist the desire in ways that best suit their ultimate goals.
- Death Is Cheap: Even after a Gamma is killed, there's still a good chance they'll come back. However, if their real bodies are destroyed, they are gone for good.
- Defeat Equals Explosion: Compared to the Roidmudes last year who exploded twice when defeated (their bodies and their cores), these guys give us a triple explosion upon death: one for their Primal Bodies, one for the coats that give them power (which turns back into the item that made up their motif), and one for the Eyecons that give them life. And if a Giant Gamma is defeated, they create an explosion before returning to their normal form, meaning that a single Gamma can explode four times.
- Demonic Possession: Gammas can take possess people if they have not evolved past their Primal Body form.
- Demon of Human Origin: Their natural forms is more or less human, but have transformed themselves into demonic spirits by seperating their soul from their body.
- The Empire
- Hell: Their home world, if not actually this is close. A wasteland with a red sky that almost seems on fire.
- Hellgate: All Gamma come into the human world via a eye-shaped portal known as a "Gamma Hole".
- Immune to Bullets: Normal firearms are useless against them, as the bullets just go straight through them harmlessly. The Gamma fighting Shinnosuke mocks him for thinking a handgun would have any effect at all.
- Intangibility: They can phrase through objects no problem, though it appears to be a will-based conscious thing, since more than once has a Gamma and Ghost had trashed the environment during their fights.
- Invisibility: They can turn invisible at will, unless you're holding a Ghost Eyecon. It's not entirely clear if this is really an Invisible to Normals-based situation or simply a power, however it appears to be the former.
- Mooks: Commando Gamma.
- Mythology Gag: They have a lot in common with Shocker and it's successors.
- The default Gamma seem to be modeled after Shocker Combatmen. The titles of the Mooks is "Commandos", which was last used in Skyrider's series with the Ari Commandos.
- Gamma are rather similar to Yummies as both monsters have a base form (Primal Body for Gamma, White Yummy for Yummies) who can evolve once they are infused with an object.
- Occult Blue Eyes: The Gamma have blue eyes.
- One-Winged Angel: If a Gamma absorbs one of the Parka Ghost before Ghost can convert it into an Eyecon, they transform into a Giant Gamma.
- Our Demons Are Different: Their name literally translates to Eye Demon or Eye Devil, and they're malevolent supernatural creatures summoned via magic to serve their summoner. What's shown of their world is very similar to Hell, complete with a sky that looks like it's on fire. They also have a liking to making Faustian bargains and are capable of Demonic Possession, as well as stealing souls.
- Our Liches Are Different: They're actually an odd reverse version. Instead of their Soul Jar being their one weak point, it's their original body that is. Otherwise played straight however in that they're beings who removed their souls and put them in some sort of container to gain power. Though it's implied there may be a limit to how many times they can revive.
- Out of Continues: If forced back to their old body.
- Rule of Creepy: Much like the Zodiarts Switches, Gamma Eyecons look quite different from the Ghost Eyecons. For one, they have a hook that obviously is made to resemble severed optic nerves.
- Rule of Symbolism: Evolved Gamma have historical motifs, and at times, they have motifs that come into conflict with the motifs Kamen Rider Ghost uses.
- Soul Jar: Turns out, Eyecons are this for the Gamma. Their real bodies are kept in stasis inside capsules.
- Spell My Name with an "S": Due to the nature of the Japanese language, the literal transliteration of these guys names is Ganma, which is a preferred name in many circles despite the official materials using "Gamma". In practice, syllabic n is pronounced as "m" when used before any m syllable when spoken. So while it says Ganma, native Japanese speakers wouldn't emphasize the n and would instead pronounce it as Gamma.
- Theme Naming: The names of the members of the Gamma royal family all starts with "A".
- We Have Reserves: On a species wide scale. Any Evolved Gamma can be revived from death by simply binding a new Gamma Eyecon to the same item the first one was bound to, complete with the original's memories. Alain takes this up even further as Necrom, summoning and devouring Commando Gamma to keep his suit powered. He even overrides a Commando Gamma's identity with his own to avoid death.
Portrayed by: Yoshiyuki Morishita
A man who knows the truth about the Eyecons and has the ability to summon Gamma.
- Big Bad Duumvirate: Episode 5 reveals that he and Alain have different goals, his involving gathering the Eyecons, and are merely helping each other on their goals.
- Captain Ersatz: Very similar to Toht from Raiders of the Lost Ark, from the outfit to the quest for artifacts. Which even foreshadows his eventual fate.
- Didn't Think This Through: While he does manage to gather all 15 Eyecons, he fails to factor in the possibility that the spirits of legendary heroes won't approve of someone evil trying to make a wish.
- Or more to the point, that the very device you've been carrying around might be needed for the ritual, since it CAN make the ritual items in the first place.
- Disc-One Final Boss: Is the first of the big bads to be defeated.
- Dragged Off to Hell: Is dragged into the Monolith when the Eyecons reject him. It's unknown where he ended up, but given the last time it happened to Makoto and Kanon, it's likely nowhere nice.
- Evil Former Friend: To both Ryu Tenkuji and Kenjiro Igarashi. It's also implied that he stabbed Ryu in the back and had a role in his death.
- HeelFace Turn: Came back in Truth! The Secret of Heroes' Eyecons! where after being defeated, he realized how hard working Ryu was; Takeru then told him that deep inside him that he had the respect of his old partner and that father regarded him a hero and gave him the Da Vinci Eyecon. While Saionji refused and left, he put out the picture, stating to Ryu of how he overestimated him.
- Karmic Death: Stabbed Ryu Tenkuji in the back and had a role in Makoto and Kanon being sucked into Gamma World under an agreement between him and Igor, who wanted human samples. In the end, he's dragged into the Monolith himself when the Eyecons reject him.
- Macguffin Delivery Service: Basically lets Specter and Ghost gather most of the Eyecons for him, then snatches them right out from under their noses AND Javel's.
- The Man Behind the Monsters: He's responsible for about half the Gamma, and even the half he's not behind are on his side.
- Manipulative Bastard: Manipulates people to get the Eyecons, normally to convince them to make a Deal with the Devil with a Gamma so they'll be corrupted and sacrificed to make an Eyecon.
- Mysterious Backer: Most of the shenanigans arise from this man somehow locating the items belonging to the historical figures across the world, and smuggling them to Japan.
- Red Right Hand: He looks like a normal person... until he shows his Scary Teeth.
- Scary Teeth: He makes Steve Buscemi look adorable!
- Self-Disposing Villain: His own mistake of not having a fully functioning Ghost Driver does him in.
- Summon Magic: He can do this with the Gamma, and has the means to help other people summon a Gamma.
- Take Over the World: His wishes to gain power to control everything.
- Taking the Bullet: Shielded Kanon from Danton in Ghost RE:BIRTH: Kamen Rider Specter, resulting in his death and finally considering himself a hero to Ryu Tenkuji.
- The Unfought: Takeru doesn't even get to really meet him face-to-face before he gets sucked into the Monolith after gathering the 15 Eyecons but lacking a proper Ghost Driver to get a wish.
Alain/Kamen Rider Necrom
Portrayed by: Hayato Isomura (live), Eitoku (suit)
Youngest child of the Gamma World's ruler, he initially works alongside Saionji to obtain the 15 Ghost Eyecons and bring forth an army of Gamma with the intent of invading the human world.
With the Mega Ulorder, Alain can assume his own Rider form known as Kamen Rider Necrom.
Tropes that apply to him in general
- Ambiguously Human: He looks human, but his ability to summon Gamma under his own power and Javel (a Gamma) stating he's the son of 'the Great Ruler' who apparently dwells in the Gamma World. He is ultimately confirmed to be a Gamma in episode 12 when he turns into a Gamma Eyecon to return back to their world.
- Despite this, he has a mortal body that is no different from human as he is reminded at every other turn after being forced back into it.
- Arrogant Kung-Fu Guy: Pre-HeelFace Turn.
- Badass Normal: The guy is strong enough to fight against Specter with his bare hands without any transformation or power-up whatsoever, a rarity in the world of Kamen Rider and that's before he became Necrom.
- Bad Boss: Doesn't seem to care his arrival in the human world as Necrom sent several of his own minions flying in the process, and in order to maintain his power in Necrom form he has to eat his own minions. He also uses several of them as living shields to protect himself. He might be the Gamma Prince, but he doesn't seem to give a darn about most of them.
- That it was never proven that Gamma Commandos are more than mindless puppets doesn't make thing much better.
- Berserk Button: Takeru is this to him for some time as Alain is jealous because he thinks Takeru lured Makoto away from him. Makoto actually chose to follow Takeru of his own free will, but their attempts at explaining it to Alain just didn't get anywhere.
- Big Bad Duumvirate: Episode 5 reveals that Alain is helping Saionji on gathering the Eyecons as long as he helps Alain on whatever he is planning. With Saionji dead, he is this with Adel up until he gets framed for the Emperor's death.
- Big Eater: He once ate ten boxes of Takoyaki without even noticing until he was told. Also, he was halfway through the eleventh one when that happened.
- Black Sheep: He's a literal one, while his father, and his other three siblings all wear white. Later becomes inverted as Adel instead becomes the real Black Sheep after killing his father.
- Break the Haughty: His time in his mortal body hasn't been kind to him. Learning his Father is dead and his brother is using him as a scapegoat, getting beaten savagely by Javel and watching Makoto's Eyecon shatter in front of him. Realizing that he's afraid to die pushes this into Heroic BSoD or Villainous BSoD territory.
- Broken Bird: Gets to experience this twice. He went into a Trauma Conga Line when his father is mercilessly killed by his own brother. The second one would be when Mrs. Fumi passes away in #30. Alain takes the latter the hardest unexpectedly to the point he doubts his feelings. This eventually cemented his HeelFace Turn.Alain: If I feel this way because I have a heart, then I don't need a heart.
- Brought Down to Normal: After having his Gamma Eyecon destroyed, he is forced to return back to his human body. And while he still can use Mega Ulorder to become Necrom, he lacks most of his powers.
- Later events imply that he still has a number of those powers, but using them would be harmful if not outrightly deadly for him.
- But Now I Must Go: A few months after their battle against the Great Eyezer, he, along with Makoto and Kanon, had decided to leave the Daitenku Temple and returns to the Gamma world in their prospect to turn his home world into a utopia just like Earth.
- Cain and Abel: The Abel to Adel's Cain.
- Catchphrase: "Listen to the call of your heart!"
- The Chessmaster: His plan seems comparably complex compared to Saionji's, with most Gamma working directly for him centered around setting up the pieces.
- Death Is Such an Odd Thing: As the world of Gamma is supposed to be free of death, it confuses him a great deal. His father's death throws him into messy Heroic BSoD. Following death of Grandma Fumi left him both in pain and completely dumbfounded.
- Despair Event Horizon: After Adel kills their father for real, Alain stops responding to anything and lets himself be dragged around by Takeru. Makoto gets him out of it later on.
- Death of Gradma Fumi causes slightly less severe one to him, but still as heartbreaking and important.
- Even Bad Men Love Their Daddies: He is even acknowledged as such by Alia. He was shocked to learn that Adel framed him for killing his father, not knowing that it was Adel who started it in the first place. When Adonis is finally Killed Off for Real by Adel, this left Alain broken as a result and even forced him over the Despair Event Horizon for a while.
- Evil Laugh: He has pretty good one while charging up to his full power as Kamen Rider Necrom in #24.
- Evil Prince: At first. He ditched this role upon switching sides.
- Expy: Plays the same role as Taiga Nobori, both non human riders (Alain is a Gamma while Taiga is a Fangire) were originally antagonistic to the heroes who wants to achieve their goals for the sake of their races until they became good upon learning the error of their ways about humanity's problem.
- He is also similar to Takatora Kureshima in regards of being a white-colored rider that was initially antagonistic to the heroes before siding with the heroes in the end.
- Face Doodling: Courtesy of Onari. Paid him back, though.
- Fashionable Asymmetry: Most visible on his first outfit that has mismatched sleeves. Also, he wears only one earring.
- Fallen Princess: A rare male example. He was the prince of the Gamma World who's making a preparations for the invasion on Earth until he was thrown out by his brother Adel and then he was accused of being their father's killer.
- Good Costume Switch: An entire outfit conveniently in light green and white, passed to him by Mrs Fumi. Sadly, it also becomes a Tragic Keepsake. It even matches his color scheme as Kamen Rider Necrom.
- Grand Theft Me: If his body is ever destroyed, he can easily possess the body of another Gamma to regain it back.
- Ironically, this also happens to him when he ends up possessed by Onari when he becomes an Eyecon!
- HeelFace Turn: Not exactly by choice, but he makes one after Adel kills their father and uses Alain as the scapegoat.
- He does come around to it more after a few realizations and his father getting Killed Off for Real.
- Heroic BSoD: Gets hit with this brutally hard when his father died in his arms and then crumbled to dust.
- Heroic Willpower: Eventually used to overcome the time limit on his suit. He really gets put through the wringer in order to get there.
- Hidden Agenda Villain: While Saionji needs the Eyecons for his plans, Alain's plans are a complete mystery until late into the series.
- It's All My Fault: Tries to pin himself with the blame for getting in way of defeating Gammaizers. He does, in fact, have only limited possibilities fighting anyone on the Gammaizer level.
- Large Ham: When possesed by Onari after the latter has been turned into eyecon. Alain's own range of emotion is pretty subtle most of the time so it is tad suprising to see Hayato Isomura nail the scene.
- Laser-Guided Karma: Alain's disdain for Takeru and humans in general would become somewhat ironic after he was forced into his mortal body and teamwork with Takeru.
- Leit Motif: His battle theme is heavy, creeping electronic tune. His personal tune post FaceHeel Turn is sorrowful violin piece.
- The Load: Feels like this because his loose grip on what it means to have a mortal body (and the mortal body itself) greatly limits his fighting abilities and overal usefulness in battle. Takeru and Makoto try to convince he is not to mixed results.
- Locked Out of the Loop: His older brother has given orders to Javel not to tell Alain the truth about the Eyecons' power. Though thanks to Javel's bungling, he's started to become aware of this.
- Out of Continues: Is forced back into his original body by his brother, meaning he's mortal now.
- Psychopathic Manchild: He starts out by acting like a five years old, who was turned away by his pressumed BFF when talking to Makoto through the first half of the series. Also, his debut as Kamen Rider Necrom really gave off the vibe of a rich kid showing off a new toy. Realizing the error of the Gamma ways removed the psychopatic part, leaving him with only occassional bouts of harmless immaturity.
- Rebel Prince: His current role after he started to work alongside the heroes.
- Really 700 Years Old: When Grandma Fumi (who is 75) says that he might as well be a child compared to her, he proclaims that he has lived twice as long as she has.
- Skunk Stripe: Has a white-blond streak through his hair.
- Smug Super: Pre-HeelFace Turn. He showcases this during his first transformation into Necrom. Deconstructed when Adel dethroned their father and takes the trope from him and after becoming permanently mortal.
- The Stoic: Initially appears to be so, unless he is chatting with Makoto.
- It stops after he is forced into mortal body and the human world, where he starts to feel and express a wider range of emotion. This leads to:
- Not So Stoic: In #23, Makoto saves him from being executed by Javel, but is heavily wounded and his eyecon disintegrates. Alain sheds a tear, visibly broken by the events.
- Spell My Name with an "S": His Villain Episode has it "Alain" despite being pronounced "Aran." The former appears to be official romanized spelling.
- Summon Magic: Alain in #4 is shown to be able to open a Gamma Hole powerful enough to summon at least 8 Gamma Eyecons to serve in his plans. Also, he can summon Gamma Commandos to use as fuel of his suit.
- Took a Level in Kindness: Big time, post-HeelFace Turn.
- Trademark Favorite Food: After becoming mortal, he seems to have taken a liking to Takoyaki.
- Trauma Conga Line: AND HOW. Adel destroys his Eyecon, turning him mortal again, he gets blamed for his father's supposed murder, has seen two people literally die right in front of him and gains a fear of death because of it, and the first real human friend he gains after becoming mortal passes away due to natural causes. Needless to say, Alain's literally gone through hell after gaining the Necrom powers.
- True Companions: He gets to have this relationship with Takeru and Makoto after everything they did to each other.
- This is cruelly tested and twisted in Kamen Rider Ghost Re:birth Kamen Rider Specter V-Cinema. Challenged allegiances and heaps of trauma even set Makoto and Alain against each other, ending in Alain being mortally wounded.
- Unable to Cry: Alain cried when Makoto sacrified himself to save him, but was too shocked to do so when his father died and when came to know about the death of Gradma Fumi.
- Villain Episode: Has his own mini series, "Legend of the Hero Alain,". It details his encounters with the human world, humans and his attemps to understand everything through the series.
- What Is This Feeling?: Quotes this trope nearly word to word after becoming mortal. It takes him a moment before he realizes that he is afraid, of death in particular.
- "Well Done, Son!" Guy: Alain at least seems to feel this way, as he's rather ticked off when his father sends Javel to 'babysit' him and takes it as meaning his father doesn't trust him to operate on his own.
- Yandere: He does not take Makoto's HeelFace Turn well; besides hating Takeru for causing said turn, he almost seems obsessed with getting Makoto back on the side of the Gamma.
- You Killed Our Father: He calls Adel out for this.
Tropes exclusive to him as Kamen Rider Necrom
- Achilles' Heel: He's stronger and faster than the other Riders with more powers, but has one critical weakness: his suit can run out of power and needs to be recharged. His first fight with them ends when they simply manage to hold out until he runs out of power and Commando Gamma to absorb to recharge.
- Bare-Fisted Monk: Unlike Ghost and Specter, Necrom, especially in his base form, relies more on hand-to-hand combat.
- Cannibalism Superpower: Necrom is incredibly powerful, but his suit runs on Gamma, requiring him to absorb them to keep fighting.
- Character Tics: Just like Takeru and Makoto, Alain has his own quirk when donning a Parka Ghost. His is gripping the right side and lightly tugging it to adjust it.
- Combat Tentacles: In Grimm Damashii, in addition to being able to be used as daggers, the pen nib-like edges on his shoulders can extend on green tendrils and be used as this.
- The Corrupter: He can seemingly brainwash Eyecons and his Necrom Eyecon itself can control a Ghost Driver-user. Poor Grimm and Specter...
- Cyclops: The faceplate in Necrom's base form has a giant eye on it, which is visible through the visor in all of his forms.
- Demonic Possession: His corruptive powers seem to stem from this as a base. He can even possess his own kind to either move out of the way of attacks or command them to fight, which seems to make them stronger.
- Elemental Shapeshifter: Can shift into a liquid form which allow attacks to harmlessly pass through him.
- Evil Counterpart: To Kamen Riders Ghost and Specter, giving that his suit is white to the heroes' black.
- Right down to the transformation sound riffs. Ghost and Specters are fast rap sounding, while Necroms are shorter, more rock based riffs.
- Evil Knockoff: Seems to be this, seeming to be more like Powered Armor than the other two's Rider forms (which seem to be more of a physical transformation) and having a much more artificial look to him. Even his Eyecon seems completely different than any other type. It also needs to be actively powered and recharged to maintain transformation.
- Fantasy Metals: His suit is composed of 'Quantum Metal', which permits him to phase through attacks.
- Finishing Move:
- Omega Load: The Necrom Eyecon announces "Destroy!" as Necrom charges demonic energy into himself, which he can channel as a Rider Kick, Rider Punch or a blast of energy from his palms. Upgrades into Playing with Fire after absorbing some energy from Gammaizer Fire.
- Omega Finish: Using the Gan Gun Catcher with an Eyecon slotted in it, Necrom can fire an energy blast at his foe depending on which Damashii he's using at the time.
- Omega Ulord: Necrom summons the spirits of Sun Wukong, Zhu Bajie and Sha Wujing, who then transform into a cloud that Necrom can ride on for a quick getaway. Once he gains Sanzo's friendship and loyalty, however, the spirits instead attack Necrom's enemy while Necrom rushes in for the final blow.
- Gamma Resource: Necrom's Parka Ghost needs to be recharged or his transformation will be dropped. How does he recharge? Summon some Gamma and absorb them.
- Hour of Power: The Necrom powers seem to run on a time limit which Alain needs to feed or they'll fade and cancel his transformation.
- Intangibility: He has the ability to make himself intangible towards his opponent's attacks. According to official materials, this is a property of the material his suit is made of.
- Irony: His transformation call is 'Crush the Invader'. Necrom is the extradimensional invader.
- Necessary Drawback: Has a lot of sheer power with a Superpower Lottery, but unlike the other two, more limited Riders, he has a finite energy supply and will run out of power if he doesn't recharge. The more damage he takes and the more power he uses seems to speed this up.
- The Necromancer: Befitting his name, he can directly control hoards of Gamma Commandoes, and is able to brainwash the Heroic Eyecons.
- Reality Ensues: Being pretty much completely artificial and Alain defecting from the Gamma and cutting him off from any upgrades means he isn't growing as effectively as the purely supernatural Riders are.
- Superpower Lottery: Stronger than the Driver-based Ghosts, can command Gamma and Eyecons alike, and has a wide powerset that neither Ghost nor Specter possess.
- Can't Catch Up: However, Necrom eventually starts lagging behind Ghost and Specter because of its lack of an equivalent to the Mugen and Deep Specter Eyecons. Earning the loyalty and friendship of his partner Eyecons and the acquisition of the Gan Gun Catcher alleviates this somewhat. This even extends to his upgrade Yujou Burst. It only upgrades him to about mid-season powerup levels while in the same V-Cinema Makoto reaches Mugen levels of power.
- Taking You with Me: Apparently, his ultimate attack is this by putting all his energy into one self destructive attack. He's tried this on two occasions but never got to do it either time. Justified, as Alain is a Gamma and thus he can just respawn if this happens. Until he was returned to his real body.
- Weapon of Choice: The Gan Gun Catcher, which is a retooled and recolored Gan Gun Hand.
Portrayed by: Akihiro Mayama
Alain's older brother. He desires the Ghost Eyecons as well to enact his own desires...
- 0% Approval Rating: In episode 41, Makoto outright states that Adel's insufferable god-like delusions made him despised by everyone else.Makoto: Who are you creating a perfect world for? There is no one around you anymore!
- A God Am I: Once he's granted the power of the Gammaizer, he considers himself to be the "perfect existence" and the one who will guide the world. Becoming Perfect Gammaizer, as well as being able to connect with the Great Eye, just make his conviction of this even stronger.
- Alas, Poor Villain: Adel might be a Smug Super Narcissistic emperor, he eventually realizes the error of his actions. Moments before Adel could reform, the Gammaizers took over him, forcing Takeru to kill him to free him the Gammaizers' control. It ends with a saddening goodbye to his siblings as Adel's spirit ascends in the afterlife.
- Authority Equals Asskicking: He's Gamma royalty and is strong enough to take on Toucon Boost Ghost and Specter at the same time without breaking a sweat. Even Tutankhamun's Omega Fang barely slow him down. As Perfect Gammaizer, he's pretty much as strong as Mugen Damashii.
- Badass Longcoat: Sports a black one since his debut episode. He takes it off by episode 43.
- Big Bad: For the majority of the show, although it gradually becomes clear the Gammaizers are the ones pulling the strings.
- Black Sheep: Oh, good Lord, he fits this trope to a tee than Alain. It sees that in his eyes his father became so neglectful to him.
- Cain and Abel: The Cain to Alain's Abel.
- Combat Tentacles: One of Perfect Gammaizer's powers.
- Despotism Justifies the Means: He's a megalomaniac who is obsessed with power and he will do anything in order fulfill his invasion on the human world and reshape it in the same vein as the Gamma world.
- Drunk with Power: After becoming the Perfect Gammaizer he started slipping into this, and giving less of a care what happens to his own family.
- Easily Forgiven: Even after all the crap he's pulled, Takeru forgives Adel mostly on the merit that he's still Alain's brother.
- The Emperor: After killing his father, he is now the new Emperor of the Gamma World.
- Even Bad Men Love Their Mamas: See Used to Be a Sweet Kid below.
- Evil Counterpart: To Alain as a character, and as Perfect Gammaizer he has virtually the exact same abilities and fighting style as Mugen Damashii.
- Eviler Than Thou: To Alain. Alain is dangerous and villainous, but Adel is clearly much worse than him.
- Evil Prince: Killed his own father and frames his younger brother for it.
- Freudian Excuse: It's been implied that his mother's passing when he was young had a profoundly negative effect on him.
- Hidden Agenda Villain: He wants the Ghost Eyecons, and is willing to deceive his brother to get them, but why is unknown. Turns out he's planning to overthrow his father and rule over both human and Gamma worlds.
- I Am the Noun: "I am the world itself!"
- It's All About Me: Somewhat literally, as his master plan is to turn everyone into duplicates of himself.
- Jacob Marley Warning: Gives one to Alain as his Last Words before departing for the afterlife."Don't make the same mistakes I did."
- Light Is Not Good: His Gamma Ultima form is almost completely white.
- My God, What Have I Done?: Takeru manages to break through Adel's defenses in Episode 48 and, along with an assist from Alia, shows Adel the error of his ways. It doesn't last long before the Gammaizers forcibly assimilate him, leaving Takeru with no choice but to kill him.
- Narcissist: Sees himself as the only one who can fulfill his father's ambitions in a distorted way.
- Never My Fault: His attitude and irrationality pretty much ensures that he'll never admit that these precise traits have brought about chaos rather than the perfection he seeks.
- Nice Job Fixing It, Villain!: Framing Alain for their father's death and forcing him into his mortal body eventually led him to join the side of humans and help them stop Adel.
- One-Winged Angel: Perfect Gammaizer.
- The Perfectionist: An incredibly dark example. He craves perfection, both in himself and in the world, and he doesn't care what he has to destroy or sacrifice to get there.
- Sanity Slippage: Considers everyone as inferior and isn't above killing his own family members.
- Self-Made Orphan: Killed his own father once he considered his existence to no longer be necessary.
- Sibling Rivalry: Given Alain's behavior, and the fact Adel ordered Javel not to tell Alain about the Eyecon's true power and instead gather them for him, it seems the two have this going on.
- Smug Super: A villainous example. He begins to showcase this upon ascending to the throne and introduced to the power of the Gammaizers, those he deemed imperfect are considered beneath him. It also doubles as his Fatal Flaw.
- The Sociopath: He was confirmed as this the moment he told Magistrate Eadith that the extinction of the Gamma was "of no concern".
- The Starscream: He kills his father and usurps the throne.
- The Stoic: Even worse than Alain, he hardly ever changes his expressions, even when killing his own father.
- The Unfettered: He doesn't even care if he kills his own family in his mad quest for perfection.
- Used to Be a Sweet Kid: Alia states in Episode 45 that he used to be kind and loving to his family, even idolizing his father. Then their mother died.
- The Usurper: His ultimate goal: to overthrow his father and become emperor. He succeeds.
- Villainous Breakdown:
- He verges into this each time whenever a Gammaizer is destroyed.
- Has this in episode #45 when Takeru inadvertently entered on his memories.
- Then in #48 again as Takeru fully connects to Adel's heart, it was only a matter of time he dropped into his knees, realizing his mistakes.
- Walking Armory: Like Mugen Damashii, Perfect Gammaizer's fighting style rapidly switches between using different weapons, in his case the various weapon-type Gammaizers.
- "Well Done, Son!" Guy: His Start of Darkness, also doubles as a deconstruction. Due to his mother's death and his disappointment toward his father. His dad actually lack of appreciating toward himself.
- With Great Power Comes Great Insanity: Look at his attitude and Sanity Slippage throughout the series.
Alia/Kamen Rider Dark Necrom P
Portrayed by: Reon Kadena
Alain and Adel's older sister. She seems to be the one who took the Fukami siblings under her care when they were stranded in the the Gamma world. She eventually becomes Kamen Rider Necrom Pink.
- Disposable Woman: Averted as a whole but played straight with her rider form. While she is defeated in her only fight as Dark Necrom P, she survived the story; making her the first female Rider since Mayu to survive the stories of her series.
- Nice Girl: She is shown to be a kind person unlike her brothers. She takes care of the Fukami siblings and misses them a lot when they left the Gamma World.
- Overshadowed by Awesome: Being a fairly strong and skilled fighter is nice and all, but it means very little when you're fighting against the equivalent of gods.
- Reasonable Authority Figure: She's understandably skeptical of Adel's claim that Alain killed their father, as she knows just how much Alain respected their father.
- Strong Family Resemblance: As an adult, she is identical to her mother.
Portrayed by: Sotaro Yasuda (live), Shinsuke Kusano (suit)
A human-looking Gamma who can use a special Eyecon to transform into the stronger Superior Gamma. He was sent by Alain's father, Emperor Adonis, to Earth to aid his son in their plans.
- Badass in a Nice Suit: Dresses up like a noble and can easily go against both Ghost and Specter at the same time. Though only when they're not actively working together against him, though even then he's a challenge to them.
- Back from the Dead: First time in episode 15, courtesy of Alain. However, as revealed in 22, only his Eyecon got destroyed during both of his deaths, as his real body is completely fine, as Adel gives him another Eyecon to transfer his soul to.
- Because You Were Nice to Me: Part of his HeelFace Turn is due to Onari treating him with kindness.
- Blood Knight: While he didn't seem like it, episode 15 makes him seem like this, as he spends most of his fights either being disappointed in Specter due of how weak he is now or asking Ghost to put more power to his strikes. Even when he is on the receiving end of a Rider Kick from Specter, he is saying how this is the hatred what makes him feel alive.
- Cyclops: If you look at Superior Gamma's visor close enough, you notice that it has same eye pattern that Eyecons have.
- Came Back Strong: After his second defeat he was given a much stronger "Ultima" Gamma Eyecon that let him assume a similar form to Adel's Gamma form. He was able to Curb stomp Necrom and Specter with it. He loses it and goes back to his Gamma Superior Eyecon after being beaten by Takeru's Grateful Soul.
- Foreshadowing: Mentions Alain's father the "Great Ruler" in his debut episode. And also reveals in Episode 10 that Alain has an older brother who is presumably more powerful given that he could order Javel to lock Alain out of the loop as to the power of the Eyecons.
- HeelFace Turn
- Horned Humanoid: The Superior Gamma suit has a single straight horn in the head.
- I Choose to Stay: Decides to stay in the human world after being resurrected.
- Midseason Upgrade: Surprising for a villain, but is promoted from Gamma Superior to Gamma Ultima.
- Named After Somebody Famous: His name comes from Inspector Javert, the main antagonist of Victor Hugo's Les Misérables.
- One-Winged Angel: When he returns, he fuses with a Gundari to become a superpowered version of it.
- Praetorian Guard: While most Gamma Superior seem to be Elite Mooks, if not Mook Lieutenants, he himself serves the royal family above the others.
- Redemption Equals Death: Gives up his life to prevent Alain from doing a suicide attack on Great Eyezer. Thankfully, he is resurrected thanks to Takeru.
- So Proud of You: After sacrficing himself for Alain, he says he's proud of how much his master has grown.
- Trademark Favorite Food: After returning to his real body and being stuck in the human world, he become very fond of Onigiri just as much as Alain likes Takoyaki.
- Villainous Breakdown: Goes berserk when his failures make Alain disappointed in him. It gets him killed when he goes off to face the Riders all on his own.
- Walking Wasteland: His Ultima form grants him this power, causing anything he touches for long enough to decay.
- The Worf Effect: The first time he really fights he is represented as someone who is able to take on both Ghost and Specter at the same time, only to almost die to them when they start working together. And in the next episode, he dies in a Curb-Stomp Battle after Takeru acquires Toucon Boost. And then he returns to demonstrate his ability to fuse with Gundari, he ends up dying again, this time to Specter Houdini Damashii. It happens again when he returns with his Ultima form, only to get utterly curbstomped by Grateful. Seems the poor guy's fate is to keep playing the Jobber to new forms.
- Episode 28 shows he's painfully aware of this, and it's sent him into a depression.
Portrayed by: Hiroshi Yamamoto
Another Superior Gamma like Javel, this one working as a scientist. He possesses a prototype version of the Mega Ulorder, what can use Gamma Eyecons to empower his Superior Gamma form further. He is Adel's subordinate and only obeys his order and not Alain's.
- Armor-Piercing Slap: He's been on the receiving end of several from Akari. They left quite an impression on him as merely seeing her has turned into a minor Berserk Button of his.
- Bad Boss: Oh man is he.
- Break the Haughty: See Armor-Piercing Slap above.
- Butt-Monkey: While he might have his intimidating moment, at his core he's this due to being greatly outclassed by the time he starts getting more involved in fights even with his incredibly varied transformation set, often getting casually tossed out of the way. It's telling that the first time he actually won a one on one fight decisively was against Onari.
- Dirty Coward: He perfectly has shades of this.
- The Dragon: To Adel.
- Evil Counterpart: To Akari. Both of them believe deeply in science, but his ideals as a Gamma greatly contrasts with Akari. Hilariously enough, them being each other's counterparts leads him meeting his intellectual match and rival in Akari herself, which eventually blossoms into, of all things, love.
- Evil Genius: He is a man of science (or scotopography, as it is called in the World of Gamma) and not a really pleasant person.
- Evil Knockoff: His device is this to Ghost Driver, as it uses Gamma Eyecons to achieve same effect.
- The Evils of Free Will: His speech to Akari in #17 can be summarised as the only way for a perfect utopia is for lack of any variables, and individuality what humans possess for example just creates more and more of them.
- Expy: Cast in the same mold as Brain for being an Evil Genius with Butt-Monkey traits of their respective groups.
- HeelFace Turn: Has one after being revived by Takeru's wish.
- In-Series Nickname: Akari calls him "KMS": Kanpeki-narunote Mad Scientist.
- In the Hood: He has a parka in his Superior Gamma form, and can create ones based on previous Gamma with his device to empower him further.
- Jerkass: Good Lord is he. It shows the most during Episode #28 where the Onpu Gamma composes several famous orchestral pieces from history for him and he declares each and every one to be trash causing Onpu to have a Freak Out and flee.
- Laughably Evil: He becomes this after receiving many receiving ends of bitch-slaps from Akari.
- Mad Scientist: In contrast with Akari's Science Heroine, she outright calls him this.
- Manipulative Bastard
- Monster of the Week: Due to his Transformation Trinket, he's basically a one man version of this.
- Mythology Gag: His use of Gamma Eyecons is similar to how Chaser used Roidmude Viral Cores, except these are complete transformations rather than weapon mode changes.
- The Perfectionist: Quite frankly, most of his plans are actually legitimately brilliant and would likely work... if he ever decided to give his subordinates the tiniest bit of leeway whenever a hitch comes up. He doesn't, so much whining and freaking out tend to happen instead.
- Smug Smiler
- Smug Snake: Of all people, he has much ego for someone as genius as him.
- Taking the Bullet: For Akari of all people in episode 48.
- Too Kinky to Torture: In the Specter V-Cinema, he actually seems upset when Akari doesn't slap him and reacts with glee when she does.
- Ugly Guy, Hot Wife: He marries Akari in the tie-in novel Memories of the Future, making them this trope.
- Your Soul is Mine!: He carries a device around his neck that can be used to gather up souls, and then release them to be used as his puppets.
Portrayed by: Hiroshi Katsuno
Emperor of the Gamma and father of Alain, Adel and Alia. Sent Javel to assist Alain.
- The Emperor
- Good Parents: Love his children and wants the best for them.
- Greater-Scope Villain: Is the ruler of the Gamma, but remains in the Gamma World with Alain being The Heavy and primary villain.
- Killed Off for Real: His real body is killed by Adel in #27.
- Meaningful Name: Adonis is the name of the Greek God of vegetation.
- Orcus on His Throne: Is the true ruler of the Gamma, but mainly acts through his son Alain and his minion Javel. Possibly justified, as Javel implies high ranking Gamma require the boundary between their worlds to degrade for them to be able to come through.
- Well-Intentioned Extremist: He truly believes that the Gamma World is a perfect utopia compared to the human world, and believes that humans will keep on fighting each other if they have free will.
- Alia reveals more of his motivations in episode 39, namely that His wife passed away and his other son, Argos, succumbed to illness soon after. This caused Adonis to fall into despair and attempt to create a Utopia. He also never aimed to invade the human world.
Portrayed by: Thane Camus
The president of the Deep Connect company. While outwardly an ally to the Paranormal Investigation Labs, he is actually Gamma-possessed and under Igor's control so that his company can be used as a front for the Gamma's Demia Project.
- Consummate Liar: Igor enforces this on Bills as a diversion from Takeru and the gang, they didn't realize this until episode #44.Igor: Bills is my minion. I've been watching him fool you and laughing in the shadows!
- Meaningful Name: Based on Steve Jobs and Bill Gates.
- The Mole: When Takeru and friends infiltrated Deep Connect in #29, Igor had him roughed up a bit to make him look like he wasn't involved in the Gamma's plans and thereby earn the Riders' trust.
- Reasonable Authority Figure: He acts like one, and probably would be without Igor influencing him.
- What Happened to the Mouse?: As he and the others try to escape Adel's influence in episode 46, Bills ended up being affected and had his head changed to Adel, prompting the others to scream and run; Bills was not seen again at all from that point on, though it was presumed that he and all others affected by the Demia Project were restored back to normal.
Portrayed by: Seiji Takaiwa
Alain's former instructor. Considered by Igor to be Javel's replacement.
- Asskicking Equals Authority: He's an Ultima Gamma. It goes without saying that he qualifies.
- Killed Off for Real: He was permanently killed off by Danton during the events of Ghost RE:BIRTH: Kamen Rider Specter gaiden movie.
- Made of Iron: Took several Omega Drives without dying. It took Mega Omega Formation, which is 16 consecutive Rider Kicks to put him down.
- Proud Warrior Race Guy: To the point where he got pissed when Takeru refused to use Mugen to fight him, considering it an insult.
- Time Master: In his first fight with the Kamen Riders, he rewinds time to protect himself from the Riders' Triple Rider Kick, thus forcing them to retreat.
Portrayed by: Ryosuke Yamamoto (live), Yohei Fujita (suit actor)
A clone of Makoto Fukami sent by Adel that transforms into Kamen Rider Specter. To distinguish himself from the real one, he wears the Gamma's military uniform as opposed to the real Makoto wearing leather. It was later revealed that doppelgängers were a side effect of Makoto's usage of the Deep Specter Eyecon. The Eyecon draws power from the Gammaizers to give it incredible strength, hence the Gammaizers created the doppelgängers as a counter to this. Specter's V-Cinema retcons this into the 15 Makoto Doppelgangers being incomplete prototypes of Makoto that were stolen from Danton.
- Ax-Crazy: One of the obvious traits to distinguish himself from the real Makoto, most especially the crazy eyes.
- Becoming the Mask: Episode 47 shows that he's starting to become more and more like Makoto, to the point where he confuses himself by considering Takeru his friend. It turns into a full on HeelFace Turn in episode 48 when he starts fighting alongside the real Makoto in earnest and later pulls a Heroic Sacrifice to save the original's life.
- Cloning Blues: The remaining Clones that Makoto destroys seem pretty happy to be dead at least. Danton isn't a particularly great father after all.
- Enemy Mine: Does this with the real Makoto in episode 48.
- Expy: Possibly of Souji Tendou's own doppelganger and Kamen Rider Ryuga.
- Even Evil Has Standards: Of a sort. He might be an amoral and cruel clone of Makoto, but He's still a clone of Makoto and so can't bring himself to snap Kanon's neck when he has a perfect chance even though he's been ordered to.
- Evil Twin: Of Makoto. This trope is taken literally when the doppelganger starts wearing the real Makoto's leather jacket to further fool his friends.
- Psychotic Smirk
- Synchronization: Each time Makoto defeats his doppelganger, he experiences seizure-induced pain.
Tropes exclusive to him as Kamen Rider Specter
- Mirror Match: Since he uses the Specter Eyecon, this leads the real Makoto into relying into the Deep Specter Eyecon. This trope becomes even more literal when the doppelganger gets his own Deep Specter Eyecon.
- Willfully Weak: The Specter doppelganger intentionally allows himself to be curbstomped by the real Makoto to make him feel pain.
Portrayed by: Reon Kadena
The wife of Adonis and mother of Argos, Alia, Adel, and Alain. Her death from an illness drove Adonis to create the Gamma World.
Gammaizers/The Great Eyezer
Portrayed by: Akihiro Mayama (live, voice from episode 35 onwards), Sayaka Ohara (voice until episode 34)
The 15 "Protector Gods" of the Gamma world, their job is to protect the Gamma world from outside threats. They materialize from the 15 monoliths in the Gamma Emperor's prayer room.
- Beware the Silly Ones: Gammaizer Climate, who usually carries a silly-looking blue bird with cloud for wings that looks like Swablu, is actually the very Gammaizer that guided Adel into becoming Perfect Gammaizer, the one that helped other Gammaizers in developing sentience and emotion. The birds may look silly, but when used in attack, they hit as hard as other Gammaizer's attacks.
- BFG: Gammaizer Rifle's true form.
- BFS: Gammaizer Blade's true form, which can even split into two for Dual Wielding.
- Blade on a Stick: Gammaizer Spear's true form.
- Blow You Away: Gammaizer Wind is the fourth one.
- Demonic Possession: Late in the show, several of them possess previous victims of the week as part of their study of human emotions.
- Dishing Out Dirt: Gammaizer Planet.
- Drop the Hammer: Gammaizer Hammer's true form.
- Eldritch Abomination: The Great Eyezer's gigantic form. Monstrous in form and can easily erase a human being's body and soul.
- Evil Counterpart: To the 15 Heroes.
- Expy: Being the evil counterpart of 15 heroes and The Great Eye, this would makes them expy of Corrupted Holy Grail. Bonus points that they are also voiced by Sayaka Ohara. Even more after becoming The Great Eyezer, as they become one with the The Great Eye itself minus it's benevolence.
- Fusion Dance: Turns out they can merge together in the power booster version of this trope. They can also merge with the Great Eye to create the Great Eyezer.
- Gravity Master: Gammaizer Gravity is the second one.
- Hoist by His Own Petard: By the end of the show, Takeru and crew still have no way to permanently defeat the Gammaizers, who've learned how to revive each other even when killed by Mugen. They proceed to merge into a One-Winged Angel form that, while much more powerful, can't revive anymore and thus is quickly slain. The irony comes in that in their initial appearances, they frequently turned Takeru's own All Your Powers Combined form against him in similar fashion.
- Impressive Pyrotechnics: Great Eyezer has quite possibly the biggest, fieriest death explosion of any toku villain ever.
- Magnetism Manipulation: Gammaizer Magnetic's ability via Gammaizer Magnetic Blade.
- Make Me Wanna Shout: Gammaizer Oscillation.
- Making a Splash: Gammaizer Liquid is the third one fought by Takeru and co.
- The Man Behind the Man: Takeru's friends realize that the real threat to the world is the Gammaizers and not Adel (who has been manipulated by the Gammaizers all along), which is made worse when they merge with the Great Eye.
- Me's a Crowd: Their human form are modeled after Adel. Yes, ALL of them. Their voice is that of a woman at first, until switching to Adel's voice, then briefly to several individual voices of people they've possessed, and finally back to the woman's voice.
- Nonstandard Character Design: Gammaizer Magnetic Blade, a rare non-humanoid tokusatsu monster that's not CG or a puppet, but two people in a suit.
- Palette Swap: The Great Eyezer is a gold color repaint of Kamen Rider Extremer.
- Physical God: They are the protector gods of the Gamma world and the backbone of the world's existence. They are strong enough to stop the summoning of The Great Eye when Takeru tried to do it for the second time, by sending a huge energy blast towards the monolith in the Dai-Tenkuji temple. After absorbing the The Great Eye and becoming the Great Eyezer, they become even more omnipotent, even able to turn night into day easily.
- Playing with Fire: The first Gammaizer that Takeru and co. face is the Gammaizer Fire.
- Resurrective Immortality: If killed, they simply regenerate back in the prayer room in their monolith forms. In fact, the reason why they consider Takeru to be such a great threat is because his Mugen Damashii form is thus far the only thing that can permanently take them out of action.
- Shock and Awe: Gammaizer Electric.
- The Straight and Arrow Path: Gammaizer Arrow's true form.
- Weather Manipulation: Gammaizer Climate.
Portrayed by: Takahiro Fujiwara (voice), Yugo Fujii (suit)
A Gamma that was summoned and empowered alongside the Gamma that would become Yari. With Yari, Katana wreaked havoc on the city in search of the Eyecons until he met our hero... and killed him. Thankfully, he soon came back to fight back. After Yari's death, Katana was next, and goaded Ghost to follow him. After some Bike-Fu, Katana summons some Gamma Commandos to tire out Ghost, only for Ghost to find the Musashi Ghost and Musashi Eyecon.
- Blade Below the Shoulder: His right arm is a giant, wide sword.
- Came Back Strong: Is much more powerful after resurrecting, with new powers and able to keep up with Takeru's Mid-Season Upgrade.
- Hero Killer: This is the guy who kicked of the story. Not bad for a Monster of the Week.
- Karmic Death: Katana's death personifies the phrase "Live by the Sword, Die By the Sword". He kills Takeru with his sword arm, and gets killed by Musashi Damashii.
- Killed Off for Real: Meets his karmic end with Ghost Musashi Damashii's Omega Slash with the Gan Gun Saber in Twin Sword Style Mode. Subverted when he comes back in episode 13, where he's killed again by Goemon Damashii with the Sunglasseslasher's Mega Omega Shine.
- Nice Job Fixing It, Villain!: Congrats on creating the very thing that continually kills off your kind on a weekly basis, Katana Gamma.
- Rule of Symbolism: Katana is based on Sasaki Kojiro, who had died fighting Miyamoto Musashi. Fitting how it was Musashii Damashi that ended Katana at first.
Portrayed by: Kosuke Takaguchi (voice), Eitoku (suit)
A Gamma that was summoned and empowered alongside the Gamma that would become Katana. With Katana, Yari wreaked havoc on the city in search of the Eyecons until they meet our hero... and Katana killed him. Thankfully, he soon came back to fight back, which ends up getting Yari killed.
- Blade on a Stick: Natch.
- Blood Knight: Yari is very confrontational, especially compared to his partner, Katana.
- Impaled with Extreme Prejudice: Akari barely avoided this fate thanks to Takeru when Yari tries to take a stab at her.
- Fearless Fool: Charged head-on towards Ghost when Ghost was charging up his finisher.
- Killed Off for Real: Is killed by Ghost Ore Damashii's Omega Drive Rider Kick.
- Rule of Symbolism: Yari is based on Houzouin In'ei, a Buddhist monk that developed the Houzouin-ryu style of spear combat that revolve around the jumonji yari, which is also the type of spearhead that Yari was empowered with.

- Telescoping Staff: Showed that Yari's yari can extend its length once.
- Would Hurt a Child: Hurls a Pirate Ship ride full of children into a observation tower without a second thought.
Portrayed by: You Kitazawa (voice), Jun Watanabe (suit)
A Gamma who was summoned courtesy to Dr. Sonoda who uses the doctor to turn his idea of a teleportation device to a device what would create a giant Gamma Hole. While successful on creating the device and almost opening it after fusing with Edison Parka Ghost, his plan was stopped by Takeru and was killed off when he acquired Edison Damshii.
- Attack of the 50-Foot Whatever: Became the first Gamma to become a Giant Gamma by absorbing the Edison Ghost when it was freed from its sealed state.
- Hoist by His Own Petard: Denki played a contributing role in his own death, where he was shooting electricity at Ghost Edison Damashii. Turns out, Edison Damashii can absorb and redirect electricity.
- Killed Off for Real: Was blasted away by Ghost Edison Damashii's Omega Shoot with the Gan Gun Saber in Gun Mode.
- The Muse: Sonoda intended to use the Gamma in this manner, but it was turned against him.
- Reality Ensues: Don't bring swords to a fight with a electricity-shooting monster.
- Rule of Symbolism: Due to fighting against Edison Damashii and its head resembling a Tesla coil, it hearkens back to the "War of the Currents", where Thomas Edison and Nikola Tesla campaigned against each other over the use of direct electrical current and alternate electrical current.
- His Giant form looks an awful lot like a battleship. It might be a reference to the Philadelphia Experiment, an alleged military experiment that happened on U.S. Navy destroyer escort USS Eldridge (DE-173). In said story, the ship was claimed to be invisible/cloaked from any opposing battleships.
- Shock and Awe: Par for the course.
- Wall Jump: His Giant form can cling into walls and scale up them by jumping up them.
Portrayed by: Takuya Kirimoto (voice), Yugo Fujii (suit)
A Gamma who was summoned to help out Mari Shirase in her Robin Hood-like crime spree as Little John. His true objective, however, was to corrupt her so that her soul would turn into an Eyecon in order to gain the Robin Hood Eyecon. His plan was foiled when Takeru broke Mari out of his influence and then used Robin Hood Eyecon to take him down.
- An Axe to Grind: As his name suggests, though he specializes on throwing valleys of axes at his foes instead of just fighting up close. He also has a giant axe sticking out of his chest.
- Barbarian Longhair: His hair is long, messy and red to boot.
- Deflector Shields: Can create a red mist-like shield front of him to stop any projectiles from reaching him. However, this applies to his own axes as well, and needs to create gaps in shield for them to reach anywhere.
- Killed Off for Real: Gets shot down swiftly by Ghost Robin Hood Damashii's Omega Strike with the Gan Gun Saber in Arrow Mode.
- Rule of Symbolism: Ono is based on Juraj Jánoík, a Slavic folk hero, who was really similar to Robin Hood, as both of them stole from the rich and gave the loot to the poor.
Portrayed by: Kiyohito Yoshikai (voice), Jiro Uchikawa (suit)
A Gamma who assisted a Primal Body Gamma who was possessing Sakuma Risa in an attempt to gain the Nobunaga Eyecon, with his role being to spread his clones across different places to eventually raise a part of a city into the skies to create "Azuchi Castle" to Hashiba Nobuyoshi to further his corruption. They were almost successful before Ghost arrived and was able to defeat Book Gamma.

- Mind over Matter: He has some sort of telekinetic powers. Where he normally can only cause small objects to levitate, entire army of clones in certain locations allow them to lift an entire city-block into the skies.
- Nice Hat: A top hat. The real Book Gamma even has a dodo bird on top of the top hat, who itself also wears a top hat.
- Rule of Symbolism: His base design is an Alice Allusion, suggesting he was based on Lewis Carroll, the book's author and a famous mathematician and logician.
Machine Gun Gamma
Portrayed by: Katsumi Chō (voice), Daisuke Satō (suit)
A Gamma who alongside his "famiglia" was send into an elementary school for an unknown plan, with him making sure no one gets into the school. His plan manages to be successful, but only after Ghost defeats some of his companions, after which Specters drops in and finishes the job.

- A Father to His Men: A villainous example towards is "famiglia". He gets pissed when Ghost kills a few of the Commando Gamma under his command.

- Back from the Dead: Briefly comes back in episode 24 alongside Seiryuto Gamma in order to kill Alain, but neither of them last that long.

- Too Dumb to Live: If he just didn't shoot Specter in the back, the rider would've taken care of Ghost and the problem would have resolved itself. Way to go.

A Gamma what was summoned courtesy of Kousuke Kimijima, whom he helped on composing his next masterpiece. However, his true plan was to make him connect with Beethoven so that he can then make Kousuke kill himself and such create the Beethoven Eyecon. His plan was foiled when Takeru broke his influence over Kousuke and summoned the Beethoven Parka Ghost, eventually leading his defeat.
He comes back in Episode 27 by Igor's will in order to create a composition to the launch event for Demia Project. However, he soon finds out that Igor isn't particularly interested in classical music at all...
- HeelFace Turn: Changed sides in Episode 27, partially due to his new friendship with Cubi, partially because Igor was absolutely horrible to him.
- Killed Off for Real: Gets finished off by Ghost Musashi Damashii's Omega Slash with the Gan Gun Saber in Twin Sword Style Mode followed up by Musashi's Omega Drive.
- Not So Different: His reappearance in Episode 27 shows that he and Cubi have a lot in common. Both are dedicated to their craft and both had recently hit a slump. Though Cubi's was from artist's block and Onpu's was due to depression over Igor's verbal abuse.

While she provided to be one of the most persistent Gamma what Ghost has faced, he was able to break the people out of her control and defeat her once and for all.
- All Webbed Up: Takeru's method of countering her swarm ability? Using the Spider Lantern to create a giant web, snagging her like a giant sticky fly trap.
- Big Creepy-Crawlies: If a humanoid wasp wasn't large enough, her Giant form is a giant queen bee on top of a bulldozer.
- Flight: She is capable of flying even without any actual wings.
- High-Class Glass: Wears a really large monocle. Which seems to come with the fact that the object she was fused with was a magnifying glass.
- Killed Off for Real: Is blown away by Ghost Billy the Kid Damashii's Omega Impact with the added assistance of the Spider Lantern.
- Nice Hat: A bright pink cowboy hat which is just there to tie in to the cowboy thing, apparently.
- Not Quite Dead: She escapes death not once, but twice. The first time she avoid Takeru's Omega Impact by sending a portion of her swarm to take the attack for her, and the second time she survives the destruction of her Giant Gamma form by evacuating her main body from it before Takeru destroys it. It takes Takeru discovering her main body and destroying it to make her death stick.
- One to Million to One: She has the power to transform into a huge swarm of wasps.
- Puppeteer Parasite: She can use her own wasps to take control of a huge group of people at once.
- Tertiary Sexual Characteristics: Justified as all the evolved Gamma are armor pieces and accessories added to the same base Gamma suit.

A Gamma summoned by Saionji for the purpose of creating the last remaining Eyecon needed for his plan, after which he is ordered to get the Eyecons what Takeru and Makoto had in their hands.

- Rule of Symbolism: Due of him being based on the Green Dragon Crescent Blade, he is by extension based on Guan Yu, due of the said weapon being the one he uses in Romance of the Three Kingdoms. The relation with Benkei might come with the fact that Benkei and Guan Yu were both people who had undying loyalty towards their masters.
Portrayed by: Yuma Uchida (voice), Eitoku (suit)

Gazai note Gamma/Cubi-chan
Potrayed by: Taiki Matsuno (voice), Jiro Uchikawa (suit)

Katchu note Gamma
Portrayed by: Naoko Kouda (voice), Minoru WatanabeAs his project is advancing, Igor summons a sword-wielding Gamma to take care of Ghost and Specter in order to gain their Eyecons. However, she is less effective than he hopes for, due of her code of chivalry conflicting on just finishing the job.

- Large Ham: The younger brother's an eccentric one, often posing as if he is an airplane.
- Mad Bomber: While the younger one can shoot with his fingers, the older one goes for more devastating attacks using explosives and missiles.

Gigantic serpent-like creatures from the same world as the Gamma that serve them.
