This is a partial character sheet for Kamen Rider Gotchard. Subjective trope and audience reactions should go on the YMMV page.
The monsters of Kamen Rider Gotchard, created from fusing a Chemy with a human that harbors extreme malice.
open/close all folders
In General
- Defeat Equals Explosion: As per Kamen Rider norm. This also has the effect of flinging the affected Chemy out, ready to be captured by Gotchard.
- Fusion Dance: They're formed by fusing human malice with a Chemy. Lachesis later shows that its possible to upgrade Malgams by fusing additional Chemies onto them, with such forms being referred to as Mixtus.
- Hate Sink: The hosts show just how vile and depraved they are before becoming a Malgam and that their fates are well-deserved after being defeated by Houtarou.
- Meaningful Name: They are an "amalgamation" of a Chemy and human malice.
- Multi-Armed and Dangerous: Downplayed. While their appearance presents multiple arms on their bodies, only two are actively moving at any time (usually at least one arm generated from the Chemy for convey its powers), while the extra arms are mummified and wrapped onto their Chemy parts akin to clinging onto them.
- Opposites Attract: A villainous example. The malice of the Malgams' human components seem to resonate with Chemies that are their antithesis. Granted this becomes more of a theory since the later episodes focus less on captured Chemies other than to see them rescued at the end.
- Sudo is Skebows' complete opposite. Skebows is a fun-loving, childish Chemy who simply enjoys playing with other people, particularly kids - Sudo is a treacherous backstabber who is completely consumed by the cares of adulthood, particularly a selfish preoccupation with the accumulation of money over friendship.
- Venomdake is a Chemy who enjoys helping others by aiding in the creation of cures for poisons, allowing them to live their lives to the fullest - Takemoto is a misanthrope who wants nothing more than to drag everyone down to his level of misery and revel in their suffering.
- Gorillasensei seems to be a gentle Chemy despite its great strength - Gouriki is needlessly violent and abuses his strength to sate his own ego.
- Sorting Algorithm of Evil: The first Malgams seen in the show are silver-colored and are created by fusing malicious humans or the Dark Sisters themselves with Chemies, and can be defeated by Gotchard and Valvarad in their base forms. After the first two arcs, the Golden Malgams are introduced, which are usually created by Geryon fusing a Chemy with a Malice Doll, and require the heroes to step up their own game to defeat. The fourth Arc introduces a stronger variant of the Golden Malgams created by fusing a Chemy with multiple Malice Dolls at once, allowing them to go toe to toe with forms like Platina Gotchard.
Three Dark Sisters's Malgams
The Three Dark Sisters themselves have the ability to fuse with Chemies and transform into a Malgam, though Atropos is yet to have shown this ability thus far.Clotho
Portrayed by: Kanon Miyahara (live); Yasuhiko Imai [episode 1], Kenya Saitō [episode 22], Danki Sakae [episode 23-] (suit)
Mantis Malgam
- Special feature/ability: Sickles/fighting
A Malgam formed when the Dark Sister Clotho forcefully absorbed Kamantis.
- Golden Super Mode: After Clotho's Mid-Season Upgrade, the Mantis Malgam is now a Golden Malgam, with the power to match.
- Meaningful Name: The upgraded Mantis Malgam has (Au) tagged at the end of it's name. (Au) is the symbol for gold on the periodic table.
- Mythology Gag: A mantis-themed Starter Villain like the Mantis Yummy from Kamen Rider OOO.
- Razor Wind: One of its favored attacks is a powerful wind that can cut even concrete.
- Slaying Mantis: It's a Malgam based on a mantis.
- Starter Villain: It's the very first Malgam of the show, and the first one Gotchard defeats.
- Sword Beam: With its scythe arms, it can swing out green wind-like energy that cut things from a distance.
Mantis Malgam Saber Tiger Mixtus
A Malgam formed by the upgraded Clotho forcibly absorbing Kamantis and Saberliger after the Saber Tiger Malgam's defeat.
- Mix-and-Match Critters: It has traits of both Kamantis and Saberliger. Most Malgams are only made with one Chemy, and the previous example using multiple used multiple Chemies of the same type; the Mantis Saber Malgam is the first to use Chemies from two different categories.
Gorilla Malgam Rafflesia Mixtus
A Malgam formed by the upgraded Clotho using Gorillasensei and Buglesia.
- Planimal: It's a Malgam with characteristics of both a gorilla and a rafflesia plant.
Lachesis
Portrayed by: Alisa Sakamaki (live), Danki Sakae (suit)
Ant Malgam
- Special feature/ability: Labyrinth expansion/propagation
A Malgam formed when the Dark Sister Lachesis forcefully absorbed Antrooper.
- Acid Attack: One of its attacks is shooting corrosive acid that is powerful enough to melt rock and force Hotaro to depower.
- Ant Assault: It's a Malgam based on an ant.
- Blade Below the Shoulder: Has a massive wing-like blade on its left arm.
- Enemy Summoner: It can summon copies of itself to help in combat.
- The Maze: It can teleport its targets to an underground labyrinth that resembles the interior of a giant ant hill.
Clover Malgam
- Special feature/ability: Stem capture/good fortune

- Arm Cannon: Lachesis can absorb the BamBamboo Chemy on top of Happyclover to transform her arm into a cannon that shoots powerful projectiles.
- Luckily, My Shield Will Protect Me: She can also absorb the Buglesia Chemy on top of the above two to transform her other arm into a shield that can launch bad-smelling neurotoxin
- Plant Person: It's a Malgam based on a Four-Leaf Clover.
- Vine Tentacles: One of its attacks is generating vines to wrap its victim in.
Orochi Malgam
Voiced by: Kenta Kamakari (voice)
A Malgam formed by the fusion of a Geryon-possessed Lachesis and Jyamatanoorochi.
- Breath Weapon: It can fire blasts of plasma that turn anyone it hits into stone.
- He Was Right There All Along: Due to the speed and breadth of its attacks, the protagonists initially believe that it's flying or teleporting around the city. It's not until Houtaro spots that the Malgam still has the bell he shot off that Rinne realizes its true nature and fires The Sun into the sky, revealing that the Orochi Malgam hadn't technically moved from where it was first fought, and had just been stretching out its many heads while using the cloudy weather as cover.
- Multiple Head Case: Defeating its enlarged form requires all of its heads to be defeated, as Houtaro and the others learn the hard way.
- Sizeshifter: It can change into a gigantic form hiding behind a storm cloud and a more typical human-sized form.
Silver Malgams
Sudo/Skateboard Malgam
Portrayed by: Tomokazu Enoki (live), Danki Sakae (suit)
- Special feature/ability: High-speed gliding/energy bullets
A Malgam formed from the fusion of Skebows and a bank robber named Sudo.
- Cool Board: It's able to turn into the evil version of Skebows to go under any obstacle such as cars.
- Fragile Speedster: It's not that powerful in a fight, given that Rinne almost managed to free Skebows from it all by herself were it not for Sudo's strong malice, but it manages to put up a fight against Gotchard due to its speed and agility. After Golddash helps out Hotaro, the fight almost instantly becomes one-sided the moment they catch up.
- No Honor Among Thieves: After a successful bank robbery, he throws his partner-in-crime off a bridge so he could hog all of the loot.
- Pure Energy: One of its attacks is shooting wheel-shaped energy balls that Gotchard was able to deflect.
Takemoto/Poison Mushroom Malgam
Portrayed by: Satoshi Ogasawara (live), Akihiro Hosokawa (suit)
- Special feature/ability: Poison/special spores
A Malgam formed from the fusion of Venomdake and a salaryman named Takemoto.
- Astonishingly Appropriate Appearance: Takemoto has a bowl haircut that makes him resemble a humanized mushroom. His surname even has the kanji for mushroom (茸).
- Be Careful What You Wish For: Invoked. He apparently hates seeing people being happy with laughter, even intending to go on a public murder spree as retribution for it. Fusing with Venomdake however, changes his plans to instead force his victims to "laugh as they wanted" while choking on his poison spores.
- Character Catchphrase: When using the laughing spores: "Laugh! Laugh! Laugh and suffer!"
- Laughing Gas: One of its attacks is shooting a cloud of spores that forcibly induce laughter in victims.
- Luckily, My Shield Will Protect Me: Its mushroom head acts as a shield to block most attacks.
- Mushroom Man: It's a anthropomorphic mushroom.
- Poisonous Person: True to its name, it can shoot poisonous spores that paralyze the target.
Kariya/Submarine Malgam
Portrayed by: Hisashi (live), Danki Sakae (suit)
- Special feature/ability: Intangible diving/torpedoes
A Malgam formed from the fusion of Deepmariner and a man named Kariya.
- Macross Missile Massacre: It can launch torpedoes that can dive in any hard surface and attack their targets.
- Sand Is Water: As a Malgam based on a submarine, it can dive and swim into the ground. It can also make people sink into solid surfaces as if they're water.
- Shadow Archetype: He's this to Supana, who he is pitted against. Kariya utterly objectifies Rinne as a sex object and forces himself on her. While Supana can also be creepy with his implied crush on Rinne, he sees her as a person and is protective of her, helping whenever he sees fit.
- Stalker with a Crush: Kariya is introduced spotting Rinne from afar in #3 and calling her his type, spending the rest of the episode stalking her until he catches up, reappearing at the end of the episode.
- What Happened to the Mouse?: We never see him after his defeat by Supana, and he is never shown being memory wiped or arrested onscreen.
Gouriki "the Golem"/Gorilla Malgam (I)/Jungle Malgam (I)
Portrayed by: Yukio Naya (live); Kenya Saitō [Gorilla Malgam], Danki Sakae [Jungle Malgam] (suit)
- Special feature/ability: Strong-arm/pro-wrestling moves
A Malgam formed from the fusion of Gorillasensei and a former pro-wrestler named Gouriki.
- Blood Knight: Gouriki is so violent and bloodthirsty that when his opponents fail to satisfy his bloodlust, he starts going after the audience in his wrestling matches. Asahi said he's been convicted several times for it.Asahi: Once he snaps, there's no stopping him.
- Crippling Overspecialization: Gouriki is very reliant on his Whirlwind Back Breaker Finishing Move to win fights, able to easily defeat even Gotchard by using it. However, once Houtarou learns the counter to it from Asahi, the fight against him quickly becomes one-sided in Gotchard's favor.
- Crippling the Competition: During a match against a rising star from Asahi's gym, Gouriki cripples him with his signature move, forcing him into early retirement.
- The Dreaded: He's so infamous for his brutality that all of Asahi's students left the gym in fear of him when he crippled its rising star.
- Establishing Character Moment: He's introduced aimlessly wandering the city at night continually muttering "I am the strongest" under his breath before going down a dark alley and bumping into a trio of thugs, triggering a fight. When one of the thugs comes at him with a knife, Gouriki breaks his wrist, and then his back with the "Whirlwind Back Breaker."
- The Faceless: The production notes for #25
reveal that Gouriki was the Jungle Malgam that attacked the Academy 10 years ago, though his face is never shown. - Killer Gorilla: It's a Malgam based on a gorilla.
- Mythology Gag: His wrestling name, theme of strength, color scheme (gray and brown), and fist motif are similar to the Golem Megid from Kamen Rider Saber.
- The Nicknamer: Nicknames Houtarou "Baby Face" after beating him in their first fight.
- Super-Strength: As expected of a kaijin with Gorilla-based powers. However, even in human form Gouriki's fearsome strength is a force to be reckoned with as he's capable of crippling other people with his bare hands. His reputation for strength is even lampshaded by his wrestler name, "Gouriki the Golem."
- He's also the first Malgam Houtarou struggles to contend with in terms of power. It takes grueling training with Asahi and Wrestler G along with the physical might of AntWrestler form to take him down.
Boruto Namarizaki/Hawk Malgam
Portrayed by: Shogo Amo (live), Danki Sakae (suit)
- Special feature/ability: High-altitude flight/marksmanship
A Malgam formed from the fusion of Hawkstar and rogue Alchemists' Academy student Boruto Namarizaki.
- Ain't Too Proud to Beg: He's an insufferable narcissist, but when Minato comes to erase his memory he backs away from him while pleading for his memory to remain intact.
- Break the Haughty: Supana revealing to not remember him at all is what finally gives him a reality check about his delusions, before Minato erases his memories.
- But for Me, It Was Tuesday: For all his desire for revenge against Supana for losing to him in the A-Class alchemy exam finals, Supana actually doesn't remember defeating him, much to his chagrin.
- Casting Gag: Shogo Amo had previously portrayed a hammy self-proclaimed rival, as well as a human-turned-beast monster over a desire for petty revenge. Here as Boruto, he's a combination of both.
- Chuunibyou: His over-the-top attitude is contrasted with Supana's cool demeanor.
- Evil Is Petty: He gets corrupted into a Malgam just because he got trounced by Supana during the A-class exam.
- Eye Beams: Its Glare Shot ability.
- Feathered Fiend: It's a Malgam based on a hawk.
- Feather Flechettes: One of its attacks is launching a barrage of razor-sharp feathers at the enemy.
- Foil: He's the polar opposite of Supana in every conceivable way; Supana is cold, pragmatic, and straight to the point, but he genuinely wishes the best for people. Boruto, however, is a Hot-Blooded Large Ham who has a flair for the dramatic and prefers flashy displays, and unlike Supana does things solely to satiate his titanic ego. Supana also uses Chemies with their consent, more-or-less, while Boruto forces Hawkstar to fuse with him to get his revenge.
- Genre Savvy: Zigzagged. While he's canny enough to realize Rinne is a weak point for both Houtarou and Supana and prevents Rinne from using alchemy against him, he's also not quite aware that he's emphatically not a major character, which makes him an easy target once Supana and Houtarou team up.
- Green-Eyed Monster: Is jealous over how Supana ended up better than him. Bonus points in that his Alchemist Ring has a green gemstone.
- Large Ham: And how! For a one-off villain, Boruto practically devours the scenery in every scene he's in, with every single action he takes exaggerated to ridiculous levels as if he were a cartoon character.
- Meaningful Name: His first name is derived from "bolt", which is a type of screw tightened using a spanner, while the namari in his last name is Japanese for "lead", a soft, malleable metal.
- Nominal Hero: He was once an Alchemist Academy student, but even back then he only joined to brag about his ego. Sure enough, if his ego is bruised, he'd resort to becoming a Malgam and murdering an innocent to get what he wants.
- Revenge by Proxy: He decides to get even with Supana by kidnapping Rinne, forcing his so-called rival to confront him to rescue her.
- Shadow Archetype: He highlights both Houtarou and Rinne's traits taken to dark levels.
- Like Houtarou, he considers himself Supana's rival, but while Houtarou's one-sided rivalry towards Supana plays a secondary at best role in his life, Boruto lets his obsession rule over his life. The basis of the rivalries affects how Supana sees them, with Houtarou being treated with personal disdain due to their clashing ideologies and goals, while Boruto is seen as a Unknown Rival with the implication that Supana had too many to count. Additionally, while their names are similar, Boruto is also the scion of a prestigious family, a stark contrast to Houtarou's middle-class upbringing.
- Like Rinne, he's the heir to a notable alchemical family and is a member of the Alchemists' Academy. Rinne barely interacts with Supana despite her Morality Pet status for him and rarely antagonizes him unless he acts first, while Boruto obsesses over his defeat by Supana and will attack first whenever he can. Additionally, Rinne is dutiful in her alchemist duties and will stick to the rules as closely as possible, while Boruto's egomania means that not only does he neglect his duties as an alchemist, but he doesn't give a damn for any rules if it means he'll get what he wants.
- Small Name, Big Ego: He dedicates his life to make Supana pay for defeating him, only for him to be considered as a small fry in Supana's life.
- Stalker without a Crush: He follows Supana in the shadows just so he can find the right moment to enact his revenge.
- Unknown Rival: Much to his dismay, Supana doesn't remember who he is, meaning Boruto would never get any satisfaction even if he did go through with his revenge.
- Villainous Breakdown: Goes utterly berserk when Supana flatly asks who the hell he is.
Kenji Sunayama/Dragonfly Malgam
Portrayed by: Seiha Naitō (live), Naoya Iguchi (suit)
- Special feature/ability: Stable flight/stinger firing
A Malgam formed from the fusion of Greatonbo and Riku Sunayama's father Kenji.
- Abusive Parents: It doesn't get more abusive than turning into a monster to attack someone his son just met solely because he's not devoting his life to his studies. He gets better about it though after taking a Rider Kick to the head.
- Disproportionate Retribution: Your son is playing with a cute cactus partner? Terrify him into submission with deadly spikes!
- Dreadful Dragonfly: The Chemy for this Malgam is the dragonfly-themed Greatonbo.
- Education Papa: He only wants his son to focus exclusively on his studies and will not hesitate to yell at him if he deviates even slightly, not giving a damn about his son's own two cents on the situation. Lachesis's intervention only makes him worse, as he is more than willing to openly attack people who get close to his son just because he thinks they distract him from studying.
- Easily Forgiven: While the other Malgam hosts were left for the authorities to deal with, all Kenji gets as comeuppance is getting his memory wiped of the events and learning to loosen up with his son.
- Foil: He serves as one to Hotaro's mother. While Tamami runs a small restaurant and is a kind, caring, and open-minded mother who supports and respects Hotaro's decisions, Kenji runs a large business firm and is a stern, temperamental, and apathetic father who doesn't care about what his son thinks of his plans for him.
- Hate Sink: While the series is practically full of these characters, including an unscrupulous robber, a would-be serial killer, and a violent thug, they at least had the decency to only attack strangers (or in the case of Boruto, people who couldn't care less about them). Kenji, however, is heads and shoulders above them, as being willing to attack his own son makes him the worst of the Malgam hosts yet, and that's not counting the Dark Sisters. Lachesis even notes just how much malice his Malgam form generates, showing that there's something clearly wrong with the man. Ironically, he's also more repentant after his defeat, which is more than what likely can be said about the hosts before him.
- Heel Realization: For all of his big faults, he does end up apologizing to his son after being defeated. This may be part of why he gets off relatively lightly.
- Irony: Not that he would have really known given the circumstances, but becoming a Malgam meant that he was using one of the very Chemies that he was trying to have his son get rid of.
- My God, What Have I Done?: The realization that he came close to nearly murdering his own son scared him so much that he immediately drops his abusive habits and vows to be a better father for the future.
- Spike Shooter: It's main attack involves shooting spikes from its head tail.
- Would Hurt a Child: And that child is his own son!
- It's implied this is a result of his transmutation into a Malgam. While not exactly a model parent before, both Houtarou and Riku himself believe that Kenji truly does care for Riku. After his defeat, he is beside himself with regret, horrified at his actions toward Riku.
Yabuki/Jungle Malgam (II)
Portrayed by: Takamitsu Fukuchi (live), Danki Sakae (suit)
- Special feature/ability: Rapid growth
A Malgam formed from the fusion of Junglejan and a criminal named Yabuki.
- Maniac Tongue: Licks the blade of his knife before transforming.
- Plant Person: It's a Malgam based on a tropical tree.
- Sizeshifter: It can change sizes from human-sized to skyscraper level.
- Vine Tentacles: Or in its case, root tentacles.
Tsurugi Himeno/Battery Malgam (I)
Portrayed by: Ryunosuke Moriyama (live), Naoya Iguchi (suit)
- Special feature/ability: Electric shock
A Malgam formed from the fusion of Raidenji and Hijiri Himeno's brother Tsurugi, a serial arsonist.
- Broken Pedestal: To Hijiri, who fervently believed in his innocence, only for him to eventually reveal to her that he didn't regret his crimes, causing her to overflow with malice and become a Malgam.
- Freudian Excuse: The years of stress from caring for his little sister after their parents died eventually broke him, and he turned to arson as a means of release.
- Hate Sink: Another standout example; the fact that he remains completely unrepentant (at least if everything he went through didn't knock some sense into him) after his true colors are revealed only makes his attempts to kill his sister all the more heinous. The previous one, Kenji, at least showed some remorse for similar behavior, but for Tsurugi, his Freudian Excuse isn't treated as a legitimate excuse, as the role gets reversed as his Malgam powers moves to his vengeful sister upon his defeat.
- I Wished You Were Dead: Tells Hijiri straight to her face that he hated having to take care of her.
- Psycho Electro: It's a Malgam with electricity-based powers that also has an unhinged criminal as a host.
- Pyromaniac: In his own words, he felt "freed" by the sight of fire.
- Sibling Murder: Tsurugi seeks to kill Hijiri upon escaping the police. Their positions are later reversed.
???/Spider Malgam (I)
Portrayed by: Unknown (live), Danki Sakae (suit)
- Special feature/ability: Thread capture/trap
A Malgam formed from the fusion of an unidentified man and Catchula.
- Chest Blaster: Its chest is in the shape of a spider's head, which can fire red energy blasts from the eyes.
- The Faceless: Its host's face is conveniently blurred out.
- Projectile Webbing: It can fire these from its hands, as expected of its Animal Motif.
- Spider People: It's a Malgam based on a spider.
- We Hardly Knew Ye: We don't even get to see what the host looks like, who he is, or what his motivations are.
Wheel Malgam (SPOILERS)
Portrayed by: Yasunari Fujibayashi (voice), Yuji Nakata (suit)
A Malgam formed by the fusion of Madwheel and an enraged Supana Kurogane.
For more information on its host, see Supana's folder here.
- And Then John Was a Zombie: One of the main characters turns into a Malgam.
- The Berserker: Given that the form is driven by his grief, it lashes out at everyone, including those trying to help it like Houtaro and Rinne.
- Body Horror: Its body tears apart Valvarad's form and systems, resulting in a very visceral appearance, most notably with its head being the result of Valvarad's face getting ripped off.
- Body Motifs: The face, since it reflects how Supana's new change of face, the fact that his aloof nature has been shattered, and how he's turned from a warrior into a monster.
- Evil Counterpart: It serves as one to Supana's standard Valvarad form, given that it's essentially a corrupted version of it fused with a Malice Doll, in this case Supana's body.
- Family-Unfriendly Violence: A self-inflicted case as the Wheel Malgam, which tears off the Valvarad mask during the transformation — because Valvarad is also suggested to not be a suit, Supana is effectively degloving his entire skull and holding its remains in a tumorous third arm while stuck in the form.
- Gold-Colored Superiority: It has dirty gold among its colors, and it's just as deadly as the Angel Malgam with its fire powers, if not more. It is also the first Golden Malgam to not be formed by the fusion of a Malice Doll and a Chemy.
- Playing with Fire: The Wheel Malgam can create and use black flames.
- Rule of Symbolism: Supana transforms into the Wheel Malgam after he rips off the helmet of Valvard, just after the facade of a haughty high-level alchemist has been basically shattered.
- Tear Off Your Face: Supana first turns into Valvarad but then rips off his face to become a Malgam.
- Transformation Horror: The way Supana transforms into the Wheel Malgam: he transforms into Valvarad, but then the Malgam breaks through, ripping off his hemet -which is actually his face!- and makes the right shoulder wheel into an arm, and the lower body is turn into the Malgam legs, with the pipes and wires underneath being like a high skirt.
- Transmutation: Supana can change between his human form and Malgam form.
- Walking Spoiler: It is really hard to keep Wheel Malgam's human identity secret.
- Weaponized Car: As the Wheel Malgam, it uses the right tire arm to launch purple tire constructs.
Okitsune-sama/Kyūbi Malgam
Portrayed by: Unknown (voice), Danki Sakae (suit)
A Malgam formed from the fusion of Ninetail and Okitsune-sama, the guardian spirit of Kokonotsu Village.
- Anti-Villain: It attacks the villagers, but only because it wants to lure Gotchard to use his Rider Kick to dig through the hot springs needed to save the village. Later Ninetail Chemy reveals that it was trying to help the village too.
- Batman Gambit: It turns out to be the mastermind of one, luring Gotchard into a fight and a Rider Kick in order to open up a hot spring and revitalize Kokonotsu.
- The Dog Was the Mastermind: The Malgam attacking the villagers and putting them into weird positions? Turns out it was the local kitsune spirit after all.
- Expy: This Malgam shares many similarities with Kamen Rider Dooms Geats, namely in that they are antagonistic beings with benevolent intentions using golden kitsune powers to achieve their goals.
- Foreshadowing: Unlike other Malgams, its appearance simply features Ninetail with a band tied around its head and without any sign of abuse or twisted attributes of the said Chemy, with its front paws together in a prayer. This hints that this Malgam's identity is the kitsune spirit guarding the village; out of benevolent intentions, it uses its Malgam identity to lure Gotchard into discovering the hot springs to save the village from becoming a landfill.
- Another subtle foreshadowing involves when it appears in front of Rinne and not only it does not attack her but she isn't scared nor shocked even when they are face-to-face.
- Master of Illusion: It can trap people in an illusion that includes a massive eyeball monster, making them afraid.
- Physical God: Incredibly agile and durable, casually blocking, deflecting, and dodging almost every attack Hotaro throws at it. Ninetails possessing a guardian spirit instead of a Malice Doll or human probably helps.
- The Voiceless: Does not speak at all, apart from grunts and laughter. This necessitates it communicating through less direct means such as gestures and esoteric pranks.
- Weak, but Skilled: Downplayed. It's one of the most technical foes Hotaro has ever faced, and he can barely lay a hand on it much less land a hit. It's not, however, strong enough to blast through the village's mountain to release the spring water within, requiring the aid of a particularly supercharged Gotchard finisher to do so.
Criminal/Anomalocaris Malgam
Portrayed by: Hiroyuki Muraoka (live/suit)
A Malgam formed from the fusion of Akumanocaris and an unnamed criminal.
- Combat Tentacles: It uses its tentacles to fight off Gotchard, Renge, and Sabimaru.
- Last Villain Stand: Even when his Malgam form is gone, the criminal attempts to attack Renge and Sabimaru to evade arrest.
- No Name Given: The criminal's name is never revealed to anyone.
Saigetsu/Ark-One Malgam
Portrayed by: Katsuya Takagi (live), TBA (suit)
A Malgam formed by fusing Gokigenmeteon, Sayzombie, Gigalodon, and Nammonite to Saigetsu while still transformed into Kamen Rider Ark-One.
See here for tropes related to Saigetsu's original appearance and regular Rider forms.
- Magitek: It's an alchemical transmutation grafted to the nanite-based Kamen Rider Ark-One.
- Mythology Gag: It's made mostly out of Ancient Chemies; the Ark specialized in Zetsumerisekeys which were also based on extinct animals. Sayzombie's incorporation brings to mind Eden, whose Zetsumerisekey was based on a human.
- The Worf Effect: In its home series, the Ark was a nearly-unstoppable AI that, despite being Maddened Into Misanthropy, ultimately needed the malice that it despised to sustain itself, and created Kamen Rider Ark-One through As as the first of many plans to create more conflict from hatred. Here, Ark-One is reduced to the thrall of Malgam transmutation, itself the product of concentrated human malice.
Golden Malgams
Improved Malgams that are primarily created through fusing Chemies with special homunculi known as Malice Dolls, though they can be created from humans as well.
In General
- Gold-Colored Superiority: They are shown to be on a level above previous Malgams through their gold bodies.
- Killed Off for Real: Unlike with the ones with a human host, Malgams created using Malice Dolls only result in the Chemies' release rather than just separating one from the host, as the Malice Dolls are usually just outright destroyed.
- Made of Evil: In contrast to humans, who are generally born "neutral" at best and often become evil later on in life, Malice Dolls seem to have been created by Geryon for the express purpose of being as vile as possible for his experiments. Atropos claims they are so evil, they need to be kept sealed at all times when not being utilized by Geryon.
- Our Homunculi Are Different: They are different from previous Malgams in that they are formed from a Malice Doll rather than a human being, or from a fusion with the Dark Sisters.
- Atropos tells Lachesis they are the "older brothers" of the Dark Sisters, despite being kept immobile to the point of being inanimate objects.
- Puppeteer Parasite: It's subtle, but their suit designs paint the Malice Dolls out to be this to the Chemies they're fused with, as the golden parts representing them are molded around what represents the Chemie to various degrees. The golden body of the Cerberus Malgam, for example, includes a hand holding Yoacerberus's chain.
- Sealed Evil in a Can: The Malice Dolls are kept under Alchemical seals when not in use. Geryon also keeps them all stored in a special pocket dimension he can access at will.
Moon Malgam
Portrayed by: Taito Ban (voice), Danki Sakae (suit)
A Malgam formed by Geryon fusing a Malice Doll and Neminemoon.
- Healing Factor: It establishes the Golden Malgams as threats above previous Malgams by tanking a finisher from Super Gotchard X-Rex. However, it DOES have an upper limit to how much it can take as Fire Gotchard damages it to quite a degree that even as it's attempting to undo the damage done, it cannot and instead disintegrates away.
- Making a Splash: It can use its blue left arm to do water-based attacks, reflecting the moon's effect on the tides. A closer look reveals said arm to be drool coming out of the Malgam's "head".
- Mythology Gag: The official website mentions its design as a homage to Baseball Mask from Himitsu Sentai Gorenger.
- Resting Recovery: It can dive into the shadows and sleep in order to recover from damage.
- Sand Is Water: Like the Submarine Malgam, it can dive into solid surfaces as if it were water. That being said, though, it primarily summons other moons to cast shadows to pull it off, making it look more like the Malgam just makes it's own portals.
- Screw This, I'm Outta Here: The instant it sees Fire Gotchard charging up the finisher the Moon Malgam begins portalling away as fast as it can while whimpering like a coward.
- Sinister Scythe: Wields a crescent moon-shaped scythe named Nemotos as its weapon.
- Too Dumb to Live: After a slight beating from Fire Gotchard, it attempts to kill Rinne and co in front of him. Note that this was after seeing firsthand that said Rider had access to a Flash Step. He gets embedded into both a gravel pile and the literal ground for his trouble.
Cerberus Malgam
Portrayed by: Kazuya Ichijō (voice), Yohei Fujita (live), Danki Sakae (suit)
A Malgam formed by Geryon fusing a Malice Doll and Yoacerberus.
- The Berserker: It's a powerful Malgam that attacks both friend and foe alike, necessitating it to be controlled through music.
- Breath Weapon: Its middle head spits out fire, its left head breathes out thunder, and its right head blows out ice.
- Chain Pain: It has a gold chain on its head to tie up anyone hapless enough to get in its way.
- Fire, Ice, Lightning: Its three heads control the aforementioned elements.
- Healing Factor: If any of its copies are destroyed, the head will be all that is left. That head will regenerate the bodies of any clones remaining.
- Hellhound: It's based on the Cerberus of Greek Mythology.
- Me's a Crowd: It can split into three single-headed versions of itself, each capable of fire, ice, and thunder abilities respectively.
- Music Soothes the Savage Beast: Geryon gives Atropos a set of pan pipes meant to keep it in line. This is a reference to how Orpheus used music to soothe the original Cerberus and get past it in his quest.
- Purple Is Powerful: Once it fuses with Yoacerberus it becomes a giant purple-colored Cerberus-like beastman that requires the teamwork of both Fire Gotchard and Majade to take down.
- Real Men Eat Meat: Its Malice Doll awakens into a humanoid form through its desire to eat meat. It's not enough to make it consider eating Houtaro's meat cream puffs, however.
- Restraining Bolt: Its wild tendencies can be held in check by playing music to it.
- Too Spicy for Yog-Sothoth: Upon eating Houtaro's newly made cream puffs with meat, it immediately hates the taste and spits them out.
Angel Malgam
Portrayed by: Anri Katsu (voice), Danki Sakae (suit)
A Malgam formed by Geryon fusing a Malice Doll and Angelead.
- Actor Allusion: Anri Katsu was previously Killbus; the Angel Malgam is the monster form of one half of Gotchard AngelTera, which sports a reddish helmet with a similar crest and fins as the one used by Kamen Rider Killbus.
- Crucified Hero Shot: Its design invokes one, with the angel on its design hanging off of its body like it were hanging off a cross. This symbolizes how the Malgam perverts the idea of angels as benevolent beings.
- Feather Flechettes: It can launch its feathers to attack.
- Good Powers, Bad People: The ability to bring people back from the dead for brief periods of time could be used to help them and their loved ones find closure, rather than as a means of tormenting both them and the living as this Malgam does.
- Light Is Not Good: White is among its color schemes, but it's anything but nice. It even manages to push Supana off the edge to the point where he breaks and becomes another Malgam.
- Manipulative Bastard: The first part of its scheme to break Supana involves summoning an illusion of his dead parents to call him over. Supana takes the bait, hook, line, and sinker. Kyoka is understandably horrified when Supana informs her about his parents, knowing they're both dead.
- Necromancy: It can somehow bring back copies of dead people, which it can use to torture them psychologically as in Supana's case.
- Soft-Spoken Sadist: It speaks in a calm, almost soothing voice that would fit for a heavenly being, but takes great pleasure torturing Supana psychologically, and laughing as it fights.
Saber Tiger Malgam
Portrayed by: Yu Shimamura (voice), Danki Sakae (suit)
A Malgam formed by Geryon fusing a Malice Doll and Saberliger.
- Nemean Skinning: As a Malgam the sabertoothed cat on its design is draped over its body, with the legs facing upwards.
- Red Oni, Blue Oni: It serves as the calm, patient ally to the Hot-Blooded Clotho.
- Sword Beam: More like claw beams since it can materialize and launch energy blades from its claws.
Pteranodon Malgam
Portrayed by: Reio Tsuchida (voice), Danki Sakae (suit)
A Malgam formed by Geryon fusing a Malice Doll and Warptera.
- Flight: Its Pteranodon wings grant it the ability to fly, including into and out of its portals.
- Thinking Up Portals: Its primary ability is to create warp portals that it can travel in and out of, as well as to selectively capture material to send from one portal to another as it does to the Chemy Cards.
- This Is a Drill: It has a drill mounted on its left arm that it uses for offense.
Dragon Malgam
Portrayed by: Shintarō Asanuma (voice), Danki Sakae (suit)
A Malgam formed by Geryon fusing a Malice Doll and Dragonalos.
- Breath Weapon: It can breathe fire through the dragon head mounted on its chest.
- Flight: It can fly using the dragon wings on its head.
- Lightning Bruiser: It's ability to fly renders it a highly fast and maneuverable opponent, but the Dragon Malgam's raw power is enough to overpower and damage even Iron Gotchard. This combined with the aforementioned speed means that not only is Iron Gotchard's durability rendered moot, but it's poor mobility is mercilessly exploited to no end.
- Our Dragons Are Different: It's a hybrid of a dragon created through alchemy and a powerful homunculus.
- Unskilled, but Strong: It's the first Golden Malgam created with a Level 10 Chemy, and it certainly gives the heroes fits, but it mainly relies on its brute force attacks like its fire breath and claws. Kamen Rider Wind easily handles it through his combination of power and experience as an alchemist.
Land-grabbers/Karakasaobake and Fairy Malgams
Karakasaobake Malgam portrayed by: Takashi Nishina (live), Masato Tsutamune (suit)
Fairy Malgam portrayed by: Ryudai Onikura (live), Naoya Iguchi (suit)
A pair of Malgams formed by Atropos fusing two unnamed land-grabbers with Berosol and Carery.
- Combat and Support: During their fight against Gotchard, Karakasaobake serves as the more active combatant while being empowered by Fairy.
- Gold-Colored Superiority: Downplayed; though they are Golden Malgams, a X-Rex-empowered Platina Gotchard is able to throw off Karakasaobake's tongue-binding attack, with Fairy's power during their Combination Attack being the main threat.
- No Name Given: Their names are never revealed.
- Spin Attack: Their Combination Attack involves one.
Mammoth Malgam
Portrayed by: Seiichirō Yamashita (voice), Danki Sakae (suit)
A Malgam formed by Atropos fusing four Malice Dolls and Blizzammoth.
- Four Is Death: It's composed of four Malice Dolls fused together with Blizzammoth, and is so far shown to be strong enough to give Platina Gotchard fits.
- An Ice Person: It blows deadly, icy winds that can freeze its targets solid.
- Logical Weakness: Being an ice-based Malgam, it's naturally weak against fire and heat. Majade uses The Sun to melt its ice away, and Gotchard uses Inphoenix to power himself up with fire attacks to defeat it.
- You Killed My Father: The Malice Dolls are motivated by their desire to avenge Geryon's apparent demise, which their "sister" Atropos makes use of.
Kraken Malgam
Portrayed by: Tsubasa Yonaga (voice), Yuya Nawata (suit)
A Malgam formed by Atropos fusing a group of Malice Dolls and Mackraken.
- Achilles' Heel: Losing its cephalopod body prevents it from storing its ink within itself and creating its illusions.
- Kraken and Leviathan: It's a fusion of a group of homunculi and the kraken-based Chemy.
- Master of Illusion: It can spew its ink to cover its targets in an inky landscape where it can change its appearance and that of others.
