[[folder:Zofis]]
!!!'''Voiced by:''' Creator/ToshikoFujita (JP), Creator/SusanSilo (EN), Valle Acebrón (SP), Joana Brito (LA)
!!!'''Spell Specialization:''' [[HavingABlast Explosions]]
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/zofis.png]]
A male 14-year-old Mamodo with an androgynous and doll-like appearance, and the first major villain that Zatch faced. He possesses the natural ability to manipulate others' hearts, and began the battle by turning his partner Koko from selfless and kind to as malicious and ruthless as he. He revived the Ancient Mamodos and brought them under his control in an attempt to become king. Though an imperial sort who would prefer leaving the fighting to others, his ability to fly, genius intellect, and Explosion-based spells make him no pushover if he must dirty his own hands.
----
* ArcVillain: Zofis is the main villain of the Ancient Mamodo arc, which concludes with his defeat.
* ArchEnemy: To Sherry and Brago. Sherry absolutely despises Zofis for manipulating Koko and refuses to allow anyone else to take him out. And, despite his attempt to kill Sherry when they first met, Zofis actively avoids a confrontation with them, because Brago absolutely terrifies him.
* BadBoss: All of his minions, and even Koko, are just tools for him to become king.
* BigEater: All Mamodo have big appetite, but in Zofis' case, he prefers huge feasts fit for a king, which mirrors his personality and ambitions. Also, unlike other Mamodo such as Zatch or Brago, Zofis doesn't scarf down his meals [[JabbaTableManners like an animal]]. Quite the opposite, as shown in ep.69.
* CombatPragmatist: At one point he announces his arrival by blasting another demon's book before they even knew he was there.
* DidntThinkThisThrough: He points out to Sherry that she ''can't'' kill him, because then he couldn't erase Koko's memories, meaning she has no choice but to send him back to the Mamodo world. Brago points out that once he gets back, there's nothing stopping Brago from coming after him.
* DirtyCoward: Hides behind his army of Thousand-Year-Old mamodo, who he keeps in line with the empty threat of returning to stone. When Brago finally confronts him, he spends most of the battle running away, and when he's finally taken down, he's a teary mess.
* EffeminateVoice: His makeup and dress already make him effeminate enough, but the fact that he's voiced by women in all languages make it really impossible to tell he's male without looking into his pronouns.
* EvilSorcerer: Unlike most Mamodo, Zofis has powers that go far beyond his book spells. He can manipulate minds and hearts through hypnosis, extract memories with remarkable precision, and fly unaided.
* {{Expy}}: His look, personality, and even his attacks are very reminiscent of Freeza from ''Franchise/DragonBall'', and in the dub's case he even sounds like Freeza's old dub voice [[note]] by vitue of Susan Silo doing her [[WesternAnimation/XiaolinShowdown Wuya]] voice [[/note]].
* FailedASpotCheck: Subverted. Zofis, despite his strong perceptive abilities, somehow completely missed that Brago had intercepted the spell Zofis had shot at Sherry when they first met. Brago flat-out refuses to believe this and comes to the conclusion the Zofis had indeed noticed him and fled out of fear. Zofis' TearsOfFear are all the confirmation he needs.
* FangsAreEvil: He has a mouth full of fangs that he shows off when he's making the point of how evil he is.
* FauxAffablyEvil: He usually speaks in a calm, polite tone, even when trying to kill the heroes.
* FemmeFatalons: He's an utterly evil SissyVillain with long, red nails.
* HavingABlast: His powers are centered around [[StuffBlowingUp explosions]].
* HellishPupils: His eyes turn yellow/red with slitted pupils when he's being particularly evil.
* HypnotizeTheCaptive: Because Koko refused to be Zofis' partner, he used his power to corrupt her mind and heart so she would enjoy doing evil with him. Sherry is determined to defeat Zofis and free Koko from his control.
* InferioritySuperiorityComplex: There are hints that he felt inferior back in the mamodo world, but as the BigBad, he styles himself like the king he intends to be.
* KnightOfCerebus: The series takes a notably darker turn during his arc, and he's one of the first villains to have absolutely nothing funny about him.
* ManipulativeBastard: Literally; he has the power to manipulate the hearts and mind of humans and Mamodos alike. Even when he has to use mundane methods like against Sherry, he displays a thorough understanding of how to mentally break people.
* SissyVillain: His face, lipstick, colored fingernails, dress, and even his voice (to an extent) are all extremely effeminate, which somehow makes him even creepier.
* SmugSnake: He actually is incredibly powerful and can do things such as fly, teleport, and mentally dominate others without the use of his book. But when faced with someone he knows is his equal or superior, he isn't as smug.
* TyrantTakesTheHelm: His ultimate goal is to become king of the Mamodo world and rule with an iron fist. [[spoiler:He fails.]]
* VillainousBreakdown: He starts losing his composure when Brago and Sherry enter the conflict. Them singlehandedly defeating his army, Brago's spell actually hitting him, and Sherry becoming immune to his manipulations all push him farther into breaking down. By the time Brago threatens to hunt him down in the demon world, he's reduced to a sobbing wreck.

[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/koko_gbgm_5.png]]
An 18-year-old French woman who grew up in poverty. Kind and outgoing, she intended to seize her future with her own hands by attending a university. Shortly after she was accepted, Zofis came into her life and, after she refused to help him, brainwashed her into a cold and malicious individual.
----
* AffablyEvil: She rarely loses her cute, smiling demeanor even when she's being evil.
* BloodbathVillainOrigin: After Zofis corrupted her, Koko's first act of evil was to burn her entire hometown and everyone in it to the ground.
* BrainwashedAndCrazy: Zofis used his mind controlling powers to brainwash Koko and transform her into a sadistic person who enjoys doing evil with him.
* ChildhoodFriends: She has been Sherry's OnlyFriend since childhood.
* CuddleBug: A villainous example: Koko sure likes to hug Zofis from behind. But the fact that she's brainwashed the whole time makes it all look very creepy and squicky.
* DamselInDistress: She was kidnapped and brainwashed by Zofis. Sherry's main goal for joining the Mamodo Battle is to rescue Koko from Zofis' control.
* DarkAndTroubledPast: Because they were poor, her family was forced to steal in order to gain the little food and comfort they had, and Koko herself was labeled as a thief because of it, even though she was innocent. Realizing that she would never be worthy in their eyes, Koko chose not to give in to despair and focus all of her energy into her work and studying for school. Unfortunately, Zofis forced her to become his partner and corrupted her mind to make her as sadistic as he is.
* InterclassFriendship: With Sherry. Koko is a poor girl and Sherry is a rich girl, but they have been best friends ever since they can remember.
* LaserGuidedAmnesia: Zofis removes all memories of her actions while evil. He refuses to do so until Brago tells him that if he doesn't, he will personally make Zofis's life in the demon world a living hell.
* LivingEmotionalCrutch: To Sherry. Koko was Sherry's OnlyFriend and sole emotional support for most of her life. When her mother's cruel abuse pushed her to the point of suicide, Koko was the one who saved Sherry and motivated her to live on.
* MindControlEyes: Under Zofis' influence, her eyes are blank and inexpressive, a sign that she really is brainwashed and not simply acting on her repressed desires like Zofis claims.
* MoralityPet: Sherry's friendship with Koko and devotion to freeing her from Zofis are the first indications of her softer side before she starts [[DefrostingIceQueen defrosting]].
* MoreThanMindControl: Zofis attempts to convince Sherry it's this. [[spoiler: It ''almost'' works. Zofis also attempts to invoke this: unlike other people whose minds Zofis simply controlled, Zofis created [[SplitPersonality an entirely different personality]] out of the dark feelings in Koko's heart so that she would be his bookkeeper. Zofis restores her heart to normal after he gets beaten.]]
* PutOnABus: Despite her being Sherry's initial reason for fighting, she totally disappears after Zofis is sent back. Justified, in that she goes off to college and Sherry wouldn't want to remind her of the battle anyway.
* RebuiltPedestal: [[spoiler:Koko, under Zofis' control, tries to break Sherry's spirit by revealing that she actually hates Sherry and is a truly evil person all on her own. In the end, this really is all a trick of Zofis's, and Koko really is the good friend Sherry remembered her being.]]
* SomethingOnlyTheyWouldSay: [[spoiler:Her earrings are styled after some rings she made for Sherry that were supposed to serve as talismans to ward off evil. When Sherry realizes this, that's her proof that the real Koko under Zofis' brainwashing is calling for help.]]

!!Zeno and Dufort
[[folder:Zeno/Zeon]]
!!!'''Voiced by:''' Creator/UraraTakano (JP), Debi Derryberry (EN), Sara Vivas (SP), Creator/GabyUgarte (LA)
!!!'''Spell Specialization:''' [[ShockAndAwe Lightning]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/0zeon_29.png]]
A male 6-year-old humanoid Mamodo and a warped doppelganger of Gash's, even having lightning spells of his own, he was responsible for stealing Zatch's memories. He is later revealed to be one of the four prodigies with the moniker 'Thunder Emperor'.
----
* AdaptationalVillainy: In the manga, Zeon does start out rather dickish but as the battle goes on we start to see he does have a noble side and that his actions were purely driven by jealously [[spoiler: which he eventually overcomes once he sees Zatch's past]]. In the anime, no such development exists, he's evil through and through and has nothing but contempt for Zatch to the bitter end, even when he's beaten. This was because the author had broken his hand as he was in the midst of the story arc and the anime rapidly caught up before he could do the battle between Zatch and Zeno. So the animation staff just had to go with anything and just ran with what they had.
* AllEncompassingMantle: Zeno's clothes are theoretically exactly the same as Zatch's (albeit a different color), but his always seems to be billowing ominously while Zatch's generally just hangs down loosely like a dress.
* ArchEnemy: To Zatch. He's responsible for Zatch's amnesia and his burning hatred of Zatch is his motivation for most of the tournament.
* BigBad: For the last half of the Faudo arc, and for most of the series seeing as he's the one who removed Zatch's memories.
* BloodKnight: Zeno is very ruthless and it was something he inherited from his father. [[spoiler: This reason is exactly why King Bell gave Bao to Zatch. Bao consumed so much darkness, the spell became dangerous and Zeno, possessing his father's wrath, would've been consumed by it. Contrast this to Zatch, who not only manage to resist it, but ''purify'' Bao.]]
* CainAndAbel: The Cain to Zatch's Abel, though they get better.
* CharlesAtlasSuperpower: His spell selection is similar to Gash's, meaning his feats of extreme strength and speed come from pure physical training.
* TheDreaded: He's feared as "Thunder Emperor Zeno" due to the TrainingFromHell that puts him at a far higher level than most mamodo children [[spoiler: and being the son of the current king.]] Riou, who is no slouch himself, is trembling when they come face-to-face.
* ElementalWeapon: Unique to Zeno is the spell Sorudo Zakeruga, a giant blade made of lightning.
* EvenEvilHasLovedOnes: Even at his worst, Zeno genuinely cares about Dufort. The feeling is mutual, as Zeno is probably the only living thing that Dufort cares about at all.
%%* EvilTwin: He's an evil, white-haired version of Zatch. [[spoiler:Turns out he's Zatch's actual twin brother.]]
* FlashStep: Spams this, often to get behind opponents.
* FreudianExcuse: His grudge against Zatch? [[spoiler:He believed that, since Zatch got the incredible power of Bao, and he himself had to go through TrainingFromHell, that his parents favored Zatch. His HeelRealization hits when he realizes Zatch's bad past yet never wavered from his kind self while also learning Zatch was given Bao to protect Zeno from it.]]
* HardWorkHardlyWorks: Part of what drives him. [[spoiler: He feels driven to surpass Zatch's Bao Zakeruga with his own power, born from his TrainingFromHell. If he can do so, he'll prove to himself that the suffering of said training was actually worth something. He actually is stronger than Zatch during their fight, but he loses because Zatch matches his and Dufort's suffering and the power coming from it with the care from his friends, empowering Bao.]]
* TheHeavy: His actions kickstart the plot, and he's the driving force behind the second major arc of the series.
%%* HeelFaceTurn: [[spoiler: His last act in the human world.]]
* IgnoredEpiphany: He sees [[spoiler: fragments of Zatch's memories, revealing bits of Zatch's past along with the horrific might of Bao.]] He seemingly shrugs it off [[spoiler: though he eventually realizes he was in the wrong. Furthermore, he confessed that if he did win, he would've destroyed Zatch's book to prevent Bao from consuming him.]]
* KickTheDog: Beating Rops was all part of the competition, but he rubs it in by having Dufort Zeker the already burning book, destroying it instantly so Rops doesn't have the chance to give his bookkeeper a farewell.
* MyGodWhatHaveIDone: [[spoiler:Starts undergoing one when he catches a glimpse of Zatch's memories and seeing the corrupted form of Bao. Finally hits it when defeated and sees Zatch's unpleasant past. Sums it up as such: "Forgive me, Zatch. Your brother has been a fool."]]
* PetTheDog: Seeing [[spoiler: Rodeaux]] being willing to risk his life to attack him, Zeon tanks the hit rather than dodge it.
* ThePowerOfHate: His suffering along with the hate from Dufort resulted in his ultimate spell. [[spoiler: He and Dufort were released from it when Bao ate the spell.]]
* ShockAndAwe: Just like Zatch, although he's far more competent with it.
* SlasherSmile: He's very prone to making crazy grins.
* SmugSuper: Fond of using only the bare minimum of force to counter his enemies' spells. This still comes off as him showing off though, since he's beating them with spells that ought to be much weaker than theirs.
* TykeBomb: Trained from when he was ''three'' to be a candidate for king.
* WhenHeSmiles: [[spoiler: During the last clash between his ultimate spell and Bao Zakeruga, he witnesses Dufort shedding tears from Zatch taking in his hatred and suffering... and cracks the first genuine, warm smile in the series from his debut up to that point.]]
* WhiteHairBlackHeart: His white hair is infamous among the other children, along with his ruthlessness and malevolence.
* YouCannotGraspTheTrueForm: Of Baou Zakeruga. Not until he sees [[spoiler: Zatch and Kiyo nearly devoured by its power]], he doesn't.

!!!'''Voiced by:''' Creator/HikaruMidorikawa (JP), Creator/DaveWittenberg (EN)
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/0dufort.png]]
Zeno's partner, a mysterious, quiet young man of unknown ethnicity. His stoic demeanor hides incredible intellect and intense hatred.
----
* AdmiringTheAbomination: He admits that Faudo's power fascinates him, and that he doesn't really care about the collateral damage as long as he gets to see it in action.
* AskAStupidQuestion: Given his Answer Talker power, asking him how he knows something causes him to respond with derision.
* AwesomenessByAnalysis: His Answer Talker ability; anything he can observe, he can answer any question about as fast as blinking.
* BlueAndOrangeMorality: He considers the lives of human beings to have no more importance than the lives of flies. Since no one cares if a fly dies, he figures it doesn't matter if people die. He admits that most people would probably disagree with his assessment. He ends up [[spoiler: moving past this, first as a favor to Zeno and later the experience in his travels being shown gratitude moves him.]]
* DeathActivatedSuperpower: Implied. He states that the Answer Talker comes from dying then coming back to life.
* DeathSeeker: He's enough of one that Zeno's parting words to him are a demand that he live on and not just throw his life away because living is too troublesome. Dufort later gives his reason for living being him keeping a promise to friend, indicating this wasn't an unnecessary gesture either.
* FreudianExcuse: [[spoiler: Dufort was raised in a lab environment from childhood, treated cruelly and anyone kind to him was removed. After years of torment and testing, he was given one final battery of tests that opened the path to his release, all while taunted by the scientist who had ruled his life. Turns out that A) His Answer Talker was being used for military application, B) He was being released into the Arctic to die rather than being freed, and, oh, C) His mother sold him for ten thousand dollars.]] Teaming up with Zeno doesn't seem so far-fetched, considering...
* HeelFaceTurn: [[spoiler:After traveling the world for a little while after Zeno's defeat, he chooses to come back to help Zatch and co. defeat Clear. By using his Answer Talker abilities, he is able to coach each one in what they need to do to get stronger during the 10 month period that Clear was recovering from their previous battle.]]
* HumanizingTears: [[spoiler: When Zatch through Bao takes in his hatred and suffering, crying for him, it ends up making him tear up at the first real sign of compassion. After curing a child in an African village and being showered in gratitude, the display of positive emotion and care moves him deeply, causing him to cry again.]]
* MentorArchetype: [[spoiler:During the Clear Note arc, he helps the remaining MainCharacters bring out their greatest potential via his use of the Answer Talker. He also trains Kiyomaro to stabilize his own Answer Talker ability so that he can use it on demand.]]
* MisanthropeSupreme: Implied during his fight with Apollo, and later confirmed when he and Kiyo finally meet. Kiyo attempts to appeal to him to stop Faudo, but Dufort shrugs it off, rather bluntly saying that he sees no value whatsoever in human life.
* NervesOfSteel: He jumps off a pillar at least three stories tall without flinching, confident Zeno will catch him.
* NoSocialSkills: He's very bad at even carrying on a conversation. Justified, seeing as the only human interaction he's had was through a computer screen.
* NotSoDifferentRemark: With Kiyo Takamine, in the Anime when he mind scans the former commenting about his years of jealousy-fueled neglect received both from his peers and his teachers in life, comparing it to his own harsh lab rat days in the asylum he'd been incarcerated in.
* NotSoStoic:
** Was angered so much when Apollo asked how much hatred he was hiding to the point where he attempted to finish him and Rops off with Zeno's ultimate spell, until Zeno convinced him otherwise.
** [[spoiler: Is moved to tears when he sees Zatch taking in his suffering to free him from it]].
** [[spoiler: He ends up in tears again when the family who's child he cures shows him gratitude. The emotional experience moves him deeply and being shown genuine care makes him weep once more.]]
* ThePowerOfHate: His Answer Talker ability was honed through pure hatred. It's implied his immense amount of heart power comes from this hatred as well. [[spoiler:He loses this thanks to Zatch and Bao.]]
* PsychicPowers: In the anime, Dufort had vast psychic powers for which he was poked and prodded within an undisclosed facility for most of his life.
* ShadowArchetype: Dufort is exactly the kind of person that Kiyo would have become had it not been for Zatch. Dufort's nihilism and misanthropy is a darker reflection of Kiyo's BystanderSyndrome and hatred of others before his character development. Dufort's hatred-fueled Answer Talker ability is also a mirror to Kiyo's [[AwesomeByAnalysis genius level intellect]]. And Zeno's influence on him is the polar opposite of Zatch's influence on Kiyo. The anime is a lot more direct about this.
* SkewedPriorities. He cures a child's fatal disease because the boy's family's wailing was keeping him from getting any sleep.
* TheStoic: He's rarely seen with so much as a twitch.
%%* StrawNihilist: Given his past, it's no surprise. [[spoiler: CharacterDevelopment frees him from this.]]
* SuperIntelligence: Dufort possesses a psychic ability known as "Answer Talker", which allows the user to immediately know the answer to any question. This lets him instantly calculate the best winning strategy for any situation.
* VillainousFriendship: He and Zeno are as close, if not closer, than Zatch and Kiyo. Dufort goes so far as to call Zeno his brother in one of the only genuine displays of warmth he ever shows.
* WalkingTheEarth: [[spoiler: After Zeno's gone, he decides to wander and look for a new purpose.]]

A male Mamodo adolescent resembling a cross between a lion and a centaur, and the second major villain that Zatch faced. Ruthless in his determination to become king, Riou sought to use Faudo to overcome all other demons. His magic shapes his energy into beasts.
----
* AintTooProudToBeg: It kills him to say it, but he virtually begs Kiyo to fix his tampering with Faudo's systems. Kiyo is having none of it.
* AnimalMotif: Lions. His spells also have a beast theme.
* ApeShallNeverKillApe: [[spoiler:He (tries to) kill Kiyo but is content with burning Zatch's book.]]
* ArcVillain: Of the Faudo Arc. At least at first.
* ArchEnemy: Comes to view Kiyo as his main enemy out of everyone opposing him. Kiyo in particular draws his ire for successfully outsmarting Leo at every turn and sufficiently tampering with Faudo's system to prevent Leo from using the giant demon the way he intended.
* CastFromHitPoints: [[spoiler: His curse hurts him just as much as it hurts the victims.]]
* ClownCar: His partner Banikis is inside the ''mouth on his chest''.
* DangerousForbiddenTechnique: His final spell turns him into a giant berserk beast, which he avoids using because he can't distinguish friend from foe in the form and is therefore a danger to his bookkeeper. [[spoiler:He's ''still'' no match for Zeno.]]
* DeadpanSnarker: Banikis, in the manga, mostly at Riou's expense.
* EvenEvilHasStandards: [[spoiler: Having been [[HijackedByGanon beaten by Zeno]], Leo gloats to him that his goal to take over Faudo is a futile one, as he's armed a failsafe device that will send Faudo back to the Mamodo World. Zeno simply smirks and says he'll just wreck the device then, visibly horrifying Leo - he'd intended to use Faudo to win the tournament, not destroy the world, which leaving him in the human realm would inevitably do. Not that he's in any position to argue, as Zeno immediately sends him back]].
* EvilIsPetty: He sets Faudo to attack Japan, even knowing he has barely enough time to do so before Faudo is sent back to the demon world, just to spite Kiyo.
* ForTheEvulz: He attacks Kiyo with repeated small spells rather than hitting him with a big one and killing him instantly, because he wanted to make Kiyo suffer.
* HeroKiller: [[spoiler: Kills Kiyo, temporarily.]]
* HijackedByGanon [[spoiler: Mid-way through the Faudo Arc, Zeno takes over and sends Riou back to the mamodo world]]
* UnstoppableRage: Aforementioned final spell.
* WellDoneSonGuy: We find out in flashback that everything he did was due to the pressure of representing his family in the tournament, and he was seriously conflicted about some of the things he did.
* WorfEffect: Defeats Zatch and Kiyo, then is beaten by Zeno to show how dangerous the latter is.

!!Clear Note and Vino
[[folder:Clear Note]]
!!!'''Spell Specialization:''' Annihilation
[[quoteright:228:https://static.tvtropes.org/pmwiki/pub/images/clear_note.png]]
Clear Note is a male humanoid Mamodo adolescent, and the final major villain that Zatch faced. Ruthlessly powerful, he aspired to use the power he would claim as king to kill every demon in existence. He boasts the ability of Annihilation, which allows him to completely nullify all spells and creates pockets of NegativeSpaceWedgie where he chooses.
----
* AdaptedOut: He and Vino don't appear in the anime.
* AntiMagic: The ''Supurifo'' spell family has the ability to completely negate a spell's effect within a given area.
* ArcVillain: He's the villain of the last arc.
* BadPowersBadPeople: An OmnicidalManiac with the power of annhiliation. [[spoiler:It's eventually revealed his desire to destroy comes from having those powers. When ''Shin Clear Seunousu's'' core is destroyed, Clear is reborn without any of his villainous traits.]]
* {{BFG}}: The ''Zarefedōra'' spell creates a gigantic artillery cannon which ''doubles as a projectile''.
* BishonenLine: Played straight with first, then averted with his OneWingedAngel form.
* BloodKnight: He likes to fight, expressing satisfaction when Zatch manages to challenge him and lamenting that his rivalry with Ashuron is ending. [[spoiler:That he doesn't feel this way during the second battle against him is the first sign that his personality is almost fully overwritten by Shin Kuria.]]
* BrainwashedAndCrazy: At the final battle, everyone acknowledges that Vino appears to be under Clear's control. Whether he was always like that is unclear, but it's worth noting that he goes back to being a regular baby once Clear is defeated. Brago also notes that Clear himself may be subject to this, his personality slowly being warped and destroyed by his own spell, the Shin Kuria.
* CombatPragmatist: He's not above using his enemies as human shields and though he admits it's a little lame he's fully willing to simply dodge Ashuron's final all or nothing attack.
* CreepyChild: All Mamodo are children, but Clear Note looks the most human of them all. That's not even getting to the effect he has on Vino, which makes him one, too, as he has a dull dead-eyed look.
* DemBones: The ''Bādorerugo'' spell conjures a giant, white, winged doll, which looks like a dragon skeleton.
* DiabolusExNihilo: Clear gets not a single mention prior to the arc where he's front and center, and promptly shows up to wreak havoc, establishing himself as the strongest demon in the series yet and the final antagonist, with the ultimate goal of erasing all demons from existence - himself included. None of the other demons seem to know anything about him, and no mention is made of his past or reason for being outside of that he is "the power to destroy". Little is said about Vino either, the talking human infant that is his bookmaster.
* EvilutionaryBiologist: He claims his existence and intentions to be the natural result of Mamodo evolution.
* GenericDoomsdayVillain: He's an extremist nihilist whose goals are the destruction of the human and Mamodo worlds and then suicide. He's also [[DiabolusExNihilo never so much as mentioned prior to his arc]].
* InvincibleVillain: His first appearance; he hands Brago his first and only [[spoiler:non-friendly]] defeat, destroys the full-power Baou Zakeruga, and nobody but Ashuron is able to lay so much as a finger on him (Brago pitched in at one critical moment, but only because Vino was out of energy). Interestingly enough, the fights with his various powered-up forms are much more even thanks to the heroes also getting much stronger.
* KillingIntent: His murderous intent manifests as a malevolent, demonic aura. It is so potent, he was able to scare both Brago and Sherry.
* LackOfEmpathy: Using Answer Talker, Dufaux in the Gash Cafe identifies Clear as someone who was born without the concept of love, utterly incapable of understanding it now or in the future. Clear only grasps through secondhand knowledge that the reason people don't destroy things is because they love them - Clear himself feels zero qualms about eradicating all demons because he can't comprehend shared positive emotions with anyone else besides himself.
* LightIsNotGood: Pure white, and pure evil.
* NoSell: The ''Supurifo'' spell family, as mentioned above. Unlike other defensive spells, they don't stop attacks as much as they directly cancel their effects or make them disappear.
* MeaningfulName: The name "Clear Note" can refer to his spellbook being a clear note(book), reflecting his complete lack of humanity and empathy, as well as the clarity of his intent, which is free of emotional attachment. "Clear" can also refer to "nuclear" as in nuclear weapons, which he compares himself to. His most powerful spell appropriately has his name in it, being called Shin Kuria(Clear) Seunousu.
* {{Nonanswer}}: After being asked why he's going to kill all the Mamodo, he replies that he wants to kill all the Mamodo. Though he elaborates more, his reason still boil down to him thinking his purpose in life is to kill.
* NonstandardCharacterDesign: Though the Mamodo in general have highly varied designs, Clear sticks out for his highly humanoid appearance - being virtually indistinguishable from a human teenager, and dressing the part too. This only serves to emphasize his nature as an eerie, unsettling force, even amongst demons.
* NoodleIncident: How did Clear get a baby as a bookkeeper is anyone's guess. We don't know what happened to Vino's parents either.
%%* OmnicidalManiac: To its [[DeathSeeker logical extreme.]]
* OneWingedAngel: Ends up with two such forms, each giving him an ungodly amount of power.
* OutsideContextProblem: A supremely powerful demon of unknown origin who shows up near the very end of the series, with the stated goal of not just winning the Mamodo battle, but eradicating the entire Demon World. For whatever reason, not even Zeno or any of the Bells were aware of his existence until he actually made himself known.
* ParentalAbandonment: States in the Gash Cafe that he never knew his parents, though [[MultipleChoicePast whether he killed them or whether they simply left him, he's not sure.]]
* PersonOfMassDestruction: He compares himself to a nuke.
* PhysicalGod: His final form ends up this way.
* PoweredByAForsakenChild: [[spoiler:We never find out anything about Vino, the baby who wields Clear Note's spellbook]].
%%* PowerOfTheVoid: The ''Radisu'' spell family.
* PureIsNotGood: It's implied that the reason he's so powerful is that his bookkeeper is a baby and can thus supply completely "pure" heart energy.
* RecursiveAmmo: ''Bādorerugo'' can shoot its hands which separate into smaller parts. Every tiny part contains the Annihilation effect of the ''Radisu'' spell family.
* {{Reincarnation}}: Baou's ability to erase evil appears to mean this for him. [[spoiler:When Clear got ripped apart by Baou, it stripped him of his old memories and personality, and even his appearance, bringing him back as a ditzy young child named White.]]
* TheRival: He considers Ashuron this. [[spoiler:To the extent that even after being controlled by Shin Kuria, he still recognizes one of Ashuron's spells, to the dragon's surprise.]]
* SensorCharacter: His ability to sense other demons is unsurpassed as his range goes up to 5,000 km.
* ShadowArchetype: He is considered one to Zatch. Both of their strongest spells are revealed to have sentience. The main difference is that Zatch was able to overcome the corruption of Baou and even pacify it. Clear Note fell pray to his own power and is being used as a puppet by his most powerful spell. He is basically the kind of person Zatch could've become if he were consumed by Baou.
* SoLastSeason: Does this to his predecessors as BigBad by virtue of his methods: he ''kills'' his opponents. As nasty as they were, even Zeno and Zofis were simply content to send them back, but not Clear.
* TheSociopath: The ''Gash Cafe'' special implies that Clear is simply incapable of feeling ordinary emotions, and can only derive pleasure from destroying things.
* VillainForgotToLevelGrind: An aversion. Clear is implied to have gotten stronger between his bouts with Ashuron and explicitly takes the time while recovering from Ashuron's attack to further empower himself.
%%* WhiteHairBlackHeart
* WithGreatPowerComesGreatInsanity: [[spoiler:His current looks, goal and power level comes from him being controlled by his own spell, ''Shin Clear Seunousu'']].
* TheWorfEffect: Delivers Brago the only one of these he ever gets. Brago, after training, returns the favor to his first OneWingedAngel form.

----
* BrainyBaby: Vino seems to be pretty smart for baby, considering that babies normally can't read or talk in complete sentences like older kids. It's hard to tell if this is because of Clear's influence or what, though it's implied he's this because of Clear.
* GooGooGodlike: Vino has a large amount of heart power. We can guess this is probably why Clear chose him to be his bookkeeper.

!!!'''Spell Specialization:''' [[AnIcePerson Ice]]
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/reycom.png]]
A male 8-year-old humanoid Mamodo and the first (second in the anime) enemy that Zatch faced in the battle. His cool, quiet, and laid-back to the point of fault demeanor hides a malicious core that thrives on abuse and wickedness to become stronger.
----
* BlueMeansCold: He has blue hair and his outfit consists of a dark blue shirt with white patches that give the blue a cross design on the front and back and a large silver snowflake in the center of the shirt. His spells allow him to shoot ice out of his mouth.
* EvilCounterpart: His relationship with Hosokawa is a negative contrast to Zatch and Kiyo's early relationship with each other. Kiyo tends to think of Zatch as an annoyance, but still tries to look out for him. Hosokawa thinks Reycom's the best thing that ever happened to him, but still treats him like dirt. And while Zatch is working to make Kiyo a better person, Reycom encourages Hosokawa's descent into villainy to make himself more powerful. On a related note, Reycom's book is blue to Zatch's red.
* AnIcePerson: Reycom's basic spell, Gikor, shoots massive icicles out of his mouth. His second spell, Freezudo, freezes things in ice.
* PoorCommunicationKills: Almost literally. Reycom's book is burned because Hosokawa sought out Zatch to steal his book and use him as well, something Reycom knows is impossible but apparently never mentioned.
* SmallRoleBigImpact: He only appears for a few chapters in the manga, around two episodes in the anime, and is never seen again after his book is burned (except for a cameo in one of the last chapters). However, his actions establish a great deal of the Mamodo Battle and how it works. Kiyo and Zatch had no idea there were more kids like Zatch until confronted by Reycom and Hosokawa in the manga, and it's through fighting them that they learn spellbooks only work for one person, and the Mamodo disappears when their book is burned. The fight also marks the first use of the second spell, Rashield, and when Zatch realizes that the magic is coming from him, as before he thought it was Kiyo's tricks and strategies.
* StarterVillain: He only knows two spells, freely admits he and Hosokawa are only using each other, doesn't work with him at all and is unrelated to any future characters or story arcs. Reycom and Hosokawa are the only team to attack Zatch for reasons ''other'' than to burn his book and become king. But they are the first team Zatch and Kiyo defeat on their path to make Zatch king -- even if, at this point, they don't know it yet.

Reycom's human partner. He's a middle-aged man who went mad with power when he discovered Reycom's abilities, using him to do whatever he wanted while treating him as no more than a tool. He never learned, nor did Reycom tell him, of the demon battle and what he was.
----
* AdaptationDeviation: In the manga, Hosokawa learns about Zatch when he and Kiyo foil some bank robbers. In the anime adaptation, he ''is'' the bank robber.
* LockedOutOfTheLoop: Hosokawa has ''no idea'' what Mamodo are, or of the contest to become king. He didn't even know there were other kids like Reycom until he reads about Zatch in the newspaper -- or when he and Kiyo thwart his bank robbery in the anime -- and then tries to take Zatch and his spellbook, not knowing [[OnlyTheChosenMayWield only the chosen partner can use it.]] This despite the fact that he's been working with Reycom for a while now, who ought to know all this. Apparently, [[YouDidntAsk Reycom just never bothered to tell him anything.]]
* PunchAWall: He does this after getting fired from his job.
* UngratefulBastard: Hosokawa was a poor delivery man who hated his job before meeting Reycom, and used the demon to better himself and take revenge on people he didn't like. Despite that, he sees Reycom as nothing but a tool. When Kiyo furiously points out that Hosokawa is wearing a nice suit while Reycom looks like he just crawled out of a dumpster, Hosokawa just laughs.

[[quoteright:174:https://static.tvtropes.org/pmwiki/pub/images/0hyde.png]]
A male 8-year-old humanoid Mamodo child. Not evil, but ambitious to claim the throne of king and with few regards for the consequences of his actions. He appeared in the anime as the first antagonist that Zatch faced, clashing a couple of times but neither winning or losing.
----
* BlowYouAway: Hyde's spells are wind-based. Jikir is a strong gust of wind, and Jikirga is a concentrated wind blast.
* CanonImmigrant: He and Eido started off as anime-only filler characters with barely two appearances, but apparently were memorable enough that the author ended up including Hyde as one of the Mamodo who helps Zatch in the FinalBattle (thereby confirming that he and presumably Eido were part of the battle to become king) and later in a group photo in the Mamodo world school. They even appeared in the official series calendar in 2007 despite being the only non-plot relevant characters to do so.
* FillerVillain: What he started off as, which was probably a big reason why he and Eido were never seen again shortly after their second appearance. Makoto Raiku would later stealthily include Hyde [[CanonImmigrant in the manga]], albeit only in cameos in the last few chapters.
* MinorMajorCharacter: He's the first villain in the anime and forms one of the few teams which Zatch and Kiyo could not defeat, and also gets an interesting bit of CharacterDevelopment with Eido in their second and last episode, all of which appeared to set the two as important {{Foil}}s to the protagonists in the future. However, after a mere cameo in one of Megumi's concerts, they never appear again in the series.
* SuperpowerLottery: He somehow has powerful wind-related skills that are ''not'' spells, such as making himself and Eido fly around or teleport away in a gust of wind.

----
* BullyMagnet: Hyde first finds Eido when he's being picked on by bullies.
* CoolBoard: Eido likes riding his skateboard while using Hyde's wind spells to fly, though Hyde says it just makes him look like a poser.
* DidntThinkThisThrough: Eido kidnaps Zach and Kiyo's friends to force a confrontation with the pair. Unfortunately, he forgot to tell them ''where to go'' in the note he sent. His own captives berate him for how stupid that was.

----
* BrainwashedAndCrazy: Given Gofure starts trembling and whining when Renji arrived and stopped after a spell was cast, it's likely he also had a forced personality change like Kolulu. The ''Gash Cafe'' special contradicts this, suggesting that Gofure has a somewhat sadistic personality even when not transformed.

This decision would ultimately backfire on the duo however, as choosing an abandoned building filled with metal proves to be just what their foes need to end the battle in their favor. Afterwards, Fein's book is burnt while he is still restrained by Zatch and Kiyo's newest spell.
----
* BlowYouAway: Fein can manipulate and control wind as his primary form of attack.
* FragileSpeedster: Fein has a powerful spell that lets him move so fast he at first appears to be teleporting when he uses it. The tradeoff is that because his body is so weak and tiny he ends up getting effortlessly pinned down by heavy metal debris when hit by a single Jikerdor spell, ending the battle in his defeat.

* DishingOutDirt: All of Eshros spells are earth based.
* ManipulativeBastard: Eshros uses Shin's dead mother to motivate him to do his bidding, telling him that she'd be disappointed if he didn't do what he said. This comes back to bite him on the ass when Shin gets tired of putting up with his crap.

* GentleGiant: Despite his large physique, Shin is a selfless, kind, gentle, altruistic, and unassertive man.
* MistreatmentInducedBetrayal: Eshros' manipuation of Shin causes the latter to soon realize just what a vile and cruel kid he truly is, promising to burn his own book himself to prevent him from hurting anyone else.

A male 10-year-old Mamodo who was a close friend of Tia's back in the Mamodo world but quickly turned against her during their first encounter in the human world. Knowing that she hadn't yet found her human partner and was completely defenseless he attacked her and tried to elimate her from the battle to become king right then and there. Luckily, Tia survived his betrayal and soon partnered up with her friend Megumi and later Kiyo and and Zatch to finish the fight against him once and for all. After an intense battle with the two newly allied teams he got his book burnt with one final Zaker attack that sent him back to the Mamodo world for good. His partner was a middle aged man in a white suit named Rembrant.
----
* DramaticallyMissingThePoint: He turns on Tia because, as the contest can only have one winner, every other Mamodo is his enemy. Though only one Mamodo can win, cooperation is vital to gaining an edge and every major player in the battle, even the strongest Mamodo, has at least one or two allies. In fact, the structure of the contest pairing every Mamodo with a human partner suggests that the eventual king being able to team up and collaberate with others was part of the point of the battle.
* ExtraOreDinary: His spells allowed him to summon powerful metal weapons like spiked metal balls or even a giant drill.
* FalseFriend: Tia considered him to be one of her closest friends while the two were still in the Mamodo world. It isn't long before he shows his true colors though, with a nearly successful attack that leaves her wounded and with severe trust issues. Shocked and deeply hurt by his betrayal, she takes a while to fully recover from the physical and emotional pain he inflicted on her.
* {{Foil}}: He is one to Gash in relation to Tia. While in the Mamodo world he pretended to be nice and friendly to Tia, but he discarded all of that once he contest began and targeted Tia specifically because he thought she would be an easy target. Meanwhile, despite Gash knowing nothing of Tia from before he lost his memories, he immediatly jumps to protect Tia and defend Megumi's concert. Likewhise, despite his amnesia, Tia observes Gash is still the same person in practice, defending others despite the danger, in contrast to how much Maruss changed when arriving in the human world.
* KickTheDog: He announces that after defeating Tia, he'll attack and ruin Megumi's concert purely to spite Tia.
* TheSocialDarwinist: A firm believer in this, which is why he betrayed Tia. It's also why he's angry when Zatch is able to beat him, since it basically deconstructs his whole philosophy.
* SoreLoser: Maruss is FURIOUS when Zatch is able to surpass him.
* ThisIsADrill: His ace spell Gigano Garanzu summons a massive spinning drill to attack the opponent with.
* TrademarkFavoriteFood: Maruss likes fish, korokke, and tulips.
* UnskilledButStrong: His spells tend to lack subtlety and utility but make up for it with sheer raw power.

It turns out to have been all a clever trap to force Kiyo and Zatch to fight them at a severe disadvantage due to the cold and allow Robnos to make full use of his laser beam and duplication abilities. After temporarily disabling one of the Robnos twins with a Jikerdor spell the two then fuse into their ultimate form for the final stretch of the battle. Seemingly outmatched and outginned against such a powerful opponet a bit of quick thinking from Kiyo saves the day and Robnos is sent packing back to the Mamodo world. As for Suzy... she was never captured by the duo to begin with, just out sick.
----
* CoolHelmet: It's actually a huge factor in his defeat. Kiyo was able to correctly guess that his attacks required him to build up power in his helmet before firing and used a metal pole to turn him into a giant lightning rod.
* EyeBeams: Robnos' most basic spell is a simple laser beam fired from his eye. Unfortunately, the location of the battle allows him to reflect it off of multiple surfaces to hit his target, making for a surprisingly dangerous basic attack.
* FusionDance: There are actually two seperate Robnos at the beginning of the battle that combine their attacks to hit Kiyo and Zatch whenever they try to dodge one of their laser beams. After the second one is captured by Jikerdor, Ruku uses a spell that lets them combine into a single more powerful entity.
* NoSell: Subverted. He pretends this happened with Zatch's Zaker spell, but Kiyo realizes that wouldn't have prevented his clothes from being burnt and figures out that he switched himself with another, unburnt copy.

After their battle with Zatch and Kiyo starts going south, he and his partner decide to make a quick escape and flee while the castle crumbles to the ground around them.

A 7-year-old lizard Mamodo, originally teamed up with Papipurio and Lupa before their lack of teamwork caused them to go their separate ways. Zoboron is a silent female Mamodo that resembles an iguana and with her partner Hige, they fought against the protagonists at the amusment park and actually had them on the ropes for a bit with their combo attacks before a fight between them ends their partnership. At the end of the battle their spellbook gets burned and Zoboron gets sent back to the Mamodo world, leaving Hige to desperately try to rejoin with Papipurio & Lupa as they make their escape.
----
* KillerRabbit: Zoboron looks like an ordinary harmless iguana and can fire out massive energy blasts that wouldn't be out of place in a series like DBZ.
* UnskilledButStrong: A variation; Zoboron's spells are extremely powerful, but just as easy to dodge. Not helping matters is that Hige is remarkably stupid, and therefore incapable of mitigating this handicap with strategy.

* DirtyCoward: He uses Papipurio as a HumanShield to absorb attacks, which infuriates his partner Lupa.

A male 8-year-old humanoid Mamodo dressed like a prince. A comparatively weak demon who survived by laying low and repeatedly partnering with other demons. Cowardly and something of a spoiled brat, but with a good heart beneath it all. His spells are more disruptive than destructive, but not to be underestimated.
----
* AffablyEvil: Despite how much he and Lupa antagonized Gash and the others in their past battles and involving themselves in resurrecting Faudo, they were never really evil in the first place, [[HeelFaceTurn and they eventually lose their selfish attitude after being saved by Kanchome.]]
* BornLucky: Manages to [[spoiler: get into the last ten demons]] despite being absurdly weak.
* DidntThinkThisThrough: He and Lupa plan to hide out in a bomb shelter until all the other Mamodo eliminate each other and leave no competition for Papipurio to become king. How they expect to defeat the last Mamodo left, who has defeated all the others, is never explained.

A female 7-year-old humanoid Mamodo and one of Zatch's friends. She has an obsessive one-sided crush on Zatch, and misplaced anger led her to serve Zofis in the battle. Very vain, but not without conscience. Her spells are Water-based.
----
* AdaptationDyeJob: In the illustrations on the covers of the manga, her hair is a pinkish white color, but in the anime, it is turquoise. Also, her crown hair accessories are blue in the manga, while they're yellow in the anime.
* AnimalMotifs: Her twintails are styled to resemble rabbit ears and her dress has a white ball attached to the back of the waist, mimicking a rabbit's tail.
* BitchInSheepsClothing: She's extremely cute and sweet at first glance, but beneath that face, she's ''extremely'' selfish, vain, and ultimately just unpleasant.
* CuteAndPsycho: At first, she comes off as sweet and nice, if vain. Once she learns Zatch doesn't remember her, however, she turns into a rabid lunatic.
* DistaffCounterpart: To Zatch. When she cuts off her hair in the Millennial Demon Arc, she looks almost exactly like him. Many of their spells mirror each other as well, most notably "So Giaku" and "Baou Zakeruga."
* ElementalBarrier: She can create a shield made from water that can also absorb electrical attacks.
* ElementalEyeColors: She's a blue-eyed water user.
* ElementalHairColors: The anime gives her blueish hair to match her water element.
* EntitledToHaveYou: She's absolutely convinced that Zatch owes her reciprocating her feelings because she has been obsessed with him since the first time she saw him. In her mind, Zatch accepting fish from her is undeniable proof that he's her boyfriend. She finds it extremely insulting that Zatch forgot about her, even though he has amnesia and she never made that much of an impression on him regardless of that.
* EvilIsPetty: She joins in with Zofis simply because Zatch doesn't remember her in the Demon World despite the fact he lost his memory, finding it unforgivable that he forgot about her regardless of the reason. Kiyo tried to explain this to her, but due to some [[PoorCommunicationKills bad communication from Zatch]], it just makes Penny think she's being taken advantage of.
* GirlishPigtails: She's a very immature brat with her hair styled in two pigtails pointed upwards.
* GoofyPrintUnderwear: Her panties have an image of Zatch's face.
* HeelFaceTurn: In the Ancient Mamodo Arc. [[ArmorPiercingQuestion After Zatch demands to know if Penny is aware of how awful she's treated the other Ancient Mamodos and their brainwashed human partners, along with all the other terrible things she's done]], Penny tries to redeem herself by helping defeat Demolt and destroy the Moonlight Stone with Byonko and Alvin. It's also the first time Uri actively helps her instead of just following orders, as she's doing something noble for once, even giving Penny orders instead of the other way around, to which she agrees.
* HeroicSacrifice: Catches Demolt's attention so he would attack her instead of Ururu. [[spoiler:Zatch and Ponygon keep her from dying, although her book is still burned.]]
* ImportantHaircut: She cuts her pigtails off to use in distracting Demolt, cementing her HeelFaceTurn. The grand finale shows she keeps the shorter hairstyle.
* ItsAllAboutMe: She only cares about what she wants and throws a fit when things don't go her way. During a flashback of their early adventures together, Penny made Uri sound like an UngratefulBastard when he was trying to warn her about how selfish her actions were, even outright stating that he was starving for food ''and'' work before Penny met him, and is now able to eat three meals a day because of her. It isn't until the battle with Demolt that Uri finally gets through to Penny about how her selfishness won't be enough to either defeat Demolt or destroy the Moonlight Stone, leading Penny to realize that she also needs to follow orders from Uri in order to work together and accomplish their goal.
* KickingAssInAllHerFinery: She always wears a blue PimpedOutDress, even when she goes into battle.
* LittleMissBadass: In their first battle, the small Penny was actually kicking Zatch's butt for a good portion of the fight.
* LoveAtFirstSight: She was smitten with Zatch while watching him wrangle a fish from her private beach.
* MakingASplash: All her spells revolve around the power of Water, which she can use to absorb Gash's Lightning powers and send it right back at him, proving her powers to easily counter his. Of course, after her HeelFaceTurn, she and Gash's powers combine to fight against Demolt in order to help destroy the Moonlight Stone.
* NightmareFace: She puts on a pretty nasty face whenever something or someone sets her off.
* NotGoodWithRejection: Anytime Zatch doesn't recall her or rejects her feelings is all she needs to go off the deep end.
* PetTheDog: Though she was ''totally'' selfish and committed illegal acts in order to do so, her helping provide for Ururu's family ''was'' pretty nice of her.
* PrincessPhase: She dresses like a fairy tale princess and dreams of marrying a prince [[spoiler:which is why she's so obsessed with Zatch.]]
* PuppyLove: She's a 7-year-old kid with a big crush on Zatch, who is only a year younger than her.
* SelfProclaimedLoveInterest: Inside her head, she's Zatch's girlfriend, but in reality, she was just a [[StalkerWithACrush stalker]] and had no real interaction with him besides her giving him a fish as a present. Whether or not he had amnesia, asking him to remember her would have probably been pointless.
* ShapingYourAttacks: Her strongest spell creates a huge dragon of water to attack her foe.
* SpoiledBrat: It's implied that her parents are rich, since she has her own private beach in the Mamodo World, which would help explain why she ended so self-centered and self-entitled.
* StalkerWithACrush: No matter how much she sugarcoats it to make it seem like she was Zatch's girlfriend, it is pretty obvious in flashbacks that she was just an obsessed stalker who deluded herself into thinking Zatch liked her because he accepted a fish from her.
* SweetTooth: She loves sweets in particular.
* ThirdPersonPerson: In the original Japanese, she refers to herself in the third person, calling herself "Patie-sama".
* TinyTyrannicalGirl: Her dynamic with Uri is basically her bossing him around and having him fulfill her every whim because she knows he can't say no to the one who is keep him afloat.
* TookALevelInKindness: She starts as an absolutely selfish, entitled, and petty brat, but becomes nicer after her HeelFaceTurn.
* TrueBlueFemininity: She's a very feminine girl who always wears a blue dress.
%%* {{Tsundere}}: Towards Byonko.
* WaterIsWomanly: A young girl who likes pretty things, has obsessive romantic feelings for Zatch, and wears a blue dress. She uses water spells, one of which forms a huge dragon made of water.
* WomanScorned: She feels scorned by Zatch because he forgot about her, even though that's Zeno's fault, and makes it her main goal to make him pay for hurting her feelings, even joining Zofis' side to get back at him.
* {{Yandere}}: She has an obsessive crush on Zatch and goes ''livid'' when he admits he can't remember her (because of his amnesia), swearing to burn his book for forgetting his "true love".

A male 6-year-old Mamodo resembling a frog, he was a loyal servant to Zofis. Childish, naïve, and annoyingly persistent, he wants nothing more than friends to play with.

* BigDamnHeroes: Double-subverted. He tries to come from out of nowhere to save Patty from Zatch's Baou Zakeruga, but forgot that Alvin wasn't there to actually cast any of his spells and he gets blasted alongside her. Still, there being two targets instead of one diffuses Baou's power enough that they both survive. Played straight after his HeelFaceTurn.
* CrouchingMoronHiddenBadass: Byonko is pretty much a joke. He only ever shows up to get his ass kicked and Alvin doesn't read the spells to help him. But once he does, the first thing Byonko does is knock ''Demolt'' on his ass.
* EndearinglyDorky: Alvin promised to give him a cookie at three o'clock, so Byonko made a fake clock set at that time. It was stupid and cute enough to convince Alvin to participate in the battle to become king.

Cool, calculating, and vindictive to those who wrong him, yet despite his enhanced sight, he experienced tunnel vision when it came to his goals. His power over shadows makes him a formidable foe.
----
* AlasPoorVillain: As his book burns, he laments that he wasn't friends with Leo and that after all their hard work, the grand vision they once had was stolen from them with ease by Zeno. His last act is to apologize to his partner for being a handful.
* AntiVillain: Despite what he says, he's really only in it to help Leo.
* DeathGlare: Gives one to Fango. An omake panel reveals he was absolutely ''seething'' despite his apparent composure.

* TeethClenchedTeamwork: He and Fango are all but attacking each other despite being on the same side.
* TragicVillain: After Leo is defeated, all he had left was a pointless grudge against Alishie. Alishie recognized how empty he was and pitied him.
* UnfriendlyFire: Fango clips him with one of his spells, badly burning Zaruchim's arm.
* VillainousBSOD: Aleshie sent him into one when they first met. After looking into his eyes Zaruchim was left frozen and trembling. Avenging that humiliation is a major motivator for him.
* VillainousFriendship: Leo's defeat pretty much kills his drive. He later laments that he wasn't even friends with Leo, but it's unclear if he's in denial or sad that their businesslike relationship wasn't more personal.
* WorthyOpponent: His treatment of Riya and Aleshie, especially Aleshie, is an odd case. The gist of it is that he considers them to be this trope, but can't bring himself to admit it, and therefore wants to crush and humiliate them to prove he's the better fighter.

* {{Foil}}: Keith to Bari. They're both powerful combatants with polar opposite personalities, Keith being boisterous and silly and Bari being stoic and serious. This goes as far as the appearances of their spells: Bari's manifest as spirals while Keith's manifest as straight arrows. Most notably, while Bari matures past his BloodKnight tendencies, Keith loses himself to his desire for more power.
* IHaveToGoIronMyDog: At the end of his first match with the heroes, they are incapable of fighting back but Keith himself is out of spells and badly injured. So he bails out of the fight without either admitting defeat or pressing his luck by claiming he's going to go get a snack.
* {{Jerkass}}: Keith outshines even the most overtly evil demons, simply because he's a ''massive'' asshole.

* AdaptedOut: Doesn't appear in the anime as the story there ends with Zeno as the final opponent.
* TheAloner: Gorm was alone in the demon world, with no friends or family. His partnership with Clear is based on a lack of attachment with any of the other demons, with Clear being willing to allow him to live so long as Gorm is the only one left. Once [[spoiler:Kanchome befriends him, he decides to oppose Clear.]]
* BecauseYouWereNiceToMe: [[spoiler:The reason behind his HeelFaceTurn.]]
* BigCreepyCrawlies: Gorm's appearance is similar to a beetle.
* DarkAndTroubledPast:
** Mir is implied to have been a former moll for the Russian mob. It explains her behavior regarding her sadism and unpleasantness along with her fear in defying Clear Note, as seen with the scars on her backs.
** Gorm's willingness to allow Clear to kill everyone else is alluded to be because he lived alone at the bottom of a deep hole and so had no friends or family.
* DiabolusExMachina: Gorm's ability to teleport makes him this trope on two legs. He's able to catch Earth at his weakest and elminate him from the tournament. And Clear only survives his battle with Ashuron due to Gorm being able to teleport him away before Zatch and Brago can take advantage of the opening.
* LastOfHisKind: This is his plan, to win the battle alongside Clear and [[spoiler:let Clear kill all the other Mamodo with the King's Privilege and then kill himself, leaving Gorm the only Mamodo left.]]
* PowerOfTheVoid: His spell theme. Works slightly different from Clear's and looks drastically different. Seems to work more like a spatial anomaly rather than annhilation.
* ThinkingUpPortals: He has the ability to create wormholes that can be used to warp anywhere in the world or even to alternate planes of reality. And critically, it's simply an ability he naturally has, he doesn't need his spellbook partner to cast anything.
* TheUnintelligible: Gorm, albeit Mir (and arguably Kanchome) can understand what he is saying.
* VillainTeleportation: His shtick is creating wormholes to travel through. This is extremely dangerous, as it lets him and Clear attack from out of nowhere and instantly retreat to safety whenever they want. And uniquely, he doesn't even need his spellbook to do it, it's simply something he can do at will.
* YouHaveOutlivedYourUsefulness: [[spoiler: When he rebels, Clear slices him in half, fully intending to kill him. Zatch is able to send him back before he dies]].

A demon child resembling a centaur crossed with a gorgon. He boasts the most victories in the previous battle, sealing over 40 mamodos into lithographs, which set the stage for Zofis's plans in the next battle.

* OneManArmy: He personally defeated at least 40 Mamodo, nearly half the contestants in his battle to be king.

A female 1,007-year-old humanoid Ancient Mamodo and one of Zatch's friends. Alone among Goren of the Stone's victims, Laila was staunchly opposed to Zofis's ambitions and aided Zatch and his friends from the moment she met them. Her spells focus around the crescent moon on the end of the wand she carries, which can fire energy beams, grow gigantic, and even multiply.
----

* LittleMissBadass: A tiny little girl, and still one of the most powerful demons we see.
* LittleMissSnarker: Once the stone of moonlight is destroyed, Laila starts smack-talking Demolt like there's no tomorrow.
* {{Lunacy}}: Laila's spell theme is geared towards crescent moons.
* NotSoAboveItAll: She's shown to be a serious character quite unlike the protagonists. After she properly joins them, the next chapter features her comically forgetting the castle's traps and triggering the kind of hijinks common to the series.
* PintSizedPowerhouse: She's small, but still able to throw ''Demolt'' around.
* TheStoic: Laila's facial expression rarely changes, except to occasionally give a rather charming smile.

* CombatPragmatist: Jumps the heroes expressly because he knows they are exhausted.

A male 1,006-year-old Ancient Mamodo a few dozen feet tall, and one of the Four Supreme Demons. He resembles an Egyptian mummy and is almost always sitting in a large stone throne. Not particularly evil, but rather childish; he can be easily appeased with entertainment, but grows angry if tricked or bored. The E. and O. in his name stand for Japanese words that translate to "chair" and "punishment".
----
* AxCrazy: He's the worst kind of nutcase, the kind with two chair-mounted machine guns and magical powers.
* BewareTheSillyOnes: He [[spoiler: nearly kills Dr. Riddles and is so strong that Kido is forced to sacrifice himself in order to beat him!]]
* NeverMyFault: He tries to sing along to Folgore's song but bites his tongue and proceeds to blame him for it, with Folgore protesting it's obviously not his fault.
* ObfuscatingDisability: It's not clear whether he was deliberately pretending to be stuck in his chair, but it still comes as a shock to Professor Riddle that Belgim is capable of standing up and smacking him with the chair.
* PsychopathicManchild: Subverted. He has the appearance of a mummy and towers over even the adult humans and has a very childish personality, but per the rules of the contest he really is a child.
* UnskilledButStrong: He could have easily blown away his enemies had he fought them properly, fortunately his antics allowed them a chance at victory.

* CheshireCatGrin: She sports a disturbing grin from ear to ear.
* EeriePaleSkinnedBrunette: She's dark-haired, pale-skinned, and looks very creepy, which is made worse by Belgim's ghost magic.
* LaughingMad: She's an insane middle-aged woman; the only dialogue she had aside from her spells was mad laughter, though she has enough clarity of mind to cast the spells as needed.
* LimpAndLivid: She's always seen limp and hunched over as she holds her spell book on her hands, all whily sporting a loony grin.

A male 1,008-year-old humanoid Ancient Mamodo child clad in armor, one of the Four Supreme Mamodo, and one of Zatch's friends. Kindhearted in the past, Pamoon fueled his spells with the anger and fear born of 1,000 years of stone when Gash clashed with him. The young king got through to him, however, and established a friendship. Pamoon's spells revolve around the numerous floating five-pointed stars that he controls.
----

* BrickJoke: Zatch and Kiyo find out that Pamoon was the stone tablet that Kiyo bought when Pamoon asks him if he was the human who did weird stuff to him.
* FatalFlaw: He considers it to be his compassion, as back during his war he could have beaten Goren if he hadn't been distracted by an obviously faked hostage.

%%* TheBerserker: Described as one.
* BloodKnight: He laughs after being hit in the face by Ponygon and Zatch.

* CatchPhrase: Refers to a lot of things as "depressing."
* DangerousForbiddenTechnique: His final spell. [[spoiler: Not for him, for his master since it makes Demolt intelligent enough to stop taking orders.]]
* DiscardAndDraw: His final spell greatly boosts his power but he doesn't use any other spells during its duration. Whether this is because he's incapable of doing so or because [[spoiler: him eating his master prevented any spell calling]] is unclear.
* DumbMuscle: He's supposed to be this. The fact that he's actually fighting strategically is what clues Laila in to the fact that his partner isn't controlled.
* NamesToRunAwayFromReallyFast: In the Ancient battle, he was known as 'The Crazed Warrior, Berserker', a juggernaut that used brute force rather than tact to win his fights; Zofis used him as the guardian of the Stone of Moonlight.

!!!'''Spell Specialization:''' [[HavingABlast Explosions]]
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/zofis.png]]
A male 14-year-old Mamodo with an androgynous and doll-like appearance, and the first major villain that Zatch faced. He possesses the natural ability to manipulate others' hearts, and began the battle by turning his partner Koko from selfless and kind to as malicious and ruthless as he. He revived the Ancient Mamodos and brought them under his control in an attempt to become king. Though an imperial sort who would prefer leaving the fighting to others, his ability to fly, genius intellect, and Explosion-based spells make him no pushover if he must dirty his own hands.
----
* ArcVillain: Zofis is the main villain of the Ancient Mamodo arc, which concludes with his defeat.
* ArchEnemy: To Sherry and Brago. Sherry absolutely despises Zofis for manipulating Koko and refuses to allow anyone else to take him out. And, despite his attempt to kill Sherry when they first met, Zofis actively avoids a confrontation with them, because Brago absolutely terrifies him.
* BadBoss: All of his minions, and even Koko, are just tools for him to become king.
* BigEater: All Mamodo have big appetite, but in Zofis' case, he prefers huge feasts fit for a king, which mirrors his personality and ambitions. Also, unlike other Mamodo such as Zatch or Brago, Zofis doesn't scarf down his meals [[JabbaTableManners like an animal]]. Quite the opposite, as shown in ep.69.
* CombatPragmatist: At one point he announces his arrival by blasting another demon's book before they even knew he was there.
* DidntThinkThisThrough: He points out to Sherry that she ''can't'' kill him, because then he couldn't erase Koko's memories, meaning she has no choice but to send him back to the Mamodo world. Brago points out that once he gets back, there's nothing stopping Brago from coming after him.
* DirtyCoward: Hides behind his army of Thousand-Year-Old mamodo, who he keeps in line with the empty threat of returning to stone. When Brago finally confronts him, he spends most of the battle running away, and when he's finally taken down, he's a teary mess.
* EffeminateVoice: His makeup and dress already make him effeminate enough, but the fact that he's voiced by women in all languages make it really impossible to tell he's male without looking into his pronouns.
* EvilSorcerer: Unlike most Mamodo, Zofis has powers that go far beyond his book spells. He can manipulate minds and hearts through hypnosis, extract memories with remarkable precision, and fly unaided.
* {{Expy}}: His look, personality, and even his attacks are very reminiscent of Freeza from ''Franchise/DragonBall'', and in the dub's case he even sounds like Freeza's old dub voice [[note]] by vitue of Susan Silo doing her [[WesternAnimation/XiaolinShowdown Wuya]] voice [[/note]].
* FailedASpotCheck: Subverted. Zofis, despite his strong perceptive abilities, somehow completely missed that Brago had intercepted the spell Zofis had shot at Sherry when they first met. Brago flat-out refuses to believe this and comes to the conclusion the Zofis had indeed noticed him and fled out of fear. Zofis' TearsOfFear are all the confirmation he needs.
* FangsAreEvil: He has a mouth full of fangs that he shows off when he's making the point of how evil he is.
* FauxAffablyEvil: He usually speaks in a calm, polite tone, even when trying to kill the heroes.
* FemmeFatalons: He's an utterly evil SissyVillain with long, red nails.
* HavingABlast: His powers are centered around [[StuffBlowingUp explosions]].
* HellishPupils: His eyes turn yellow/red with slitted pupils when he's being particularly evil.
* HypnotizeTheCaptive: Because Koko refused to be Zofis' partner, he used his power to corrupt her mind and heart so she would enjoy doing evil with him. Sherry is determined to defeat Zofis and free Koko from his control.
* InferioritySuperiorityComplex: There are hints that he felt inferior back in the mamodo world, but as the BigBad, he styles himself like the king he intends to be.
* KnightOfCerebus: The series takes a notably darker turn during his arc, and he's one of the first villains to have absolutely nothing funny about him.
* ManipulativeBastard: Literally; he has the power to manipulate the hearts and mind of humans and Mamodos alike. Even when he has to use mundane methods like against Sherry, he displays a thorough understanding of how to mentally break people.
* SissyVillain: His face, lipstick, colored fingernails, dress, and even his voice (to an extent) are all extremely effeminate, which somehow makes him even creepier.
* SmugSnake: He actually is incredibly powerful and can do things such as fly, teleport, and mentally dominate others without the use of his book. But when faced with someone he knows is his equal or superior, he isn't as smug.
* TyrantTakesTheHelm: His ultimate goal is to become king of the Mamodo world and rule with an iron fist. [[spoiler:He fails.]]
* VillainousBreakdown: He starts losing his composure when Brago and Sherry enter the conflict. Them singlehandedly defeating his army, Brago's spell actually hitting him, and Sherry becoming immune to his manipulations all push him farther into breaking down. By the time Brago threatens to hunt him down in the demon world, he's reduced to a sobbing wreck.

An 18-year-old French woman who grew up in poverty. Kind and outgoing, she intended to seize her future with her own hands by attending a university. Shortly after she was accepted, Zofis came into her life and, after she refused to help him, brainwashed her into a cold and malicious individual.
----
* AffablyEvil: She rarely loses her cute, smiling demeanor even when she's being evil.
* BloodbathVillainOrigin: After Zofis corrupted her, Koko's first act of evil was to burn her entire hometown and everyone in it to the ground.
* BrainwashedAndCrazy: Zofis used his mind controlling powers to brainwash Koko and transform her into a sadistic person who enjoys doing evil with him.
* ChildhoodFriends: She has been Sherry's OnlyFriend since childhood.
* CuddleBug: A villainous example: Koko sure likes to hug Zofis from behind. But the fact that she's brainwashed the whole time makes it all look very creepy and squicky.
* DamselInDistress: She was kidnapped and brainwashed by Zofis. Sherry's main goal for joining the Mamodo Battle is to rescue Koko from Zofis' control.
* DarkAndTroubledPast: Because they were poor, her family was forced to steal in order to gain the little food and comfort they had, and Koko herself was labeled as a thief because of it, even though she was innocent. Realizing that she would never be worthy in their eyes, Koko chose not to give in to despair and focus all of her energy into her work and studying for school. Unfortunately, Zofis forced her to become his partner and corrupted her mind to make her as sadistic as he is.
* InterclassFriendship: With Sherry. Koko is a poor girl and Sherry is a rich girl, but they have been best friends ever since they can remember.
* LaserGuidedAmnesia: Zofis removes all memories of her actions while evil. He refuses to do so until Brago tells him that if he doesn't, he will personally make Zofis's life in the demon world a living hell.
* LivingEmotionalCrutch: To Sherry. Koko was Sherry's OnlyFriend and sole emotional support for most of her life. When her mother's cruel abuse pushed her to the point of suicide, Koko was the one who saved Sherry and motivated her to live on.
* MindControlEyes: Under Zofis' influence, her eyes are blank and inexpressive, a sign that she really is brainwashed and not simply acting on her repressed desires like Zofis claims.
* MoralityPet: Sherry's friendship with Koko and devotion to freeing her from Zofis are the first indications of her softer side before she starts [[DefrostingIceQueen defrosting]].
* MoreThanMindControl: Zofis attempts to convince Sherry it's this. [[spoiler: It ''almost'' works. Zofis also attempts to invoke this: unlike other people whose minds Zofis simply controlled, Zofis created [[SplitPersonality an entirely different personality]] out of the dark feelings in Koko's heart so that she would be his bookkeeper. Zofis restores her heart to normal after he gets beaten.]]
* PutOnABus: Despite her being Sherry's initial reason for fighting, she totally disappears after Zofis is sent back. Justified, in that she goes off to college and Sherry wouldn't want to remind her of the battle anyway.
* RebuiltPedestal: [[spoiler:Koko, under Zofis' control, tries to break Sherry's spirit by revealing that she actually hates Sherry and is a truly evil person all on her own. In the end, this really is all a trick of Zofis's, and Koko really is the good friend Sherry remembered her being.]]
* SomethingOnlyTheyWouldSay: [[spoiler:Her earrings are styled after some rings she made for Sherry that were supposed to serve as talismans to ward off evil. When Sherry realizes this, that's her proof that the real Koko under Zofis' brainwashing is calling for help.]]

!!!'''Spell Specialization:''' [[ShockAndAwe Lightning]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/0zeon_29.png]]
A male 6-year-old humanoid Mamodo and a warped doppelganger of Gash's, even having lightning spells of his own, he was responsible for stealing Zatch's memories. He is later revealed to be one of the four prodigies with the moniker 'Thunder Emperor'.
----
* AdaptationalVillainy: In the manga, Zeon does start out rather dickish but as the battle goes on we start to see he does have a noble side and that his actions were purely driven by jealously [[spoiler: which he eventually overcomes once he sees Zatch's past]]. In the anime, no such development exists, he's evil through and through and has nothing but contempt for Zatch to the bitter end, even when he's beaten. This was because the author had broken his hand as he was in the midst of the story arc and the anime rapidly caught up before he could do the battle between Zatch and Zeno. So the animation staff just had to go with anything and just ran with what they had.
* AllEncompassingMantle: Zeno's clothes are theoretically exactly the same as Zatch's (albeit a different color), but his always seems to be billowing ominously while Zatch's generally just hangs down loosely like a dress.
* ArchEnemy: To Zatch. He's responsible for Zatch's amnesia and his burning hatred of Zatch is his motivation for most of the tournament.
* BigBad: For the last half of the Faudo arc, and for most of the series seeing as he's the one who removed Zatch's memories.
* BloodKnight: Zeno is very ruthless and it was something he inherited from his father. [[spoiler: This reason is exactly why King Bell gave Bao to Zatch. Bao consumed so much darkness, the spell became dangerous and Zeno, possessing his father's wrath, would've been consumed by it. Contrast this to Zatch, who not only manage to resist it, but ''purify'' Bao.]]
* CainAndAbel: The Cain to Zatch's Abel, though they get better.
* CharlesAtlasSuperpower: His spell selection is similar to Gash's, meaning his feats of extreme strength and speed come from pure physical training.
* TheDreaded: He's feared as "Thunder Emperor Zeno" due to the TrainingFromHell that puts him at a far higher level than most mamodo children [[spoiler: and being the son of the current king.]] Riou, who is no slouch himself, is trembling when they come face-to-face.
* ElementalWeapon: Unique to Zeno is the spell Sorudo Zakeruga, a giant blade made of lightning.
* EvenEvilHasLovedOnes: Even at his worst, Zeno genuinely cares about Dufort. The feeling is mutual, as Zeno is probably the only living thing that Dufort cares about at all.
%%* EvilTwin: He's an evil, white-haired version of Zatch. [[spoiler:Turns out he's Zatch's actual twin brother.]]
* FlashStep: Spams this, often to get behind opponents.
* FreudianExcuse: His grudge against Zatch? [[spoiler:He believed that, since Zatch got the incredible power of Bao, and he himself had to go through TrainingFromHell, that his parents favored Zatch. His HeelRealization hits when he realizes Zatch's bad past yet never wavered from his kind self while also learning Zatch was given Bao to protect Zeno from it.]]
* HardWorkHardlyWorks: Part of what drives him. [[spoiler: He feels driven to surpass Zatch's Bao Zakeruga with his own power, born from his TrainingFromHell. If he can do so, he'll prove to himself that the suffering of said training was actually worth something. He actually is stronger than Zatch during their fight, but he loses because Zatch matches his and Dufort's suffering and the power coming from it with the care from his friends, empowering Bao.]]
* TheHeavy: His actions kickstart the plot, and he's the driving force behind the second major arc of the series.
%%* HeelFaceTurn: [[spoiler: His last act in the human world.]]
* IgnoredEpiphany: He sees [[spoiler: fragments of Zatch's memories, revealing bits of Zatch's past along with the horrific might of Bao.]] He seemingly shrugs it off [[spoiler: though he eventually realizes he was in the wrong. Furthermore, he confessed that if he did win, he would've destroyed Zatch's book to prevent Bao from consuming him.]]
* KickTheDog: Beating Rops was all part of the competition, but he rubs it in by having Dufort Zeker the already burning book, destroying it instantly so Rops doesn't have the chance to give his bookkeeper a farewell.
* MyGodWhatHaveIDone: [[spoiler:Starts undergoing one when he catches a glimpse of Zatch's memories and seeing the corrupted form of Bao. Finally hits it when defeated and sees Zatch's unpleasant past. Sums it up as such: "Forgive me, Zatch. Your brother has been a fool."]]
* PetTheDog: Seeing [[spoiler: Rodeaux]] being willing to risk his life to attack him, Zeon tanks the hit rather than dodge it.
* ThePowerOfHate: His suffering along with the hate from Dufort resulted in his ultimate spell. [[spoiler: He and Dufort were released from it when Bao ate the spell.]]
* ShockAndAwe: Just like Zatch, although he's far more competent with it.
* SlasherSmile: He's very prone to making crazy grins.
* SmugSuper: Fond of using only the bare minimum of force to counter his enemies' spells. This still comes off as him showing off though, since he's beating them with spells that ought to be much weaker than theirs.
* TykeBomb: Trained from when he was ''three'' to be a candidate for king.
* WhenHeSmiles: [[spoiler: During the last clash between his ultimate spell and Bao Zakeruga, he witnesses Dufort shedding tears from Zatch taking in his hatred and suffering... and cracks the first genuine, warm smile in the series from his debut up to that point.]]
* WhiteHairBlackHeart: His white hair is infamous among the other children, along with his ruthlessness and malevolence.
* YouCannotGraspTheTrueForm: Of Baou Zakeruga. Not until he sees [[spoiler: Zatch and Kiyo nearly devoured by its power]], he doesn't.

!!!'''Voiced by:''' Creator/HikaruMidorikawa (JP), Creator/DaveWittenberg (EN)
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/0dufort.png]]
Zeno's partner, a mysterious, quiet young man of unknown ethnicity. His stoic demeanor hides incredible intellect and intense hatred.
----
* AdmiringTheAbomination: He admits that Faudo's power fascinates him, and that he doesn't really care about the collateral damage as long as he gets to see it in action.
* AskAStupidQuestion: Given his Answer Talker power, asking him how he knows something causes him to respond with derision.
* AwesomenessByAnalysis: His Answer Talker ability; anything he can observe, he can answer any question about as fast as blinking.
* BlueAndOrangeMorality: He considers the lives of human beings to have no more importance than the lives of flies. Since no one cares if a fly dies, he figures it doesn't matter if people die. He admits that most people would probably disagree with his assessment. He ends up [[spoiler: moving past this, first as a favor to Zeno and later the experience in his travels being shown gratitude moves him.]]
* DeathActivatedSuperpower: Implied. He states that the Answer Talker comes from dying then coming back to life.
* DeathSeeker: He's enough of one that Zeno's parting words to him are a demand that he live on and not just throw his life away because living is too troublesome. Dufort later gives his reason for living being him keeping a promise to friend, indicating this wasn't an unnecessary gesture either.
* FreudianExcuse: [[spoiler: Dufort was raised in a lab environment from childhood, treated cruelly and anyone kind to him was removed. After years of torment and testing, he was given one final battery of tests that opened the path to his release, all while taunted by the scientist who had ruled his life. Turns out that A) His Answer Talker was being used for military application, B) He was being released into the Arctic to die rather than being freed, and, oh, C) His mother sold him for ten thousand dollars.]] Teaming up with Zeno doesn't seem so far-fetched, considering...
* HeelFaceTurn: [[spoiler:After traveling the world for a little while after Zeno's defeat, he chooses to come back to help Zatch and co. defeat Clear. By using his Answer Talker abilities, he is able to coach each one in what they need to do to get stronger during the 10 month period that Clear was recovering from their previous battle.]]
* HumanizingTears: [[spoiler: When Zatch through Bao takes in his hatred and suffering, crying for him, it ends up making him tear up at the first real sign of compassion. After curing a child in an African village and being showered in gratitude, the display of positive emotion and care moves him deeply, causing him to cry again.]]
* MentorArchetype: [[spoiler:During the Clear Note arc, he helps the remaining MainCharacters bring out their greatest potential via his use of the Answer Talker. He also trains Kiyomaro to stabilize his own Answer Talker ability so that he can use it on demand.]]
* MisanthropeSupreme: Implied during his fight with Apollo, and later confirmed when he and Kiyo finally meet. Kiyo attempts to appeal to him to stop Faudo, but Dufort shrugs it off, rather bluntly saying that he sees no value whatsoever in human life.
* NervesOfSteel: He jumps off a pillar at least three stories tall without flinching, confident Zeno will catch him.
* NoSocialSkills: He's very bad at even carrying on a conversation. Justified, seeing as the only human interaction he's had was through a computer screen.
* NotSoDifferentRemark: With Kiyo Takamine, in the Anime when he mind scans the former commenting about his years of jealousy-fueled neglect received both from his peers and his teachers in life, comparing it to his own harsh lab rat days in the asylum he'd been incarcerated in.
* NotSoStoic:
** Was angered so much when Apollo asked how much hatred he was hiding to the point where he attempted to finish him and Rops off with Zeno's ultimate spell, until Zeno convinced him otherwise.
** [[spoiler: Is moved to tears when he sees Zatch taking in his suffering to free him from it]].
** [[spoiler: He ends up in tears again when the family who's child he cures shows him gratitude. The emotional experience moves him deeply and being shown genuine care makes him weep once more.]]
* ThePowerOfHate: His Answer Talker ability was honed through pure hatred. It's implied his immense amount of heart power comes from this hatred as well. [[spoiler:He loses this thanks to Zatch and Bao.]]
* PsychicPowers: In the anime, Dufort had vast psychic powers for which he was poked and prodded within an undisclosed facility for most of his life.
* ShadowArchetype: Dufort is exactly the kind of person that Kiyo would have become had it not been for Zatch. Dufort's nihilism and misanthropy is a darker reflection of Kiyo's BystanderSyndrome and hatred of others before his character development. Dufort's hatred-fueled Answer Talker ability is also a mirror to Kiyo's [[AwesomeByAnalysis genius level intellect]]. And Zeno's influence on him is the polar opposite of Zatch's influence on Kiyo. The anime is a lot more direct about this.
* SkewedPriorities. He cures a child's fatal disease because the boy's family's wailing was keeping him from getting any sleep.
* TheStoic: He's rarely seen with so much as a twitch.
%%* StrawNihilist: Given his past, it's no surprise. [[spoiler: CharacterDevelopment frees him from this.]]
* SuperIntelligence: Dufort possesses a psychic ability known as "Answer Talker", which allows the user to immediately know the answer to any question. This lets him instantly calculate the best winning strategy for any situation.
* VillainousFriendship: He and Zeno are as close, if not closer, than Zatch and Kiyo. Dufort goes so far as to call Zeno his brother in one of the only genuine displays of warmth he ever shows.
* WalkingTheEarth: [[spoiler: After Zeno's gone, he decides to wander and look for a new purpose.]]

[[quoteright:327:https://static.tvtropes.org/pmwiki/pub/images/cha_riou.png]]
A male Mamodo adolescent resembling a cross between a lion and a centaur, and the second major villain that Zatch faced. Ruthless in his determination to become king, Riou sought to use Faudo to overcome all other demons. His magic shapes his energy into beasts.
----
* AintTooProudToBeg: It kills him to say it, but he virtually begs Kiyo to fix his tampering with Faudo's systems. Kiyo is having none of it.
* AnimalMotif: Lions. His spells also have a beast theme.
* ApeShallNeverKillApe: [[spoiler:He (tries to) kill Kiyo but is content with burning Zatch's book.]]
* ArcVillain: Of the Faudo Arc. At least at first.
* ArchEnemy: Comes to view Kiyo as his main enemy out of everyone opposing him. Kiyo in particular draws his ire for successfully outsmarting Leo at every turn and sufficiently tampering with Faudo's system to prevent Leo from using the giant demon the way he intended.
* CastFromHitPoints: [[spoiler: His curse hurts him just as much as it hurts the victims.]]
* ClownCar: His partner Banikis is inside the ''mouth on his chest''.
* DangerousForbiddenTechnique: His final spell turns him into a giant berserk beast, which he avoids using because he can't distinguish friend from foe in the form and is therefore a danger to his bookkeeper. [[spoiler:He's ''still'' no match for Zeno.]]
* DeadpanSnarker: Banikis, in the manga, mostly at Riou's expense.
* EvenEvilHasStandards: [[spoiler: Having been [[HijackedByGanon beaten by Zeno]], Leo gloats to him that his goal to take over Faudo is a futile one, as he's armed a failsafe device that will send Faudo back to the Mamodo World. Zeno simply smirks and says he'll just wreck the device then, visibly horrifying Leo - he'd intended to use Faudo to win the tournament, not destroy the world, which leaving him in the human realm would inevitably do. Not that he's in any position to argue, as Zeno immediately sends him back]].
* EvilIsPetty: He sets Faudo to attack Japan, even knowing he has barely enough time to do so before Faudo is sent back to the demon world, just to spite Kiyo.
* ForTheEvulz: He attacks Kiyo with repeated small spells rather than hitting him with a big one and killing him instantly, because he wanted to make Kiyo suffer.
* HeroKiller: [[spoiler: Kills Kiyo, temporarily.]]
* HijackedByGanon [[spoiler: Mid-way through the Faudo Arc, Zeno takes over and sends Riou back to the mamodo world]]
* UnstoppableRage: Aforementioned final spell.
* WellDoneSonGuy: We find out in flashback that everything he did was due to the pressure of representing his family in the tournament, and he was seriously conflicted about some of the things he did.

!!Clear Note and Vino
[[folder:Clear Note]]
!!!'''Spell Specialization:''' Annihilation
[[quoteright:228:https://static.tvtropes.org/pmwiki/pub/images/clear_note.png]]
Clear Note is a male humanoid Mamodo adolescent, and the final major villain that Zatch faced. Ruthlessly powerful, he aspired to use the power he would claim as king to kill every demon in existence. He boasts the ability of Annihilation, which allows him to completely nullify all spells and creates pockets of NegativeSpaceWedgie where he chooses.
----
* AdaptedOut: He and Vino don't appear in the anime.
* AntiMagic: The ''Supurifo'' spell family has the ability to completely negate a spell's effect within a given area.
* ArcVillain: He's the villain of the last arc.
* BadPowersBadPeople: An OmnicidalManiac with the power of annhiliation. [[spoiler:It's eventually revealed his desire to destroy comes from having those powers. When ''Shin Clear Seunousu's'' core is destroyed, Clear is reborn without any of his villainous traits.]]
* {{BFG}}: The ''Zarefedōra'' spell creates a gigantic artillery cannon which ''doubles as a projectile''.
* BishonenLine: Played straight with first, then averted with his OneWingedAngel form.
* BloodKnight: He likes to fight, expressing satisfaction when Zatch manages to challenge him and lamenting that his rivalry with Ashuron is ending. [[spoiler:That he doesn't feel this way during the second battle against him is the first sign that his personality is almost fully overwritten by Shin Kuria.]]
* BrainwashedAndCrazy: At the final battle, everyone acknowledges that Vino appears to be under Clear's control. Whether he was always like that is unclear, but it's worth noting that he goes back to being a regular baby once Clear is defeated. Brago also notes that Clear himself may be subject to this, his personality slowly being warped and destroyed by his own spell, the Shin Kuria.
* CombatPragmatist: He's not above using his enemies as human shields and though he admits it's a little lame he's fully willing to simply dodge Ashuron's final all or nothing attack.
* CreepyChild: All Mamodo are children, but Clear Note looks the most human of them all. That's not even getting to the effect he has on Vino, which makes him one, too, as he has a dull dead-eyed look.
* DemBones: The ''Bādorerugo'' spell conjures a giant, white, winged doll, which looks like a dragon skeleton.
* DiabolusExNihilo: Clear gets not a single mention prior to the arc where he's front and center, and promptly shows up to wreak havoc, establishing himself as the strongest demon in the series yet and the final antagonist, with the ultimate goal of erasing all demons from existence - himself included. None of the other demons seem to know anything about him, and no mention is made of his past or reason for being outside of that he is "the power to destroy". Little is said about Vino either, the talking human infant that is his bookmaster.
* EvilutionaryBiologist: He claims his existence and intentions to be the natural result of Mamodo evolution.
* GenericDoomsdayVillain: He's an extremist nihilist whose goals are the destruction of the human and Mamodo worlds and then suicide. He's also [[DiabolusExNihilo never so much as mentioned prior to his arc]].
* InvincibleVillain: His first appearance; he hands Brago his first and only [[spoiler:non-friendly]] defeat, destroys the full-power Baou Zakeruga, and nobody but Ashuron is able to lay so much as a finger on him (Brago pitched in at one critical moment, but only because Vino was out of energy). Interestingly enough, the fights with his various powered-up forms are much more even thanks to the heroes also getting much stronger.
* KillingIntent: His murderous intent manifests as a malevolent, demonic aura. It is so potent, he was able to scare both Brago and Sherry.
* LackOfEmpathy: Using Answer Talker, Dufaux in the Gash Cafe identifies Clear as someone who was born without the concept of love, utterly incapable of understanding it now or in the future. Clear only grasps through secondhand knowledge that the reason people don't destroy things is because they love them - Clear himself feels zero qualms about eradicating all demons because he can't comprehend shared positive emotions with anyone else besides himself.
* LightIsNotGood: Pure white, and pure evil.
* NoSell: The ''Supurifo'' spell family, as mentioned above. Unlike other defensive spells, they don't stop attacks as much as they directly cancel their effects or make them disappear.
* MeaningfulName: The name "Clear Note" can refer to his spellbook being a clear note(book), reflecting his complete lack of humanity and empathy, as well as the clarity of his intent, which is free of emotional attachment. "Clear" can also refer to "nuclear" as in nuclear weapons, which he compares himself to. His most powerful spell appropriately has his name in it, being called Shin Kuria(Clear) Seunousu.
* {{Nonanswer}}: After being asked why he's going to kill all the Mamodo, he replies that he wants to kill all the Mamodo. Though he elaborates more, his reason still boil down to him thinking his purpose in life is to kill.
* NonstandardCharacterDesign: Though the Mamodo in general have highly varied designs, Clear sticks out for his highly humanoid appearance - being virtually indistinguishable from a human teenager, and dressing the part too. This only serves to emphasize his nature as an eerie, unsettling force, even amongst demons.
* NoodleIncident: How did Clear get a baby as a bookkeeper is anyone's guess. We don't know what happened to Vino's parents either.
%%* OmnicidalManiac: To its [[DeathSeeker logical extreme.]]
* OneWingedAngel: Ends up with two such forms, each giving him an ungodly amount of power.
* OutsideContextProblem: A supremely powerful demon of unknown origin who shows up near the very end of the series, with the stated goal of not just winning the Mamodo battle, but eradicating the entire Demon World. For whatever reason, not even Zeno or any of the Bells were aware of his existence until he actually made himself known.
* ParentalAbandonment: States in the Gash Cafe that he never knew his parents, though [[MultipleChoicePast whether he killed them or whether they simply left him, he's not sure.]]
* PersonOfMassDestruction: He compares himself to a nuke.
* PhysicalGod: His final form ends up this way.
* PoweredByAForsakenChild: [[spoiler:We never find out anything about Vino, the baby who wields Clear Note's spellbook]].
%%* PowerOfTheVoid: The ''Radisu'' spell family.
* PureIsNotGood: It's implied that the reason he's so powerful is that his bookkeeper is a baby and can thus supply completely "pure" heart energy.
* RecursiveAmmo: ''Bādorerugo'' can shoot its hands which separate into smaller parts. Every tiny part contains the Annihilation effect of the ''Radisu'' spell family.
* {{Reincarnation}}: Baou's ability to erase evil appears to mean this for him. [[spoiler:When Clear got ripped apart by Baou, it stripped him of his old memories and personality, and even his appearance, bringing him back as a ditzy young child named White.]]
* TheRival: He considers Ashuron this. [[spoiler:To the extent that even after being controlled by Shin Kuria, he still recognizes one of Ashuron's spells, to the dragon's surprise.]]
* SensorCharacter: His ability to sense other demons is unsurpassed as his range goes up to 5,000 km.
* ShadowArchetype: He is considered one to Zatch. Both of their strongest spells are revealed to have sentience. The main difference is that Zatch was able to overcome the corruption of Baou and even pacify it. Clear Note fell pray to his own power and is being used as a puppet by his most powerful spell. He is basically the kind of person Zatch could've become if he were consumed by Baou.
* SoLastSeason: Does this to his predecessors as BigBad by virtue of his methods: he ''kills'' his opponents. As nasty as they were, even Zeno and Zofis were simply content to send them back, but not Clear.
* TheSociopath: The ''Gash Cafe'' special implies that Clear is simply incapable of feeling ordinary emotions, and can only derive pleasure from destroying things.
* VillainForgotToLevelGrind: An aversion. Clear is implied to have gotten stronger between his bouts with Ashuron and explicitly takes the time while recovering from Ashuron's attack to further empower himself.
%%* WhiteHairBlackHeart
* WithGreatPowerComesGreatInsanity: [[spoiler:His current looks, goal and power level comes from him being controlled by his own spell, ''Shin Clear Seunousu'']].
* TheWorfEffect: Delivers Brago the only one of these he ever gets. Brago, after training, returns the favor to his first OneWingedAngel form.

[[folder:Vino]]
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/vino_gb.png]]
Clear Note's human partner, a baby with unthinkable amounts of heart power.
----
* BrainyBaby: Vino seems to be pretty smart for baby, considering that babies normally can't read or talk in complete sentences like older kids. It's hard to tell if this is because of Clear's influence or what, though it's implied he's this because of Clear.
* GooGooGodlike: Vino has a large amount of heart power. We can guess this is probably why Clear chose him to be his bookkeeper.

!!!'''Spell Specialization:''' [[AnIcePerson Ice]]
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/reycom.png]]
A male 8-year-old humanoid Mamodo and the first (second in the anime) enemy that Zatch faced in the battle. His cool, quiet, and laid-back to the point of fault demeanor hides a malicious core that thrives on abuse and wickedness to become stronger.
----
* BlueMeansCold: He has blue hair and his outfit consists of a dark blue shirt with white patches that give the blue a cross design on the front and back and a large silver snowflake in the center of the shirt. His spells allow him to shoot ice out of his mouth.
* EvilCounterpart: His relationship with Hosokawa is a negative contrast to Zatch and Kiyo's early relationship with each other. Kiyo tends to think of Zatch as an annoyance, but still tries to look out for him. Hosokawa thinks Reycom's the best thing that ever happened to him, but still treats him like dirt. And while Zatch is working to make Kiyo a better person, Reycom encourages Hosokawa's descent into villainy to make himself more powerful. On a related note, Reycom's book is blue to Zatch's red.
* AnIcePerson: Reycom's basic spell, Gikor, shoots massive icicles out of his mouth. His second spell, Freezudo, freezes things in ice.
* PoorCommunicationKills: Almost literally. Reycom's book is burned because Hosokawa sought out Zatch to steal his book and use him as well, something Reycom knows is impossible but apparently never mentioned.
* SmallRoleBigImpact: He only appears for a few chapters in the manga, around two episodes in the anime, and is never seen again after his book is burned (except for a cameo in one of the last chapters). However, his actions establish a great deal of the Mamodo Battle and how it works. Kiyo and Zatch had no idea there were more kids like Zatch until confronted by Reycom and Hosokawa in the manga, and it's through fighting them that they learn spellbooks only work for one person, and the Mamodo disappears when their book is burned. The fight also marks the first use of the second spell, Rashield, and when Zatch realizes that the magic is coming from him, as before he thought it was Kiyo's tricks and strategies.
* StarterVillain: He only knows two spells, freely admits he and Hosokawa are only using each other, doesn't work with him at all and is unrelated to any future characters or story arcs. Reycom and Hosokawa are the only team to attack Zatch for reasons ''other'' than to burn his book and become king. But they are the first team Zatch and Kiyo defeat on their path to make Zatch king -- even if, at this point, they don't know it yet.

Reycom's human partner. He's a middle-aged man who went mad with power when he discovered Reycom's abilities, using him to do whatever he wanted while treating him as no more than a tool. He never learned, nor did Reycom tell him, of the demon battle and what he was.
----
* AdaptationDeviation: In the manga, Hosokawa learns about Zatch when he and Kiyo foil some bank robbers. In the anime adaptation, he ''is'' the bank robber.
* LockedOutOfTheLoop: Hosokawa has ''no idea'' what Mamodo are, or of the contest to become king. He didn't even know there were other kids like Reycom until he reads about Zatch in the newspaper -- or when he and Kiyo thwart his bank robbery in the anime -- and then tries to take Zatch and his spellbook, not knowing [[OnlyTheChosenMayWield only the chosen partner can use it.]] This despite the fact that he's been working with Reycom for a while now, who ought to know all this. Apparently, [[YouDidntAsk Reycom just never bothered to tell him anything.]]
* PunchAWall: He does this after getting fired from his job.
* UngratefulBastard: Hosokawa was a poor delivery man who hated his job before meeting Reycom, and used the demon to better himself and take revenge on people he didn't like. Despite that, he sees Reycom as nothing but a tool. When Kiyo furiously points out that Hosokawa is wearing a nice suit while Reycom looks like he just crawled out of a dumpster, Hosokawa just laughs.

[[quoteright:174:https://static.tvtropes.org/pmwiki/pub/images/0hyde.png]]
A male 8-year-old humanoid Mamodo child. Not evil, but ambitious to claim the throne of king and with few regards for the consequences of his actions. He appeared in the anime as the first antagonist that Zatch faced, clashing a couple of times but neither winning or losing.
----
* BlowYouAway: Hyde's spells are wind-based. Jikir is a strong gust of wind, and Jikirga is a concentrated wind blast.
* CanonImmigrant: He and Eido started off as anime-only filler characters with barely two appearances, but apparently were memorable enough that the author ended up including Hyde as one of the Mamodo who helps Zatch in the FinalBattle (thereby confirming that he and presumably Eido were part of the battle to become king) and later in a group photo in the Mamodo world school. They even appeared in the official series calendar in 2007 despite being the only non-plot relevant characters to do so.
* FillerVillain: What he started off as, which was probably a big reason why he and Eido were never seen again shortly after their second appearance. Makoto Raiku would later stealthily include Hyde [[CanonImmigrant in the manga]], albeit only in cameos in the last few chapters.
* MinorMajorCharacter: He's the first villain in the anime and forms one of the few teams which Zatch and Kiyo could not defeat, and also gets an interesting bit of CharacterDevelopment with Eido in their second and last episode, all of which appeared to set the two as important {{Foil}}s to the protagonists in the future. However, after a mere cameo in one of Megumi's concerts, they never appear again in the series.
* SuperpowerLottery: He somehow has powerful wind-related skills that are ''not'' spells, such as making himself and Eido fly around or teleport away in a gust of wind.
* WhatHappenedToTheMouse: He and Eido disappear shortly after their second anime-only appearance. He does get cameos in the manga, though.

----
* BullyMagnet: Hyde first finds Eido when he's being picked on by bullies.
* CoolBoard: Eido likes riding his skateboard while using Hyde's wind spells to fly, though Hyde says it just makes him look like a poser.
* DidntThinkThisThrough: Eido kidnaps Zach and Kiyo's friends to force a confrontation with the pair. Unfortunately, he forgot to tell them ''where to go'' in the note he sent. His own captives berate him for how stupid that was.

----
* BrainwashedAndCrazy: Given Gofure starts trembling and whining when Renji arrived and stopped after a spell was cast, it's likely he also had a forced personality change like Kolulu. The ''Gash Cafe'' special contradicts this, suggesting that Gofure has a somewhat sadistic personality even when not transformed.

----
* RightForTheWrongReasons: Haru quickly discovers that he can only use a certain number of Sugino's spells per day. He assumes this is because spells have a hard limit on how many times they can be cast, not realizing that he's simply drawing from a finite pool of his own emotional energy that he can expand with time.

A male 11 year old Mamodo with the ability to control the wind and move at extreme speeds that encountered Zatch and Kiyo and forced them into a battle in an abandoned building along with his human partner Sebe. This decision would ultimately backfire on the duo however, as choosing an abandoned building filled with metal proves to be just what their foes need to end the battle in their favor. Afterwards, Fein's book is burnt while he is still restrained by Zatch and Kiyo's newest spell.
----
* BlowYouAway: Fein can manipulate and control wind as his primary form of attack.
* FragileSpeedster: Fein has a powerful spell that lets him move so fast he at first appears to be teleporting when he uses it. The tradeoff is that because his body is so weak and tiny he ends up getting effortlessly pinned down by heavy metal debris when hit by a single Jikerdor spell, ending the battle in his defeat.

A male 11-year-old Mamodo with a large arsenal of earth-based spells and his simpleminded but kindhearted partner who battled Zatch and Kiyo in front of his old school. Despite having a poor bond overall they manage to put up a good fight thanks to Eshros large amount of combat spells and raw power.
----
* DishingOutDirt: All of Eshros spells are earth based.
* ManipulativeBastard: Eshros uses Shin's dead mother to motivate him to do his bidding, telling him that she'd be disappointed if he didn't do what he said. This comes back to bite him on the ass when Shin gets tired of putting up with his crap.
-->'''Eshros''': [[EvilGloating I brainwashed this moron so good, he probably thinks I'm his mom at this point!]]
* SmugSnake: Eshros boasts that he's an elite Mamodo who can't be beaten. He does have a lot of spells and even some powerful ones, but he's truly nothing special in the overall context of the series.
* TrademarkFavoriteFood: He likes fish and fried chicken.
* UnskilledButStrong: Despite having a pretty weak bond overall, Eshros and Shin nearly manage to beat Zatch and Kiyo due to sheer raw power thanks to Eshros large number of offensive spells.

* GentleGiant: Despite his large physique, Shin is a selfless, kind, gentle, altruistic, and unassertive man.
* MistreatmentInducedBetrayal: Eshros' manipuation of Shin causes the latter to soon realize just what a vile and cruel kid he truly is, promising to burn his own book himself to prevent him from hurting anyone else.

[[caption-width-right:350:Maruss (left) and Rembrant (right)]]
A male 10-year-old Mamodo who was a close friend of Tia's back in the Mamodo world but quickly turned against her during their first encounter in the human world. Knowing that she hadn't yet found her human partner and was completely defenseless he attacked her and tried to elimate her from the battle to become king right then and there. Luckily, Tia survived his betrayal and soon partnered up with her friend Megumi and later Kiyo and and Zatch to finish the fight against him once and for all. After an intense battle with the two newly allied teams he got his book burnt with one final Zaker attack that sent him back to the Mamodo world for good. His partner was a middle aged man in a white suit named Rembrant.
----
* DramaticallyMissingThePoint: He turns on Tia because, as the contest can only have one winner, every other Mamodo is his enemy. Though only one Mamodo can win, cooperation is vital to gaining an edge and every major player in the battle, even the strongest Mamodo, has at least one or two allies. In fact, the structure of the contest pairing every Mamodo with a human partner suggests that the eventual king being able to team up and collaberate with others was part of the point of the battle.
* ExtraOreDinary: His spells allowed him to summon powerful metal weapons like spiked metal balls or even a giant drill.
* FalseFriend: Tia considered him to be one of her closest friends while the two were still in the Mamodo world. It isn't long before he shows his true colors though, with a nearly successful attack that leaves her wounded and with severe trust issues. Shocked and deeply hurt by his betrayal, she takes a while to fully recover from the physical and emotional pain he inflicted on her.
* {{Foil}}: He is one to Gash in relation to Tia. While in the Mamodo world he pretended to be nice and friendly to Tia, but he discarded all of that once he contest began and targeted Tia specifically because he thought she would be an easy target. Meanwhile, despite Gash knowing nothing of Tia from before he lost his memories, he immediatly jumps to protect Tia and defend Megumi's concert. Likewhise, despite his amnesia, Tia observes Gash is still the same person in practice, defending others despite the danger, in contrast to how much Maruss changed when arriving in the human world.
* KickTheDog: He announces that after defeating Tia, he'll attack and ruin Megumi's concert purely to spite Tia.
* TheSocialDarwinist: A firm believer in this, which is why he betrayed Tia. It's also why he's angry when Zatch is able to beat him, since it basically deconstructs his whole philosophy.
* SoreLoser: Maruss is FURIOUS when Zatch is able to surpass him.
* ThisIsADrill: His ace spell Gigano Garanzu summons a massive spinning drill to attack the opponent with.
* TrademarkFavoriteFood: Maruss likes fish, korokke, and tulips.
* UnskilledButStrong: His spells tend to lack subtlety and utility but make up for it with sheer raw power.
* VillainousBreakdown: Becomes increasingly enraged as Zatch (who he used to bully) not only holds his own, but dominates him during the fight.

A male 6 year old Mamodo and his partner who lure Zatch and Kiyo to a giant inductrial freezer by kidnapping Suzy and holding her hostage. It turns out to have been all a clever trap to force Kiyo and Zatch to fight them at a severe disadvantage due to the cold and allow Robnos to make full use of his laser beam and duplication abilities. After temporarily disabling one of the Robnos twins with a Jikerdor spell the two then fuse into their ultimate form for the final stretch of the battle. Seemingly outmatched and outginned against such a powerful opponet a bit of quick thinking from Kiyo saves the day and Robnos is sent packing back to the Mamodo world. As for Suzy... she was never captured by the duo to begin with, just out sick.
----
* CoolHelmet: It's actually a huge factor in his defeat. Kiyo was able to correctly guess that his attacks required him to build up power in his helmet before firing and used a metal pole to turn him into a giant lightning rod.
* EyeBeams: Robnos' most basic spell is a simple laser beam fired from his eye. Unfortunately, the location of the battle allows him to reflect it off of multiple surfaces to hit his target, making for a surprisingly dangerous basic attack.
* FusionDance: There are actually two seperate Robnos at the beginning of the battle that combine their attacks to hit Kiyo and Zatch whenever they try to dodge one of their laser beams. After the second one is captured by Jikerdor, Ruku uses a spell that lets them combine into a single more powerful entity.
* NoSell: Subverted. He pretends this happened with Zatch's Zaker spell, but Kiyo realizes that wouldn't have prevented his clothes from being burnt and figures out that he switched himself with another, unburnt copy.
* ThirdEye: His fused form has three eyes which allows him to fire three laser attacks at once.

After their battle with Zatch and Kiyo starts going south, he and his partner decide to make a quick escape and flee while the castle crumbles to the ground around them. Luck isn't on their side however, as Zeno was waiting to prevent them from making a clean getaway and burns their book with a single spell.

A 7-year-old lizard Mamodo, originally teamed up with Papipurio and Lupa before their lack of teamwork caused them to go their separate ways. Zoboron is a silent female Mamodo that resembles an iguana and with her partner Hige, they fought against the protagonists at the amusment park and actually had them on the ropes for a bit with their combo attacks before a fight between them ends their partnership.

* BornLucky: Manages to [[spoiler: get into the last ten demons]] despite being absurdly weak.

A female 7-year-old humanoid Mamodo and one of Zatch's friends. She has an obsessive one-sided crush on Zatch, and misplaced anger led her to serve Zofis in the battle. Very vain, but not without conscience. Her spells are Water-based.
----
* AdaptationDyeJob: In the illustrations on the covers of the manga, her hair is a pinkish white color, but in the anime, it is turquoise. Also, her crown hair accessories are blue in the manga, while they're yellow in the anime.
* AnimalMotifs: Her twintails are styled to resemble rabbit ears and her dress has a white ball attached to the back of the waist, mimicking a rabbit's tail.
* BitchInSheepsClothing: She's extremely cute and sweet at first glance, but beneath that face, she's ''extremely'' selfish, vain, and ultimately just unpleasant.
* CuteAndPsycho: At first, she comes off as sweet and nice, if vain. Once she learns Zatch doesn't remember her, however, she turns into a rabid lunatic.
* DistaffCounterpart: To Zatch. When she cuts off her hair in the Millennial Demon Arc, she looks almost exactly like him. Many of their spells mirror each other as well, most notably "So Giaku" and "Baou Zakeruga."
* ElementalBarrier: She can create a shield made from water that can also absorb electrical attacks.
* ElementalEyeColors: She's a blue-eyed water user.
* ElementalHairColors: The anime gives her blueish hair to match her water element.
* EntitledToHaveYou: She's absolutely convinced that Zatch owes her reciprocating her feelings because she has been obsessed with him since the first time she saw him. In her mind, Zatch accepting fish from her is undeniable proof that he's her boyfriend. She finds it extremely insulting that Zatch forgot about her, even though he has amnesia and she never made that much of an impression on him regardless of that.
* EvilIsPetty: She joins in with Zofis simply because Zatch doesn't remember her in the Demon World despite the fact he lost his memory, finding it unforgivable that he forgot about her regardless of the reason. Kiyo tried to explain this to her, but due to some [[PoorCommunicationKills bad communication from Zatch]], it just makes Penny think she's being taken advantage of.
* GirlishPigtails: She's a very immature brat with her hair styled in two pigtails pointed upwards.
* GoofyPrintUnderwear: Her panties have an image of Zatch's face.
* HeelFaceTurn: In the Ancient Mamodo Arc. [[ArmorPiercingQuestion After Zatch demands to know if Penny is aware of how awful she's treated the other Ancient Mamodos and their brainwashed human partners, along with all the other terrible things she's done]], Penny tries to redeem herself by helping defeat Demolt and destroy the Moonlight Stone with Byonko and Alvin. It's also the first time Uri actively helps her instead of just following orders, as she's doing something noble for once, even giving Penny orders instead of the other way around, to which she agrees.
* HeroicSacrifice: Catches Demolt's attention so he would attack her instead of Ururu. [[spoiler:Zatch and Ponygon keep her from dying, although her book is still burned.]]
* ImportantHaircut: She cuts her pigtails off to use in distracting Demolt, cementing her HeelFaceTurn. The grand finale shows she keeps the shorter hairstyle.
* ItsAllAboutMe: She only cares about what she wants and throws a fit when things don't go her way. During a flashback of their early adventures together, Penny made Uri sound like an UngratefulBastard when he was trying to warn her about how selfish her actions were, even outright stating that he was starving for food ''and'' work before Penny met him, and is now able to eat three meals a day because of her. It isn't until the battle with Demolt that Uri finally gets through to Penny about how her selfishness won't be enough to either defeat Demolt or destroy the Moonlight Stone, leading Penny to realize that she also needs to follow orders from Uri in order to work together and accomplish their goal.
* KickingAssInAllHerFinery: She always wears a blue PimpedOutDress, even when she goes into battle.
* LittleMissBadass: In their first battle, the small Penny was actually kicking Zatch's butt for a good portion of the fight.
* LoveAtFirstSight: She was smitten with Zatch while watching him wrangle a fish from her private beach.
* MakingASplash: All her spells revolve around the power of Water, which she can use to absorb Gash's Lightning powers and send it right back at him, proving her powers to easily counter his. Of course, after her HeelFaceTurn, she and Gash's powers combine to fight against Demolt in order to help destroy the Moonlight Stone.
* NightmareFace: She puts on a pretty nasty face whenever something or someone sets her off.
* NotGoodWithRejection: Anytime Zatch doesn't recall her or rejects her feelings is all she needs to go off the deep end.
* PetTheDog: Though she was ''totally'' selfish and committed illegal acts in order to do so, her helping provide for Ururu's family ''was'' pretty nice of her.
* PrincessPhase: She dresses like a fairy tale princess and dreams of marrying a prince [[spoiler:which is why she's so obsessed with Zatch.]]
* PuppyLove: She's a 7-year-old kid with a big crush on Zatch, who is only a year younger than her.
* SelfProclaimedLoveInterest: Inside her head, she's Zatch's girlfriend, but in reality, she was just a [[StalkerWithACrush stalker]] and had no real interaction with him besides her giving him a fish as a present. Whether or not he had amnesia, asking him to remember her would have probably been pointless.
* ShapingYourAttacks: Her strongest spell creates a huge dragon of water to attack her foe.
* SpoiledBrat: It's implied that her parents are rich, since she has her own private beach in the Mamodo World, which would help explain why she ended so self-centered and self-entitled.
* StalkerWithACrush: No matter how much she sugarcoats it to make it seem like she was Zatch's girlfriend, it is pretty obvious in flashbacks that she was just an obsessed stalker who deluded herself into thinking Zatch liked her because he accepted a fish from her.
* SweetTooth: She loves sweets in particular.
* ThirdPersonPerson: In the original Japanese, she refers to herself in the third person, calling herself "Patie-sama".
* TinyTyrannicalGirl: Her dynamic with Uri is basically her bossing him around and having him fulfill her every whim because she knows he can't say no to the one who is keep him afloat.
* TookALevelInKindness: She starts as an absolutely selfish, entitled, and petty brat, but becomes nicer after her HeelFaceTurn.
* TrueBlueFemininity: She's a very feminine girl who always wears a blue dress.
%%* {{Tsundere}}: Towards Byonko.
* WaterIsWomanly: A young girl who likes pretty things, has obsessive romantic feelings for Zatch, and wears a blue dress. She uses water spells, one of which forms a huge dragon made of water.
* WomanScorned: She feels scorned by Zatch because he forgot about her, even though that's Zeno's fault, and makes it her main goal to make him pay for hurting her feelings, even joining Zofis' side to get back at him.
* {{Yandere}}: She has an obsessive crush on Zatch and goes ''livid'' when he admits he can't remember her (because of his amnesia), swearing to burn his book for forgetting his "true love".

Their bond only truly connected when he found his courage and Penny found her conscience.
----
* AdaptationDyeJob: His hat is yellow in the manga, but the anime changed its color to brown.
* BeleagueredAssistant: He has to put up with ''a lot'' because he depends on a selfish brat to support himself financially.

A male 6-year-old Mamodo resembling a frog, he was a loyal servant to Zofis. Childish, naïve, and annoyingly persistent, he wants nothing more than friends to play with.
----
* BigDamnHeroes: Double-subverted. He tries to come from out of nowhere to save Patty from Zatch's Baou Zakeruga, but forgot that Alvin wasn't there to actually cast any of his spells and he gets blasted alongside her. Still, there being two targets instead of one diffuses Baou's power enough that they both survive. Played straight after his HeelFaceTurn.
* CrouchingMoronHiddenBadass: Byonko is pretty much a joke. He only ever shows up to get his ass kicked and Alvin doesn't read the spells to help him. But once he does, the first thing Byonko does is knock ''Demolt'' on his ass.
* EndearinglyDorky: Alvin promised to give him a cookie at three o'clock, so Byonko made a fake clock set at that time. It was stupid and cute enough to convince Alvin to participate in the battle to become king.

A male humanoid Mamodo adolescent and one of the Usurpers among the Faudo Cultists. A proud and strong demon who desired nothing more than being the strongest, he has a well-hidden heart of gold beneath the surface. His will is indomitable, and he gives allegiance to nobody but is not above allying with others. His bat-like wings are the medium and focus for his powers.
----
* BetterToDieThanBeKilled: [[spoiler: Lets his book be burned rather than be torn apart by the Faudo cells inside him.]]
* CurbStompBattle: When Kiyo woke up, he stood no chance against Zatch's new powers. After a barrage of attacks from Kiyo, he lies on the floor while they turn their attention to Zeno.
* DoNotGoGentle: [[spoiler:As his own body is destroyed from within, Rodeaux continues his attacks on Zeno not letting his increasing wounds slow him down. This situation also serves as a RousingSpeech for his partner Cheeta who became emotionless from losing an eye.]]
* DoomedMoralVictor: [[spoiler: He can't resist Zeno and even attempting to causes his body to tear itself apart, with Rodeaux clearly defining his victory as him asserting his independence from Zeno's control rather than actually inflicting damage.]]

A male Mamodo child and the only demon among the Faudo cultists that was loyal to Riou. He has several eyes, which grant him magically enhanced sight, and is clad in dark clothing that covers everything below his eyes. Cool, calculating, and vindictive to those who wrong him, yet despite his enhanced sight, he experienced tunnel vision when it came to his goals. His power over shadows makes him a formidable foe.
----
* AlasPoorVillain: As his book burns, he laments that he wasn't friends with Leo and that after all their hard work, the grand vision they once had was stolen from them with ease by Zeno. His last act is to apologize to his partner for being a handful.
* AntiVillain: Despite what he says, he's really only in it to help Leo.
* DeathGlare: Gives one to Fango. An omake panel reveals he was absolutely ''seething'' despite his apparent composure.
* DoomedMoralVictor: He rejects Faudo's power, seeing accepting it as a betrayal to Leo, and his fight with Aleshie is so close he probably would have won with it.
* EnigmaticMinion: His motives remain a mystery, even to himself.
* EyesDoNotBelongThere: He has eyes on all sides of his head and on his palms. They emit the light he needs for his shadows.
* HumanShield: He uses Fango as a shield to survive Aleshie's ultimate attack.
* IJustWantToHaveFriends: Implied. In defeat, he laments his loss to him and Fango lacking teamwork and even asks himself why he felt misery at seeing Leo be defeated.
* LivingShadow: His power includes shadow manipulation and creating things made of shadow.
* SinisterSchnoz: Raushin, especially in the manga, where it's *long* too.
* TeethClenchedTeamwork: He and Fango are all but attacking each other despite being on the same side.
* TragicVillain: After Leo is defeated, all he had left was a pointless grudge against Alishie. Alishie recognized how empty he was and pitied him.
* UnfriendlyFire: Fango clips him with one of his spells, badly burning Zaruchim's arm.
* VillainousBSOD: Aleshie sent him into one when they first met. After looking into his eyes Zaruchim was left frozen and trembling. Avenging that humiliation is a major motivator for him.
* VillainousFriendship: Leo's defeat pretty much kills his drive. He later laments that he wasn't even friends with Leo, but it's unclear if he's in denial or sad that their businesslike relationship wasn't more personal.
* WorthyOpponent: His treatment of Riya and Aleshie, especially Aleshie, is an odd case. The gist of it is that he considers them to be this trope, but can't bring himself to admit it, and therefore wants to crush and humiliate them to prove he's the better fighter.

Keith is a male 17-year-old Mamodo child and one of the Usurpers among the Faudo cultists. A quirky but undeniably powerful demon who saw himself as equal to the four prodigies until Bari defeated him soundly. He saw Bari as a rival from that time on, and unlike him, he never was able to grasp the true meaning of strength. His spells focus around lasers.
----
* {{Cloudcuckoolander}}: Keith is nuts, changing moods, hobbies, and whims on a moment's notice. His huge cigar and big gloves make him look like a Looney Tunes character.
* {{Foil}}: Keith to Bari. They're both powerful combatants with polar opposite personalities, Keith being boisterous and silly and Bari being stoic and serious. This goes as far as the appearances of their spells: Bari's manifest as spirals while Keith's manifest as straight arrows. Most notably, while Bari matures past his BloodKnight tendencies, Keith loses himself to his desire for more power.
* IHaveToGoIronMyDog: At the end of his first match with the heroes, they are incapable of fighting back but Keith himself is out of spells and badly injured. So he bails out of the fight without either admitting defeat or pressing his luck by claiming he's going to go get a snack.
* {{Jerkass}}: Keith outshines even the most overtly evil demons, simply because he's a ''massive'' asshole.
* NotSoDifferentRemark: When they meet again, Bari sees himself before his CharacterDevelopment in Keith and gives him a TheReasonYouSuckSpeech related to his inability to overcome his flaws the way Bari himself has.
* TheRival: Keith to Bari. When they meet again, Bari has outgrown the rivalry and finds the reminder of who he used to be annoying.
* SmokingIsCool: Keith has a preference for cigars.
%%* TheStarscream: Until he takes on Faudo's powers, despite his claims to the contrary.
* TookALevelInBadass: Keith gets three powerups from Faudo in his fight with Bari. They make no difference.
* TookALevelInJerkass: Initially, Keith seems immune to the personality alteration of Faudo's power beyond it killing his drive to usurp Zeno. After his defeat however, he activates a death trap and admits that he probably wouldn't have done so without Faudo's influence.

[[caption-width-right:253: Gorm (right) and Mir (left)]]
A male beetle-like Mamodo child implied to be stunted mentally, and grew up with no friends; due to this, he allied himself with Clear Note in the battle, offering his abilities in exchange for being the only one he would spare. The power of his black hole spells coupled with his almost global demon sense make him nearly unstoppable.
::
His partner is a young woman implied to have been part of an Russian mafia. She is somewhat conceited and rather snotty and sadistic but cares dearly for her partner.
----
* AdaptedOut: Doesn't appear in the anime as the story there ends with Zeno as the final opponent.
* TheAloner: Gorm was alone in the demon world, with no friends or family. His partnership with Clear is based on a lack of attachment with any of the other demons, with Clear being willing to allow him to live so long as Gorm is the only one left. Once [[spoiler:Kanchome befriends him, he decides to oppose Clear.]]
* BecauseYouWereNiceToMe: [[spoiler:The reason behind his HeelFaceTurn.]]
* BigCreepyCrawlies: Gorm's appearance is similar to a beetle.
* DarkAndTroubledPast:
** Mir is implied to have been a former moll for the Russian mob. It explains her behavior regarding her sadism and unpleasantness along with her fear in defying Clear Note, as seen with the scars on her backs.
** Gorm's willingness to allow Clear to kill everyone else is alluded to be because he lived alone at the bottom of a deep hole and so had no friends or family.
* DiabolusExMachina: Gorm's ability to teleport makes him this trope on two legs. He's able to catch Earth at his weakest and elminate him from the tournament. And Clear only survives his battle with Ashuron due to Gorm being able to teleport him away before Zatch and Brago can take advantage of the opening.
* LastOfHisKind: This is his plan, to win the battle alongside Clear and [[spoiler:let Clear kill all the other Mamodo with the King's Privilege and then kill himself, leaving Gorm the only Mamodo left.]]
* PowerOfTheVoid: His spell theme. Works slightly different from Clear's and looks drastically different. Seems to work more like a spatial anomaly rather than annhilation.
* ThinkingUpPortals: He has the ability to create wormholes that can be used to warp anywhere in the world or even to alternate planes of reality. And critically, it's simply an ability he naturally has, he doesn't need his spellbook partner to cast anything.
* TheUnintelligible: Gorm, albeit Mir (and arguably Kanchome) can understand what he is saying.
* VillainTeleportation: His shtick is creating wormholes to travel through. This is extremely dangerous, as it lets him and Clear attack from out of nowhere and instantly retreat to safety whenever they want. And uniquely, he doesn't even need his spellbook to do it, it's simply something he can do at will.
* YouHaveOutlivedYourUsefulness: [[spoiler: When he rebels, Clear slices him in half, fully intending to kill him. Zatch is able to send him back before he dies]].

A male 1,006-year-old Ancient Mamodo a few dozen feet tall, and one of the Four Supreme Demons. He resembles an Egyptian mummy and is almost always sitting in a large stone throne. Not particularly evil, but rather childish; he can be easily appeased with entertainment, but grows angry if tricked or bored. The E. and O. in his name stand for Japanese words that translate to "chair" and "punishment".
----
* AxCrazy: He's the worst kind of nutcase, the kind with two chair-mounted machine guns and magical powers.
* BewareTheSillyOnes: He [[spoiler: nearly kills Dr. Riddles and is so strong that Kido is forced to sacrifice himself in order to beat him!]]

Demolt's human partner.
----
* BrilliantButLazy: One of the reasons Demolt is able to give Zatch and the others so much trouble is because of his intelligent fighting strategies, but he outright calls himself the type of person who prefers taking the easy way in life and avoid hard work.
* BrokenTears: Starts shedding these after the Stone of Moonlight is destroyed lamenting about how the promise of having and using it to do something big with his life was what compelled him to finally work his hardest.
* GettingEatenIsHarmless: [[spoiler:Floating around in Demolt's stomach acid after being swallowed by him just knocked him out.]]
* NotBrainwashed: His mind is not controlled and plans to use the Stone of Moonlight to control the minds of humans after Zofis becomes king.
* OhCrap: When he realizes Demolt isn't going to let himself get bossed around by him anymore.
* SanitySlippage: Once the Stone of Moonlight is destroyed he loses it, and impulsively uses Demolt's DangerousForbiddenTechnique despite Zofis warning him of its immense danger. [[OhCrap He comes to regret it not long after.]]
