History YMMV / ZatchBell

* EarWorm: Chi! chi chi chi, oppai! BOING! BOING! [[labelnote: Explanation]]Parco Forgole’s song about...well, groping women.[[/labelnote]]

* {{HSQ}}: Once Zatch starts shooting building-sized lightning dragons out of his mouth, all bets are off. Of particular note is the fight against Clear, as he utterly brutalizes the protagonists [[spoiler: and is then stabbed ‘’through the chest’’ by Ashuron’s horn.]]

** Eido and Hyde. They could've undergone a HeelFaceTurn had they received more development. They could've even served a [[TheLancer lancer]]/[[TheBigGuy big guy]] role in the main cast. Sadly, they were filler, and were never seen again after their second appearance save for a cameo at Megumi's concert in the following episode.

* UncannyValley: The art style makes most of the cast have very strange and often surreal designs. DependingOnTheArtist, even relatively normal-looking characters like Kiyo or Falgore can look downright unsettling.

* CompleteMonster: [[StuffBlowingUp Zofis]], the first BigBad, was easily the most vile of all the evil demon children. A total {{sadist}} and an egotist, he horribly MindRaped both humans and fellow mamodo, both for practical reasons and [[ForTheEvulz for fun]], and enjoyed nothing more than the suffering of others. He also kept an army of 1000-year-old demons in line by creating the illusion of turning them back into stone tablets, thus being able to control them using their fear. He despised Brago and dreaded his power so much that he attemted to take his life rather than simply burn his spellbook and send him back to the Demon World. Most notably, he warped the heart and mind of Sherry's best friend Koko and made her do anything he wanted her to do, specifically if it hurt Sherry in any way (Koko nearly even jumped to a fiery, burning death because of him). His final threat was to not erase Koko's memory of her time as his partner so that she'd always suffer from the guilt.

* EnsembleDarkhorse: Victoreem, for... well everything. On top of his generally memetic theme, that utterly batshit song, and general ham, he's voiced by none other then Creator/NorioWakamoto. His popularity is lampshaded repeatedly in omakes and the ending of the manga.
** Seriously, why isn't this guy a meme already? [[FountainOfMemes He has the the potential for 5 memes already!]]
** On top of that, the manga's fanart corner for fan-created demon children had to announce that they had gotten an absurd amount of Victoreem spinoff entries based on other letters, such as "Extreem".

* HSQ: Once Zatch starts shooting building-sized lightning dragons out of his mouth, all bets are off. Of particular note is the fight against Clear, as he utterly brutalizes the protagonists [[spoiler: and is then stabbed ‘’through the chest’’ by Ashuron’s horn.]]

** Gash has horns on his head when Kiyomaro is forced to wash him after a battle. Other Mamonos have horns, yet it is never brought up ever again.

* IKnewIt: Gash and [[spoiler: Zeon]] being [[spoiler:twins]].

** The introduction of Gash's trademark spell was done pretty well in the English dub. Since "Don't mess with me" (''fu'''zakeru''' na'') doesn't exactly translate well as a pun, the dub instead has Kiyo mishear Zatch/Gash's name as Zack, and he reacts to Zatch's letter by telling him to stop messing around with him and refers to him as "'''Zack or''' whatever your name is"-- triggering the ''Zakeru'' spell.

** Eido and Hyde. They could've undergone a HeelFaceTurn had they received more development. They could've even served a [[TheLancer lancer]]/[[TheBigGuy big guy]] role in the main cast. Sadly, they were filler, and were never seen again after their second appearance.
** Kolulu had excellent potential for a character arc about learning to control her PowerIncontinence, not to mention the fact that Zatch was [[ToyShip pretty plainly sweet on her]]. Instead she's {{Mercy Kill}}ed by Zatch after two chapters in the manga and one episode in the anime.

%%* TheWoobie:
%%** Sherry.
%%** Gash in his past.
%%** The anime had [[NewTransferStudent Shion Hibiki]] in its first filler arc and later JerkassWoobie Maestro in its second filler arc.

** Though, some believe it grew much sooner during the Kolulu arc.

* TheScrappy: Of the three main villains Clear Note is by far the least liked, owing to his [[DiabolusExNihilo lack of connection to the main characters]], his [[UncannyValley extremely offbeat appearance]], and his rather generic StrawNihilist motives (even [[GenericDoomsdayVillain likening himself to an atomic bomb]] at one point). Many fans felt he more or less existed to be the FinalBoss because... somebody has to.

Since "Don't mess with me" (''fu'''zakeru''' na'') doesn't exactly translate well as a pun, the dub instead has Kiyo mishear Zatch/Gash's name as Zack, and he reacts to Zatch's letter by telling him to stop messing around with him and refers to him as "'''Zack or''' whatever your name is"-- triggering the ''Zakeru'' spell.

* AlternativeCharacterInterpretation: Maruss, was he really a BitchInSheepsClothing or was he BrainwashedAndCrazy like Kolulu.

* TheyWastedAPerfectlyGoodCharacter: Eido and Hyde. They could've undergone a HeelFaceTurn had they received more development. They could've even served a [[TheLancer lancer]]/[[TheBigGuy big guy]] role in the main cast. Sadly, they were filler, and were never seen again after their second appearance.

** Ponygon's nickname was dubbed such because he was a pony & Kiyo wanted him gone.

* {{Wangst}}: Gash/Zatch can go a ''little'' overboard with his crying sometimes....
** Then again, he is still a child.
* TheWoobie: There are many. Like Sherry.
** Gash in his past.
** F* ck it. [[WorldofWoobie The whole frickin' main cast.]]
** The anime had [[NewTransferStudent Shion Hibiki]] in it's first filler arc and later JerkassWoobie Maestro in it's second filler arc.

* VillainSue: Depending on who you ask, Clear Note is either a VillainSue or an intentionally over-the-top ''parody'' of {{Villain Sue}}s. He's a {{Bishonen}} GenericDoomsdayVillain DiabolusExNihilo who makes his completely unforeshadowed entrance by beating Brago (until then the strongest character) half to death, defeats the SupportingLeader despite the fact that said leader's skin is explicitly resistant to his powers, comes back stronger every time you beat him up, is a HeroKiller (including one kill from ''thousands of miles away'' while ''critically wounded''), and ultimately required what seemed suspiciously like an AssPull (it ''was'' foreshadowed... over ''three hundred'' chapters prior) to finally defeat. Whether all of this is annoying or darkly hilarious, again, depends on who you ask.

** F* ck it. [[WorldfWoobie The whole frickin' main cast.]]

** F* ck it. The whole frickin' main cast.

* BaseBreaker: Victoreem. For many, he's the EnsembleDarkhorse. For others, he's just utterly random and pointless.
** Purio is another one; whether his survival to the very end of the competition on nothing more than [[LuckyBastard pure luck]] is hilarious or annoying varies heavily from fan to fan.

* {{Woolseyism}}: Ponygon's nickname was dubbed such because he was a pony & Kiyo wanted him gone.

** The introduction of Gash's trademark spell was done pretty well in the dub. Since "Don't mess with me" (''fu'''zakeru''' na'') doesn't exactly translate well as a pun, the dub instead has Kiyo mishear Zatch/Gash's name as Zack, and he reacts to Zatch's letter by telling him to stop messing around with him and refers to him as"'''Zack or''' whatever your name is"-- triggering the ''Zakeru'' spell.
