* AccidentalInnuendo: Largely thanks to rampant RougeAnglesOfSatin. In many of the stories, we have corpses being eaten by foul ''breasts.''
** In ''Threat of Satanic Commonism'', the heroes meet with the head "breast"[[note]]Presumably "priest"[[/note]] of Moscow.
** In ''The Evil Gods II'', our heroes go to "Washing Dick," and get some ''boobs'' from witches.
** In ''The Titans Strike Back'', we hear it's a co-story with ''Attack of the [[DontMakeMeTakeMyBeltOff Spank]]''.
* {{Anvilicious}}: Disagree with the author about anything? '''DIE.''' The stories aren't at all subtle about this message.
* AssPull: The author having to tell us in parenthesis that God told Jerry about TheMole midscene in ''The Evil Gods I''.
** The [[{{Retcon}} retconning]] of Michael's death at the end of ''Battle with the Witches''.
** When their weapons and prayers fail to defeat Lola, Draco prays for God (never mind that Lola had the ability to make that impossible) to turn his sword into a holy vacuum cleaner, which sucks her up and kills her.
* AudienceAlienatingPremise: The violent religious fanatics who go around killing people and forcefully converting others are supposed to be the ''heroes''. Needless to say, this series doesn't have a lot of non-ironic fans.
* CanonDefilement: Of both ''Literature/PercyJacksonAndTheOlympians'' and ''Literature/HarryPotter''. Even history gets defiled.
** Add ''WesternAnimation/{{My Little Pony|FriendshipIsMagic}}'' to the list.
* CriticalResearchFailure: Aside from those listed in ArtisticLicenseReligion and ArtisticLicenseHistory, the series has made many, ''many'' errors otherwise.
** Some of the errors are from the author not bothering to read or watch the source materials; for instance, in ''The Evil Gods I'', it's said that Zeus was Percy Jackson's father, rather than Poseidon. In ''The Prayer Ponies'', Rainbow Dash is presented as ''male'', Cutie Marks are always called "the marks on their butts," and Celestia's name is misspelled in at least two separate ways.
** In ''Threat of Satanic Commonism'', the Rika and Books that are featured are male when they're really female. [[FridgeHorror This might have been a good thing considering the author views women as subhuman entities.]]
** ''Evil Gods II'' has some Artistic License with US Government: when a president dies (and then comes back and quickly thrown in jail for rigging the election and being Kenyan), ''the candidate who ran against him in the last election'' (John [=McCain=]) becomes president rather than the vice president getting promoted.
** St. George was apparently a demon. Despite being a ''saint.'' It's somewhat more understandable, though, if you consider that he's the patron saint of England, which the author seems to consider an evil country for, among other reasons, Henry VIII cutting ties with the Roman Catholic Church and for being host to [[Literature/HarryPotter Hogwarts]].
*** This isn't helped by Hogwarts technically being in Scotland.
* DesignatedHero: Our "heroes" are self-righteous, racist, homophobic, misogynistic mass-murderers who made ''Stalin'' look sympathetic in universe. Even moreso, they are never seen doing anything positive let alone anything heroic. We never see them feeding the poor, healing the sick, or even stopping to PetTheDog. They get rid of the "villains," and make everyone convert to Christianity, but the Satanists were actually better people than the Prayer Warriors were, and the conversions [[FridgeHorror are almost all coerced thanks to our heroes policy of killing those who refuse]].
* DesignatedVillain: Most of the villains are this, since their "crimes" are often things many people would consider harmless, or simply not choosing to follow the Prayer Warriors' murderous ideology. One interesting example is how PercyJackson does nothing evil while on the side of the villains, but one of his first acts after converting is to [[MoralEventHorizon stone Tyson to death for refusing to convert]]. It's easier to list the exceptions, such as Jupiter, rather than the straight examples.
* EsotericHappyEnding: Satan is defeated, but the United State is now an oppressive theocracy (and in the later installments, England, Ireland and other countries seem to be following suit), Harry Potter has been killed while Voldemort is still on the loose, and a very unpopular Tsar has been restored to the throne, messing up history. Um...yay?
* EveryoneIsSatanInHell: The original reason why this fic series was written.
* FamilyUnfriendlyAesop: If it ain't a Christian, it's a Satanist, and it has to die.
* ILikedItBetterWhenItSucked: The chapters written by Ebony are less preachy, less poorly spelled, better-written and much less disturbing, and consequentially much less fun to read than the chapters written by Thomas. On the other hand, there are gems such as Socrates being referred to as a Roman god, and in the one chapter Noah proofread, Michael struggling to suppress his feelings of attraction to Ginny.
* InformedWrongness: The narration has to tell us just how wrong everything the Satanists do is, thanks to all the OffstageVillainy. Often, it refuses to even specify what sort of "satanic" or "wrong" things the people the Prayer Warriors kill are doing just before their deaths.
* JerkassWoobie: Grover keeps coming back from the dead and getting killed off in many brutal ways. It's almost enough to forget that he's also one of the Prayer Warriors, especially considering he doesn't accomplish that much for them.
* MoralEventHorizon:
** Jerry crosses it by having his wife executed for adultery, first by being thrown off a tower, then stoned to death, then beheaded. It didn't stick, but it shows how far he is willing to go to punish sinners.
** Michael crosses it by carrying out Jerry's sentence on Mary.
** [[PercyJacksonAndTheOlympians Percy Jackson]] crosses it by stoning his half-brother Tyson to death for not converting. Ironically, this is worse than anything he did as a [[DesignatedVillain villain]]. And if that didn't do it, he later kills Ebony ''because she was raped''.
** Ebony crosses it by killing Harry, then killing Ron for finding his body.
** Rachael crosses it by not only [[DisproportionateRetribution killing Idiosy for hacking]], but, after she has escaped from his mansion, burning it down and killing all his guards and wives, which is completely unnecessary.
** Jason crosses it by putting napalm down Socrates' throat, then after proving that he's not a god, leaving him to have a slow death by burning alive.
** Draco, for all his [[DracoInLeatherPants wearing leather pants, so to speak]], crosses it by leading a mob with the intention of killing the entire British Royal Family, "men [[WouldHitAGirl women]] [[WouldHurtAChild children]] and all". He succeeds in killing the Queen, and plans on hunting the rest down after they escape.
** Arguably, the act that makes Dumbledore stop being a DesignatedVillain, at least for the moment, is having Noah executed by being stoned to death because he prayed to God and Satan. Notice that the Prayer Warriors approve of this.
** John Lennon crosses it by nailing a group of Christians to corpses and sets them on fire.
** InUniverse, several villains are considered to have crossed this by doing things that would come off to some people as completely harmless (Venus kissing another woman), or PetTheDog moments (Stalin deciding to allow freedom of religion).
* NauseaFuel:
** The fact that the Prayer Warriors repeatedly point out that they don't bury the enemy's dead. One has to imagine all those bodies, laying around rotting and getting eaten by scavengers.
** Some of the death scenes.
*** Virtually any time someone is stoned to death, especially if you're familiar with how it works in RealLife, as it's a long and painful death.
*** Chiron is killed and eaten by the residents of Camp Half-Blood.
*** "Idiot" and "Benjamin" are impaled and set on fire, and cut to pieces and fed to a dog, respectively.
*** Ginny is blown to pieces by an explosion.
*** Grover's first death in ''Threat of Satanic Commonism''; both his legs get broken and he gets disemboweled by a spear.
* NightmareFuel: Religious extremists taking over a country by force in modern times can be pretty disturbing, especially considering the extremists' very narrow definition of the "right religion," and what they do to people who don't follow it to the letter.
* RonTheDeathEater: Almost all of the canon characters from their respective universes, both heroes and villains, are warped into Straw Satanists. And yes, this includes Ron Weasley himself.
** DracoInLeatherPants: Ironically, Draco is one of the "secret Christians" in Hogwarts. Additionally, [[spoiler:Luke]] joins the Prayer Warriors in [[PercyJacksonAndTheOlympians The Evil Gods Part 1]].
-->'''I Heart Thomas Brown's Commentary''': I was wondering when [[spoiler:Luke]] would appear… but Tommy-boy doesn't seem to realize [[spoiler:Lukey-boy]] was a bit pro-evil .
* SnarkBait
* StrangledByTheRedString: All of the couples, which include Jerry/Mary, Percy/Clarisse, and Luke/Rachael. Draco/Ebony is the only one given any buildup, and they still get together very quickly by most standards, only for Draco to [[RetCon inexplicably marry Hermione later]].
* SurprisinglyImprovedSequel: The parts of ''The Evil Gods II'' in which Ebony was writing. While it's still preachy and has a touch of sexism in the beginning, it's not an AuthorFilibuster like the previous three installments. The characters act more like human beings instead of mouthpieces, the dialogue is not robotic, and the heroes don't [[CurbStompBattle curb stomp]] the first bad guy they see. In other words, if Thomas stayed out of it, it would have been a regular fanfic.
* TheyJustDidntCare: Even ignoring all the spelling and grammar errors, mythological errors, {{Plot Hole}}s, {{Writer Cop Out}}s, and {{Designated Hero}}es or {{Designated Villain}}s, it's hard to excuse the continuity errors. Grover, Annabeth, Clarisse, Thalia, and Harry all show up quite frequently after getting killed off.
* TheyWastedAPerfectlyGoodCharacter: Voldemort, who not only was more in-character than most of the others (although that isn't saying much), was also set up as an enemy to both Hogwarts and the Prayer Warriors. His involvement as a third faction could have made the story more interesting.
* TheyWastedAPerfectlyGoodPlot: Percy Jackson and friends being attacked by members of a ScaryAmoralReligion who want to kill the Greek pantheon in the name of their patron EldritchAbomination could have made a good CosmicHorrorStory. Sadly, it's an AuthorTract.
** So would a story about Hogwarts being destroyed by a group of heavily-armed Muggles who have found out about the wizarding world and want to BurnTheWitch.
*** Even going with the story that exists, Michael's infiltration into Hogwarts might have been more interesting if he found himself forced to reconsider his beliefs, and possibly [[BecomingTheMask become what he was pretending to be]]. Instead, he simply apologizes to God every time he's forced to do something un-Christian, and purposely fails when he can.
** Or a bunch of [[RedScare McCarthyist]] Americans armed with modern weapons who go back in time to the Russian Revolution and try to prevent the Romanovs from being driven out.
* ThirtySuePileup: ''Every'' Christian in the story.
** GodModeSue: Jerry, who [[HijackingCthulhu actually has God at his beck and call]], and is able to [[CurbStompBattle curb stomp]] most people he meets, with very few exceptions (PercyJackson and apparently "Rika").
** PossessionSue: The converted canon characters, [[WeAreTeamCannonFodder when they're not being cannon fodder]].
** PuritySue: All of our heroes...[[JerkSue but it's not a "good" purity they have]].
** RelationshipSue: Mary has virtually no personality outside of being Jerry's girlfriend.
* UnintentionallySympathetic: The villains come across as lovable losers or regular people. In addition, they also give women and homosexuals rights, and allow their followers to have sexual freedom.
** UnintentionallyUnsympathetic: ...And our "heroes" ruthlessly and remorselessly murder innocent people for daring to not share their narrow, hate-filled views on the world. The only reason they get away with everything is because [[HijackingCthulhu they somehow managed to enslave God]].
* UnfortunateImplications: [[UpToEleven To the point where it's hard to consider this YMMV]].
* ValuesDissonance:
** It sounds like someone mixed the author's Bible with an Al-Qaeda training manual. [[DeliberateValuesDissonance May be deliberate]] if this series really is a TrollFic series.
** This even gets seemingly acknowledged in one case in ''Threat of Satanic Commonism'', in which Grover says that Stalin legalized drugs, but [[InsaneTrollLogic since Grover goes by American law, in which drugs are illegal, he has to kill Benry for dealing drugs]].
