History YMMV / TheTeacherOfAllThings

** [[spoiler: Ogremon would supposedly die in a HeroicSacrifice helping the Digidestined]]. [[spoiler: He would also return in a stronger form in a later episode, minus the dying again part]].

** [[spoiler: Andromon would directly attack one of the Digidestined against his will before dying as himself thanks to a new Digivolution's debut caused by the attacked child. In here, it is due to Sora and Biyomon Biomerging into Phoenixmon and Lilymon in the 2020 anime]].

* BetterThanCanon: Many fans of ''Adventure'' think this fic qualifies as such. Reasons include removing the humans' PlotArmor which allows the stakes to feel real, having the humans contribute after the initial Digivolution rather than acting as glorified cheerleaders and even having [[spoiler:the humans and Digimon actually fight as one when Biomerged]], CharacterDevelopment for the Digimon and the aversion of ProtagonistPowerUpPrivileges and OutOfFocus for the secondary cast outside of one or two instances. [[ArsonMurderAndJaywalking Also Leomon doesn't die in this one]].

* AuthorsSavingThrow: Due to debuting at the penultimate battle, there are readers felt that [[spoiler: Phoenixmon and [=HerculesKabuterimon=] X]] were underutilised relative to the others. The final chapter has them be the first respondents to Tai's call for help, giving them a bigger chance to shine.

%% Bring Complete Monster examples to this thread before adding any: https://tvtropes.org/pmwiki/posts.php?discussion=6vic3f9h1cy5qivsenw8llok&page=1. Check the FAQ first to see what would qualify characters for the trope, and if there has been previous discussion on the work.

* GrowingTheBeard: The first two arcs suffered from problems with bad punctuation and grammar while following the StationsOfTheCanon with Tai acting as a SpotlightStealingSquad and his tactics making the other characters irrelevant, but just like in canon the story became infinitely better when [[MagnificentBastard Myotis]][[KnightOfCerebus mon]] appears with the plot going into an original direction, the grammar becoming much better, the rest of the Digidestined beginning to get CharacterDevelopment and become more badass, the ''V-Tamer'' parts of the story starting to affect the plot, and the fight scenes improving.

** [[spoiler:Malo]]Myotismon's debut. The jaws on his shoulders are shown to have ''rotting flesh'' dripping down from them with his power allowing him to effortlessly dispatch his opponents, who are all Perfect level, in ''one hit''. It is also revealed later on that [[spoiler:he gained a HealingFactor by draining the energy of the kidnapped people kept in the Sports Center [[AdultFear which includes Digidestined's parents]], meaning that they can't even damage [=MaloMyotismon=] due to him taking them hostage]].
** The hostage situation with Puppetmon. Matt asks for TK back from Puppetmon, which he obliges while secretly planting his strings on TK. So when he threw TK to Matt, [[spoiler: '''he yanked back the strings that were on TK's head''', fully intending on snapping his neck. If it wasn't for Cherrymon replacing him with one of his arms at the last moment due to MistreatmentInducedBetrayal with his illusion powers, TK would have died for real]]. Matt's reaction to [[spoiler: what is supposedly his ''little brother's corpse'']] and his [[RoaringRampageOfRevenge subsequent]] [[BerserkerTears behaviour]] says it all.

** [[spoiler: Ogremon would die in a HeroicSacrifice helping the Digidestined]].

** While Tai isn't given new flaws, many of the traits V-Tamer presented as strengths are reinterpreted as weaknesses due to the context of ''Adventure''.

* HilariousInHindsight: [[spoiler: [=Machinedramon=] is revealed to be the [=MetalGreymon=] Neo Saiba deleted back in V-Tamer. ''Anime/DigimonAdventure2020'' has [=Machinedramon=] be [=Agumon=]'s Dark Ultimate transformation. This fic called the connection around ''5'' years early]].

** [[spoiler:Malo]]Myotismon's debut. The jaws on his shoulders are shown to have ''rotting flesh'' dripping down from them with his power allowing him to effortlessly dispatch his opponents in ''one hit''.

Matt's reaction to [[spoiler: what is supposedly his ''little brother's corpse'']] and his [[RoaringRampageOfRevenge subsequent]] [[BerserkerTears behaviour]] says it all.

** Apocalymon is made up of all the Digimon who died during the events of both V-Tamer and Adventure. Before the FinalBattle, he torments the Digidestined by having their dead allies' faces appear all over his body screaming to them for help.

* ShockingMoments: Chapter 22 might have exceeded this. The result is that the Adventure's team is just as strong as they were during the season finale of ''Anime/DigimonAdventure''. [[spoiler: Specifically in somewhat chronologically order, Myotismon revives as [=MaloMyotismon=] instead of [=VenomMyotismon=]. Angemon digivolves to [=MagnaAngemon=]. The kids nearly defeat Myotismon, but he starts regenerating. Tai and Matt then [[Anime/DigimonTamers Biomerge]] with their partners and kill him again using [=WarGreymon's=] ability to tell where his HealingFactor is coming from and going all out when it is removed]].

** The V-Tamer cast. Due to them losing their partner Digimon by the time of the fic's start and not being able to access the Digital World, they could only show up during the Myotismon arc and the final chapter as a cameo and/or a supporting role. This was somewhat rectified in the sequel due to Digital World access being no longer as restrictive resulting in more screentime in the human world which allows them to contribute more from there.

* AuthorsSavingThrow: Due to debuting at the penultimate battle, there are readers felt that [[spoiler: Phoenixmon and [=HerculesKabuterimon=] X]] were underutilised relative to the others. The final chapter has them be the first respondents to Tai's call for help, giving them a chance to shine.

[[ArsonMurderAndJaywalking Also Leomon doesn't die in this one]].

* HarsherInHindsight: [[spoiler: Andromon suffered a DeathByAdaptation in here. ''Anime/DigimonAdventure2020'' would have the same fate happen to him. Even the deaths are quite similar, with him being used to directly attack one of the children before dying as himself thanks to a new Digivolution's debut caused by the attacked child. In here, it is due to Sora and Biyomon Biomerging into Phoenixmon while the 2020 anime is due to Lilymon]].
