* ActorAllusion: In episode 20 of the Dub [[Creator/QuintonFlynn Marcus]] tells Yoshi that he remembers his first house - in fact, [[Franchise/KingdomHearts he's got it memorized]].
** Fans of ''Anime/SCRYed'' will notice that Masaru is basically Kazuma in a Digimon series, both because of his personality (and tendency to punch things larger than himself) and his [[Creator/SoichiroHoshi voice]]. And the all the punching. Did we mention that?
** Misuzu's dub name, Michelle, was taken from her voice actress Creator/MichelleRuff.
* CelebrityVoiceActor: In the Japanese version, Yoshino was voiced by Yui Aragaki, a famous teen model-turned-actress-turned-singer
* DawsonCasting: Yui Aragaki was 18 years old when she voiced Yoshino, who is also 18 herself.
* FanNickname:
** "[=MasaruDaimon=]" for Masaru. [[DidYouJustPunchOutCthulhu Guess why]].
*** Masaru also has "Digimon's Creator/ChuckNorris". [[MemeticBadass Also guess why.]]
** Bio-Trio: Kouki, Ivan, and Nanami.
** Agumon is "Takatomon", due to having the same English voice actor as Takato.
** "Professor Kurazy" for Kurata was popular back when his MadScientist tendencies were at their most apparent.
* FranchiseKiller: Subverted by the United States dub. While the Disney dub became the subject of mockery among pre-existing ''Digimon'' fans for its unnecessary edits and dialogue changes, the real culprit was entirely because Disney just wanted to fulfill its contract with Toei concerning the ''Digimon'' franchise (the show itself did well in the ratings), since Disney had no interest whatsoever with it (which was why ''Frontier'' was aired on Creator/{{UPN}} as opposed to Creator/{{ABC}}- UPN and Disney's contract still had one more year and they shoved it over there). The license was soon picked up by Creator/SabanBrands shortly following the conclusion of ''Savers''.
* TheOtherDarrin: One or two cases in the English dub of the video game "Digimon World Data Squad" due to being done before the TV series. (There's also a few other differences, such as the use of "Digisoul" like the Japanese version instead of "DNA".)
* PlayingAgainstType:
** At least in regards to the Digimon anime franchise, Creator/MasamiKikuchi had mostly played easy-going or friendly roles ([[Anime/DigimonAdventure Jou]], [[Anime/DigimonTamers Dolphin and Grani]], [[Anime/DigimonFrontier Neemon]]), the only exception being a minor villain in a few episodes of ''Anime/DigimonAdventure02'' (Demon). [[spoiler:Kurata, on the other handů]]
** Compare Kristy's personality to that of [[Anime/DigimonTamers Rika's personality]] or [[WesternAnimation/InvaderZim Gaz's personality]] and you'll see a big difference.
* RelationshipVoiceActor:
** In English dub, [[Creator/MelissaFahn Kristy]] and [[Creator/MaryElizabethMcGlynn Sarah]] were [[Anime/DigimonTamers Rika and Rumiko Nonaka]].
** Also from English dub, [[Creator/QuintonFlynn Marcus]] and [[Creator/KirkThornton Homer]] are [[Franchise/KingdomHearts Axel and Saix]].
** Kouki's Japanese voice actor, KENN, is most often known as Judai Yuki in ''Anime/YuGiOhGX''. In the same series, Agumon's seiyuu voiced ''Manjoume''!
* SequelGap: The series followed the 3 year gap caused by the poor performance of Digimon Frontier. Its own poor performance resulted in another 3 year gap for the franchise.
* WhatCouldHaveBeen:
** During the planning stage, Masaru was going to be named "Kouhei".
** Kouki wound up as a near monster who most-likely only got away because of the fact that he never actually ''managed'' to commit mass-murder anywhere near Kurata's level. However, the original plans for him was to be NotSoDifferent from Masaru, being very similar in many ways but unlucky enough to have been found by Kurata instead of DATS.
** The original plan for the series is worldwide {{Delinquents}} tournament using Digimons, and that Yoshino and Thomas would end up being a local gang leader who wields a nunchuck and an American mafia who beat a New York gang all by himself, respectively. Lalamon's wielding a sausage nunchuck in the movie and Kouki's backstory where he beat a foreign gang by himself are probably remnants of the latter plan.
** Ikuto's age was lowered in order to avoid making his revenge against humans conspicuous, and it made him a KidAppealCharacter in the process. Originally, he was supposed to be on the same age as the other two guys, which would explain [[HoYay a lot of things]] regarding him and Masaru.
** There was going to be an episode about Gaomon that revolves around him running away from Thomas due to his own cowardice and leading a pack of stray dogs in process.
** Chika was not supposed to be Masaru's sister. Instead, she was his neighbor who would go on pestering him about the strange things that occur in the Daimon family, with Agumon being one of those things. This is noticeable if you look at Chika's name, because the kanjis that compose her name [[OddNameOut are not symmetrical]], [[FamilyThemeNaming unlike the other members of Daimon family.]]
