* ActorAllusion: In epsiode 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?
* CelebrityVoiceActor: In the Japanese version, Yoshino was voiced by Yui Aragaki, a famous teen model-turned-actress-turned-singer
* 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.
* FranchiseKiller: Subverted in 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 [[TheyJustDidntCare 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. 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: 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 Masuru, 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 and an American mafia, respectively.
