* 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.
* HeyItsThatVoice: Both the Japanese original and English dub went out of their way to bring back actors from previous seasons. English writer/director Jeff Nimoy specifically asked fans on a message board which actors they would most like to return.
** As far as actors that haven't done major Digimon roles go, [[Creator/QuintonFlynn Marcus]] is [[VideoGame/MetalGearSolid2 Raiden]] and Gaomon is [[Franchise/{{Naruto}} Gai.]]
** One-episode character Neon is [[VideoGame/FinalFantasyIV Cecil]].
** Goddamnit, [[Creator/MonaMarshall Izzy]], this is [[Anime/DigimonFrontier the second time]] you've been the BigBad! Are you developing a bad habit on us?
** In the Japanese version, Craniummon is [[Anime/DigimonFrontier Kouji from the previous season]]. Also in the Japanese version, Masaru is [[Anime/MobileSuitGundamSEED Kira]] [[Creator/SoichiroHoshi Yamato]], now more hot blooded.
** Uh guys, is that the voice of [[Anime/DigimonAdventure Myotismon]] that we are supposed to [[AlasPoorVillain feel sorry for when he gets shot in the back]]?
** Japanese [[Creator/RieKugimiya Ikuto]] is [[Manga/FullmetalAlchemist Alphonse Elric]] and [[LightNovel/ShakuganNoShana Shana]].
** Falcomon's first digivolution's voice is noticeable in that it's Creator/SteveBlum.
*** While Japanese ZatchBell fans are likely to recognize Chie Kujiro as Coral Q.
** Creator/CrispinFreeman, Thomas' English voice actor, previously voiced Koichi in ''Frontier''
** Yoshi's English voice actress played Sora in the first two seasons.
** Naruto regulars Creator/StephanieSheh and Creator/KateHiggins as Megumi and Miki respectively.
** Yushima's English voice actor, Creator/KirkThornton, has appeared in every ''Digimon'' dub in some form, most notably as [[Anime/DigimonAdventure Gabumon]] and [[Anime/DigimonAdventure02 Mummymon]].
* 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, 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 [[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.
