Trivia: Digimon Frontier
- Creator Backlash: Digimon Savers might have actually taken a pot shot at Frontier with the Bio-Hybrid Trio. Just like the heroes of this season, they turned into Digimon instead of being partnered with them - only they were the bad guys, and worked for Kurata. It's hard not to see that as Self-Deprecation aimed at Frontier.
- Channel Hop: Because of the fact that Disney bought out Fox Kids/Saban a year prior, this one ended up airing on ABC Family and in the last season of Disney's weekday/sunday block on UPN stations, Disney's One Too (a spinoff of One Saturday Morning over on ABC), though by this time it had dropped that name.) It likely didn't get onto ABC because Disney was contractually obligated to make this season, and had no interest in the show otherwise.
- Hey, It's That Voice!: Takuya's seiyuu is known for voicing Naruto and Cure Rouge. What's weird, he and the latter are both fire-themed. Kouji's Japanese seiyuu (Hiroshi Kamiya) also voices Nozomu Itoshiki, the main character of Sayonara, Zetsubou-Sensei. Also,
JunpeiJ.P. in the dub version is voiced by Steve Blum who is well known for voicing the token badass characters, like Mugen in Samurai Champloo. Koji is voiced by Steve Staley, who played previously played Ryo in Tamers. Meanwhile Kouichi is voiced by Crispin Freeman. And here's one that'll blow your mind: Mercurymon, the Legendary Warrior of Steel, is Cosmo and Gordy. Also, Tomoki is Katejina while Kouichi is Shinn Asuka
- J.P.'s Italian voice actor is Naruto.
- Kamui and Fuuma of X1999 are long lost brothers in this one. And Kotori happens to be their only female teammate. Makes sense..
- So Leeron is in love with Yoko?
- The extra four kids with Angemon are voiced by Joshua "Tai" Seth as Teppei, Brad "Kazu" MacDonald as Katsuharu, Tifanie "Yolei" Christun as Chiaki, and Brian "Davis" Donovan as Teruo. Dave Mallow reprises his voice role from Digimon Adventure as (a different) Angemon.
- Whoa, Izzy is the Big Bad, and not for the last time either!
- In English, Takuya is...Matt! Meaning Michael Reisz has voiced both The Lancer and The Hero!
- There's also other homage casting to past incarnations, which ends up giving actors roles that were pretty far off from what they signed on for as the first incarnation of the character, which really shows off their talents when they knock it out of the park anyway. Mary Elizabeth McGlynn played the voice of the Digivice in Tamers, and so continues in Frontier... which means she ends up as Ophanimon, who has a lot more to say than "Digivoluton" (occasionally "Matrix Digivolution.") Paul St. Peter played Diaboromon, and therefore the Diaboromon-virus-infected (at least in America) Kokomon, whose highest form is Cherubimon. Paul continues to play Cherubimon in this version, who is the first Big Bad. A far cry from "Go... back... to the... beginning!!" When he returns as Lopmon, Michelle Ruff - Tamers Lopmon - takes over, though as a former agent of darkness reverted to a friendly Lopmon, the role is kinda the same for her. Also, in the movie, Dave Wittenberg, who voices EmperorGreymon (see The Other Darrin), voices all of Takuya's forms.
- No Export for You: Live in Malaysia or Morocco? Raise your hands.
- The Other Darrin: Due to fear of damaging his voice from all of the shouting, Takuya's English dub actor Michael Reisz refused to voice EmperorGreymon, giving the job to Dave Wittenberg instead...only for there to be not nearly as much shouting for EmperorGreymon's scenes. Wittenberg also replaced Reisz as Takuya for the movie.
- A similar situation became close to happening for the Japanese version, when, exhausted from doing all of the pattern voices, Takuya's voice actress (Junko Takeuchi) asked Kouji's voice actor Hiroshi Kamiya to voice Susanoomon for her. However, Kamiya said that she should do it since Takuya's the main character, and the director overruled the request; as a result, Takeuchi voiced Susanoomon as originally planned.
- What Could Have Been: The first character design sketches released in V-Jump showed some of the characters with different color schemes. Additionally, Kouji was originally going to sport long, black slacks instead of the grey capri sweatpants he eventually dons in the show. One of the fanbooks reports that Kouji was originally going to be a female character, an idea that was presumably discarded because the previous season also had a female lone wolf.
- Crispin Freeman was originally considered for Koji in the English dub, but wound up playing Koichi instead.
