- B-Team Sequel: This is the first Gundam TV series created without any input from franchise creator Yoshiyuki Tomino, who departed the series after experiencing a Creator Breakdown during production of Mobile Suit Victory Gundam.
- Executive Meddling:
- In an interview with a fansite, Mark Gatha (Domon's English VA) said that the cast felt that the first 20 episodes were kind of rough because they hadn't gotten a feel for their characters yet, and really wanted to redub those episodes after finishing production. However, Bandai wouldn't let them.
- The show itself was an attempt at this. Imagawa was hired to direct it as he was rather new to the idea of directing and Sunrise thought that now that Tomino was no longer at the helm, they could control the new guy and use him to just push new toys. They didn't realize that Imagawa doesn't take "no" for an answer when it comes to creative control over his work.
- The name changes in the English dub were mandated by Sunrise, as they didn't want to repeat an incident in which various retailers refused to sell toys of the Gundam Deathscythe Hell due to the religious theming of its name.
- Follow the Leader: Although the underperformance of Victory Gundam was what caused the shift to Alternate Universes, it's very likely the show's plot was at least partially inspired by the popularity of Dragon Ball Z.
- Keep Circulating the Tapes: For years, the only DVD release of the series was in short supply and went for ridiculous prices on the second hand market. Right Stuf finally announced in 2018 that a new home video release in DVD and BluRay formats would be released as part of the series's 25th anniversary. The complete series can now be owned for less than $120 US.
- Official Fan-Submitted Content: Domon and Allenby's opponents in Episode 34, Ashura and Skull Gundam, were the winning designs of a contest presented by the Kodansha manga magazines Comic BomBom and TV Magazine.
- Permanent Placeholder: When brainstorming ways of how the Devil Gundam could be defeated, one of the writers jokingly suggested an incredibly cheesy The Power of Love-infused blast of energy from the heroes. Everybody laughed, and the scene was written as a placeholder until the team came up with something better. Nobody ever did, and the Sekiha Love-Love Tenkyoken was born.
- Referenced by...: Episode 17 of Ultraman Z has Yoko in Windam performing a parody of Shining Gundam's Shining Finger attack. The reference is not a coincidence, since a) Ultraman Z is an Ultra Series that parodied Super Robot genres up to eleven, and b) the Alien Barossa in that episode is voiced by Tomokazu Seki.
- Spoiled by the Cast List: The credits list for the western DVD release lists every major character in the series in the credits for every single episode in each episode whether they're in that episode or not (Something rather obvious with Prime Minister Wong and Allenby Beardsley, who aren't even in the first season). This results in Kyoji Kasshu and Schwartz Bruder being repeatedly listed on the same line, revealing that there's a connection between the two before the latter was even introduced when the nature of that connection was one of the big reveals of the final arc.
- What Could Have Been: As noted on the character page, Dr. Mikamura was originally going to be part of the Big Bad Ensemble with Ulube and the Devil Gundam. However, the director couldn't see a character with Motomu Kiyokawa's voice being one of the main villains, so he instead made Mikamura pull a Heroic Sacrifice.
- The Gundams had different draft designs
, some eventually being reused. The Shining Gundam had at least five different drafts, with one of them becoming Ulube's Gundam in the flashbacks. Maxter is supposed to have a cowboy hat; the idea was re-used for Max Revolver. God Gundam is supposed to have a flight mode, a year before Gundam Wing did. One of the Dragon Gundam's original designs became the Feilong Gundam. The Mirage Gundam was based on a rejected Rose Gundam design, if the kepi was visual cue. The Bolt Gundam is supposed to have a metal-chained flail and a battering ram that was used on a few Bolt Gundam model kits. - The Blu-Ray release of the series came with a proposal for a prequel project starring Allenby. It would have been a school battle series where Allenby proves herself among other candidates for Sweden's Gundam Fighter and had a mentor in the cybernetic student council president. Time will tell if it ever gets made.
- The Gundams had different draft designs
- Word of God: The DVD sets have the "G-Files," which are interviews with series director Yasuhiro Imagawa. They explain some of the thought process behind plots (the episode with Saette being inspired by a Turkish film), Gundam design (two of them were winners from a kids' fan contest and he would sometimes giggle when handing a new design to the animators), and why the series is as it is: "we decided early on to ignore what makes sense in favor of if it looks cool."
- Writer Revolt: The plot was completely changed by the director and several people left production.
