- Actor Allusion:
- Guy usually dresses in white while attending anything that's governmental. His sempai of the Brave Series franchise, Might Senpuuji, wore white whenever he has to partake in governmental relations. The only difference is that Guy wears his suit with a white shirt and blue tie, while Might wore his with a teal shirt and red tie.
- Another interesting one between the aforementioned two are their combat vests. The Brave Series flagship colors are Red and Yellow, Might wears his vest in red, the common GGG male uniform has a yellow vest designed in a similar cut as Might's vest. Guy wears it after regaining his human body in FINAL.
- Dyeing for Your Art: A voice actor example. For the climax of the Goldion Crusher scene in FINAL, Nobuyuki Hiyama was noted to have repeated yelling the iconic line "Hikari ni Nare" until he deemed it perfect. It is noted that he couldn't even speak for more than a week as a result and this scene alone broke two microphones.
- Keep Circulating the Tapes: As it once was, so it is again: in The New '10s and beyond, finding any listing for the official English release of the series can be an adventure, and the series has never been licensed for streaming. A prospective viewer's best bet is, sadly, piracy, much as it was around the turn of the millennium.
- Limited Special Collector's Ultimate Edition: Booze, Sunrise released 200 bottles of LIMITED EDITION BOOOOOOOOZE!!!
- No Export for You: None of the supplementary materials, including FINAL, were ever translated in any official capacity.
- Show Accuracy/Toy Accuracy: As you can see for yourself, the accuracy tended to vary.
- GaoGaiGar itself is a reasonable facsimile (especially accounting for keeping costs low) and the Ryu brothers are actually quite famous for being good, high-quality toys (so much so that bootlegs of them weren't uncommon in American toy stores for many years after the show went off the air). Goldy is also okay, though the hammer is too small, Mike comes out pretty well (though the Giragirahn VV suffers in detail a bit due to cost concerns) and the whole J-Ark set came out surprisingly well, given how incredibly involved (and enormous) it is.
- However... the Guy action figure has a lot of inaccuracies - the armor isn't right in shape or color, the hair isn't the right shape and isn't long enough, his face is off-model, his eyepiece isn't green and the only time he's see-through like this is in the flashback to his creation. Poor Volfogg, however, gets it even worse. The toy focuses on trying to make Big Volfogg reasonably big and imposing, and normal Volfogg and the Gunbots suffer badly as a result, with Volfogg being twice as wide as he's supposed to be. And even then, Big Volfogg's head is about half the size it ought to be.
- Star-Making Role:
- Pizza/Soldato J for Mitsuaki Madono. Madono initially broke into the industry from his performance throughout Yu Yu Hakusho as a competent bit player. But this was the series where he was truly promoted to roles of major importance.
- Volfogg for Katsuyuki Konishi. Though it's kinda hard to see him playing such a stoic character in retrospect. Especially when you consider the INFAMOUS role he played years later...
- Talking to Himself: The majority of the Japanese cast would take on at least 2 characters, which was already a rare move by Japanese industrial standards in The '90s.
- The performance of Kenichi Ogata splitting his voice for brothers Liger note and Leo note Shishioh, especially when they crash into arguments was so superb, it's totally breathtaking.
- Then you have the four Dragon brother robots: Enryu, Horyu, Furyu, Rairyu; along with their combined forms: Choryujin, Gekiryujin, Genryujin, and Gouryujin, that would be a total of 8 distinct performances to voice actor, Shinichi Yamada's credit.
- According to the now late Voice Director Koichi Chiba, Nobuyuki Hiyama was supposedly been immune from double casting since he was the principal actor, but Hiyama eventually did branch off into voicing one possessed zonder victim, and one GGG China operative.
- Unfinished Dub: The DVD release was about half-ways through when Media Blasters put it on hiatus for a year-and-a-half in favour of leeching off the nostalgia of Voltron, after which the rest of the series was released sub-only. Considered by many to be one of the biggest mistakes they could have ever made.
- Unintentional Period Piece:
- Not in the way you might expect — sure, there are pagers everywhere (in the far-off future of ~2005), a lot of the kids wear 90s kid fashion, GaoGaiGar's shoulders are specifically the then-brand-new 500 series shinkansen, et cetera... but the bit that makes the show stick out somewhat painfully as a 90s product is the tendency of Ushi and Ayame to gush over American military equipment. A number of episodes feature one or the other recognizing an American-made military vehicle and gushing over it (often before it becomes a Zonderized threat); episode 39 even makes a joke of them nerding out together. In 1997, this was a pretty common depiction of military fanboys (which Ayame is on top of being a toku geek), but in the 21st century, especially The New '10s and beyond, it can come across a lot differently (and somewhat weirdly, given that this is a Japanese show) thanks to the events at the start of the century. A show of the 21st century could easily be perceived as making a much different statement than GGG intends with this, and the military otaku-ism marks the show as a product of its time in a way that the production staff almost certainly didn't intend at all.
- Episode 4 also hits this problem in a different way. To a lot of Americans, an episode about an out-of-control monster space shuttle might've been a little questionable even in '97, but it still would've been at least somewhat acceptable; after 2003, though, any show anywhere in the world doing this kind of plot would come across as being in terribly bad taste. In 1997, though, the space shuttle program and general interest in space development was still very hot and would only taper off after the events of the new century, so the shuttle story - and even the entire existence of the Space Development Corporation as GGG's public arm - was a natural writing angle.
- What Could Have Been: A proposed third series called GaoGaiGar: Project Z got pretty far along in the production process (enough that a toy was released of one of the new mecha) but ended up being canceled. The series would have involved Mamoru and Kaidou joint-piloting a new version of GaoGaiGar to defend Earth from a new threat.
- If you want to see what it might have looked like, a lot of the concepts for Project Z were later retooled (Along with the concepts for the never-made Brave Saint Baan Gaan) into the unrelated anime GEAR Fighter Dendoh.
- It's been officially novelized, but of course it's Japanese only. There is an ongoing English translation for it as seen here.
- This last entry of the Brave Series entry is ironically the first to embrace the Super Robot Wars franchise, starting from the 2nd Super Robot Wars Alpha, and its over the top nature makes it a fan favorite amongst SRW crowd and becoming even more of the most famous Brave Series entry. It has so far appeared in 2nd Alpha & 3rd Alpha, W, BX and T, with the last one marking its first appearance together with another Brave Series, Might Gaine.
