These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
In Japan, Mandala Gundam is fairly popular - evidently due to its especially bizarre design.
This backfired when G Gundam toys were released stateside: Mandala Gundam action figures were always the ones left hanging on the shelves.
Esoteric Happy Ending: While on the personal level it's happy, on the global scale it may not be as happy as it seems. There's another Gundam Fight coming, though the pilots' resolve to preserve the Earth means that it might not be as ecologically-devastating this time round. The tone of the series and the conversation between Chairman Karato and Dr. Kasshu in the finale seems to strongly imply that they will devise a way to make the system less destructive, especially since Dr. Kasshu himself is now free to have another try at creating something that can restore Earth that won't decide to Kill All Humans if it gets a little dinged up on landing.
One-Scene Wonder: Some feel this way about the previous generation of the Shuffle Alliance.
Unfortunate Implications: Screwed with. Despite how well developed certain characters are, their Gundam names and designs will often fall under this. Most notable is Chico Rodriguez, pilot for Neo Mexico, one shot character, star of one of the more popular episodes (due to the lack of falling into stereotypes and one of the first true tastes of the Gundam Association's Corruption), pilots.... Sombrero-wearing, mustache wielding Tequila Gundam. Hoo boy.
America's no exception, with the Rocky-inspired New York street urchin Chibodee Crocket, who also happens to be Neo America's top boxer. Pilots the Gundam Maxter, a giant-ass football inspired Gundam who's shoulder pads become boxing gloves and is constantly surrounded by his devoted Chibodee Gals... But Chibodee is one, if not THE most popular G Gundam characters in America, and his episode is an uplifting look on America's patriotism and pride in Chibodee as a person and pilot.
Wangst: Domon and Rain's relationship slips into this occasionally, notably towards the end of the series.
Not to mention, Rain fully demonstrated that just because she doesn't like to fight doesn't mean she's not good at it, especially after piloting the Rising Gundam to rescue Allenby from DG Cell takeover.
The alternate interpretation is that while Rain ended up with Domon, Allenby still remains single and available
Woolseyism: Chibodee's nicknames for the other fighters are changed from national adjectives, to simply the names of their countries. This avoids accidental allusions to America's use of "Japanese" as a racial epithet during World War II and earlier.
