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.
Alternate Character Interpretation: What was Char's real motivation for all of this? It's generally accepted that he started the entire war so he could have his final battle with Amuro, but the Zeta Gundam game for the Playstation suggests that he honestly wanted to destroy humanity. His ending in said game shows him getting very angry when he senses Kamille getting Mind Raped by Scirocco, and then showing him in his CCA-era uniform and looking particularly unhappy. When you recall Char's attitude that it would be up to Kamille's generation to correct the mistakes of his own and create a new era, the ending serves to imply that he thought humanity was doomed to repeat the mistakes of the past and would never evolve past their petty conflicts.
Fanon: Because Char's sub-commander/lover Nanai Miguel shares a surname with Usso Evin's mother, fans assume that Usso is Char's grand/great-grandson. This one was actually Jossed by Tomino himself as a coincidence.
The plan was originally for Usso to indeed be Char's descendant. But further into production, the writers decided against that and didn't want to lose all the work on character designs they'd accomplished.
The writers and Tomino had a conflict. The former believed Usso to be Char's descendant, the latter didn't.
God-Mode Sue: All the comments about "This Nu Gundam isn't just for show!" weren't jokes. The suit is barely damaged in battle and let's not forget it when it pushes Axis away. What's a little scary about it is that the Nu Gundam was incomplete: it was rushed into service due to Amuro needing a powerful mobile suit to compete with the Sazabi. This means that the psycoframe isn't fully integrated and the Fin Funnels are rather sloppily just strapped on the back. The completed version of Nu, known as "Hi-Nu Gundam" appears in the novelizations, and is even more badass.
Char again, when you examine his manipulations of Quess and Gyunei closely. Playing two emotionally-unstable and very powerful teenagers like violins just to further his own plans? One of them being a kid that he pretty much raised as a Tykebomb for at very least seven years? Yeah, that's gonna work well.
Gyunei, with the Hostage Situation that he came up with and which ended in the death of Kayra Su.
Quess' defection and subsequent murder of her father was this, especially for people who didn't like her in the first place.
Hathaway's murder of Chan is one of these for others.
Narm: Because the Greek letter "nu" resembles the English letter "v", when written out, "Hi-Nu" looks like "Hi-v", which is one hell of a weird thing to find plastered on a model kit...
