AFAIK, every faction in the original UC timeline are batshit evil.
The Earth Federation? Bunch of power hungry assholes who do anything to keep the people in the Space Colonies marginalized because if the colonies become fully independent, Earth has the potential to get screwed over big time (which is a hell of their own making for how much of an evil asshole this government is).
Zeon and their Remnants? SPACE NAZIS! Well, at least in the original MSG. It's been a long time since I watched Zeta Gundam, but I am still gonna assume that many of the Neo Zeon forces are still Space Nazis.
Anaheim/Vist foundation? Greedy war profiteers who'll sell weapons to anyone for a quick buck.
With all these evil assholes in this timeline, it's honestly hard to know with whom to throw in with. Earth Federation has the luxury of being slightly less evil than Zeon. So I'll say, "Fuck it, I'll create my own faction. With hookers and blackjack!"
When is Hathaway's Flash premiering on Netflix? I am always up for some Gundam! I hope it's better than Gundam NT.
