Plasma is by far my favorite, but I don’t exactly agree with their goals. That being said I don’t quite agree with the goals of the teams in general. I’d rather not be the puppet organization of Ghetsis. Same goes for Neo Plasma. I’d join N in a heartbeat though if we’re specifically talking about black 2 white 2.
Aqua is pretty cool, but as much as I like Archie he’s probably the biggest idiot in the franchise (what exactly would flooding the world accomplish? There are over 300 Pokémon species in this region alone, I don’t think we need anymore life).
Magmas goals are a bit better, and I’m all for land development, but I can’t get past their outfits. I still have no clue what the heck their supposed to be.
Flare is a bit too... them for my tastes. I’d rather not blow up the world. Plus I don’t have a million dollars lying around for me to join them with. I do like their grunts outfits though.
Galactic is overall just stupid. I Just can’t take them seriously with their ridiculous bowl haircuts. Also they have the exact same plan as flare.
Yell is just lame
skull is honestly quite alright, it’s not my style though.
So as much of a cop out it is, I’ve gotta go with Rocket.
