Team Rocket - I'm gonna assume the anime trio here(because I can), then they get pikachu, ash goes away crying and Giovanni loses it when he finds out that the pikachu is not worth all the resources put in to getting it.(Though apparently time does not progress, ash is still 10.)
Team Magma - Nooooooo I hate the hot weather, i get sunburnt enough already damn saidsts >_<
Team Aqua - Well they flood the earth, I don't see the benefit of it but most likely all my electronics get ruined, so F*** them too.
Team Galactic - I have no idea what these assholes even wanted to do.
Team Plasma - Well people and pokemon get seperated, more than likely ghestis' true nature isn't revealed, and assuming this happens in game the plot of black is no longer a copout. Owning a pokemon is now bootleg.
