Story I not good at but I think I can make a concept real quick. This team (don't know name to call) is really evil and is doing genetic expirements on pokemon (that mean main Pokemon for that team probably got to be a fakemon) (I know I said no fakemon but mm I think now with this as story than quite a few fakemons)
And to do the genetic expirements to the fullest extent they must capture new cuz new has genetic data of all Pokemon's so you a guy just got his starter here's rumers of people altering Pokemon DNA to make them as strong as possible
I just pull that off top of brain so that's all I got for now
