These are all of my storyline teams from my first playthroughs of all the pokemon games I played in chronological order. I didn't complete a story until Pokemon Sun but I still wrote down all the teams I had the first time I played each game up until I either got stuck or didn't finish for whatever reason. (most of the time I was too young to strategize I just liked collecting pokemon lol)
Diamond
Pearl
Platinum
Heart Gold
White
Black 2
Y
Sun
(I have no idea i'll have to get my copy of Sun back from my friend
