Hmmmm...sorry, I have a technicality. At one point, I traded some pokes to Yellow from Silver that filled in all the remaining gaps. It is how I know that I've possessed all 151 of the original pokemon in one place. This is the only dex I've ever finished, but I don't think I ever claimed it. I've done none of the others, although I don't know why I didn't finish the 4th gen's dex. Maybe because trading legends is too problematic. I would never get close again, since for the 5th gen, I was too late to ask for the remaining pokes, and shortly thereafter, I lost all interest in trying. The last time I tried was when X and Y was new and I got all of the new pokemon right away. I then realized that there is no real purpose behind any of it, and I did a factory reset, purging all the pokemon I had ever collected since the 3rd gen. I now only get the pokemon I want and nothing more.
