I have at or over 100 or so. I now have all starters at level 100, and all eevee evolutions at level 100. Plus many other ones that I have to fully train. I have to train all the Mega's I have still, which amounts to about, oh, 25-30 more of them so far! I will update this topic asap once I have all pokemon that I need to level 100 in the future!
