This thread has all of the hero stats at max: New! All Updated Hero Rosters (including costumed heroes, trainer heroes and family bonuses)
Did I miss where in the OP they were looking for that? I only saw the question about stats at 4/80.
I’ve actually been meaning to make a thread for each hero with their stats and info, including at 3-70 though. Just haven’t had a chance. @Lumi did a lot of the prep work for that, including making great graphics, I just need to organize and post everything.
