Its based on past games, not populaurity of the the individual. So its properly 50% incorrect since I didn't know how to factor in that. I only did this because I was very, very bored. And my bro is keeping me up and preventing me from sleeping right tired.
Everyone over 5/10 is properly gonna reapearing again at some point. Anyone under, well, basically fans of those characters better hope this is wrong.
