Ezio, then Connor's dad. I don't really like connor, but to all the people who say he was non-charismatic, I think the switch from ezio(Probably the most badassaric badass in history) to a naive and unorthodox character was refreshing for the series
2.Ezio Auditore da Firenze His charisma and leadership were perfectly shown. Altair was too weak of a hero. Just an assassin mostly without too much background in the game. Connor on the other hand had a good background but he is too cliche for me.
Connor isn't even an assassin, he's an annoying brat with hardly any character development. Yes it could be argued he only had one game, but Ezio was a great character 30 minutes into AC II so that's a kinda stupid counter-argument.
