10. Ratonhnhaké:ton (Connor Kenway)
It would have been hard for any character to follow in the footsteps of Ezio Auditore, but Ubisoft's gamble to go from 'charismatic and charming' to 'broody and boring' really didn't work out.
Ezio had a whole trilogy of games behind him, and had become one of the most famous faces in the gaming world by the time Connor Kenway stepped in to become the latest member of the Brotherhood. Unfortunately, Kenway's dark outlook and monotone delivery really didn't make him someone players wanted to get to know.
Being amongst the worst Assassins in the series is one thing, however being the worst Assassin in your entire family is a new level. Having Haytham and then Edward next to Connor really just goes to show how narrow of a character AC3's protagonist really is.
It wasn't all bad with Connor though. For one thing, his eagle-like costume looked much better than the last couple of outfits worn by Ezio in his final outings, and his unique tomahawk weapon should always rank amongst the coolest to be introduced to the series.
