Any thougts on how the boss characters will work and how "fun" they'll be to fight against?
If I'm completely honest, Saiki and Dark Ash were probably the most underwhelming aspect for me in XIII. Boss Saiki looked so stupid and that throw move took so long, that the fight wasn't even "fun". Dark Ash was bit of a lazy effort in my opinion, although I enjoy the music in that fight. After Mukai in 2003 and Magaki in XI (my favorite fight in the series), XIII felt such a letdown, especially when those games were so "hype" about their leader.
Anyways, the Russian rich guy. The leak picture of him reminded of Silber, so maybe he is hard hitting slow guy? Time Lord (or whatever that was) could use some goofy stuff, like throwing something from different time.
