Personally though, Nero deserves a whole story of his own. He's a really good character, to me at least. They have yet to do him the justice he deserves. If they can't think of ways to weave him into the new DmC Universe, then they should just make spin off games based around his life and his adventures. I don't view him as an unnecessary character to the addition.
I don't think rebooting the Series again with Nero instead of Dante would of been a good idea. I can see people caring less about changing Nero's appearance than Dante's in my opinion, but regardless I think people would of been ****ed if they took Dante out of the Reboot.
