You can still fight him. I believe he's on the Library map in multiplayer. Careful he can kill ya one shot with pretty much any gun. Think of it as fighting him on insane, regardless if you're on casual.
Claire Redfield is the hottest female protagonist in the RE series/franchise.
^ But I'd read not too long ago on the Epic forums a post that a guy made, about how people freak out whenever he drops into a match as the reaper. I'm pretty sure there's no chance for someone to become the reaper if they're not already, but I was fairly sure that there was a very small select group of people who have the reaper as a permanently selectable option on their profiles now.
But if there are bot reapers to kill, then that's good!
