Not sure about looking like Charlie Sheen, but it always seems like Nightwing had some sort of weird smirk on his face, made even more unsettling when he's silently beating the living crap out of all of the mooks the combat challenges throw at him. Also, am I the only one that thinks Nightwing had a bit of an emo fringe going on? Didn't fit with the character very well.
