Nick Fury Jr is not just black Nick Fury. This is Nick Fury with a legacy in front of him who's still fairly new but more comfortable in this spy game. You couldn't tell this story with 616 Nick, he hasn't been anything resembling green for years real time and even longer in Marvel time. The same thing with Ultimate Nick, he's just like 616 Nick where he's been this spy grandmaster since his inception. The characters aren't interchangeable, the are fufilling completely different roles (again a role that Fury has not occupied in years). If we're looking for an Agent Fury, then Nick Fury Jr is the only one to use. So enough with the whining already.
