With human help from the likes of Maria Hill (Cobie Smulders), G'iah (Emilia Clarke) and maybe even War Machine (Don Cheadle), Nick Fury seems to have his work cut out for him as he looks to take on an entire alien race with powers that his everyday firearm can't compete with.
While everyone is asking "where are the Avengers?" Nick bluntly states "This war is one I have to fight, alone" as it's a personal matter to him. Why does he feel this is all on him? Guess we'll have to wait and find out.
