Nick Fury has declared Miles Morales a super hero; now, it's time for that super-hero rite of passage: the team-up! But the new Spider-Man's first team-up couldn't possibly be with the Prowler, could it? It will be if it's up to Miles' Uncle Aaron, who's not above resorting to threats to get his way. But Miles isn't going to take such manipulation lying down, setting up a titanic battle of wills between uncle and nephew - with the Scorpion caught in the middle! The shocking conclusion will set the stage for the ultimate event in the life of any super hero: that day, unlike any other, when Captain America comes calling. Is Spider-Man really going to join the Ultimates?
