The first Marvel NOW! variant cover featured below is for Uncanny Avengers, but as you can see, the second one for Jonathan Hickman's New Avengers features Black Bolt, Black Panther, Iron Man and Mister Fantastic. This is possibly a hint that the series will focus on some of Marvel's smartest and most important heroes rather than the street level characters that Brian Michael Bendis put the spotlight on. Below that is another of Young's baby variants for an upcoming issue of the main Avengers series and an Uncanny X-Men #20 variant which seemingly reveals that Cyclops will be facing off against Captain America and Wolverine in the aftermath of Avengers Vs. X-Men.
