This will be a post credit scene to Avengers: Age of Ultron
Avenger's Assemble cut scene is at Avengers Academy where we see notable characters such as Moon Knight, Wonder man , Vision , Perhaps the back side of a pointy eared fellow with gills in the likes of Sub Mariner ,
We see an almost frustrated set of faces of the originals; Thor, Banner , Captain America, Scarlet Witch, Hawk eye as each potential member signs up for auditions in a near America's Got Talent or American Idol like submission, taking a number and so forth.
It's been a long day for each of these heroes as our hero of charm and charisma Tony Stark aka Iron Man chimes in and says " We'll I think that about wraps it up, it's been a long day....
Meanwhile cut scene to the very irritated and over looked wasp and ant man as tiny renditions of themselves.
What about us !
too which Tony obliviously startled by their presence takes notice
Wasp commences too stunning and shocking Tony Stark in a way that only Robert Downy Jr can be stunned and startled as she stings him and chases him down we see Tony Stark reluctant to hit a Lady while threatening to hit her with his impulse blasters...
And finally Tony Flies off in the suite trying to escape the wrath of Wasp
