If its actually from the show, i'm going with alternate universe crossover. Look at some of the weirdness. Storm has Snowbird's cape. I assume that's Bill Foster in that Giant Man suit. Its Rogue in a variant of Ms. Marvel's costume. Weird.
Also, I watched the end of this season today. You'd think Odin or the dwarfs could have done something about the shield. and that the rest of the Avengers would have been sympathetic about its destruction. Also, I dont like that Cap got punked by the skrull.
I just noticed that Wolverine has a Guardian-esque maple leaf pattern on the side of his uniform in the picture.
