The upcoming brawl, Avengers: Battle for Earth, between Earth's Mightiest Heroes and the Skrulls gets an official trailer during e3.
The motion-sensitive game for Kinect and Wii U features 20 playable heroes and villains, out of whom confirmed playable are Hulk, Iron Man, Captain America and Loki as playable while the rest have only been seen in the trailer. Add onto that a four move functionality that'll be triggered by your movement and Avengers: Battle for Earth could be the way you get ready for spandex by the next Comic Con.
There's an easy way to check for a skrull, though. Just ask if they love you. If they respond, "he loves you," and then becomes a spinning column of fire, you've got a skrull.
