Unfortunately they soon removed the image of Beware the Vulture by request to keep the identity of the character a mystery, even though it is revealed in the International trailer for the movie.
The ATM Heist Battle set is based on the scene we’ve seen in the movie trailers where a couple of criminals try to rob a bank while wearing Avengers masks. This set is just 185 pieces ($19.99) and contains 3 minifigures – Spider-Man and the 2 masked robbers. The Hulk and Captain America masks are printed on the heads for those 2. Sorry, no Thor-masked bad guy.
The Beware the Vulture set is bigger at 375 pieces ($39.99) and contains The Vulture, Iron Man, Spider-Man and the secret figure along with a van that’s heavily armed.
When LEGO allows the release of that photo, we’ll be sure to update this post.
