Target offered an exclusive 3 pack last year that aligned itself with the Avengers: Age of Ultron movie. While the figures aren't quite what you see in the movie, it is a cool set and came at a perfect time. While Marvel Legends collectors probably have plenty of Hulk figures, the ghostly, all-white Vision, is a great addition to any collection.
The Ultron figure is more reminiscent of his comic book style, and not the movie caricature. Still, a pretty cool 3 pack.
