Hasbro 2017 Avengers 6″ Action Figures
This set has quite a few figures including a Black Widow figure. You’ll be able to find these probably pretty easily at a local toy retailer. Included in this set are Hulk, Iron Man, Captain America (With Shield), and Black Widow (with batons).
There are also 2 that come with something extra. These figures do actually look a bit different from their regular counterparts and also come with more accessories. There’s a Captain America figure with a motorcycle and an Iron Man figure that comes with extra armor to go over the figure. I think it’s supposed to resemble Hulkbuster but kind of misses the mark just a bit. I could be wrong but that is what the box art shows.
