Also, stewmurray47 on YouTube managed to procure one of these figures and
did a full video review of it. Also, he is now aware that this is Superman's alternate costume so his one complaint about the figure is moot.
I plan on doing either a video or pictorial review of Injustice Batman as soon as he comes in. I managed to snag one on eBay as well.
