Thanks to Seibertronian Bounti76, we have confirmation that Legion Hound at least has finally been found in the US at Ross, and just like Cogman, he has been found at a store not normally known to carry new or unseen product. What this appears to mean is that the final waves of The Last Knight toys appear to be making their way from storage areas to the shelves of stores finally, only not quite the stores we expected.
Ross and TJ Maxx have proven to be stores this past year that have gotten some fairly good product, seeing as how several figures that have evaded toy hunters of all ages keep showing up at these stores. So if you have one of these stores or one like it, or even like Ollies, you should go check them out!
