This beautifully detailed figure is from the recent "Avengers" lineup that also included the Scarlet Witch, Loki, and Iron Man (from Heroes Reborn).  Thor also came with a stand that included "lightning", which encircled him.  Please also note that the figure was extremely hard to find even when the assortment was otherwise plentiful, resulting in that the only one I could find had red paint on his right hand and a bent hammer, but hey, I got one!  So if you see one, snag him!
