Maxwell Lord has a stone that grants wishes. But when a wish is granted something is taken away. Diana wishes for Steve Trevor back, but in exchange she loses her powers. Thus the armor. She gets her powers back by letting him die again (it’s the sequel’s version of the first movie’s “No Mans Land” scene)
I like all of these super detailed figures. Some might have art style or color scheme I’m not crazy about but in general I find them really cool and would totally have a few if I ever threw down and tried to really have a nice man cave.
