>>9975750War Machine is an interesting one due to the unclear, voluntary? choices Japanese toy companies are following with American IP. It's not just DC. Deadpool 2 opted with the toy guns loophole but War Machine, they're all bullet shooting guns (and missiles which are ok probably, it's dumb). But then again, they are not handheld guns so does it matter?
Side note Sentinel has an original War Machine coming but guns on him all look futuristic sci-fi guns or beam weapons, rail guns etc.
