Game Of Thrones is more popular than ever because of the HBO show. The clans are pretty damn confusing and for this reason, fans started creating coat of arms for each family. Take for example the Stark’s. They’re known for their big ass wolves so that’s what you in their coat of arms. It was only time before the fans thought of mashing the coat of arms with another nerdy item, superheroes.
I like the slogans for the flags. Superman is the most epic and Hulk is funny.
