I think the reason why we don't see any other patriot super heroes from other countries is because America's sense of unified country is, at the end of the day, very rare in the rest of the world.
In Europe there are countries that have nationalist movements all over the place. They all want independence, even though for some of them would mean that they'd be tiny countries with only a few hundreds of square kilometers.
The two best examples I can think of are England and Spain, the latter being where I come from. Germany and Italy have their issues too. I'm not so sure about France. But don't get me started with Eastern Europe!
I think that's why most people find America's patriotism so insufferably annoying. I don't really have a problem with it, but I know I'm the exception. Probably because my mother is American, so I can't help having a soft spot for American culture despite the anti-Americanism that surrounds me.
Regarding Spain, our comic book industry has never been rooted in action and adventure stories. It's always been about satiric humor: "Mortadelo y Filemón" (Best Spanish comic books EVER!), "Zipi y Zape", "13 Rue del Percebe", "Anacleto, agente secreto", etc...
The only exceptions to the rule are two stories about Middle Age heroes: "El jabato" and "El capitán Trueno" ("Captain Thunder" And you thought "Captain America" was cheesy...)
Those two were very popular from the 50s to the 70s, but they started to loose popularity during the 80s. And during the 90s they almost dissapeared due to the Japanese manga "boom". Only "El capitán Trueno" keeps doing some books from time to time and have some nostalgia-rooted niche popularity. Maybe that would make a good movie, even though I doubt many people would be really interested.
