Have you heard of the russian superhero-movie "Guardians"? [View all]
It's based on a soviet-era superhero-comic that in turn was a rip-off of the Fantastic Four. Each superhero represents a region of Russia:
Sexy blonde water-woman is the european part. (Not Caucasus. Native Caucasians are dark-haired. More like Ukraine and Belarus.)
Black-whirlwind-ninja-dude is the far-eastern part.
And there is an Earthbender and a Were-Bear with a gatling-gun, but I don't know what regions they represent.
The movie launched in Russia in February 2017 but got bad reviews for boring story and bad CGI. The CGI is actually not that bad considering a budget of $5 million, but there's not much leeway if the story is bad.
And the story is... Super-villain and his army of show up out of nowhere and attack Moscow and the russian army is outmatched. The superheroes must save Russia from the invaders. With lots of punching and splosions and swagger. But this time it's personal because the super-villain is (I guess?) also the guy who gave them their powers.

After a great start, the movie bombed at the russian box-office and further releases seem unlikely.
