Thor is a pretty tough guy. In the MCU, Thor frequently appears to be the strongest among the Avengers (managing to bust up Iron Man's suit without breaking a sweat). That makes sense - humans are always pretty lame compared to superheroes. 

However, Thor seems to be even stronger than the average Asgardian - as evidenced in both of his eponymous movies where he single-handedly defeats hordes of Frost Giants and Dark Elves. This too is hardly unexpected, as he's the heir to the throne of Asgard, son of the Allfather, and wielder of Mjolnir. But still, I find myself asking... why?

Is he genetically superior in some way? Did he eat more of the [Apples of Idunn](http://marvel.wikia.com/wiki/Golden_Apples_of_Idunn) than his peers? Does the Allfather's magic run through his veins, granting him greater abilities than a footsoldier of Asgard?

As a note of curiosity, his pals in the movies (the only other heroes who get names at all) who accompany him on his many misadventures to the Nine Realms seem to be better than average as well. Sure, this could be chalked up to "they're protaganists, get over it" - but I'd like a better explanation.

http://scifi.stackexchange.com/questions/55697/how-strong-are-asgardians discusses Asgardians' strengths in general, but only briefly mentions Thor specifically. I'd prefer an in-MCU answer if possible.
