This is the work of talented Russian Artist Evgeny Yakovlev (also known as lost-angel-less). There are countless attempts by many artists to recreate superheroes in their own light sort of speak but few have mashed them up the way Evgeny did with this collection of art.
The likes of Stormtroopers telling their kids bed time stories about master yoda and such, weird but a rather funny mashup. Apart from what these illustrations resemble, the art style is what strikes me most, if you take a look at ironman, he does look funny, the exaggerated body and expressions really brings a different light on an already super, superhero.
Of course, Evgeny is a talented artist and has many to showcase on his portfolio, especially comics that dont necessarily feature super heroes but rather creations of his own.
