Steve Rogers studied fine arts before becoming Captain America, so why not give him an artist outlet? In Steve Roger's American Captain (a play on Harvey Pekar's American Splendor and James Kochalka's American Elf) Cap starts keeping a diary comic as he tries to adjust to life in the 21st century—a world filled with gods, monsters, and iPhones.
The brilliance of American Captain is that it reads as a typical diary comic, capturing the mundanities of Steve Rogers' daily life rather than his adventures fighting evil. He's not punching out Nazis or aliens; he's coping with the unfamiliarity of a world that changed while he was frozen in ice and the difficulty he has in relating to his teammates. And, like so many autobiographical comics, it's often sad and awkward, with occasional moments of sweetness.
You can see a few of the comics below, but then go read the entire series and following the comic on Tumblr.
