In memory of Denny O'Neil, who passed away a few days ago, many people have been discussing his famous Batman run. But as an Iron Man fan, I'm almost duty-bound to point out that he was also responsible for the "Deliverance" arc -- which ended with issue #182, the very best, most emotional issue of Iron Man that has ever been written. Pictured above? Captures from my favorite page, which punches me in the gut every time I re-read it (which is often, I'm not gonna lie).

Tony originally built his armor to protect his broken heart -- in more ways than one.
