Hard to choose, I got my 1st 3 volumes of Hellboy back in '00-'01 when on deployment to to Gulf. Was mesmerized by the story and the art. Don't remember the issues, but when Hellboy is to fulfill his fate and unlock the door to hell with his hand. But Hellboy is raised as an American, and we don't do anything we don't want to do. So he says "No" and bust those horns off. The 3 wiseman are baffled that he could choose and then to say no... Why that was just perfect! Read that almost 14 years ago, still see the frame of him breaking his horns off.
