Mostly upcoming comics covers I find interesting, plus whatever else I want to discuss.

That's right; I'm not picking Action Comics # 1. I like this one better. Since Action Comics # 1, Superman has smashed hundreds of cars in the pursuit of truth, justice and the American way. And smashing one for the first time cannot compare to Clark telling Lois he is Superman after more than 50 years of stories. He can only do that once. Huge impact. A memorable image too. I think plenty of people who aren't big DC fans have a copy of this comic or at least remember it coming out. Maybe Lois should have figured it out long ago, but that doesn't make this cover any less great. 
When Legends of the Dark Knight first hit the shelves as "the first new solo Batman book since 1940," people noticed. Some choice talents did stints on the book. Neither of these covers can win because, like the Oscar contending actor with two great performances in a year, voters considering these will be split down the middle as to which one to pick. Ultimately, the Poison Ivy one is better. It is frightening, as she strides amongst the bats.
Many people could not appreciate this recent Green Lantern encounter with a hyper-evolved shark. I loved it. The shark on the cover has it all: cunning, ferocity, even hands, and somehow GL's ring and battery in its jaws. Oh no! Go back to this one each time Shark Week rolls around on the Discovery Channel.
On a more serious note, with the GLC having just undergone a Recharge, this cover confirmed I'd have a solid well-crafted ongoing GLC title to read hopefully for a good while to come. Good enough.
The sci-fi, romance, humor and misunderstanding common to many a story are played out here with a kiss between an attractive girl and a guy whose brain is trapped inside a robot body.
I don't know if we are meant to consider Vertigo comics, but it is a DC brand, so I'll suggest one of my favorites. Unfortunately, in scanning it, I realized that my copy is marred by a stray ink mark. That's unimportant for our purposes here. It still represents the good work that comes out of Vertigo, whether derived off Sandman or not. The woman with her broken sword leading her knights into battle is impressive.
Finally, I chose one from my collection that I don't think many people would even remember, let alone consider voting as the best. I enjoyed running across it again myself though. Since B5 has not survived as a DC ongoing, its impact might be considered minimal. I'm sure I partly kept this one so long because of my fond memories of the B5 television show. It is probably also one of the earlier comics with a JMS credit even though he is mostly working for Marvel these days. I'm wondering if the interior artist actually did the cover, so if anyone can identify the cover artist for me, let me know.
Eventually I'll get tired of these Catwoman pics. Maybe.
Glowing eyes think alike. Or something like that.
Look where you are going for once Captain Comet.
