Did you ever see a character and say to yourself, "this guy is too cool for words. Why aren't they a bigger deal than they actually are?"
Two of my favorite DC characters were always in that category: the villainous Kobra and Pete Morisi's sixties hero, Peter Cannon, Thunderbolt.
First, check out the house ad up top for his first Post-Crisis series. Pretty groovy, eh?
One thing that always blew my mind about Thunderbolt was how he's the only superhero I can think of where his archenemy is a real historical person: Queen Evila, the Ancient Egyptian immortal sorceress, was outright stated to have been Hatshepsut II, who in real world history was the only female Pharaoh other than Cleopatra.
Peter Cannon, Thunderbolt has the extreme distinction of having his imitators and outright ripoffs be more famous than he is. First, there's Iron Fist, who Chris Claremont has flat-out said in every single interview given on the topic was a character "inspired" by Peter Cannon, Thunderbolt: their origins are the same, the American baby raised in Tibet after a plane crash. And everyone knows the role the Charleton heroes played in the creation of the Watchmen, with Dr. Manhattan as an expy for Captain Atom, Rorschach as the Question, and so forth....and Ozymandias was the inspiration and starting point for Ozymandias, with his tremendous speed, martial knowledge, and mystic obsessions.
The common "Marvel Zombie" attitude is that DC is staffed by old phogeys that are totally out of touch with popular culture. And every time I am inclined to think that's an unfair and undeserved stereotype DC does something that reminds me of how totally legitimate it is, by their total failure to cash in on the pop culture zeitgeist.
When Star Wars and Battlestar Galactica was a big deal, DC unveiled their sorry afterthought, Gerry Conway's Atari Force. Marvel, meanwhile, responded to the Star Wars craze by doing Star Wars comics. Then you have DC's years-too-late attempts to cash in on the Martial Arts craze, featuring a lily-white dude (I'm just saying!) named Richard Dragon.
A few recent failures to capture the imagination come to mind. For instance, Barry Allen was a police scientist years and years before the public fascination with scientific/forensic police work and had been dead for decades by the time of the CSI craze. Though in that case it's probably for the best that Barry stayed dead, if Barry was alive, he could have a lot of cachet to do something audiences like.
The second example I can think of is the current popularity of Avatar: the Last Airbender. I'm sure someone must know of the untapped potential here! My God, Peter Cannon could be DC's answer to Avatar! Avatar was a series about a hero raised by Tibetan monks that constantly reincarnates over and over. That's the same with Thunderbolt, also called Vranya (which is a real Indian word, incidentally).
