I believe Hawkman's future (as a character) becomes more secure with each passing issue (although I don't know what sales are like). Why? His Rogue's Gallery. Three years ago, who even knew he had one? Now they are already larger and cooler than Superman's entire collection of enemies. Then again, even Marsha Mallow is cooler than Superman's enemies....
The creative team has made it clear: anyone who's fought Hawkman even once is fair game. I almost fainted (I'm that kind of guy) when Thought Terror appeared in this month's issue.
For those who don't know him, I stole, er, unearthed from the DC Message Boards this synopsis of his only previous appearance (Flash #4!):
THE THOUGHT TERROR
The Thought Terror was working as a seer in the Futurists Club, where he would interpret the future for people with readings that seemed to always come true. One man was told he would start drinking and then be hit by a car. Carter Hall (better known as Hawkman) came upon the staggering man on the street and managed to prevent him from being run over. Taking the man to his home, Carter discovered that he wasn't drunk at all. Meanwhile, the driver of the car that nearly hit the man reported back to the Thought Terror that he had failed, which infuriated the villain. He had been making a fortune reading people's futures (at $100 per question), when he was actually just hypnotizing them into doing what he says will happen, along with a little outside help to spur things along (such as the car).
Carter, intrigued by what has happened with the man, sprang into action as Hawkman. Taking with him a gladiatorial net, Hawkman captured the driver of the car and took him to his headquarters, where the driver spilled all the information about the Thought Terror's operation. He said that he and the other lackeys didn't revolt against the Thought Terror because they were afraid that they would be hypnotized and killed.
Hawkman took to the skies again, this time with a metal shield, after being warned to watch out for the Thought Terror's mesmerized men. As he dashed into the villain's lair, he was assailed by the men, who were hypnotized to not feel pain, so they couldn't be felled by normal means. Hawkman was taken down and imprisoned fairly easily. The next morning, Shiera came to Carter's house and the Thought Terror's man told her where he had gone. When Hawkman noticed her outside, he flashed a message with his reflective shield that warned her about the Thought Terror and told her to bring a blowtorch to cut the bars of his cell. The Thought Terror entered just as he had finished his coded message and took his shield away, saying that Hawkman would die of starvation or madness in that cell.
That night, Shiera brought the blowtorch, and gave it to Hawkman through his cell window. The hero proceeded to burn through the hinges on the door, freeing himself. He then started tying up the mesmerized men one-by-one, and discovered that his shield had been taken to the Thought Terror's private room. After retrieving the shield, he held it in front of him as he advanced on the Thought Terror, who was attempting to hypnotize the hero into thinking he was a harmless idiot. Unfortunately, the Thought Terror saw his own mesmerizing reflection and lost his own reason. The underlings came out of the spells they were under and returned to their own lives, as did the driver and the first man. The Thought Terror was sent to a lunatic asylum.
