Guys relax, DC is just doing two-three characters each time. So they are putting a familiar on the cover, so people buy it then lesser know people as the other stories- like Starfire in issue 2. That way Superman/ Batman and Casual Fans can grab it and have a good time with it. At the same time these casual fans and "I only read Batman and Marvel" fans can become exposed to these other characters and gain interest.
At the same time shouldn't the origins have been in their #1s three years ago during the massive Reboot three years ago? If not then surely their #0s, two years ago during Zero Month, should have covered thier origins, right? I believe we should have seen all the major villains covered during Villain's Month this past year. Well apparently not.
