DC has announced that all of its New 52 titles will be labeled with a special "WTF Certified" slug in April. Teases for the storylines include "Booster Gold reappears while an entire team disappears," and "One team is trapped in a bottle while another is changed completely."
DC also leaked more teasers to Buzzfeed:
"Some heroes change their colors and others change allegiances.
Pandora Battles to the Death.
A close encounter of the Dark Knight kind.
There’s a new, old Creeper and some old New Gods.
One hero quits, and another hero dies."
