Chief creative officer for DC Entertainment Geoff Johns announced this past weekend that he will be writing a new Aquaman ongoing series scheduled to launch sometime after Flashpoint. Check what he said:
"Mera will be a staple in the series. She'll be right next to Aquaman"
Johns also added: "Brightest Day had a pretty straightforward superhero Aquaman story. That was to get him and Mera and Aqualad and Black Manta and everybody back on stage [...] but where we go in the book will surprise some people" Visit Newsarama for more details.
