Hal's on the cover of "JL: Last Ride" #4:
The Justice League disbanded when their last mission went terribly wrong, and Martian Manhunter paid the ultimate price. But the team learns that time is a circle, and their last mission on Apokolips holds more than just the key to protecting a war criminal and completing their mission, it tells the story of how we lost J’onn…and why Superman holds Batman responsible!
Looks like Hal will play a bigger role in what’s to come than just a cameo which is nice.
