The World's Greatest Heroes of Tomorrow are here! Now with a few fresh faces and a newly constructed Watchtower, the Justice League are back to being a well-oiled crime-fighting machine!

JUSTICE LEAGUE BEYOND: POWER STRUGGLE is collected here in its entirety for the first time, written by Christos Gage (AVENGERS ARENA).
