He is the master of sea creatures and a member of the Justice League; a hero caught between the surface world and his ocean world of Atlantis. Unfortunately for Aquaman, he is also the butt of many superhero jokes in mainstream media, ranging from Family Guy to Robot Chicken (he needs to be near water for him to be useful, apparently). With the new 52, Geoff Johns had the daunting task of making Aquaman relevant. After a year and a half, he has succeeded so far. Now, this title and Justice League crossover to face off against Aquaman’s half-brother, Ocean Master.
After a year and a half as a team since the 52 reboot, their roster has not changed. Besides Hal Jordan a.k.a. Green Lantern leaving the team, their core has consisted of a six member team: Superman, Batman, Wonder Woman, Cyborg, Aquaman, and Flash. However, with promotions for a new Justice League (of America) from DC Comics, change seems to be coming very soon.
