Sometimes it's not safe to go in the water, even for Aquaman.

He along with Superman, Batman, Wonder Woman and the rest of the Justice League have more than Great White sharks to worry about in the sea when an army from the sunken nation of Atlantis attacks in the five-issue story line "Throne of Atlantis" starting in December in Justice League issue 15 and continuing in the pages of Aquaman.

It's all part of the second year for both DC Comics books written by Geoff Johns, and Justice League in particular will be showcasing new relationships (like the romance between Superman and Wonder Woman), new members in Shazam and the Atom, and a new rivalry between Batman and Aquaman.

"It's all about progressing the team and the members and the reality and the perception of what the Justice League is in the DC Universe," Johns says.
