Justice League: The Games Begin

Summary
Justice League: The Games Begin is a sequel for Justice League: Doom.

Plot
Star Sapphire and the Legion of Doom attacked and defeated Indigo-1, besides stealing the seven stones of Chaos. The guardians of the universe warned Hal Jordan and the Justice League. Now, a race against time begins.

Knowing about the villains' new plan, they recruit more members and divide into seven teams. The Bat-Family, the Supermen of America, the Teen Titans, the Shazam Family, the Female Justice League, the Team Flash and the Green Lanterns. The groups went to each location: Themyscira, London, Alaska, Berlin, Africa, Egypt and Gotham.

The Bat-Family faces Gotham's most wanted led by Scarecrow. The Supermen of America face the Crime Syndicate. Team Flash faces the Rogues Gallery led by Captain Cold, who seeks revenge against Green Arrow. The Teen Titans face Solomon Grundy. The Female Justice League faces Cheetah and Arkham Knight (Jason Todd), who claims that Batman let him die at the hands of The Joker. The Shazam family faces their archenemy Black Adam. And the Green Lanterns face Gorilla Grodd and Star Sapphire.

When the heroes decided to destroy the stones of Chaos, they subsequently find themselves in another world, where the Bat-Family had to face a giant, Team Flash had to take down the wolves, The Supermen of America get haunted by some ghosts, The Teen Titans had to struggle against the Ice Giants, The Female Justice League gets chased by a dark entity, The Shazam Family faces various ogres keeping the citizens captive, and the Green Lanterns find themselves trapped when they see Mongul, who revealed to be behind the scenes.

Once the teams manage to topple their obstacles, and Superman finds out that his biological cousin Kara Zor-El is still alive, the entire Justice League reunites and free the Green Lanterns so they could finally bring Mongul down. The people could return to each planet, and the Earth was safe again. But Superman feels uneasy since he found out that Kara Zor-El is still alive, but not where he could find her. While disappointed in himself, Kal-El gets confronted and knocked out by someone who looks like him. The one who looks like Superman states "The infiltration began!".

In the post credit scene, a portal is open, revealing another Batman, another Green Arrow and another Black Canary, who find out that "their" Superman has already made his move.
