Justice League: War Edit
Batman first appeared aiding Green Lantern in a fight against one of Darkseid's minions, a Parademon. The creature then attempts to escape, but Batman grapples onto it and manages to hang on while it flies through Gotham. They end up on a rooftop, where the heroes are interrupted by the Gotham Police. They make a quick getaway and continue to chase the Parademon into the sewer. There, the creature attempts to plant some sort of bomb. Once the heroes' presences are detected, it self-destructs, but the bomb remains intact. Batman and Green Lantern then take the bomb, and head to Metropolis, where they plan to interrogate Superman to see if he knows anything about it.
After going to Metropolis, the two catch up to, Superman who is seen as a blur crashing into buildings. He finally settles in an abandoned one, where Green Lantern goes charging in, only to be seen moments later flying out of the building after being struck by Superman. The Man of Steel then zooms outside where he pins down Batman. The Dark Knight escapes and engages Superman. Despite Batman's best efforts, Superman is unharmed by any of his attacks or devices. Green Lantern then recovers and engages the Man of Steel. Angry, Superman attacks Batman and Green Lantern. In order to protect themselves, Green Lantern creates a ball of energy around himself and Batman, but Superman then sends them flying with a series of punches. After penetrating the ball, Superman zooms toward Batman and Green Lantern as though he was about to deliver the final blow, but Batman manages to say "Clark", stopping the Kryptonian, and talk him down. The three then realize they are on the same side and once again dive into the sewer.
The three then journey to an abandoned building a few blocks away from the Daily Planet, where the analyze the bomb. Batman then states that the bombs were strategically planted, and that there is the potential of a full-scale invasion. Green Lantern then disregards the idea. However, within moments, the box “activates” and opens a portal, a horde of Parademons swarming out attacking the heroes. The three then battle against them furiously. However, Superman mysteriously leaves, leaving Batman and Green Lantern fighting against them alone.
Green Lantern and Batman manage to finish of the rest of the Parademons, and soon meet up with the Flash. However, more Parademons show up, but as they brace to take them on, Wonder Woman comes and defeats them all. Superman rejoins the team and Cyborg and Shazam show up. Cyborg tells the team of the plan that Darkseid has for the world, and as soon as he finishes explaining, Darkseid appears with a large army of Parademons.
The seven heroes then attack the Parademons. Green Lantern attempts to take down Darkseid himself, but quickly fails. In the heat of the action, Darkseid fires his Omega Beams, one at Flash and the other at Superman. Flash manages to evade it, but Superman takes the blow and is incapacitated. He is then captured by Parademons and taken to Apokolips, the planet that Darkseid rules over. Green Lantern is then severally injured by Darkseid, having his arm broken by the powerful being. Darkseid then teleports away from the group, creating a large explosion.
After emerging from the carnage, Green Lantern attempts to go after Superman, but Batman tells him to stay and keep the team together. Batman then disguises himself and allows a Parademon to capture him and take him to Apokolips to save Superman.
While at Apokolips, Batman escapes from the Parademon and removes his disguise. He then sees where Superman is being taken over through Darkseid’s brainwashing under the control of Desaad (Darkseid’s right hand man). Batman stops Desaad, but Parademons arrive and attack Batman. Batman defeats them, however, a brainwashed Superman kills Desaad and goes ballistic at Batman.
Superman and Batman then return through the portal the others managed to create in his absence and manage to force Darkseid inside the portal, banishing him from Earth. Shortly afterward, they are met with the applause of a group of civilians admiring their heroism.
Later, they all make it to the White House where they are honored by the President of the United States. While the President talks, Green Lantern states to the others that they are not friends nor a team, but Batman tells him to cooperate, stating that acting as if it were so would keep the police off Batman and the Air Force off Lantern. At the end, Shazam states that the teams name is the "Super Seven", much to the embarrassment and disappointment of the rest of the team.
