Justice League: Doom

The Justice League and Cyborg stop the Royal Flush Gang's attempted robbery of a diamond vault using complex technology that allows them to pass through solid objects. Meanwhile, Vandal Savage plots to start a new civilization by exterminating two thirds of the population, and it is revealed that he gave the technology to the Gang for testing. Savage hires Mirror Master to hack into the Batcomputer and steal contingency plans devised by Batman to incapacitate his League teammates lest they go rogue. Savage assembles Cheetah, Star Sapphire, Metallo, Bane, Mirror Master, and Ma'alefa'ak and offers each of them a large sum of money to simultaneously attack the League members using the plans, which he has altered to be lethal. When the supervillains agree, he welcomes them to the Legion of Doom.

As the Legion of Doom each do their part to take out the Justice League, Batman is informed by Alfred Pennyworth that the bodies of Thomas and Martha Wayne have been exhumed and are missing. At their graves, Bruce is ambushed by Bane, who beats him to near death before rendering him unconscious and burying him alive in his father's coffin.

Martian Manhunter celebrates his birthday with his colleagues in his civilian identity as John Jones. He receives a drink from a disguised Ma'afela'ak in the form of a beautiful woman, which is laced with a poison that contains magnesium carbonate. As magnesium is disruptive to Martian biology, the Manhunter struggles to maintain form while expelling the poison. Ma'alefa'ak then sets him on fire, with the magnesium continually fuelling the flames.

Cheetah ambushes Wonder Woman at a dock and scratches her in the process, infecting her body with nanomachines that affect her brainstem; the nanomachines cause her to perceive everyone around her as Cheetah. Since the villainess knows that Wonder Woman will never quit a fight, the Amazon will continue to do so until she dies from a stress-induced heart attack or brain aneurysm. The delirious Amazon proceeds to attack both Cheetah and nearby innocent bystanders.

Mirror Master lures Flash into a trap, attaching a bomb to the speedster's wrist. If Flash does nothing, tries to remove it or decreases in speed, the bomb will explode, killing everyone in a three-mile radius.

Lured to a mine, Green Lantern is targeted by Star Sapphire using Scarecrow's will-undermining fear gas. After he fails to save her hostages' lives, she exploits his fears to convince him that he does not deserve his mantle; the grief-stricken Jordan renounces his ring and resigns himself to his fate in the collapsing mine.

On the Daily Planet's roof, a former employee named Henry Ackerman is aiming to commit suicide which has attracted the attention of the media, including Lois Lane and Jimmy Olsen. After leaving a press conference as Clark Kent, Superman arrives on the scene and apparently succeeds in talking Ackerman down. However, Ackerman reveals himself as a disguised Metallo and shoots Superman with a Kryptonite bullet, critically injuring him and causing him to fall to street level from the roof.

Back at the Hall of Doom, the Legion celebrates their victory. Savage reveals that his next plan is to fire a rocket into the sun, triggering a solar flare that will destroy half of the planet and disable any technology more advanced then a steam engine. He relates his past and invites a skeptical Cheetah to test his claim of being immortal, which she does by cutting his throat; the assembled villains are all stunned when Savage gets up and the wounds heal before their eyes without leaving even a scratch. With his claim proven, he shows his teammates the rocket that will be used in his plan.

Batman comes close to accepting his fate, but a tape recorder left behind by Bane plays a taunting message from the criminal, which motivates him to break out with the memory of his father’s death. Batman realizes the League has been attacked using his contingency plans and sets out to save his allies. At the same time, Cyborg hears of Wonder Woman's predicament and sets out on his own.

Cyborg arrives on the scene of Wonder Woman's rampage, and blasts her with a sonic frequency that neutralizes the nanites. After coordinating with Batman, the two move to save Martian Manhunter, with Wonder Woman injecting him with aluminum oxide to neutralize the magnesium at Batman's instruction. Meanwhile, Batman tells Flash to run and vibrate through an iceberg in the Arctic, leaving the bomb inside and saving him. After saving Flash, Batman arrives at the collapsed mine and forces his way in, finding the broken Jordan. Batman shows him that the hostages and terrorists were merely androids. Sure of himself once more, Jordan re-establishes his will and regains control of his ring.

Wonder Woman, Cyborg and Martian Manhunter arrive in Metropolis, where Superman's health has rapidly deteriorated; paramedics have failed to remove the bullet due to his invulnerability. It is extracted by Cyborg and the Manhunter using an improvised Kryptonite scalpel laser, allowing Superman to recover.

The League retreats to the Watchtower, where Batman reveals he was the real mastermind behind the plans, and that they were originally only supposed to subdue. He also had a plan in place should the Batcomputer be hacked: a hidden tracing algorithm. The League track down the Legion of Doom and subdue them, but fail to prevent the rocket from launching and triggering the solar flare. Using the Hall of Doom's technology, the League saves the Earth by phasing it so the flare harmlessly passes through.

At the Justice League Watchtower, Superman reports that Vandal Savage has been found guilty of crimes against humanity and sentenced to life without parole by the World Court. The Justice League officially adds Cyborg to their roster, and Superman calls for a vote on whether Batman should be allowed to remain a League member. Batman defends his action and criticizes the others for not understanding the potential danger of a rogue Justice League before quitting the team outright. When Superman asks if Batman had a plan to stop himself if he were to go rogue, Batman states that the Justice League itself is his plan. With his trust in Batman assured, Superman hands him the Kryptonite bullet and teleports him out of the Watchtower.

The film was first announced at WonderCon 2011 that the JLA: Tower of Babel storyline will be adapted as a direct-to-video movie, which was written by Dwayne McDuffie right before his death.[4] The character designs were done by Phil Bourassa, the lead character designer of Justice League: Crisis on Two Earths and Young Justice. Storyboards were overseen and animated by Telecom Animation Film.[5] During the casting process of Justice League: Doom, voice director Andrea Romano expressed an interest for the cast from various media to reprise their roles as members of the Justice League.

IGN gave the film a 7 out of 10, calling it "An immensely enjoyable thrill ride, but also an occasionally frustrating and short adaptation."[6]
