Arriving in The Phantom Zone, Batman witnesses the harm his selfishness has caused to everyone and slowly accepts his greatest fear when Robin, Barbara, and Alfred decide to come to his aid. Believing Batman to be incapable of change, Joker zaps him to the Phantom Zone, before stealing the Batcave's stash of confiscated bombs and heading for the city's Energy Plant. Batman soon finds himself able to trust and rely on the others, allowing them to defeat Sauron, but upon reaching Wayne Island, he ditches the team out of fear of losing them like his parents, choosing to confront Joker alone. Realizing that the city does still need him, Barbara releases Batman and Robin and reluctantly teams up with them to stop The Joker, with the team joined by Alfred.
While the Projector is being seized as evidence, Harley Quinn, the only villain who The Joker didn't have surrender, steals it back and uses it to free The Joker, who unleashes the villains trapped within The Phantom Zone to cause havoc upon Gotham, including Lord Voldemort, King Kong, Sauron, the Wicked Witch of the West, Medusa, Agent Smith and his clones, the Daleks, the Gremlins, and The Kraken. Annoyed at his recklessness and suspecting that Joker wanted this to happen, Barbara locks up Batman and Robin. The pair manages to recover the Projector from The Fortress of Solitude, before breaking into Arkham Asylum and using it on The Joker. Despite realizing that this makes him no longer relevant to the city's safety, Batman suspects his arch-rival is up to something and decides to stop him by banishing him into the Phantom Zone, a prison for some of the most dangerous villains in the LEGO multiverse.Īs he plots to steal Superman's Phantom Zone Projector, Alfred intervenes and advises him to take charge of Dick Grayson, whom Bruce had unwittingly adopted as his ward during the gala, to which he eventually agrees and fosters Dick as Robin. The Joker crashes the party with the rest of Gotham City's villains but has all of them surrender to the police. The following day, Batman attends the city's winter gala as his alter ego, Bruce Wayne, to celebrate the retirement of Commissioner Gordon and the ascension of his daughter Barbara as Gotham's new police commissioner, but is infuriated when she announces her plans to restructure the city's police to function without the need of Batman. During a mission to prevent The Joker from destroying the city, Batman hurts his arch-rival's feelings by telling him he is not as important in his life as he thinks he is, leading Joker to seek the ultimate revenge on him.
Three years after saving The LEGO Movie universe with Emmet and Wyldstyle, Batman continues fighting crime in Gotham City.
