LEGO DC: Shazam! Magic and Monsters

Billy Batson's days are spent helping others, and a magical subway ride pulls him to the Rock of Eternity. There, the Wizard appears and tests Billy's heart to determine if he is worthy of becoming his champion. This moment marks the beginning of Billy's transformation into Shazam.

The Wizard explains the test and the fate of the previous champion Black Adam, then grants Billy the powers that will turn him into Shazam. Billy embraces the power and the age shift that accompanies it, stepping into a superhero persona. The transformation sets up his first encounters with the world as a champion.

The Wizard urges Billy to be more open to the Justice League and sends him to investigate a disturbance signaling trouble nearby. Billy prepares to engage with other heroes rather than act alone. This mission foreshadows his future role with the League.

The Monster Society of Evil launches an assault, and Shazam decides to aid Superman, Batman, Wonder Woman, and the rest of the Justice League. He helps push the Society back, proving his powers and willingness to fight alongside the League. The encounter cements his place as a potential ally in the broader team.

Impressed by his abilities, the Justice League invites Shazam to join them at the Hall of Justice. Billy declines, fearing that the team would reject him if they knew his actual age. The moment reveals his insecurity about his identity and longevity.

At the Monster Society's hideout, Mister Mind captures the League and uses a serum to de-age them into children, making them more susceptible to mind-control. Batman escapes the mind-control with Shazam's help, and Billy reveals his secret identity and recounts his origin, which helps earn Batman's reluctant trust.

Batman and Shazam locate and free the mind-controlled Leaguers worldwide from Mister Mind's control. Reunited, the team regroups and prepares to confront the Monster Society and Mister Mind again. The crisis expands beyond a single location as threats ripple globally.

The League fights their way to Mister Mind inside the Monster Society's lair. Mister Mind has transformed into a colossal moth-like creature, presenting a more dangerous and surreal threat. The heroes push toward a confrontation that could decide the fate of their world.

Mister Mind begins devouring the Rock of Eternity, growing in size as he feeds on its power. Black Adam breaks free or acts against the Wizard, unleashing magic lightning that depowers Mister Mind and sends him into space. The Rock's destruction triggers a desperate bid for rescue by the League.

The League escapes to Earth as Adam's assault threatens them. Remembering the Wizard's advice, Shazam shares his powers with the other Leaguers, boosting their abilities and restoring their aging bodies. The team prepares to face Adam as a united, empowered group.

Using their newfound powers, the League defeats Black Adam, who is depowered and reduced to a mortal man. Billy uses the shared energy to reclaim his own powers fully and rejoin as Shazam, now part of a larger team rather than a lone ally.

With the danger ended, Billy is reunited with his sister Mary and Uncle Dudley. The reunion provides him with a sense of family and belonging that he longed for, underscoring the personal cost of his heroic journey. The League's victory is celebrated with a hopeful note for Billy's future.

In a mid-credits scene, Lobo apprehends Mister Mind for a colossal bounty, leaving a setup for future confrontations and sequels. The caper hints at ongoing cosmic politics and the continuing threat of Mister Mind's schemes.
