The Incredibles

During the golden age of superheroes, Bob Parr — known as Mr. Incredible — is a beloved hero who stops a suicide attempt mid-chase only to inadvertently cause collateral damage while fighting the villain Bomb Voyage. His overeager fan Buddy Pine tries to help and ends up with a bomb attached to his cape; Bob saves Buddy but the bomb destroys a section of train track, forcing Bob to stop a runaway train. Shortly after marrying fellow superhero Helen (Elastigirl), Bob is swept up in a wave of lawsuits filed by people harmed during superhero interventions. The resulting public backlash leads the government to launch the Superhero Relocation Program, forcing all superheroes into anonymity and civilian life.

Fifteen years later, Bob and Helen live in suburban Metroville with their three children: shy, insecure Violet, hyperactive Dash, and infant Jack-Jack. Bob chafes at his unfulfilling job as an insurance claims adjuster, quietly bending rules to actually help policyholders. He moonlights as a vigilante alongside his old friend Lucius Best (Frozone), the two of them monitoring police scanners and sneaking out on covert hero activity. After Bob physically injures his overbearing supervisor during an office confrontation, he is fired. That same evening, a mysterious woman named Mirage contacts him with an offer: travel to Nomanisan Island under cover of secrecy and destroy a rogue combat robot called the Omnidroid. Desperate for purpose, Bob accepts.

The mission reignites Bob's sense of identity. He begins secretly training, loses weight, and recovers his old physique. He visits the eccentric superhero costume designer Edna Mode, who creates an updated suit for him — and, unbidden, new suits for the entire family. Bob returns to Nomanisan for follow-up assignments, but during one mission he discovers the truth: Mirage is working for Buddy Pine, who has reinvented himself as the supervillain Syndrome. Having been rejected as a sidekick by Bob years earlier, Buddy grew obsessed with revenge. He became wealthy engineering weapons that mimic superhero powers, and has spent years luring retired superheroes to the island to be killed by successive Omnidroid prototypes — using each hero's defeat to improve the robot's design.

Syndrome captures Bob. Meanwhile, Helen discovers Bob's secret activities through Edna and uses a tracking beacon in his suit to locate him. She borrows a jet and flies to Nomanisan Island to mount a rescue, but Violet and Dash stow away on board. Despite knowing children are aboard, Syndrome orders the plane shot down with missiles. The family survives the crash into the ocean, reaches the island, and eventually reunites with Bob after Violet and Dash demonstrate their own emerging powers fighting off Syndrome's guards.

Syndrome launches the final phase of his plan: sending the Omnidroid to Metroville to rampage publicly, at which point he intends to arrive as a fake hero, defeat it via remote control, and retire as a celebrated savior — then sell his inventions to the public so that, in his words, "everyone can be super." The Incredibles and Frozone pursue the robot through the city. The Omnidroid's own artificial learning systems identify Syndrome's remote control as a threat and disarm him, turning on its creator. The family works together to combat it, and Bob ultimately destroys the robot by ripping out its power core.

Returning home in triumph, they discover Syndrome has broken into their house and kidnapped the infant Jack-Jack as an act of revenge. As Syndrome rises toward his jet with the baby, Jack-Jack's latent superpowers spontaneously manifest — he shapeshifts and burns Syndrome — and escapes his captor's grip mid-air. Helen swoops in and catches the falling infant, while Bob hurls his car into the engine of Syndrome's jet. The plane explodes, killing Syndrome when his cape is sucked into the engine — an ironic callback to Edna's warning that capes are dangerous.

Three months later, the Parr family has reclaimed their superhero identities. Their peace is immediately interrupted when the supervillain the Underminer emerges from beneath the street. As a unit, the family dons their masks and suits up, ready to face the next threat together.
