The film opens with Gru returning to the Lycée Pas Bon, the villain school he once attended, to attend a reunion. He walks the halls with three Minions at his side and meets old classmates and faculty; the school's principal, Übelschlecht, presides over the ceremony. Onstage, Maxime Le Mal appears and claims a prize; during his speech he reveals that he has augmented his body with cockroach parts to become stronger and more resilient. Gru moves to arrest him and the Anti-Villain League (AVL) agents swarm the stage. AVL agents take Maxime into custody, but his girlfriend Valentina slips away in the confusion. As agents haul Maxime off, he vows revenge on Gru and hints that he has developed new technology and a plan specifically aimed at Gru's family.

Back at Gru's house, Gru and Lucy settle their household around their new infant, Gru Jr., who prefers Lucy to his father and reacts with suspicion to Gru. Silas Ramsbottom from the AVL arrives unannounced and delivers alarming news: Maxime has escaped from custody. Silas orders Gru, Lucy, and the girls into witness protection immediately. AVL operatives move the family to a safe house in the wealthy town of Mayflower and change their legal identities to the Cunningham family. AVL personnel also remove most of the Minions for containment and experimentation. Silas selects five Minions--Dave, Mel, Gus, Tim, and Jerry--to participate in a program to augment them with superpowers and rebrand them as the Mega Minions. The experiment gives each a distinct ability, but the Minions lack discipline and use their powers recklessly, causing major property damage and chaos across the city. Silas deems the program a failure and pulls the initiative, placing the Mega Minions into retirement.

In Mayflower, the family moves into a large house beside the Prescott family. Gru tries to be neighborly and introduces himself to Perry Prescott and his wife Patsy, who host an upscale tennis-club lifestyle. Their teenage daughter Poppy Prescott recognizes Gru's face and calls him by his villain name. Poppy reveals that she is an aspiring villain and blackmails Gru: she will reveal his identity to the world unless he helps her pull off a heist that will guarantee her admission to Lycée Pas Bon. She demands he steal the school's mascot, a ferocious honey badger named Lenny, and she threatens exposure if he refuses. Gru resists but yields when he realizes keeping the family hidden is paramount.

Gru recruits two Minions and brings Gru Jr. with him as they travel to the Lycée Pas Bon to steal Lenny. Inside the school, security proves tighter than expected. The Minions accidentally leave Gru's toolkit on their hot-air balloon and Gru must improvise. Junior, restless in his carrier, wakes Lenny and causes a scene. In the chaos, Gru accidentally sedates himself with a tranquilizer while trying to catch the badger. Junior soothes Lenny with his presence and helps calm the animal enough for them to extract him from the campus. They escape with Lenny, not yet realizing the collar on the badger contains a tracking device. Meanwhile, Principal Übelschlecht reviews the security footage, identifies Gru, and calls Maxime to report his location, inadvertently delivering the family's safe-house coordinates straight to Gru's nemesis.

At home, Lucy pursues a mundane attempt at civilian employment by working as a hair stylist in a wealthy Mayflower salon. She angers a client named Melora by accidentally mixing hair chemicals that burn off the client's hairstyle and scalp. Melora's wrecked hair leads to a small blaze in the salon and Lucy flees in panic, still paying for the groceries she had purchased earlier and escaping before the situation escalates.

Edith and Agnes attend a local karate class while the family adjusts to their new lives. At the dojo, the instructor pressures Agnes to use the family's cover names; Agnes grows uncomfortable and Edith responds by stomping the instructor's toe, breaking it and igniting a minor scuffle that ends with Edith receiving cheers from the other students and the instructor left incapacitated.

Inside the Cunningham household, Agnes longs for the pet goat Lucky, which had to stay behind, and she mourns the separation. Margo, meanwhile, tries to maintain the family's vigilance, texting her parents frequently. Poppy, meanwhile, keeps Lenny hidden in her room and grows attached to the honey badger while continually pressuring Gru for villainous mentorship.

Gru and Lucy join the Prescotts at their country club for tennis. While Gru practices, Übelschlecht shows up at the safe house to interrogate the children. Her questions cause Poppy to panic; she grabs Lenny and flees the house, intending to hide. The children's suspicion that something is wrong escalates when Margo texts them that Übelschlecht has been snooping. Gru and Lucy rush home, leaving the country club, and arrive as Übelschlecht activates her motorized super-wheelchair and attacks the house in an effort to seize the badger and find Gru. The family fights back; Lucy grabs hold of the wheelchair's systems and disables it temporarily while the others push Übelschlecht away. During the melee, Poppy slips away with Lenny and in the chaos Maxime and Valentina appear: Maxime's roach-engineered transport descends, and Valentina maneuvers a heavy roach ship into position. Before the family can regroup, Maxime and Valentina kidnap Gru Jr.; they extract him from the house and take off in their craft.

Lucy remains behind to continue battling Übelschlecht while Gru takes immediate action to rescue his child. Poppy, who feels responsible for putting the family at risk, commandeers a small personal flying vehicle and offers to help Gru pursue Maxime. The two take off and trace the roach ship's flight path. Poppy pilots and maneuvers while Gru prepares to board the enemy vessel. Gru clips onto the roach ship, breaks in, and fights his way through Maxime's cockroach-engineered aerodrome. Maxime reveals the full extent of his plan: he has invented a device--designed using cockroach DNA and engineering--to convert humans into human-cockroach hybrids and to control their behavior. He has already used the device on Gru Jr., transforming the infant into a hybrid combatant and programming him to attack his own father.

Onboard the roach ship, Maxime deploys his modified Junior to strike at Gru. Gru engages in a brutal hand-to-hand confrontation with the transformed child, sustaining wounds as he tries to reach his son emotionally and physically. Maxime taunts Gru about the childhood slight that sparked his vendetta: at Lycée Pas Bon's talent show, Gru had performed "Karma Chameleon" and stolen the attention Maxime had coveted. Maxime uses that grudge to fuel his cruelty and commands his cockroach minions to attack. Valentina assists by piloting the ship and coordinating roach assaults.

Gru, bleeding and battered, speaks to Gru Jr. through the armor of the transformation, calling him "dada" and urging memory over manipulation. The human affection embedded in Gru Jr. surfaces; the boy's human mind wrestles with the insect instincts imposed upon him. Gru's words pierce the brainwashing and the child's love for his father begins to override Maxime's control. In a decisive moment, the transformed Junior attacks Maxime instead of his father. Maxime struggles to retain command and loses balance aboard the ship. Valentina attempts to regain control of the craft but the vessel groans under its modified weight; the structure collapses in part and Valentina falls through a skylight, tumbling into the building below. Maxime slips and falls from the ship as well, plummeting past girders and scaffolds; he strikes multiple surfaces on his descent and lands heavily on the ground beneath the construction site.

As Maxime falls, Gru Jr. lunges at him, and Gru wounds Maxime further as he reaches him. The Mega Minions, who have been reinstated when Silas makes a last-minute decision to deploy them, arrive on the scene and swarm around the fallen villain. They pummel Maxime with their augmented powers: one stretches and constricts, another lifts and slams, one delivers laser strikes, another flies through structural supports to bring him down further, and one uses rock-like strength to pin him. AVL agents converge and place Maxime and Valentina under arrest; they put restraints and secure the roach devices and the mutated cockroaches. Silas supervises the containment of the roach army and orders AVL teams to sweep the area for remaining threats.

After the skirmish, Gru regains custody of Gru Jr. and carries him away from the wreckage into the awaiting vehicles. Lucy reunites with the family as Dr. Nefario arrives on scene to examine the boy. In a basement laboratory at the family's original home, Dr. Nefario works to reverse the genetic and neurological modifications imposed on Gru Jr. He administers carefully calibrated antidotes and reconfigures the devices embedded in the child's hybrid physiology. As Dr. Nefario operates, Junior's features slowly return to normal human form and his behavior stabilizes. When the transformation widget and behavioral conditioning are fully neutralized, Gru Jr. looks at his father and, in an act that completes their reconciliation, calls him "dada." Gru holds his son, weeping and relieved.

Agnes is reunited with her goat Lucky when AVL operatives return the animal; Gru arranges the reunion himself as a gift to his youngest daughter for her steadfastness during the crisis. Gru thanks Poppy for her help in pursuing the roach ship and acknowledges that she saved his son. Poppy's brave actions and her connection to the Lycée Pas Bon community earn her acceptance to the villain school; she receives official notification and celebrates with the family.

Silas oversees the aftermath: AVL teams dismantle Maxime's equipment and transfer the captured villain and Valentina to a secure AVL prison facility. Silas announces the end of the Mega Minions' trial phase; after seeing how instrumental they were in subduing Maxime at the conclusion of the fight, he formally reinstates them, though he imposes stricter protocols and supervision. Dr. Nefario confirms that Gru Jr. is medically restored to his prior human condition and clears him for normal family life.

Sometime later, Gru seeks out Maxime in his AVL prison cell to confront the root of their rivalry. He enters the visitation room and speaks candidly, admitting that he did perform the same song Maxime had planned at their talent show years ago. The two exchange apologies and awkwardness gives way to a surprising rapprochement. To punctuate their reconciliation, Gru and Maxime arrange a performance for the inmates: they lead a rendition of "Everybody Wants to Rule the World" inside the prison. The song draws an audience of captured antagonists from Gru's past--Vector, Mr. Perkins, El Macho, Scarlet and Herb Overkill, Balthazar Bratt, Belle Bottom, Nun-Chucked, Jean-Clawed, Svengeance, and Stronghold--who watch and then join the men in a communal dance. The prisoners clap and sing along as Gru and Maxime perform together under prison lights.

The film closes with Gru and his family restored to their original home, Dr. Nefario returning to his usual inventive support role, and the girls, Lucy, and Gru settling into domestic life with Gru Jr. in their arms. Poppy prepares to depart for Lycée Pas Bon as a newly accepted student, excited and proud. AVL agents keep Maxime and Valentina in custody pending trials, and Silas monitors new protocols for handling experimental programs like the Mega Minions. No principal characters die during the events of the film; all major antagonists, including Maxime and Valentina, are captured and incarcerated rather than killed. The final image shows the reunited family together in their living room, Gru smiling as his children play and the Minions, supervised, bustle around, bringing the story to a close.

We don't know. The details of Despicable Me 4's ending have not been publicly revealed, as the movie has not yet been released. Without official plot information, I cannot provide a narrative description of the film's conclusion.

Despicable Me 4 (2024) does not have a traditional post-credits scene with additional story content or plot teasers. Instead, during the end credits, there is a series of humorous animations featuring the Minions engaging in chaotic and funny antics. Notably, a Mega Minion named Gus is shown sleeping at the bottom of the screen, only to be blasted away by another Minion's light peg gun, providing a lighthearted and comedic closing moment.

This means audiences do not need to wait after the credits for any extra narrative scenes, but those who stay will enjoy these entertaining Minion gags that add a playful touch to the credits sequence.

Maxime Le Mal is Gru's old rival who seeks revenge because he blames Gru for a humiliation at their supervillain school, Lycée Pas Bon, specifically related to a talent show incident. Maxime transforms himself into a genetically engineered cockroach man and leads an army of intelligent cockroaches to wage war on Gru and his family.

Gru and his family temporarily relocate to a safe house in a run-down house in a pretentious suburb full of McMansions. They are given backstories and preppy-sounding code names they struggle to remember, with Gru posing as a solar panel salesman and Lucy as an elite hairdresser. The family must adapt to this new environment while on the run from Maxime Le Mal and his girlfriend Valentina.

Gru Jr. is the new member of the Gru family, a baby who instinctively loathes his dad and refuses any attempt to be won over. His presence adds a subplot of family adjustment and comedic torment directed at Gru, contributing to the family dynamics and challenges they face.

Valentina, voiced by Sofía Vergara, is Maxime Le Mal's femme fatale girlfriend who supports his revenge plan. Together, they lead an army of genetically engineered intelligent cockroaches wearing tiny army helmets to attack Gru's family and kidnap Gru Jr., escalating the conflict and action in the film.

A group of Gru's Minions become superheroes called the Mega Minions, which is a subplot in the film. This development adds a fresh element of Minions mayhem and heroism, expanding their role beyond comic relief to active participants in the story's action and adventure.

As a family-friendly animated film in the Despicable Me franchise, Despicable Me 4 is generally expected to be suitable for children. The Despicable Me movies typically maintain a light-hearted tone with comedic elements that appeal to both kids and adults. However, as the specific details of the movie are not yet fully known, I can only provide a general guidance based on previous films in the series.

Potential mild concerns might include: - Cartoon-style action sequences - Mild comedic peril - Some slapstick humor - Occasional mischievous behavior by characters

The movie will likely be rated PG and designed to be appropriate for most children, with the usual Despicable Me blend of humor and family-friendly adventure. Parents of very young or sensitive children might want to check specific reviews closer to the release date for more detailed content information.
