Thomas and Twilight Sparkle join The Incredibles

Thomas and Twilight Sparkle join The Incredibles is an upcoming Thomas & Friends/MLP:FIM/Disney/Pixar crossover to be made by Hiatt Grey.

Plot
Public opinion turns against superheroes—also called "Supers"—due to collateral damage from their crime-fighting. After several lawsuits, the government silently initiates the Superhero Relocation Program, which forces Supers to permanently adhere to their secret identities.

Fifteen years later, Bob and Helen Parr—formerly known as Mr. Incredible and Elastigirl—and their children Violet, Dash, and baby Jack-Jack are a suburban family. Bob dislikes suburbia and his white-collar job. With his friend Lucius Best, formerly known as Frozone, Bob occasionally relives his glory days by secretly acting as vigilantes at night.

One day, Bob loses his cool and job after his supervisor refuses to let him stop a mugging. Returning home, Bob finds a message from a mysterious woman named Mirage who convinces him to become Mr. Incredible again, and gives him a mission to destroy a savage tripod-like robot called the Omnidroid on the remote island of Nomanisan. Bob finds the Omnidroid and destroys it by tricking it into ripping out its own power source.

Bob finds the action and higher pay rejuvenating; he begins rigorous training while awaiting more work from Mirage for the next two months. Discovering a tear in his suit, he visits superhero costume designer Edna Mode. Mode, assuming that Helen knows what Bob is doing, makes new suits for the entire family. Leaving for Nomanisan once again, Bob discovers Mirage is working for Buddy Pine, a disaffected former fan whom Mr. Incredible had rejected as his sidekick. Having adopted the name Syndrome, he has been perfecting the Omnidroid by hiring different Supers to fight it, adding new features on the occasion that a Super wins. Now that it is capable of defeating Bob, Syndrome intends to send the machine to the city of Metroville. There, he will secretly manipulate its controls to defeat it in public, becoming a hero himself. Later, he will sell his inventions so that everyone will become equally "super", making the term meaningless.

Meanwhile, Helen visits Edna and learns what Bob has been up to. Edna activates a beacon she built into the suits so Helen can find Bob, inadvertently causing him to be discovered and captured. Helen borrows a private plane to head for Nomanisan, but Violet and Dash have stowed away wearing their own suits, leaving Jack-Jack with a babysitter. Syndrome shoots down Helen's plane, but she and the children survive and reach the island. Helen infiltrates the base, discovering Syndrome's intentions to send the Omnidroid to Metroville in a rocket. Distraught by Syndrome's callousness when her life was threatened, Mirage releases Bob. Helen arrives and races off with Bob to find their children. Dash and Violet are spotted and chased by a number of Syndrome's guards, but fend them off with their powers before reuniting with their parents. However, Syndrome captures them, leaving them imprisoned on Nomanisan while he follows the rocket to Metroville.

The Parrs escape and travel to Metroville in a spare rocket. True to its programming, the Omnidroid recognizes Syndrome as an opponent and attacks the remote on his wrist, making him incapable of controlling it, while simultaneously knocking him unconscious. The Parrs and Frozone team up to fight the Omnidroid; the battle is indecisive until Bob comes across the remote, allowing him to control one of the robot's arms and use it to destroy its power source. Returning home, the Parrs find Syndrome, who plans to kidnap and raise Jack-Jack as his own sidekick to exact revenge on the family. As Syndrome tries to escape to his airplane, Jack-Jack's own superpowers start to manifest, and he eludes Syndrome's grasp. Bob and Helen rescue Jack-Jack, in the process causing Syndrome to be sucked into the jet's turbine by his cape, killing him.

Three months later, the Parrs witness the arrival of a new villain called the Underminer. They put on their superhero masks, ready to face a new threat.
