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 rare 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. When Bob is informed that his family is dead, he grabs and threatens to kill Mirage, but relents when Syndrome calls his bluff.
