Plot
Leaving off after defeating Screenslaver, the Parr family intercept robbers who have disturbed the peace. Throughout the pursuit, they did catch the robbers, but were shocked by the appearance of radioactive-powered Tsar Positron, who used to call himself Captain Electron. He killed the robbers, not caring about the loot they might have taken. They fought Positron despite reason, and with Frozone reinforcing the family, the parents and Frozone were no match. Tsar Positron then kills Mr. Incredible and then Elastigirl, causing the children to flee with Frozone.

It was now 1984, Violet married Tony Ridinger, Dash is full grown, and Jack-Jack is a junior high school. Tsar Positron had a collection of skulls and urns, with notable skulls from Syndrome and Evelyn Deavor for failing him. Tsar Positron adds Helen and Bob's skulls next to them while soldiers brought in Frozone. Tsar Positron interrogates Frozone, and provided him a torturous history of supers, who were often used for war, treated like witches, and almost exterminated during the world wars. When Frozone refused to talk despite that, Tsar Positron locked him in a tube of green radioactive water that froze on him.

After seeing some of Tsar Positron's men rob a Buy n' Large store, Violet, Dash, and Jack-Jack went to stop them, where they discovered new abilities they never used before. They had overheard a soldier talking about Frozone being captured at Tsar Positron's base, but they required help from Edna, whose location was disclosed after she revealed the base's location. The trio left, but Tsar Positron caught Edna before turning her into a giant radioactive monster. The trio freed Frozone, but the latter had terminal cancer from his imprisonment. Tsar Positron sends Edna after them, who then killed Frozone. Violet felt that a super would never turn evil, but her discovery about Tsar Positron was not what they expected.

Tsar Positron was from Severny Island, when the Tsar Bomba dropped and he suffered fallout, but he gained powers as a result. He was single at the time, but felt he now had support. However, supers were banned in the mid-60s, so he adopted the "villain" persona, an evil super. He helped out Syndrome and Evelyn Deavor fulfill their goals, but they had failed him. Even when supers were reinstated, he remained a villain. He took out any competition, including raiding prisons and taking out other unique bad guys.

During a gambling game, his men had discovered anti-matter, where he inserted the new tube into his armor, where it enhanced his powers further. Tony and Violet fought over their missing child, and Dash and Jack-Jack helped Violet get her back. They fought through the streets of New Urbem, where their baby was last seen. The trio fought Tsar Positron's men, and Tsar Positron showed up and they fled. Tsar Positron rode his motorcycle before they reached the coast, and he rammed Violet's bubble. He created antimatter doppelgangers of their parents, Frozone, and other supers they knew he had killed. Despite all of that, they managed to defeat him.

When Tsar Positron was defeated, his powers were ejected from him, and he remarked killing every single superhero before the family before Jack-Jack brutally blunts him to death. Despite Tsar Positron's actions, they buried him in pure dirt at a hill and planted a tree, which made it grew extremely quickly. Flashforward to modern-day, the Incredibles family visited the tree and when they left, Tsar Positron's helmet turned on.
