Backstory and Events Edit
The Deavor siblings' backstory revealed that their father worked regularly with superheroes, even setting up a private line which had been used to call them. Late one night, the Deavors' home was broken into by burglars, but when Deavor picked up the phone to attempt to call supers, it was disconnected, as this was during the long period where supers were deemed illegal. After hanging up, Deavor was shot to death by one of the burglars. His wife (Winston and Evelyn's mother) passed away months later, having been heartbroken over the loss of her husband.
Winston, a superhero superfan, long believed that the loss of his parents could have been prevented if supers were legalized. Evelyn, however, was much more cynical, as she blamed her father for not taking himself and his wife to the home's safe room. She mostly blamed supers for the deaths of her parents, and while Winston was organizing a publicity stunt in his plan to change people's opinions on supers and legalize them again, Evelyn had turned heel and was secretly working as a villainess in her quest to make supers permanently illegal.
The film's events saw Bob (Mr. Incredible) and Helen Parr (Elastigirl), along with Lucius Best (Frozone) invited by Winston, who gave the details of his publicity plan, which was centered on Elastigirl. Throughout the film, Elastigirl found herself dealing with a mysterious villain known as the Screenslaver, who used hypnosis through TV screens and other monitors to cause chaos and discredit superheroes. All the while, Evelyn and Helen formed a bond due to the former bringing up her tech skills and Winston's knack for salesmanship, with Helen telling Evelyn to go after what she wants in life. As for the Screenslaver, Elastigirl managed to save an Ambassador from his clutches, and was later able to track his signal; finding him in an apartment complex. After a chase, Elastigirl subdued the Screenslaver and unmasked him, revealing him as an unknown pizza delivery man who had no memory of what had happened.
Reveal and Downfall Edit
After the Screenslaver's capture, Evelyn spotted Elastigirl looking over the scene, as she noticed something was amiss due to how easy it wasy. Evelyn told Elastigirl to solely focus on the fact that she captured the bad guy, only for the latter to realize that the "Screenslaver" was under control himself, and she took out a set of hypnotic goggles from under the mask. It was at that moment that Evelyn placed the goggles on Elastigirl, revealing her villainous personality as the true mastermind behind the Screenslaver scheme.
Later in the film, Elastigirl woke up tied to a chair and was encountered by the vengeful Evelyn, who voiced her bitterness towards supers. She stated that her father's dependence on superheroes made him weak (and that the others were weak as well for believing in supers) and led to his and her mother's deaths, while also blasting Winston and referring to him as a child for his belief in superheroes. The villainess revealed her true plan: to have superheroes declared illegal for good, and it included placing all of the supers under hypnotic control. Evelyn lured Mr. Incredible to the Deavor home under the pretense that his wife had been compromised, resulting in Mr. Incredible fighting against his hypnotized wife, with the fight ending with Elastigirl placing the goggles on her husband.
Evelyn also sent other supers to the home in an attempt to capture Violet, Dash, and baby Jack-Jack (whose many powers were just coming to the light), only for Frozone to appear and fight the hypnotized supers. Frozone ended up with the goggles on as well, leading to the kids escaping and heading to Winston's hydrofoil, the Everjust, where Evelyn would unleash the centerpiece of her villainous plot. After the Ambassador signed the document legalizing supers, Evelyn instructed Mr. Incredible, Elastigirl, and Frozone to wreak havoc, only for the trio to be freed by the kids. Meanwhile, Winston confronted Evelyn regarding her actions, only for Evelyn to claim that what she was doing was for her brother's own good. After the other supers' goggles were removed and destroyed, Elastigirl faced Evelyn once again, but became loopy due to the lack of oxygen. Despite this, Elastigirl fired a flare gun at Evelyn and sent her off the boat, only to later save her—despite the villainess' refusal. After the rest of the family saves the boat from crashing into Municiberg (which was her intended plan), Evelyn ended up handcuffed and arrested, while callously defending her stance against supers despite being saved by one of them.
