Evelyn Deavor

Evelyn Deavor is the hidden main antagonist in Pixar's Incredibles 2. She is the brainchild behind Winston’s company, as well as his business partner. She shares her villain title with her puppet, that unwilling plays the masked villain in her plan to keep Supers illegal forever.

Background
Evelyn's parents were big supporters of the Supers. So, when she and her brother inherited the company, they continued this support and decided to take it to the next level, kicking off a campaign to help the Supers' cause. Since the government shut down the program that helps supers, the time was right for the Deavors to step in.

Brilliant, but laid-back, Evelyn knows her way around tech. She has never met a problem she cannot solve. When Helen is recruited to help the Deavors bring back Supers, she and Evelyn become fast friends. Exchanging ideas, creating strategies, and sharing a lot of laughs along the way. They form a sisterhood, and find they have a lot in common. They are both strong and smart. Evelyn does a cost-benefit analysis and finds that Helen tends to solve crimes with far less damage than Bob, which is why they choose Helen for the job.

Deep down, she hates supers and believes that the world and her family would be better off without them. Which is why she secretly build hypnotonic tech that would allow her to make sure that supers stay illegal, while falsely supporting her brother. Her hatred was triggered by the death of her parents as their support and faith in supers, in Evelyn's eyes, prevented them from defending themselves from the robbers that killed them, when they were waiting for supers to save them.
