While Dash and Violet will continue with the crime-fighting ways, reports indicate that their youngest brother Jack-Jack will be a focal point in the story.
Unfortunately, unlike his superhero parents and his sister and brother, Jack-Jack cannot control his powers. His parents have also become very protective of him following Jack-Jack’s kidnapping by a villain. Eventually, Jack-Jack became an outcast and a rebel.
It was during this time that Jack-Jack realized that he can only control his super power abilities if he is angry or becomes villainous. Unfortunately, it was another villain, which speculations say is to be known as Syndrome, who first saw these unique traits of Jack-Jack and he thus mentored him to become a great villain under his tutelage.
