Ever since director Brad Bird let slip that he would be working on the second installment of "The Incredibles" after he finished with "Tomorrowland," fans have been eagerly awaiting news about the progress regarding Pixar's hit movie. Now that the science-fiction mystery adventure film is done, a lot of speculations about plots and characters have been making the rounds in the web.

Crossmap reports that the villain Syndrome will return to cause trouble to the superhero family. He will purportedly use the youngest of the Parr, Jack-jack, against his own family. In the last movie, the baby showed his powers by thwarting Syndrome's plans to steal him when he transformed into a little monster. 

Jack-jack and his powers is said to be the focus of the upcoming sequel. According to Wikia, he will be a six-year-old rebel who cannot seem to control his special abilities. He will soon discover that the key lies in whenever he becomes angry and villainous. Syndrome will allegedly use Jack-jack's confusion and turn him into a sort of apprentice. Then, he will set loose the monster to fight against his own family.

Bob and Helen will be retired from being superheroes. It is now the dynamic tandem of Dash and Violet whom people rely on to fight crimes around the world. Their parents still help them nab bad guys from time to time, but their main focus is now taking care of Jack-jack, who was almost kidnapped five years ago.

Meanwhile, Movie News Guide reports that Samuel L. Jackson's character "Lucius Best aka Frozone" will be seen again in "The Incredibles 2." It also reveals that the plot will be set 11 years in the future instead of just five, as what the other sources claim.

"Every time I run into Brad, he always tells me Frozone is part of what's going on in the sequel, so I have to believe that. I guess they could be the Incredibles without Frozone, but I think Frozone would be a wonderful addition to what's already there," he said.

Pixar has not yet commented on the possible release dates of "The Incredibles 2," but most of the conjectures point to a 2017 or 2018 premiere.
