Already very powerful for a baby
Jack-Jack is the newest member of the Parr family in the Incredibles movie and its sequel Incredibles 2 from Disney Pixar Studios. Although the movie comes out fourteen years after the first one, it takes place right after the first one, so the kids are still the same age. The Parr family has been living in anonymity since superheroes became illegal after an accident with a supervillain. But a new villain named Screenslaver comes to town and causes chaos and the Parr family has to get back to work. Jack-Jack has the power to manipulate molecules. This means that he can transform himself into anything he wants, but he can also teleport or create duplicates of himself.
