The Incredibles Disney Pixar Big Baby Jack Action Figure....in original box and never opened........John Jackson "Jack-Jack" Parr (Eli Fucile and Maeve Andrews in the first film, Fucile and Nicholas Bird in the second film) is the Parrs' infant son, the youngest of the Parr children. Initially believed to be the only family member without any powers and shown as a minor character (as he did not join the family in the first film), he manifests a multitude of superhuman abilities at the end of the first film, most of which are types of shapeshifting, when Syndrome tries to kidnap him. More powers are seen in the short film Jack-Jack Attack on the Incredibles DVD, making his powers the most versatile of the family, and according to a collectible poster included with some Incredibles toys, still more powers are undisclosed.
