Jack-Jack Parr is the Parrs’ infant son, the youngest of the Parr children. According to a guidebook published by Dorling Kindersley, his hair never needs hair gel. Initially believed to be the only family member without any powers, he manifests a multitude of superhuman abilities at the end of the film, most of which are types of shapeshifting. 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.
