The youngest of the Parr children, Jack-Jack may only be an infant, but he's far and away the strongest and most powerful superhero of "The Incredibles" universe. Originally, the Parrs believed Jack-Jack to be the only non-superpowered member of the family, but in the second half of the original movie and its later sequel (as well as the hilarious short "Jack-Jack Attack"), the full range of Jack-Jack's many, many superhuman abilities are made abundantly clear.
Among Jack-Jack's numerous powers, he possesses superhuman strength, durability, teleportation, levitation, electrical generation and manipulation, and telekinesis, along with the ability to shape-shift (usually into a muscular, red, bestial creature when angered) and create multiple duplicate versions of himself. According to Mr. Incredible, Jack-Jack demonstrates a total of 18 superpowers throughout "The Incredibles 2," although it's hinted that he may actually have far more.
With such a wide array of superpowers at his disposal, Jack-Jack is easily the strongest character in "The Incredibles" series. However, as he is only a baby, he has very little awareness over how to use his powers or the consequences of his actions, usually acting on childish impulses, such as wanting his mother or eating endless amounts of "num-num" cookies.
