For the first year of his life, Jack-Jack didn't seem to exhibit any signs of powers, presumably being too immature for superpowers to manifest.
When the rest of his family was occupied with Syndrome, Jack-Jack was looked after by Kari McKeen. But her determination to have some fun ended with trouble when Jack-Jack began showing signs of his powers which she tries to control and eventually anticipates. Later, Syndrome shows up, claiming he's the replacement baby sitter. When Syndrome attempts to openly kidnap Jack-Jack and fly away, Jack-Jack uses his powers to defend himself against Syndrome, ultimately resulting in a chain reaction of events that would lead to Syndrome's demise.
Edna Mode made costumes for the entire family, including a flame-retardant jumper for Jack-Jack which, coincidentally enough, is needed as Jack-Jack has the ability to burst into flames and become bulletproof, though this being done before the family could determine the full extent of Jack-Jack's powers. Edna will presumably modify the costume to accommodate all of Jack-Jack's abilities.
In the DVD short, Jack-Jack is now the titular protagonist.
Later on, she says she wishes she could just forget the whole thing, and Dicker reassures her that she will, and uses a device to erase her memory.
Powers and Abilities
Despite being the youngest member of the family Jack-Jack is potentially the most powerful and has the widest array of abilities.
Molecular manipulation: More than simply shape shifting, Jack-Jack can control his molecular make up entirely allowing him to turn into non organic elements, Such as making himself into a living heavy metal or bursting into flames, or allowing his molecules to pass through solid objects as if they were not there. It is unknown if he can effect more than just himself with this ability.
Levitation: Jack-Jack can lift himself into the air with him mind. It is unknown at this time if this power is self propeled flight or if he is telekinetic.
Laser Vision: He can fire needle thin purple lasers from his eyes. These don't seem that powerful as they can be reflected easily by a hand mirror.
