Jack-Jack Parr

''"The only normal one is Jack-Jack, and he's not even toilet trained." ''-Violet Parr

John "Jack-Jack" Jackson Parr is one of the supporting characters in The Incredibles.

The Incredibles
Jack-Jack is a baby and the youngest child of the Parr family; his parents are Mr. Incredible (Bob Parr) and Elastigirl (Helen Parr), and his older siblings are Violet Parr and Dashiell Robert Parr. His primary power is shapeshifting, but has a large number of other powers.

Jack-Jack uses his powers to defend himself against Syndrome by turning into a fireball, a heavy steel ball, and a small monster. He disables one of Syndrome's rocket boots, causing the supervillain to fly uncontrollably and crash into his jet; upon impact, Syndrome drops the baby. Jack-Jack is rescued by Elastigirl, who is thrown into the air by Mr. Incredible on her command.
