Pixar Wiki

John "Jack-Jack" Jackson Parr (born c. 1961) is one of the supporting characters in The Incredibles and one of the major characters in its sequel. He is the youngest son of Mr. Incredible and Elastigirl and the younger brother of Violet Parr and Dash Parr. Also, he is one of the prominent characters in the short films, Jack-Jack Attack and Auntie Edna. His primary power is shapeshifting - specifically polymorphism - but has also exhibited many other powers.

The Incredibles

"The only normal one is Jack-Jack, and he's not even toilet trained."
Violet Parr complaining to her mother about not being normal

Jack-Jack is a baby and he is 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 Dash Parr. For the first year to year and a half of his life, Jack-Jack didn't seem to exhibit any signs of powers, presumably being too immature for superpowers to manifest.

Jack-Jack is first seen being bathed by his mother, Helen, in a kitchen sink while she talks with his father, Bob, over a telephone, telling him that the family has just moved in. During the scene where the family is having dinner, Jack-Jack is shown to enjoy watching his older siblings Dash and Violet fighting (Dash teases Violet about her crush on her schoolmate, which insults Violet). When a doorbell is rang by family friend Lucius Best (Frozone), which also stops the fight and makes the Parrs return to their seats, Jack-Jack turns to the door and asks "Hello?"

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.

When the rest of his family is occupied with a supervillain named Syndrome, Jack-Jack is looked after by Kari McKeen. But her determination to have some fun ends with trouble when Jack-Jack begins showing signs of his powers that she tries to control and eventually anticipates. Later, Syndrome shows up, and Kari, thinking he is the replacement babysitter, eagerly places Jack-Jack into his care.

When the Incredibles return home, they find Syndrome with Jack-Jack in his hands as he openly declares that he will raise him to become his sidekick. With that, Syndrome kidnaps the baby and flies away to his jet, but 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. As Elastigirl turns herself into a parachute to bring Jack-Jack safe to the ground, Jack-Jack notices an explosion way above her (Mr. Incredible has thrown his car at Syndrome's jet, knocking Syndrome off balance, and Syndrome—wearing a cape—gets pulled into the jet's turbine, leading to his death and the destruction of his jet). Soon after Elastigirl and Jack-Jack lands safely on the ground, the wreckage of Syndrome's jet falls onto the Parrs and their residence, destroying their house, but the family survive thanks to Violet wrapping her force-field around them. Jack-Jack also chuckles to Dash's remarks of the possibility of the family having to move again.

Three months later, Jack-Jack is seen with his family at Dash's track race. After the race, The Underminer emerges from underneath the earth and declares war, and the family, including Jack-Jack, put on their masks.

Jack-Jack Attack

"The baby was exploding! You ever seen an exploding baby before, Mr. Dicker?!"
Kari McKeen to Rick Dicker

Jack-Jack is the titular protagonist in the short film, with Jack-Jack being at home with a babysitter Violet sent for, being Kari, a friend from school.

Rick Dicker interrogates Kari, who has been having trouble trying to control Jack-Jack. Kari decides to stimulate his cognitive abilities by giving him some educational toys and playing Mozart for him (as she has heard that Mozart makes babies smarter). Listening to the music, he has an epiphany about his powers.

Over the course of the night, he demonstrates many different powers, such as floating through the walls, catching on fire, and shooting laser beams out of his eyes, and Kari tries to keep him and the house in one piece. By morning, Kari has been up all night and figured out how to counter his powers. In her frazzled state of mind, she hands him over to Syndrome, whom she believes to be a replacement babysitter contacted by Helen. When with Dicker, 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.

Incredibles 2

"You...have...POWERS! Yeah, baby! And there's not a scratch on you! Did you go right through the locked door? Are those your powers? Haha! You can multiply like rabbits and go right through any... solid..."
Bob Parr, upon discovering that Jack-Jack has powers following the latter's fight with a raccoon

Jack-Jack is confirmed to make a return in Incredibles 2, where he is shown to be the same age as the first film, as it takes place immediately after the Underminer begins attacking the city. He is with the family as they fight the Underminer, but since nobody wants to look after him, they keep trading him off to someone else. He witnesses Violet revealing her secret identity to Tony Rydinger, and is with his family when they are arrested.

Bob doesn't notice that Jack-Jack can teleport when he keeps escaping his crib to watch TV. He shows more of his powers while fighting Rocky, to the awe of his father. He eventually notices Jack-Jack fighting with Rocky but Bob is too exhausted to try to control them. Bob tries to hide his powers from everyone else to prevent Helen from returning home. Eventually, Violet and Dash witness Jack-Jack's powers and they find out Bob is so sleep-deprived from trying to reign in Jack-Jack, so they call Lucius. At first, Lucius sees a normal infant but is surprised when his powers activate and describes Jack-Jack's abilities as "freaky" and advises Bob to get some outside help.

Bob leaves Jack-Jack in care of Edna, who refuses at first, but is ecstatic when she learns Jack-Jack has powers and babysits him for the night to create a supersuit for him. When Bob picks Jack-Jack up, Edna reveals she upgraded Jack-Jack's suit to help Bob handle him and gives a demonstration. During the demo, Edna reveals that listening to Mozart's music caused Jack-Jack to unleash his powers. She tells Bob he should never use cookies as it will trigger Jack-Jack's monster and fire forms. His supersuit follows the sequence of his powers (e.g. if Jack Jack gets mad that he can't have a cookie he turns into a monster, which the suit prepares for; if Jack Jack bursts into flames the suit has an edible flame retardant made of blackberry-lavender.).

After Bob leaves to rescue Helen, the hypnotised wannabe Supers are sent to hypnotize Frozone and the children by Evelyn Deavor. With Frozone hypnotized, the children escape in the Incredibile summoned by Dash and make their way to the Devtech ship to search for their parents. Violet leaves Jack-Jack with Dash as she looks for their parents, but Jack-Jack wanders around the ship, becoming agitated as he has been without his mother for a long time. They eventually find them as well as Frozone but are forced to take cover in Violet's force field as their mind-controlled parents and Lucius attack them. Jack-Jack then floats through the force field to his mother. Noticing the goggles, he uses his telekinesis ability to levitate the goggles off Helen, freeing her from Evelyn's control. Helen then removes the goggles from Bob and Lucius before proudly embracing her children. Jack-Jack uses his powers to assist in freeing the other hypnotized Supers from Evelyn's control. Helen is shocked to learn of them and Bob tells her they have to catch up later. Following Evelyn's arrest, Helen can't believe she missed watching her son's powers as Bob tells her that he has more. Later on, the Supers are made legal again. After his family drops Tony Rydinger off at the movies, he officially joins them in fighting crime.

Auntie Edna

Jack-Jack is the deuteragonist of this short film. Bob takes Jack-Jack to Edna for her to study the powers he uses while Bob caught up on some much-needed rest. Taking Jack-Jack to Edna, she studies different superpowers he uses to impress her. When Edna becomes crowded by multiple Jack-Jack clones, Jack-Jack uses his monster form, combining it with his fire form. Later, Edna examines Jack-Jack for his powers he used and giving him a red suit. After studying, Edna then takes Jack-Jack to Bob as she explains to him that whenever she babysits Jack-Jack (unlike other babies), she does not charge him as Bob and Jack-Jack leave for home. At the end of the short, Edna notices Jack-Jack (presumably a clone of himself) next to her, as Edna runs off telling Bob that he forgot his baby.

Physical Appearance

Jack-Jack is small, albeit at the average size for a baby as he stands at 2'6". He has a single tuft of strawberry-blonde hair on his head and blue eyes. He also has two baby teeth on the bottom of his mouth. Also, he is 1-year-old.

Powers and Abilities

"Your child is a polymorph. Like all babies, he has enormous potential. It is not unknown for Supers to have more than one power when young, but this little one has many."
Edna Mode to Bob Parr about Jack-Jack

Despite being the youngest member of the Parr family, Jack-Jack has displayed the widest array of superhuman abilities. Many of these abilities center around shapeshifting, and he is able to operate multiple abilities simultaneously. Due to his age, he doesn't yet have complete control over his abilities, which are triggered primarily by emotion and whim. Edna Mode classified Jack-Jack as a polymorph, likening his many powers to him being a baby, and thus having limitless potential. When Helen becomes annoyed that she missed Jack-Jack's first display of power, Bob humorously remarks that she missed "the first seventeen".

  • Polymorphing: More than simply shapeshifting, Jack-Jack can manipulate his physical properties to achieve a variety of effects. So far he has displayed the following abilities:
    • Metal Form: Jack-Jack is able to convert his body into heavy metal, giving him a much greater weight and density.
    • Mimicry: Jack-Jack is able to mimic features of other people, such as their noses and hair, as well as mimic objects. It is unknown whether he can completely transform into another person.
    • Monster Form: Jack-Jack is able to transform into a monster-like creature, with red skin, long nails, and sharp teeth. In this form, Jack-Jack has a much greater muscle mass, leading to bolstered strength and maneuverability.
    • Putty Form: Jack-Jack can become soft and pliable with a visible sheen in order to fend off sharp attacks by becoming gooey and/or adhesive.
    • Self-Combustion/Flame-Form: Jack-Jack alter his physiology to set himself aflame and can, to some limited extent, extend the fire around him. As his body remains solid, it seems that it is simply his skin that combusts. His flames can be doused with the retardant foam that Edna Mode programmed into his super suit.
    • Size Manipulation: Jack-Jack can increase his mass and physical size to break through small spaces or crash through walls. While in giant form he is visibly fatter all over. He can also shrink to a small enough size to fit on top of the nipple of a baby bottle. When shrinking he retains his normal physical shape and proportions.
    • Smoke Form: Jack-Jack can convert his body to smoke, making certain objects able to pass through him.
    • Sparkler Form Jack-Jack can convert his body into a mass of sparks while spinning in circles, which gives him a degree of control over electromagnetism (he was able to short out the power all across Edna's estate).
    • Water Form: Jack-Jack can convert his body to water while maintaining his shape, but a simple touch can cause this form to pop like a water-filled balloon.
  • Dimensional Travel: Jack-Jack can cross dimensional barriers and travel through to reappear elsewhere in the room. He can be heard and can hear others while in this other dimension.
  • Electrokinesis: Jack-Jack can generate electricity to some unknown extent (it appears as blue lightning).
  • Laser Vision: Jack-Jack can fire needle-thin green (blue in Jack-Jack Attack) lasers from his eyes. These lasers can be reflected easily any sort of reflective surface, including a hand mirror. The lasers can be maintained, fired rapidly or come closer together, as seen with his fight with the raccoon.
  • Levitation: Jack-Jack can hover several feet into the air. His maximum speed and maneuverability while using this power are unknown; however, he does seem to be able to control his general direction as well as launch himself in the air to a tremendous height with just a sneeze. Whether this power is self-propelled flight or an extension of his telekinetic abilities is unknown.
  • Molecular Vibration: He can vibrate at an extremely fast rate, dislodging himself out of the arms of enemies or cause objects to melt or combust.
    • Phasing: Jack-Jack, most likely by altering his molecular state, is able to phase through solid objects and even his sister's force fields. Doing so is usually accompanied by a blue electric disturbance around the places he enters and exits.
  • Superhuman Strength and Durability: Even as an infant, Jack-Jack is able to lift and throw lawn chairs with little effort and battle a raccoon without taking any damage, indicating that he has superhuman levels of strength and durability.
  • Self-duplication: Jack-Jack is able to create numerous duplicates of himself. Whether or not he is limited to a certain number of duplicates is unknown.
  • Telekinesis: Jack-Jack can levitate, propel and manipulate objects and matter with his mind.
  • Teleportation: Jack-Jack has the ability to teleport to any location. It is unknown how far he is able to travel using this technique.
  • Superhuman Speed: Jack-Jack can move at high speeds. However, he doesn't appear to be as fast as his brother.
  • Wall-crawling: He can cling and sit on ceilings and walls, including other vertical surfaces. This may or may not be tied to his levitation ability.


  • According to official sources, Jack-Jack is 1-year-old, he stands at 2'4" (0.71 m) in height, and he weighs 30 lbs (13 kg).[citation needed]
  • A teaser trailer shows Jack-Jack using his laser vision to cut the "I" in the Mr. Incredible emblem in two, followed by a shot of Bob Parr being overjoyed at the realization of his powers. This implies that this information was not known to the Parr family prior to the sequel, which lines up with the fact that none of them actually witness Jack-Jack using his powers in the first film.
