An Jack-Jack Parr

**An Jack-Jack Incredible** is .

## Background

### Personality

Jack-Jack acts just like a typical baby. He laughs and giggles a lot but cries whenever he is disturbed. Like many infants, Jack-Jack's emotions are unpredictable; and since his powers are stimulated by them, being with him when the baby uses his powers becomes very difficult when attempting to pacify or restrain him. For instance, Jack-Jack loves Mozart's music to the point where he is stimulated by it. He also becomes enraged if he is given a cookie and is not allowed more. The few things that can calm him down are his family, specifically his mother.
Jack-Jack is smart and intuitive for an infant as he recognized Syndrome as an enemy and identified the exploding plane as a danger. In fact, he was the one who made his father accidentally kill Syndrome. Jack-Jack even recognized that the hypno mask Elastigirl was wearing made her evil, causing him to release her by removing it.

### 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. Although he is usually seen in a yellow onesie during his on-screen appearances in the film, he also has a red super suit with a black mask. When he transforms into a little monster, his skin turns red and gains sharp fangs and claws, that he can use to defend himself and look intimidating. When he transforms into a little monster, his skin turns red and gains sharp fangs and claws, that he can use to defend himself and look intimidating. Mozart's music will trigger him into manifesting his powers, which Edna Mode uses to design a new suit that has sensors and a hand-held monitor, which alerts his family to upcoming use of his powers and allows them to counter them quickly. His powers and abilities are significant enough for his siblings to use him as a third member of a rescue team.

### Powers and abilities

* **Polymorphing:** More than simply shape-shifting, 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.
	+ **Smoke Form:** Jack-Jack can convert his body to smoke, making certain objects able to pass through him.
	+ **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.
	+ **Self-Combustion/Flame-Form:** Jack-Jack can 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 flame retardant foam, however. The Lego Incredibles video game also shows that Jack-Jack can create a beam of intense heat while in his flame form.
	+ **Rubber Form:** Jack-Jack can become soft and pliable with a visible sheen in order to fend off sharp attacks.
	+ **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).
	+ **Mimicry:** Jack-Jack is able to mimic features of other people, such as their noses and hair, as well as mimic objects. This is first shown when he copies the facial features of Edna. It is unknown whether he can completely transform into another person.
	+ **Demon Form:** Jack-Jack is able to transform into a demonic creature, with red skin (purple in the Lego video game), long nails, and sharp teeth. In this form, Jack-Jack has a much greater muscle mass, leading to bolstered strength and maneuverability. He's able to combine his Flame Form with his Demon form which further increases its offensive capabilities.
	+ **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 chubbier all over. He can also change his overall size while remaining the same in physical shape when he shrinks.
* **Molecular Vibration:** He can vibrate at an extremely fast rate, dislodging himself out of the arms of enemies or to shake items off.
* **Teleportation:** He can disappear and mysteriously reappear in another location several feet away.
	+ **Dimensional Travel:** He can cross dimensional barriers (labeled 4 on Edna's monitor) and travel through. He can be heard and can hear others through this dimension.
* **Intangibility:** He can pass through solid objects with no visible injuries. This is usually accompanied by a blue electric effect. Jack-Jack is also able to use this ability to pass through force-fields.
* **Enhanced Bite/Matter Ingestion:** He can chew and eat his way through the bars of a wooden crib.
* **Telekinesis:** He can move objects with his mind.
	+ **Levitation:** He can also lift himself into the air. It is unknown at this time if this power is self-propelled flight or part of his telekinesis, but he can manipulate the direction he wants to go as well as launch himself in the air to a tremendous height with just a sneeze.
* **Laser Vision:** He can fire needle thin green lasers (blue in *Jack-Jack Attack*) from his eyes. These are apparently light-based as they can be reflected easily by a hand mirror.
* **Electrokinesis:** He can generate electricity.
* **Wallcrawling:** He can cling to, climb and sit on ceilings and vertical surfaces. This may or may not be tied to his levitation ability.
* **Self-Duplication:** He can create duplicates of himself.
* **Enhanced Strength/Invulnerability:** He is strong enough to physically fight a raccoon and throw lawn furniture. He does this without physical damage as stated by Bob Parr.
* **Superhuman Speed:** As shown in *Auntie Edna*, Jack-Jack can move at high speeds. However, he doesn't appear to be as fast as his brother, Dash.
