Jack-Jack Parr

**John "Jack-Jack" Jackson Parr** is the youngest son of Bob and Helen Parr, as well as the younger brother of Violet and Dash. His primary power is shape-shifting, but he also has a large number of other powers. He is one of the two tetartagonists (alongside Frozone) of *The Incredibles*, the titular deuteragonist of its first short video *Jack-Jack Attack*, the tetartagonist of *Incredibles 2*, and the deuteragonist of *Auntie Edna*.

## Powers and Abilities

Despite being the youngest member of the family, Jack-Jack has the widest array of superhuman abilities, most of which are centered around shapeshifting. Edna Mode classified Jack-Jack as a polymorph, likening his many powers to him being a baby and thus having limitless potential. Being a baby, he doesn't yet have complete control over his abilities; they are primarily activated by emotion and whim. It is unknown whether Jack Jack will outgrow most or some of his powers, as this is considered normal with infant Supers. The only other Super known to have maintained a host of powers post-infancy is Meta Man.

* **Polymorphing:** More than simply shape-shifting, Jack-Jack can manipulate his physical properties and molecular makeup so as to achieve a multitude of effects. So far he has displayed the following abilities:
* **Mimicry:** He can mimic features of other people such as noses and hair. It is unknown whether he can completely transform to 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 manoeuvrability.
* **Self-Combustion/Flame-Form:** Jack-Jack alters 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 easily doused with flame-retardant foam.
* **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.
* **Smoke Form:** Jack-Jack can turn his body gaseous.
* **Metal Form:** Jack-Jack is able to convert his body into heavy metal, giving him a much greater mass and density.
* **Rubber Form:** Jack-Jack can become soft and pliable with a visible sheen in order to fend off sharp attacks.
* **Water Form:** He can liquefy his body and become liquid.
* **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).
* **Intangibility:** 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 place he phases through. It does seem, however, that he cannot phase through organic substances, seeing as how several people have made physical contact with him while he was phasing through a solid object.
* **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.
* **Superhuman Strength and Durability:** Even as an infant, Jack-Jack is able to lift and throw lawn chairs with little effort and battled a raccoon without taking any visible damage. This indicates that he has some superhuman level of strength and durability.
* **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.
* **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.
* **Teleportation:** Jack-Jack has the ability to teleport. It is unknown how far he is able to travel using this technique.
* **Dimensional Travel:** Jack-Jack can cross dimensional barriers and travel through to reappear elsewhere in a small radius. He can be heard and hear others while in this other-dimension.
* **Enhanced Bite/Matter Ingestion:** He can chew and eat his way through hard, solid objects such as the bars of a wooden crib.
* **Laser Vision:** Jack-Jack can fire needle-thin green (blue in *Jack-Jack Attack*) heat-lasers from his eyes. These lasers can be reflected easily any sort of reflective surface, including a common hand mirror. He is trained to a certain extent, and can be used as a gun.
* **Electrokinesis:** Jack-Jack can generate electricity to some unknown extent.
* **Telekinesis:** Jack-Jack can move relatively small objects with his mind.
* **Levitation:** Jack-Jack can hover several feet into the air. His maximum speed and manoeuvrability while using this power are unknown; however, he does seem to be able to control his general direction as well as launch himself into 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.
* **Superhuman** **Speed:** He is able to move much faster than a normal baby.

## Weaknesses

**Power Instability & Emotions:** Since Jack-Jack is still a baby, he doesn't yet have complete control over his abilities, which are triggered primarily by emotion and whim. Jack Jack does not like being doused when he is in his fire form, picked up when he is in his mimic form or when he is teleporting because he can get himself caught by enemies.
