Juryrigg is the Omnitrix's DNA sample of a Planchaküle from the planet of Aul-Turrhen.
Juryrigg is a small, red, devil-like alien who bears a close resemblance to a Gremlin/imp. He is very small, as when he was next to Gwen he was almost as big as her head, excluding the tail. He also seems to be a little taller than Grey Matter, but smaller than Upchuck. He wears the Ultimatrix symbol on his chest.
In Omniverse, Juryrigg now wears an aviator's outfit which comes with an ascot. He looks more red. He now has pupils. His ears are now spiked and his nose is bigger. He also has a spike on his chin and one near each of his eyes. The Omnitrix symbol is now on his waist.
Juryrigg has a strong desire to break and remake machines, making him difficult to control.
Juryrigg has a mischievous (and twisted) sense of humor, such as turning Will Harangue into an alien as payback for all the smear campaigns and crimes he committed against Ben and other aliens.
As shown in several episodes in Omniverse, Juryrigg says, "Juryrigg disassemble!", "FIX FIX FIX FIX FIX!" and "Reassemble, disassemble!"
Powers and Abilities
Juryrigg has the ability to completely disassemble any kind of machinery in mere seconds, fitting to his Gremlin appearance. Despite it being harder for him to do due to his craving to destroy things, Juryrigg can also construct complex machinery from scratch at a similar rate.
Juryrigg has a form of enhanced strength for his size, able to break a metal car brake in half. He has shown to be strong enough to break apart metal bars that even an Appoplexian could not break.
Juryrigg has a degree of enhanced agility.
As in accordance with his break it/fix it attributes, Juryrigg also boasts an impressive intellect, describing himself as "smart and stubborn".
Being small makes Juryrigg unsuitable for hand-to-hand combat against larger opponents, unless they happen to be machines. In which case, he can dismantle them in seconds.
Juryrigg has a near uncontrollable habit of breaking machinery and assembling machines.
Like his name, most of the devices Juryrigg creates are basically on-the-fly or 'jury-rigged.' They are not normally meant to last, (except for the Tenn-Speed) and will eventually fail. Juryrigg's creations can be unstable and hard to control, much like Juryrigg himself.
