Juryrigg

Jury Rigg is the Omnitrix's DNA sample of Planchakule from an unknown planet.

Appearance
Jury Rigg is a small, red, devil-like alien who also bares a close resemblance to a Gremlin/imp. He wears the Ultimatrix symbol on his chest. He is very small, 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.

In Omniverse, Jury Rigg now wears an aviator's outfit. His ears are now spiked and his nose is bigger. The Omnitrix symbol is now on his waist. He also now has pupils.

Powers and Abilities
Jury Rigg has the ability to disassemble or reassemble any machinery at a fast rate. He is pretty strong for his size, strong enough to break a metal brake in half. Jury Rigg is also very agile.

Weaknesses
Jury Rigg has a strong desire to break machines; in other words, he is hard to control.

Trivia

 * Jury Rigg always says what he is doing repeatedly, when breaking something he says "break" and when fixing something he says "fix" over and over again.
 * Jury Rigg is one of Ben's alien forms who is not in the lineup of aliens in the Ultimate Alien intro, the others being Fasttrack, Eatle, Ultimate Wildmutt, Clockwork, Shocksquatch, ChamAlien and Ultimate Way Big although this is due to their existence not being known until just recently.
 * Jury Rigg's tail and the aviator outfit he wears in Omniverse somewhat resembles Terrible Dactyl from Dinosaucers.
 * His powers of fast building are very similar to the Imps from the Aladdin Series, who have the power to construct things at a very fast rate.  Also, Jury Rigg's appearance is similar to that of an imp.
