The Nemetrix is a knock-off version of the Prototype Omnitrix that Khyber  uses to turn his dog into the predatory species of the Omnitrix Aliens.

General Information

Khyber's Pet

Phil (Formerly)

Type DNA Alterer
First Appearance The More Things Change: Part 1

A Cerebrocrustacean named Dr. Psychobos  and a Galvanic Mechamorph named Malware  invented the Nemetrix for Khyber in order to retrieve Ben's Omnitrix. It's real purpose was to destroy Azmuth and with the Nemetrix now perfected the Omnitrix is no longer needed.


The Nemetrix is shaped like a hexagon. It is colored red and silver. The symbol looks like a jaw with sharp teeth.

Powers and Abilities

The Nemetrix has the ability to transform like the Omnitrix but instead, it transforms the user (Khyber's Pet) into non-sapient alien beings that are actually the predators of Bn's aliens. Khyber's Pet can transform with the instructions given by Khyber via his whistles.

Later Dr. Psychobos tried to upgrade the Nemetrix so that Khyber's Dog can transform without Khyber whistling but failed. So Dr. Psychobos upgraded the Nemetrix with the stolen Omnitrix stabilizer core as seen in Outbreak, so now Khyber's Dog is now able to transform free at will, as seen in Malefactor.



  • It was originally named Predatrix but later renamed.
  • Nemetrix name comes from the word "nemesis", which is another word for villain or foe.
  • The aliens whose DNA the Nemetrix contains are not considered sentient, which is why they are not in the Codon Stream.
  • According to Derrick J. Wyatt, the aliens in the Nemetrix are feral beasts while Ben's aliens are roughly the equivalent of humans or more "advanced" beings.
  • According to Derrick J. Wyatt, Khyber had the Nemetrix for about five years.
  • When a transformation is made through the Nemetrix, the sound is similar to the Omnitrix  from the Original series. Most likely because the partial design to make it was the original Omnitrix.
  • Similar to the Omnitrix symbol being seen on every one of Ben's transformations, Khyber's dog's collar with the Nemetrix on it can be seen on every Nemetrix transformation.
  • According to Derrick J. Wyatt, only a non-sentient being can wield the Nemetrix
    • Though Phil (being sentient) had used it but with dangerous side effects as said by Khyber, sentient lifeforms could not handle the savage feral nature of the Nemetrix aliens.
  • Derrick confirmed that there will be toys of Nemetrix aliens.
