The Omnimatrix (often referred to as the Omnitrix) is one of Azmuth's creations and the successor of the inferior Ultimatrix.
The Omnitrix was first mentioned by Azmuth in Map of Infinity. He was planning on giving it to Ben, but it was not yet complete, and Ben's maturity needing to increase before he would be allowed to use it.
Azmuth, by the events of The Ultimate Enemy: Part 2, had completed the Omnitrix and claimed that he was working on it ever since Ben got the original Omnitrix (approximately six years). In the same episode, he gave it to Ben because he deemed him worthy of wielding it after removing the Ultimatrix from the latter's wrist.
The Omnitrix resembles a wrist watch. Its face plate is now square instead of round and has a white and green color scheme. The faceplate is black with two green stripes forming an outline for the hourglass of the intergalactic peace symbol. When the faceplate is slid back, the Omnitrix's core is revealed.
The Omnitrix has a holographic interface, where a holographic circle is shown, with the top half having alien faces, which is activated and scrolls through the aliens by the user touching the faceplate, akin to a touch screen. The faceplate will then slide open when the side button is pressed to lock in the selection, the Omnitrix core will come out and when pressed will trigger a transformation.
The Omnitrix has a 2-way communication system with Plumber Badges.
It can also record messages much like voicemail.The Omnitrix when it is activated
The Omnitrix has a distress signal function and homing device as Azmuth was able to find and rescue Ben when was trapped inside the Incursean Exile Pod.
In Arrested Development, it is revealed that the Omnitrix has a security lock system so that only Ben can use it.
It also has an alternate identification program if some change by outside forces occurs to Ben.
The Omnitrix has a randomizer function. This has two modes:
Ben continuously changes between different aliens every few minutes before timing out.
Ben will turn into one random alien for an inconsistent short period of time before changing back.
The Omnitrix has Voice Command:

Active Mode is the Omnitrix's default mode. Normally Active Mode is active when the Omnitrix can be used and nothing is wrong.
Recharge Mode's main purpose is to keep the Omnitrix from damaging the user. Recharge Mode is activated when the Omnitrix runs out of time. Recharge Mode is deactivated automatically, once a certain period of time has passed.
The Omnitrix can scan DNA but it is unknown how it does it.
The Omnitrix randomly transforms the user into different aliens, each for a short time.
The Omnitrix allows Ben to stay in an alien form for an extended period of time without a time-out.
These are aliens that have been named and confirmed to exist. They were never shown to be unlocked or transformed into in Ultimate Alien and have yet to be seen in Omniverse.
