Omnitrix

The Omnimatrix, referred to as the Omnitrix, is one of Azmuth's creations and the successor of the Ultimatrix. It is the main aspect of the Ben 10 franchise.

The Omnitrix was first mentioned by Azmuth in Map of Infinity. He was planning on giving it to Ben, but it was not complete, and Ben's maturity needed 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 ago). 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.

Appearance
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.
