Forearm-mounted device in Ben 10 that transforms its wearer into various aliens.
In the Classic series, the Omnitrix was a prototype made by Azmuth. It then upgraded itself into a new design during Alien Force. Its true purpose is to be an extensive catalogue of all Alien DNA samples should any galactic event cause the extinction of every living species.
If an image solely features the hourglass-like symbol featured on the Omnitrix, use the Omnitrix symbol tag instead.
