The Omnitrix is a device that allows its wearer to transform into 55 million different aliens. Both of the Omnitrixes were created by Azmuth.

Azmuth wanted to create the Omnitrix so he could understand and communicate with other aliens around the galaxy. When Azmuth was finished with the Omnitrix, his home planet, Galvan Prime was attacked multiple times by Vilgax because he wanted the Omnitrix. After Vilgax failed every time to retrieve the Omnitrix, he stopped trying. Azmuth then decided to send the Omnitrix to Earth because he thought that it would be better if a very well trained Plumber used it. The Omnitrix did not arrive at the Plumber base because the ship malfunctioned and crashed near an area where Ben was. Ben went to the crash site and went inside the ship because he was curious, he saw the Omnitrix in the ship and when he went near the Omnitrix it jumped on Ben's wrist and he couldn't take it off. He then started to mess around with the Omnitrix and accidentally transformed into an Alien. After he transformed, he went to Plumber base to tell them what happened and the Plumbers told him what the Omnitrix was. After he knew what it was, he wanted to use the Omnitrix to help and save people.
Gwen's Omnitrix was created after Azmuth met Gwen.
