History
Gwendolyn's Omnitrix was created by a android named Galatrix, About 25,000 Earth years ago with the desire to study, preserve and collect all the DNA in the galaxy. Her intentions for the device was to help bring peace to the universe, by allowing each species to "walk a mile in each other's shoes" in order to bring about universal understanding. Not to mention have a way of bringing back any intelligent species going, or gone extinct.

The Omnitrix was for the most part been kept top secret from everyone besides Galatrix herself, as she kept working on the device for thousands of years in her private dimension, the Dark Zone. However, it was inevitable that the device would be rumored to exist when Galatrix first made contact with the Plumbers in order to secure someone to both handle and protect the device, thus individuals like Vilgax, Dragollia and many more sought the power of the Omnitrix to only further their own goals.

At some point during Earth year 2022, the device crashed landed on Earth and was discovered by Dragollia. Although, even though Dragollia now had the device it refused to lock unto any of her lackeys or even herself due to it being DNA locked. fortunately it didn't take long before the dragon mistress found the individual with matching DNA, Gwendolyn Tennyson.

As Gwendolyn's DNA match that to Maxwell Tennyson, her grandfather and the greatest Plumber in 5 galaxies.
