Ben 10: Cosmic Restoration

The year is 2212. Most remaining life in the Milky Way is living on a distant moon, called Droveri12H, following Vilgax's conquering the galaxy. After the creation of thousands of Omnitrix devices, many were sent down to the moon, allowing several civilians to claim them for themselves. Many of these were sentient, including 43 and 42.

Following their arrival, some strange multiversal phenomenon resulted in the appearance of Ben Tennyson, who was believed to have been dead for the past 100 years. An alternate version of a teenage Ben, who had merged with his Omnitrix.

Several Omnitrix users, this version of Ben Tennyson, the Plumbers, and a terrorist organization known as the Storms Eye, all worked together to defend against the many threats plaguing Droveri, including a war sent by a neighboring moon, mutant alien soldiers created by Vilgax, and many other dangers.

After months of struggle, the battle against Vilgax's armies led to the abandoned human home world: Earth. Droveri's heroes fought valiantly, but in the end, they were only able to win the battle thanks to the sacrifice of Ben Tennyson, who became Alien X for the rest of his life in order to ensure the defeat of the universe's dictator.

After Ben turned into Alien X and bested Vilgax, he used all the 1,000,000 alien samples in the Omnitrix (besides Ghostfreak and Big Chill, who had died prior), plus the DNA samples in an Osmosian named Zack, to repopulate the universe, as well as repairing damage to most if not all planets in the universe to make them inhabitable again, including Earth.

Most of our heroes returned to Droveri, where most of them lived their entire life, but that doesn't mean problems don't crop up on Planet Earth. With two planets for both Aliens and Humans, more Heroes need to appear, but with more light, comes more darkness.
