This timeline follows the Ultimate Alien timeline, ignoring retcons and changes made in Omniverse.
Ben didn't get the Omniverse Omnitrix. Instead, he kept the Ultimatrix.
Ben is destined to become Ben 10,000 and discover his self-proclaimed best transformation, Ultimate Ben, and will stop using his other transformations.
The Plutonians will invade Earth in the year 2022, following which Ben will become the President of Earth before being replaced by Gwen.
