Ben 10,000 is the fully grown "future" version of the main timeline Ben Tennyson, who has become a full-time superhero. He appears throughout the shows in some time-travel episodes. There are two versions of him, one who was used in the original series and one who was used in Ultimate Alien. Both are equally canon as the many possible alternate futures of Ben. However, as of Omniverse, the original Ben 10,000 is stated to belong to the main timeline.
