Ben 10,000 (Original)

Ben 10,000 is Ben Tennyson's alias after twenty years of being a superhero who appeared in the episodes Ben 10,000 and Ken 10 one of the possible (as in noncanon) futures was explored. These are timelines possible if Ben had not destroyed the Omnitrix in The Final Battle: Part 2.

Twenty years into the future, Ben has become a full-time hero. He no longer needs to conceal his identity and is recognized everywhere as Ben 10,000, no matter what alien form he is using. The name comes from the fact that now Ben has access to 10,000 alien forms, he also has unlocked the Omnitrix's master control function, allowing him to switch forms at will, without timing out.

Having been fighting crime for such a long time, Ben has grown into a more strict and serious character, going so far as to stop naming his aliens (which the present Ben considers "half the fun" of using them), and has a darker way of dealing with villains, such as defeating Vilgax by literally dismembering him, though his interaction with his past self in the episode Ben 10,000 causes him to lighten up somewhat, naming his aliens all over again. Ben's alien forms have aged with him, which is evident in their appearances and abilities. For example, Ben 10,000's XLR8 is noticeably taller with gray outlines in place of the ordinary blue, as well as being considerably faster.

In the episode Ken 10, it was shown that Ben has a son with possibly Kai Green named Kenneth Tennyson (possibly named after Ben's cousin Ken). On his tenth birthday he gives him an Omnitrix like the one he had in the original series (like his one, he has only 10 accessible aliens and times out). The aliens Ben gave were Spitter, Buzzshock, Shellhead, Ditto, Wildvine, Stinkfly, Toepick, XLR8 and more. It was also revealed he has a daughter named Gwen (probably after his cousin Gwen Tennyson), which could be the girl present at Kenny's birthday party.

Trivia

 * With the look of the Omnitrix, it seems to have not been taken out off Ben's wrist or recalibrated, and it looks like it instead grew bigger while Ben is aging aswell, eventhough he took off sometime before he was 16. And the fact that he is still wearing the Omnitrix and not the Ultimatrix makes this character seem non-canon.
