Miguel Tennyson, nicknamed "Miguel 10,000" is the fully grown Miguel, from an alternate timeline.
Miguel 10,000 has become a full-time hero. He is tall, more muscular, and sports a full-beard. The Omnitrix has also changed in appearance, becoming bulkier and more gauntlet-like in shape. He no longer needs to conceal his identity and is recognized everywhere as Miguel 10,000, no matter what alien form he is using (because his aliens have an Omnitrix symbol).
His nickname comes from the fact that now Miguel has access to at least 10,000 alien forms (he says he stopped counting), he also has unlocked the Omnitrix's Master Control, allowing him to switch forms at will, without timing out.
Having been fighting crime for such a long time, Miguel 10,000 has grown into a strict and serious character, stopping naming his aliens (which the present Miguel considers "half the fun" of using them), and has a darker way of dealing with villains, such as defeating Kevin by literally mutilating him (according to a pop-up, this happened when Miguel 10,000 was 15), though his interaction with his younger self causes him to lighten up somewhat, renaming his aliens. Miguel'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.
It was shown that Miguel 10,000 has a son named Ben (after Miguel's cousin Ben) and a daughter named Gaelletia(after Gaelle). On Ben's tenth birthday he gives him an Omnitrix like the one he had in the original series (like his first one, only he has 10 accessible aliens and has the Master Control locked. The aliens he gave Ben were Upchuck, Shocksquatch, Terraspin, Echo Echo, Squidstructor, Angelhands, Handpick, Turbine, Sandman and Tuskosaur. However, Handpick was later exchanged for Magnet Matter because Benny said that Handpick grosses him out.
