Ben 10,000 (Ultimate Alien)

'This article is for the real future Ben Tennyson. You may have been looking for the cross-time version from the original series.'

Ben Tennyson, nicknamed "Ben 10,000", is Ben, twenty years from Ultimate Alien's timeframe.

Ben 10,000 battled Eon in his headquarters and easily defeated him. Paradox reveals this is a different Ben 10,000 than the one seen in Ben 10,000 and Ken 10 and is Ben's older-self and thus from the same timeline as Alien Force and Ultimate Alien.

Powers and Abilities
Ben 10,000 has unlocked and mastered all the powers of his Ultimatrix; which looks just like the recalibrated Omnitrix. In addition to instant access for as long as wanted (including Ultimate Forms), he can do so with all of their powers without transforming into them by instead using his ultimate form, Ultimate Ben.

Ben 10,000 is incredibly skilled in hand-to-hand combat, able to easily fend off several skilled assailants with no aid from his powers. He has an above average eidetic memory, as he is able to remember even conversations from years ago with precise clarity. He has also learned "a few tricks" (referring to spells) from Gwen.

Trivia

 * Ben 10,000 is taller than what he should be. He's shown to be much taller than his father and grandfather, but his alternate counterpart is at a more accurate height (slightly taller than Max and Carl).
 * Ben will start calling himself Ben 10,000 during the Plutonian revolt of 2022.
 * Unlike the other Ben 10,000, this Ben 10,000 switches back to his human form after the battle is over.
 * When it comes to which form Ben 10,000 chooses, this Ben 10,000 is the exact opposite of the first Ben 10,000 from "Ben 10,000." Ben 10,000 from that timeline was hardly ever in his human form, preferring to stay in alien form, until young Ben convinced him to change his ways. This Ben 10,000, having discovered Ultimate Ben, allowing him to use the abilities of all his other forms in one, remained in his Ultimate form and would choose which alien's abilities to use, rather than turning into them.
 * Ben 10,000 can still do the actual alien transformation, but he just prefers to use his Ultimate Ben for quicker access.
 * Ben 10,000 stated that he enjoyed annoying Azmuth when he restored Ben's lost alien forms, by adding a few new aliens that Ben hasn't unlocked yet after restoring both versions of Swampfire, Way Big, and reunlocking all the other original series aliens.
 * It is also implied that Ben 10,000 could've completely unlocked the Master Control for Ben but refuses when asked to stating that it would get him in more trouble with Azmuth, implying that he has done several things over the past 20 years that angered Azmuth.
 * At one point, Ben 10,000 was president and defeated an alien invasion during his term in office. He says Gwen became president after his term (even admits Gwen was better at the day-to-day responsibilities the job required than he was and said she's a shoe-in for a second term).
