Ben 10,000 (Ultimate Alien)

If you were searching for the original Ben 10,000, see; Ben 10,000

Ben Tennyson, nicknamed "Ben 10,000," is the fully grown Ben, twenty years into the future. He battled Eon in his headquarters and easily defeated him. Professor Paradox reveals this is a different Ben 10,000 than the one seen in Ben 10,000 (episode), and Ken 10, and is Ben's older-self and thus from the same timeline as "Alien Force" & "Ultimate Alien"

Powers and Abilities
Ben 10,000 has unlocked and mastered all the powers of his Ultimatrix; which appears similar to the recalibrated Omnitrix from "Alien Force". 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 evolved human form, Ultimate Ben, however, doing this requires him to twist the Ultimatrix's face to access his aliens' powers instead of by thought command, this time, by voice.

He is also incredibly skilled in hand-to-hand combat, able to easily fend off several skilled assailants with no aid from his powers. He has a perfect photographic memory, able to remember even conversations from years ago with precise clarity. He has also learned "a few tricks" (referring to spells) from Gwen. It's possible that he also has the full capabilities of an anodite like Gwen.

Trivia

 * When it comes to which form Ben 10,000 chooses, this version of Ben 10,000 is the exact opposite of the first Ben 10,000 from "Ben 10,000." The Ben from that timeline was hardly ever in his own human form, perferring to stay in alien form, until past Ben convinced him to change his ways. This future Ben, having discovered his personal ultimate form, allowing him to use the abilities of all his other forms in one, remained in his Ultimate Ben form, and would choose which alien's abilities to use, rather then 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.
 * Both versions of Ben 10,000 have facial hair.
 * When Ben 10,000 turns into Ultimate Humungousaur he didn't turn into Humungousaur and then slap the Omnitrix to turn Ultimate just like Ben would go Ultimate.
 * No matter what form Ben 10,000 takes, the evolved Ultimatrix symbol always appears, due to him being Ultimate Ben.
 * He also tells 16 year old Ben that he remembers visiting the other Ben 10,000 when they were 10 and even calls him "What a buzzkill".
 * Ben 10,000 even stated that he enjoyed annoying Azmuth when he restored Ben's lost alien forms, by adding a few new aliens that 16 year old 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 16 year old 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.
 * He mentions that he "learned a few tricks from being around an Anodite for 20 years," implying that Gwen taught him some magic.
 * At one point in the future, Ben 10,000 was president, and defeated an alien invasion during his term in office. He says Gwen became president after his term (he 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).
 * As Gwen became president of Earth she would technically be Ben 10,000's successor since he was president before her.
 * This version of Ben 10,000 has found a way to unlock "Ultimate Ben". This is the reason why he does not technically change from his human form whenever he chooses a transformation.
 * The version of Heatblast used by this Ben 10,000 does not have flames spurting from his shoulders unlike the previous Ben 10,000's (though it only appeared as a hologram).
 * Both versions of Ben 10,000 have used Articguana, XLR8, Diamondhead, and Heatblast.
 * Concidentally, Ben 10,000's voice actor, John DiMaggio, also voices Aquaman from Batman: the Brave and the Bold, who has a similar build, goatee, and rather cocky attitude.
 * This version of Ben 10,000 doesn't appear to be as muscular as the other.
