Other Various Bens
|Voice Actor||Sean Donnellan|
|First Appearance||Ben 10,000 Returns|
Ben 10,000 battled Eon in his headquarters and easily defeated him. After he and Professor Paradox went back in time, this Ben 10,000 later reveals to Ben and his team that he is a different Ben 10,000 from the one seen in Ben 10,000 and Ken 10.
Like his parallel counterpart, Ben 10,000 is rather tall and well-muscled with a full beard. While looking like the other adult Ben, he dresses different; his hair is combed over and he wears a white shirt with grey sleeves that forms the hourglass symbol. He also wears green pants and black boots with brown on them. Like the other Ben 10,000, he has a belt on his waist with pouches for various missions.
This Ben 10,000 is much like the current Ben; he's still a cocky and immature person who tends to make jokes even when fighting. He easily gets full of himself and enjoys attention. It's unclear whether this still stems from the fears he still holds about certain situations but he proves to have the gift to make the right choices at the right moments.
Powers and Abilities
Ben 10,000 has unlocked and mastered all the powers of his new Omnitrix (which looks just like the recalibrated Omnitrix). In addition to instant access for as long as he wants (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.
Alien Powers Used So Far As Ultimate Ben
Ben 10: Ultimate Alien
- Ben 10,000 Returns (first appearance)
- According to Derrick J. Wyatt, this Ben 10,000 is no longer Ben's future.
- According to Matt Wayne, this Ben 10,000 started calling himself Ben 10,000 after the Plutonian revolt of 2022.
- According to Eon, this Ben is unlike the others he encountered.
- Ben 10,000 can still do the actual alien transformation, but he just prefers to use Ultimate Ben for quicker access in combat.
- At one point, Ben 10,000 was president and defeated the third Vilgaxian invasion during his term in office.
- Ben 10,000 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).
