|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.
Ben 10,000 dresses different than his counterpart; his hair is combed over and neat, he sports a beard. He wears a white shirt with grey sleeves that forms the hourglass symbol. He is less muscular than his counterpart. He wears green pants and black boots with brown on them. Like the original 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, arrogant 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 assilants 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.
