Benjamin "Ben" Kirby Tennyson, self-nicknamed Ben 10,000, is one of Ben's futures, set 20 years from Ben 10: Ultimate Alien's time frame.

Originally connected to the Prime Timeline, this Ben 10,000's future branched off and became an alternate timeline to the present-day 18 year old Ben in the Ominihero time frame.

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 differently; 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 silver boots with green on them. He also has an alternate black and green sleeveless shirt with the Omnitrix symbol on the chest. Like the other Ben 10,000, he has a belt on his waist with pouches for various missions.

Compared to the other Ben 10,000, this one is much more like Ben Prime. For an adult, he is a cocky and laid-back person who tends to make jokes, even when fighting. He easily gets full of himself and enjoys attention.

It remains 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.


As a professional hero, he has been through many adventures. He's been president of Earth, learned magic, and eventually unlocked his greatest transformation: Ultimate Ben. After discovering an Ultimate Form for his conventional human form, Ben 10,000 has had only to partially transform into any of his actual alien forms for years. Despite being still able to transform into aliens, Ben preferred using Ultimate Ben for quicker access to the aliens' powers in combat.

At one point, Ben 10,000 was the President of Earth and defeated the third Vilgaxian invasion during his term in office. His cousin Gwen became president after Ben's term, becoming better at the day-to-day responsibilities the job required than he was, and is "a shoo-in" for a second term.

In Ben 10,000 Returns, Ben 10,000 battled Eon in his headquarters and easily defeated him. He is then approached by Professor Paradox and the two go back in time 20 years.

Powers and Abilities

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.

Ben 10,000 has an above average eidetic memory, as he is able to remember even conversations from years ago with precise clarity.

Ben 10,000 has learned "a few tricks" from Gwen.


Ben 10,000 has unlocked and mastered all the powers of the Ultimatrix. In addition to instant access for as long as he wants (including Ultimate Forms), he can do so with all of their powers while partially transforming into them by instead using his own ultimate form, Ultimate Ben.
