Benjamin "Ben" Kirby Tennyson, self-nicknamed Ben 10,000, was one of Ben Tennyson's futures, set 20 years from Ultimate Alien's time frame.[note 1]
Appearance
Ben 10,000 was rather tall, had a thick and muscular build due to the various adventures he had experienced that had left him in shape,[DR 1] and sports a full beard. His hair was combed left-sided, and he wore a customized skintight outfit: consisting of a dark graphite round-neck T-shirt with a custom white hourglass design in the middle. The shirt was tucked in his green pants pulled up to his waist; a belt with multiple pouches, and black calf-high boots with brown straps on them.
Personality
Compared to the Ben 10,000 from the Original Series, this one was much more like Ben Prime. He was cocky and laid-back for an adult, and tended to make jokes, even when fighting. He easily got full of himself and enjoys attention. However, when the situation called for it, he showed a more serious side of himself.
History
Background
As a professional hero, Ben has had many more adventures than his 16-year-old self. During this period, he gained more powers to show for his reputation and learned how to use some magic in his human form from his cousin Gwen.
Ben eventually unlocked his greatest transformation: an Ultimate form for his human form known as Ultimate Ben. After discovering this transformation, Ben 10,000 has not needed to physically transform into any of his actual alien forms for years. Though he could still turn into regular and Ultimate aliens, he 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. He was eventually succeeded by Gwen.
Ultimate Alien
Ben 10,000 appeared in Ben 10,000 Returns, where he battled Eon and his minions in his headquarters. He easily defeated the minions as Ultimate Ben, but when Eon himself attempted to blast him with a time ray, Ultimate Ben countered using Clockwork's powers and knocked him to the past of his timeline.
Approached by Professor Paradox, Ben 10,000 realized his mistake he had made. Paradox confirmed his fears, and they arrived in the past shortly after present-day Gwen used a spell on the Hands of Armageddon. As Ben 10,000 introduced himself, present-day Kevin mistook him for a different Ben 10,000, before he was corrected. The quintet took the Hands of Armageddon in the Rustbucket 3 as they flew out to a desert, and it summoned more of Eon's minions, which Ben 10,000 once more fought against. Using Jetray's abilities, he helped the Rustbucket 3 make an emergency landing. Using Clockwork and Way Big respectively, Ben 10,000 and Ben tried to destroy the Hands of Armageddon, in turn accidentally summoning Eon to the present.
Confronted by Eon and his minions once more, Ben 10,000 took on the latter before saving his past self from the latter. After Eon revealed himself to be an alternate version of Ben, Ben 10,000 helped Gwen and Kevin fend him off while Ben as Jetray destroyed the Hands of Armageddon. Upon its destruction, and Eon's defeat, Ben 10,000 restored his past self's transformations, in addition to adding new ones. He was soon returned to his future by Paradox.
At some point between Ben 10,000 Returns and Ben Again, Ben 10,000's timeline was erased.[DJW 1][DJW 2]
Powers and Abilities
Ben 10,000 was incredibly skilled in hand-to-hand combat and martial arts, able to easily fend off several of Eon's minions with no aid from his powers.
Ben 10,000 had enhanced reflexes, as shown when he narrowly dodged being hit by Eon's time ray.
Ben 10,000 had an enhanced eidetic memory, as he was able to remember even conversations from years ago with precise clarity.
Ben 10,000 had learned "a few tricks" from Gwen, as shown when he, in his Ultimate Ben form, cast the Contego spell which created a magic wall made of manna to protect himself from Eon's temporal energy blast.
Ben 10,000 seemed to have a good understanding of the Ultimatrix, as he was able to restore Way Big, Swampfire and Ultimate Swampfire after they were destroyed, while unlocking several new aliens his teen self did not yet have access to. He also knew the Master Control code, though he refused to give it to his younger self, since he claimed that he was already in enough trouble with Azmuth.
Equipment

Ultimatrix
Ben 10,000 had unlocked and mastered all the powers of the Ultimatrix. In addition to instant access for as long as he wanted (including Ultimate Forms), he could do so with all of their powers without transforming into them by instead using his own ultimate form, Ultimate Ben.
Appearances
Ultimate Alien
Season 3
- Ben 10,000 Returns (first appearance)
Trivia
- Ben started calling himself Ben 10,000 after the Plutonian revolt of 2022.[MW 1]
- The Ultimate Alien Database from the Ben 10 Ultimate Alien: The Return of Heatblast DVD claims that Ben 10,000 is married to Kai Tennyson and has two kids.[DVD 1] However, this isn't necessarily true, as the DVD mistakenly treats this Ben 10,000 as the same one from the Original Series.
Notes
- ↑ This Ben 10,000, and by extension the timeline he belongs to, was the true future of Ben Prime as of Ben 10,000 Returns,[2][1] but that has since been changed as of Omniverse, with the re-introduction of the original Ben 10,000[DJW 3][DJW 4][DJW 5] as the current true future of Ben Prime.[DJW 6] Thus, this timeline was effectively erased.[DJW 1][DJW 2][BTP 1]
