Ben no watch(ben 10 omniverse)

Appearance: He is identical to Ben Prime, except that the hoodie he wears does not have the number "10" on it. He used to wear an old, brown wristwatch that was stolen by Kevin Levin.

Personality: Unwatched Ben lives a normal, usual life where nothing really happens to him. He is bored of the regularity in Bellwood and wants some adventure in his life. His relationship with his cousin is different as well because they don't get close to each other due to the bad summer vacation they had together. As he never faced any real danger, he was hysterical when the other Bens attacked him. Compared to his original counterpart, Ben Prime, Unwatched Ben behaves much less recklessly. Unwatched Ben also tended to get depressed due to being unable to perform heroic deeds as a result of not having his own Omnitrix, until he was animated. After obtaining his counterpart's Omnitrix, he began acting like a hero and became almost indistinguishable from his prime counterpart.
History.
Background: Watchless Ben has been JT's best friend since kindergarten and also friends with Cash Murray, who moved out of town a few years ago. At age 10, Ben and his cousin Gwen were taken on a summer road trip by their grandfather. Since Watchless Ben never got the Omnitrix, the road trip ended up being terrible. They both claim it was their worst summer. Since they didn't have fun, they never got close to each other and by the end they don't talk much, barely getting to know each other.

Omniverse: However, his life changed in The Beginning of the Ultimate after a run to Mr. Smoothy's, where he was shocked to see another person who looked just like him. Bad Ben introduced himself to Watchless Ben and suddenly attacked him. Ben was then shocked to learn that Bad Ben could transform into monsters and forced him to run away in fear. Bad Ben followed him in his Ghostfreak form, but soon Ben met others: Albedo and Benzarro. They too transformed into aliens and he again had to run away in terror, but he is soon rescued by his prime counterpart, Ben Tennyson. Ben is freaked out by what he sees, but Ben assures his other self that he is here to help him, not hurt him. That doesn't exactly calm him down, but soon Ben prime transforms into Spidermonkey to escape his evil counterparts. Both Bens soon met up with Professor Paradox and he explained to Watchless Ben that someone is kidnapping other Bens from their realities. Eon soon appears with more evil Bens along with Vilgax, Eon reveals that he wants Unwatched Ben destroyed because he sees his lack of an Omnitrix as an unpredictable wildcard. The alternate evil Bens engage in a rumble of a battle between them all, along with Ben 10,000, Gwen 10, and Ben 23.

Vilgax reveals that his true plan was to wipe out all of Ben from all dimensions except No-Watch Ben and that included Eon and the evil Bens as well. Using a Chronosapien Time Bomb, Vilgax destroyed all of reality and soon set his sights on No-Watch Ben but was saved by Paradox. Before Ben Prime faded away, his Omnitrix was transferred to No-Watch Ben and with guidance from Paradox, he intends to fix all of reality with his newfound powers. In the next episode, And There Were 10, Professor Paradox and No-Watch Ben teleport away in Vilgax's ship during the episode And There Were 10. Paradox tells him, since Vilgax destroyed the main timeline, they have to reboot the system and make sure Ben Prime finds the Omnitrix. Watchless Ben first transforms into Grey Matter and disables the ship's defenses allowing Xylene's ship to fire one last blast that mortally hits Vilgax and injures him. He then transforms into Cannonbolt and diverts the Omnitrix's trajectory into outer space. With that, the 10-year-old Ben Prime finds the Omnitrix, but doesn't walk near it. Watchless Ben transforms into Armadillo and causes a small earthquake to cause Ben Prime to fall into the pit where the Omnitrix was. Paradox tells him that he did well but his work has only just begun. Together, Watchless Ben and Paradox recruit Ben's other heroic counterparts to face the evil Bens. However, Paradox takes all the other Bens back to the point where they entered the fight in the previous episode, leaving Watchless Ben behind. Watchless Ben is momentarily saddened that he hasn't been recognized as a hero, but Paradox assures him that that wasn't his intention; Unwatched Ben in the fight would have caused two Unwatched Bens to exist simultaneously and corrupt their original timeline. Paradox brings Unwatched Ben back to his timeline, shortly after

Powers and Abilities:Like the other Bens of the multiverse, Watchless Ben possessed some degree of self-defense abilities. He also displayed sufficient control over his alien forms while he had the Omnitrix, grasping his abilities well despite his almost complete lack of prior experience.

Weaknesses: Ben No Watch lacks the prior experience and knowledge of aliens that his multiverse counterparts share.

Aliens Used: Gray Matter
Cannonbolt
Armadillo
Beast
Clockwork

Apparitions:The beginning of the last
And in the end there was Ben

Trivia:He is the main character in The Beginning of the Last and And in the End There Was Ben.
He felt bad because he was a different Ben and not a hero like the others, however, he, with the help of Paradox, was responsible for the main Ben acquiring the Omnitrix and that the battle, apparently lost with Vilgax, was won. Therefore, his person itself, is extremely important in the beginning that marked everything. He is the only Ben without an Omnitrix because Azmuth did not invent it in this dimension (if he had, someone else would have it).
Maybe after the events that occurred in And Then There Was Ben, he will have become a Plumber.
This Ben is good friends with JT and Cash, unlike the Ben with the Omnitrix in his timeline.
