Ben Tennyson , more commonly known as Ben 10,000, is the Ben 10,000 Timeline version of Ben Tennyson.

As a kid, Ben was much like his Prime Timeline counterpart, Ben was a 10  year old kid who loved being a superhero, saving the world, fighting of evil aliens and having Fun. When Ben Was ten year’s old he had to return home after the Summer Vacation Because Summer was over and he had to go back to school and live a normal life again. Then Vilgax showed up and wanted to destroy Ben and his hometown but luckily Ben Defeated Vilgax Also Ben’s Secret Identity was revealed to the world when he defeated Vilgax and his drones. And he became so Famous.And he unlocked every single alien inside the omnitirx. At age 15, Ben fought Vilgax. It’s unknown what exactly happened, but Ben mutilated Vilgax.

Ever since mutilating Vilgax, Ben became very cynnical and serious about the hero business to the point that it was almost obsessive. He stopped naming his aliens, stopped counting once he reached 10,000 unlocked aliens, unlocked the Master Control and rarely turned back to his human form, spending most of his time as XLR8 and rudely refused to let other heroes, like the Galactic Enforcers, help fight bad guys.

Ben 10,000 stayed this serious until he encountered Ben Prime and fought Vilgax alongside him in Ben 10,000. After Ben Prime pointed out that Vilgax knew everything his aliens could do, but didn’t know what Ben Tennyson can do, Ben 10,000 used his human form to surprise Vilgax, having fun while doing so, and lightened up just in time for his Grandpa Max’s 80th birthday, naming his aliens again.
