First Appearance And Then There Were 10

Benjamin "Ben" Kirby Tennyson was an average ten-year-old kid, until he found the Omnitrix, a powerful watch-like device that allowed him to turn into ten different alien species. Though initially immature and clumsy, he grew as a true hero. By the time he was sixteen, he had become famous in not only his hometown of Bellwood, but on Earth and beyond. Ben has also become a member of the Plumbers.
