Ben Tennyson

Benjamin Kirby "Ben" Tennyson is the main protagonist of Ben 10. He was a normal 10-year-old kid until he found a mysterious alien watch called the Omnitrix, a powerful device that allows him to turn into ten different aliens with a simple touch - each with their own awesome power! Though immature and clumsy, he uses the Omnitrix to stop evil, but that doesn't stop him from using it for his own personal needs.
