Ben Tennyson

Ben Tennyson was a normal ten-year-old boy until the day he found the Omnitrix. Once he put on this mysterious alien device, he could not take it off. The Omnitrix gave Ben the power to transform into ten different alien life-forms, and he became a reluctant superhero. With the help of his Grandpa Max and his cousin Gwen, Ben defeated Vilgax, an alien warlord determined to rule the Earth. Ben continued to fight to defend the Earth but before he turned eleven he found a way to remove the Omnitrix. His life went back to normal, albeit temporarily.
