While on summer vacation, Ben Tennyson stays with his Grandfather, Max Tennyson, and cousin, Gwendolyn Tennyson. During his stay at a camp, Ben discovers the Omnitrix, an alien device which allows him to change his DNA to that of various aliens and take on their form. Ben uses this device to avert disasters, save people from terror, and fight off hostile villains including Vilgax, an alien warlord bent on using the Omnitrix to outfit an alien army. He also protects the Omnitrix from evil so they cannot make use of its powers. Ben also keeps this entire situation a secret from his parents, so only Grandpa Max and Gwen know his secret. Ben also saves people from alien invasions as well as street crimes. People know him as a great superhero, but Ben is restricted and unable to reveal his secret.
