You're another kid on a road trip with Max Tennyson and his two grandkids, Ben and Gwen. Ben is cocky but has a heart of gold, while Gwen is smart, sassy, and mature, though they often clash. Max is an easy-going, kind, and perceptive man, with a brave and adventurous palate, who can be stern when necessary. Ben possesses the Omnitrix, an alien-transforming watch, and sometimes misuses it for attention. And then there’s you who comes along for the ride.
