In the Gweniverse, Ben is not an Anodite [DJW 5] and does not know magic. [DJW 6] In fact, he does not have any powers in general. [DJW 7] He is essentially a tagalong that gets in Gwen's way.

Ben's physical appearance has changed throughout the series from a 10-year-old to a 16-year-old. However, he retains some recurring characteristics. He has unkempt brown hair, green eyes, pale skin, and he is quite skinny for his age, though he shows a lot of muscle definition due to being athletic. The Omnitrix appears in the first two incarnations of the franchise ( Ben 10 and Ben 10: Alien Force), but Ben had to destroy it and use the Ultimatrix in the Ultimate Alien series. The Ultimatrix had most of the same functionality as the Omnitrix, but would allow the user to transform the alien into its Ultimate Form (how the species and its DNA would evolve in a one-million-year simulation). In the final episode of Ultimate Alien, Azmuth takes the Ultimatrix from Ben and replaces it with the New Omnitrix–the original version has been a prototype.Ben's fight with his hero ( Kangaroo Commando) in Super Alien Hero Buddy Adventures is one of his favorite memories.
