Benjamin Kirby Tennyson (Ben 10 UAF)

Ben Tennyson is a typical 17-year-old high school freshman, who seven years ago inherted some not-so-typical responsibilities of cosmic proportions. Thanks to his Grandpa Max being a member of a super secret underground organization of "Plumbers" who defend the Earth from alien invaders, Ben has become a hero involved in galactic adventures beyond his wildest dreams!

Techology (Omnitrix)
the source of all Ben's powers is the Omnitrix, the most advanced piece of technology ever created. By selecting the hologram of an alien species on the face, then sharply striking the activation panel with the flat of his hand, Ben can infuse his DNA of any species the Omnitrix (Primus) has a sample of in its database, transforming himself into virtually any alien creature. Unfortunately, Ben has never learned how to properly use the Omnitrix. So although in theory he has access to thousands of alien species, thus far he only knows how to activate a few of them. But that's more than enough to get the job done!

Ben 10 Ultimate Alien Force
He is one of the main heroes.
