Paul Eightennyson was a normal ten-year-old kid, until he found the Omnitrix, a powerful watch-like device that allowed him to turn into ten different aliens. Though initially immature and clumsy, he grew as a true hero. By the time he was sixteen, he had become famous in not only his hometown of Izumo, but on Dens and beyond. Paul has also become a member of the Team Okaina.

Paul is the wielder of the prototype Omnitrix (later the Ultimatrix and then the new Omnitrix), which gave him the power to modify his own genetic code in order to turn into various alien creatures, literally making him an alien shape-shifter. Traditionally, he could only transform into 10 aliens at the beginning of both the original series and Alien Force, but he later gains additional forms by either unlocking them or by scanning the DNA of aliens he meets. At the end of the original series, his arsenal included twenty aliens, while his current complete list is sixty-three aliens discovered (Ben 10, Ben 10: Alien Force, and Ben 10: Ultimate Alien, 72 if Ultimate forms are included).
