Julie Yamamoto/Earth-69

Julie Yamamoto is a regular Asian/American teenager. After meeting Ben Tennyson, she and him began to date. On the two's first date at a Pier, she learned that he wielded a powerful alien watch known as the Omnitrix, which allowed Ben to be a superhero as one of a million alien forms, and also gained an alien pet the two named Ship, whom she treats like an average dog (much to the concern of Ben). She loves her pet, Ben, and helping out Ben, Gwen, and Kevin using her pet Ship.

She is currently dating Ben Tennyson, and has yet-to-be seen onscreen in Ben 10: Alien Universe. She will appear in Episode Zero of Back in Action: Alien Universe, as well as in the re-animated version of Alien Queen.
