Julie Yamamoto

Julie Yamamoto is Ben's ex-girlfriend and now friend. She first appeared in Ben 10 Returns: Part 1 at Ben's soccer game to congratulate him on his game-winning goalie work. She later broke up with Ben some time between The Ultimate Enemy: Part 2 and Rules Of Engagement.

Appearance
Julie wears a black t-shirt, mostly hidden under a pink hooded jacket and a white mini skirt. When playing tennis, she wears white wristbands, a white t-shirt, and her skirt. She has short black hair and sports white tennis shoes.

In Omniverse, Julie looks similar to her Alien Force/Ultimate Alien appearance except now she has a white t-shirt instead of a black one. She still has her old pink jacket, but now with light orange, yellow, and white stripes on it. She also now has longer hair in pig tails and there are thin black lines across her skirt. She also has long socks that go up to her knees. Her face now shows more Japanese traits than before.

Powers and Abilities
Being an ordinary human, Julie doesn't possess any superpowers herself, although she's quite good at tennis, and shows some fighting ability in Pet Project where she takes one of the Forever Knights electric maces and easily knocks out several Forever Knights with them (one of these knights being comically unintentional while she replied to Gwen's acknowledgement). Julie is the only one who can fully command Ship, making her a competent ally.

In Vreedle, Vreedle, Ship reveals that he can "merge" with Julie. When Ship enveloped her, he became a armored battlesuit. In the suit, she demonstrates enhanced strength and great damage resistance, as well as the ability to fire powerful lasers.

In Eye of the Beholder, it turns out that Julie can understand Ship's language.
