Powers and AbilitiesEdit
Being an ordinary human, Julie doesn't possess any super powers herself, although she's quite good at tennis, and shows some fighting ability in Pet Project. She's also 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 battle suit. In this suit, she demonstrates enhanced strength and great damage resistance, as well as the ability to fire various powerful weapons. In The Eye of the Beholder, it turns out that Julie can understand Ship's language.
