- "It's all...a dream. "
Initially Vicious's girlfriend and possibly a Syndicate member herself, she once nursed Spike back to health after he was critically injured and collapsed outside her apartment. It's presumed this is where she and Spike started a dangerous affair that led to Spike offering to abandon the Syndicate and elope with her, despite the fact that the Syndicate punishes desertion with death. Arranging to meet at a graveyard later, Spike knowingly walks into an ambush, resulting in a violent gun battle where he is presumed by the Syndicate to have died. Vicious had discovered the affair, however, and confronts Julia, telling her that she would have to kill Spike at the graveyard, or else they would both be killed. To protect not only herself but also the man she loved, Julia goes into hiding, never meeting Spike as both of them had planned; Spike himself was never aware of Vicious' threats until the very end of the series. Because of this, Spike is led to believe that Julia betrayed him, and adopts his characteristic fatalist mentality.
In 2069, Julia went to Callisto and met Gren at the Blue Crow. They became friends and so she told Gren about Spike and he told her about Vicious and the music box he gave him. Immediately, she told him to check inside the music box, revealing a solar transmitter which signaled Vicious betrayed Gren. After about a month, Julia left. 
After meeting Faye Valentine by coincidence, she and Faye escaped a Red Dragon Hit team after them. With Faye mentioning Spike, she left Faye a message saying "its time." And briefly explains that Spike would understand what it means.
Julia and Spike are reunited in a graveyard where they decide to run away together. However, soon they are ambushed by henchmen at Annie's convenience store, and one of the men fatally injures Julia. As she lays dying in Spike's arms, she whispers her last words to him: "It's all a dream". which he responds back to "Yeah just a dream."
Despite being among the main driving points for the entire series, Julia only appears in flashbacks until the final two episodes. She acts as a stark contrast to the world around her—her blonde hair and bright red umbrella and automobile stand out in the otherwise drab environments that she inhabits.
- She is named after the song "Julia" by The Beatles.
- She appears in all the episodes Vicious is in.
