In Tekken 7, as an internet celebrity (she dons a tablet computer in one of her intros), Julia's personality has become a bit bubblier and perkier she is somewhat more hyperactive and boisterous than in previous Tekken installments. Julia's commitment to good causes tend to take precedence over her own personal life, to such a degree that she seems oblivious to the affection shown to her by others, most noticeably Ganryu, whose love has long gone unrequited. Julia is also intelligent, as her passion for her homeland led her to study archaeology, and her time spent researching forest rejuvenation taught her a great deal about natural sciences and information technology. In turn, Julia is very brave in the face of danger, and will stand her ground and fight for the side of good in order to protect the people and things she cares about. Julia is a very kind woman with a strong love for her adoptive mother Michelle, as well as her tribe and homeland. She later became a video blogger about the seventh tournament, though it's unclear if she officially entered or not. Sensing the danger to mankind, Julia entered the sixth King of Iron Fist tournament to help prevent the meeting that threatens the world.

Her plans take a back seat, however, when she learns of a greater threat to humanity - if Kazuya Mishima, Heihachi's son and Jin Kazama, who both carry the Devil Gene, are allowed to clash, a great evil will be resurrected and unleashed upon the world. With the forest rejuvenation data back in her possession, Julia returns home to realize her dreams of reforesting her homeland. While Ganryu succeeds in finding the data, Julia remained dismissive of his affection. This led him to join Julia in the fifth King of Iron Fist tournament, in the hopes of recovering the data and winning her heart. While she was unsuccessful, she did catch the attention of Ganryu, a Sumo wrestler who fell in love with her due to her resemblance to her mother Michelle, whom Ganryu had fallen in love with twenty years previously, during the second King of Iron Fist tournament. Unfortunately for Julia, the laboratories were attacked by the Mishima Zaibatsu and her research was stolen, prompting her to enter the fourth King of Iron Fist tournament in an attempt to retrieve the data. This led her to join a team of researchers led by Professor T at the G Corporation headquarters, where the project, named GENOCELL, progressed well. Julia initially wanted revenge against Heihachi, but Michelle persuaded her to return home peacefully.ДЄfter the events of the third tournament, Julia's priorities changed upon learning that the encroaching desert would soon consume her homeland, she began researching ways to restore the global ecosystem. As the tournament reached its finale, Julia successfully rescued Michelle and learned that Heihachi had used Michelle's pendant to fully awaken Ogre, the God of Fighting in an ancient Aztec temple. When she did not return, Julia suspected foul play from Heihachi and entered the third King of Iron Fist Tournament to rescue her mother. Fearing that tribal tales of the God of Fighting were coming true and that her pendant was somehow connected, Michelle headed to Japan to find Heihachi Mishima and ask him what he knew about the pendant and why he had sought it previously. Julia also developed a fascination for her tribes heritage, and began studying archaeology to learn more about her forefathers.ДЄs Julia neared her eighteenth birthday, stories started to reach the tribe of martial artists disappearing around the globe. Julia grew up with a strong love for her adoptive mother and tribe, and was taught to fight so that she could protect her homeland. Her fortunes changed, however, when she was found by Michelle Chang, a young woman from a native tribe who adopted her and raised her as her own. Julia's life got off to an inauspicious start born to unknown parentage, she was abandoned as a baby in the ruins of a Native American settlement.
